Actuating mechanism of agricultural picking robot

The invention discloses an agricultural picking robot executing mechanism which comprises a walking vehicle, a mechanical arm and a collecting frame, the mechanical arm and the collecting frame are installed on the walking vehicle, the tail end of the mechanical arm is connected with a picking executor, the picking executor comprises two sets of clamping rods, and the two sets of clamping rods are used for clamping and fixing the two sides of a round crop; the adsorption part is mounted between the two groups of clamping rods, and the middle part of the round crop is attracted by utilizing the suction force generated by the adsorption part; the repulsive part is installed on the outer side of the clamping part and generates certain repulsive force, and the repulsive force enables obstacles located on the two sides of a round crop to be separated from the repulsive force, and according to the executing mechanism of the agricultural picking robot, through the force in the two directions of the adsorption part a
