Description

Handheld Orange Picker

technical field

The invention belongs to the technical field of mechanical equipment, and in particular relates to a hand-held orange picker.

Background technique

The recently published "China Agricultural Statistics (2016)" shows that in 2016, the national fruit planting area (excluding melons, strawberries and dried fruits, etc.) reached 194.723 million mu, with an output of 181.194 million tons. The oranges in the south are evenly divided, with a planting area of 38.412 million mu, ranking first, with a total output of 37.649 million tons, accounting for 20.8% of the country's total fruit output, and temporarily ranking second. It can be seen that the scale of oranges is large. At the same time, in 2016, the nine largest oranges The production areas are Guangxi, Hunan, Guangdong, Hubei, Sichuan, Fujian, Jiangxi, Chongqing, and Zhejiang, and the production areas of oranges are widely scattered.

There is a problem of low degree of mechanization in orange planting in my country. In foreign orange producing countries such as the United States, Italy and Israel, except for the grafting of orange seedlings and the harvesting of fresh oranges for sale, which are manual operations, the rest of the orange management work has been mechanized. In my country, the management of scattered orange orchards is almost entirely manual. Larger-scale orange bases use machinery for spraying medicine, etc. At the same time, heavy physical labor such as pruning and fertilization of oranges still relies on manual labor.

At present, domestic citrus picking is mainly done by hand, using traditional scissors, fruit baskets and other tools for picking. Therefore, many people have proposed solutions to this problem. In foreign countries, some orange production bases use large-scale agricultural machinery for picking, but require The orange base is relatively flat, and most of the orange trees are sprayed with abscisic acid a few days before picking, and then shake the tree. For the orange production bases in China where oranges are produced in mountains and hills, it is difficult to pick large-scale agricultural machinery. There are many problems, such as failure to pick oranges, accidental damage to oranges, etc. Small farm tools + labor have great advantages. On the one hand, it reduces the workload of pickers, and on the other hand, it can improve the quality of orange picking.
