SPREADING VEHICLE WITH SLOPING SPREADING DISCS AND FILLER PIECE

Abstract

A spreading vehicle, e.g. universal spreader, comprises at least two spreading discs by which spreading material is thrown. The spreading discs are mounted at the rear end of the spreading vehicle and, on the top side, comprise drivers by which spreading material is captured. The spreading discs rotate with a predetermined rotational speed about their axis of rotation, and are inclined relative to the horizontal, transversely to the travelling direction of the spreading vehicle, by a predetermined non-zero angle. Between the spreading discs, at least partially, a filler piece is arranged to feed spreading material to the spreading discs. The filler piece has a center axis and extends in the direction of the centre axis along a portion having a portion length between the spreading discs. The portion length is greater than a radius of the spreading discs and in cases smaller than twice the radius of the spreading discs.

DETAILED DESCRIPTION

[0020] FIG. 1 shows a spreading vehicle 100, which is configured in particular as universal spreader. In FIG. 1, merely the rear of such a spreading vehicle 100 is shown. The spreading vehicle 100 comprises at least two spreading discs 2, 4, which are mounted at the rear end of the spreading vehicle 100. By means of the spreading discs 2, 4, spreading material is captured from a loading surface 6 (only indicated here) of the spreading vehicle 100 and thrown out by the spreading vehicle 100. For this purpose, the spreading discs 2, 4 comprise top-side drivers 8, by means of which the spreading material is captured, which material is continuously conducted or falls down onto the spreading discs 2, 4 from above. The spreading discs 2, 4 rotate with a predetermined rotational speed about their axis of rotation 10 (see FIG. 2), wherein the spreading discs 2, 4 are inclined relative to the horizontal transversely in the direction of a travelling direction 12 of the spreading vehicle 100, as is noticeable in particular in the FIGS. 3 to 5.

[0021] In particular, the first spreading disc 2 has an angle of inclination .sub.1 relative to the horizontal. The second spreading disc 4 has an angle of inclination .sub.2 relative to the horizontal. Between the spreading discs 2, 4 a filler piece 14 is arranged. The spreading discs 2, 4 are arranged in a spreading chamber 28.

[0022] The filler piece 14 is equipped in order to avoid that spreading material, which enters the spreading chamber 28, can unaccelerated slip through between the spreading discs 2, 4. The filler piece 14 extends as far as to an outlet side 38 of the spreading chamber 28. The spreading vehicle 100 additionally comprises at the rear end of the spreading vehicle 100 a rear-end flap 40. Further details of the spreading vehicle 100 are shown in the FIGS. 2 to 5 in different views. The filler piece 14 has a center axis 16. Originating from the center axis 16, a first surface 18 and a second surface 20 extend. The first surface 18 extends, originating from the center axis 16, in the direction of the first spreading disc 2. The second surface 20 extends, originating from the center axis 16, in the direction of the second spreading disc 4. The first surface 18 has an angle of inclination .sub.1 relative to the horizontal. The second surface 20 has an angle of inclination .sub.2 relative to the horizontal. The angle of inclination .sub.1 of the first surface 18 substantially corresponds to the angle of inclination .sub.1 of the first spreading disc 2. The angle of inclination .sub.2 of the second surface 20 substantially corresponds to the angle of inclination .sub.2 of the second spreading disc 4. The center axis 16 extends in the travelling direction 12 of the spreading vehicle 100. The filler piece 14 extends in the direction of the center axis 16 along a portion A with a portion length A.sub.1 between the spreading discs 2, 4, wherein the portion length A.sub.1 is greater than a radius r of the spreading discs 2, 4 and, in particular, smaller than twice the radius r of the spreading discs 2, 4.

[0023] The first spreading disc 2 and the first surface 18 form a common first plane E.sub.1. The second spreading disc 4 and the second surface 20 form a common second plane E.sub.2. The first surface 18 on its side facing the spreading disc 2 has an inside radius 22. The inside radius 22 substantially corresponds to an outside radius of the spreading disc 2. The second surface 20 on its side facing the second spreading disc 4 has an inside radius 22. The inside radius 22 substantially corresponds to an outside radius 24 of the second spreading disc 4.

[0024] Adjoining the surfaces 18, 20 a wall portion 26 is formed. The wall portion 26 extends, originating from the inside radius 22, substantially parallel to the axis of rotation 10 of the respective spreading disc 2, 4 to below the respective spreading disc 2, 4. The inside radius 22 of the surface 18, 20 is spaced apart from the outside radius 24 of the spreading disc 2, 4. Between the inside radius 22 and the outside radius 24, the spreading discs 2, 4 are spaced apart by a distance d in a radial direction r based on an axis of rotation 10 of the spreading discs 2, 4. The filler piece 14 has a length L along the center axis 16, which is greater than a radius r of the spreading discs 2, 4.

[0025] The spreading discs 2, 4 are at least partially received in the spreading chamber 28. The filler piece 14 comprises a first attachment portion 30. By means of the first attachment portion 30, the filler piece 14 is attached to a, in travelling direction, front limit 32 of the spreading chamber 28. The first attachment portion 30 is configured as a flat component, in particular metal sheet, arranged substantially vertically and transversely to the travelling direction 12, originating from which the surfaces 18, 20 extend.

[0026] The filler piece 14 extends in the direction of the center axis 16, originating from the first attachment portion 30, at least as far as to a position 34, in which the spreading discs 2, 4 have the least distance to one another. In the shown exemplary embodiment, the filler piece 14, originating from this position 34, extends in the direction of the center axis 16 opposite to the travelling direction 12. Further, the filler piece 14 comprises a second attachment portion 38 arranged opposite the first attachment portion 30. By means of the second attachment portion 36, the filler piece 14 is attached to an outlet side 38 of the spreading chamber 28.
