DEVICE FOR WEEDING IN ROWS OF TILLED CROPS Russian patent published in 2024 - IPC A01B39/18 A01M21/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Device comprises L-shaped vertical rotary stand (1) with weeding knife (2), which weeds by rotating around the plants, frame (3) is made in the form of a horizontal part, with box (4) conjugated with it on one side, with a width equal to the width of the horizontal part of frame (3). On the outer side of the sides of box (4), two rods (5) are pivotally fixed, and their opposite ends are pivotally fixed on the outer side of the side surfaces of mounting box (6), mating box (4), wherein, to their internal surfaces of the front walls hinged are hydraulic cylinder rod (7) – to box (4) bottom part, hydraulic cylinder (8) housing – to mounting box (6) top part. Motor (9) is rigidly fixed via reduction gear (10) on horizontal part of frame (3). L-shaped vertical rotary stand (1) is rigidly fixed on output shaft (11) of reduction gear (10), rigidly connected to weeding knife (2), made in the form of circle arc with radius R with its conjugation through arc of circle with radius r on it ends with side blades of the same length, located with an acute angle of opening α in one plane. Cutting edge of knife (2) is located on outer surfaces of blades conjugated with inner surface of arc of circle of radius R. Control unit (12) is electrically connected to engine (9), hydraulic cylinder (8), sensor of distance to upper flange of ridge (13), sensor of tractor movement speed. Control unit (12) is configured to determine the location of plants and generate a control signal to engine (9) for processing around the plant due to a machine vision camera installed in front of the tractor.

EFFECT: increased accuracy of treatment and reduced damageability of cultivated plants.
