It includes: a cotton stalk pulling and planing mechanism 4. The cotton stalk pulling and planing mechanism 4 includes a suspension frame 5, a bracket 7, a lifting assembly, a transmission assembly, a rotary knife assembly and a straw pushing part. The suspension frame 5 is detachably connected to the frame. The transmission assembly is in transmission connection with the universal joint assembly 3. The lifting assembly is fixedly connected to the top surface of the bracket 7. The lifting assembly is installed on the suspension frame 5. The suspension frame 5 is slidably connected to the bracket 7. A rotary knife assembly is installed on the bottom surface of the bracket 7. A straw pushing part is installed on one side of the bracket 7 away from the suspension frame 5. The straw pushing part and the rotary knife assembly are in transmission connection through the transmission assembly.

[0030] During operation, the power machine 1 transmits power to the cotton stalk pulling and planing mechanism 4 through the separation box 2 and the universal joint assembly 3. The lifting assembly drives the bracket 7 to move vertically, thereby adjusting the height of the stalk pulling part to align it with the main lateral roots 35 of the cotton stalk. The power is transmitted to the stalk pulling part through the transmission assembly, pulling the cotton stalk plants out of the soil. The high-speed rotation of the rotary knife assembly can further plane the remaining main lateral roots 35 of the cotton stalk in the soil. The present invention does not require soil penetration during the stalk pulling operation, consumes less power, and the rotary knife assembly rotates evenly, capable of secondarily eliminating the remaining main lateral roots of the cotton stalk in the soil.

[0031] In a further optimized solution, the stalk pulling part includes a first stalk pulling assembly 23 and a second stalk pulling assembly 28.

The transmission assembly transmits power to the first stalk pulling transmission box 22, and the first stalk pulling transmission box 22 transmits power to the second stalk pulling transmission box 27 through the connecting sleeve 26. The first stalk pulling transmission box 22 and the second stalk pulling transmission box 27 drive the longitudinal stalk pulling rollers 31 and the pushing rod wheel assemblies 8 to rotate, thereby pulling up the cotton stalks. The longitudinal stalk pulling rollers 31 can complete the stalk pulling work without entering the soil, reducing energy consumption.

[0033] In a further optimized solution, the longitudinal stalk pulling roller 31 includes a short stalk pulling roller and a long stalk pulling roller. Pulling ribs 30 are respectively fixedly connected to the circumferential outer surfaces of the short stalk pulling roller and the long stalk pulling roller.

The structure of the second rotary knife assembly 15 is the same as that of the first rotary knife assembly 14. The transmission assembly transmits power to the second sprocket 13 and the third sprocket 16. The second sprocket 13 drives the moving knife shaft 34 on the first rotary knife assembly 14 to rotate, and the third sprocket 16 drives the moving knife shaft 34 on the second rotary knife assembly 15 to rotate, and then drives the moving knife brackets 32 and the spiral edge moving knives 33 to rotate, so as to clean the lateral roots of the residual cotton stalks.

[0037] For a further optimized solution, the transmission assembly includes a main transmission case 21 fixedly connected to the top surface of the bracket 7.

A fifth sprocket 20 is fixedly connected to the end of the first output shaft 10 away from the main transmission case 21. A sixth sprocket 25 is fixedly connected to the connecting sleeve 26. The fifth sprocket 20 is drivingly connected to the sixth sprocket 25 through a chain. A fourth sprocket 17 is drivingly connected to one side of the second lever transmission case 27 away from the connecting sleeve 26. The fourth sprocket 17 is drivingly connected to a third sprocket 16 through a chain. The power machine 1 transmits the power to the main transmission case 21 through the separation box 2 and the universal joint assembly 3. The power of the main transmission case 21 is transmitted to the second sprocket 13 through the second output shaft 11 and the first sprocket 12 by chain drive, thereby driving the first rotary knife assembly 14 to rotate. The power of the main transmission case 21 is transmitted to the sixth sprocket 25 through the first output shaft 10 and the fifth sprocket 20 by chain drive, and then the power is transmitted to the first lever transmission box 22. In addition, the sixth sprocket 25 drives the connecting sleeve 26 to rotate, and the connecting sleeve 26 transmits the power to the second lever transmission box 27. The first lever transmission box 22 drives the first lever assembly 23 to rotate through the longitudinal lever roller 31.

The first lever assembly 23 and the second lever assembly 28 respectively drive the two transmission members 24 to rotate, and the transmission members 24 drive the lever wheel 29 to rotate. In addition, the second lever transmission box 27 simultaneously drives the fourth sprocket 17 to rotate, and then transmits the power to the third sprocket 16 through chain drive, thereby driving the second rotary knife assembly 15 to rotate.

The side slide rails are slidably connected to the lifting frame 19 and limit the lifting frame 19 through limit holes to prevent deviation. The lifting frame 19 includes an upper cross beam, sliding longitudinal beams, support channel steels and connecting pipes. The sliding longitudinal beams are adapted to the side slide rails to improve the sliding performance. When it is necessary to adjust the height of the bracket 7, only need to control the lifting oil cylinder 18 to extend and retract, and the operation is simple and convenient.

[0039] For a further optimized solution, a suspension hook 6 is fixedly connected to the side wall of the suspension bracket 5. The suspension hook 6 is detachably connected to the frame. The suspension hook 6 on the suspension bracket 5 is hung on the front forehead suspension channel steel of the frame and fastened by bolts, which is convenient for installation and disassembly.

[0040] Working process of the present invention: During the stalk pulling operation, the power machine travels to the cotton field, and the driver operates the lifting cylinder 18 to lower the cotton stalk pulling mechanism. Figure 6 , so that the front end of the inclined longitudinal stalk pulling roller 31 is located below the main root of the cotton stalk, Figure 7-8 , adjust the rotary knife assembly to the scraping position, operate the power machine, engage the separation box 2, and transmit the power to the cotton stalk pulling mechanism 4 through the universal joint assembly 3. When the power machine moves forward, the stalk pulling wheel 29 of the stalk pulling wheel assembly 8 pushes the cotton stalk into the longitudinal stalk pulling roller 31, and the longitudinal stalk pulling roller 31 clamps the cotton stalk and rolls in the opposite direction to generate an upward lifting force to pull the cotton stalk plants out of the soil. The first rotary knife assembly 14 and the second rotary knife assembly 15 rotate at a high speed to drive the obliquely installed spiral blade moving knife 33 to scrape the ground and rotate, and the main lateral roots 35 of the cotton stalk remaining in the soil are further removed.
