By setting the first driving motor 20, the driving shaft of the first driving motor 20 rotates to drive the lead screw 11 to rotate. The rotation of the lead screw 11 causes the installation block 9 to move upward along the lead screw 11 inside the support groove 8 of the fixing plate 3. The upward movement of the installation block 9 drives the clamping plate 18 and the clamped cotton stalk to move upward, thereby pulling out the cotton stalk from the ground and achieving the effect of pulling out the cotton stalk.

[0025] Embodiment Three

[0026] Based on the above-mentioned Embodiment 1 or 2, refer to Figure 1 , Figure 2 and Figure 3, two limiting rods 15 are fixedly installed inside the supporting groove 8. Two limiting holes 14 are formed on the top surface of the mounting block 9. The outer wall surface of the limiting rod 15 is movably sleeved with the inner wall surface of the limiting hole 14. By providing the mounting block 9, when the mounting block 9 moves inside the supporting groove 8 of the storage box 5, it will move along the two limiting rods 15.

The supporting hole 12 is communicated with the supporting groove 8. The inner wall surface of the supporting hole 12 is fixedly sleeved with a bearing 13. The outer wall surface of the lead screw 11 is fixedly sleeved with the inner wall surface of the inner ring of the bearing 13. By providing the lead screw 11, when the driving shaft of the lead screw 11 rotates, it drives the inner ring of the bearing 13 to rotate. The bearing 13 can support the top end of the lead screw 11 to achieve the supporting effect on the lead screw 11. A plurality of supporting legs 7 are fixedly installed on the bottom surface of the base plate 1. Universal wheels are fixedly installed on the bottom surface of the supporting legs 7. A push handle 6 is fixedly installed on the top surface of the base plate 1. A storage box 5 is fixedly installed on the top surface of the base plate 1. By providing the push handle 6, the staff holds the push handle 6 with their hand and pushes the base plate 1 forward. When the base plate 1 moves forward, the universal wheels on the supporting legs 7 at the bottom surface of the base plate 1 roll on the ground, thereby moving the position of the base plate 1.

[0027] Working principle: Please refer to Figures 1-5 As shown, by providing the base plate 1, after the staff moves the base plate 1 to the side of the cotton stalk and pulls out the cotton stalk from the ground, there may be soil attached to the root of the cotton stalk. The staff starts the second driving motor 21. The driving shaft of the second driving motor 21 rotates inside the rotating hole 22 on the support plate 2 to drive the cam 24 to rotate. The cam 24 will rotate around the positioning column 28 on the support frame 25. The support frame 25 and the positioning column 28 can limit the rotation of the cam 24. When the tip of the cam 24 rotates to contact the side surface of the pressing plate 27, the pressing plate 27 will move forward. The forward movement of the pressing plate 27 drives the connecting block 29 to move forward along the mounting rod 30 inside the fixing groove 23 on the support plate 2 and at the same time compresses the spring 19. The forward movement of the two pressing plates 27 will squeeze the soil at the root of the cotton stalk. When the round end of the cam 24 rotates to contact the pressing plate 27, the acting force of the spring 19 causes the connecting block 29 to move backward along the mounting rod 30. The staff intermittently squeezes the soil at the root of the cotton stalk by moving the pressing plate 27 back and forth, so as to disperse the soil at the root of the cotton stalk and let it fall on the ground while pulling out the cotton stalk, achieving the effect of removing soil from the root of the cotton stalk, avoiding the need for the staff to process the soil attached to the root of the cotton stalk again later, and facilitating the staff to pull out the cotton stalk.

[0028] Through the provided substrate 1, the staff move the substrate 1 and the fixed plate 3 so that the cotton stalk is located between the two clamping plates 18 on the fixed plate 3. The staff activate the electric push rod 17, and the telescopic shaft of the electric push rod 17 moves forward to drive the clamping plate 18 to move forward until the inside of the clamping plate 18 abuts against the outer wall of the cotton stalk, thereby clamping the cotton stalk. Through the provided first driving motor 20, the driving shaft of the first driving motor 20 rotates to drive the lead screw 11 to rotate. The rotation of the lead screw 11 causes the mounting block 9 to move upward along the lead screw 11 inside the support groove 8 on the fixed plate 3. The upward movement of the mounting block 9 drives the clamping plate 18 and the clamped cotton stalk to move upward, thereby pulling the cotton stalk out of the ground, achieving the effect of pulling the cotton stalk.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
