(54) DEVICE FOR CLEANING AGRICULTURAL

PLANTS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, mainly to devices for harvesting agricultural plants.

It is known a device comprising an intermix, a vehicle frame, on which a directional device is mounted, a shear device and a transverse conveyor. The cutting device is made in the form of a segment-finger apparatus, which includes a finger bar with fingers and inserts, knife strips with segments and a knife head. Supporting shoes with steel rails are attached to the ends of the finger bar. A board is pivotally attached to the outer shoe.

In the process, the stems are divided by fingers into small portions and enter between the adjacent fingers. The stems are then deviated by segments to the fingers and cut by cutting pairs. Cut plants are laid on the floor behind the recess of its apparatus 1.

This device has limited performance since. when increasing the speed of movement, the finger bar will begin to press the plants and the segmental finger machine will not have time to perform the cutting operation. The speed of harvesting depends on the speed of movement of the device and can be increased only up to a certain limit, after which the process of cutting agricultural plants will not be provided.

The closest technical solution to the invention is the device

10 for harvesting agricultural plants, including a cutting tool body located under the guiding device, made in the form of two closed and mirrored gripping elements with a drive from the vehicle, having in the direction of the device, respectively, a horizontal section and a section located angle to the last 2.

A disadvantage of the known device is its low productivity.

Claims (4)

The aim of the invention is to increase productivity. The goal is achieved by the fact that the cutting tool body is located in the zone of the horizontal section of the gripping elements, and each of them is made in the form of a double hinge chain, the latter being equipped with spring-loaded plates and connected to the vehicle by a rigid kinematic link. Moreover, the cutting working body is made in the form of circular knives with drive. Also, the cutting tool body can be made in the form of two endless chains with cutting plates and a drive arranged parallel to the horizontal section of the chain, each of which is placed under the respective gripping element. And the cutting plates can be made in the form of drive circular knives. FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 shows an embodiment of the cutting device; in fig. 4 shows an embodiment of the cutting device. The device contains. the frame 1 moved by the vehicle, on which the guide device 2 is mounted, the cutting tool body 3 and the transverse conveyor 4. The guide device 2 is made in the form of two infinite and arranged as a mirror image of double hinge plate chains having two sections A and B, one of which (A) is located horizontally, and the other (B) is located at an angle to this section and above the cross conveyor 4. At the same time, both chains are equipped with spring-loaded plates 5 and are made with rigid kinematic connection yu 6 with the vehicle drive 7. The kinematic connection of the chains with the drive 7, made in the form of a power take-off shaft, is carried out by means of gear-chain gears. The gear ratio provides a speed parallel to the horizontal section of chains equal to the speed of the vehicle, but the opposite direction. A horizontal stretch of chains has a forward converging stretch of two chains, which directs grass stalks to the channel of a parallel stretch of two chains. The frame 1 is mounted on the frame 1. The cutting tool body is made in the form of forcibly rotating disk knives, which are located under the horizontal section A of the chains. The rotation drive of the circular knives can be both independently and from the vehicle power shaft. In the embodiment of the mower, the cutting tool may be made in the form of two closed chains 9 mounted as a mirror image, equipped with the cutting plates 10 and connected to the vehicle drive with a rigid kinematic link. The gear ratio ensures the speed of the chains 9 in the parallel section is somewhat higher than that of the chains of the guide device 2. In another embodiment of the mower, the cutting device can be made as a mirror image of two closed converging chains 9 connected to a rigid kinematic vehicle drive connected and equipped with forcibly rotating disk knives 11. The rotation of the disk knives 11 can be driven, for example, by means of flexible shafts connected to the selection shaft m generality. The device can be made mnogoruchevym. The device works as follows. The vehicle moves the device in front of itself across the field with cultivated agricultural plants. The chains have a continuous movement from the drive 7 of the vehicle. In the parallel horizontal section A, their speed is equal to the speed of the vehicle, but opposite to it, so that the speed of their movement relative to the plants is almost zero. The stems are guided by converging sections of chains into a channel parallel to a horizontal section A, where they are compressed with the help of chains and clamps 5 into a bundle which is in a tensioned state. The beam is captured at zero speed of the chains relative to the stalks, which creates favorable dynamic conditions for their clamping. As the device moves, the gripped tensioned beam hits the rotating disk knives that cut the stems. The cut stems are moved by chains along the inclined section B upwards to the transverse conveyor 4. At the section of divergence of the chains, the stems fall into the transverse conveyor 4, which directs them either to the rolls or to the car body. When chain constructions 9 (Figs. 3 and 4) are used as pruning devices, the cutting of the stems occurs on a certain trajectory equal to the length of the adjacent parallel section of these chains, which makes it possible to improve the cutting quality of agricultural plants. The use of the proposed mower allows for an increase in productivity due to the fact that such a design allows in principle to significantly increase the transport speed of its movement without compromising the quality of harvesting.
