The invention relates to devices for chopping up rows of plants, in particular in sugar beet growing, with knife stars rolling on the ground without an additional drive, which can be rotated on axes are stored, which are inclined to the direction of travel, and the knife stars from a hub body exist with radial knife handles and knives attached at the end that extend in the circumferential direction protrude from the knife handle and have protruding cutting edges in the radial direction. Lead at work the knives rolling on the floor make cuts in an axially parallel direction and cut corresponding ones Gaps in the row of plants.

Hacking devices are known whose knife stars are motor-driven or their drive obtained by special spade wheels. These devices have the disadvantage of being more expensive for the external drive and in general that the fast moving knives with the floor blocks damage the remaining plants and disrupt their growth.

There are also known chopping stars without external drive, those with knife disks or wide disk-shaped Work with knives that are approximately perpendicular to the ground surface during the cut and scraping the soil with the little plants to be hacked in front of you and out of the row of plants vacate. There is no cutting, but rather a tearing and scraping way of working. This inevitably increases the standing surface of the neighboring plants that should not be hacked relaxed. The plants are so badly affected that you only need several Days after work you can reliably determine how many plants are recovering and continuing to grow will. With these well-known devices, you cannot tell after work whether the desired hacking result has been achieved or whether damage has been caused to the crop, that are irreparable.

There are also knife stars with knife arms welded to the knife hub in pairs known, the neighboring knives at a correspondingly small distance from each other by their width effect also destroy the plants between them. The knives cut through one at a time the rows of plants and are not adjustable in their working width. It is also known to have two knife stars on the same drive shaft spaced one behind the other, with them at work rigidly connected to each other, but can be adjusted relative to each other by certain angles of rotation.

the knives of the second star in the rows of plants cause interfaces, wholly or partially coincide with the interfaces of the front star, so that narrower or wider clearing points can be generated. The knives perform the cutting process completely independently of one another and hit the same interface with a time lag, so that the with great speed driven knife their influence damaging the neighboring protected areas Exercise twice in a row at a short distance and the entire plant population is profoundly damaged will.

To avoid these disadvantages, angle knives known per se with in radial direction advanced cutting and protruding from the knife handles in the circumferential direction Arranged knife legs, according to the invention facing each other in pairs and so arranged are that they are approximately parallel to the ground surface during the cutting process and their working width partially cover. Each pair of knives releases a coherent one through a common separating cut Soil block out of the row of plants. The strip of soil to be cleared is on all sides, both from the subsoil and from the side detached from the remaining floor blocks by separating cuts, in which the protruding Move knife legs along their cut surfaces through the ground. So there is a clean cut that does not shake the soil blocks and the remaining plants influenced. The farmer can immediately determine with certainty how many plants will remain and whether he has to change the gap width if necessary.

According to the invention it is also provided that the hub body of the knife star in a known per se Way consists of two coaxial hub disks, which continuously adjust the block width can be rotated against each other.

F i g. 1 shows the tool rail of a chopping device with one of the chopping tools arranged on it. The other frame parts of the device and further interlocking tools are not shown because this is not essential for the conception of the invention is. F i g. 2 shows a. Hacking tool, the hub body of which consists of two with radial knife handles occupied hub disks, whereby only two of the eleven pairs of knives are drawn. F i g. 3 shows a Pair of knives when cutting a gap in the row of plants.

The fastening bracket 2 is screwed to the tool rail 1 of the hacking device by means of the screws 3. The fastening bracket carries the joint 4 for the pivot arm 5 lying in the direction of travel, at the rear end of which the axis 6, which is inclined to the direction of travel, is seated. The chopping tool 7 is freely rotatably mounted on this. The swivel arm 5 can be swiveled in a vertical plane, so that the chopping tool always rests on the surface of the ground while working. A rigid arm 8 with the draft limiter screw 9, on which the swivel arm rests when the tool rail 1 is lifted, is seated on the fastening block 2.

The chopping tool 7 consists of a front hub disk 10 and a rear hub disk 11, each of which is studded with eleven radial knife handles 13. The rear hub disc is on the Axis 6 is freely rotatable. In the front hub disc 10 there are two studs 14, which reach through slots 1 $ in the rear hub disc. The Arbelt has both hub washers firmly connected to one another by means of the screws 14. After loosening the nuts 16, the Hub disks are rotated against each other, as far as this allows the length of the contactors IS.

On the knife handles 13 üind the protractor 17 attached, the adjacent legs have protruding cutting edges and their protruding legs 18 on the knife handles of the rear hub disk in arrow direction, on which the front hub disk are directed against the arrow. During the forward movement of the chopping device, the chopping tool rolls off the body, with the protractor making cuts parallel to the axis 6 through the row of plants.

Those arranged on the knife handles of the front hub disk move in the same direction Support runners 19, each of which precedes a pair of knives and on which the chopping tool rests supported on the ground.

After loosening the nuts 16, the two hub disks can be rotated against each other, see above that the cutting widths of the protractors of a pair of knives overlap more or less and the width of the gap to be cut in the row of plants is regulated.

Claims (2)

Patent claims: 1. Device for chopping up rows of plants with axes inclined to the direction of travel freely rotatable knife stars that roll on the floor without an additional drive, consisting of a hub body with radial knife handles and attached at the end Protractor with cutting edges that are pulled forward in the radial direction and in the circumferential direction protruding knife legs, characterized in that the knife handles (13) protruding knife legs (18) are facing each other in pairs during the cutting process stand approximately parallel to the ground surface and partially vary in their working width cover, so that each pair of knives through a common separating cut a contiguous Detaches soil block from the row of plants. 2. Device for chopping rows of plants according to claim 1, characterized in that each hub body (6) in a manner known per se from two coaxial hub disks (10, 11) exists, which are continuously rotated against each other for the purpose of adjusting the block width can.
