UNMANNED WEEDING ROBOT Russian patent published in 2022 - IPC A01M21/02 A01B39/18 B25J5/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Unmanned robot-weeding machine comprises frame (1), on which control and navigation system (2), storage batteries (3), plant detection and recognition system (4) are installed, system for control of operation of cylindrical linear electric motors (9), two cylindrical linear electric motors and four wheels (5) for movement. Each wheel (5) comprises post (6) with a rotary mechanism and is driven by a separate DC motor (7) through rotating shaft (8). First cylindrical linear electric motor is located in frame (1) horizontally and includes movable stator (10) and a fixed combined armature (11) consisting of magnetic bushings (12) and non-magnetic rings (13). Second cylindrical linear electric motor is vertical, connected perpendicular to the first cylindrical linear electric motor, and includes fixed stator (14) and a movable combined armature (15) consisting of magnetic bushings (16) and non-magnetic rings (17). In the lower part of the movable combined armature (15) there is DC motor (18), which drives cutting tool (20) through shaft (19) for mechanical removal of weeds (21).

EFFECT: higher weeding quality of row and row spacing of cultivated crops from weeds, reduced damage to cultivated plants and reduced power consumption.
