Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, and in particular to a rotary tiller mechanism for rotary tillers. Background Technology

[0002] Rotary tillers are agricultural machinery. They are widely used due to their strong soil-breaking ability and the ability to flatten the soil surface after tilling. They can also chop up stubble buried below the surface, facilitating seeder operations and providing a good seedbed for later sowing. Rotary tillers also break up the plow pan, restore soil structure, improve soil water retention, eliminate some weeds, reduce pests and diseases, level the surface, and improve the standards of agricultural mechanization.

[0003] The existing rotary tillage mechanism has a fixed tillage depth. Since the power transmission device needs to drive the blades to rotate through the power generated by the engine at the front end of the device, it is difficult to continue to use the power at the front end when changing the tillage depth. Adding some motors and other drive components makes it difficult to ensure stable tillage. Consequently, due to the need to ensure the drive input at the front end, it is difficult to change the tillage depth according to the needs of the work, which limits its use. Utility Model Content

[0004] This utility model discloses a rotary tillage mechanism for a rotary tiller, aiming to solve the problem that existing rotary tillage mechanisms have a fixed tilling depth. Because the power transmission device requires power generated by an engine at the front end of the device to drive the blades, it is difficult to continue using the front-end power when changing the tilling depth. Adding motors and other drive components makes it difficult to ensure stable tilling. Furthermore, because maintaining the drive input at the front end is crucial, it is difficult to change the tilling depth according to work needs, thus limiting its use. To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A rotary tiller mechanism includes a cover, inside which a drive rod is provided. Blades are uniformly fixedly connected to the rod wall of the drive rod. A housing is rotatably connected to the rod wall of the drive rod. A lifting assembly is provided at the upper end of the housing. A first bevel gear is fixedly connected to the rod wall of the drive rod. A rotating rod is rotatably connected to the upper right side of the housing. A second bevel gear is fixedly connected to the lower end of the rotating rod. The first bevel gear and the second bevel gear are meshed together. A rectangular rod is fixedly connected to the upper end of the rotating rod. A circular block is rotatably connected to the upper end of the cover. The interior of the circular block is slidably connected to the exterior of the rectangular rod. A third bevel gear is rotatably connected to the exterior of the circular block. A power rod is rotatably connected to the upper end of the cover. A fourth bevel gear is fixedly connected to the front end of the power rod. The fourth bevel gear and the third bevel gear are meshed together.

[0006] Preferably, a dust cover is fixedly connected to the upper end of the cover;

[0007] Preferably, the upper end of the dust cover is rotatably connected to a rotating block, and the interior of the rotating block is slidably connected to the upper end of the rectangular rod;

[0008] Preferably, the lifting assembly includes a motor fixedly connected to the upper end of the dust cover, a threaded rod fixedly connected to the output end of the motor, a rod member threadedly connected to the wall of the threaded rod, and the lower end of the rod member fixedly connected to the upper end of the housing.

[0009] Preferably, both sides of the cover are provided with sliding grooves, and a slider is slidably connected inside the sliding groove. The slider is rotatably connected to one side of the drive rod.

[0010] As can be seen from the above, the advantages of the rotary tillage mechanism for a rotary tiller provided by this utility model are as follows: During operation, the drive rod moves up and down through the lifting assembly according to the required tillage depth. At the same time, when the drive rod moves, under the action of the rectangular rod and the circular block, the drive rod can be rotated through the power rod regardless of its position, ensuring good driving force and improving the applicability of the device.

[0019] Reference Figure 1-4A rotary tiller mechanism includes a cover 1, which prevents soil from flying around and also functions as a device component. Inside the cover 1 is a drive rod 8. Rotation of the drive rod 8 drives the blades 18 to rotate, achieving soil turning. Blades 18 are evenly and fixedly connected to the wall of the drive rod 8. A housing 7 is rotatably connected to the wall of the drive rod 8. A lifting assembly is located at the upper end of the housing 7, which can move the drive rod 8 up and down, thereby changing the depth of soil turning. A first bevel gear 9 is fixedly connected to the wall of the drive rod 8. A rotating rod 10 is rotatably connected to the upper right side of the housing 7. A second bevel gear 11 is fixedly connected to the lower end of the rotating rod 10. The first bevel gear 9 and the second bevel gear 11 mesh with each other, and the second bevel gear 11 can drive... The first bevel gear 9 rotates, which in turn causes the drive rod 8 to rotate. A rectangular rod 14 is fixedly connected to the upper end of the rotating rod 10. A circular block 12 is rotatably connected to the upper end of the cover 1. The inside of the circular block 12 is slidably connected to the outside of the rectangular rod 14. The rectangular rod 14 can move up and down relative to the circular block 12. At the same time, when the circular block 12 rotates, it can drive the rectangular rod 14 to rotate. A third bevel gear 13 is rotatably connected to the outside of the circular block 12. A power rod 4 is rotatably connected to the upper end of the cover 1. A fourth bevel gear 15 is fixedly connected to the front end of the power rod 4. The rotation of the power rod 4 causes the fourth bevel gear 15 to rotate. The rotation of the fourth bevel gear 15 can drive the third bevel gear 13 to rotate, which in turn causes the circular block 12 to rotate. The fourth bevel gear 15 and the third bevel gear 13 are meshed together.

