Agricultural device for processing on the Crop lying on the ground.

This invention relates to: an agricultural implement for processing crops lying on the ground, sit at least a Hotor arranged on a chassis, which is in a almost horizontal, slightly forward inclined plane can be set in rotation and with substantially radially protruding resilient prongs is occupied.

A major difficulty with this known per se It is advisable that the tines are combined in one operation Both cotation and translation in one on the front of the device Move slightly forward inclined plane so that the prongs tend to push into the soil. This allows them to tear off but above all the crop to be processed is through

the tines penetrating into the soil on a strong

exposed and the Grasnarj ^ o is damaged in a giant. It is well known to wind the tines at their inner end as a helical spring, so that the protruding part of the prong opposite the fastening point of the helical spring can "make a strong angular twist" This measure is not sufficient to solve the above-mentioned difficulty.

The invention creates a solution for the abovementioned difficulty, in that 1-means are arranged _; in order to set up one prong, which is exposed to a resistance during its unwinding movement, with the protruding part of the prong opposite the prong attachment.

Kach become a preferred embodiment of the invention this i-Jittel is formed by a guiding surface along which the sufficient prong is guided upwards. An evasive one According to the invention, the prong is upward, i.e. it is sprinkled from the ground, The disadvantages mentioned above can be avoided as a result of this.

The guide surface Ic ^ ^- Hn according to the invention are formed by an inclined loop fastened to the eotor, along the surface of which a protruding prong part, which resiliently yields in the Uafangsricht-ung, slides upwards.

The Exfinäxaig can be realized in a "special way in a device after a * erLdrt vorTreroffeiitlicliten other proposal -sreräeiij where the prongs are external pivot axes with the Hotor -rez-bound, which are in a plane radial to the eotor and perpendicular to the through that extend through the tine attachment, and with each hinge caciise arranged on a foot; the sink can be opened when the motor is valid.

while it counteracts the rotation of the -iotors by the centrifugal force be pressed down by the spring force. When operating the device according to this older suggestion, the tines are grounded the centrifugal force pressed forcefully against the ground, so that the above-mentioned Disadvantages also occur here.

In such a device, the invention can thereby be implemented that the pivot axis is directed obliquely backwards and downwards in relation to the direction of rotation of the rotor is that it follows the orbit described by the tip of the tine cuts, bezv /. passes in close proximity. 'Venn now in these If the tine touches the ground while rotating, it has to go in the upstream direction working friction force is a component that moves the tine upwards around the pivot axis, i.e. against the centrifugal force tried to pan. The just mentioned inclination of the pivot axis is chosen so that the residual pressure on the ground is very low.

The 3chvienkach.se is preferably the opposite of the rotary Direction of the rotor also obliquely backwards and outwards directed. The prong itself is directed essentially radially outwards, i.e. at a sharp Iangle with the pivot axis, which favors the pivoting up when pressure is applied in the circumferential direction. It is also readily admissible that the prong is inclined slightly forward in relation to the direction of rotation, which improves the effect on the crop lying in the field «,

According to another embodiment of the invention is the tine arranged at one end of a two-armed lever, the pivot of which

710055616.11.72

punki is formed by a pivot axis that is flat at right angles to the _{circumference of the motor rod end 3} eü of the Hotor, while the other arm of the lever serves as a stop and, if necessary, as a counter face, if the prong is loaded in the initial direction, it rotates Lever against the working direction of the centrifugal force so that the tine can aach & n without increasing its tension. The tine can also fly in a hissing paint onto a filing device, which also shoots the tine upwards when it is pivoted. The prong can be connected via a pivot axis with the z ^ eggniigen lever "and the part mentioned can be a fixed part of the hotor, over which the protruding prong part extends.

The straightening of the prong by twisting can also be improved with a prong with a helical spring-like winding at the inner end by the fact that the protruding prong part extends tangentially outwards from the helical winding and diagonally towards the rear opposite the direction of rotation of the rotor up to through the prong fastening going radius over extending part and a second / second practically radially outwardly extending part is composed. In comparison, a prong that extends radially outwards and straight from the helical winding increases a kinked prong according to the invention with the same angular rotation around its fastening considerably more inwards or vice versa, the kinked prong only needs a smaller angular rotation to move inwards over the same distance. so that the kinked tine is freed faster bestv. is charged lower.

which itself is rotatably received in a sleeve 11 welded to the support tube 1. The pivot axis 8 can be inserted in two pivot holes in holes of a Sinstell-plate 12 welded to the support tube 1. When the rotor is at a standstill, the tine 3 is interlaced in the two pivot positions of the pivot axis 8 by the spring 9 after the vertically upward position, but during operation the tine is held obliquely protruding downward by the centrifugal force. In the sinstellposition of the swivel axis S shown in solid lines in FIG. 2, the intermediate part k of the tine 3 is held in the unloaded operating state by the centrifugal force against or at least in close proximity via the cam disk 7 attached to the support tube 1. The tine is held in place now loaded in the circumferential direction, the intermediate part k of the tine is forced upwards along the disc 7 when it deflects, so that the tip of the tine also moves upwards and comes free from the ground or is no longer pressed against the ground by centrifugal force.

In the 3-position of the pivot axis S shown in broken lines in FIG. 2, the rearwardly evasive tine 3 <3a- is moved upwards so that its joint part h slides upwards against the support frame Λ itself. In this position, the disc 7 is out of operation and lies they are preferably within the screw socket 5- The inclined cam disk 7 described here is of course only meant as an example, the upward forcing of prongs of various kinds can be obtained by means of guide surfaces of various kinds arranged on the Hotor.

In Fig = 4, another embodiment of the invention is shown, according to which the prongs 3 arranged on a pivot axis automatically straighten up in a springy evasive manner. Hach Fig. 5, the prong 'is attached to a pivot axis 13, which is mounted in a socket 14 connected to the circular support tube the tips of the prongs 3 intersects or passes in the next height, if the prongs 3 are designed twice as shown in Fig. h , the axis should intersect the orbit of the lower prong tips. Due to the inclined position of the axis 13 is achieved that ü ± e attempts to rotate against the centrifugal force upwards about its pivot axis, the sink on a schleifenaen via the Bode Zlakaaspitse aiift.reten.de load. 15s it was found that this effect remains in sufficient extent if the central axis of the pivot axis 13 does not, exactly, intersect the Tfmlaufki-Eis described by the tine tips, but has a deviation iron TO upwards or 5 downwards than indicated in FIG. 4.
