Description

The present invention relates to a sweeping device for a vehicle.

Sweeping devices that can be attached to vehicles are known per se. For example, the DE 10 2011 051 223 A1 a sweeping device for a vehicle, comprising a pick-up device for picking up the sweeping device by means of the vehicle, a broom and a clearing blade arranged longitudinally in front of the broom. In this sweeping device, the clearing blade and the broom are firmly connected to each other and can be pivoted together about different axes. DE 3102659 A1 , WO 2013/135309 A1 , U.S. 2011/303240 A1 and DE 29502693 U1 describe other similar sweeping devices.

It is desirable to be able to use sweeping devices flexibly for various sweeping or clearing work. Neither the sweeping devices nor a surface to be cleaned should be subjected to excessive stress or wear.

It is the object of the present invention to provide a sweeping device which can be adapted particularly easily and flexibly to different sweeping conditions. This object is achieved by a sweeping device for a vehicle having the features of the independent claims.

Further possible configurations of the invention are specified in particular in the dependent claims.

The sweeping device according to the invention for a vehicle comprises a pick-up device for picking up the sweeping device by means of the vehicle and a broom. Said receiving device can include one or more mechanical interfaces, so that the sweeping device can be attached to one type of vehicle or to different types of vehicles. For example, the receiving device can be designed to attach the sweeping device to a telehandler, a front loader or the like.

Height-adjustable skids are arranged on the side of the broom, which limit the maximum possible compression of the respective bristles of the broom in the vertical direction of the sweeping device. Depending on the nature of the ground to be swept and/or depending on the nature of the bristles of the broom, it is possible by means of the height-adjustable skids to determine how much the respective bristles of the broom can be compressed in the vertical direction of the sweeping device. For example, it is possible for the height-adjustable skids to be used to compensate for wear on the bristles of the broom. If the bristles are new, they are relatively long, for example, whereas the bristles can become shorter due to constant wear. The height-adjustable skids ensure that the bristles are always pressed onto the ground with sufficient contact pressure and are in contact with it, so that a good sweeping effect can be achieved. On the underside of the height-adjustable skids, for example, sliding strips, for example made of polyurethane or the like, can also be arranged. As a result, a floor to be cleared or swept can be protected. Furthermore, the skids themselves do not wear out, only the slide rails, which can be replaced if necessary. The skids can, for example, be fixed steplessly or in individual steps in different positions. The latter can be realized, for example, in that the skids are guided in corresponding receptacles, which in turn have a hole, by means of perforated rods or the like. The skids can then be fixed in a respective position using a bolt.

Alternatively or in addition to the height-adjustable skids, the sweeping device according to the invention comprises an attachment that can be mounted in the longitudinal direction of the sweeping device in front of the broom for clearing a subsurface, which in the mounted state is mounted at least indirectly on the broom by means of a holding device and can be moved relative to the broom by means of the holding device. The attachment can thus be dismantled from the rest of the sweeping device, as can the holding device. The sweeping device can also include several different types or variants of attachments that can be attached in front of the broom. The holding device can be designed to accommodate all the different types or variants of the add-on parts and to store them at least indirectly on the broom so that they can move relative to it. If the attachment is not required, the broom can be used without the attachment, for example because it is being swept There are no particularly large pieces of dirt or large amounts of snow lying on the ground. If, on the other hand, there are large pieces of dirt, pieces of scrap metal, masses of snow or the like lying on the surface to be cleaned, the attachment can be mounted in front of the broom.

In the mounted state, the attachment is therefore arranged in front of the broom in the longitudinal direction of the sweeping device. This means that, based on an intended sweeping direction of the broom, the attachment is arranged in front of the broom. If the sweeping device is moved by means of the vehicle over a surface to be swept or cleaned with the attachment mounted, the attachment first comes into contact with dirt, snow or the like to be removed. Large or bulky elements in particular can therefore be cleared away by means of the attachment before the broom ensures that the surface to be swept is cleaned as thoroughly as possible. In this way, a particularly good sweeping and clearing effect is achieved by means of the sweeping device just by driving over a subsurface once.

