[0031] The adjusting mechanism 3 includes a lead screw 32. A turning handle 31 is fixedly connected to the top of the lead screw 32. A fixed disk 36 is fixedly connected to the outer wall of the frame 1. A rotating rod 35 is rotatably connected to the top of the fixed disk 36. A latch 37 is slidably connected to the inner wall of the rotating rod 35. A limiting post 38 is rotatably connected to the inner wall of the rotating rod 35. By sliding the limiting post 38 in the adjusting handle 4, the position of the adjusting handle 4 can be restricted. A weeding paddle 7 is slidably connected to the outer wall of the quick-connect mechanism 8. A protective shell 6 is fixedly connected to the bottom of the adjusting handle 4. A limiting plate 33 is fixedly connected to the outer wall of the lead screw 32. The bottom of the limiting plate 33 is slidably connected to the top of the frame 1. The inner wall of the frame 1 is rotatably connected to the outer wall of the lead screw 32. The outer wall of the lead screw 32 is threadedly connected to the inner wall of the adjusting handle 4.

[0032] The outer wall of the latch 37 is slidably connected to the inner wall of the fixed disk 36 through a limiting hole 34, and the limiting hole 34 is opened in the wall of the fixed disk 36. By inserting the latch 37 into the fixed disk 36, the positions of the fixed disk 36 and the rotating rod 35 can be restricted by the latch 37. The outer wall of the limiting post 38 is slidably connected to the inner wall of the adjusting handle 4. The quick-connect mechanism 8 includes a rotating shaft 87. A torsion spring 85 is fixedly connected to the inner wall of the rotating shaft 87. A slider 82 is slidably connected to the inner wall of the rotating shaft 87 through a sliding groove 86, and the sliding groove 86 is opened in the wall of the rotating shaft 87. A plug disk 81 is fixedly connected to the bottom of the slider 82. A plug post 83 is fixedly connected to the top of the plug disk 81.

[0033] The top of the plug disk 81 is in contact with the bottom of the rotating shaft 87. The outer wall of the rotating shaft 87 is slidably connected to the inner wall of the weeding paddle 7. One end of the torsion spring 85 away from the rotating shaft 87 is fixedly connected to a turntable 84. The bottom of the turntable 84 is inserted and connected to the top of the plug post 83. By rotating the torsion spring 85, the torsion spring 85 accumulates torsional force, so that the slider 82 is always in the positioning groove. The outer wall of the rotating shaft 87 is rotatably connected to the inner wall of the protective shell 6.

[0034] Working principle:

[0035] When in use, the operator holds the two handles of the adjusting handle 4 with both hands, and then pushes the adjusting handle 4, so that the frame 1 is driven to move by the adjusting handle 4. A pulley set 2 is provided at the bottom of the frame 1. Therefore, under the rotation of the pulley set 2, the friction between the frame 1 and the ground can be reduced. When the frame 1 moves to the weeds, by rotating the adjusting mechanism 3, the height position of the weeding paddle 7 can be changed by using the adjusting mechanism 3, so that the height of the weeding paddle 7 fits the roots of the weeds. Then the stepping motor 5 can be started, and the rotating shaft 87 on the quick-connect mechanism 8 is driven to rotate by the stepping motor 5, so that the weeding paddle 7 rotates synchronously with the stepping motor 5. Under the high-speed rotation of the weeding paddle 7, the roots of the weeds can be cut off to achieve the purpose of weeding. After a long time of weeding work, when the weeding paddle 7 is worn and the weeding efficiency becomes poor, the weeding paddle 7 can be replaced by the quick-connect mechanism 8, so as to restore the weeding efficiency of the weeding machine.

[0036] After the frame 1 moves to the weeds, first turn the throttle 31, which drives the lead screw 32 to rotate synchronously. There is a limit plate 33 fixed on the lead screw 32. Therefore, under the restriction of the limit plate 33, the position of the lead screw 32 can be restricted. During the rotation of the lead screw 32, since the lead screw 32 is threadedly connected to the adjusting handle 4, when the lead screw 32 rotates, the height position of the adjusting handle 4 changes with the rotation of the lead screw 32. After the adjusting handle 4 drives the weeding paddle 7 to fit against the root of the weeds, stop rotating the lead screw 32. It should be noted that when adjusting the height of the weeding paddle 7, the weeding paddle 7 should not be made to fit against the ground to prevent the weeding paddle 7 from hitting the ground and thus causing potential safety hazards. After the position of the weeding paddle 7 is adjusted, start the stepper motor 5, which drives the weeding paddle 7 to rotate through the stepper motor 5, so that the rope body on the weeding paddle 7 strikes against the root of the weeds during rotation, thereby removing the weeds. And there is a protective shell 6 outside the weeding paddle 7. Therefore, during the weeding process of the weeding paddle 7, the flying debris is blocked by the protective shell 6, thus preventing the debris from flying out and hitting the staff.

[0037] At the same time, by pulling out the pin 37, the pin 37 can be disengaged from locking the rotating rod 35. Then adjust the angle of the rotating rod 35, and then insert the pin 37 back into the limit hole 34 in the fixed disk 36, so that the pin 37 fixes the position of the rotating rod 35 and the fixed disk 36 again. Since the limit post 38 on the rotating rod 35 passes through the adjusting handle 4, after the angular position of the rotating rod 35 changes, the rotating rod 35 synchronously drives the adjusting handle 4 to change the angular position through the limit post 38, and then changes the position of the weeding paddle 7.

[0038] After the weeding paddle 7 has been used for a long time, the rope body on the weeding paddle 7 will be worn, which will cause the rope body to break, thereby affecting the weeding efficiency of the weeding paddle 7. The weeding paddle 7 can be quickly replaced through the quick-connection mechanism 8. Just rotate the insertion plate 81 forcefully. Drive the slider 82 to slide in the chute 86 through the insertion plate 81, so that the slider 82 slides from the positioning groove on the rotating shaft 87 into the chute 86. Then pull down the insertion plate 81, so that the insertion plate 81 drives the slider 82 and the insertion post 83 to slide out of the rotating shaft 87, so as to release the locking of the insertion plate 81 on the weeding paddle 7. Then take out the weeding paddle 7, slide the new weeding paddle 7 along the groove on the rotating shaft 87 onto the rotating shaft 87. Then align the insertion plate 81 with the bottom of the rotating shaft 87, so that the insertion post 83 contacts the turntable 84. Then rotate the insertion plate 81 so that the insertion plate 81 applies a compressive force to the torsion spring 85 through the turntable 84. Then keep the position of the insertion plate 81, align the slider 82 on the insertion plate 81 with the chute 86 and slide it into the rotating shaft 87. When the slider 82 slides to the top of the chute 86, release the holding force on the insertion plate 81, so that the insertion plate 81 can rotate but cannot fall out of the rotating shaft 87. At this time, the torsion spring 85 releases its elastic potential energy, thereby driving the insertion post 83 to rotate through the turntable 84, and then making the insertion plate 81 rotate, so that the slider 82 slides from the chute 86 into the positioning groove, so as to keep the position of the insertion plate 81, and further continuously limit the position of the weeding paddle 7.
