The invention relates to the field of agricultural robots, in particular to an eight-claw actuating mechanism for a weeding
robot, which comprises a shell, a rail changing sliding block
system, a main shaft turntable
system, and eight sets of stick bite shaft systems, wherein the stick bite shaft
system rotates along with the main shaft turntable system, and the rail changing sliding block overcomes a compression spring and is lift up under the action of an upward external force so as to connect an upper side rail and a lower side rail. Every time one set of the stick bite shaft system rotates to one side of a
plant row, the shaft system drives a rotating shaft to move downwards under the action of the
rail pressure, and rotates under the limiting actions of a sleeve guide rail and a limit pin which are connected with the turntable system simultaneously, so that the stick bite externally extends into in-row plants to finish weeding motions. The eight-claw actuating mechanism has the advantages of controlling a plurality of sets of the stick bites to extend to the outside to perform
plant inter-row weeding simultaneously and ensuring the
coverage factor of inter-
plant intervals. Besides, the eight-claw actuating mechanism has the advantages of continuous weeding motions, simple and flexible operation, and convenience for the weeding
robot control and manipulate.