[0020] During operation, the height of the drive rod 8 is adjusted via the lifting assembly according to work requirements. After adjustment, the power rod 4 rotates, driving the fourth bevel gear 15 to rotate. The fourth bevel gear 15 drives the third bevel gear 13 to rotate. The third bevel gear 13 rotates, driving the circular block 12 to rotate. The circular block 12 rotates, driving the rectangular rod 14 to rotate. The rectangular rod 14 drives the rotating rod 10 to rotate. The rotating rod 10 rotates, driving the second bevel gear 11 to rotate. The second bevel gear 11 drives the first bevel gear 9 to rotate. When the lifting assembly moves the drive rod 8 up and down, the rectangular rod 14 moves up and down relative to the circular block 12. While the circular block 12 rotates, it can still drive the rotating rod 10 to rotate. Thus, during operation, the drive rod 8 is moved up and down via the lifting assembly according to the required soil turning depth. At the same time, when the drive rod 8 moves, under the action of the rectangular rod 14 and the circular block 12, regardless of the position of the drive rod 8, it can be driven to rotate by the power rod 4, ensuring good driving force and improving the applicability of the device.

[0021] Reference Figure 2-4 A dust cover 2 is fixedly connected to the upper end of the cover 1. The dust cover 2 can prevent external dust from affecting the meshing of the fourth bevel gear 15 and the third bevel gear 13.

[0022] Reference Figure 2-4The upper end of the dust cover 2 is rotatably connected to a rotating block 16. The interior of the rotating block 16 is slidably connected to the upper end of the rectangular rod 14. The rotating block 16 improves the sealing effect of the dust cover 2.

[0023] Reference Figure 3 The lifting assembly includes a motor 3 fixedly connected to the upper end of the dust cover 2. A threaded rod 19 is fixedly connected to the output end of the motor 3. A rod 17 is threadedly connected to the wall of the threaded rod 19. The lower end of the rod 17 is fixedly connected to the upper end of the housing 7. When the motor 3 starts, it drives the threaded rod 19 to rotate. The rotation of the threaded rod 19 causes the rod 17 to move up and down. The movement of the rod 17 causes the housing 7 to move up and down, which in turn drives the drive rod 8 to move.

[0024] Reference Figure 2 Both sides of the cover 1 are provided with sliding grooves 5, and a slider 6 is slidably connected inside the sliding groove 5. The slider 6 is rotatably connected to one side of the drive rod 8. By setting the slider 6, when adjusting the movement of the drive rod 8, the slider 6 moves up and down inside the sliding groove 5, thereby improving the stability of the drive rod 8.

[0025] Working Principle: During operation, the height of the drive rod 8 is adjusted via the lifting assembly according to the work requirements. After adjustment, the power rod 4 rotates, driving the fourth bevel gear 15 to rotate. The fourth bevel gear 15 drives the third bevel gear 13 to rotate, which in turn drives the circular block 12 to rotate. The circular block 12 then drives the rectangular rod 14 to rotate, which in turn drives the rotating rod 10 to rotate. The rotating rod 10 then drives the second bevel gear 11 to rotate, which in turn drives the first bevel gear 9 to rotate. When the lifting assembly moves the drive rod 8 up and down, the rectangular rod 14 moves up and down relative to the circular block 12. While the circular block 12 is rotating, it can still drive the rotating rod 10 to rotate. Thus, during operation, the drive rod 8 is moved up and down via the lifting assembly according to the required soil turning depth. Simultaneously, when the drive rod 8 moves, under the action of the rectangular rod 14 and the circular block 12, regardless of the position of the drive rod 8, it can be driven to rotate by the power rod 4, ensuring good driving force and improving the applicability of the device.
