[0048] Insert rod 18: Plugged into the base plate 12, used for installing the steel wire rope 19 to form a fence to prevent watermelons from rolling during transportation.

[0049] Steel wire rope 19: is arranged on the insertion rod 18 to form a fence, and can be wound with a protective rope to improve the protection of the watermelon.

[0050] Here’s how it works:

[0051] 1. Driving part

[0052] The operator controls the bogie 6 by pulling the handle 7 , and the bogie 6 drives the adjustment frame 8 and the connecting frame 9 to move, thereby adjusting the direction of the support rod 10 and the front wheel 11 .

[0053] When the transport device is pushed, the rear wheel 4 rotates under the action of the shaft 3 to provide the power for advancement. The front wheel 11 is controlled by the steering system to achieve flexible steering, so that the transport device can travel smoothly on different roads and spaces.

[0054] 2. Buffer part

[0055] When the transport device is traveling on the road and encounters bumps or uneven places, the bottom plate 12 will be subjected to impact force from the ground.

[0056] The bottom plate 12 transmits the impact force to the pad 13, and the large spring 14 between the pads 13 first works to absorb part of the impact force by compression and extension. The large spring 14 is thick at both ends and narrow in the middle, which may make it more stable when subjected to force and better able to withstand and disperse the impact force.

[0057] At the same time, the relative sliding between the large sleeve 15 and the small sleeve 16 and the support spring 17 inside the large sleeve 15 will further buffer the impact force. The small sleeve 16 slides inside the large sleeve 15, and the support spring 17 is compressed or stretched, which together play a shock-absorbing role, reducing the vibration transmitted to the bottom plate 12, thereby protecting the watermelon placed on the bottom plate 12 from damage.

[0058] 3. Protection part

[0059] The insertion rods 18 inserted into the bottom plate 12 and the steel wire ropes 19 arranged on the insertion rods 18 form a fence to prevent the watermelons from rolling down during transportation.

[0060] The protective rope wound around the steel wire rope 19 can further enhance the protective effect of the fence and prevent the watermelon from being scratched or damaged by direct contact with the steel wire rope 19.

[0061] In summary, the short-distance watermelon transport device realizes the functions of flexible driving, effective buffering and reliable protection through reasonable structural design, which provides convenience and guarantee for the short-distance transportation of watermelons.

[0062] like Figure 2As shown, in some embodiments, the front wheel 11 and the rear wheel 4 are both pneumatic tires; the pneumatic tires are filled with air and have good elasticity. When the transport device encounters an uneven road surface during driving, the pneumatic tires can absorb and buffer the vibration through their own deformation, reducing the impact force transmitted to the transport device body and the watermelons placed thereon. This helps to protect the watermelons from damage caused by vibration during transportation and improves the stability and safety of transportation.

[0063] like Figure 3 As shown, in some embodiments, the support rod 10 is rotatably connected to a portion of the mounting frame 5; when the transport device needs to turn, the front wheel 11 can change direction more flexibly because the support rod 10 is rotatably connected to the mounting frame 5. This design allows the operator to easily control the direction of the transport device, especially in narrow spaces or complex road conditions, and can perform steering operations more accurately.

[0064] like Figure 4 As shown, in some embodiments, the large spring 14 is designed to be thick at both ends and narrow in the middle; this special shape design makes the large spring 14 more stable when subjected to force. When the transport device encounters bumps or vibrations during driving, the thicker parts at both ends of the large spring 14 can better withstand and disperse the pressure from the bottom plate 12, reducing the shaking and deviation of the spring.

[0065] like Figure 4 As shown, in some embodiments, a support spring 17 is installed inside the large sleeve 15, and the top is fixedly connected to the small sleeve 16; when the transport device encounters bumps or vibrations during driving, the bottom plate 12 will transfer the impact force to the small sleeve 16. The small sleeve 16 slides inside the large sleeve 15, and the support spring 17 inside the large sleeve 15 will be compressed to absorb part of the impact force.

[0066] like Figure 2 As shown, in some embodiments, a protective rope is wound around the steel wire rope 19; the protective rope can play a buffering role. When the watermelon collides with the fence, the protective rope can absorb part of the impact force and reduce damage to the watermelon. Compared with a simple steel wire rope 19, the soft material of the protective rope can better protect the surface of the watermelon from scratches and collisions.

[0067] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