Because the attachment is mounted at least indirectly on the broom by means of the holding device and can be moved or adjusted relative to the broom by means of the holding device, the sweeping device can be adapted particularly easily and flexibly to a wide variety of sweeping conditions. The attachment can therefore be adjusted relative to the broom, regardless of the position of the broom. For example, the attachment can be mounted on the upper side of the broom by means of the holding device, directly or indirectly. Of course, this does not mean that the attachment is attached to the respective bristles of the broom. The attachment can, for example, on a housing of the broom - directly or indirectly - be mounted through the intermediary of the holding device. Said housing can serve to accommodate the bristles of the broom. The holding device has suitable means in order to be able to adjust the attachment relative to the broom. Adjusting is to be understood in particular as meaning that the attachment can be moved in a translatory and/or rotary manner relative to the broom.

The broom can therefore always be arranged in such a way that a particularly good sweeping effect is achieved. Depending on the sweeping or clearing task and the boundary conditions, the attachment can be adjusted relative to the broom in order to also achieve a particularly good clearing effect without damaging the attachment and a surface to be swept and cleared.

The attachment can be a snow blade or a shovel. Depending on what kind of ground is to be cleared or cleaned, it may be advisable to mount a clearing blade or a shovel. If, for example, snow is to be cleared by means of the sweeping device, it may be advisable to provide a clearing blade as the attachment. By tilting the blade, snow to be cleared can be cleared to the right or left, after which any remaining snow can be swept away from the ground using the broom. If, on the other hand, dirt to be cleared or, for example, snow can be transported away or removed as quickly as possible without simply clearing the snow or dirt to the side, it can be advisable to use a shovel as the attachment. Using the shovel, it is possible to pick up materials to be cleared and, if necessary, to clear them away immediately by lifting the filled shovel, so that materials picked up by means of the shovel can be removed.

A possible embodiment of the invention provides that the attachment can be pivoted about a vertical axis relative to the broom by means of the holding device. The attachment can thus be adjusted by means of the holding device obliquely to the longitudinal direction of the sweeping device and thus also obliquely to the intended sweeping direction of the broom. For example, it is possible to pivot the attachment in such a way that coarse dirt and/or snow can be pushed away to the right or left by means of the sweeping device, for example during a combined sweeping and clearing process. Regardless of the position of the attachment, the orientation of the broom can remain in such a way that an optimal sweeping effect is achieved. A transverse direction of the broom can, for example, remain aligned transversely to a direction of movement or direction of travel of the sweeping device, while the attachment, on the other hand, is set at an angle to the direction of travel or sweeping direction of the broom, i.e., for example, an acute angle between a front side of the attachment and a forward travel and thus sweeping direction includes. For example, several rows can be covered with a vehicle to which the sweeping device is attached, with the attachment, for example, snow being always cleared away to the left or right when driving on the respective rows. Any remaining snow on the ground behind the attachment is then removed using the broom. Of course, this can also be done for all other types of dirt or similar to be removed.

The invention provides that, in order to pivot the attachment around the vertical axis, the holding device has two telescopic rods that can be extended independently of one another and that, based on the transverse direction of the sweeping device, are arranged at least indirectly on the broom in a left and right area and at least indirectly on the rear of the attachment with a rotational degree of freedom are stored around the vertical direction. By extending or retracting the respective telescopic rods to different extents, the add-on part can easily be pivoted or rotated about the vertical axis of the holding device. Because the telescopic rods are mounted at least indirectly on the attachment with a rotational degree of freedom about the vertical direction, the attachment can easily pivot relative to the respective telescopic rods when the telescopic rods are extended and retracted. When extending and retracting the telescopic rods, relatively small forces, which result from the pivoting of the attachment, act on the sweeping device.

