[0037] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0038] Reference Figure 1-8 As shown, a mechanical weeding device comprises:

[0039] A workbench 108, wherein rollers 120 are installed at four corners of the bottom of the workbench 108;

[0040] A weed control mechanism 200, which is disposed on the front side of the upper surface of the workbench 108, and is used for lifting and cutting weeds. The weed control mechanism 200 includes two vertical guide rails 201, and a clamping groove 211 is provided on the rear side of the vertical guide rails 201. The vertical guide rails 201 are slidably connected to a lifting plate 400 through the clamping groove 211;

[0041] Reference Figure 6 , Figure 7 and Figure 8 , at least one cutting assembly 300, the cutting assembly 300 is symmetrically arranged on both sides of the upper surface of the workbench 108, the cutting assembly 300 is used to cut weeds, the cutting assembly 300 includes at least one fixed rod 308, a support rod 307 and a cutting control motor 306, the top of the fixed rod 308 is fixedly connected to a guide beam 301, the bottom of the guide beam 301 is provided with a T-shaped groove, a moving rack 302 is slidably connected in the T-shaped groove, the bottom of the moving rack 302 is fixedly connected to two hanging plates 309, the bottom of the hanging plate 309 is fixedly connected to a moving groove 316, the moving groove 316 is slidably connected to a moving block 317, the moving groove 316 An active rod 315 is fixedly connected to the output end, and the end of the active rod 315 is rotatably connected to the moving block 317. The left end of the moving slot 316 is fixedly connected to the insertion rod 305. A fixed arm 314 is fixedly connected to the left side of the guide beam 301. The left end of the fixed arm 314 is rotatably connected to the rotating shaft 303. The bottom end of the rotating shaft 303 is fixedly connected to the transmission gear 304. The top of the rotating shaft 303 is fixedly connected to the driving rod 310. The top of the front end of the driving rod 310 is fixedly connected to the movable shaft 311. The top of the support rod 307 is rotatably connected to the cutting knife 313. A cutting control groove 312 is opened through the rear side of the cutting knife 313, and the movable shaft 311 abuts against the cutting control groove 312.

[0042] When in use, the cutting control motor 306 operates to drive the active rod 315 to rotate, so that the moving groove 316 moves along the guide beam 301, thereby driving the moving rack 302 to reciprocate on the guide beam 301, and the moving block 317 will cooperate with the rotation of the active rod 315 and slide accordingly in the moving groove 316. The reciprocating motion of the moving rack 302 will drive the transmission gear 304 to rotate, and then drive the rotating shaft 303 to rotate, so that the driving rod 310 is rotated, and the movable shaft 311 at the top of the driving rod 310 slides in the cutting control groove 312, so that the cutting knife 313 rotates with the support rod 307 as the axis. Since the rotation of the driving rod 310 is reciprocating, the cutting knife 313 will reciprocate and cut repeatedly;

[0043] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 At least one lifting plate 400, the lifting plate 400 is installed at the rear side of the vertical guide rail 201, the lifting plate 400 is used to assist in lifting the weeds, a horizontal tie rod 203 is fixedly connected between the two lifting plates 400, a connecting rod 205 is fixedly connected to the left side of the right lifting plate 400, a lower clamping claw 207 is fixedly connected to the left end of the connecting rod 205, an upper clamping claw 206 is slidably connected to the left side surface of the horizontal tie rod 203, and the lower surface of the upper clamping claw 206 abuts against the upper surface of the lower clamping claw 207;

[0044] The upper clamping jaw 206 and the lower clamping jaw 207 clamp and lift the weeds in the following manner:

[0045] First, the whole device is pushed forward, and the weeds enter the gap between the upper clamping jaw 206 and the lower clamping jaw 207. The upper clamping jaw 206 and the lower clamping jaw 207 are slightly staggered. Under the control of the cutting control motor 306, the insertion rod 305 will reciprocate back and forth, but the height of the insertion rod 305 remains unchanged. When the insertion rod 305 moves in the oblique guide groove 407, the lifting plate 400 will descend and compress the lifting spring 209. When the insertion rod 305 approaches the top of the oblique guide groove 407, the state of the upper clamping jaw 206 and the lower clamping jaw 207 is as follows: Figure 3As shown, when the insertion rod 305 moves to the top end of the inclined guide groove 407, the insertion rod 305 also reaches the limit point of reciprocating motion and begins to turn back. The lifting spring 209 releases its elastic force, the lifting plate 400 rises, and is blocked by the top of the vertical guide rail 201. At this time, the insertion rod 305 is exactly at the same height as the horizontal guide groove 402. The lifting plate 400 rises, driving the upper clamping jaw 206 and the lower clamping jaw 207 to rise. The lower clamping jaw 207 rises vertically, and the upper clamping jaw 206 rises along the inclined guide rod 202, so that it will clamp the bottom of the weeds with the lower clamping jaw 207 and pull them out, and they will be cut off by the cutting knife 313. After that, the insertion rod 305 moves in the opposite direction and moves along the horizontal The guide groove 402 moves and compresses the return spring 405, causing the trapezoidal block 406 to descend, thereby passing through the transverse guide groove 402, and the insertion rod 305 continues to move outward until it reaches the turning point and returns to the right end of the transverse guide groove 402. The left and right sides of the trapezoidal block 406 are both inclined slopes, and the right side is approximately vertical, but a downward force can still be applied through the right slope. The return spring 405 is more difficult to compress than the lifting spring 209. Therefore, the insertion rod 305 causes the lifting plate 400 to descend and move into the inclined guide groove 407. The upper clamp 206 and the lower clamp 207 descend again, starting the cycle, and the grass roots clamped by the upper clamp 206 and the lower clamp 207 will also fall.
