The protrusion height of the rotating rollers 5 on the placing platform 3 is 0.5 cm, which can reduce the friction between the surfaces of the placing platform 2 between the goods during unloading, making it more convenient to unload the goods. A rear baffle 6 is fixedly installed on the right end of the upper surface of the vehicle body 1, which cooperates with the front baffle 4 to facilitate the limiting of the goods on the placing platform 3 and prevent the goods from falling from the placing platform 3.

[0022] Three adjustment grooves 8 are provided on the front and rear sides of the upper surface of the placement table 3. Screw rods 9 are rotatably installed inside the two middle adjustment grooves 8. A connecting plate 10 is screwed on the outer surface of the screw rod 9. A buffer frame 14 is fixedly installed on the top of the connecting plate 10. A group of guide rods 15 are interspersed on each buffer frame 14. Buffer baffles 16 are fixedly installed on the opposite ends of the two groups of guide rods 15 on different buffer frames 14. Adjustment frames 12 are fixedly installed on the front and rear sides of the vehicle body 1. Rotation grooves are provided on the opposite sides of the two adjustment frames 12. A rack 13 is fixedly installed on the inner wall of the rotating groove. One end of the screw rod 9 extends to the inside of the rotating groove, and a gear 11 is fixedly installed on one end of the screw rod 9, and the gear 11 is meshed with the rack 13.

[0023] When the goods are placed, the hydraulic rod 2 is started again to drive the placement table 3 to move downward. At the same time, when the placement table 3 moves downward, it will drive the gear 11 to rotate on the rack 13, drive the screw rod 9 to rotate, and drive the buffer frames 14 on both sides to move toward the center of the placement table 3, so as to drive the buffer baffle 16 to move and squeeze and fix the goods on the placement table 3, reduce the shaking of the goods when the device moves, reduce the collision damage between the goods, and improve the stability of the device during transportation. When transported to the destination, the hydraulic rod 2 is started to lift the placement table 3, which will drive the rack 11 to rotate, drive the two buffer baffles 16 to open and separate from the goods, and at the same time, the height of the placement table 3 is flush with the rear baffle 6, which is convenient for subsequent unloading of goods.

[0024] Furthermore, auxiliary support seats 7 are fixedly installed on both sides of the upper surface of the vehicle body 1 to assist in supporting the placement table 3 and improve the stability and load-bearing effect of the placement table 3 .

[0025] Among them, each group of guide rods 15 has two, and are arranged on the left and right sides of the buffer frame 14. The opposite ends of the guide rods 15 on different buffer frames 14 extend to the outside of the limiting slide plate 18, and are fixedly installed with the limiting plate. The outer surface of the guide rod 15 is sleeved with a spring 17, one end of the spring 17 abuts against the buffer baffle 16, and the other end of the spring 17 abuts against the buffer frame 14. When the buffer frame 14 drives the buffer baffle 16 to move and squeeze and fix the goods on the placement table 3, the elastic force of the spring 17 can be used to buffer the buffer baffle 16 to prevent the buffer baffle 16 from hard contact with the goods, which will damage the goods and affect the quality of the goods.

[0026] Furthermore, slide bars 19 are fixedly installed inside the adjustment grooves 8 on the left and right sides, and limiting slide plates 18 are fixedly installed on the bottom surfaces of both sides of the buffer frame 14. The bottom ends of the limiting slide plates 18 extend to the inside of the slide bars 19. The limiting slide plates 18 are slidably connected to the slide bars 19, which facilitates the limiting of the movement of the buffer frame 14 and the connecting plate 10, preventing the buffer frame 14 and the connecting plate 10 from rotating with the screw 9, thereby ensuring the operation of the device.

[0027] Furthermore, reinforcing plates are fixedly installed on both sides of the adjustment frame 12, and the reinforcing plates are fixedly connected to the sides of the vehicle body 1, so as to facilitate the reinforcement of the adjustment frame 12 and improve the connection strength between the adjustment frame 12 and the vehicle body 1. The telescopic length of the hydraulic rod 2 is greater than the upper and lower lengths of the rear baffle 6 and less than the upper and lower lengths of the rotating groove, so as to prevent the hydraulic rod 2 from conflicting with the rear baffle 6 and the rotating groove when working, thereby affecting the normal operation of the device.

[0028] Working principle: When the unmanned transport vehicle is used, the hydraulic rod 2 is first started to drive the placement platform 3 to rise upward, so that the goods can be placed on the placement platform 3. When the goods are placed, the hydraulic rod 2 is started again to drive the placement platform 3 to move downward and contact the auxiliary support seat 7 above the vehicle body 1. The placement platform 3 is supported by the auxiliary support seat 7 to improve the stability and load-bearing effect of the placement platform 3. At the same time, when the placement platform 3 moves downward, it will drive the gear 11 to rotate on the rack 13, drive the screw rod 9 to rotate, and drive the buffer frames 14 on both sides to move toward the center of the placement platform 3, which is convenient for driving The buffer baffle 16 moves to squeeze and fix the goods on the placement table 3, reducing the shaking of the goods when the device moves, reducing the collision damage between the goods, and improving the stability of the device during transportation. When transported to the destination, the hydraulic rod 2 is started to lift the placement table 3, which will drive the rack 11 to rotate, and drive the two buffer baffles 16 to open and separate from the goods. At the same time, the height of the placement table 3 is flush with the rear baffle 6, which is convenient for unloading the goods on the placement table 3. By arranging a rotating roller 5 on the placement table 3, the friction between the surfaces of the placement table 2 between the goods can be reduced during unloading, which is more convenient for unloading of goods.