According to the invention, it is provided that the telescopic rods have a first telescopic element attached at least indirectly to the broom and a second telescopic element that can be extended from this, which can be fixed in different extended positions on the respective first telescopic element. The second telescopic elements can thus be moved out of and into the respective first telescopic elements to different extents. For example, the second telescopic elements can have a plurality of holes arranged one behind the other in relation to the longitudinal direction of these telescopic elements, it being possible for the second telescopic elements in turn to each have a hole. By pushing a respective bolt through the respective one hole of the first telescopic elements and through one of the respective holes of the second telescopic elements, the latter can easily be fixed in an extended position. However, it is just as possible that the second telescopic elements can be fixed steplessly, ie can be fixed in any extended and retracted positions on the first telescopic element. For this purpose, respective clamping devices can be provided on the telescopic rods.

The invention provides that the height of the attachment can be adjusted relative to the broom by means of the holding device. If the ground to be cleared is very uneven, for example, it is possible to use the attachment to Raise the holding device a little so that neither the subsurface nor the attachment are damaged by the unevenness of the subsurface.

According to a further possible embodiment of the invention, it is provided that for the height adjustment of the attachment, the holding device is pivotable about a transverse axis of the sweeping device, at least indirectly mounted on the broom. For example, if you want to raise the attachment a little, the holding device simply has to be pivoted accordingly about the transverse axis of the sweeping device. This results in a particularly simple and space-saving way of adjusting the height of the attachment relative to the broom.

The invention provides that the holding device rests at least indirectly on the broom in a lower pivoted position and can be freely pivoted upwards from there, so that the attachment can move upwards following uneven ground. If the sweeping device travels over bumps in the ground, the mounting part described can simply dodge upwards following the bumps in the ground. This ensures that neither the attachment nor the subsurface in question are damaged. In other words, a kind of oscillating mounting of the attachment on the broom is provided. In the lower pivoted position, the broom rests at least indirectly on the broom through the intermediary of the holding device, as a result of which the lower pivoted position is defined. The lowest possible arrangement of the add-on part is thus defined by the lower pivot position, in which the holding device rests at least indirectly, in particular on the upper side, on the broom. As a result, hardly any forces or no large forces act on the pivotable mounting of the holding device. Starting from this lowest possible position, the attachment can move upwards at any time without any problems, e.g. if a bump or similar is driven over. Because due to the described pivotable mounting of the holding device about the transverse axis, the holding device is automatically pivoted about the transverse axis together with the attachment when crossing uneven ground by means of the attachment. As a result, the attachment automatically deviates upwards following the unevenness of the ground.

In a further possible embodiment of the invention, it is provided that the lower pivoting position of the holding device and thus an angle of attack between the holding device and the broom can be varied by means of at least one screw drive. In the holding device can, for example, be embedded in weld nuts. For example, screws serving as screw drives can be screwed into these weld nuts. Depending on how far these screws are screwed in, the lower pivot position changes, since under the action of the screws the holding device is moved away from the broom or raised by the holding device being pivoted accordingly about the transverse axis. Depending on what position is desired in relation to the vertical direction with regard to the add-on part, the lower pivoting position can be easily changed. By means of the at least one screw drive, it is possible to adjust the lower pivoting position of the holding device and thus a distance between a lower edge of the add-on part and a base without particularly great force.

In addition, another possible embodiment of the invention provides that the sweeping device has a radio transmitter with an integrated inclination sensor, which is designed to detect an inclination of the broom, in particular about its transverse axis, and transmits data characterizing the inclination to a receiver, in particular a smartphone , to send. A driver of the vehicle by means of which the sweeping device is moved can, for example, simply use his smartphone to see whether the inclination of the broom, in particular about its transverse axis, is set correctly. In particular, correct can mean that all the bristles of the broom are arranged at the same height and thus evenly touch the surface to be cleaned or swept. This can ensure that the bristles of the broom are not worn differently. If the vehicle is, for example, a tractor with a front loader, the driver can operate the front loader accordingly until the radio transmitter shows him that the incline of the broom is set correctly or optimally. The driver of the vehicle in question does not even have to leave his vehicle to check the correct adjustment of the inclination of the broom.

