DEVICE FOR MAGNETIC-PULSE TREATMENT OF DWARF PLANTS Russian patent published in 2009 - IPC A01G7/04 

FIELD: agriculture.

SUBSTANCE: device contains a high-clearance tractor, on-board electric power supply, automatic coupler with a hydraulic lift and a flat inductor. The inductor coil is in form of two differently directed spirals the ends of which are connected. The inductor is connected by the ends of its coils to the first output of the current pulse generator and placed horizontally above the soil on opposite sides of a dielectric panel. The panel is attached to a frame, mounted on the hydraulic lift with possibility of changing its height and fixation. On the frame along its longitudinal axis in front of the inductor there is quasi-monochromatic light emitter. The emitter is made on a dielectric substrate in form of a flat rectangular matrix from semiconductor lasers. Pulses of coherent light radiation with a defined wavelength of the light emitter are directed downwards against the direction of motion of the high-clearance tractor at an acute angle to the vertical axis with possibility of its changing and fixation. On the frame on two sides of the centre of the flat inductor perpendicular the horizontal plane, two series-connected Helmholtz coils are coaxially placed. The Helmholtz coils together with the flat inductor above and outer sidewalls are closed by a screen made from soft magnetic material. The transverse horizontal axis of symmetry of the flat inductor and the vertical axis of symmetry of the Helmholtz coils are mutually perpendicular and lie in the same vertical plane. The distance on the axis of symmetry of the Helmholtz coils in the vertical plane from the centre line of the thickness of the flat inductor to the centre of the Helmholtz coils is equal to half the length of their average radius. The distance between the screen from soft magnetic material and the centre line of the thickness of Helmoholtz coils is equal to a tenth of the length of their average radius. The leads of the Helmholtz coils are connected to the second output of the current pulse generator, connected through an inverter to the on-board electric power supply. The third output of the current pulse generator is connected to the quasi-monochromatic light emitter. The current pulse generator and the inverter are mounted on the frame on both sides of the light emitter.

EFFECT: device allows for protection of the operator from electromagnetic radiation of the inductor when treating plants, and carry out plant treatment under production conditions.
