The first bevel gear 13 and the third bevel gear 16 mesh and drive each other, thereby causing the rotating shaft 15 to rotate. At the same time, the rotating shaft 15 drives the first driving wheel 151 to rotate. Then, the first synchronous belt 19 drives the first driven wheel 171 to rotate, thereby causing the fixed rod 17 to drive the cutter 18 to crush the straw. When the straw is crushed... When the motor 4 is turned on, the threaded rod 41 rotates, causing the threaded plate 42 and connecting plate 43 to be pulled out, thus creating a gap between the drum 24 and the housing 1 to allow the chopped straw to be scattered. Then, when it is necessary to clean the chopped straw adhering to the inside of the housing 1 and the surface of the drum 24, the motor 4 is turned on, causing the threaded rod 41 to rotate, causing the threaded plate 42 to drive the connecting plate 43 to slide, and the connecting plate 43 to drive the brush 44 to clean the inside of the housing 1 and the surface of the drum 24, thereby avoiding blockage caused by the chopped straw. This eliminates the need for manual cleaning by workers and improves the overall chopping efficiency.
[0024] A sleeve 23 is rotatably provided inside the housing 1. A roller 24 is fixedly fitted on the outer surface of the sleeve 23. An extension plate 25 is fixedly fitted on the outer surface of the roller 24. A protective shell 3 is fixedly provided on one side of the housing 1. A blower 31 is fixedly provided inside the protective shell 3. A conveying pipe 32 is fixedly provided on the bottom surface of the blower 31.

[0025] By adopting the above technical solution, by turning on the blower 31, air can be sent into the conveying pipe 32 and then blown out from the air outlet pipe 33. At the same time, the sleeve 23 and the roller 24 rotate. When the air outlet pipe 33 is connected to the first through groove 231 and the second through groove 241, air can be blown out from the first through groove 231 and the second through groove 241 and blown out the chopped straw on the extension plate 25, so that it can be evenly spread in the field and fully mixed with the soil.
[0026] A rotating rod 2 is rotatably provided inside the transmission box 11. A fourth bevel gear 21 is fixedly provided at one end of the rotating rod 2. A second bevel gear 14 meshes with the fourth bevel gear 21. A second driving wheel 22 is fixedly sleeved on the outer surface of the rotating rod 2. A second driven wheel 26 is fixedly sleeved on the outer surface of the sleeve 23. A second synchronous belt 27 is connected between the second driving wheel 22 and the second driven wheel 26.
[0027] By adopting the above technical solution, the transmission rod 12 is connected to the power output shaft of the tractor through a universal joint. The power output shaft and the universal joint transmit power to the transmission rod 12, thereby causing the first bevel gear 13 and the second bevel gear 14 to rotate. The second bevel gear 14 then drives the fourth bevel gear 21 to mesh and transmit power, causing the rotating rod 2 to drive the second driving wheel 22 to rotate. This causes the second synchronous belt 27 to drive the second driven wheel 26 to rotate, and then the sleeve 23 drives the drum 24 to rotate. This causes the extension plate 25 to throw out the chopped straw, which facilitates the discharge of the chopped straw.
[0028] Working principle: First, the tractor's suspension mechanism is connected via a hanging rod on top of the housing 1. Then, the transmission rod 12 is connected to the tractor's power take-off shaft via a universal joint. When straw needs to be chopped, the motor 4 is turned on, causing the threaded rod 41 to rotate and pull out the threaded plate 42 and connecting plate 43, thus creating a gap between the roller 24 and the housing 1 to allow the chopped straw to be scattered. The power is transmitted to the transmission rod 12 via the power take-off shaft and universal joint, which in turn causes the first bevel gear 13 and the second bevel gear 14 to rotate. Then, the first bevel gear 13 and the third bevel gear 16 mesh to transmit power. The movement causes the rotating shaft 15 to rotate, which in turn drives the first driving wheel 151 to rotate. Then, the first synchronous belt 19 drives the first driven wheel 171 to rotate, which in turn drives the fixed rod 17 to drive the cutter 18 to crush the straw. At the same time, the second bevel gear 14 drives the fourth bevel gear 21 to mesh and drive the rotating rod 2 to drive the second driving wheel 22 to rotate, which in turn drives the second synchronous belt 27 to drive the second driven wheel 26 to rotate. Then, the sleeve 23 drives the roller 24 to rotate, which in turn causes the extension plate 25 to throw out the chopped straw, thus facilitating the discharge of the chopped straw.
[0029] Then, the blower 31 is turned on, which sends air into the conveying pipe 32 and blows it out from the air outlet pipe 33. At the same time, the sleeve 23 and the roller 24 rotate. When the air outlet pipe 33 is connected to the first through groove 231 and the second through groove 241, the air can be blown out from the first through groove 231 and the second through groove 241 and blown out the chopped straw on the extension plate 25, so that it can be evenly spread in the field and fully mixed with the soil. Then, when it is necessary to clean the chopped straw adhering to the inside of the shell 1 and the surface of the roller 24, the motor 4 is turned on, which causes the threaded rod 41 to rotate, causing the threaded plate 42 to drive the connecting plate 43 to slide, and the connecting plate 43 to drive the brush 44 to clean the inside of the shell 1 and the surface of the roller 24, thereby avoiding the clogging caused by the chopped straw. Manual cleaning by workers is not required, which improves the overall chopping efficiency.
