An electric pear picker

technical field

The utility model relates to an electric pearl pear picker, which belongs to the technical field of agricultural and forestry equipment.

Background technique

Pearl pear is the best among the many pear fruits in Yunnan. It is mainly produced in Chenggong County, Kunming City. Because the orchard is mainly a small-scale farming method of decentralized cultivation and household management, the production scale is small, and the garden is located in hilly and mountainous areas. As a result, the working environment of fruit growers is complicated, and large-scale mechanical pickers are difficult to apply in this planting form. Fruit growers need special, efficient, low-cost, and labor-saving picking techniques. Existing high-altitude fruit picking tools, some tools are cumbersome in practical methods, but cannot improve the expected effect of work efficiency, and even accidentally injure fruits; other picking tools are expensive to purchase and use, and cannot achieve the purpose of reducing harvesting costs. Beating with bamboo sticks and climbing humanoid ladders to pick fruits will not only cause the quality of fruits to decline, but also cause certain personal safety. In order to reduce the overall picking time of pearl pears and meet the actual needs of pearl pear growers, a picker that is easy to use, high in efficiency and strong in specificity is invented.