According to a further possible embodiment of the invention, it is provided that if the add-on part is a shovel, the shovel is mounted on the broom such that it can pivot about an axis running in the transverse direction. In particular when the sweeping device is mounted on a vehicle by means of which the shovel itself cannot be tilted, it is advantageous if the shovel is mounted on the broom so that it can pivot about said axis running in the transverse direction. In this context, it can also be provided that the blade can be pivoted about the axis by means of an adjustment unit. The adjustment unit can have at least one actuator which is designed to pivot the blade hydraulically, pneumatically, electrically or magnetically about the axis. For example, the actuator can be a hydraulic cylinder or a pneumatic cylinder. However, other types of actuators are also possible. When the bucket has been filled with material to be removed and raised, it is possible, for example, to pivot the bucket downwards about the transverse axis in order to easily empty the bucket. The sweeping device can, for example, have an interface for a vehicle, so that it is possible from the vehicle, for example by controlling the at least one actuator, to pivot the shovel very easily if necessary. In principle, manual swiveling of the blade is also possible.

A further possible embodiment of the invention provides that the sweeping device has a lock, by means of which a pivoting movement of the shovel about the axis can be blocked. The locking device can include a bolt or a screw, for example, by means of which the pivoting movement of the blade about the axis can be blocked. This is particularly helpful when the sweeping device is attached to a vehicle which itself can carry out a tilting movement on the entire sweeping device and thus also on the shovel, for example when the sweeping device is attached to a front loader.

In a further possible embodiment of the invention, it is provided that at least one further height-adjustable skid is arranged in a front area and/or at a rear area on the broom, which limits the maximum possible compression of the respective bristles of the broom in the vertical direction of the sweeping device. Several of the other skids can also be arranged on the front and/or rear. In particular, it can be provided that at least one of the further skids is arranged on the front and rear. Together with the laterally attached skids, a compression of the bristles of the broom can be prevented in a particularly reliable manner. The other skids can, for example, be clamped with screws and guided with infinitely variable height adjustment.

Further possible configurations and features of the invention are specified in the following description of the figures. The features and combinations of features mentioned above in the description and the features below in the description of the figures and/or in The features and combinations of features shown alone in the figures can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the invention, which is defined by the claims.

A sweeping device 10 for a vehicle, not shown here, is shown in a perspective view at an angle from the front in FIG 1 shown. The sweeping device 10 includes a receiving device 12 for receiving the sweeping device 10 by means of the vehicle. The vehicle can be, for example, a telehandler, front loader or the like. In addition, the sweeping device 10 comprises a broom 14 and an attachment arranged in the longitudinal direction x of the sweeping device 10 in front of the broom 14 for clearing a subsurface in the form of a clearing blade 16. The clearing blade 16 is mounted on a housing 20 of the broom 14 by means of a holding device 18 at the top. For the sake of clarity, the reference number for the holding device 18 has been entered twice here. The holding device 18 comprises a number of elements which are described in more detail below.

The clearing blade 16 can be adjusted relative to the broom 14 by means of the holding device 18 . On the one hand, the clearing blade 16 can be pivoted relative to the broom 14 by means of the holding device 18 about a vertical axis running parallel to the vertical direction z. In addition, the clearing blade 16 can be adjusted in height relative to the broom 14 by means of the holding device 18 . To adjust the height of the clearing blade 16, the holding device 18 is mounted on the broom 14, more precisely on the upper side of the housing 20 of the broom 14, about a transverse axis 22 of the sweeping device 10 running parallel to the transverse direction y.

