Definitions

  • the invention relates to a spreading device according to the preamble of claim 1.
  • Spreading devices are known in which a funnel-shaped spreading material container is placed on the loading area, from which the spreading material is fed to the spreading material dispensing device, in particular to a spreading material plate, via a spreading material conveying device.
  • container spreader devices of the generic type are known in which the generally funnel-shaped grit container is attached to the carrier vehicle at the rear end of the loading area and the grit container is filled batchwise by tilting the loading area of the carrier vehicle to the rear.
  • Known grit containers of this type are independent containers which are independent of the loading area of the gritting vehicle and have the disadvantage that it is necessary to completely empty the container to guide the entire grit in the grit container over the grit discharge, which requires considerable time because with conventional spreading devices the construction takes up the entire loading area and the assembly and disassembly is time-consuming. If the loading area is quickly required for other purposes, this leads to the vehicle not being ready for these other purposes.
  • a gritting vehicle of the generic type in which the loading area with side walls can be tilted sideways and the grit is fed to the grit spreading device by means of a screw conveyor operating in the vehicle's longitudinal axis, which is in the immediate vicinity of a side gantry of the gritting vehicle and the ground the loading area is arranged.
  • US-A-47 73 598 relates to a spreading vehicle with a tilting device for the loading area, which enables the spreading material to be tilted backwards and to the side from the loading area.
  • the object of the invention is to provide a spreading device with a conventional spreading material dispensing device, e.g. To design the spreading disc arrangement so that emptying of the spreading material container is practically possible without a time delay, regardless of the degree of filling, and at the same time the functionality of the spreading device is not influenced. Furthermore, the holding capacity of the spreading material in the spreading device should be as large as possible and at the same time the center of gravity of the filled spreading material container should be as low as possible. Furthermore, the use of a double grit container should be provided in a simple and economical manner.
  • the spreading material is loaded on the entire loading area and is brought in a simple manner with the least technical effort directly from the loading area of the vehicle by means of a screw conveyor or the like to the rear to the spreading material spreading device (spreading plate) and thus an extremely large loading volume over long spreading distances can be carried.
  • the unused grit can be tipped backwards or sideways regardless of the filling level of the grit chamber practically, quickly and easily without significant time delay, so that the grit container or the loading area can be completely emptied in a very short time without the grit first having to pass through the grit spreading device , which would take a considerable amount of time and without the need to dismantle a grit container.
  • the loading area is possible thanks to the extremely fast emptying of the spreading material chamber Can be released very quickly and the vehicle can be used for other purposes within a very short time. Furthermore, due to the opening of the grit container to one of its sides, an integration of grit container into the loading area results in that a separate and independent grit container, as is required in conventional devices, is no longer required, and thus the focus of the entire spreading device can be laid extremely low with grit, which is essential for the driving behavior of the carrier vehicle, especially in winter operation, since when starting off, braking and cornering, there is no or only negligible tendency to tip backwards, forwards or to the side.
  • the spreading device is attached on one side of the loading area to one side wall (either the right or the left) assigned.
  • the grit container can either take up a fraction of the width or the entire width of the loading area; in the latter case, the opposite side wall of the loading area is the other side wall for the spreading material.
  • the spreading device is provided with an intermediate wall which runs parallel to the side wall of the loading area and which faces the inside of the loading area, so that the grit container is formed between these two side walls and occupies an adjustable part of the loading area width.
  • This partition can be firmly connected to the bottom of the grit container, but it can also be slidably formed on the floor of the loading area in the manner of a drawer, so that with the change in the width of the grit container in reverse proportion the width of the remaining part of the loading area also varies can be.
  • Such tipping of the material can also be done by tilting the loading area to the rear if the replacement side wall connected to the rear of the grit container and closing off the remaining part of the loading area is removed.
  • the grit container itself is designed so that its side wall has a wall part which is pivotally attached directly to the bottom of the grit container or to the bottom wall of the loading area, and which is open, e.g. can be folded down so that the material can be discharged from the grit container when the drop side is folded down if the loading area is tilted accordingly about its central longitudinal axis.
  • a complete emptying of the grit container is then possible in the shortest possible time without the grit having to pass through the grit dispensing device.
  • Such emptying of the spreading material container is necessary if the spreading device is to be removed from the loading area, or if the loading area or the carrier vehicle is required for other purposes.
  • a double container spreading device on the loading surface, namely two spreading devices arranged next to one another.
  • the two grit containers are placed side by side, the open side of the left container being delimited by the side wall of the right container and the right container by the right side wall of the loading area, or vice versa.
  • one container generally holds road salt and the other container split, sand or the like, the split container usually being substantially larger in volume than the salt container.
  • both chambers have separate screw conveyors, but preferably have a common spreading disc instead of two independent spreading discs, with a slide, chute or each then away from the outlet openings of the two spreading material containers the like.
  • This material pick-up device is designed so that a tilting of the loading area with the two spreading material containers does not affect the functioning, for this purpose the slide or bulk parts can be displaced relative to one another, for example they can be telescopic, in order to compensate for the different altitudes when tipping. Instead, however, one or both containers can also each have a belt conveyor device for delivering material to the spreading plate.
  • the spreading material dispensing device or the spreading plate is fastened to the rear wall of the spreading material device or to the floor or frame of the loading area.
  • the arrangement is chosen so that the connection to the holder of the spreading plate is designed to be pivotable, such that when the loading surface tilts the shaft and spreading plate maintain their working position, namely the fixed assignment to the vehicle frame or level of the spreading plate parallel to the ground.
