G-device for pruning bushes

The invention relates to a device that can be detachably attached to tractor units, tractors and the like by means of a holding device Device for the mechanical removal of excessive shoots from agricultural row crops, especially // stick in.

Especially in the case of V / one-way blocks, the «axis period of need, excessive foliage including removing young shoots so that the strength of the soil primarily benefits the grapes comes and the latter not through the Senate's work Foliage are deprived of direct sunlight. Las removal of the excess foliage happened in usually by hand and required, especially since this .work

Jis is known for the pruning of vines to simplify that per se known, motor-driven hedge trimmers on a frame on one i'raktor were attached, which drove along the vines to be pruned The cutting width, i.e. the distance between the better known ones Hedge cutting is very small, however, as it generally corresponds to the width of a knife. With large-leaved This leads to the fact that leaves that are unfavorably positioned with regard to the knife are not separated from the vines, but only cut in or pushed aside entirely. Furthermore, they put in between The narrow spaces between the open knives tend to be full of foliage, which in turn causes the i / is considerably worsened in its operation.

The object of the present invention is aaher, under umgenun.j the above mentioned ι <eighth parts a device to create a complete separation of even the largest leaves from bushes, hedges and especially vines guaranteed. »Care should also be taken to ensure that

record movements »furthermore" it is ensured that no sprouts get caught in the "chain links, because the cutting chains are protected between the extended Grehäüsewandteile.

Furthermore, it has proven to be expedient to pivot the housing with the vertically circulating chain so that inclined cut surfaces can be adjusted. \ This adjustment is especially important if the fruit set of a vine is not strong uniformly distributed over the height, but, as is often the ü'all, in the lower ranges cantilevered than in "the upper regions. Even when trimming In hedges, it is often advantageous to place the cut surface at a slight angle for side trimming.

Purely the operation of the device according to the invention it has also proven to be advantageous that the approximately vertically rotating cutting chain on its working side down and the horizontally circulating cutting chain runs outwards on their working side. This further reduces the risk of sprouts collecting and sticking to the cutting device.

To prevent the cutting chains from entering the housing sprout parts will not be guided, it has sicn Proven to be beneficial to attach an additional fixed knife to the inlet.

The two cutting chains are driven appropriately through a single iüotor over one through an additional pulley-guided drive belt. " -Uiese type of drive is characterized by extremely low Manufacturing costs.

In a technically more elegant design, the two cutting chains via two drive belts with one Angular gear connected, which is driven by the Jiotor,

The «drive of a second one arranged in mirror image Device can expediently via a cardan shaft or, if the second device for .adaptation to the changing Distance between hedges and rows of vines, adjustable in its position is done via a telescopic cardan shaft, so that only one drive motor is required for both devices is.

Jis has proven to be a particularly advantageous solution to use a hydraulic motor as the drive motor. Such a hydraulic motor only needs to To be connected to the hydraulic pump already installed in most tractors.

The device according to the invention consists of an approximately horizontal housing 1 and an approximately vertical housing 2. Both housings are connected via connecting plates 3 * 4 and a hinge 5 pivotable with each other tied together. Two chain wheels 10, 11 and 13, 14 are mounted in each housing, via which a cutting chain 6 or running around.

Each cutting chain 6 or 7 points in the radial direction protruding cutting edges 8. These cutting edges 8 are integrally connected in the embodiment shown with the tabs of the cutting chain 7 and 8, respectively beveled on the face in the upright direction.

furthermore, there are fixed cutting edges on each housing 1, 2 9 and at the outer ends 1, 2 additional knives 24 attached

The cutting chains 6 and 7 are driven by pulleys 12 and 1-5 on the shaft of the sprocket 11 and 14 are attached. The pulleys 12, 15 are driven by the i & otor 17 via the drive belt 27. In order to guide the drive belt, it also runs over a pulley that is inclined on the axis 28 16.

The drive motor 17 is attached via the on the connecting plate 3 attached pipe section 18 and the holder 19 · To change the belt tension ^ · and to Adjustment of an angular position of the drive motor 17 is the holder 1: 9 rotatable and displaceable in the pipe section 18 is arranged and is via clamping screws held in his position.

At the. In operation of the device according to the invention, the sprouts to be removed are clamped and sheared between the circumferential cutting edges 8 and the fixed cutting edges 9. Since a stripe of the movable 'cutting edges S is to be prevented at denfeststehenden Sehneidkanten 9 owing to the check resultant wear and jamming of the cutting edges must be absolutely excluded, it is necessary to' ä between the two cutting edges to provide a certain play. In the embodiment shown, this play is given by the thickness of the protruding v / and parts of the housing 1, 2? see figure 4
