[0033] Working principle: During normal transportation, the lifting motor 205 is started, and the lifting motor 205 drives the lifting push screw 206 to rotate. When the lifting push screw 206 rotates, it pushes the threaded cylinder 211 to make the active slider 207 move to the right, thereby driving the driven slider 209 to move synchronously. When the driven slider 209 moves, the guide inclined hole 202 guides the toggle column 212, so that the driven slider 209 moves upward, so that the push wheel 213 pushes the lifting enclosure mechanism to rise, so that the enclosure corner 303 protrudes from the load-bearing frame 101 to form an enclosure, and then the goods are placed above the load-bearing frame 101 for transportation; When transporting goods of the same batch over a short distance, multiple devices are connected end to end at the starting point and the end point of the goods, and the lifting motor 205 is started. The lifting motor 205 drives the lifting and pushing screw 206 to rotate in the opposite direction. When the lifting and pushing screw 206 rotates, it pushes the threaded cylinder 211 to make the active slider 207 move to the left, thereby driving the driven slider 209 to move synchronously. When the driven slider 209 moves, the guide inclined hole 202 guides the toggle column 212, so that the driven slider 209 moves downward, so that the push wheel 213 pushes the lifting enclosure mechanism to descend, so that the enclosure angle 303 retracts the enclosure of the load-bearing frame 101, and then the electromagnet 410 of the rear device close to the front device is energized, and the electromagnet 410 attracts the armature ring 408, so that the positioning plug 407 is always extended from the positioning slide 406 inside the device, and inserted into the positioning slide 406 inside the front device, thereby forming a docking, to prevent the device from easily deviating to the side in the middle; Then, the conveying motor 111 and the dust removal fan 118 on the surface of all devices are started. After the conveying motor 111 is started, the conveying worm gear 115 is driven to rotate through the conveying worm 113. When the conveying worm gear 115 rotates, the conveying roller 105 is driven to rotate through the conveying shaft 104, thereby driving the conveyor belt 106 to move. At the same time, the conveying shaft 104 drives the driven bevel gear 112 through the active bevel gear 114 to feed back the rotation speed to the speed sensor 110, and then the rotation speed of the conveying motor 111 is adjusted to make the movement speed of each conveyor belt 106 consistent. When the dust removal fan 118 is started, the air intake of the side exhaust slot 117 is continuously pumped downward, so that the surface of the movable conveyor belt 106 is brushed by the cleaning brush 102 and then cleaned by blowing air, thereby ensuring the cleanliness of the surface of the conveyor belt 106; The goods are then placed on a conveyor belt 106 near the starting point, and the goods are continuously transported to the end point through the movement of the conveyor belt 106, thereby achieving transportation.
