DUPLEX ELECTRICAL SHOCK-EXCITATION CULTIVATOR Russian patent published in 2016 - IPC A01B1/00 A01M21/04 

FIELD: electricity.

SUBSTANCE: invention relates to high-frequency equipment and may be used in agriculture for the removal of weed vegetation, pruning as well as the use of technologies related to the impact of electric current on vegetation. A duplex electrical cultivator comprises a power supply source coupled by its output to an input of the first electronic commutator switch, a clock generator coupled by its output to control inputs of the first and third electronic commutator switches, a capacitive storage coupled by its first output to an output of the first electronic commutator switch and an input of the second electronic commutator switch, a pulse transformer connected by the first output of its primary winding to an output of the second electronic commutator switch, an active electrode coupled to the first output of a pulse transformer secondary winding, an admittance analyzer coupled by its input to the second output of the secondary winding of the pulse transformer coupled in its turn to an earthed electrode and by its control output connected to a control input of the second electronic commutator switch. In the duplex electric cultivator there is an additional pilot winding placed directly at the pulse transformer and current setting device coupled by its output to an input of the third key, which output is coupled to the first output of a pilot winding. The second outputs of the power supply source, capacitive storage, primary and pilot windings of the pulse transformer are coupled to the common wire.

EFFECT: simplified design, high efficiency factor, wide range of application spheres and expanded range of equipment for the removal of weed vegetation, pruning as well as the use of technologies related to the impact of electric current on vegetation.
