FIELD OF THE INVENTION The invention relates to agricultural machinery.

The aim of the invention is to increase electrical safety and processing efficiency.

Figure 1 presents the proposed device, top view; figure 2 - the working body of the device, side view; on fig.Z - the same, top view.

A device for electroprocessing of plants is mounted on the frame 1 of the tractor and contains an electrical generator 2 connected to the tractor's power shaft, connected to it by a step-up transformer 3, to the output of which is connected to one of the wires the grounding electrode 4 and to the other electrodes 5 with shields 6, by the number of machined inter-rows, fixed on the slides 7 connected to the horizontal axis 8, through connectors 9, consisting of (FIGS. 2 and 3) horizontal bushings 10 on the horizontal axis 8, vertical axis 11 chitel 12, wherein the horizontal sleeve 10 is fixedly connected with the hub 11 of vertical axis, and the vertical axis 11 itself is fastened to the end of the runner 7, and its rotation about this axis is restricted limiter 12 fixed to the sleeve 10 of horizontal axis.

The device after hitch on the tractor works as follows.

The gaps 7 are fitted with protective screens 6 with electrodes 5, corresponding to the dimensions of the inter-row spaces, and the skids 7 with connectors 9 are placed on the horizontal axis 8 along the centers of the inter-rows. The height of placement of the electrodes above the soil surface is established by moving the insulator with electrode 5 and screen 6 along the skid 7. Limiter 12 sets the allowable vibrations of screen 6 with electrode 5 in a horizontal plane depending on the straightness of the row.

The electrodes 5 and the grounding electro 4 are lowered into the aisle between the cultivated crop, the generator 2 is operated from the tractor's power take-off shaft and after the start of movement, energy is supplied through the boost transformer 3 to the ground electrode 4 and the electrodes 5. When the electrode 5 contacts Weed current from this electrode passes through the sorn and the earth to the grounding electrode 4. The passage of the current through the sorn to causes its death. The degree of damage depends almost proportionally on the magnitude of the applied voltage and the time of exposure. Cultivated plants in row and their leaves are removed by screen 6 from electrode 5 and are not affected by current. In turn, the cultivated plants orient the screens 6 with the electrode 5 in the center between the screens due to the elliptical shape of the screen 6 and the horizontal runner 7 moving due to the vertical axis 11 of the connector 9, and the horizontal axis allows the skid 7 to copy and ensure the required height of the electrode 5. The triangular cutout in front of the elliptical screen 6 and, accordingly, electrode 5 deflects weeds growing close from row to center between the rows "
