Definitions

  • the invention relates to a spreading disc for a winter service spreading device for spreading granulated spreading material, which is driven to rotate about an essentially vertical axis of rotation and is provided on its upper side with throwing vanes which run essentially radially to the axis of rotation and which have different radial lengths, and to which the spreading material is continuously fed from a storage container via a down pipe by means of a conveying device.
  • Spreading plates of the generic type are known (company lettering from Pietsch KG GmbH & Co), on the top of which are arranged sausage blades of different lengths, which run essentially radially to the axis of rotation of the spreading plate.
  • the spreading disc has a circular outer contour with which the outer ends close these sausage scoops flush. Due to the different lengths of the throwing blades, the inner ends lie on different radii.
  • six throwing blades are provided, which are all of different lengths from one another, the length of the longest sausage blades corresponding to approximately one third of the spreading disc radius and the length of the shortest sausage blade corresponding to approximately one fourth of the spreading disc radius.
  • a baffle is arranged centrally on the top of the spreading plate, which is covered on its periphery with a large number of sawtooth-like teeth, the radially outer tooth heads of which lie behind the radially inner tooth feet in the direction of rotation.
  • a radial distance is provided between the impact body and the sausage vanes, the size of which, depending on the length of the sausage vane, is between a third and about half the spreading disc radius.
  • grit from a granulate chute hits the impact body, which throws the granulate radially outwards onto the free top of the spreading disc between the impact body and the throwing blades.
  • the spreading material is there due to the low friction on the smooth surface of the spreading disc only decelerated greatly and therefore accelerated in an uncontrolled manner in the circumferential direction, as a result of which only a slight radial acceleration initially occurs.
  • the spreading material is caught in the radially outer areas by the throwing vanes and accelerated radially outwards. Because of the different lengths of the sausage vanes, different amounts of the spreading material are detected by them at different times and accelerated radially outwards towards the edge of the spreading plate and ejected radially there. Since the outer end edges of the differently long sausage vanes lie on the same radius, the spreading material is accelerated approximately to the same radial speed, so that the throwing distances of the differently long sausage vanes are approximately the same size.
  • the scatter density in the edge areas of the traffic area to be sprinkled, for example at the edges, is one Road, much denser than in the area immediately behind a spreading vehicle equipped with such a spreading disc.
  • the object of the invention is to improve a spreading disc of the generic type in such a way that, regardless of the speed-dependent spreading widths set in each case, a uniform distribution of the spreading material can be achieved over the entire spreading width.
  • the object is achieved according to the invention in that the radially inner ends of all throwing blades are on the same radius and the radially outer ends of the throwing blades are on different radii and that the outer edge of the spreading disc is flush with the outer ends of the individual throwing blades in the radial direction to the axis of rotation .
  • the embodiment of the invention according to claim 4 ensures that the spreading material reaches the impact surfaces of the central toothed cone as completely, directly and without interference as possible.
  • the configuration according to claim 5 ensures that the spreading material does not rise on the throwing blades and leaves them over the upper edge.
  • Fig. 1 shows a spreading plate 1, which is provided on its top with three groups of three, ie a total of nine evenly distributed in the circumferential direction sausage vanes 2, 3 and 4.
  • the spreading disc 1 is fastened by means of a hub 5 to an essentially vertical shaft 6 which can be driven to rotate about an axis of rotation 7.
  • a truncated cone-like toothed cone 8 is arranged coaxially to the axis of rotation 7 on the top of the spreader plate and is provided with eighteen sawtooth-like teeth 9 on its outer surface.
  • the spreading disc 1 has a flat circular section 10. The radius of the circular section 10 and the lower radius of the toothed cone 8 correspond to approximately one third of the maximum radius R1 of the spreading plate 1.
  • the ring zone of the spreading disc 1 lying radially outside between the toothed cone 8 and the outer edge 11 faces the horizontal plane 12, in which the circular section 10 of the spreading disc 1 is at a cone angle ⁇ of approximately 5 to 10 °, so that the outer edge 11 of the spreading plate 1 lies in the vertical direction above the circular section 10.