On opposite sides, respective height-adjustable skids 24 are arranged laterally on the broom 14, which limit a maximum possible compression of respective bristles 26 of the broom 14 in the vertical direction z of the sweeping device 10. By retracting or extending the skids 24, the distance between the housing 20 of the broom 14 and a ground can be adjusted. In other words, the skids 24 determine how far the sweeping device 10 can be lowered in the direction of the ground. Even if, for example, the sweeping device 10 is pressed firmly down with a front loader, the height-adjustable skids 24 ultimately limit how firmly the respective bristles 26 of the broom 14 are pressed against the ground and thereby compressed.

The sweeping device 10 also includes a radio transmitter 28 with an integrated inclination sensor, which is designed to detect an inclination of the broom 14, in particular about its axis running parallel to the transverse direction y, and to transmit data characterizing the inclination to a receiver, for example to a smartphone To send the driver of the vehicle, by means of which the sweeping device 10 is moved. It is thus very easily possible for the driver, without leaving the vehicle in question, to check or recognize whether the bristles 26 of the broom 14 are aligned as optimally as possible with the subsurface to be swept. Optimal means in particular that the incline of the broom 14 is tilted about the axis running parallel to the transverse direction y such that the bristles 26 are all at least essentially the same distance from the ground or all bristles 26 touch the ground evenly.

If this is not the case, the driver can change the inclination of the broom 14, for example, by appropriately operating the front loader of the vehicle the radio transmitter 28 with the integrated inclination sensor shows the driver, for example, in turn on his smartphone, eg by means of a suitable app, whether the best possible arrangement or inclination of the broom 14 has been set. The radio transmitter can have a Bluetooth module, for example, in order to wirelessly transmit the data characterizing the inclination of the broom 14 to the driver's smartphone via Bluetooth. Other wireless transmission technologies are of course also possible, such as WLAN or the mobile network.

In 2 the sweeping device 10 is shown in a plan view from above. For pivoting the clearing blade 16 about the vertical axis, the holding device 18, which is not specified here, has two telescopic rods 30 that can be extended independently of one another and that, in relation to the transverse direction y of the sweeping device 10, are mounted at least indirectly on the broom 14 in a left and right area, here specifically on the upper side the housing 20 of the broom 14 are arranged. In addition, the telescopic rods 30 are each mounted at least indirectly on the back of the clearing blade 16 with a degree of freedom of rotation about the vertical direction z. As can be seen here, the clearing blade 16 can be pivoted relative to the broom 14 by extending or retracting the telescopic rods 30, so that an angle α between a front side 32 of the broom 14 and a rear side 34 of the clearing blade 16 can be varied.

The telescopic rods 30 each have a first telescopic element 36 which is attached at least indirectly to the broom 14 and a second telescopic element 38 which can be extended from this and which can be fixed to the first telescopic element 36 in positions that have been extended to different extents. The first telescopic elements 36 each have a hole 42, the second telescopic elements 38 having a plurality of holes 40 arranged one behind the other. As soon as one of the holes 40 has been made to overlap with the relevant hole 42, a bolt can be inserted through the relevant holes 40, 42, for example, to adjust the respective position of the second telescopic elements 38 and thus the angle α at which the plow blade 16 is relatively was pivoted to the broom 14 to fix. Stepless adjustability and above all fixability of the second telescopic elements 38 on the first telescopic elements 36 is of course also possible. This can be implemented using a suitable clamping device, for example.

