Definitions

  • the invention relates to a winter service spreader, in the spreading material from an endless conveyor from a storage container into a downpipe lying in the same vertical plane and over an oblique, substantially U-shaped slide at a certain point on a spreading plate, which is essentially a vertical axis rotates with adjustable speeds and which is arranged eccentrically to the downpipe and for transverse displacement of the spreading pattern with respect to the longitudinal central axis of the spreading device together with the slide pivotally mounted about the vertical axis of the downpipe lying in the plane of this longitudinal central axis and adjustable in different angular positions to the longitudinal central axis and by means of which the spreading material is spread centrifugally to different degrees depending on the speed.
  • Winter service spreading devices of the generic type are known (DE-A-17 59 898, DE-A-19 36 568), in which the spreader plate shaft is mounted outside the downpipe on a support which can be pivoted about the axis of the downpipe and in different angular positions the downpipe is noticeable.
  • a transmission gear can be provided, which can be adjusted via a flexible shaft by a rotatable adjusting element arranged in the driver's cab of the spreading vehicle, a mechanically driven scatter image indicator being provided on the adjusting element and indicating the respective angular position of the spreading disc.
  • the spread pattern is adapted to different spread widths by changing the speed of the spreading disc, with a larger throwing distance being achieved at higher speeds. Since the throwing distance increases towards the rear as well as towards both sides, a large area of the roadside would be sprinkled with spreading material without a corresponding change in the spread pattern.
  • two guide devices are arranged above the spreader plate, each of which receives incoming spreader material through a vertical downpipe arranged symmetrically to the longitudinal center plane of the spreader Direct part of the spreading material to separate locations on the spreading disc. With its vertical axis of rotation, the spreading disc is pivotally mounted on a support around the lower end of the downpipe.
  • the two guide devices which are each designed in the form of a slide, are also fixedly arranged with this support. Above these guide devices, an adjustable material switch is arranged in the downpipe, which makes it possible to divide the flow of grit coming from the downpipe between the two guide devices.
  • the spreading plate leads through the two guide devices at different locations in different or equal proportions onto the spreading plate, whereby a larger spreading width is achieved, since the spreading material is spread in two different directions predetermined by the point of impact from the spreading plate .
  • the direction of spreading is changed on the one hand by changing the spreading disc speed, although the spreading range is changed at the same time, and on the other hand by pivoting the spreading disc directly around the lower end of the vertical downpipe.
  • the change in the spreading pattern with respect to the longitudinal central axis of the spreading vehicle takes place through the Swiveling of the spreading disc around the vertical axis of the downpipe, so that there is a change in the scattering direction.
  • the total pivoting angle with respect to the downpipe axis greater than 60 °.
  • this change in direction of the spreading pattern is not sufficient to keep the adjacent right side of the road free of spreading material.
  • a transverse displacement of the spreading plate with respect to the longitudinal central axis of the spreading vehicle or of the spreading device during pivoting is too small due to the very small pivoting radius of the spreading plate axis with respect to the downpipe axis.
  • a larger pivoting of the spreading disc would be necessary in order to achieve a sufficient transverse displacement of the spreading disc in the direction of the left-hand lane edge, so that the right-hand lane edge can be kept free of spreading material.
  • this is not possible or sensible due to the geometrical mounting conditions specified by the spreading device or the spreading vehicle, since with larger swiveling angles the spreading disc on the one hand is swung under the spreading vehicle and on the other hand the spreading material would be partially spread in the direction of travel.
  • the invention is therefore based on the object of creating a winter service spreading device with an adjustment device for the spreading plate, which allows a sufficient transverse displacement of the spreading pattern or minimum and maximum throwing range within a limited total pivoting angle of the spreading plate with respect to the longitudinal center axis of the spreading device. to achieve the spreading carpet with the most uniform possible distribution of spreading material within a specified spreading width.
  • Another important advantage is that the inclined position of the guide tube makes it considerably better Bundling of the spreading material flow and thus a more precise adherence to the point of impact of the spreading material on the spreading plate is achieved. As a result, considerably more uniform scatter patterns are achieved across the entire speed range.
  • Claims 2 to 5 relate to advantageous structural configurations of the invention, which contribute to a high level of functional reliability and compact construction.
  • Fig. 1 shows the basic structure of a spreading device 1 of a generic winter service spreading device.
  • a short vertical downpipe 3 is attached to an essentially horizontally extending conveyor pipe 2, in which a screw conveyor is mounted as an endless conveyor.
  • This downpipe 3 is provided with a tapered coaxial downpipe socket 4.
  • the downpipe socket 4 is provided in the upper third with a circumferential flange ring 5, on which the inner ring 5 'serves to receive a pivot bearing 6.
  • the pivot bearing 6 is designed as a radial ball bearing and is attached with its outer bearing ring 7 'to a circumferential bearing flange 7.
  • the bearing flange 7 is welded to the upper end of a short bearing socket 8, which forms the short vertical upper end section of a guide tube 9, which runs coaxially to the downpipe socket 4.
