Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural machinery, and in particular to a fruit picker. Background Art
[0002] With the rapid entry of modern technology into agricultural production and development, the extensive use of agricultural machinery has led to an increase in planting volume year by year, and the economic benefits of fruit farmers have also increased accordingly, and people's consumption capacity has also continued to improve. 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, and it occupies an important position in the world's apple industry. The apple consumer market is mainly fresh fruit and processed products, with the proportion of fresh food as high as 90%, and processed products accounting for only about 10%. In order to ensure the quality of apples, timely picking is the top priority of my country's apple industry. For fruit farmers, the harvest of crop fruits is a task that farmers have 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 necessary to use some climbing tools to achieve it. The picking efficiency is low and the risk is high. Therefore, the traditional method of picking fruits is far from meeting the demand for large-scale fruit picking, which limits the scale development of forestry, fruit industry and planting industry. Therefore, some picking devices have gradually emerged, but most of the existing picking devices are large-scale picking machines. The machines that can pick in large quantities are too large and expensive, and are not suitable for picking in some hilly or remote areas in China. In addition, during the picking process, it is easy to drop and damage the fruit, which is inconvenient to use. Many fruit pickers on the market are either too simple, bringing unnecessary labor time, or too complicated and not suitable for fruit farmers to operate. Through the investigation and analysis of the needs of fruit farmers for picking fruits, a highly versatile retractable fruit picker is designed, which can be carried and operated by one person, can be used for picking a wide range of fruit types, has a low rate of bad fruit, high picking efficiency, and has low cost and high versatility.