In the present illustration, said transverse axis 22 can again be clearly seen, about which the holding device 18, which is not described in any more detail here and comprises the telescopic rods 30, can be pivoted in order to adjust the height of the clearing blade 16. In the case shown here, the first two telescopic elements 36, which are connected to the holding device 18 (see 1 ) belong to the transverse axis 22 pivotally mounted on the broom 14, more precisely on the housing 20 of the broom 14 on the top side. In all figures, the holding device 18, and thus also the first telescopic elements 36, are shown in their lower pivoted position. In this lower pivoted position of the holding device 18, the latter rests with its first telescopic elements 36 on the housing 20 of the broom 14. Starting from this lower pivoted position, the holding device 18 and thus also the clearing blade 16 can be freely pivoted upwards, so that the clearing blade 16 can move upwards following uneven ground. So if the sweeping device 10 drives over an uneven ground, the plow blade 16 can easily move upwards when driving over the uneven ground due to the pivotable mounting of the holding device 18 about the transverse axis 22 . Damage to the clearing blade 16 and also damage to the subsoil in question can be avoided in this way.

The lower pivot position of the holding device 18 and thus an angle of attack between the holding device 18 and the broom 14 can be designed to be variable by means of at least one screw drive. In the case shown here, respective weld nuts 44 are attached in the area of through-openings of the first telescopic elements 36, which are not designated in any more detail. For example, a respective screw can be screwed in through these weld nuts 44 . Depending on how far or how deep the screw is screwed in, the first telescopic elements 36 are pushed upwards by the housing 20 of the broom 14 by means of the respective screws. The first telescopic elements 36 are designed, for example, as hollow profiles or as U-shaped profiles. In the latter case, the first telescopic elements 36 are then downwards—that is, in the direction of the housing 20—open. For example, said screws can be supported directly on the housing 20 and, depending on the screwing depth, pivot the telescopic rods 30 together with the clearing blade 16 up or down. Due to the pivotable mounting about the transverse axis 22, an inclined position of the entire holding device 18 and thus of the clearing blade 16 is thus influenced. In this way, the lower pivoting position of the holding device 18 and thus the lowest possible position of the clearing blade 16 can be set very easily.

In 3 the sweeping device 10 is shown in a perspective view obliquely from behind. In the present representation, the pick-up device 12 can be clearly seen, which is used to pick up the sweeping device 10 by means of a vehicle, for example by means of a front loader, a telescopic loader, a forklift truck or the like. In the case shown here, the receiving device 12 has a number of different interfaces at which a respective vehicle can grip or pick up the sweeping device 10 .

On the one hand, the receiving device 12 has a plate 46, which can be used, for example, as an interface for a front loader that can be screwed on. If, for example, a shovel was removed from the front loader, the front loader can be screwed to the plate 46 with its corresponding interface. In addition, the receiving device 12 has receiving areas 48 into which, for example, tines of a telehandler or a forklift can be inserted. In the present case, the receiving areas 48 are provided by hollow profiles, not designated in any more detail, which are fastened to the housing 20 of the broom 14 on the top side. The receiving device 12 also includes two receiving areas 50 to the left and right of the plate 46, into which, for example, a shovel of a wheel loader can be moved. These receiving areas 50 are delimited by two profiles 52, 54, with respective weld nuts 56 being fastened in the upper of the two profiles 54. For example, screws can be screwed in through these weld nuts 56 in order to fix a wheel loader or front loader shovel introduced into the receiving area 50 . Deviating from the present illustration, the receiving device 12 can, for example, also have a type of framework which has the shape of bales, so that a bale tongs of a vehicle can grasp the framework in order to accommodate the sweeping device 10 .

Positioned on the left and right on respective sides of the broom 14 (not designated in any more detail) or on its housing 20 are respective dipsticks 58. These make it easier for a driver of a vehicle in question, by means of which the sweeping device 10 is picked up and moved, to estimate where the sweeping device 10 ends laterally. If, for example, an excavator is used to pick up the sweeping device 10, a backhoe shovel could, for example, partially or completely block the driver's view of the sweeping device 10, apart from the dipsticks 58 See dipsticks 58 so that he can easily estimate where the sweeping device 10 or at least the broom 14 ends laterally.

