TECHNICAL FIELD
[0001] The present application relates to the technical field of fruit picking scissors, in particular to a semi-automatic fruit picking scissors. BACKGROUND
[0002] At present, the agricultural industry is developing faster and faster, and fruit is one of the most important industries. For fruit picking work, there are currently two ways, one is to use a fruit picking scissors for manual picking, and the other is to use a picking machine for mechanical picking. Among them, manual picking is convenient and can adapt to various terrains, but is limited to fruit trees less than two meters from the ground, and has high labor intensity and low picking efficiency. For fruit trees more than two meters from the ground, it is necessary to stand on a short ladder or a high stool and put the picked fruit into a fruit basket or a fruit basket, which not only has high labor intensity and low picking efficiency, but also has certain danger.
[0003] Among them, mechanical picking has high efficiency, but due to the use of large machines, it is not suitable for mountainous areas, and the picking machine often contains self-action function and high-technology mechanism, making the picking machine expensive and not suitable for small orchards. Due to the terrain of some orchards, the picking machine cannot reach the orchard. In order to change this situation, there is an urgent need for a fruit picker between the two, which is easy to operate, low in price and high in efficiency.
[0004] However, the existing fruit picker is basically using scissors to cut the fruit stem or directly pull the fruit off the branch, in order to facilitate operation. However, due to the high position of some fruits, the ground staff cannot see the position of the fruit stem, and due to the shape and opening size of the scissors, the opening of the collecting cavity is partially blocked, so that some larger fruits cannot enter the collecting cavity and are difficult to pick. Some fruits have thin skins, and if they are pulled hard, the surface of the fruit will be damaged, affecting the sale of the fruit. In addition, some fruits have many fruits on one branch, which is time-consuming and laborious to pick one by one.
[0005] Therefore, in view of the above technical problems, a semi-automatic fruit picking scissors is needed. SUMMARY
