All 115 are fixedly connected to the body 114, the body 114 is rotatably connected to the axle 116, the two gripping frames 120 are fixedly connected to the door 119, the door 119 is rotatably connected to the door axle 118, the door axle 118 is fixedly connected to the body 114, the abutment plate 122 is fixedly connected to the shock-absorbing base plate 121, the shock-absorbing base plate 121 is fixedly connected to the frame 110, and the unloading plate 109, under the sliding support of multiple pulleys 108, achieves rapid unloading through gravity during unloading. Automatic unloading can be completed simply by raising the carriage 102, which is convenient and simple to operate. This design has a simple structure, is easy to produce, and solves the problem that goods are easily unable to be unloaded quickly and the unloading rate is slow due to the tilt angle of the carriage 102 during the unloading process.

[0023] The shock absorption assembly 105 is located above the frame 101, the movable door 103 is located on one side of the carriage 102, the carriage 102 is located above the frame 101, the unloading plate 109 is located above each pulley 108, each pulley 108 is located around the corresponding positioning rod 107, each positioning rod 107 is located above the inner frame 106, the inner frame 106 is located at the inner bottom of the carriage 102, each pulley 108 rotates around the corresponding positioning rod 107, but does not move laterally. When the side of the carriage 114 near the side seat 117 is raised, the unloading plate 109 slides down due to gravity, thereby causing the carried material to slide, greatly improving the unloading rate. Furthermore, no partitions are set inside the carriage 114 to separate the goods, so it can also support loading large-volume goods, avoiding the space shortage caused by setting partitions.

[0024] Secondly, the cylinder 113 is located above the movable block 112, the movable block 112 is located around the horizontal axis 111, the horizontal axis 111 is located on one side of the frame 110, the side seat 117 is located on one side of the compartment 114, the compartment shaft 116 is located on the other side of the compartment 114, both limiting plates 115 are located on the inner wall of the compartment 114, the compartment 114 is located around the compartment shaft 116, the lower side of the side seat 117 has a rotating head that is compatible with the output end of the cylinder 113, and the movable block 112 can rotate freely under the support of the horizontal axis 111. Therefore, when the cylinder 113 drives the side seat 117 to move upward and rise, the movable block 112 can also make adaptive changes according to the changes of the cylinder 113, avoiding the situation where the side seat 117 moves in an arc after rising and the cylinder 113 can no longer support it.

[0025] Meanwhile, both gripping frames 120 are located on one side of the door body 119, the door body 119 is located around the door hinge 118, the door hinge 118 is located on one side of the box body 114, the abutment plate 122 is located above the shock-absorbing base plate 121, and the shock-absorbing base plate 121 is located above the frame 110. When the semi-trailer is unloading, first open the switch holding the door body 119, and rotate the door body 119 downwards via the door hinge 118. Then, the cylinder 113 is activated, and the output end of the cylinder 113 is rotatably connected to the lower side of the side seat 117, gradually raising the side seat 117 and the box body 114 under gravity. In this case, the unloading plate 109 and the material it carries slide out of the compartment 114 through the sliding of multiple pulleys 108. During unloading, the operator stays away from the discharge end of the compartment 114. Since the unloading plate 109 is slidably connected to each pulley 108, the resistance is small, and the material can be unloaded quickly. After unloading is completed, the cylinder 113 is reset, and the compartment 114 is horizontal. The operator then places the unloading plate 109 back above the inner frame 106 and aligns it with the two limiting plates 115. The unloading plate 109 is then slid back under the two limiting plates 115. Finally, the door 119 is flipped to close, completing the unloading operation.

[0026] In this embodiment, each pulley 108 rotates around the corresponding positioning rod 107, but there is no lateral movement. When the side of the box 114 near the side seat 117 is raised, the unloading plate 109 slides down due to gravity, thereby causing the carried material to slide, greatly improving the unloading rate. Furthermore, no partitions are provided inside the box 114 to separate goods, thus supporting the loading of larger goods and avoiding the space constraints caused by partitions. The lower side of the side seat 117 has a rotating head that matches the output end of the cylinder 113, and the movable block 112 can rotate freely under the support of the horizontal axis 111. Therefore, when the cylinder 113 drives the side seat 117 to move upwards, the movable block 112 can also adapt to the changes in the cylinder 113, avoiding the situation where the side seat 117 moves in an arc after being raised and the cylinder 113 can no longer provide support. When unloading from the semi-trailer, first open... The switch holding the door 119 rotates the door 119 downwards via the door hinge 118. Then, the cylinder 113 is activated, and its output end is rotatably connected to the lower side of the side seat 117, gradually raising the side seat 117 and the chamber 114. Under gravity, the unloading plate 109 and the material it carries slide out of the chamber 114 via the sliding of multiple pulleys 108. During unloading, the operator moves away from the discharge area of ​​the chamber 114. At the end, since the unloading plate 109 is slidably connected to each of the pulleys 108, the resistance is small, and the material can be unloaded quickly. After unloading is completed, the cylinder 113 is reset, the box 114 is horizontal, and the worker then places the unloading plate 109 back above the inner frame 106 and aligns the two limiting plates 115. The unloading plate 109 is then slid back under the two limiting plates 115, and finally the door 119 is flipped to close, completing the unloading operation.
