WORKING ELEMENT OF AUTONOMOUS ROBOTIC COMPLEX FOR SELECTIVE CONTROL OF WEEDS Russian patent published in 2020 - IPC A01C23/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Working element of the autonomous robotic complex for targeted weed control contains a frame on which a working element in the form of drill (6), a cylindrical reduction gear (2) and pipe (7) of chemicals supply are fixed. Working element is equipped with housing (1) with motor and gearbox (2) arranged in it. Small gear (4) of gearbox (2) is rigidly fixed on drive shaft (3) of electric motor in engagement with large gear (5) with decreasing gear ratio. Gears (4 and 5) are made of high-strength nylon. In the center of large gear (5) there is drill (6) with through channel (7) of pesticides supply. Drill (6) is equipped with detachable screw nozzle (8) arranged at its end and having sieving angle of 20–90°, and with bushing (9) installed above the nozzle with possibility of displacement along vertical and made with two arched blades (10) with sharpening, located at acute angle to soil surface, width of blade (10) is 5–10 mm, length is 10–20 mm. Drill (6) is connected to pipe (11) of pesticides supply by the upper part. Length of the working part of drill bit (6) is at least not less than average depth of processing of the root system of weeds. Ratio of the diameter of channel (7) to the diameter of drill (6) is 1:2.

EFFECT: higher quality of weed control, simplified design.
