Device and method for automatically picking pineapples

Abstract

The invention discloses a device and a method for automatically picking pineapples. The device comprises a horizontal guide mechanism, propelling and gesture correcting mechanisms, twisting off harvesting mechanisms and a picking platform mechanism for connecting the mechanisms; the horizontal guide mechanism is used for guiding pineapple fruits to the positions between the propelling and gesture correcting mechanisms and the twisting off harvesting mechanisms, which are symmetrically arranged on the picking platform mechanism, by guide flat plates; the propelling and gesture correcting mechanisms are used for applying a backward action force to the pineapples, propelling the pineapple fruits to the positions between two symmetrically arranged and pretensioned picking belts in each twisting off harvesting mechanism and correcting the gestures of the pineapples to be the vertical state; the twisting off harvesting mechanisms twist off the pineapples from stems by using the differential motion of the symmetrically arranged picking belts and then backwards convey the pineapple fruits which are twisted off. The device and method for automatically picking the pineapples can realize automation and high precision and can protect the completeness of the pineapple fruits without the need of subsequent machining, and the picking cost is reduced.

Description

technical field [0001] The invention relates to the research field of crop picking equipment, in particular to a device and method for automatically picking pineapples. Background technique [0002] Because pineapple leaves are sharp and hard, and the leaves are accompanied by sawtooth, farmers need to wear protective clothing and goggles when picking pineapples to prevent the pineapple leaves from cutting their bodies. During the picking process, the farmer needs to cut the pineapple from the plant with a knife and put it in the basket on the back. During the picking process, farmers have to carry heavy baskets and walk through the thorny pineapple field, which consumes a lot of physical strength. This manual picking of pineapples is inefficient, labor-intensive, and time-consuming. Harvesting costs account for about 40% of the pineapple growing process. With the advancement of my country's science and technology to promote agriculture, it is obvious that vigorously devel...

Xu Liming of China Agricultural University et al. "A Pineapple Picking Robotic Claw" (200920246396.2) and South China Agricultural University Xia Hongmei et al. The positioning, gripping, twisting, releasing and other actions of human picking are used to pick pineapple fruits. Although the picking accuracy of this invention is high, the picking efficiency is too low, and the positioning of the manipulator is high, and it takes a long time. Cannot effectively reduce equipment cost
