A pineapple auxiliary picking mechanical arm

Abstract

A pineapple auxiliary picking mechanical arm, comprising a fixed shell, an arm support plate, a grasping structure, a power connection structure, and a radial fixed hook; the fixed shell is connected to the arm support plate, the grasping structure and the The power connection structure is installed in the fixed shell and the arm support plate, and the radial fixed hook is installed outside the fixed shell; the power connection structure includes several scissor linkages, outer fixed guide rails and inner slide plates. The grabbing structure includes a push plate and two grabbing claw heads. The middle parts and ends of the several scissor links are hinged to form an X-shaped scissor link structure, and one end is connected to one end of the inner slide plate through the spring. ; the other end is connected with the other end of the inner slide plate and the grabbing head, the inner slide plate is slidably installed in the outer fixed guide rail, the outer fixed guide rail is installed in the fixed shell, and the push plate It is installed on one end of the inner sliding plate and is located at the same end as the grabbing claw head.

Description

technical field [0001] The invention relates to the technical field of fruit picking instruments, in particular to an auxiliary pineapple picking mechanical arm. Background technique [0002] Due to the special structure of the pineapple tree and fruit, as well as the economic value of pineapple stems and buds, most of the pineapple picking in China is still purely manual. During the picking process, people need to bend over constantly, which is time-consuming and laborious, and the pineapple leaves are relatively hard. There are prickles on the pineapple fruit, which are very harmful to human hands. In response to the above problems, some simple fruit picking devices already exist in the prior art to assist pickers in fruit picking. Among them, the utility model application No. 201721427921.1 is "a fruit picking mechanical arm", which includes a control rod, a base, and a bracket. , the first rotating rod, the second rotating rod and the clamping part. The mechanical arm i...

[0002] Due to the special structure of the pineapple tree and fruit, as well as the economic value of pineapple stems and buds, most of the pineapple picking in China is still purely manual. During the picking process, people need to bend over constantly, which is time-consuming and laborious, and the pineapple leaves are relatively hard. There are thorns on the pineapple fruit, which is very harmful to human hands

In response to the above problems, some simple fruit picking devices already exist in the prior art to assist pickers in fruit picking. Among them, the utility model application No. 201721427921.1 is "a fruit picking mechanical arm", which includes a control rod, a base, and a bracket. , the first rotating rod, the second rotating rod and the clamping part. The mechanical arm is suitable for human operation and will not cause damage to the fruit tree, but this utility model is only suitable for fruits with fragile fruit handles that are easy to tear. For pineapples This kind of fruit stalk is thick, and it is not suitable for fruits that are not easy to pull to separate the fruit, and excessive pulling is easy to cause damage to pineapple stems and buds
