However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the present utility model can be realized even without these specific details.

[0023] Please refer to Figures 1 to 2 , the present utility model provides a sugarcane top cutting device with adjustable lifting, and the technical solution is as follows:

[0024] A sugarcane top cutting device with adjustable lifting, the sugarcane top cutting device includes a connecting rod assembly 1, a connecting rod driving assembly 2, a gear assembly 3 and a cutting assembly 4. The connecting rod assembly 1 includes a first connecting rod 11, a second connecting rod 12 and a third connecting rod 13. The first connecting rod 11 is rotatably connected to the second connecting rod 12. Specifically, one end of the first connecting rod 11 is rotatably connected to the second connecting rod 12 through a first connecting shaft 14. One end of the first connecting rod 11 is sleeved on the first connecting shaft 14 and is rotatably connected to the first connecting shaft 14. One end of the second connecting rod 12 is sleeved on the first connecting shaft 14 and is rotatably connected to the first connecting shaft 14. The second connecting rod 12 is rotatably connected to the third connecting rod 13. Specifically, the end of the second connecting rod 12 far from the first connecting rod 11 is rotatably connected to the third connecting rod 13 through a second connecting shaft 15. The end of the second connecting rod 12 far from the first connecting rod 11 is sleeved on the second connecting shaft 15 and is rotatably connected to the second connecting shaft 15. One end of the third connecting rod 13 is sleeved on the second connecting shaft 15 and is rotatably connected to the second connecting shaft 15.

[0025] The first connecting rod 11 is connected to the connecting rod driving assembly 2. Specifically, the connecting rod driving assembly 2 includes a driving shaft 21 and a driving motor 22. One end of the driving shaft 21 is fixedly connected to the end of the first connecting rod 11 away from the second connecting rod 12, and the other end of the driving shaft 21 is fixedly connected to the output end of the driving motor 22. The driving motor 22 is used to drive the driving shaft 21 to rotate. The driving shaft 21 drives the first connecting rod 11 to rotate. The end of the first connecting rod 11 away from the driving shaft 21 rotates around the driving shaft 21. While the second connecting rod 12 located at the end of the first connecting rod 11 away from the driving shaft 21 rotates following the first connecting rod 11, it moves upward, and the second connecting rod 12 drives the third connecting rod 13 to move upward.

[0026] A gear assembly 3 is provided on the second connecting rod 12. The gear assembly 3 includes a first gear 31 and a second gear 32. The first gear 31 is fixedly connected to the end of the first connecting shaft 14 away from the second connecting rod 12, and the second gear 32 is fixedly connected to the end of the second connecting shaft 15 away from the second connecting rod 12. The first gear 31 and the second gear 32 are meshed. By meshing the first gear 31 with the second gear 32 and connecting them to the second connecting rod 12 and the first connecting rod 11 through the connecting shafts, the first connecting rod 11, the second connecting rod 12, and the third connecting rod 13 move more smoothly during rotation and movement.

[0027] The third connecting rod 13 is rotatably connected to the cutting assembly 4 and is used to drive the cutting assembly 4 to move up and down. Specifically, the cutting assembly 4 includes a movable block 41, a rotating motor 42, and a cutter head 43. The movable block 41 is rotatably connected to the end of the third connecting rod 13 away from the second connecting rod 12. The movable block 41 is connected to a fixed seat 45 through a connecting block 44. A rotating motor 42 is fixedly provided at the upper end of the fixed seat 45. The output end of the rotating motor 42 extends downward through the fixed seat 45. A serrated cutter head 43 is provided at the lower end of the fixed seat 45, and the output end of the rotating motor 42 is fixedly connected to the cutter head 43. When the third connecting rod 13 moves up and down, it drives the movable block 41 to move up and down, thereby realizing the adjustment of the up and down movement of the cutter head 43.

[0028] In order to ensure the linearity and stability of the up-and-down movement of the cutter head 43, in this embodiment, a guiding assembly is further included. The guiding assembly includes two guiding rods 5 arranged in parallel at intervals. The upper ends of the two guiding rods 5 are fixedly arranged. In this embodiment, an L-shaped baffle 6 is arranged behind the guiding rod 5, and the upper end of the guiding rod 5 is fixedly connected to the upper end of the baffle 6. The lower end of the guiding rod 5 extends downward. A fixing block 7 is arranged on the guiding rod 5. One end of the fixing block 7 is sleeved on one of the guiding rods 5 and fixedly connected to this guiding rod 5. The other end of the fixing block 7 is sleeved on the other guiding rod 5 and fixedly connected to the other guiding rod 5. The driving motor 22 is fixedly arranged at the rear side of the baffle 6. One end of the driving shaft 21 far away from the driving motor 22 passes through the baffle 6 and the fixing block 7 and is fixedly connected to the first connecting rod 11. The driving shaft 21 is rotatably connected to the baffle 6 and the fixing block 7 respectively. The movable block 41 is arranged below the fixing block 7. One end of the movable block 41 is sleeved on one of the guiding rods 5 and is slidably connected to this guiding rod 5. The other end of the movable block 41 is sleeved on the other guiding rod 5 and is slidably connected to the other guiding rod 5. In order to reduce the sliding friction between the movable block 41 and the guiding rod 5, a sliding cylinder is arranged between the movable block 41 and the guiding rod 5. The sliding cylinder is fixedly arranged on the movable block 41, sleeved on the guiding rod 5, and slidably connected to the guiding rod 5.

[0029] The guiding rod 5 plays a limiting role on the movable block 41, which can prevent the movable block 41 from driving the cutter head 43 to swing left and right and affect the cutting effect. When the third connecting rod 13 moves upward, it drives the movable block 41 to move upward. Due to the limitation of the movable block by the guiding rod 5, it will move vertically upward along the guiding rod 5. The movable block 41 makes a linear movement, ensuring the stability of the movement of the cutter head 43.

[0030] Furthermore, a mounting plate member 8 is fixedly arranged at the rear side of the baffle 6, and a mounting hole 9 is provided on the mounting plate member 8. The mounting hole 9 is used to mount the device on the sugarcane harvester. Threads are provided on the mounting hole 9, and it is only necessary to insert and fix the screw rod.

[0031] During use, the device is mounted on the sugarcane harvester, and the device is moved to the three-dimensional coordinate points of each sugarcane for cutting. The driving motor 22 drives the first connecting rod 11 to rotate. When the first connecting rod 11 rotates, the second connecting rod 12 moves up and down while following the rotation of the first connecting rod 11. When the second connecting rod 12 moves, the third connecting rod 13 rotates around the connection point with the second connecting rod 12 and moves up and down. The third connecting rod 13 drives the movable block 41 to move up and down, thereby realizing the up-and-down movement of the cutter head 43.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
