[0031] In specific use, when conveying, the technical personnel in this field place the wood inside the placement box 620, start the first motor 410, make the conveyor belt body 400 run, and make the push block 690 move. When the push block 690 contacts the force-bearing plate 680, it drives the force-bearing plate 680 to move, so that the connecting box 660 drives the sealing plate 640 to move, and the discharge port 642 moves to the inside of the discharge pipe 630.

When the first motor 410 is started, the driving wheel 591 is rotated, and the connecting belt is used to 592, drives the driven wheel 590 to rotate, so that the rotating rod 550 rotates, drives the connecting plate 560 to rotate, and causes the squeezing column 561 to deflect.

When the squeezing column 561 separates from the vertical rod 531, another squeezing column 561 deflects to the bottom of the L-shaped rod 580, squeezes the L-shaped rod 580, and causes the L-shaped rod 580 to deflect upward, so that the notch 581 squeezes the connecting rod 532, causes the installation rod 530 to move left, and drives the vertical rod 531 to move left. Then The extrusion column 561 deflected upward squeezes the vertical rod 531 again, so that the mounting rod 530 moves back and forth, driving the sliding plate 520 to move back and forth, and then driving the cleaning brush 521 to move back and forth, so as to clean the conveyor belt body 400 and avoid wood chips from remaining. When the conveying direction needs to be changed, the first motor 410 is turned off and the second motor 760 is started. The rotation of the second motor 760 drives the worm 750 to rotate, so that the worm wheel 740 rotates, thereby driving the rotating shaft 720 to rotate, so that the turntable 730 rotates, and drives the shell 300 to rotate, thereby changing the conveying direction of the conveyor belt body 400, and starting the first motor 410 again for conveying.