  • This requires a corresponding guidance of the spreading plate shaft relative to the loading area or an articulated suspension of the spreading plate on the loading area and at the same time a firm connection of the spreading plate screen to the vehicle frame.
  • the spreader plate is attached to the stationary frame of the vehicle in such a way that it retains its position unchanged regardless of the pivoting or tilting of the loading area.
  • the spreading plate is attached with its holder to the stationary frame of the vehicle so that it can be easily solved, for. B. via a plug connection with locking.
  • the spreading device with spreading disc is only required during the winter months, in the rest of the year the entire spreading device with spreading disc is removed from the vehicle and stored.
  • a known, running on wheels transport frame is used, which engages at least two locations on the spreader and the spreader, which by quick-release with the Vehicle frame or the loading area is connected, lifts and removed from the vehicle.
  • the spreader plate is preferably designed such that it can be folded upwards or can be detached from the spreader in a simple manner.
  • the arrangement is chosen such that the shaft with the spreading plate is pivoted up about the pivot point G in a plane parallel to the plane of the rear wall, so that in this case the spreading device does not have to be dismantled.
  • a funnel-shaped outlet opening on the rear side of the tailgate which can be closed by hand or by remote control and which is suitable for the targeted delivery of material, e.g. for depositing split in smaller, portioned piles, e.g. also for filling grit boxes on the roadside.
  • FIG. 1 designates a tiltable loading area of a carrier vehicle (not shown) which is fastened with a tilting frame 2.
  • the floor of the loading area is 3, the side walls 4 and 5.
  • the front side wall 6 facing the driver's cab connects the two side side walls 4 and 5; the tailgate is removed.
  • the spreader consists of the spreader 9, the spreader 18 and the spreader 21 with spreader 22.
  • the spreader is a box-shaped, open top container with an angled side wall 10, 11, 12, a bottom wall 13, one of the container wall 10, 11, 12th opposite side wall 14 which the Side wall 5 can be, a front end wall 15 and a rear end wall 16.
  • the side wall 14 defines the volume of the grit container 9 within the loading volume of the loading area.
  • the rear of the loading area 3, 4, 5 is extended in the plane of the rear wall 16 of the grit container by a wall section 17 from the rear wall 16 to the side wall 5, so that the two walls 16 and 17 completely close off the loading area to the rear.
  • the wall section 17 (replacement rear wall) is detachably connected to the rear wall 16 of the grit container and to the side wall 5.
  • a grit conveying device 18 in the form of a screw conveyor is arranged within the grit container 9, the axial direction and conveying direction of which run parallel to the central longitudinal axis L of the loading area.
  • the screw conveyor 18 conveys the grit in the grit container 9 backwards to the grit outlet 19 assigned to the auger, which is followed by a slide, chute or the like 20, which delivers the grit to the grit dispenser 21, which from the rotating gritter plate 22, the Holding device 23, which is fastened, for example, to the rear wall 16 or to the loading area 1, and has a grit holder 24, into which the grit is received from the chute 20 and delivered directly to the grit plate 22.
  • a lifting device which is preferably a lifting cylinder, the lifting arm 26 of which is connected to the frame 2 of the loading area 1 at its central longitudinal axis L, and which is supported on the vehicle frame.
  • the lifting cylinder 25 By extending and retracting the lifting cylinder 25, the loading area is tilted about the tilting axis L 'or L'', so that the loading area can be emptied either to the left or to the right.
  • the left tipping point L '' is locked
  • the right tipping point L ' is locked.
  • the loading area 3 can optionally also be tilted backwards (about the transverse axis QQ), so that the loading area can also be emptied via the rear side if the rear walls 16 and 17 are removed.
  • FIG. 3 The tilting of the loading area to the left is shown schematically in FIG. 3. This tipping process is carried out when the loading area is completely emptied or, in order for the spreading material to be continuously discharged from the grit container, grit material has to be replenished batchwise from the loading area into the grit container. So that the spreading plate maintains its vertical position, its holder is articulated to the rear wall of the spreading material container or to the loading area at G (indicated in FIG.
  • the spreading plate screen 22 ′ is fixed to the vehicle frame via a holding rod 28 or the like (schematically indicated with 29) so that the entire spreading material dispensing device 21 (with spreading plate 22, holding device 23 and spreading material receptacle 24) maintains its position relative to the vehicle frame and can compensate for the tilting movement of the loading area 1.
  • the spreading plate 22 always spreads spreading material in a constant plane parallel to the ground plane, regardless of the inclination of the loading area.
  • the spreading part 21 - 24 is indicated by dashed lines.
  • the holding rod 28 is released from the spreading plate 22 'and in the folded-up position the shaft 23 or the spreading plate 22 is locked.
  • the holder 23 is not articulated to the loading surface or the rear wall of the spreading material container 9, but is firmly connected to the vehicle frame, for example plugged onto the vehicle frame 29 and locked by a lock, so that when it is removed the gritting device from the loading area 1, the gritting device 21 is only detached from the frame and, since all other connections, for example electrical and hydraulic connections to the spreader plate are firmly connected to the other gritting device, the gritting device is retained as a whole unit.
  • the spreading material plate and the spreading material receiving device can be designed in all embodiments of the invention in such a way that they can be pivoted upwards, which means that none for storing the spreading material device there are more parts protruding downward beyond the bottom of the device, especially since the slide or chute 20 can also be designed to be removable.
