Adaptive bending-twisting metamorphic fruit-picking device

Abstract

The present invention aims to overcome the defect of picking fruits by means of pulling force or shearing force in the prior art and provide an adaptive bending-twisting metamorphic fruit-picking device, which comprises cam mechanisms that provide clamping and bending-twisting movements, parallelogram-shaped transmission mechanisms that drive the cam mechanisms to move translationally, a supporting mechanism and a traction drive mechanism. According to the present invention, following the principle of manually picking fruits, a set of parallelogram-shaped mechanisms and cam mechanisms are designed skillfully by using the metamorphic principle, and the two sets of mechanisms can be switched adaptively only by means of single drive, thereby achieving adaptive adjustment to the sizes and shapes of fruits and locking of fruits. In addition, the needed pulling force and bending-twisting force are provided in the picking process. The adaptive bending-twisting metamorphic fruit-picking deviceis completely in conformity with the hand fruit-picking principle, and simple in operation, reliable in work and favorable in economical efficiency.

Description

technical field [0001] The invention relates to the technical field of fruit picking devices, in particular to an adaptive bending and torsion metamorphic fruit picking device. Background technique [0002] Fruit picking is one of the most laborious and time-consuming aspects of fruit production. Fruit picking is time-sensitive, labor-intensive, costly and inefficient. The quality of fruit picking directly affects the quality, storage and sales of fruits, and ultimately affects market prices and economic benefits. The environment for fruit picking is complex, and there are three main problems: first, the safety of the pickers, that is, the arms are easily scratched or scratched by branches when picking by hand, and they may be injured when working at high places; second, The problem of fruit tree damage, that is, the damage to the branches during the picking process, etc.; the third, the quality of fruit picking, that is, when the picking method is improper, it is easy to ...

Fruit picking is time-sensitive, labor-intensive, costly and inefficient

The quality of fruit picking directly affects the quality, storage and sales of fruits, and ultimately affects market prices and economic benefits

The fruit picking operation environment is complex, and there are three main problems: first, the safety of the pickers, that is, the arms are easily scratched or scratched by branches when picking by hand, and they may fall when working at high places; second, The problem of fruit tree damage, that is, the damage to the branches during the picking process, etc.; the third, the quality of fruit picking, that is, when the picking method is improper, it is easy to have the phenomenon of peeling off the stem and heart, and it is also easy to fall directly on the ground to cause internal and external injuries and affect the fruit. The appearance is not conducive to fresh-keeping storage and affects economic benefits

Manual picking can effectively solve the quality problem of fruit picking, but it cannot avoid the safety problem of pickers, and the efficiency is low

[0004] Some designers have begun to design auxiliary devices to assist pickers in fruit picking operations. Most of the existing auxiliary picking devices can be used by pickers standing on the ground to complete high-altitude fruit picking. Most of the picking devices only use pulling force to separate the fruit stem and branches, which not only has serious problems such as picking quality and damage to branches, but also is laborious and inefficient.

For example, the auxiliary picking device that uses a knife to cut the fruit handle will cause serious damage to the branches; the use of an auxiliary picking device that rotates the fruit to twist off the fruit handle will lead to fruit core pulling and affect the quality of the fruit; The connecting layer between the broken stalk and the fruit branch will cause certain damage to the fruit and the fruit branch, and even cause other fruits to fall naturally
