Definitions

  • the invention relates to a spreading plate for a winter service spreader, which is driven in rotation about a rotation axis and on its upper side has radially extending throwing blades which divide the spreading plate between them into segments.
  • the spreading plate should distribute the spreading material as evenly as possible across the width of the roadway. To achieve this goal is out of the DE 40 30 795 C1 known to arrange the radially inner ends of all throwing blades on the same radius and the radially outer ends of the throwing blades at different radii, the outer edge of the spreading plate in the radial direction to the rotation axis flush with the outer ends of the individual throwing blades. By aligning the contour of the spreading plate to the different ends of the individual throwing blades arise different grit compartments with different throw sizes and different widths, so that the non-uniform spreading material distributions can be compensated within the grit compartments of the longer throwing blades through the smaller grit compartments of the smaller throwing blades.
  • a spreading plate is known, on the surface of which a concave or convex shape can be adjusted to adapt to a desired spreading tendency.
  • the invention is based on the object to find another approach to achieve a uniform spreading material distribution over the desired spread.
  • the spreading plate according to the invention for a winter service spreader has a spreading plate surface which is driven to rotate about a rotation axis and provides on the scattering plate surface radially extending throwing blades, which divide the spreading plate between them into segments, wherein at least some, preferably all the adjacent segments at least part of the spreading plate surface is formed with different inclinations relative to the axis of rotation.
  • the differently inclined segments cause correspondingly different casting distances, which complement each other to a very uniform scattering pattern.
  • some, preferably all adjacent segments have different sizes.
  • angles of inclination of the segments are in the range of 0 ° ⁇ ⁇ 30 °, preferably 0 ° ⁇ ⁇ 20 °.
  • At least 50%, preferably 80 to 100%, of the radial extent of the spreading plate surface of the segments is inclined relative to an inner region of the spreading plate.
  • the inclination is achieved for example by Aufkantung the scattering plate surface relative to an inner region of the spreading plate.
  • the throwing blades are arc-shaped or rectilinear.
  • the scattering plate is circular in plan view and the radially inner ends of the throwing blades are arranged at the same radial distance from the axis of rotation.
  • the radially outer ends of the throwing vanes preferably have the same radial distance from the axis of rotation.
  • the scattering plate may be subdivided into a plurality of groups, each having at least two, preferably three to five, throwing blades which are each constructed the same, wherein within a group the inclination of the spreading plate surface of adjacent segments increases or decreases continuously.
  • - seen in the circumferential direction of the spreading plate - the inclination of the spreading plate surface of adjacent segments is alternately larger and smaller than the previous inclination is formed.
  • the invention relates to a spreader with a spreading plate according to the type described above, at least one storage container for grit and a feeder to supply the grit from the reservoir to the spreading plate.
  • the invention comprises a winter service spreader with such a spreader.
  • This in Fig. 1 illustrated winter service spreader 1 has a spreader 2, which essentially comprises the following components: a first reservoir 3 for a first spreading material (for example, salt), a second reservoir 4 for a second spreading material (for example brine), a spreading plate 5 and a feeder 6, to supply the spreading material from the storage containers to the spreading plate 5.
  • a first spreading material for example, salt
  • a second reservoir 4 for a second spreading material for example brine
  • a spreading plate 5 for example brine
  • a feeder 6 to supply the spreading material from the storage containers to the spreading plate 5.
  • the scattering plate is rotatably drivable about a rotation axis 7 and has on its spreading plate surface radially extending throwing blades 8, which divide the spreading plate between them into segments 9.
  • At least the radially outer regions 5a of the spreading plate surface of adjacent segments have different inclinations.
  • the inclination angles of the scattering plate surfaces with respect to a perpendicular to the axis of rotation are in the range of 0 ° ⁇ ⁇ 30 °, preferably 0 ° ⁇ ⁇ 20 °.
  • the radially outer portions 5a of the spreading plate surfaces against an inner portion 10 of the spreading disc are the angles ⁇ 1, ⁇ 2, ⁇ 3 or ⁇ upstands 4, wherein ⁇ 1 ⁇ 2 ⁇ 3 ⁇ . 4
  • the throwing blades 8 are formed here in a straight line and arranged with the radially inner ends with the same radial distance from the axis of rotation 7.
  • the radially outer ends of the throwing blades 8 are arranged at the same radial distance from the axis of rotation, so that the scattering plate is circular in plan view.
  • the scattering plate can be divided into several groups of at least 2, preferably 3 to 5 throwing blades with associated segments.
  • Fig. 2 For example, three groups each with four segments 9 are provided, wherein the successive segments of a group - seen in the circumferential direction, with an ever-increasing angle ( ⁇ 1 , ⁇ 2 , ⁇ 3 , ⁇ 4 ) are folded up. After the segment with the Aufkantungswinkel ⁇ 4 then again follows a segment with the Aufkantungswinkel ⁇ 1 and so on.
  • Fig. 4 is a second embodiment of a spreading plate 5 'is shown, which in turn on its spreading disc surface radially extending throwing blades 8' provides that the scattering plate between them in segments 9'a, 9'b, 9'c, 9 "a, 9" b and 9 "c subdivide.
  • a part of the spreading plate surface with different inclinations with respect to the axis of rotation are also formed here at least in some, preferably in all adjacent segments.
  • the size of the segment corresponds to the magnitude of the inclination such that the smallest segment 9'a has the smallest inclination (for example in accordance with FIG Fig. 3a ), the middle-sized segment 9'b has an average inclination (for example according to FIG Fig. 3b ) and the large segment 9'c has a large inclination (for example according to FIG Fig. 3c ) having.
  • Fig. 4 shown spreading pattern, which of course in each segment the same grit is included. Only To represent the scattering pattern, different symbols (square, triangle, circle) were used for the spreading material in the individual segments of a group.
