Definitions

  • the invention relates to a hand-held roller spreader with a spreader container carried by two coaxial wheels, which has discharge openings on the bottom, over which a wheel-driven spreader roller rotates and a pivotable spreader rail is provided for adjusting the spreading quantity.
  • the spreading material is discharged in the spreading container by the rotating roller. Since the speed of the spreader roller depends on the wheel rotation, the spread rate per unit area is essentially independent of the driving speed of the device.
  • roller spreaders are manufactured in two versions:
  • the spreader roller is driven by both impellers in that the impellers are non-rotatably connected to the wheel axle carrying the hollow spreader roller.
  • the spreader roller is only driven via an impeller which is connected in a rotationally fixed manner to the wheel axle carrying the hollow spreader roller, while the other impeller is freely rotatable on the wheel axle.
  • the first embodiment has the advantage that when one wheel slips, the spreader roller is still driven by the second wheel, which ensures that the spreading material is evenly distributed when driving straight ahead.
  • cornering especially when turning the spreader when dispensing the grit in strips, a uniform discharge of the grit is no longer guaranteed because of the different curve radius, because one of the wheels must necessarily slide.
  • the device is lifted up and turned by 180 ° before turning.
  • the embodiment mentioned in the second place has the advantage that the device can also work when cornering, because only one wheel serves as a drive and the other wheel runs freely.
  • the disadvantage is that when the driving impeller slips, the spreader roller also stops and no uniform spreading material discharge is guaranteed.
  • the invention is therefore based on the object of a simply constructed, universally usable roller spreader to create, which combines the advantages of the above two embodiments.
  • the invention ensures that one and the same roller spreader can be used once with a single-wheel drive and once with a two-wheel drive, which eliminates the need for complex and expensive differential training.
  • the adjustment to the respective customer-specific request can be carried out by the seller, but also by the customer himself, so that the customer can make an adjustment to unicycle or two-wheel operation depending on the area to be sprinkled or depending on the weather conditions. It cannot then happen that the customer is annoyed afterwards that he has bought the gritter of the wrong type or of a type unsuitable for his specific circumstances.
  • the optional coupling of the impeller rotatably mounted on the wheel axle can be done by any means.
  • a plug-in coupling in the form of a plug-in bolt is preferred, which can be inserted into aligned holes of the wheel axle or hub of the impeller and which is preferably designed as a U-shaped bracket.
  • the spreader roller is connected to both impellers in terms of drive and acts in the sense of a differential lock, which has to be regarded as an advantage over the known freewheel arrangement designed as a differential, particularly in difficult terrain.
  • the spreading rail cooperating with the spreading roller can be adjusted from the guide bracket of the spreading carriage, the spreading quantity by presetting by means of a screw connection, which is provided with locking positions.
  • a spring returns the locking rail to the closed position, and the operator can move the spreading rail to the preset position using a switch bracket.
  • the spreading rail can then be moved into the closed position, for example, when turning, and after turning, the spreading rail can be brought back to the starting position.
  • FIG. 1 is an exploded perspective view of the individual parts which in their entirety form the roller spreader according to the invention
  • FIG. 2 shows a perspective partial view of the impeller which can be coupled in a rotationally fixed manner to the wheel axis;
  • Fig. 4 on a larger scale a section along the line IV-IV of FIG. 3;
  • FIG. 5 shows a view of the wheel axle rotated by 90 ° compared to FIG. 3.
  • the roller spreader has a spreader 10, which has two opposite openings 12 in the lower part for inserting the wheel axle 14 in the lower part.
  • This wheel axle carries the two-part, hollow litter roller 16.
  • This spreader roller 16 has at its two ends radial engagement slots 18 into which two inner embossments 20 of the wheel axle 14 engage and produce a rotationally fixed connection between the wheel axle 14 and the spreader roller 16.
  • the wheel axle 14 carries, via swivel arms 22, a spreading rail 24 which bears against the base part of the spreading container 10 and covers the spreading openings located there or releases them adjustable. By changing the Bowden access length 66 by means of the adjusting screw 68, the size of these discharge openings can be adjusted, which is activated by the diffusing rail 24.
  • the wheel axle 14 has on one side an external embossing 1530 which engages in a transverse slot 32 in the hub of the impeller 26, as a result of which the impeller is connected in a rotationally fixed manner to the wheel axle 14 or the spreader roller 16.
  • a securing element 34 in the form of a split pin is inserted into a radial hole 36 in the wheel axle 14 and secures the impeller 26.
  • Both impellers 26 and 28 carry a wheel cover 38.
  • the other impeller 28 can be freely rotated on the wheel axle 14 since the external embossing 30 is missing on this side of the wheel axle.
  • a radial hole 36 is also provided on this side, into which a locking pin 34 can be inserted.
  • the impeller 28 can optionally be coupled in a rotationally fixed manner to the wheel axle.
  • wheel axle 14 and wheel hub have two radial holes arranged at an axial distance from one another
  • a lower handle part 46 is inserted into bearing sleeves 48 of the rear container wall and secured by screws 50.
  • the rear angled ends of the lower handle part 46 can be provided with end plugs 52. These angled parts are used for support when not in use.
  • the upper handle part 58 is connected in the usual way via screws 54 with wing nut 56.
  • the spreading rail 24 carries a rear-facing extension 60, to which a fork-shaped clamp 62 is connected, to which a Bowden cable 66 engages via a calibration screw 64, which is connected to an adjusting screw 68 which is screwed into a threaded bushing 70.
  • This threaded bushing 70 is mounted in an offset 72 of a switching bracket 74, which is pivotably mounted in the upper handle part 58.
  • the set screw 68 carries an ergonomically designed wing 76, with which the set screw 68 can be screwed more or less deeply into the threaded bushing 70.
  • a locking arrangement is provided between the bushing 70 and the adjusting screw 68, so that a sensitive adjustment is facilitated.
  • a tension coil spring 78 engages on the side opposite the extension 60, which engages with the other end on the spreading container 10 and tries to pull the spreading rail into the closed position.
  • the spreading rail is transferred to the spreading position via the Bowden cable 66, the size of the released discharge openings having been set beforehand by the adjusting screw mechanism 68, 70.

Abstract

L'invention concerne un distributeur à rouleau comprenant un contenant distributeur porté par deux roues d'axe identique. L'axe de roues portant le rouleau distributeur creux est relié à une roue de façon bloquée en rotation. L'autre roue tourne librement autour de l'axe mais peut être fixée bloquée en rotation à l'axe par un organe de couplage. L'organe de couplage est, de préférence, un élément de serrage en U qui peut être inséré dans deux trous pratiqués dans le moyeu ou l'axe des roues à une certaine distance axiale. Ensuite, les trous sont amenés à être recouverts par rotation correspondante de cette roue. Cet élément de serrage peut ensuite être retiré de telle façon que le rouleau distributeur puisse être entraîné soit par une roue, soit par les deux. Le rail distributeur qui ferme plus ou moins les orifices de décharge, est précontraint dans sa position de fermeture par un ressort. Le rail distributeur peut tourner autour de l'axe des roues par un étrier monté pivotant sur l'élément supérieur de préhension à l'aide d'un câble de Bowden pour ouvrir les orifices de décharge. La quantité de distribution souhaitée peut être prélevée de façon sensible par un dispositif à vis de serrage.
