In recent years there have been breakthroughs in field transport technology in China's mountain orchards, with the main technologies being overhead transport ropeways and rail forms. These two transport technologies provide solutions for the transport of agricultural materials and fruit in mountainous steep-slope orchards, but have the disadvantage of being less mobile. In order to improve the efficiency of transport in gently sloping mountain orchards, it is necessary to design a transport vehicle that is easy to operate and well adapted. In mountainous orchards, the traction of a wheeled vehicle is significantly less than that of a tracked vehicle with a larger grounded area on a sticky soil surface, and the latter's adaptability to complex terrain is significantly better than the former. The latter is also significantly better adapted to the complex terrain. The four unlike tracked transporters are undoubtedly a better choice for short-distance transport in mountain orchards.

(1) According to the characteristics of mountain orchards, a feasible design solution is proposed for the layout of the whole vehicle system in order to solve the problem of poor anti-rollover performance of mountain miniature tracked transporters.

(2) The 3D solid model of the whole vehicle is established, the modular components are virtually assembled, and the kinematic and static simulation analysis is carried out. Through analysis and optimization, the design meets the technical parameters and improves the anti-rollover performance of the whole vehicle.

(3) Compared with the existing orchard transport tools, the four unlike tracked transporters have a strong adaptability to the terrain, and have better passability and driving stability in mountainous terrain without roads. Due to its lower driving speed, it is more suitable for short-distance transportation in mountainous orchards and small-scale orchards, solving the shortcomings of other transportation methods.
