The rotating disc 23 includes a rotating bearing 20 installed in the center of the fixed plate 21. The upper end of the rotating bearing 20 is connected to a rotatable bearing cover plate 19. The cargo compartment bracket plate 5 is fixedly connected to the bearing cover plate 19. A positioning structure is also provided between the fixed plate 21 and the cargo compartment bracket plate 5. In this embodiment, the positioning structure includes a spring positioning pin 22 provided at one end of the fixed plate 21. The upper end of the spring positioning pin 22 is spherical, and the lower end of the spring positioning pin 22 is a hollow structure capable of accommodating a spring. The lower end of the spring positioning pin 22 is provided in a countersunk hole provided on the fixed plate 21 through a spring. The spring positioning pin 22 cooperates with the pin hole provided at the bottom of the cargo compartment bracket plate 5 for positioning. In the present invention, the cargo compartment bracket plate 5 can rotate under the action of an external force, thereby driving the cargo compartment 18 to rotate to a suitable working position for loading and unloading operations. When the cargo compartment bracket plate 5 drives the cargo compartment 18 to rotate under the action of an external force, it presses the spring positioning pin 22 downward. When the pin hole on the cargo compartment bracket plate 5 rotates to the position of the spring positioning pin 22, the spring positioning pin 22 springs up and extends into the pin hole, positioning the cargo compartment bracket plate 5. The cargo compartment bracket arm 6 is a scissor-type structure. The bracket arms of the cargo compartment bracket arm 6 are connected by a bracket arm shaft 13. The lower end of one of the bracket arms of the cargo compartment bracket arm 6 is hingedly connected to the vehicle frame 12, and its upper end is slidably connected to the bottom of the fixed plate 21.

One end of the push plate cylinder 2 is connected to the cylinder bracket 1 fixed at the front end of the cargo compartment 18, and the other end of the push plate cylinder 2 is connected to the material push plate 3. The push plate cylinder 2 drives the material push plate 3 to move within the cargo compartment, thereby pushing the material inside the cargo compartment toward the rear end for easy unloading. A discharge port is provided at the rear end of the floor of the cargo compartment 18. A discharge barrel 16 is installed at the bottom of the cargo compartment 18 and connected to the discharge port. A discharge switch 17 is installed on the discharge barrel 16, and the opening of the discharge port can be controlled by the discharge switch 17. When the cargo compartment contains liquid material, it can be discharged through the discharge barrel 16, and the discharge amount can be controlled by the discharge switch 17. A multifunctional converter assembly 10 is provided on the vehicle frame 12. The oil inlet and outlet of the bracket arm cylinder 7 and the oil inlet and outlet of the cargo box thrust cylinder 4 are respectively connected to the corresponding oil inlet and outlet on the multifunctional converter assembly 10 through oil pipes. The multifunctional converter assembly 10 is the existing technology. The interior of the multifunctional converter assembly 10 is mainly composed of a converter control internal structure I 101 and a converter control internal structure II 102. The valve stem positions of the converter control internal structure I 101 and the converter control internal structure II 102 both have gear position I and gear position II. The converter control internal structure I 101 is provided with an oil inlet I 1014, an oil inlet II 1015, an oil inlet 1017 for the connecting bracket arm cylinder, and an oil inlet 1018 for the connecting cargo compartment thrust cylinder.

The multi-function converter assembly 10 is equipped with joysticks I8 and II9, which are connected to the valve stems 1011 and 1021 of the converter control internal structure I101 and converter control internal structure II102, respectively. The lifting, lowering, and tilting of the cargo box are controlled by joysticks I8 and II9 on the multi-function converter assembly 10.

[0024] The working process of this utility model:

[0025] When stationary, operating handle I8 is in neutral. To raise cargo box 18, move operating handle I8 to position A'. The converter activates, transferring hydraulic oil to multi-function converter assembly 10. The converter transmits oil pressure to bracket arm cylinder 7, raising the cargo box support plate 5 (the height depends on the work requirements). Once raised to a certain height, cargo box 18 also reaches a certain height, allowing construction operations such as unloading bricks, tiles, sand, and gravel to proceed at this height. If cargo is difficult to unload and the cargo box 18 requires a certain tilt angle, move operating handle I8 to position B'. Hydraulic oil is then transferred from multi-function converter assembly 10 to cargo box thrust cylinder 4, which pushes the rod forward, tilting cargo box 18 to the desired angle. Returning operating handle I8 to its original position stops the lifting height and tilting angle of cargo box 18. Within the controllable range, the cargo box can be positioned at any desired height and tilt angle according to user needs by manipulating the control handle I8. To lower the cargo box 18, move the control handle II9 to the C' position. This activates the converter, which allows hydraulic oil to flow through the outlet of the support arm cylinder 7, through the oil pipe, and back to the tank via the control handle. The cylinders operate to simultaneously lower the cargo box support plate and the cargo box. The rod of the support arm cylinder 7 shortens to its initial position, and the cargo box support plate and the cargo box simultaneously descend to their initial height. To shift the cargo box 18 from a tilted position to a horizontal position, move the control handle II9 to the D' position. This activates the converter, which allows hydraulic oil to flow through the outlet of the cargo box thrust cylinder 4, through the oil pipe, and back to the tank via the control handle. The cylinders gradually shift the cargo box from a tilted position to a horizontal position. The tilt angle of the cargo box can be adjusted to either horizontal or tilted positions as needed. Within the controllable range, the control handle of the converter can be used to maintain the cargo box at the desired height and tilt angle.

[0026] It should be noted that, since the present invention has a rotation function, during the process of loading and unloading, the cargo compartment should first be horizontally rotated to a suitable working position before the loading and unloading operation can be carried out.

[0027] When the cargo compartment contains damp, lumpy or other materials that are difficult to unload, the material push plate 3 can be pushed by the push plate cylinder 2 to move the material backward for easy unloading.

[0028] When the cargo compartment contains liquid material, it can be unloaded through the unloading barrel 16 and unloading switch 17 at the rear end of the cargo compartment.

[0029] The other parts of this embodiment are all existing technologies and will not be described in detail here.
