[0033] Working principle: When the height of the belt conveyor body 102 needs to be adjusted, the staff can rotate the threaded rod 110 to make the threaded rod 110 move along the first vertical plate 104. When the threaded rod 110 moves, it will drive the tooth plate 111 to move together. When the tooth plate 111 moves, the length of the telescopic rod 112 will be extended. At the same time, the staff starts the motor 106 to rotate the gear 109. After the motor 106 is started, the belt conveyor body 102 will also start and transport the goods. When the tooth plate 111 moves, it will contact and mesh with the gear 109, so that the gear 109 moves along the tooth plate 111. When the gear 109 moves, it will drive the motor 106 and the horizontal plate 107 to move together. 07 will slide along the first slide groove 108 when it moves.

Before the first vertical plate 104 and the second vertical plate 116 collide, the rubber pad 24 will first contact the second vertical plate 116. Because the rubber pad 24 is made of flexible material, the rubber pad 24 will reduce the impact of the slide bar 23 and the second vertical plate 116 when they collide. When the slide bar 23 and the second vertical plate 116 contact, they will slide along the sleeve 2 under the action of pressure. The slide bar 23 will transmit the pressure to the damping spring 22, so that the damping spring 22 is in a compressed state. When the damping spring 22 is compressed, The impact generated when the slide bar 23 collides with the second vertical plate 116 is absorbed, and then the damping spring 22 transmits the attenuated impact to the sleeve 2 and the first vertical plate 104, thereby reducing the damage caused by the collision between the first vertical plate 104 and the second vertical plate 116; when the rubber pad 24 collides with the second vertical plate 116, the rubber pad 24 slides along the sleeve 2, and the movement of the rubber pad 24 drives the fixed plate 3 to move together, and the fixed plate 3 moves to contact the airbag 32 and squeeze the airbag 32.

When the sleeve 2 moves, it will drive the elastic rod 4 and the telescopic plate 42 to move together. When the telescopic plate 42 moves, it will contact the inner wall of the second slide groove 115. The telescopic plate 42 will transmit pressure to the elastic rod 4 so that the elastic rod 4 is in a bent state. When the elastic rod 4 is bent, the telescopic plate 42 will be close to the inner wall of the second slide groove 115 and clean the inner wall of the second slide groove 115, reduce impurities attached to the inner wall of the second slide groove 115, improve the cleanliness and smoothness of the inner wall of the second slide groove 115, and reduce the jamming of the first vertical plate 104 when sliding; the surface of the elastic net 5 is coated with adhesive. When the telescopic plate 42 cleans the inner wall of the second slide groove 115, dust will be diffused. The diffused dust When in contact with the elastic net 5, it will be adsorbed by the elastic net 5, reducing the impurities diffused when the telescopic plate 42 cleans the inner wall of the second chute 115; when the horizontal plate 107 slides along the first chute 108, it will contact and squeeze the rotating wheel 62, and the rotating wheel 62 will rotate under the friction and pick up the lubricating oil in the oil bag 6. When the rotating wheel 62 contacts the horizontal plate 107, the middle part of the horizontal plate 107 will be coated with lubricating oil, improving the smoothness of the surface of the horizontal plate 107 and reducing the jamming of the horizontal plate 107 when sliding along the first chute 108; when the rotating wheel 62 coats the horizontal plate 107 with lubricating oil, there will be dripping lubricating oil, which will reach the inside of the collecting box 7 and be collected by the collecting box 7, thereby improving the utilization rate of the lubricating oil by the device. ;