In 4 1, the sweeping device 10 is shown in a side view with the plow blade 16 not mounted on the rest of the sweeping device 10. FIG. One of the two height-adjustable skids 24 can be seen clearly in the present illustration. The skids 24 are fixed laterally to the housing 20 of the broom 14 by means of hollow profiles 60 . Receptacles 62 are arranged on the respective longitudinal sides of the housing 20 and serve to receive and fix the hollow profiles 60 in different positions.

In the present setting of the height-adjustable skids 24, they are extended or retracted so far that in the unloaded state the bristles 26 touch the ground and the skids 24 do not. If the sweeping device 10 is pressed downwards in the vertical direction z, at some point the underside of the skids 24, which is not specified, will come into contact with the ground and thereby limit a further lowering of the sweeping device 10 and thus further compression of the bristles 26 of the broom 14. This can prevent this that the bristles 26 are compressed or crushed too much. At the same time, a suitable setting of the skids 24 can ensure that the bristles 26 exert sufficient contact pressure on the ground with appropriate pressure exerted on the sweeping device 10 downwards, so that a good sweeping effect or cleaning effect of the ground can be achieved.

In figure 5 the sweeping device 10 is shown in a front view, with, among other things, the clearing blade 16 not being mounted. As can be seen, the bristles 26 of the broom 14 extend at least substantially over the entire width of the broom 14. The individual bristles 26 can be combined, for example, in bristle packs or bristle modules, which are not shown in detail, and on the underside or inside of the housing 20 of the broom 14 be attached. In addition, one can again clearly see the arrangement of the skids 24, which are attached to the left and right side of the broom 14. On the underside, non-specified sliding strips can be attached to the skids 24, which can be made of polyurethane, for example. As a result, a subsurface to be swept or cleaned can be protected, at the same time it can be prevented that the skids 24 themselves are worn out. As soon as the wear strips are worn out, they can be easily replaced.

The bristles 26 can also be arranged one behind the other in different rows. The clearing blade 16, not shown here, can be provided on the underside, for example, with a scraper bar made of highly wear-resistant steel or also made of polyurethane. In addition, it is also possible for the sweeping device 10 to have different variants of clearing plates 16 that can be installed, which can differ, for example, with regard to their size or also with regard to their material properties.

In 6 is the in figure 5 Marked section A shown in a detailed view. One of the two skids 24 can be seen here, which is fixed in a height-adjustable manner to the receptacle 62 through the intermediary of the hollow profile 60, which in turn is fastened to the housing 20 of the broom 14, not designated in any more detail here. The receptacle 62 has a through-opening or a hole 64, the hollow profile 60 for its part having a plurality of through-openings or holes 66 arranged one behind the other in a row or one above the other. As soon as one of the holes 66 has been made to overlap with the hole 64, a bolt, for example, can be inserted through the relevant holes 64, 66 in order to fix the skid 24 in a specific height setting. A stepless fixability of the skids 24, for example by a suitable clamping device, can also be provided.

By means of the sweeping device 10 explained, it is very easily possible, in particular, to adapt the position or arrangement of the clearing blade 16 relative to the broom 14 to the most varied of boundary conditions. By means of the sweeping device 10 it is possible to sweep and clean a subsurface in a very short time. In winter, for example, it is also possible to push snow away by means of the slanted snow blade 16 and at the same time to sweep away the residual snow left behind cleanly by means of the broom 14 .

Even with uneven surfaces, it is possible to clean the ground without damaging the surfaces in question and without damaging the clearing blade 16 . The fact that the clearing blade 16 is mounted in an oscillating manner about the transverse axis 22 through the intermediary of the holding device 18 means that the clearing blade 16 can simply dodge upwards if necessary following uneven ground. Since the bristles 26 of the broom 14 have a certain flexibility, they can continue to be pressed onto the ground when driving over bumps in the ground, with - depending on the local condition of the ground - the Height-adjustable skids 24 can ensure that the bristles 26 are not compressed too much and thereby affected. Said radio transmitter 28 with the integrated inclination sensor also facilitates the optimal setting or arrangement of the broom 14, so that the bristles 26 of the broom 14 are worn evenly and not unevenly.

