[0028] See also Figure 1 、 Figure 2 and Figure 3 The material rack 3 is provided with several groups of material boxes 4, transverse moving components 5 and longitudinal moving components 6. Four groups of universal wheels 7 are fixedly connected to the bottom of the material box 4.

[0031] See also Figure 2 The top ends of the front side panel 32 and the rear side panel 33 are respectively fixedly connected with lock buckles 8, which are used to connect and lock the front side panel 32, the rear side panel 33, the right side panel 36 and the fixing frame 35 to prevent the material from accidentally slipping during the lifting process, and at the same time, facilitate the loading of materials when opening.

[0032] See also Figure 1 Four groups of hydraulic cylinders 3 10 are fixedly connected to the top of the mobile vehicle 1. The four groups of hydraulic cylinders 3 10 are located on the periphery of the lifting frame 2. When the hydraulic cylinders 3 10 are extended, the output ends contact the ground, thereby playing a supporting role and improving the stability during material transportation. A traction hook 11 is provided on the side of the mobile vehicle 1. The traction hook 11 is used to connect to a tractor using a traction rope, and is towed by the tractor to move the position.

[0033] Working principle: During use, when the material in the material box 4 is not higher than the fixed frame 35: the staff drives the mobile vehicle 1 or the tractor to drive the mobile vehicle 1 to move, so that the left side plate 34 corresponds to the position where the material needs to be transported, and then controls the hydraulic cylinder 3 10 to extend, so that the output end of the hydraulic cylinder 3 10 contacts the ground for support, and then controls the lifting frame 2 to drive the material rack 3 to rise to the appropriate position, and then controls the hydraulic cylinder 3 10 to extend, so that the base 31 is lifted up on the right side under the action of the two connecting rod groups 37, so that the material box 4 inside the material rack 3 can move to the left under the action of its own gravity, and after lifting the left side plate 34, it slides out of the material rack 3, reducing the labor intensity of the staff in transporting materials.

[0034] When the material in the material box 4 is higher than the fixed frame 35: the staff drives the mobile vehicle 1 or the tractor to drive the mobile vehicle 1 to move so that the opening of the front side plate 32 corresponds to the position where the material needs to be conveyed, and then controls the hydraulic cylinder 3 10 to extend so that the output end of the hydraulic cylinder 3 10 contacts the ground for support, and then controls the motor 51 to start, and drives the roller 53 to rotate through the chain transmission, driving the upper material box 4 to be conveyed horizontally until the material box 4 is above the longitudinal conveying component, and then controls the hydraulic cylinder 1 61 to start and extend, driving the connecting plate 62 and the connecting seat 63 to move left, and pushing the material box 4 out of the material rack 3. At this time, the material box 4 is above the connecting seat 63, and the universal wheels 7 are located on both sides of the connecting seat 63, which can prevent the material from slipping during longitudinal conveying, thereby improving the stability of material conveying. After that, the staff only needs to push the material box 4 to unload the material, avoiding carrying the material one by one, thereby improving the material conveying efficiency and reducing the labor intensity of the staff.
