[0002] Southwest my country is a region with a large mountainous area. A large portion of arable land is located in mountainous terrain, characterized by rugged terrain, ravines, fragmented land, and steep slopes. For a long time, the harvesting and transportation of crops—including grain (seed corn, rice, and sorghum), feed (silage corn, sweet sorghum, and hybrid pennisetum), and cash crops (peppers, Chinese medicinal herbs, tea, and flue-cured tobacco)—in this region has relied primarily on manual labor. This labor-intensive process results in extremely low harvesting efficiency, severely restricting the efficiency and profitability of the agricultural sector. Furthermore, injuries and damage to vehicles and personnel caused by the narrow and steep paths used by human-operated tricycles, rickshaws, and conventional transport vehicles in mountainous terrain are common. Therefore, there is an urgent need to develop a simple, safe, high-capacity, and durable transport vehicle suitable for mountainous terrain.

[0024] See Figure 1-7 The trolley system 1 is a kind of mountain transport vehicle, comprising a crawler chassis and a carriage 1 arranged on the crawler chassis. The crawler chassis comprises two symmetrically arranged cross beams 2, annular crawler tracks 3, load-bearing wheels 4, supporting wheels 5, driving wheels 6, guide wheels 7, driving motors 8 and adjusting mechanisms 9. The driving wheels 6 and guide wheels 7 are rotatably arranged at both ends of the cross beam 2. One end of the cross beam 2 is provided with an adjusting mechanism 9 for adjusting the height of the guide wheels 7.

[0026] The preferred adjustment mechanism 9 includes an adjusting electric cylinder 901 and an adjusting frame 902. One end of the adjusting frame 902 is rotatably arranged on the end of the beam 2 away from the driving wheel 6 through an axle pin, and the guide wheel 7 is rotatably arranged on the free end of the adjusting frame 902 through an axle pin. There are two adjusting electric cylinders 901 and they are rotatably arranged on both sides of the beam 2. The output ends of the two adjusting electric cylinders 901 are respectively rotatably connected to the adjusting frames 902. A lifting assembly 12 for lifting the tugboat is provided on the top of the beam 2. The two adjusting electric cylinders 901 are respectively connected to the controller. The remote control is provided with a control button for the adjusting electric cylinder 901, which can realize adjusting the height of the guide wheel 7 through the adjusting mechanism 9 to adapt to the steep slope when the road surface is steep, so that it can pass smoothly.

A plurality of first shock absorber frames 1301 are evenly spaced and rotated on the lower side of the crossbeam 2, and the plurality of first shock absorber frames 1301 are all tilted downward. The lower ends of the plurality of first shock absorber frames 1301 are all rotatably provided with load-bearing wheels 4. The lower parts of the plurality of first shock absorber frames 1301 and the crossbeam 2 are respectively connected to the first shock absorber spring 1302.

The load-bearing wheel 4 on the lower side of the driving wheel 6 is arranged at the lower end of the second shock absorber frame 1401. The design of the first shock absorber 13 and the second shock absorber 14 makes it easier to become more stable through the shock-absorbing effect of the first shock absorber spring 1302 and the second shock absorber spring 1402 themselves and the ups and downs when driving on bumpy roads, thereby avoiding rollover.

[0028] Preferably, a lifting assembly 12 is respectively provided on the top of the two beams 2, and the lifting assembly 12 includes a mounting frame 1201, a first lifting electric cylinder 1202 and a U-shaped frame 1203. The mounting frame 1201 is fixedly provided on the top of the beam 2, the first lifting electric cylinder 1202 is fixedly provided on the beam 2 inside the mounting frame 1201, the U-shaped frame 1203 is fixedly provided on the top of the output end of the first lifting electric cylinder 1202, the supporting wheel 5 is rotatably provided in the U-shaped frame 1203, the first lifting electric cylinder 1202 is connected to the controller, and a control button for the first lifting electric cylinder 1202 is provided on the remote controller. When in use, controlling and starting the first lifting electric cylinder 1202 can control the lifting and lowering of the U-shaped frame 1203, so that the annular crawler 3 can be tensioned.

[0029] Preferably, guide rods 1204 are provided vertically downward on both sides of the lower end of the U-shaped frame 1203, and holes suitable for the guide rods 1204 to pass through are opened vertically downward on both sides of the mounting frame 1201. The design of the guide rods 1204 makes the U-shaped frame 1203 more stable when lifting.

[0030] The preferred carriage 1 consists of four side panels and a bottom panel. The bottom panel is horizontally arranged on the top of the frame 10.

The upper ends of the two side panels on the opposite sides are respectively rotated with lock hooks 15, and the upper ends of the other two side panels are respectively horizontally provided with lock rods. The lock rods are matched with the lock hooks 15 to make loading and unloading more convenient and easy.

[0031] Preferably, two second lifting cylinders 16 are symmetrically provided on one side of the frame 10, and the two second lifting cylinders 16 are both rotatably connected to the frame 10. The output shaft ends of the two second lifting cylinders 16 are respectively rotatably connected to the bottom end of the carriage 1. The bottom end of the carriage 1 is rotatably set on the frame 10 away from the two second lifting cylinders 16. The second lifting cylinder 16 is connected to the controller, and a control button for the second lifting cylinder 16 is provided on the remote control. The setting of the second lifting cylinder 16 makes it convenient to lift the carriage 1 by controlling the second lifting cylinder 16 to unload the crops inside when transporting to the destination, thereby reducing unloading time and improving efficiency.

[0032] The preferred annular crawler track 3 is made of rubber material, which can further enhance the adaptability to rough roads.

[0033] The working principle of the transport vehicle of the present invention is as follows: during transportation, the control button on the remote controller is used to control the start of the two drive motors 8 to drive the two drive wheels 6 to rotate and drive the annular crawler 3 to rotate forward. When the slope is too steep and the annular crawler 3 cannot pass, the two adjusting cylinders 901 are controlled to start working, so that they pull the adjusting frame 902 to move the two guide wheels 7 upward. At the same time, the first lifting electric cylinder 1202 is started to drive the supporting wheel 5 to move upward so that the annular crawler 3 can be tensioned. When the road surface is bumpy during transportation, the shock-absorbing effect of the shock-absorbing springs of the first shock absorber 13 and the second shock absorber 14 can make the load-bearing wheel 4 jump up and down, thereby making the transport vehicle transported smoothly and avoiding its overturning. When transported to the destination, the locking hooks 15 on both sides are opened and the second lifting electric cylinder 16 is controlled to start so that it can lift the carriage 1 so that the crops transported in it can be dumped out, reducing unloading time and improving efficiency.
