Abstract

The invention discloses a feedback suction type picking head. The picking head comprises a suction pipe, one end of the suction pipe is sealed, and the other end of the suction pipe is sleeved with a suction nozzle made of a rubber material; the suction pipe is separately provided with an air suction opening and a pressure detection opening, and the pressure detection opening is formed between the air suction opening and the suction nozzle; the air suction opening is connected with a negative pressure device through a connector, a pressure sensor is mounted on the pressure detection opening, and both the pressure sensor and the negative pressure device are electrically connected with a controller. A picking method adopting the feedback suction type picking head comprises steps S1-S9. The negative pressure device can dynamically adjust the suction force of a fan of a dust collector so as to adjust the pressure in the suction pipe; since a picking device needs pressure different in intensity under a suction state during picking operation and after picking, target crops are prevented from being damaged. When the suction nozzle is close to the target crops, the picking device enhances the suction force and can suck the target crops within a certain distance, so that the picking device has a large tolerance rate.

Description

technical field [0001] The invention relates to the technical field of picking agricultural products, in particular to a feedback suction-type picking head and a picking method thereof. Background technique [0002] The distance between the north and the south of China is more than 5,500 kilometers, spanning nearly 50 latitudes, and most areas are located in the mid-latitude zone between 20° and 50° north latitude. Year-round solar radiation conditions are better than many places in the world with similar average temperatures. Suitable temperature and good solar radiation make the yield of fruits and vegetables abundant and various in our country. The ensuing fruit and vegetable picking has become a difficult problem. At present, fruit and vegetable picking is mainly divided into two categories: manual picking and robotic arm picking. [0003] Due to the underdeveloped agricultural science and technology in our country, most of the farmland is scattered and the farmland a...
