  • the solution according to the invention has the additional advantage that the pivotable mounting and thus the entire weight holder is arranged on the top of the discharge head, so that the The bottom of the discharge head can be made much simpler and the installation of the downpipe on the discharge head can also be carried out much easier, since there is the possibility of increasing the bearing yoke without the support bracket with the downpipe and the spreading plate to assemble and then connect the support bracket to the support brackets of the bearing yoke using the tilting bearings.
  • the configuration according to claim 2 results in a very simple and inexpensive embodiment of the pivot bearing, the axial bearing also absorbing the vertical forces, even if this is designed as a ball or roller bearing, much cheaper because it only requires a relatively small diameter and as a commercially available one , standardized component is available inexpensively.
  • the yoke beam and with it the downpipe can be fixed with the spreading plate in a very simple manner in the desired pivoting position, but there is also the possibility of a remote-controlled adjusting device without the locking screw or when the locking screw is not tightened use, through which different pivot positions of the spreading plate with respect to the Have the vertical swivel bearing axis and thus infinitely adjustable with respect to the longitudinal center plane of the entire spreader in the direction of travel.
  • the spreading device 1 shown in the drawing is part of a winter service spreading device which can be placed or placed on the loading platform of a spreading vehicle, not shown in the drawing.
  • the winter service spreader has an outlet head 3 flanged to a conveyor tube 2 projecting rearward of the loading platform of the motor vehicle.
  • This outlet head 3 has the shape of a substantially rectangular housing with an upper, horizontal cover 4, two parallel, vertical side walls 5 and 6, a rear end wall 7 and a flange ring 8, through which it is connected to a flange ring 9 of the delivery pipe 2 with screws is attached.
  • the rear end wall 7 is provided with a central bearing 10, in which the screw conveyor, which is not shown in the drawing and extends through the conveyor tube 2, is rotatably mounted with its shaft end.
  • the discharge head 3 is provided with a vertical discharge pipe socket 11, which in turn has a funnel-like conical, flexible, preferably made of rubber funnel sleeve 12 through which the grit, for example sand, split or de-icing salt, which is conveyed into the discharge head 3 by the screw conveyor, not shown, is directed into a downpipe 13, at the lower end of which there is a scattering unit 14 with a rotating spreading disc 15.
  • grit for example sand, split or de-icing salt
  • the downpipe 13 is formed in two parts. It consists of an upper tube part 16 and a lower tube part 17, the upper tube part 16 projecting telescopically into the lower tube part 17. These two pipe parts 16 and 17 can be non-rotatably connected to one another by a clamping ring 18.
  • Link chains 20 are provided on both sides to absorb the forces exerted by the weight of the scattering unit 14 on the lower tube part 17, which furthermore make it possible for the lower tube part 17 with the scattering unit 14 to be hooked on and fastened to the upper tube part 16 in different height positions.
  • the downpipe 13 is inclined obliquely to the vertical 19 by an angle of inclination ⁇ of approximately 10 to 15 ° to the rear.
  • ⁇ an angle of inclination
  • the spreading plate 15 is covered by an annular cover 23 upwards. It can be rotated about a vertical axis of rotation 23 and is controlled by a hydraulic motor 24.
  • a mounting bracket 25 and a support plate 26 the entire spreading unit 14 rigidly connected to the lower pipe part 17 of the down pipe 13.
  • the upper open end of the downpipe 13 or of the upper tube part 16 is fastened, in particular welded, to the horizontal, plate-like web part 30 of a support bracket 34 provided with two lateral, upwardly directed vertical walls 31 and 32, the web part 30 having an inner diameter of the tube part 16 corresponding passage opening 35 is provided.
  • These vertical walls 31 and 32 are each connected by mutually coaxial, horizontal tilting bearings 36 and 37 to both sides of the discharge head symmetrically and at a lateral distance from each other, vertical support straps 38 and 39 of a bearing yoke 40.
  • the two pivot bearings 36 and 37 are formed by journals 41 and 42, which are mounted in mutually coaxial bearing bushes 43 and 44 of the side walls 31 and 32 and bearing bushes 45 and 46 of the brackets 38 and 39.
  • the bearing journals 41 and 42 each have threaded projections 47 and 48, onto which threaded nuts 49, 50 are screwed for the axial position fixing.
  • the spreading device 1 consisting of the downpipe 13 and the spreading unit 14, can be used together with it load the supporting bracket 34 about the common tilt bearing axis 51 (FIG. 3) from the working position shown in FIG. 1 into the rest position shown in FIG. 2.
  • the rest position is always used when the spreader vehicle has to cover longer distances without spreading.
