A sliding block 14 is installed on the upper part of the reciprocating screw 16 for cooperation with it. A cleaning roller 12 is rotatably installed on one side of the sliding block 14. A gear 13 is fixedly installed on the side of the cleaning roller 12 away from the sliding block 14. The gear 13 meshes with the toothed plate 11. The outer surface of the cleaning roller 12 is in contact with the outer surface of one side of the dustproof plate 2. A fixing frame 17 is fixedly installed in the middle of one side of the pipe 1. A smoke exhaust fan 18 is installed on one side of the fixing frame 17.
[0021] The dustproof plate 2 has multiple grooves 21 on both sides. A spring 211 is fixedly installed in the middle of each groove 21. A limit bead 22 is fixedly installed on one side of each spring 211. One side of each limit bead 22 is slidably locked inside the groove 21.