In 7 a second embodiment of the sweeping device 10 is shown in a perspective view obliquely from the front, the attachment for clearing the subsoil in this embodiment being a blade 68 which is adjustable relative to the broom 14 . The adjustment options for blade 68 may be the same as for the blade 16 embodiment. The height-adjustable skids can also be provided in the second embodiment. In addition, the blade 68 can be tilted or pivoted about an axis running in the transverse direction y, if required. The use of the shovel 68 can be helpful in particular when dirt or other materials are not only to be pushed off the sweeping device 10, but are also to be poured into a container or the like, for example. By means of the shovel 68 accumulated materials can easily be picked up and disposed of directly.

The blade 68 can be pivoted about said axis, which runs in the transverse direction y, by means of an adjustment unit. In the case specifically shown here, the adjustment unit, not designated in any more detail, comprises two hydraulic cylinders 70 serving as actuators, by means of which the shovel 68 can be pivoted about the pivot axis running in the transverse direction y, if required.

In 8 the second embodiment of the sweeping device 10 is shown in a perspective rear view. In the present case, one can clearly see that the hydraulic cylinders 70 are attached to the broom 14 at the top and to the shovel 68 at the rear. The attachment or mounting of the hydraulic cylinders 70 is articulated, so that said tilting movement or pivoting movement of the shovel 68 can be carried out without any problems.

In 9 is the in 8 labeled area B shown enlarged. One of the two hydraulic cylinders 70 can again be clearly seen here, which can tilt or pivot the shovel 68 by retracting or extending it.

In 10 is the in 8 marked area C shown enlarged. In the present case, the axis 72 already mentioned has now been provided with a reference number, which runs in the transverse direction y, about which the blade 68 can be tilted or pivoted. A locking device 74 can be seen here, by means of which a pivoting movement of the blade 68 about the axis 72 can be blocked. In the case shown here, the locking device 74 is a nut, which can be screwed onto a bolt or a screw, for example. By tightening the nut, the pivoting movement or tilting movement of the blade 68 about the axis 72 can be blocked. This can be helpful when the entire sweeper 10 is mounted on a vehicle that can tilt the sweeper 10 and thus the bucket 68 as well. For example, the vehicle can be a front loader on which the sweeping device 10 is attached. In that case, it is not necessary to tilt the bucket 68 by actuating the hydraulic cylinders 70 accordingly.

The sweeping device 10 can also include different variants of the clearing blade 16 and the shovel 68, all of which can be compatible with the rest of the sweeping device 10, ie can be mounted and fixed in the manner described in particular on the upper side of the broom 14.

In 11 a third embodiment of the sweeping device 10 is shown in a perspective rear view. The third embodiment differs from the previous embodiments in that the sweeping device 10 has further height-adjustable skids 76 in a front and/or rear area. Two of the other skids 76 can be seen here, which are arranged on the back of the housing 20 of the broom 10 .

In 12 the third embodiment of the sweeping device 10 is shown in a side view. In the present case, one can see that at least one further height-adjustable skid 76 is arranged on the front of the housing 20 of the sweeping device 10, which is not identified in any more detail here. For example, two of these additional skids 76 can be provided on the front and rear. The skids 76 can be clamped by means of respective screws 78, which enables the skids 76 to be continuously adjusted. A desired height can thus be easily adjusted and the wear on the broom 14, more precisely on the bristles 26 of the broom 14, can be reduced. Alternatively or in addition to the screws 78, other adjusting and/or fastening means can also be provided in order to adjust the height of the skids 76. In other words, the skids 78 can be adjusted relative to the broom 14 in the vertical direction z.

The skids 76 can be made of bent spring steel, for example. A part of the skids 76 resting on the ground can run at least essentially parallel to the longitudinal direction x, wherein the part fixed by means of the respective screw 78 can run at least essentially parallel to the vertical direction z.
