The invention relates to agriculture, in particular, to technology and devices destruction of weeds without using chemicals electrophysical methods, including impacts on plants high voltage current.

A device of the destruction of weeds, including mounted on the traction mobile movable unit power source, a carrier frame with the placed on insulating posts section of the working bodies located in front of the traction mobile rolling unit [A.G. Ban, A. Dontsov and A.A. Starchenko Device for destroying weeds, As the USSR №1692471 A1 class. AM 21/00 publ. 23.11.91. Bull. No. 43]. The disadvantage of this technical solution is complex circuit implementation and the significant weight of the equipment installed on the traction mobile mobile unit.

Closest to the proposed device are of weed control, including the source of electricity, as well as working bodies [A.A. Bags and V.G. Lyapin Method of weed control and the device for its implementation, As the USSR №974946 AV 47/00 publ. 23.11.82. Bull. No. 43.]. The power source is installed on the traction mobile movable unit and consists of a three-phase generator frequency, driven from the shaft m is snasti traction mobile rolling unit, and three-phase high voltage transformer. A disadvantage of the known device for the destruction of weeds is that on plants affected by high voltage current frequency of 50 Hz, the shape of the curve which is relatively flat front rise. It is known that more effectively destroy weeds provide impact with steep front rise. In addition, at frequency of 50 Hz impedance plant tissue is large, resulting in a reduced current value impacts passing through the weeds, which reduces device performance due to the need to increase the processing time of weed plants. As the bulk of the power source (typically, this is a synchronous generator) significant, there are unproductive losses of fuel and energy to move the power source on cultivated land as well as for losses in the shaft PTO traction mobile rolling unit is used to drive a synchronous generator power source. At the same time increases the pressure on the ground traction mobile rolling unit and increases its degradation from the action of the wheel Assembly.

The task of the invention is to increase the efficiency of destruction of weeds, reducing negativnyh impacts on soil from the wheels of the traction vehicle areagreat when performing agroprocessors, reducing waste of energy and fuel when performing agroprocessors.

In use of the present invention, the efficiency of destruction of weeds will increase processing times will be reduced, the environmental conditions in the area of operation of the device will improve energy consumption and fuel when performing agroprocessed will be reduced.

The above technical result is achieved by the fact that in the proposed device for the destruction of weeds, containing a power source mounted on the traction mobile movable Assembly working bodies, the power source is implemented as a resonant power supply system includes a primary power supply, inverter, resonant transformer, and the power source is placed stationary in the immediate vicinity of cultivated land, and the structure of the device is entered odnoprovodnoi transmission line, with the output of a source of electricity connected to the input of odnoprovodnoi transmission line, the output of which is connected to the input electrode section with the working bodies, vascular plants affected by variables an electric current of a frequency of 10-20 kHz when the voltage of 10-30 kV.

The essence of the invention is illustrated by the drawing is m, which shows the General diagram of the device for the destruction of weeds listed devices destruction of weeds (figure 1).

Device for destroying weeds posted on traction mobile mobile unit 1 and consists of a power source 2, odnoprovodnoi the supply line 3, frame 4, is installed in front of the traction mobile rolling unit 1 during its movement. On the base frame 4 is placed electrode section 5 working bodies 6, which are mounted on the carrier frame 4 by means of an insulating racks 7. The power source 2 includes a primary power supply 8, the frequency Converter 9, the resonant transformer 10. Mobile the mobile unit 1 is moved on cultivated land 11 on which the weeds are designated position 12.

The output of the power source 2 is connected to the input odnoprovodnoi transmission line 3, the output of which is connected to the input electrode section 5 working bodies 6.

The device operates as follows.

In the normal mode of operation from the primary source of supply of electrical energy through a frequency Converter 9, the resonant transformer 10 is supplied in odnoprovodnoi the power supply line 3, and then at the electrode section 5 of the working bodies 6. When motion is mobile rolling unit 1 on cultivated land 11 weed plants 12 contact working bodies 6 and are electrophysical effects of high voltage high frequency. As a result of these influences weed plants die 12.

As a power source device for destroying weeds use a resonant electrical system with odnoprovodnoi line voltage 10-30 kV, the resonant frequency of 10-20 kHz. One of the main advantages of the resonant power supply systems is the possibility of using for power transmission cable with a minimum cross-section. However, losses in the power cable of the power supply are practically absent [Strebkov D.S., A.I. Nekrasov Resonant modes of transmission and use of electrical energy. - M.: viesh, 2008-352 C.]. Odnoprovodnoi line 3 are in the form ultra thin cable, or a conductive channel in the air, formed by electron or laser beam. Moreover, the use of contactless transfer of electric energy through the air gap between the bottom of the traction mobile rolling unit 1 and odnoprovodnoi line 3 when laying the last in the soil of cultivated land 11.

Impact on plants current frequency of 10-20 kHz increases the effectiveness of their destruction and reduces the duration of manufacturing processes, because the front rise impacts steeper and their dynamics harder impedance R is stuteley tissue weeds below.

Device for destroying weeds, containing a power source mounted on the traction mobile movable Assembly working bodies, characterized in that the power source is implemented as a resonant power supply system includes a primary power supply, inverter, resonant transformer, and the power source is placed stationary in the immediate vicinity of cultivated land, and the structure of the device is entered odnoprovodnoi transmission line, with the output of a source of electricity connected to the input of odnoprovodnoi transmission line, the output of which is connected to the input electrode section with the working bodies, vascular plants affected by an alternating electric current of a frequency of 10-20 kHz when the voltage of 10-30 kV.
