[0034] Specifically, in the weeding module 201 at the upper end of the first guide frame 202, the first weeding claw 201m and the second weeding claw 201n are in a state of being away from each other, and the first weeding tooth 201a-1 and the second weeding tooth 201l-1 are loosened; in the weeding module 201 below the first guide frame 202, the first weeding tooth 201a-1 is always inserted between the corresponding two adjacent second weeding teeth 201l-1, and the second weeding tooth 201l-1 is always inserted between the corresponding two adjacent first weeding teeth When the weeding module 201 above the first guide frame 202 moves forward and rotates downward to the bottom of the first guide frame 202, the first weeding claw 201m and the second weeding claw 201n gradually move toward each other. When the weeding module 201 below the first guide frame 202 moves backward and begins to rotate toward the upper end of the first guide frame 202, the first weeding claw 201m and the corresponding second weeding claw 201n move away from each other, throwing the pulled weeds backward.
[0035] During operation, the upper weeding transmission chain 209 moves forward, and the lower weeding transmission chain 209 moves backward. The upper weeding transmission chain 209 drives the plurality of weeding modules 201 to move forward along the first guide frame 202 and the second guide frame 203, and the lower weeding transmission chain 209 drives the plurality of weeding modules 201 to move backward along the first guide frame 202 and the second guide frame 203. When the weeding module 201 moves forward to the front end arc section, it first moves forward and downward and then moves downward and backward. During the downward and backward movement, the first weeding claw 201m and The second weeding claw 201n moves towards each other, and the first claw plate 201a and the second claw plate 201l go deep into the field to shovel the weeds. When continuing to move horizontally backward, the first claw plate 201a and the second claw plate 201l are plugged together to clamp the shoveled weeds, and the first claw plate 201a and the second claw plate 201l move horizontally backward to further scrape off the weed roots. When moving to the rear of the first guide frame 202 and the second guide frame 203, the first weeding claw 201m and the second weeding claw 201n move away from each other, the weeds are thrown out, and the weed roots are not easy to directly land on the ground, further improving the weeding effect.
[0036] Specifically, one end of the two adjacent front upright plates 602 and the two adjacent rear upright plates 601 that are oppositely arranged are respectively fixedly connected with a guide rail 204, and the guide rail 204 includes an intermediate guide portion 204b, and a front guide portion 204a that extends upward and outward is fixed at the front end of the intermediate guide portion 204b, and the distance between the two adjacent front guide portions 204a gradually increases from the back to the front, and a rear guide portion 204c that extends backward and upward is fixed at the rear end of the intermediate guide portion 204b, and the distance between the two adjacent rear guide portions 204c gradually increases from the front to the back. The first weeding claw 201m and the second weeding claw 201n can slide along the opposite side of the two adjacent guide rails 204, respectively. When the first weeding claw 201m and the second weeding claw 201n slide along the corresponding two adjacent intermediate guide portions 204 b When the one side relatively set is slid, the first weeding tooth 201a-1 and the second weeding tooth 201l-1 are plugged together, and when the weeding module 201 above the first guide frame 202 and the second guide frame 203 moves from back to front and rotates downward, the first weeding claw 201m and the second weeding claw 201n are first opened and then gradually move toward each other under the action of the two adjacent front guide parts 204a, and the first claw plate 201a and the second claw plate 201l move toward each other to weed, and when continuing to move to the position of the middle guide part 204b, the first claw plate 201a and the corresponding second claw plate 201l are plugged together and clamp the weeds shoveled and move backward, and when the clamped weeds move backward to the position of the rear guide part 204c, the first claw plate 201a and the second claw plate 201l gradually move away from each other, and the weeds are thrown out.
[0037] Specifically, a first connecting rod 201b is fixedly connected between the two first weeding claws 201m in the weeding module 201, and the front and rear ends of the first connecting rod 201b extend out of the two first weeding claws 201m respectively, and the first connecting rod 201b extending out of the two first weeding claws 201m is respectively fixedly connected to the first extension rod 201e, and a second connecting rod 201i is fixedly connected between the two second weeding claws 201n in the weeding module 201, and the front and rear ends of the second connecting rod 201i extend out of the two second weeding claws 201n respectively, and the second connecting rod 201i extending out of the two second weeding claws 201n is respectively fixedly connected to the second extension rod 201h, and the first extension rod 201e is fixedly connected to the first extension rod 201h.

When the first extension rod 201e and the second extension rod 201h move downward and backward along the front guide portion 204a, the first extension rod 201e and the second extension rod 201h gradually move toward each other under the action of the first weeding claw 201m and the second weeding claw 201h respectively move backward and forward along the front guide portion 204a. The second weeding claw 201n drives the first claw plate 201a and the second claw plate 201l to move toward each other, and the first weeding tooth 201a-1 and the second weeding tooth 201l-1 continue to move toward each other after entering the ground to remove the weeds between the rows. When the first extension rod 201e and the second extension rod 201h move to the position where the middle guide part 204b is located, the first weeding tooth 201a-1 and the second weeding tooth 201l-1 are completely plugged together to clamp the weeds to be removed, and the bottom of the first weeding tooth 201a-1 and the second weeding tooth 201l-1 continue to move toward each other. It scrapes backward along the ground to further remove the unpulled grass roots. When the weeding module 201 moves to the position of the rear guide part 204c, the first extension rod 201e and the second extension rod 201h move away from each other under the action of the inter-row weeding return spring 201j, and swing upward along the first guide frame 202 and the second guide frame 203. The first claw plate 201a and the second claw plate 201l gradually loosen to throw out the clamped weeds, and the grass roots are not easily inserted into the ground, thereby improving the weeding effect.
