Especially, the collection of the buds with the important medicinal value is carried out manually. There are some disadvantages to manual collection operations: firstly, the manual collection efficiency is low, and the amount of buds collected by one person in 1 hour is 1-2 jin; secondly, manual collection needs to be carried out by fingers, and the waist is sore and the hands are easy to fatigue after the collection time is long.

Other large-scale mechanical type shake picking equipment, shake branch and make the fruit drop, carry out the collection of fruit simultaneously. The picking mode has great damage to the fruit trees and large fruit dropping amount, so the implementation is not strong. The other is a small picking device, which sucks or rolls the fruit into the picking device through negative pressure or poking teeth to separate the fruit from the branches. The negative pressure suction type picking mode has the advantages that the air suction pressure is low, the fruits cannot be successfully separated from the branches to finish picking, the air suction pressure is high, the fruit trees and the fruits are damaged, and meanwhile, the leaves and the branches are sucked to scratch the fruits. The tooth-pulling roll-in picking mode has the advantages that the fruit cannot be captured conveniently due to the fact that the capturing opening of the equipment cannot be adjusted, and branches and fruits are easily damaged due to the fact that the rolling-in force of the tooth-pulling roll-in picking mode cannot be adjusted.
