[0006] The frame is also equipped with an on-board industrial computer and an industrial camera, the industrial camera is connected to the on-board industrial computer, and the travel drive motor, cross slide, lifting drive, and rotating drive are electrically connected to the output end of the on-board industrial computer.

[0007] Furthermore, the travel drive motor, the cross slide, the lifting drive and the rotation drive are all driven by stepper motors.

[0008] Furthermore, the lifting drive comprises a lifting drive motor mounted on the cross slide, a horizontally arranged mounting plate is arranged below the lifting drive motor, and vertically arranged connecting plates are fixed on both sides of the mounting plate, and the connecting plates on both sides are arranged opposite to each other;

[0009] The output end of the lifting drive motor is fixedly connected to the first connecting rod, and the end of the first connecting rod away from the lifting drive motor is hinged to the second connecting rod and the third connecting rod in sequence. The end of the third connecting rod away from the second connecting rod is hinged to the connecting plate on one side of the mounting plate, and the connecting plate on the other side of the mounting plate is slidably installed on the cross slide through a vertically arranged linear module.

[0010] The beneficial effects of the utility model are as follows: when the utility model is working, the travel drive motor drives the weeding device to move forward. During the walking process, the industrial camera identifies the weed information and the position parameters of the weeds, and then combines with the cross slide and the lifting drive to drive the weeding knife to run to the weed position. Finally, the rotary drive drives the weeding knife to weed in a directional manner, thereby reducing energy consumption and damage to crops. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-4 As shown, the utility model includes a frame 1, and depth limiting wheels 2 are respectively installed on both sides of the bottom of the frame 1, and the depth limiting wheels 2 are installed on the bottom of the frame 1 through a travel drive motor 3. A cross slide 4 is installed on the frame 1, and the cross slide 4 includes longitudinal linear modules 4.1 installed on both sides of the frame, and a transverse linear module 4.2 is installed between the sliders of the longitudinal linear module 4.1. A lifting drive 5 is installed on the slider of the transverse linear module 4.2. The lifting drive 5 includes a lifting drive motor 5.1 installed on the slider of the transverse linear module 4.2, and a horizontally arranged mounting plate 5.2 is arranged below the output end of the lifting drive motor 5.1. Vertically arranged connecting plates 5.3 are respectively fixed on both sides of the mounting plate 5.2, and the connecting plates 5.3 on both sides are arranged opposite to each other.

[0016] The output end of the lowering drive motor 5.1 is fixedly connected to the first connecting rod 5.4, and the end of the first connecting rod 5.4 away from the lifting drive motor 5.1 is hinged with the second connecting rod 5.5 and the third connecting rod 5.6 in sequence. The end of the third connecting rod 5.6 away from the second connecting rod 5.5 is hinged to the connecting plate 5.3 on the side of the mounting plate close to the lifting drive motor 5.1, and the connecting plate 5.3 on the other side of the mounting plate 5.2 is slidably installed on the slider of the horizontal linear module 4.2 through a vertically arranged linear guide rail 5.4.
