Definitions

  • the invention relates to a device for dispensing grit a grit container with a grit discharge opening and a grit conveyor in the form of a conveyor belt on which one from the container through the The discharge opening of the spreading carpet that has been discharged into a spreading material distributor is fed.
  • the aforementioned spreading devices are used, for example Winter service vehicles for spreading salt.
  • the grit container has typically a conical, funnel-like cross-section, for which reason the Conveyor belt lies.
  • the conveyor belt moves below that in the Grit container located opposite the direction of travel of the Winter service vehicle, pulls salt from under the salt dome and promotes you Salt carpet through the grit discharge opening to the grit distributor, usually a centrifugal disc or a so-called spreading disc.
  • the height and width of the salt carpet created on the conveyor belt is determined by the Opening cross-section of the grit discharge opening determined.
  • the desired The spread rate per lane area is given a given opening cross-section depending on the driving speed by adjusting the Conveyor belt speed metered.
  • Difficulty is the processing of grit, which tends to stick, for example evaporated salt. If very fine evaporated salt is a moisture of over has a weight percent, it begins to stick together very strongly. This effect increases at temperatures below -3 ° C. The one on the The conveyor belt transported by the spreading material carpet then forms a salt cake breaks off like a briquette from the conveyor end of the conveyor belt and into the spreading hopper falls. Through this lump-wise breaking off a very then arises uneven, pulsating scatter pattern with places particularly high Concentration and other places where there is no salt on the road at all is distributed. This problem is at low vehicle speeds of 5 km / h and particularly pronounced below. It can take several seconds in which no salt falls on the spreading disc.
  • the object of the present invention is therefore to find a solution to the problem to propose, like evaporated salt, which tends to stick, even at low levels Conveyor belt speeds can be reliably carried out.
  • a conveyor belt shredder is provided on the conveyor belt.
  • This is what it is about preferably a crushing roller, which is particularly effective when it is located directly at the end of the conveyor belt, because there it can rest on a pulley of the conveyor belt.
  • the pulley can do that be such or that between the pulley and the Crushing roller lying material of the conveyor belt.
  • the Shredding roller can be designed so that it without any special effort Forcibly conveyed runs on the belt or the pulley.
  • one Forced support can of course also be an external drive for the Crushing roller be useful.
  • a preferred embodiment of the comminution roller has in it Crushing rods lying on the lateral surface, which rotate when the Dig the crushing roller into the spreading carpet and break it open.
  • the shredding bars in the keep the spreading carpet as low as possible Shell surface preferably arranged helically. So only ever acts short section of the shredding rod onto the carpet of spreading material. Thereby it is possible to make the shredding rods comparatively narrow with one Correspondingly favorable cutting effect on the grit to be shredded train.
  • Figure 1 shows schematically in side view, representative of many types of carrier vehicles and their superstructures, a winter service spreading vehicle with a loading area 2, on which a grit container 1 rests.
  • the grit container 1 is in Figure 2 shown again in plan view. It can also be used as a trailer or as a fixed one Body mounted on a chassis.
  • the side walls 9 of the container 1 converge towards the bottom of the container, on which a conveyor belt 4 is located.
  • the conveyor belt 4 runs in the transport direction (arrow direction) under one in the salt dome located in container 1 and thereby draws off salt.
  • the salt will conveyed out of the container 1 through a grit discharge opening 3, wherein there is a spreading material carpet 11 on the conveyor belt 4 outside the container 1 trains (Figure 3).
  • the height and width of the scatter carpet 11 is determined through the opening cross section of the discharge opening 3, the height of which in turn is manually adjustable by a vertically displaceable slide 13.
  • the pro The amount of salt extracted is determined by the transport speed of the Conveyor belt 4 defined. For a given spread rate per lane area hangs the transport speed of the conveyor belt 4 from the width of the to be spread Area on the one hand and the vehicle speed on the other.
  • the spreading material conveyed by the conveyor belt 4 falls from the end of the conveyor belt 4 into a funnel 8 and from there to a spreading material distributor 7 in the form of a Centrifugal disc or a spreading disc.
  • a grit carpet shredder 5 in the manner of a shredding roller, in order to break up any lumped material before it enters the hopper 8 falls down.
  • the crushing roller 5 lies with its axis of rotation perpendicular above and parallel to the axis of rotation of the deflection roller 12 of the conveyor belt 4 and is against the Deflection roller 12 or the intermediate conveyor belt 4 pressed so that the roller 5 is forcibly conveyed from the conveyor belt 4.
  • the Shredding roller 5 two impellers 10, between which the scattering carpet 11 passes through, and crushing rods 6, which between the impellers 10 lie helically in the imaginary surface of the roller 5.
  • the roller 5 is basically hollow with a central axis of rotation to stabilize the Crushing drum. This arrangement ensures an even breakup of the scattering carpet 11 reached.
  • the shredding rods 6 arranged in a helical manner do not have to necessarily all have the same direction of rotation. On the contrary, it is advantageous for a uniform breakup of the scattering carpet 11, if individual shredding rods 6 in their screw-shaped direction of rotation differ.
  • a preferred embodiment shown in FIG. 4 sees before that the shredding rods 6 are not over the entire length of the Crushing roller 5 extend, but for example only from each side of the Shredding roller 5 up to its center. In the middle and / or elsewhere the shredding roller 5 can also further wheels 11 or Stabilizing disks 14 for stabilizing the shredding rods 6 be provided.
  • the shredding rods 6 can have a wide variety of cross sections. she can, for example, from round bars or, as in Fig. 4, from flat steel be produced, in the latter case the narrow side of the flat steel preferably pointing radially away from the axis of rotation of the comminution roller 5, so that the shredding rods 6 in the scattering carpet 11 from above cut into it.
  • FIG. 5 shows the comminution roller 5 from FIG. 4 with a fastening plate 15 to fix the roller 5 on the turntable suspension and with one over the entire width of the roller 5 extending stripper 16, the sticky, shredded mass from the belt, otherwise a considerable part of road salt on the conveyor belt.
  • the constancy of the spread pattern can thus be significantly improved.
