Definitions
- the invention relates to a spreader, in particular for mounting on a Vehicle for the optional spreading of grit sand, salt or the like - on the one hand by means of an approximately horizontal axis rotatingly driven so-called spreading roller on a strip-shaped Area whose strip width corresponds approximately to the axial length of the spreader roller, and on the other hand by rotating about an approximately vertical axis driven spreading disc on a by the extensive spread of the rotating spreading disc defined area, the two types of spreading means a reversing device can be switched on separately.
- the invention is based, a convertible device in question standing type in robust manufacture easier to handle and above also adjustable with regard to the amount of spreading material in the spreading roller operation embody.
- This task is carried out in the form of a spreader of the type mentioned Art solved according to the invention in that the litter roll from a in Scattering area of a grit storage container trained over its length distributed scattering openings and a staggered Passage for the transfer of the spreading material to the distribution surface of the spreading disc having tub underneath and that a spool adjacent to the tub bottom wall is slidably arranged along this has at least one - preferably several - transfer openings, which in Depending on the shift positions of the control spool, the spreading openings more or less releases in the tub bottom wall or under Closing the spreading openings opens the passage to the spreading disc.
- the invention is characterized in that not only a switchover from Spreading roller operation on spreading disc operation easy to handle, even during operation without stopping the moving spreader, but that the amount of time and / or route-dependent operation can be adjusted.
- the latter is particularly the case with the width-limited stray spread with a spreader roller.
- the spool is in a preferred embodiment between the Trough bottom wall and the roller arranged and either around an pivot axis parallel to the roller axis rotatable or in Axial direction of the roller axis slidable, the trough preferably a trough-shaped shape with a circular cross-section in particular Has tub bottom wall.
- the spool can be used as Spreading container be formed more or less open tube that in his a transition opening between the tub and the roller area has, depending on the pivoting position of the tube above the scattering openings or lies above the passage to the spreading surface of the spreading disc.
- This tubular spool can execute the tub bottom wall be designed to be interlocking and in turn in this area of grip have at least one transition opening which is in line with the scattering openings or the passage to the spreading surface of the spreading plate is optionally aligned or this releases.
- the spreader roller is preferably concentric with that in its arranged axially end regions tubular control slide, wherein in particular the tub comprises the roller by more than 180 °, in particular such that the axis of rotation of the spreader roller, the longitudinal axis of the curvature the tub and the axis of rotation of the tubular control slide are congruently arranged.
- tub floor wall is approximately flat trained who is an adjacent, correspondingly trained Control spool is assigned across or below, which in the case of Overlapping arrangement preferably in the axial direction of the spreader roller and in the case the grip arrangement preferably perpendicular to the axial direction of the Spreading roller is slidably guided.
- At least one shift position of the Control spool provided in which both the spreader openings and the Passage of the tub floor are closed.
- the spreading rollers that are preferred here have not only the function of a loosening distribution of the spreading material over its axial width away - width-limited spreading roller operation - but also the collection of the Spreading material for transfer to the preferably around a vertical axis rotating spreading disc, whose application area regularly in the Width middle range of the device lies.
- Such a function fulfills one "Spreading roller” in the form of one over the spreading openings in the tub stroking snail, the helix of which from the two axial ends seen towards the center have an opposite direction of rotation, so that the On the one hand, the screw spreads the spreading material in the width-limited spreading roller operation by sweeping over the scattering openings, this feeds evenly and to the others to transport the spreading material when the spreading openings close Axial center of the worm-shaped spreader roller in the passage for the spreading material on the upward distribution surface of the spreading disc is provided.
- the device in question could basically be used as a self-propelled machine be formed, preferably from the point of view of multiple Use of a self-propelled work vehicle as a trailer (possibly uniaxial), but especially as a so-called attachment, trained, preferably to the rear of a carrier vehicle on all known ways is interchangeable, for example via a Three-point hitch.