  • the guide tube 9 runs obliquely from above at an angle of inclination ⁇ of at least 20 ° to the vertical 10 down below.
  • the sloping guide tube 9 has at its lower end 11 a cut surface 13 lying in a vertical plane 12, to which a mounting plate 14 is welded.
  • a support frame 34 is screwed to the mounting plate 14 and, together with a slide 15, carries the actual spreading unit 16.
  • This consists of a spreading plate 17 with a drive shaft 19 which can be driven rotating about a substantially vertical axis of rotation 18 at different speeds, and a hood-like spreading plate cover 20 which has a recess 21 into which the slide 15 dips, and also from a hydraulic drive motor 22.
  • the chute 15 which is inclined with its lower apex line 24 to the central axis 25 of the guide tube 9 by approximately 5 ° to 10 °, the spreading disc 17 is supplied approximately centrally.
  • the granulated grit coming from the conveying tube 2 is compressed into a largely homogeneous concentrated stream, so that it strikes the scatter plate 17 at approximately the same point.
  • This point lies in a vertical plane which is at the same time the radial plane to the axis of rotation 18 of the spreading plate 17 and also to the pivot axis 10 'of the pivot bearing 6.
  • the linear drive 27 is fastened with its push cylinder 29 in the console holder 28, the console holder 28 having a tab 31 provided with a bore 30 for the articulated connection to the bearing arm 26.
  • Attached to the bearing housing 7 of the bearing socket 8 is a swivel arm 32 which runs radially to the swivel and downpipe axis 10 'and is approximately twice as long as the bearing arm 26 and with the end of which the linear drive 27 is mounted connected to its push rod 33.
  • the swivel arm 32 extends horizontally above the guide tube 9.
  • the bearing arm 26 and the swivel arm 32 In the central position shown in solid lines in FIG. 3, the bearing arm 26 and the swivel arm 32 have an angle ⁇ of approximately 45 ° to one another.
  • the length ratios of the bearing arm 26 and the swivel arm 32 are matched to the maximum stroke of the linear drive 27 such that a from this central position Swiveling the guide tube 9 together with the support frame 34 and the parts 15, 16, 17, 19, 20, 22 attached to both sides to the same extent is possible by a pivot angle ⁇ of approximately 30 ° to 35 °.
  • the vertical distance a between the spreading plate 17 and the pivot bearing 6 is optimally large, so that there is also a pivoting radius due to the inclined position of the guide tube 9 by the angle ⁇ to the vertical 10 r of at least 70 cm. This ensures that when pivoting the spreading unit 16 from one extreme position to the other by the entire pivot angle 2 ⁇ there is a maximum transverse displacement of over 70 cm.
  • a spreading vehicle 36 which can be achieved with a spreading device 1 when the spreading vehicle 36 is stationary.
  • the spreading device 1 is arranged on the rear of the spreading vehicle 36 provided with a transverse baffle 37 that its pivot axis 10 'lies in the vertical longitudinal center plane 39 of the spreading vehicle 36.
  • the spreading width is 6 m in each case.
  • the spreading device 1 is shifted to the right by the pivoting angle ⁇ of approximately 30 °.
  • the impact apron prevents the roadway from being sprinkled in front of and below the spreading vehicle 36. This is shown schematically by the boundary lines 40 and 41, which run from the axis of rotation 42 of the spreading plate 17 through the respective outer edge of the impact apron 37.
  • the spreading disc 17 rotates in the direction of arrow 43, that is to say in the clockwise direction. It can be seen that the largest throw range results approximately in the direction of the symmetry line 44/1 of the scatter pattern 35/1. From this line of symmetry 44/1 the scattering width along the dash-dotted line 45 decreases continuously in both directions.
  • the right outer edge of the scatter pattern 46 is at a distance of approximately 3.45 m from the longitudinal center plane 39 of the spreading vehicle 36, while the distance of the left outer edge of the scatter pattern 47 from the longitudinal center plane 39 of the spreading vehicle 36 is 2.55 m. These two distances together make up the total spread of 6 m.
  • the spreading plate is pivoted to the right by a pivot angle ⁇ 1 of 30 ° with respect to the longitudinal center axis 39 of the vehicle 36.
  • the scatter pattern symmetry line 44/1 forms an angle ⁇ with the longitudinal center axis 39 of the vehicle which is smaller by the angle ⁇ than the swivel angle ⁇ 1 of 30 °.
  • ⁇ is the angular distance that the scatter pattern symmetry line 44/1 forms with the center line 48 of the scatter plate 17 that runs through the axis of rotation 10 ′.
  • the spreading plate 17 is pivoted by the pivot angle ⁇ 2 of 30 ° to the left, so that the line of symmetry 44/1 of the stationary scatter pattern 35/3 with the
  • the scatter pattern 35/3 extends 2.25 m to the right and 3.75 m to the left with respect to the longitudinal central axis 39.
