"Device, especially mobile device for distributing compost or similar grit"

The invention relates to a device, in particular a mobile device for distributing compost or similar grit agricultural land. Such a distribution of compost or similar grit has so far taken place regularly in cumbersome way and with considerable expenditure of time.

There are known vehicles of the type of trucks that have so-called wide spreaders at their rear end, which have several rotating blade sets with a vertical axis of rotation. But these wide spreaders can be used in essentially only sprinkle the driving width traveled by the vehicle. For a distribution of grit on the Fanrweg however, they are unsuitable for neighboring fields on the side.

Known mobile sprayers that can be attached to a tractor are suitable for spraying larger ones at a wide range Areas with a rain of liquid, but not for distributing solid grit such as compost or the like.

The invention is based on the task of distributing compost or similar grit through a - in particular driving

7737363 04/13/78

bares - device over the largest possible area and as continuously as possible to make possible without the need for a special additional human body work.

The invention therefore essentially consists in the fact that the device has in combination: a grit receiving area, a collecting conveyor device for removing and conveying the grit and a distribution device arranged in particular above or essentially above the collecting conveyor device and connected to the conveyor output of the same with a blower ejection device for distributing the spreading material, which is conveyed to it by the collecting conveyor device and blown out by means of blower air, to the outside. By the invention, a continuous conveying and ejection can be obtained of the introduced into the receiving space spreading material, wherein in conjunction with the Fördervorricntung - allows ⁰ Ur the spreading material the fan of the distributor device, the generation of an even solids effective outward camming Luftstrou.es.

Ia preferred embodiments of the invention, the collecting conveyor device one or more conveyor elements extending essentially over the grit receiving space, in particular conveyor belts, with a subsequent transversely arranged collecting screw and one of the conveyor element or elements

or the collecting screw supplied with the grit, which sends the grit delivered to it to the distribution device, e.g. by means of an upwardly directed discharge pipe leading to the fan-fed discharge pipe of the distributor device Conveying outlet pipe continues to convey.

In a particularly preferred embodiment of the invention is the distribution device including the one with one

Fan cooperating discharge pipe on the grit receptacle or the aggregate of the collecting conveyor device around a vertical, in particular with the axis of the Conveyor outlet pipe coinciding axis rotatably mounted. A particularly simple embodiment results here, when the distribution device by means of a plug-in pipe connection with the delivery outlet pipe of the spreading material of the distribution device Rotatably connected to the supplying centrifuge and by means of a coaxially receiving the plug-in pipe connection Turnstile with thrust bearing is supported on the lower relatively stationary part of the device.

The device according to the invention is suitably formed as an appendable to a \ tractor unit, but can also \ - be used as a stationary device - to the extent desired. The receptacle for the grit is preferably designed in the manner of a truck platform, the bottom of which is essentially formed by one or more parallel conveyor belts and at one end of which the units such as the collecting screw and sling and the distribution device arranged above are mounted.

Separate drive sources or a common drive source can be used for the rotating units to be driven. However conveyor belt, collecting volute and spin on the one hand and the blower suitably a part of the rotatably mounted distributor device forming the other hand, driven {separately.

On the chassis 10 with the running wheels 11 and a drawbar 12 for coupling to a tractor or the like. Is the e.g. receiving containers in the form of a truck bed 135 with closed at the top or in whole or in part open recording space IjJa to accommodate the preferably from above and / or from behind, e.g. in the direction of the arrow χ, the grit to be loaded, such as compost, mounted. The floor of the receptacle 13 is in the illustrated embodiment essentially formed by two parallel juxtaposed endless conveyor belts 14, which are guided at both ends of the receptacle via guide rollers 15. These can be done in any suitable manner driven by a drive 16, for example from a tractor, so that the upper belt section of the conveyor belts 14 in the direction of arrow x, promotes from back to front.

In the front part of the receptacle Γ? is a collecting snail 17 transverse to the direction of travel with a horizontal axis

stored. The screw is designed in two parts with counter-rotating partial screws 17a and 17b, such that the partial screw 17a in the direction of arrow Xp and the single screw 17b in the direction of the arrow Xp, to the vertical center plane of the device promotes.

The grit conveyed to the center in this way is transferred to a centrifuge 18, which is carried along in the longitudinal direction of the device running axis of rotation at the front end of the receiving space 13a in front of the collecting screw 17 and that of the grit picked up in the direction of the arrow x-, into a conveying outlet pipe 19 promotes. Conveyor belts 14, collecting screw and centrifuge 18 together form a collecting conveyor device S, which is mounted on the chassis 10 or in or on the receptacle 13 and with this a relatively stationary Unity forms.

The axis of the conveyor pipe 19 is at the same time the axis of rotation of the distribution device V, which essentially consists of a grit ejection pipe 21 with a supply or injector pipe 22 opening into this nozzle-like and a fan 27> conveying in the direction of arrow f, with the help of which aas from the centrifuge l8 Supplied via the delivery pipe 22

with

Spreading material in the direction of the arrow x ^ / air mixed from the discharge tube 21 is ejected. The delivery or injector pipe 22 forms with the output conveyor pipe 19 a plug-in unit 24, which can be mounted concentrically to the axis 20, with a schematically

indicated turnstile or axial support bearing 25, through which the distributor device V on the collecting conveyor device S or the receiving space Ij5 is rotatably mounted.

The collecting screw 17 and the centrifuge 18 are preferably driven by the same drive 16 that also drives the conveyor belts 14 drives. To drive the fan 23, on the other hand, is expedient a motor 26, which together with the ejection tube 21 and a control member 27 for pivoting the distributor device V about the vertical axis 20 on the collecting conveyor unit S or on the receptacle IJ or the chassis is rotatably arranged.

By turning the distribution device V around its axis of rotation, the spreading material can be ejected in any direction, the spinner 18 overflowing the grit from the relatively stationary collecting conveyor S in for example a metered amount the plug-in device 24 lying in the axis of rotation 20 under pressure from the rotatably mounted distribution device V fed and loosened with the help of the fan 22 with air and e.g. with a spray effect depending on the rotational position of the distributor device in the one determined thereby, possibly in itself continuously changing direction is ejected. By

the injector-like confluence of the delivery pipe 22 into the ejection pipe 21 supplied by the fan also become the fixed ones Substance parts of the spreading material are effective against the air flow from the fan and carried away by this air flow to the outside.
