Through the meshing relationship between gear 4, the accuracy and stability of the relative motion of two crushing rollers 3 are ensured. The outer wall of one of gear 4 is fixedly connected with first pulley 6. One side of first pulley 6 is fixedly connected with second pulley 24, and the other side of first pulley 6 is fixedly connected with transmission assembly, and the right outer wall of machine body 1 is rotationally connected with first pulley 6 in the middle, and the first pulley 6 in the middle of the right outer wall of machine body 1 plays a pivotal role in the whole power transmission chain. It transmits power to second pulley 24 through the belt connection, and then drives the screening assembly to work, realizes the screening separation of crushed straw, on the other hand, the power is transmitted to the transmission assembly, provides power for the compression assembly, so that the crushing and compression process can be orderly connected, the screening assembly is installed in the bottom of machine body 1, the main function of the screening assembly is to screen the crushed straw, separate the straw meeting the size requirement from the larger particles or the straw and soil not fully crushed, the collecting box 15 is arranged on the front side of machine body 1, the compression assembly is arranged in the collecting box 15, and the collecting box 15 is used for collecting the qualified straw after screening, provides the working space and material storage place for the compression assembly. The compression assembly is arranged in the collecting box 15, so that the crushing, screening and compression process can be completed in a relatively compact space, the material transfer distance and time are reduced, and the overall working efficiency of the device is improved.

[0033] Referring to Figure 3, the screening assembly includes a rotating shaft 18 and a screen 20, the rotating shaft 18 is rotatably connected to the inner wall of the machine body 1, the rotating shaft 18 is the core rotating part of the screening assembly, and is rotatably connected to the inner wall of the machine body 1, thereby providing a basis for the installation of the eccentric wheel 19 and the second pulley 24. Through the connection with the second pulley 24, the power from the first pulley 6 is received to realize rotation. The screen 20 is installed inside the machine body 1, and the screen 20 is a key part for realizing the screening of the straw. The screen 20 is installed inside the machine body 1, and the screen hole size is designed according to the predetermined size requirement of the straw.

[0038] With reference to Figure 3 The outer walls of the left and right sides of the screen 20 are fixedly connected with sliding blocks 21, and the inner walls of the left and right sides of the screen 20 are provided with sliding grooves 22. When the eccentric wheel 19 drives the screen 20 to vibrate, the sliding blocks 21 slide in the sliding grooves 22, so that the screen 20 can only vibrate in the predetermined direction, preventing the screen 20 from deviating or shaking, improving the working stability and reliability of the screen 20, and facilitating the installation, disassembly and maintenance of the screen 20.

[0039] With reference to Figure 1The outer wall on the right side of the machine body 1 is fixedly connected with two mounting plates 16, the two mounting plates 16 are fixedly connected with a sliding rod 17, and the connecting rod 12 is slidably connected to the outer wall of the sliding rod 17. When the transmission assembly is working, the connecting rod 12 slides on the sliding rod 17, so that the connecting rod 12 can only reciprocate in the vertical direction, avoiding horizontal deviation or shaking during movement, so that the compression assembly can stably compress the straw in the collecting box 15, improving the accuracy and reliability of the compression process.

[0040] Referring to Figure 3 The top of the pressing rod 13 is fixedly connected to one end of the connecting rod 12 away from the fixed rod 11, so that the connecting rod 12 can directly transmit the power generated by the transmission assembly to the pressing rod 13, thereby driving the pressing plate 14 to compress the straw.

[0041] Working principle: when the rice straw is crushed, the rice straw is conveyed into the inlet 2 by using the auger, then the motor 5 is energized, so that the motor 5 rotates, one of the motors 5 rotates, and the other gear 4 rotates through the gear 4, the straw is crushed, the gear 4 also drives the first pulley 6 to rotate, and another first pulley 6 is driven to rotate through the belt, so that the second pulley 24 and the rotating disc 7 rotate, the second pulley 24 drives another second pulley 24 to rotate through the belt, so that the rotating shaft 18 rotates and drives the eccentric wheel 19 to rotate, the screen 20 is hit, so that the screen 20 slides up and down, the crushed straw is separated from the soil, then falls into the collecting box 15 for collection. When the rotating disc 7 rotates, the eccentric shaft 8 rotates and drives the rotating frame 10 to slide up and down, further drives the fixed rod 11 and the connecting rod 12 to slide up and down, so that the pressing rod 13 slides up and down, further drives the pressing plate 14 to slide up and down to extrude and shape the crushed straw in the collecting box 15.
