Research status and prospect of mechanized harvesting device for walnut

Walnut is an important cash crop in China, its harvest is characterized by short harvesting time and complex harvest environment. With the rapid growth of walnut output in China in recent years, the existing harvest technology has gradually begun to limit the development of walnut industry, the problems of mechanized walnut harvest are gradually highlighted, and it is the general trend to improve the mechanized walnut harvest system. The existing mechanical harvesting devices of walnut at home and abroad can be divided into segmented and integrated harvesting devices. By summarizing the structure, characteristics and working principle of the mechanized harvesting device of walnut, it is pointed out that there are some problems in the mechanized harvesting device of walnut at this stage, such as insufficient automation level, low integration degree of the device, insufficient terrain adaptability and poor operation effect. Some suggestions are put forward for the future development of the mechanized harvesting device of walnut, and the direction and ideas are provided for the improvement and innovation of the mechanized harvesting device of walnut. In the future, the development of walnut harvesting machinery will be oriented to automation, intelligence, integration, with stronger adaptability and reliability, to meet the needs of the constantly developing walnut industry.
