Description

A roller comb and scissors litchi picking machine

technical field

The invention relates to picking machine technology, in particular to a roller comb and scissor litchi picking machine.

Background technique

Litchi is a subtropical fruit with Chinese characteristics. It is mainly distributed in Guangdong, Guangxi, Fujian, Hainan and other provinces. Its planting area and total output both rank first in the world. In recent years, Guangdong has actively promoted pollution-free and standardized lychee production technology throughout the province, and produced a large number of products that meet the standards, which has improved the market competitiveness of lychees. However, at present, lychee picking is mainly manual picking, which requires a lot of labor, and the migration of farmers to work in cities has further caused labor shortages. Litchi picking has become a major factor restricting the development of litchi industry, and the cost of picking has become one of the main expenses of litchi growers. In order to reduce the labor intensity of picking, reduce the cost of litchi production, and improve the efficiency of picking, litchi picking machinery should be popularized. Picking machinery can improve the efficiency of litchi picking operations, greatly save labor costs, and improve the economic benefits of fruit farmers. Therefore, litchi picking machinery has important application value and practical significance.
