Abstract

APPARATUS FOR DESTROYING WEEDS, according to the invention, consists of a switch (S) transformer (TR), cascade (K) assembly for the voltage multiplication, and high voltage transformer (TR) and a feedback (PS) assembly, assemblied in a whole so that input connector (F) is attached to switch (S), output connector of which is attached to one input connector of the transformer’s (TR) primary, whose other primary end is connected to input connector (N), while the output connectors of transformer’s (TR) secondary are connected to input connectors of cascade (K) assembly whose output is connected to one input connector of the high-voltage transformer’s (TR) primary, whilst the cascade (K) assembly is through feedback (PS) assembly connected to the second input connector of the high-voltage transformer’s (TR) primary, whereas the connectors of the highvoltage transformer’s (TR) secondary are connected to the electrodes (E) which produce a strong electromagnetic field.The apparatus for destroying weeds can be designed as a portable apparatus, as well if the electrodes (E) are placed onto the carrier (30) for mounting on a hand carts, on a motocultivator, on a tractor, on truck, on a trailer or on a hauler of another vehicle on which devices apparatus for destroying weeds is also placed and from which apparatus is, through conductors, a high voltage from output connectors on apparatus, conducted to each of plurality of electrodes (E) mounted on the carrier (30).Apparatus for the destroying weeds in operation expose a plant to a strong electric field, which within plant, due of the losses, produce heat, so that the temperature of the plant increases. Increase of temperature wihin plant increase the dielectric losses in the plant also, which results in further heat rise and further rise of losses. This cumulative process takes until heat reaches the point where weed is destroyed due to electrothermal breakthrough.
