Auxiliary picking mechanical arm for pineapples

Abstract

The invention discloses an auxiliary picking mechanical arm for pineapples. The auxiliary picking mechanical arm for pineapples comprises a fixed housing, an arm support plate, a grabbing structure, apower connection structure and a radial fixed hook, wherein the fixed housing is connected with the arm support plate, the grabbing structure and the power connection structure are installed in the fixed housing and the arm support plate separately, and the radial fixed hook is installed outside the fixed housing; the power connection structure comprises a plurality of scissor-fork connection rods, an outer fixed guide rail and an inner slide plate, the grabbing structure comprises a push plate and two grabbing jaw heads, the middle parts and the end parts of the plurality of scissor-fork connection rods are hinged in pairs to form an X-shaped scissor-fork connection rod structure, and one end of the X-shaped scissor-fork connection rod structure is connected with one end of the inner slide plate through a spring; and the other end of the X-shaped scissor-fork connection rod structure is connected with the other end of the inner slide plate and the grabbing jaw heads, the inner slideplate is slidably installed in the outer fixed guide rail, the outer fixed guide rail is installed in the fixed housing, and the push plate is installed at one end of the inner slide plate and locatedat the same end as the grabbing jaw heads.

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...

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
