The invention relates to the control of weed vegetation due to the use of electrical energy and represents the working organ of an electro-cultivator.

The purpose of the invention is to increase the efficiency of the device and reduce energy consumption.

Figure 1 shows a device for weed control, a general view; Fig. 2 illustrates the transposition electrodes along the motion front (the numbers denote the electrode numbers in the section corresponding to the sequence number of the transformer high-voltage module.

The device contains sources of high voltage 1, made in the form of identical transformer high-voltage modules and mounted on frame 2, to which rod 4 is attached to insulators 3. Rotating sections 6 with electrodes 7 are attached to the rod by means of racks 5. plants installed electrostatic screens 8; The ground electrode 9 provides reliable contact.

Consider the work of one section of the device.

When the first electrode of section 6 contacts the weed plant, an electrical circuit closes, formed by the first terminal of the secondary winding of the transformer module 1, electrode 7, the plant through the root system, the grounding electrode 9, the second terminal of the transformer module 1,

The following options are possible. The equivalent conductivity of weeds along the front has a slight scatter (nominal value). The current is distributed evenly across the sections, the contact time is determined by the speed of movement of the section over the rows of the processed crops.

The equivalent weed conductivity along the front varies by an order of magnitude. In that

In this case, a section electrode with a higher conductivity, for example, the first electrode 7 of the first section shunts the electrodes 7 numbered one of the other sections, however, it does not affect the operation of the electrodes of adjacent sections with different unitary units, since in each section the electrodes 7 are applied to independent modules 1 When the section moves on the affected area, it falls into

zone of action of the following electrodes 7 sections. Thus, when the section moves along the row of the cultivated culture, there is a method of switching power supply sources 1 from 1 to n, where n is the number of modules 1.

corresponding to the number of electrodes 7 in the section. This achieves an increase in the time of contact with weeds and significantly improves the quality of processing of various crops with a device for

weed control.