  • both the two vertical walls 31 and 32 of the mounting bracket 34 and the mounting brackets 38 and 39 of the bearing yoke are in each case with plug holes 52, 53 which are spaced from the tilting bearing axis 51 at corresponding intervals , 54, 55, 56, 57 and 58, 59 provided for receiving locking bolts 60 and 61, respectively.
  • the locking pins 60 and 61 are located in the bores 52 and 54 or 53 and 55, which in this position each take pairs of coaxial or mutually aligned positions.
  • the locking bolts 60 and 61 In the upward tilted rest position of the spreading device 1, which is shown in FIG. 2, the locking bolts 60 and 61, on the other hand, are in the plug bores 56 and 58 and 57 and 59.
  • the bearing yoke 40 has a horizontal, preferably made of a metal tube with a square cross section Yoke beam 62 on which the two support brackets 38 and 39 are welded downwards in a parallel position to each other.
  • the yoke beam 62 is provided with a vertically penetrating bearing bush 63, which is provided for receiving a cylindrical, vertical bearing journal 64 arranged centrally on the top of the cover 4 of the outlet head 3.
  • the bearing pin 64 is provided with an axial bearing 65, which is preferably designed as a ball or needle bearing and on which the bearing bush 63 rests with its lower end face. (See Fig.
  • the bearing bush 63 thus transmits the entire weight of the spreading device 1 to the thrust bearing 65 of the journal 64 or via this thrust bearing 65 to the cover 4 of the discharge head 3.
  • the bearing bush 63 welded to the yoke beam 62 and thus rigidly connected to it forms, together with the bearing journal 64 and its axial bearing 65, a pivot bearing 66 with a vertical pivot axis 67, about which the entire spreading device 1 can be pivoted relative to the outlet head 3 or delivery pipe 2, so that the spreading unit 14 with the axis of rotation 23 of the spreading plate 15 can assume two different positions in the transverse direction to the longitudinal axis of the vehicle or in the transverse direction to the delivery pipe.
  • a cover disk 68 with one in a front threaded bore 69 of the journal 64 screw-in locking screw 70 is provided.
  • the yoke beam 62 is provided on the back with a clamping plate 71 which has a slot 72 concentric with the vertical pivot axis 67 of the pivot bearing 66. Below this clamping plate 71 there is a threaded bushing 73 on the cover 4 of the discharge head 3 in the pivoting range of the slot 72, into which the threaded pin 74 of a toggle screw 75 can be screwed through the slot 72.
  • This toggle screw 75 is provided at the upper end of the threaded pin 74 with a clamping flange 76, which is seated on the upper side on the edge of the slot 72 of the clamping plate 71 and, when tightened, presses the clamping plate against the end face of the threaded bushing 73 and thus fixes it.
  • yoke beam 62 On the top of the yoke beam 62 are arranged outside of the support brackets 38 and 39 at a distance which corresponds to the distance between the two vertical walls 31 and 32 of the support bracket 34, rearward-looking support fingers 77 and 78, with their upper ends made of gas springs Support existing spring elements 79 and 80 in an articulated manner (FIG. 4), the lower ends of which are each articulated are articulated with finger-like projections 81 and 82 eccentrically to the bearing bushes 43 and 44 of the two vertical walls 31 and 32 of the support bracket 34.
  • the arrangement is such that the spring elements 79 and 80 at least largely compensate for the torque resulting from the weight of the spreading device when the spreading device is tilted up and down, so that an individual is able to remove the spreading device from the working position shown in FIG to tilt the rest position shown in Fig. 2 and vice versa.
  • this type of mounting of the spreading device 1 on the discharge head 3 also enables the pivoting movements or the lateral adjustment of the spreading device to be carried out with the aid of a motorized adjusting device, as is the case, for example, with the known spreading device according to DE 4016369A . 4 and 5, which can be seen in particular from FIGS. 4 and 5, the support straps 38 and 39 of the bearing yoke 40 lying in the assembled state within the side walls 31 and 32 of the mounting bracket 34 from the side walls 5 and 6 of the outlet head 3 ensure that a sufficient large pivoting movement of the bearing yoke on the discharge head 3 is possible.
  • Stabilization of the pivot bearing 66 can be provided on the outlet head 3 additional directly acting on the support brackets 38 and 39 or on the yoke beam 62 support devices. So it is e.g. conceivable to provide the two side walls 5 and 6 of the outlet head 3 with circular segment-like support elements which are in contact with the inner sides of the support straps 38 and 39, but which do not impede the pivoting of these support straps 38 and 39 due to their outer circular contour.
