Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

During the process, the first telescopic motor 12 and the second telescopic motor 121 will adjust the length of the multiple telescopic shafts 13, so that the second conveyor belt 15 and the third conveyor belt 16 are extended. At the same time, the driving block 31 adjusts the angle of the universal wheel 32 accordingly so that the wheel axle is always perpendicular to the ground; this step drives the multiple conveyor belts to expand or retract by the first telescopic motor 12 and the second telescopic motor 121, so that they are expanded when needed and retracted when not in use, which is conducive to reducing the equipment footprint, reducing the difficulty of equipment storage, providing convenience for the use and storage of the equipment, and making the movement and transportation of the equipment more efficient.

[0024] like Figure 1 、 Figure 2 and Figure 4As shown, the pallet 4 is connected to the loading platform 20 by bolts; during operation, when the device is in use, the loading platform 20 can be disconnected from the pallet 4, and the loading platform 20 can be fixed to a position inside the truck for convenient loading and unloading of goods. Thereafter, when the goods are unloaded, the first telescopic motor 12, the second telescopic motor 121 and the drive block 31 are driven to work. As the second conveyor belt 15 and the third conveyor belt 16 are unfolded, the universal wheel 32 touches the ground, and the equipment is further unfolded until it is fully unfolded. When the device needs to be stored, the first telescopic motor 12 and the second telescopic motor 121 can be controlled to drive the telescopic shaft 13 to retract, and the first conveyor belt 11, the second conveyor belt 15 and the third conveyor belt 16 can be retracted, and then they can be folded and stored; the detachable function of the conveying body provides a solution for a vehicle-mounted unloading device for freight vehicles, which is beneficial to improving logistics unloading efficiency and saving manpower.

[0025] like Figure 1 and Figure 2 As shown, a shock-absorbing plate 22 is provided inside the loading platform 20; a guide rod is fixed to the top of the shock-absorbing plate 22, and the guide rod is slidably connected to the inside of the loading platform 20; a fixing nut 21 is fixed to the top of the guide rod; a spring is fixed between the fixing nut 21 and the loading platform 20; when working, when carrying heavier goods, it is difficult to handle the goods with care, and long-term impact will have an impact on the equipment; this is conducive to alleviating the impact of the equipment on the goods and extending the service life of the equipment.

[0026] like Figure 1 and Figure 3 As shown, a limiting slot 14 is provided on the side of the first conveyor belt 11 corresponding to the second telescopic motor 121; the limiting slot 14 passes through the first conveyor belt 11; a limiting slot 14 is provided on the side of the fixed block 122 corresponding to the second conveyor belt 15; the limiting slot 14 passes through the second conveyor belt 15; the length of the limiting slot 14 is the same as the telescopic shaft 13; the two second telescopic motors 121 are connected to each other by a sliding rod, and the two fixed blocks 122 are also connected by a sliding rod, and the sliding rod is slidably connected to the inside of the limiting slot 14; during operation, when the first conveyor belt 11, the second conveyor belt 15 and the third conveyor belt 16 are expanded or contracted, the sliding of the sliding rod is restricted by the limiting slot 14, so that the two second telescopic motors 121 can maintain synchronous movement and the two fixed blocks 122 can also maintain synchronous movement, thereby preventing uneven contraction and improving the integrity of the equipment convergence and expansion process.

[0027] like Figure 1As shown, the elevator 2 is fixed with a main handrail 5 in the direction away from the first conveyor belt 11; the main handrails 5 correspond to each other; during operation, after unloading is completed and the second conveyor belt 15 and the third conveyor belt 16 are fully converged, the equipment can be moved with the help of the main handrail 5; this provides convenience for the transfer of the equipment and increases the operability of the equipment movement.

[0028] like Figure 1 and Figure 4 As shown, the bottom of the chassis 1 is rotatably connected to a top plate 29; the bottom of the top plate 29 is rotatably connected to a driving wheel 30; the rotation direction of the top plate 29 is parallel to the bottom surface of the chassis 1, and the center of the rotation circle of the top plate 29 is the center of the top plate 29 itself; when working, the driving wheel 30 can move in any direction through the top plate 29, thereby improving the flexibility of the equipment movement and facilitating the transfer and movement of the equipment.

[0029] like Figure 1 and Figure 4 As shown, the surfaces of the driving wheel 30 and the universal wheel 32 are coated with an anti-skid coating; during operation, the anti-skid coating increases the friction of the tire surface, allowing the tire to grip the ground tightly.

At the same time, the driving block 31 adjusts the angle of the universal wheel 32 accordingly so that the wheel axle is always perpendicular to the ground. When the device is in use, the loading platform 20 can be disconnected from the pallet 4, and the loading platform 20 can be fixed to a position inside the truck for loading and unloading goods. Thereafter, when the goods are unloaded, the first telescopic motor 12, the second telescopic motor 121 and the driving block 31 are driven to work. As the second conveyor belt 15 and the third conveyor belt 16 are unfolded, the universal wheel 32 touches the ground, and the equipment is further unfolded until it is fully unfolded. When the device needs to be stored, the first telescopic motor 12 and the second telescopic motor 121 can be controlled to drive the telescopic shaft 13 to retract, and the first conveyor belt 11, the second conveyor belt 15 and the third conveyor belt 16 can be retracted, and then they can be folded and stored. When carrying heavier goods, it is difficult to handle the goods with care, and long-term impact will have an impact on the equipment. The shock absorber unit reduces the impact of the goods. When the first conveyor belt 11, the second conveyor belt 15 and the third conveyor belt 16 are expanded or retracted, the sliding of the slide bar is restricted by the limit groove 14. After unloading is completed and the second conveyor belt 15 and the third conveyor belt 16 are fully retracted, the main body armrest 5 can be used to pull the equipment to move, and the drive wheel 30 can move in any direction through the top plate 29. The anti-slip coating increases the friction of the tire surface, so that the tire grips the ground tightly.
