[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3The utility model provides an embodiment: a rotary tiller blade depth adjustment structure of a rotary tiller, comprising a fixed frame 1, a rotating column 2 is arranged on the inner wall of the fixed frame 1, a rotating rod 3 is rotatably connected inside the rotating column 2, a toothed disc 4 is fixedly connected to the outer wall of the rotating rod 3, the outer wall of the toothed disc 4 is rotatably connected to the inside of the rotating column 2, a rotating shaft 5 is rotatably connected to the inside of the rotating column 2, a gear 6 is fixedly connected to the outer wall of the rotating shaft 5, the gear 6 is meshed with the toothed disc 4, a worm 7 is fixedly connected to the outer wall of the rotating shaft 5, a worm wheel 8 is rotatably connected to the inside of the rotating column 2, the worm wheel 8 is meshed with the worm 7, a fixed block 9 is fixedly connected to the bottom of the worm wheel 8, a threaded rod 10 is threadedly connected to the inside of the fixed block 9, the outer wall of the threaded rod 10 is rotatably connected to the inside of the rotating column 2, a tool 11 is rotatably connected to the top of the threaded rod 10, the outer wall of the tool 11 is slidably connected to the inside of the rotating column 2, and a protective component is arranged on the outer wall of the fixed frame 1;

[0025] Specifically, the entire device is first started by rotating the rotating rod 3. The rotation of the rotating rod 3 drives the toothed disc 4 to rotate inside the rotating column 2. In this process, since the toothed disc 4 is meshed with the gear 6, the gear 6 moves with the rotation of the toothed disc 4. Next, the movement of the gear 6 will drive the rotating shaft 5 to rotate inside the rotating column 2 through its connection with the rotating shaft 5, and will transmit the rotation energy of the gear 6 to the worm 7. When the worm 7 rotates, it will mesh with the worm wheel 8, so that the worm wheel 8 can rotate with the rotation of the worm 7. Finally, the rotation of the worm wheel 8 will drive the fixed block 9 to rotate through its connection with the fixed block 9. There is a threaded connection relationship between the fixed block 9 and the threaded rod 10. When the fixed block 9 rotates, the threaded rod 10 will move inside the rotating column 2. As the threaded rod 10 moves, the tool 11 will also move accordingly, thereby achieving the purpose of adjusting the length of the tool 11.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The protection component includes a baffle 12, the outer wall of the baffle 12 is slidably connected to the outer wall of the fixing frame 1, the inner thread of the fixing frame 1 is connected with a screw 14, one end of the screw 14 is fixedly connected with a handle 2 13, and the other end of the screw 14 is fixedly connected with a push block 16, the outer wall of the fixing frame 1 is fixedly connected with a positioning block 15, the outer wall of the push block 16 is slidably connected to the inner wall of the positioning block 15, the outer wall of the push block 16 is slidably connected with a card block 17, the outer wall of the card block 17 is slidably connected to the inside of the positioning block 15, the outer wall of the card block 17 is fixedly connected with a telescopic rod 18, and the outer wall of the telescopic rod 18 is sleeved with a spring 19, both ends of the spring 19 are fixedly connected to the outer wall of the card block 17, and the inside of the positioning block 15 is fixedly connected with a limit block 20, and the limit block 20 is fitted with the push block 16;

[0027] Specifically, first, the handle 2 13 is driven to realize the rotation control of the screw 14 through the connection with the screw 14. When the handle 2 13 is rotated, the screw 14 will rotate accordingly inside the fixed frame 1. Only by gently turning the handle can the movement control of the screw 14 be realized. Next, the rotation of the screw 14 will further drive the push block 16 to rotate inside the positioning block 15, so that the push block 16 can accurately control the position of the card block 17, thereby ensuring the installation accuracy of the baffle 12. When the push block 16 rotates, it will apply pressure to the card block 17 by moving, and push the card block 17 to the inside of the baffle 12. After the installation of the baffle 12 is completed, the staff can pull the card block 17 back to the inside of the positioning block 15 by rotating the handle 2 13 in the opposite direction with the force of the spring 19. This design makes the disassembly process of the baffle 12 equally simple. Only by gently turning the handle can the baffle 12 be taken out of the positioning block 15. Finally, the movement of the push block 16 is limited by the limit block 20 to prevent the spring 19 from causing damage.

[0028] Working principle: When the rotary tiller blade depth adjustment structure is needed, firstly, the rotating rod 3 is rotated to drive the toothed disc 4 to rotate inside the rotating column 2, so that the gear 6 drives the rotating shaft 5 to rotate inside the rotating column 2 along with the rotation of the toothed disc 4, and then drives the worm 7 to rotate, so that the worm wheel 8 rotates along with the rotation of the worm 7, thereby driving the fixed block 9 to rotate through the worm wheel 8. Due to the threaded connection relationship between the fixed block 9 and the threaded rod 10, the threaded rod 10 moves inside the rotating column 2, thereby driving the tool 11 to move. The effect of adjusting the length of the tool 11 is achieved, and then the handle 2 13 is driven to rotate, thereby driving the screw 14 to rotate inside the fixed frame 1, and then driving the push block 16 to rotate inside the positioning block 15, and then the block 17 is pressed by the movement of the push block 16, so that the block 17 is pushed to the inside of the baffle 12, and then the baffle 12 is installed, and then the handle 2 13 is rotated in the opposite direction, so that the spring 19 pulls the block 17 back to the inside of the positioning block 15, so that the baffle 12 is easily removed, thereby achieving the effect of disassembly and assembly.
