The cotton opening assembly is located at the inner side of the feed end of the U-shaped cavity 101 to grab the raw cotton from the storage hopper 2 and spread the raw cotton. The cotton opening assembly includes a cotton feed roller 4, a cotton opening roller 5, a linkage assembly and a first motor 7. The cotton opening roller 5 is located below the gap between the two cotton feed rollers 4, and the cotton feed roller 4 and the cotton opening roller 5 are both rotatably connected to the chassis 1, and the cotton feed roller 4 and the cotton opening roller 5 are transmission-connected through the linkage assembly. The first motor 7 is arranged on the chassis 1 and synchronously drives the cotton feed roller 4 and the cotton opening roller 5 to rotate. The linkage assembly includes a gear 401, a first pulley 402, a second pulley 501 and a toothed belt 6. The two gears 401 are respectively connected to the rotating shafts of the two cotton feed rollers 4, and the two gears 401 are meshed and connected. The first pulley 402 is connected to the rotating shaft of one of the cotton feed rollers 4, the second pulley 501 is connected to the rotating shaft of the cotton opening roller 5, and the first pulley 402 and the second pulley 501 are connected by a toothed belt 6 transmission. The screen 10 is located at the horizontal end of the U-shaped cavity 101 and is connected to the inner wall of the chassis 1, and an elastic section is arranged in the middle of the screen 10. The vibration assembly 11 is connected to the chassis 1. When the vibration assembly 11 is in the working state, the elastic section of the screen 10 bumps up and down to accelerate the separation of cotton and impurities. The vibration assembly 11 includes a mounting shaft, a cam and a second motor. The mounting shaft is rotatably connected to the chassis 1, the cam is connected to the mounting shaft, and the second motor is arranged on the chassis 1, and its output end is connected to the end of the mounting shaft. The blower 12 is connected to the outside and the U-shaped cavity 101 to blow the cotton that has fallen on the screen 10 and has been separated out along the discharge port of the U-shaped cavity 101. The discharge pipe 13 is connected to the horizontal end of the U-shaped cavity 101 and is located below the screen 10. The guide roller 14 is located in the discharge pipe 13 and is slidably connected to its inner wall. A plurality of receiving grooves 141 are arranged in a circular array around its axis on the guide roller 14. A discharge channel 131 is arranged in the discharge pipe 13 and runs through it from top to bottom. A cylindrical cavity 132 is arranged in the discharge pipe 13. The cylindrical cavity 132 is located between the inlet and outlet of the discharge channel 131 and is connected to the discharge channel 131. The guide roller 14 is located in the cylindrical cavity 132 and is slidably connected to its inner wall. And a driving component, the driving component drives the connected guide roller 14 to rotate in the discharge pipe 13, so that each receiving groove 141 circulates to discharge impurities and maintains the sealing between the discharge pipe 13 and the guide roller 14.