- the drive of both the spreader roller and the spreader plate is the furthest Limits can be configured as required, especially when training trailers Attachment, especially via a cardan shaft connection, but above all also realized by hydraulic motors.
- Both of the exemplary embodiments show one designated 0 overall Storage container that is conical in the area transverse to the direction of travel narrowing to a lower tub area tapers to the side below the Container is in a manner not shown - for example by a hydromotor - drivable spreading disc 2, which when Spreading material on its upper, in particular radially ribbed, surface of the spreading material thrown in the radial direction, as shown by the two-dot chain lines
- the storage container 0 is indicated as a trailer or Piggyback to a towing vehicle, not shown, which is related of Figures 1 and 4 moved to the right in the image plane
- the lower wall area of the storage container is replaced by a transverse to the direction of movement upwardly open tubular trough 6 in the first embodiment Figures 1 to 3 or through a trapezoidal trough with approximately horizontal extending bottom 19 formed-embodiment according to Figures 4 to 6.
- a screw conveyor 3 or the like arranged according to Figures 2 and 5 due to a in the opposite direction, the spiral is formed in the storage container 0 filled grit transported to the center.
- a loosening shaft 4 is arranged in each case, which is not shown in detail Way by radial spike formation or the like the grit to one processed as finely flowing as possible.
- the Tub bottom wall 9 of the partially tubular tub 6 has - see in particular Figure 3 - a series of subdivided perpendicular to the direction of travel successive scattering openings 5, which in the present example of the vertical center of the tub bottom wall 9 as seen in the direction of travel is arranged offset, while one in the transverse central region of the tub arranged passage 7 seen from this vertical center in Direction of travel is arranged shifted to the rear, via a guide channel 15 when the spreading material is released, it supplies the surface of the spreading plate 2, as in the Figures 1 and 4 is indicated schematically.
- both alternatively types of spreading to be set namely via the spreading openings than over the Scattering carpet extending the width of the device as indicated at 8 or through radial centrifuging over the spreading plate 2 are shown in FIGS. 1, 2 and 4, 5 reproduced in parallel.
- this is Cross-section of tub 6 extending perpendicular to the direction of travel formed in an arc of a circle, except for the row of the scattering openings 5 and the passage 7 closed down and up to Opened inside the reservoir.
- Adjacent to the inside the tub bottom wall 9 is also perpendicular to the direction of travel extending spool 1 provided between the tubular axial end areas is open up to the interior of the reservoir, such as this can be seen in FIG. 3 in an enlarged cross section.
- the tubular spool 1 is already inserted into the adjacent position on the inner surface of the bottom wall 9 with respect its rotatability is guided coaxially, which means additional storage in the direction does not exclude this position.
- FIG. 3 shows the rotational position in which the tubular control slide 1 by means of its transition openings 11 through an approximately overlapping rotational position the scattering openings 5 releases the tubular control slide 1 in Clockwise, then a position is reached in which the Transfer openings 11 in a closed area of the Trough the bond wall 9 so that neither the scatter openings 5 nor the passage 7 to the spreader plate 2 for the supply of grit from the Inside of the reservoir is released When turning further clockwise the transfer openings 11 or the corresponding part of them Openings 11 in register with the passage 7, so that grit from the Storage container interior via the guide channel 15 on the feed surface of the Scatter plates 2 can reach. Due to the possibility of covering the To change openings 11 and 5 or 7 continuously, you can also change the Measure the order of magnitude of the spread material dispensed.
- a spool 10 is now provided, which to the bottom surface 19 of the bottom pan trapezoidal in cross section arranged adjacent from below and opposite this in the direction of travel or is displaceably guided perpendicular to it in a manner not shown here are in the area of the tub floor, namely the roughly horizontal one Trough bottom wall 19 in the direction of travel in front of the vertical axial center plane the screw conveyor 3 a across the transverse extent of the storage container 0 extending row of scattering openings 5 provided while from this plane seen in the direction of travel to the rear, a passage 7 is formed which a guide channel 15 can spread material on the distribution surface of the spreading plate 2.
