Definitions

  • the invention relates to a winter service spreader for mounting on a vehicle; it also relates to a spreading material container for such a spreading device for receiving granular spreading material.
  • Known spreading devices usually have a steel V-shaped spreading material container, in the bottom area of which a conveying device running in the longitudinal direction of the spreading container, preferably in the form of a screw or belt conveyor, is arranged. By means of this conveying device, the spreading material is fed to a spreading material distributor which is arranged at the rear end of the spreading container on the outside thereof.
  • the spreading material container is either attached to the loading platform of a vehicle or directly on the vehicle chassis, it being possible for the vehicle to be designed as a trailer or self-propelled.
  • the present invention proposes a solution which avoids the disadvantages mentioned; it is characterized by the following features:
  • the bottom assembly comprises a belt or screw conveyor device conveying in the longitudinal direction of the container to a litter distributor;
  • the floor assembly further comprises a floor frame on which the container is supported;
  • the container is composed of individual prefabricated wall elements.
  • Element construction also opens up the possibility of using materials other than steel.
  • the container size can advantageously be adapted to an existing vehicle chassis, so that special constructions are unnecessary.
  • the container wall elements can be manufactured in stock and thus enable flexible adaptation to requirements with simple and quick production.
  • the container comprises, in addition to a front wall and a rear wall, an even number of mutually identical change elements, i.e. each side wall of the container consists of one or more side wall elements which are lined up in the longitudinal direction of the container.
  • a single mold or device is sufficient to produce the side wall elements.
  • a belt conveyor device there is also the possibility of designing the front wall and the rear wall with one another in the same way, in that both walls each have an opening for the belt conveyor device which is extended beyond the container at the front and rear.
  • the bearing blocks for the belt conveyor are in this case outside of the container
  • the corrosion problems outlined above can be avoided in that the wall elements are made of plastic or as composite elements made of plastic and steel, preferably as hollow bodies, these being completely or partially filled by a rigid foam structure can be.
  • Particularly suitable materials are polyethylene or polypropylene; It is also favorable to manufacture the hollow bodies by centrifugal casting, e.g. made of polyurethane.
  • the side wall elements provide that they have flanges on the end face, in each of which connection means to an adjacent wall element are accommodated.
  • the wall elements are preferably screwed together, and elastic inserts can be provided in the connecting surface for the purpose of sealing and tolerance compensation.
  • the side wall elements can tanks can be widened without increasing the overall width of the spreading material container.
  • Such liquid tanks are required as brine stores for damp salt spreading, each tank being connected to the spreading material distributor via a brine line. Brine and granular spreading material are spread over the spreading material distributor.
  • each liquid tank formed by a side wall has an upper filler neck and a lower drain neck.
  • the side wall elements each have a shape toward the outside in their lower wheel area, the horizontal section of which overlaps the side edge of the conveyor belt and the vertical section of which is fastened to the floor frame.
  • the floor frame expediently consists of longitudinal and transverse bars, the distances between adjacent transverse bars each corresponding to the length of a side wall element.
  • the wall elements can be connected in the region of their upper edge by means of rod-like or rope-like tensioning elements; this enables material savings, particularly in the manufacture of the wall elements Plastic.
  • a suitable tensioning element can be, for example, a rope running around the upper edge, on which all wall elements are threaded; cross-ropes and longitudinally tensioned ropes or tension rods are also possible.
  • the modular structure of the scattering material container according to the invention results in considerable savings in its manufacture, in particular if the same shape is used for all side wall elements made of plastic and if this also applies to the front wall and the rear wall, so that in total only two shapes required are. In the event of damage to a wall element, it can be replaced by a new one, while the rest of the container can still be used.
  • the plastic litter container according to the invention only weighs about half.
  • a further advantage in favor of the use of plastic wall elements is better thermal insulation, as a result of which the spreading material has good pourability even at very low outside temperatures.
  • FIG. 1 shows a perspective illustration of the spreading device
  • FIG. 2 shows a vertical cross section of the spreading device according to FIG. 1 in the region of a side wall element
  • FIG. 3 shows a vertical cross section through an alternative

  • a drive unit 5 for the conveying device 3 is flanged on the left side of the spreading material distributor 4. The spreader is moved in the direction of the arrow F
  • the bottom frame 2 consists of two U-shaped longitudinal bars 7, between which the transport rollers of the conveying device 3 are mounted.
  • the two longitudinal bars 7 are supported on box-shaped cross bars 8; the latter are attached to a vehicle chassis, not shown.
  • the scattering material container 1 is composed of individual wall elements, namely a front wall 9 and a rear wall 10 and side wall elements 11 that are identical to one another, three of them on each side.
  • the side wall elements 11 have, on their end faces, outwardly projecting flanges 12, in the area of which are indicated screw connections 13 indicated by points.
  • the rear wall 10 and the front wall 9 each have an opening 33 for the passage of the belt conveyor 3, the opening in the rear wall 10 being closed by a slide 14 which can be actuated by means of an actuating rod 15.
  • Retention plates 16 for the road salt can be inserted into corresponding recesses on the inside of the side wall elements 11 to control the salt flow.
  • tensioning elements are indicated, which are ropes or tension rods
  • a cross-sectional view according to FIG. 2 shows a side wall element 11 designed as a hollow plastic body. It has an approximately constant wall thickness, and the cavity between an inner wall part 18 and an outer wall part 19 can be stiffened with foamed plastic.
  • the inner wall part 18 extends to just above the surface of the conveyor belt 6, which runs on transport rollers 20.
  • the gap between the inner lower edge of the inner wall part 1 and the surface of the conveyor belt 6 is bridged by a sealing rail 21, preferably made of rubber, which is continuous in the longitudinal direction of the container 1.
  • the sealing rail 21 is screwed to the inner wall part 18 at 22.
  • the side wall element 11 forms a shape, the horizontal section 23 of which overlaps the side edge of the conveyor belt 6 and the longitudinal spar 7.
  • the shafts 24 of the transport rollers 20 are mounted in bearings 25 in the longitudinal spar 7.

  • FIG. 3 shows in cross section a variant of a side wall element, in which an enlarged cavity is formed between the inner wall part 18 and the outer wall part 19, which serves as a liquid tank for holding a salt solution for damp salt scattering.
  • a nose 31 is formed at the upper end of the inner wall part 18 and has an opening 32 for fastening a tensioning element 17.