  • a liquid container 13 is arranged coaxially to the axis of rotation 7 and is provided with a liquid supply device 14.
  • a filler neck 15 is arranged on the side of the liquid container 13 diametrically opposite the liquid supply device 14.
  • the teeth 9 of the tooth cone 8 are arranged in such a way that their tooth heads 16 lie in front of the respective tooth feet 18 in the direction of rotation of the arrow 17.
  • the tooth flanks 19 lying forward in the direction of rotation of the arrow 17 serve as baffle surfaces for the scattering material hitting the tooth cone 8.
  • the radially inner ends of the throwing blades 2, 3, 4 end on a radius R which is smaller than the radius of the toothed cone 8 or of the circular section 10.
  • the throwing blades 2, 3, 4 each adjoin one of the tooth flanks 19 of the toothed cone without gaps 8 on and run in the direction of the tooth flanks 19.
  • the tooth flanks 19 of the tooth cone 8 thus form with the throwing blades 2, 3, 4 a closed radial guide surface 20 for the grit.
  • the throwing blades 2, 3, 4 have different lengths 12 , 13 , 14 , so that their radially outer ends 2/1, 3/1, 4/1 lie on different radii R2 , R3 , R4 with respect to the axis of rotation 7.
  • the throwing blades 2, 3, 4 are arranged one behind the other in such a way that, in the direction of rotation of the arrow 17, a throwing blade 3 with an average length 13 follows a longest throwing blade 2 and a sausage blade 4 with the shortest length 14 follows this.
  • the peripheral outer edge 11 of the spreader plate 1 is adapted to the different lengths of the throwing blades 2, 3, 4 so that they are in the radial direction with the outer end edges 2/1, 3/1 and 4/1 of the throwing blades 2, 3 and 4, respectively ends flush.
  • the circumferential sections 21, 22 and 23 of the spreading disc 1 lying between the outer end edges 2/1, 3/1, 4/1 of the individual throwing blades 2, 3, 4 run in an arc shape and continuously merge into one another.
  • peripheral sections 21, 22, 23 can also connect the outer ends 2/1, 3/1, 4/1 to one another in the form of a straight line 24 or a concave arc 25 or a convex arc 26.
  • the throwing vanes 2, 3, 4 have a cross-sectional profile that extends over approximately two thirds of their total height from the top of the spreader plate, essentially axially parallel to the axis of rotation 7, i.e. runs essentially in the vertical direction upwards and is bent forward in a quarter circle in the upper third in the direction of rotation of the arrow 17.
  • the outer end edges 2/1, 3/1, 4/1 run from bottom to top axially parallel to the axis of rotation 7 or at right angles to the surface of the spreader plate. However, this course of the end edges 2/1, 3/1, 4/1 influences the scatter pattern only to a negligible extent.
  • each throwing blade 2, 3, 4 end with their radially outer ends 2/1, 3/1, 4/1 on different radii, it is achieved that each throwing blade 2, 3, 4 with respect to the throwing direction and the throwing distance a different spread pattern, ie a different spread fan (FIG. 4).
  • the spreading material striking the toothed cone 8 bounces from the tooth flanks 19 of the teeth 9 of the toothed cone 8 onto the surface of the spreading plate 1.
  • the throwing blades 2, 3, 4 are in the area of their connection with the Tooth flanks 19 are provided with recesses 2/2, 3/2, 4/2 on their upper edge.
  • the spreading material that leaves the spreading disc over a larger radius is not only accelerated over a longer period of time, but it is also additionally accelerated accelerated with an increasing radial force outside.
  • the radial speed is the lowest on a short throwing blade 4 and the radial speed on the longest throwing blade 2 is greatest, so that different throwing distances are achieved.
  • the throwing direction and the throwing angle are also of the individual throwing blades 2, 3, 4 differently, because, as I said, the spreading material leaves the spreading disc earlier in the short worm blades 4 than in the longer spreading blades 3 or 2, the spreading material compartments of which begin in a later angle of rotation position.
  • the overlapping of the spreading patterns or spreading material compartments 28, 29 and 30 generated in this way during driving results in an at least almost uniform distribution of spreading material on the road.
