Description

a fruit picker

technical field

The utility model relates to the technical field of agricultural machinery, in particular to a fruit picker.

Background technique

With the rapid entry of modern technology into the development of agricultural production and the extensive use of agricultural machinery, the amount of planting has increased year by year, the economic benefits of fruit farmers have also increased, and people's consumption capacity has also continued to increase. China is the world's largest apple producer and consumer, with apple planting area and output accounting for more than 40% of the world's total, occupying an important position in the world's apple industry. The apple consumption market is mainly fresh fruit and processed products, the proportion of fresh fruit is as high as 90%, and processed products only account for about 10%. In order to ensure the quality of apples, timely picking is the top priority of my country's apple industry. For fruit growers, the harvest of crop fruits is a job that farmers need to face every year. Most of the fruit picking is mainly manual picking, which requires a lot of manpower, material resources and time, which is time-consuming and labor-intensive, and increases costs. For some higher-level fruit picking, It is often achieved with the help of some climbing tools, and the picking efficiency is low and the risk is high. Therefore, the traditional method of picking fruits is far from meeting the needs of picking large quantities of fruits, which limits the large-scale development of the forestry and fruit industry and planting industry. Therefore, some picking devices also gradually appear, but most of the existing picking devices are mostly large-scale picking machines, and the machines that can carry out large-scale picking are too large and expensive, and are not suitable for picking in some hilly or remote areas of China . And in the picking process, the situation of falling and damaging the fruit is prone to occur, which is inconvenient to use. Many fruit pickers on the market are either too simple, causing unnecessary labor time, or too complicated for the fruit grower to operate. Through the investigation and analysis of the needs of fruit farmers for picking fruits, a flexible fruit picker with strong versatility is designed, which can be carried and operated by a single person. It can be used for picking a wide range of fruit types, with low fruit failure rate and high picking efficiency. , with low cost and high versatility.
