Background

Considering the types and scales of fruits in China, the area of mountainous and hilly areas is wide, most of the fruit trees are planted, the area of an orchard in western areas only reaches 286 hectares, the area accounts for 31 percent of the whole country, and the total yield of the fruits is 1837 million tons. High labor force is inevitably needed to harvest fruits at the back of high yield, although the fruit picking is not difficult, the fruit picking is only easy to pick the fruits near the ground, and the picking difficulty is very high for the fruits at the higher parts of the fruit tree, because generally, fruit growers use ladders, stools or climbing trees for the fruits at the parts, so that many dangerous factors exist, and the potential safety hazard is very large; moreover, the fruit growers can consume much physical strength by circulating back and forth. With the rapid development of the manufacturing industry in China and the great improvement of the popularization degree of agricultural mechanization, the mechanical picking is a necessary development trend to replace manual operation.

The fruit picking at the present stage mainly adopts the following modes:

the first type is a type with extremely high technology content and autonomous action function, but the price is high, so that the type is not suitable for small orchards in hilly lands;

secondly, the safety risk is large by means of a ladder and hands, the radius of manual operation is small, the same fruit tree needs to be picked in a plurality of positions, and time and labor are wasted.

Thirdly, the current stage is a mechanical hand-held picking tool which grabs the fruit to be picked by a paw. The disadvantages are: 1) the fruit can be picked off only by rotating and pulling the fruit, so that the operation steps are increased; 2) the fruit in the high air is difficult to position, and the picking difficulty is increased.

Therefore, a simple fruit picking device is designed to solve the problems.
