Definitions

  • the present invention relates to a spreader, in particular for winter service vehicles, for dispensing of scattering material, comprising a scattering container, a discharge unit and arranged between the scattering container and the dispensing unit scattering material conveying path, wherein the dispensing unit has a rotating spreading plate and a central mixing chamber, in which the Scattering conveyor line opens and which comprises a rotating mixing tray and a non-rotating boundary with a around the axis of rotation of the mixing tray around extending, having an outlet opening side wall and an upper end part.
  • Such a spreader is from the WO 2005/033417 A1 known.
  • a liquid conveying path opens into the mixing chamber, so that the - initially dry - scattering substance in the mixing chamber is intensively moistened before the correspondingly moistened scattering material leaves the mixing chamber through the outlet opening and reaches the spreading plate be applied by this on the road to be sprinkled.
  • the upper end part of the mixing chamber has an opening through which the scattering material enters the mixing chamber.
  • Another spreading chamber having a central mixing chamber for spreading material is known from EP 1942230 A1 known.
  • the present invention is directed to provide a spreader of the generic type, which is characterized by an improved characteristic of the scattering distribution.
  • the upper end part of the mixing chamber at least adjacent to the side wall its height above the mixing tray in the circumferential direction.
  • the upper end part of the mixing chamber provided in the spreader according to the invention is not a flat component extending parallel to the mixing bottom. Rather, at least adjacent to the side wall of the mixing chamber whose upper end part in the circumferential direction is arranged in regions higher above the mixing bottom than in other areas.
  • the height of the upper end part of the mixing chamber in the direction of rotation of the mixing tray in front of the outlet opening steadily decreases over an angular range, wherein the range of decreasing height of the upper end part is preferred to short or possibly even immediately before Outlet opening extends.
  • the scattering current over the said angular range is compressed or bundled comparatively uniformly in terms of its extent in height, so that discontinuity effects that would be associated with a loss of reproducibility can be largely avoided.
  • a more or less flat scattering material jet leaves the mixing chamber through its window-like outlet opening, depending on the current spreading material throughput through the application unit, and arrives at the spreading plate, where it is detected by the throwing blades typically provided there.
  • the angle range, beyond the height of the upper End part of the mixing chamber decreases steadily in the above-mentioned sense, is advantageously at least as large, more preferably at least about twice as large as the extension of the outlet opening in the circumferential direction.
  • the said angle range is approximately between 80 ° and 160 °, particularly preferably between 90 ° and 150 °.
  • the maximum height of the upper end part above the mixed bottom is at least 50%, more preferably at least about 80% or even 100% greater than the lowest height of the upper end part above the mixed bottom; or in other words, the minimum height of the upper end part above the mixed bottom is preferably at most 65%, more preferably at most about 55% or even only 50% of the highest height of the upper end part above the mixed bottom.
  • a height of the side wall of the mixing chamber in particular sufficient for intimate mixing of dry spreading material with liquid, against which the scattering material is thrown through the rotating mixing floor, is available, with the above-described compaction on the other side the scattering jet is caused in height before leaving the mixing chamber.
  • the height of the outlet opening is a maximum of 50% of the maximum height of the upper Final parts of the mixing chamber above the mixed bottom is.
  • the smallest height of the upper end part of the mixing chamber above the mixing bottom is at most insignificant (for example at most 10%) greater than the maximum height of the edge which delimits the outlet opening above the mixed bottom.
  • Another turn, with which the scattering result can be positively influenced, consists in a preferred embodiment of the present invention is that the height of the outlet opening above the mixing tray over an angular range in the direction of rotation of the mixing tray increases, ie the outlet opening after above limiting edge increases over an angular range.
  • the circumferential direction of the scattering material along the side wall of the mixing chamber thus reaches scattering - at a low level to the mixed soil - seen earlier in the circumferential direction earlier through the outlet opening through the scattering plate as a scattering material, which migrates at a greater height to the mixing tray on the side wall of the mixing chamber.
  • the risk of irregularities in the scattering pattern is significantly reduced, especially at high scattering substance throughputs by the application unit.
  • the side wall of the mixing chamber of the spreader according to the invention has, according to yet another preferred development, a substantially cylindrical basic shape, so that the generatrices of the side wall preferably extend parallel to the axis of rotation of the mixing bottom.
  • the side wall of the mixing chamber in this case have a substantially circular cylindrical basic shape, ie lie on the surface of a circular cylinder, which of course does not exclude a slight superimposed profiling (eg corrugation), by which mixing effects can be favored.
  • the substantially circular-cylindrical basic shape of the side wall of the mixing chamber is also favorable with regard to the possibility to influence specifically by defined rotation of the boundary of the mixing chamber about its axis, which preferably coincides with the axis of rotation of the spreading plate Scatter image, ie the position of the streaked strip relative to the vehicle (centered or symmetrical or more or less pronounced asymmetrically shifted to the left or right).
  • the boundary of the mixing chamber can be rotated (see below) in order to be able to change the angular position of the ejection opening relative to the spreading vehicle
  • the opening provided above in the boundary of the mixing chamber, through which scattering material is supplied to the mixing chamber typically extends over one larger angle range, to avoid that the mouth of the scattering material conveyor line (eg a chute) must be rotated together with the mixing chamber to adjust the scattering pattern.
  • the radial extent of the upper end part in that region, in it changes its height to the mixed soil is at least 15% of the radius' of the cylindrical basic shape of the side wall.
  • a larger radial extension is quite possible, although it should be noted that typically a sufficiently large sized breakthrough in the upper end part is to be provided, through which scattering material passes from the scattering material conveying path into the mixing chamber.
