Description

Semi-automatic fruit picking scissors

Technical Field

The invention relates to the technical field of fruit picking scissors, in particular to a semi-automatic fruit picking scissors.

Background

At present, the agricultural industry develops faster and faster, fruits are one of the most important industries, for fruit picking work, two main modes exist at the present stage, one is to use fruit picking scissors for manual picking, and the other is to use picking machines for mechanical picking, wherein the manual picking is convenient and fast, can be suitable for various terrains, but is only limited to fruit trees which are lower than two meters from the ground, and has high labor intensity and low picking efficiency, and for fruit trees which are higher than two meters from the ground, the fruit trees need to stand on a short ladder or a high stool, and the picked fruits are placed in fruit baskets or fruit baskets, so that the labor intensity is high, the picking efficiency is low, and a certain danger exists.

The picking machine is not suitable for mountain hilly areas because of large-sized machines, and often contains an autonomous mechanism with extremely high technical content, so that the picking machine is expensive and is not suitable for small orchards, and the picking machine cannot reach the orchards due to the topography of some orchards.

However, in order to facilitate the operation, the existing fruit picker basically uses scissors to cut fruit stalks or directly pull fruits from branches and tendrils, but due to the fact that the positions of some fruits are higher, workers standing on the ground cannot see the positions of the fruit stalks, and due to the shape and opening size of the scissors, a part of positions of openings of the collecting cavity can be blocked, so that some larger fruits cannot enter the collecting cavity and are difficult to pick, and the fruit picker is also characterized in that some fruit peels are thinner, if the fruits are hard to pull, the surfaces of the fruits are damaged, the selling of the fruits is affected, and some fruits are hard to get in a branch, so that the picking of one fruit is time-consuming and labor-consuming.

Therefore, in view of the above-described technical problems, a semi-automatic fruit picking scissors is needed.
