Agricultural machinery automatic driving steering execution mechanism

The invention relates to the technical field of agricultural machinery automatic driving, in particular to an agricultural machinery automatic driving steering execution mechanism which comprises a main positioning seat, and an adapter seat with an angle adjusting function is fixedly mounted at the bottom of the main positioning seat. According to the automatic driving steering execution mechanism for the agricultural machinery, a rotating control ring is fixedly installed on a steering wheel, a main control motor is started to push the rotating control ring to rotate left and right along a guide cylinder through a horizontal gear and an annular tooth groove, so that left-right rotation of the steering wheel is achieved, and direction control is achieved by simulating a human hand to grasp the steering wheel of an automobile; the steering wheel does not need to be disassembled during overall operation, and the connection between the upper side of the mounting disc and the main positioning seat is released by
