Definitions

  • the present invention relates to a spreading plate for a winter spreader for spreading grit such as salt, brine, split or the like, as well as a spreading plate assembly.
  • spreading plates for the spreading of grit known.
  • Such spreading plates have, for example, a horizontally oriented rotatable spreading plate on which spreading material is applied from above. Due to the spreading plate rotation, the spreading material is conveyed to the outside and thus conveyed to a surface to be spread, such as a road.
  • EP 0 490 208 B1 shows a scattering plate, which supports with different shaped throwing blades, the promotion of the grit.
  • DE 1 015 3982 C1 the ejection angle of the spreading plate is variable.
  • DE 8 709 321 U1 individual strips screwed onto a flat spreading plate ensure spreading of the spreading material.
  • the object of the invention is to provide a spreading plate and a spreading plate assembly with which the spreading material can be applied particularly effectively and uniformly.
  • the scattering plate should also be simple to build and finished and have a particularly good stability.
  • the scattering plate according to the invention has a disc-shaped lower part rotatable about a rotation axis and a plurality of throwing blades arranged on the spreading plate lower part.
  • the throwing blades are at least partially, preferably predominantly, particularly preferably completely covered by an annular spreading plate upper part, which is connected via the throwing blades with the spreading plate lower part. Between the spreading plate upper part and the scattering plate lower part, a radially outwardly open gap for the spreading material is provided.
  • the inventively provided spreading plate upper part thus forms an upper cover, which prevents the spreading material is unceremoniously thrown upwards during rapid rotation of the spreading plate.
  • This guide is advantageously provided on the radially outer region of the scattering plate and extends in particular over at least a quarter, preferably over at least one third of the radial extent of the spreading plate. It is readily possible that this guide extends over half of the radial extent of the spreading plate.
  • the scattering plate top prevents swirling of the grit in the area of the throwing blades and also causes a suction effect on the supplied grit, which is usually fed centrally by means of a chute the spreading plate.
  • the scraper supply and -ausbringung thus takes place in a particularly effective and uniform manner.
  • the scattering plate base has an upwardly facing concavity. It is thus ensured that the grit when leaving the spreading plate undergoes an upward movement component, which supports the width of the spreading of the grit even at low rotational speeds of the spreading plate rotation.
  • the spreading plate upper part can preferably be designed as a flat disc. This is a cost-producible form.
  • the height of the gap for the spreading of the grit may decrease at least in regions with increasing distance from the axis of rotation.
  • the height of the gap decreases successively and continuously over the entire area in which the throwing blades are located.
  • the spreading plate lower part and the spreading plate upper part and preferably also the throwing blades are preferably made of a material of constant thickness, in particular a sheet metal, made.
  • the thicknesses of the spreading plate top and bottom and the throwing blades can each be different.
  • the throwing blades consist of flat profile elements, whereby they can be produced in a simple and cost-effective manner.
  • Other shapes, for example domed throwing blades, are readily possible.
  • the spreading plate lower part can in particular be inseparably connected to the spreading plate upper part via the throwing blades, in particular welded. This results in a high rigidity and life of the spreading plate.
  • the throwing blades can be made of a thinner or thicker material than the scattering plate lower and upper part.
  • the spreading plate base has the same outer diameter as the spreading plate upper part and the throwing blades extend up to this outer diameter.
  • a Venturi nozzle effect is effected, which improves the suction effect of the grit from the channels.
  • the splitter assembly comprises an at least partially frusto-conical shaped impact body to which the scattering plate base is attached and which has a frusto-conical portion which is arranged between the scattering plate base and a plane in which the spreading plate upper part is located.
  • this frusto-conical section for example, via a chute fed Scattering be introduced in a particularly effective manner in the gap between the spreading plate bottom and the spreading plate top.
  • the in the FIGS. 1 to 4 Spit cell assembly shown comprises a drive motor 2, with a scattering plate 6 can be rotated about a rotation axis 1 via a drive shaft 7 in rotation.
  • the drive shaft 7 is within a tubular bearing housing 3 by means of a Storage, in particular by means of ball bearings 8, 9, rotatably mounted.
  • FIG. 3 is a possible direction of rotation R drawn.
  • the bearing housing 3 can be attached to a holder, not shown, of an associated spreader.
  • a bolt connection 4.1 lying in the axis of rotation 1 baffle body 4.
  • a spreading plate bottom 6.1 is attached, which in turn is connected via a plurality of throwing blades 6.2 with a spreading plate upper part 6.3.
  • the spreading plate parts 6.1 and 6.3 form with the throwing blades 6.2 the spreading plate 6, which is releasably secured to the impact body 4.
  • the bolt connection 4.1. can be designed as a secured with a nut screw connection. Any other positive and / or non-positive connections are also possible.
