Definitions

  • the invention relates to a spreader for road service, the silo structure for the spreading material is built on the loading platform of a work vehicle, the hydraulic and electrical units required for conveying the spreading material are arranged in their entirety on the back of the silo structure, where they are inside an in essentially closed rear box are housed.
  • US-A-3,599,894 describes such a spreader.
  • the present invention has for its object, while avoiding the disadvantages mentioned, to create a silo spreader in which the associated hydraulic and electrical Units are not only clearly arranged and easily accessible for the specialist, they are also removed from unauthorized use and, moreover, are less exposed to attack by dirt and icing.
  • This object is achieved according to the proposal of the present invention on a generic spreader in that the units are accessible through a closable opening of the rear box, that the rear box extends substantially over the entire surface of the silo rear wall and is aerodynamically shaped by being flush with closes the side walls of the silo structure, and that the opening of the rear box is designed as an upward-pivoting tailgate, the pivot axis of which is arranged higher than man-height.
  • Tailgate is a roof for the operator, so forms a bad weather protection.
  • a particularly advantageous embodiment of the rear box consists in that it has a roof that rises obliquely towards the rear wall of the silo, the lower edge of which merges into the outer wall of the rear box with a curve.
  • Such a streamlined design of the rear box generates a largely vortex-free flow at the rear of the vehicle, through which the pollution of the rear of the vehicle is significantly reduced.
  • the shape of the tailgate that the tailgate is sunk in its outer wall, so that the tailgate has a closed surface.
  • the rear box has a cutout on the underside for the exit of the grit conveying channel from the silo, i.e. the rear box is pulled down further on both sides of the grit conveying channel.
  • the proposal according to the invention also achieves a better weight distribution on the two axles of the work vehicle, the front axle of which is usually particularly stressed by a snow plow;
  • the arrangement of the above-mentioned units on the rear wall of the silo structure relieves the load on the front axle, which has a particularly favorable effect when the silo container is empty.
  • Fig. 1 shows a so-called silo spreader in the rear view.
  • the silo structure 1 is arranged on the loading platform 2 of a work vehicle.
  • a grit conveying channel 3 emerges from the underside of the silo structure 1, the outlet opening 4 of which opens out via a chute 5 which directs the grit onto the top of a rotatable spreading plate 6.
  • the quantity of spreading material supplied to the spreading plate 6 some additional units are required, all of which are mounted on the rear wall 7 of the silo structure 1 and are covered there by a rear box 8.
  • the rear box 8 extends over the entire width of the silo rear wall 7; it has a roof 9 which rises obliquely towards the silo rear wall 7 and which merges with a curve 10 into the rear outer wall 11 of the rear box 8.
  • a tailgate 12 is arranged sunk, which around her horizontal upper edge 13 can be folded up.
  • the tailgate 12 is closed. It is shown with dashed lines 14 in the folded-up, that is, open position.
  • block 15 denotes the hydraulic tank with filter and accessories
  • block 16 the complete hydraulic control
  • block 17 the electrical distribution box
  • block 18 the dampening salt pump with accessories.
  • a lock 19 for closing the tailgate is shown at the bottom right.
  • the rear box 8 In the area of the grit conveyor channel 3, the rear box 8 has a cutout 20, i.e. the rear box 8 is pulled further down on both sides of the grit conveying channel 3.
