[0021] The device is placed on the side close to the semi-trailer, and the cylinder 9 pushes the guide plate 16 to rotate through the elastic support plate 10, so that the guide plate 16 faces the truck bed of the semi-trailer. The staff puts the box into the guide plate 16 on the car, and the box slides down along the guide plate 16 and slides onto the conveyor belt 72 on the first mounting frame 5. At this time, the conveyor belt 72 rotates driven by the first motor 73, driving the box to move. The box moves to one end of the conveyor belt 72, detaches from the conveyor belt 72, slides along the arc plate 11, and falls on the conveyor belt 72 on the second mounting frame 6. The conveyor belt 72 is in a closed state. After the box falls on the conveyor belt 72, the drive motor 13 is turned on, and the second mounting frame 6 is driven to descend through the gear 14 and the rack 15. The sub-frames descend synchronously, and at this time the staff continues to move the boxes and put them into the guide plate 16. At this time, the second box, after being transported, falls on the top of the box on the second mounting frame 6 for stacking, and so on. The boxes are stacked vertically on the second mounting frame 6. When the stacking reaches a certain height, the conveyor belt 72 on the second mounting frame 6 is opened, so that the stacked boxes slide out from the surface of the conveyor belt 72. The staff on the ground transfers the stacked boxes by tools such as carts, which is more convenient. Multiple boxes can be moved at one time, which is more labor-saving. By setting the sliding seat 4, the staff only needs to put the box into the guide plate 16, and the device can move the box down the bucket and automatically stack it at the same time, which is more labor-saving and convenient for unloading.

[0022] The upper surface of the bottom plate 1 is fixedly connected to the vertical plate 17, one side of the vertical plate 17 is fixedly connected to the electric push rod 18, the telescopic rod of the electric push rod 18 is fixedly connected to the pushing plate 19, the upper surface of the bottom plate 1 is fixedly connected to the support plate 20, the support plate 20 is provided with a square through groove, the support plate 20 is rotatably connected to the rubber column 21, the support plate 20 and the vertical plate 2 are fixedly connected to the placement table 22, the upper surface of the placement table 22 is fixedly connected to the fixed plate 23, the fixed plate 23 is slidably connected to the sliding rod 24, one end of the sliding rod 24 is fixedly connected to the square plate 25, and the square plate 25 and the fixed plate 23 are fixedly connected with a spring 26.

[0023] When the boxes are gradually stacked, the four sides of the boxes are supported, namely the push plate 19, the rubber column 21, the square plate 25 and the vertical plate 2, which can prevent the boxes from tilting and collapsing when stacking. When the boxes are stacked, the conveyor belt 72 on the second mounting frame 6 is turned on to transport the boxes. At this time, the electric push rod 18 pushes the push plate 19 to move, so that the push plate 19 keeps pushing the box to move. The other side of the box pushes the square plate 25 to move, and the spring 26 is compressed. The box begins to move slowly from the conveyor belt 72 to the placement table 22. Then the push plate 19 is reset, and the staff transfers the boxes on the placement table 22. The force of the spring 26 when compressed is less than the friction between the box and the placement table 22, and only acts on the sliding rod 24 to reset. When moving, the push plate 19 keeps pushing the box, and keeps supporting the box when moving, so as to prevent the box from scattering and tilting when moving.

[0024] The working principle and use process of the utility model are as follows: the device is placed on a side close to the semi-trailer, the cylinder 9 pushes the guide plate 16 to rotate through the elastic support plate 10, so that the guide plate 16 faces the bucket of the semi-trailer, the staff puts the box into the guide plate 16 on the car, the box slides down along the guide plate 16, the conveyor belt 72 rotates under the drive of the first motor 73, drives the box to move, the box moves to one end of the conveyor belt 72, separates from the conveyor belt 72, slides along the arc plate 11, and falls on the conveyor belt 72 on the second mounting frame 6, the drive motor 13 is turned on, and the gear 14 and rack 15 are driven The second mounting frame 6 is driven to descend, and the box descends synchronously. At this time, the staff continues to move the box and put it into the guide plate 16. At this time, the second box falls on the top of the box on the second mounting frame 6 after being transported, and is stacked. When the boxes are stacked, the conveyor belt 72 on the second mounting frame 6 is turned on to transport the boxes. At this time, the electric push rod 18 pushes the push plate 19 to move, so that the push plate 19 keeps pushing the box to move, and the other side of the box pushes the square plate 25 to move, the spring 26 is compressed, and the box begins to move slowly from the conveyor belt 72 to the placement table 22, and then the push plate 19 is reset.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