  • a liquid conveying path opens, through which liquid is fed into the mixing chamber, which serves to moisten the initially dry scattering substance.
  • a liquid conveying path opens in the direction of rotation of the mixing bottom less than 180 ° behind the mouth of the scattering material conveying path.
  • a relatively small angular offset between the mouth of the scattering material conveying path and the mouth of the liquid conveying path is particularly favorable, so that a particularly effective mixing of scattering material and liquid takes place within the mixing chamber before reaching the outlet opening.
  • the upper end part of the mixing chamber extends in regions, preferably at least in the direction of rotation of the mixing bottom immediately behind the mouth of the liquid conveying path into the mixing chamber from the side wall substantially to the axis of rotation or hub of the mixing bottom.
  • the mixing chamber is thus essentially closed towards the top.
  • the upper end part of the mixing chamber is suitable in a preferred embodiment of the invention also to fix the mouth part of the liquid conveying path.
  • the mouth of the scattering material conveyor line changes when the boundary of the mixing chamber - to change the scattering pattern - rotatable, the mouth of the scattering material conveyor line is stationary (see above), the angular offset between the mouth of the scattering conveyor line and the mouth of the liquid conveyor line in dependence the set position of the scattering pattern; it is preferably between about 45 ° and 155 °, depending on the spreading pattern.
  • the mixed bottom passes radially inward into a substantially frusto-conical core.
  • This too may favor an effective mixing of the scattering substance and the liquid in the mixing chamber, in particular if a partial flow of the liquid is directed onto the frustoconical core.
  • the liquid stream introduced into the mixing chamber through the liquid conveying path is divided into two partial streams in the mouth region of the liquid conveying path, one of which is directed against the side wall of the boundary of the mixing chamber and the other against the central core is.
  • the radius of the mixing plate can be between 30% and 70% of the radius of the spreading plate. Again, this is a favorable for a particularly uniform spreading pattern design. This is true in any case when the mixing tray and the spreading plate rotate in the same direction and at the same rotational speed, in particular by being coupled together. The latter is certainly not mandatory. Rather, it is also within the scope of the present invention that the mixed bottom and the spreading plate rotate at different speeds. It is even conceivable an opposite turning of mixed soil and spreading plate.
  • mixing chamber by no means implies that two different substances (eg a solid and a liquid or two solids such as a salt / grit mixture) are mixed there.
  • mixing instead of mixing
  • a substance eg salt
  • central mixing chamber clearly indicates that it extends around the axis of rotation of the mixing tray.
  • the mixing chamber 4 comprises a slightly profiled mixing bottom 5 which rotates together with the spreading plate 3 and a non-rotating boundary 6.
  • the latter consists essentially of a side wall extending around the common axis of rotation 1 of spreading plate 3 and mixing bottom 5 along a circular cylindrical surface 7 and an upper end part 8, which is connected to the side wall 7 along the upper edge thereof.
  • a window-like outlet opening 9 is provided through which scattering material passes from the mixing chamber 4 to the surrounding spreading plate 3.
  • the boundary 6 of the mixing chamber 4 is rotatably mounted within predetermined limits about the axis 1 in order to adjust the angular position of the outlet opening 9 and thus the Abschgeometrie.

  • the boundary 6 of the mixing chamber 4 is to be rotated counter to the direction of rotation A of the spreading disc 3.
  • the annular gap between the lower edge of the side wall 7 of the (non-rotating) boundary 6 of the mixing chamber 4 and the (rotating) spreading plate 3 is dimensioned so that leakage of scattering particles through the annular gap is avoided to a significant extent as well as jamming of scattering particles in the annular gap.
  • the peripheral edge of the mixing bottom 5 ends at a small distance above the spreading plate 3, which extends radially inwardly below the mixing bottom 5.
  • the spreading plate 4 has below the mixing bottom 5 drainage holes for liquid, which passes through the existing between the mixing tray and the spreading plate annular gap under the mixing tray.
  • the side wall 7 of the mixing chamber 4 changes its height in the circumferential direction above the mixing bottom 5. And accordingly also changes the upper end part 8 - in the circumferential direction of the mixing chamber 4 - adjacent to the side wall 7 its height above the mixing bottom 5.
  • the side wall approximately opposite to Scblin 11 and in an in the direction of rotation A of the spreading plate 3 and mixing tray 5 adjoining thereto angular range of about 120 ° to a maximum height, so that the upper end part 8 there also has a maximum height above the mixing tray 5.
  • the height of the side wall 7 of the mixing chamber 4 then gradually gradually reduced to only about 50% of its maximum height; and accordingly, the height of the upper end part 8 relative to the mixed bottom 5, which due to the opening 10 there is limited to a strip 13 extending along the upper edge 12 of the side wall 7, whose radial extent is about 15%, also decreases over the said second angular range.
  • the radius of the Sidewall 7 is, also steadily.
  • the upper end part 8 accordingly only about 50% of its maximum height above the mixing bottom fifth
  • the outlet opening 9 extends over an angular range of about 45 °, i. over about one third of the angular range within which the height of side wall 7 and upper end portion 8 is reduced in the manner described above.
  • the edge 15 which delimits the outlet opening does not abruptly rise at the beginning 14 of the outlet opening, but rather gradually, so that the height of the outlet opening 9 above the mixing floor 5 increases over an angular range in the direction of rotation A of the mixing floor 5.
  • the maximum height of the outlet opening 9 and the lowest height of the upper end part 8 above the mixing bottom 5 essentially correspond to each other.
