Auxiliary device and method for picking cherries with sawtooth knife and easy-to-adjust comb structure

Abstract

The invention discloses a serrated knife assisted cherry picking device with an easy-to-adjust comb structure and a picking method thereof. An existing fruit picking machine is not easy to move and ishigh in manufacture cost. The serrated knife assisted cherry picking device consists of a telescopic device, a collecting device and a serrated knife comb picking device, wherein a transmission gearcolumn is driven by a motor; springs are arranged between the transmission gear column and a second intermediate gear column as well as a first intermediate gear column and a support gear column, twonuts connected to a threaded rod are arranged between the first intermediate gear column and the second intermediate gear column, and a spring is arranged between the two nuts; nuts are arranged on the outer sides of the transmission gear column and the support gear column; adjusting gears are fixedly arranged at two ends of each gear column; two ends of a serrated knife are separately fixed withthe support gear column and the transmission gear column. When shearing, the adjusting gears rotating to the top are used to comb cherry roots and provide a pulling force to the cherry roots; when theserrated knife rotating to the top is close to a fixed blade on a shell, the cherry roots are cut off by combined action of the shearing force of the serrated knife and the pulling force of the adjusting gears. The serrated knife assisted cherry picking device is small in size and low in cost.

Description

technical field [0001] The invention belongs to the technical field of fruit picking equipment, and in particular relates to an automatic cherry picking device with a serrated knife with an easily adjustable comb structure and a picking method thereof. Background technique [0002] In the field of automatic fruit picking, although there are relatively perfect automatic picking machines at home and abroad, they are often large in size, heavy in weight and not easy to move. During the picking process, the cherry fruit is mainly obtained by shaking the tree, which is easy Inflicting damage on the trees and fruit does not bring much convenience to fruit farmers who have a large number of cherry trees. In addition, its high cost often makes it difficult to promote quickly. Therefore, it is of great significance to study a serrated knife cherry picking device with an easy-to-adjust comb structure. [0003] At present, there are not many examples in the field of fruit picking. Fo...
