[0021] The device is installed on the rear side of the tractor, and there are three connection points on the connecting frame 2. The three connection points are connected to the three suspensions on the rear side of the tractor. The shell 1 is located on the rear side of the connecting frame 2, and the connecting frame 2 is located in the middle of the shell 1. The width of the shell 1 is the same as the width of the field ridges where crops are planted. The connecting frame 2 and the shell 1 move with the tractor, and the front side of the shell 1 is open. The cutting table 3 is located at the frontmost position of the shell 1. The cutting table 3 is composed of two rows of horizontally sliding cutters. When the cutting table 3 is pulled by the shell 1, the cutting table 3 will cut off the connection between the crops and the surface of the ground. The cut crops enter the shell 1 under the action of the shell 1. The crops pass through the conveyor belt 4, the crushing roller 5 and the granulating component in the shell 1 in turn, wherein the conveyor belt 4 is tilted, and the conveyor belt 4 transports the stems of the crops to a higher position, where the crushing roller 5 will radially crush the stems of the crops to achieve a ratio In a relatively broken state, after these rods are broken, they will fall downward under the action of the crushing roller 5 and gravity, and the broken rods will eventually fall into the granulation component, and the granulation component will squeeze these fluffy and broken rods, so that the crop rods will eventually become a relatively compact long strip structure, and these long strip structure wastes will eventually be discharged from the discharge port 6, so that the relatively fluffy crop waste will eventually be retained in the sky with a smaller particle volume; the granulation component is provided with a first squeezing roller 7 and a second squeezing roller 8, and the first squeezing roller 7 and the second squeezing roller 8 are both provided with a pressing groove. The first squeezing roller 7 and the second squeezing roller 8 are synchronously squeezed to compact the crop waste, and the first gear 9 on the first squeezing roller 7 and the second gear 10 on the second squeezing roller 8 have the same module, and the first gear 9 and the second gear 10 are meshed with each other, so that the first squeezing roller 7 and the second squeezing roller 8 keep synchronous reverse rotation during movement.

[0022] The conveyor belt 4, crushing roller 5 and first squeezing roller 7 on the shell 1 rotate synchronously, the motor on the driving assembly is connected to the first pulley 12, the first pulley 12, the second pulley 13 and the third pulley 14 drive the three to rotate synchronously through the connecting belt 15, the first pulley 12 is fixedly connected to the driving roller at the upper end of the conveyor belt 4, the first pulley 12 drives the conveyor belt 4 to rotate, the second pulley 13 drives the crushing roller 5 to rotate, there are two crushing rollers 5, the two crushing rollers 5 rotate synchronously in opposite directions under the action of two third gears 11, the two crushing rollers 5 can improve the crushing efficiency of the crop stems, the rotation of the third belt drives the first squeezing roller 7 to rotate, so that one motor drives the various components in the shell 1 to move synchronously, reducing the number of motors installed in the device.

[0023] The conveyor belt 4 is provided with a filtering hole 16. The shell 1 at the bottom of the conveyor belt 4 is a bottomless structure. The filtering holes 16 on the conveyor belt 4 can filter out some soil blocks to prevent the soil blocks from entering the position of the crushing roller 5, thereby reducing the dust problem when the device is working; the drop hopper 17 is located below the crushing roller 5. The drop hopper 17 is a V-shaped structure. The drop hopper 17 can make the crushed crop waste better gather above the first squeezing roller 7 and the second squeezing roller 8, so that the first squeezing roller 7 and the second squeezing roller 8 can squeeze the crop waste into particles.

[0024] There are four rollers, which are located at the four corners of the shell 1. The heights of the four rollers can be adjusted by a handle 20. The lower end of the handle 20 is threadedly connected to the support rod 18. The support rod 18 and the fixed block 19 can only slide vertically. The fixed block 19 is fixed on the shell 1. The handle 20 is rotatably connected to the fixed block 19. When the handle 20 rotates, the vertical height of the handle 20 relative to the fixed block 19 remains unchanged. The threaded connection between the handle 20 and the support rod 18 causes the support rod 18 to move downward. Example 2

[0025] The structure is the same as the above embodiment. Figure 5 As shown, the specific difference of this embodiment is that a partition plate 21 is fixedly connected to the discharge port 6, a plowshare 22 is provided on the front side of the discharge port 6, and the plowshare 22 is fixedly connected to the shell 1.