  • the baffle preferably has two areas, namely, on the one hand, an upper holding area, which serves with the bolt connection 4.1 for the rotationally fixed connection to the drive shaft 7, and, on the other hand, a lower frustoconical area.
  • a spreader litter of the spreader which consists of an upper spreader slide 14 and a lower spreader slide 17 (see Fig. 6 ), ensures that the grit in an in FIG. 2 shown Streugutzu Glasstechnisch 5 hits the baffle 4.
  • the grit feed direction may be vertical or oblique.
  • the truncated cone region of the impact body 4 which widens downwards, ensures that the scattering material already has something relative to the axis of rotation 1 is transported radially outward and subsequently lands on the spreading plate bottom 6.1.
  • the contact of the grit with the baffle body 4, the spreading plate bottom 6.1, the throwing blades 6.2 and the spreading plate top 6.3 ensures that the rotational movement of the rotating driven spreading plate 6 is transmitted to the spreading material and a centrifugal force is generated, which flings the spreading material radially outward.
  • the throwing blades 6.2 are preferably designed as flat sheet-metal parts which extend radially and whose alignment planes are each coplanar with the axis of rotation 1.
  • the spreading plate lower part 6.1 may be a flat plate, but it is preferably formed rising to the edges, so that a plate-shaped region is formed, which also causes the ejected from the spreading plate 6 spreading material receives an upward directional component.
  • the spreading plate upper part 6.3 which represents a cover plate and can be formed in particular by an annular plate.
  • the plate is flat in the embodiment shown, but may also, for example, similar to the spreading plate bottom 6.1, have an upward slope or be curved differently.
  • the spreading plate upper part 6.3 has a central recess 10.
  • the concentric inner diameter of the spreading plate upper part 6.3 is dimensioned such that an inner region is free, through which the spreading material can reach the baffle body 4 and the spreading plate lower part 6.1.
  • the spreading plate top 6.3 is in particular above the lower frusto-conical portion of the impact body 4.
  • the outer diameter of the spreading plate upper part 6.3 preferably corresponds to the diameter of the spreading plate bottom part 6.1.
  • the production is inexpensive. Slit-like regions which are adjacent to the throwing vanes 6.2 and whose width corresponds to the thickness of the throwing vanes 6.2 can be cut out in the spreading plate lower part 6.1 and spreading plate upper part 6.3.
  • the throwing blades 6.2 then have corresponding web-like projections which engage in the slot-like regions according to the tongue and groove principle.
  • the spreading plate can be easily assembled with an exact positioning of the throwing blades 6.2.
  • a weld may be provided to connect these parts easily, inexpensively and permanently.
  • the structure described above is also the FIGS.
  • throwing blades 6.2 extend radially inwardly to the inner diameter of the ring of the spreading plate upper part 6.3.
  • six throwing blades 6.2 are shown, however, a different number of throwing blades 6.2 is readily possible.
  • Fig. 5 shows the installation of the spreading plate 6 in a spreader.
  • the spreader may be an integral part of a scattering vehicle or be releasably connectable with it.
  • the scatter vehicle has a grit container 11 (see Fig. 6 ), which contains in its lower region a screw conveyor 12 which is connected to a drive motor 13 to direct the grit from the grit container 11 to the spreading chute 14 and 17. From the spreading chute 14, 17, the grit falls against the baffle 4, from which it, as already described, through the gap h is issued. As already described, the gap height decreases with increasing radial extent.
  • the spreading plate assembly is pivotable about a plurality of axes relative to the spreading vehicle. First, it can be folded up completely manually. For this purpose, a horizontal pivot axis 30 is provided. In addition, the spreader assembly can be automatically swivel left or right from the point of view of the spreader vehicle. For this purpose, a vertical pivot axis 21 is provided with a corresponding drive motor 22. In addition, the upper part of the spreading turkey 14 against the lower part 17 is pivotable. These swivel types can be used to set a large number of different grit ejection directions.
  • the drive motor 13 via the rotation of the screw conveyor 13, the amount of grit to be issued before. Furthermore, can be determined by the speed of the drive motor 2 of the spreading plate 6, the amount and throw of the grit and thus the size of the covered area.
  • the material for the spreading plate base 2.1, the throwing blades 2.2 and the spreading plate top 2.3 is preferably metallic, such as e.g. made of a stainless steel with a high abrasion resistance.
  • the thickness of the corresponding sheet is at least 1.5 mm and in other embodiments at least 2.5 mm.
  • the outer diameter of the spreading plate is at least 15 cm and in preferred embodiments at least 25 cm.
  • the baffle 4 is made of a solid metal material and comprises a central axial bore, which serves to receive the drive shaft 7, and the already described outer frusto-conical contour, which serves as a baffle surface for the grit.
