Modern agricultural machinery equipment is not only a strategic key point of modern agricultural development and country plain, but also an important component for manufacturing strong countries and science and technology. The practical requirement of reducing the red blood of rural population, the grading requirements of the appearance (color, fruit shape, flaws and textures), size and internal quality (sugar degree and moisture) of fruits and vegetables such as the upgrading of agricultural product consumer market, and the automatic intelligent fruit and vegetable sorting equipment accords with the national policy guidance and is imperative to develop. Because the small-particle fruits and vegetables are small in size and light in weight, the small-particle fruits and vegetables are more suitable for carrying out operations such as transportation, sorting and packaging by using an automatic machine compared with fruits and vegetables with large mass. The belt conveyor is one of important automatic equipment for conveying small-particle fruits and vegetables.
