[0011] As an improvement, the adjustment mechanism includes a second hydraulic telescopic rod, an adjustment groove, and a connecting rod;

[0012] The adjustment groove is located on the top surface of the lifting platform. After the hydraulic telescopic rod is fixed inside the adjustment groove at one end, the other end is connected to a slider that is slidably connected to the adjustment groove. After one end of the connecting rod is hinged to the top surface of the slider, the other end is hinged to the bottom surface of the inclined feeding plate.

[0013] As an improvement, the extension frame is an open mesh frame structure. The outer wall of the vehicle frame has a through slot that communicates with the storage slot. A push plate that passes through the through slot and extends to the outside of the vehicle frame is connected to the extension frame. The positioning mechanism fixes the push plate to fix the position of the extension frame.

[0014] As an improvement, the positioning mechanism includes a positioning bolt and a positioning threaded hole;

[0015] The positioning bolts pass through the push plate and are threadedly connected to the positioning threaded holes pre-set on the outer wall of the vehicle frame. Multiple positioning threaded holes are evenly arranged along the extension direction of the extension frame, and a pair of positioning mechanisms are mirrored.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. By using a lifting mechanism to raise vegetables to an appropriate height, workers are spared from frequent bending and lifting movements, which reduces labor intensity and improves loading efficiency.

[0018] 2. By adjusting the angle of the tilting feed plate, vegetables can be smoothly slid into the truck bed, speeding up the loading process;

[0019] 3. The extension frame can be adjusted according to the size of the vegetables to ensure maximum loading capacity while maintaining cargo stability. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Example 1

[0028] Combined with appendix Figure 1 As shown, a trolley for loading vegetables for wholesale includes a vehicle frame 1 and casters 2. Four casters 2 are installed at the bottom of the vehicle frame 1, at least two of which are equipped with braking mechanisms. Vegetables are placed inside the vehicle frame 1 and moved by the casters 2 to carry out loading work. The braking mechanism can improve the stability of the device during the loading process.

[0029] Example 2

[0030] Based on Example 1, combined with Appendix Figure 2-4 As shown, it also includes a lifting mechanism and a lifting platform 3; after the top of the vehicle frame 1 is opened, the lifting platform 3 is set inside the vehicle frame 1, and the lifting mechanism drives the lifting platform 3 to move up and down in the vertical direction to adapt to different loading height requirements; the lifting mechanism includes a first hydraulic telescopic rod 6 and a lifting limit groove 7; after the first hydraulic telescopic rod 6 is fixed to the bottom inside the vehicle frame 1, the top is fixedly connected to the lifting platform 3, and the inner walls around the vehicle frame 1 are provided with lifting limit grooves 7 that are slidably connected to the lifting platform 3;

[0031] Through the above structure, the lifting mechanism is used to lift the vegetables on the lifting platform 3 to an appropriate height, avoiding the frequent bending and lifting movements of workers, reducing the intensity of work and improving loading efficiency.

[0032] The extension frame 4 has open-top storage slots 5 on all four sides of the vehicle frame 1. The extension frame 4 is slidably installed in the storage slots 5 and fixed in position by a positioning mechanism to meet the loading requirements of different goods. The extension frame 4 is a mesh frame structure with open top and bottom. The outer wall of the vehicle frame 1 has a through slot 13 that communicates with the storage slots 5. A push plate 14 is connected to the extension frame 4, extending through the through slot 13 to the outside of the vehicle frame 1. The positioning mechanism fixes the push plate 14 to fix the position of the extension frame 4. The positioning mechanism includes a positioning bolt 15 and a positioning threaded hole 16. The positioning bolt 15 passes through the push plate 14 and is threadedly connected to the positioning threaded hole 16 on the outer wall of the vehicle frame 1. Multiple positioning threaded holes 16 are evenly arranged along the extension direction of the extension frame 4, and a pair of positioning mechanism are mirrored. This allows for easy adjustment of the loading volume of the device according to the size of the vegetables, ensuring maximum loading capacity while maintaining the stability of the goods.

[0033] It also includes an inclined feeding plate 8, which is hinged to the top surface of the lifting platform 3. After the vegetables are placed on the upper surface of the inclined feeding plate 8, the tilt angle of the inclined feeding plate 8 is adjusted by the adjustment mechanism to control the speed and direction of the vegetables sliding down. The adjustment mechanism includes a second hydraulic telescopic rod 9, an adjustment groove 10, and a connecting rod 11. The adjustment groove 10 is opened on the top surface of the lifting platform 3. After the hydraulic telescopic rod is fixed inside the adjustment groove 10 at one end, the other end is connected to a slider 12 that is slidably connected to the adjustment groove 10. After one end of the connecting rod 11 is hinged to the top surface of the slider 12, the other end is hinged to the bottom surface of the inclined feeding plate 8. By adjusting the angle of the inclined feeding plate 8 through the adjustment mechanism, the vegetables can be smoothly slid into the truck bed, speeding up the loading speed.

[0034] In practical implementation, the vegetables are first placed on the inclined feeding plate 8 inside the vehicle frame 1. At this time, the inclined feeding plate 8 is in a horizontal state. The loading volume of the device is adjusted according to the size of the vegetables. The extension frame 4 is pulled to move it out to different lengths. After reaching the required size, the positioning bolt 15 is used to connect the push plate 14 through the corresponding positioning threaded hole 16, so that the vegetables can be loaded into the vehicle frame 1. Finally, the vehicle frame is pushed to move it to the loading position. The braking mechanism is used to position the caster 2. Then, the first hydraulic telescopic rod 6 can continuously push the vegetables upward. After pushing them to the loading position, the second hydraulic telescopic rod 9 pushes the connecting rod 11 to rotate, so that the inclined feeding plate 8 tilts towards the loading position and pushes the vegetables out for feeding.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
