Abstract

The invention relates to a pneumatic assisted type precise berry harvesting device and method. A main unit of the pneumatic assisted type precise berry harvesting device comprises a car frame, a cab,a picking device, a fruit collecting device, a power and transmission device and a machine vision system. The picking device is composed of a vertical brush type picking device and a pneumatic assisted picking device. The machine vision system is composed of an area array CCD and an upper computer processor to finish recognition of the positions and distribution density of berries; and according to the machine vision system, firstly, the relative positions of berry fruits and the fruit density of the berry fruits at corresponding positions are judged by the area array CCD, then the relative positions of two brushing rollers in a brushing system are moved according to the position and density information, and the airflow intensity of airflow nozzles in a corresponding position area is adjusted, and the berry harvesting is completed mainly by brushing and supplemented by pneumatic force. The pneumatic assisted type precise berry harvesting device and method can be applied to automated harvesting operations of blueberries and other berries with different densities and have a wide range of the application.

Description

technical field [0001] The invention relates to the field of berry harvesting, in particular to an air-assisted precise berry harvesting device and method. Background technique [0002] Berries such as blueberries are an important part of China's fruit tree industry, and its industrial scale and economic value rank among the top in my country's forest and fruit industry. The domestic berry picking process basically relies on manual labor, and picking machinery is still in the initial stage of research and development in my country. Among the tools used for picking berries, the comb-shaped artificial harvester is the most common. During the fruit harvesting process, it is necessary to manually remove debris such as branches, leaves and stones, and finally put the harvested berries into containers. [0003] The research on berry picking machinery in foreign countries started relatively early, and the technical level and automation degree are relatively high. The United State...
