Abstract: The orchard twig shredder is an important tool for orchard twig treatment and efficient resource utilization. It has certain ecological benefits for environmental protection. The control system is the key core component of the twig shredder, and its performance directly affects the performance and effect of the whole machine. The research status of the control system of the orchard shoot shredder at home and abroad is expounded from three aspects: the feeding control system, the crushing control system and the collecting box control system. It is analyzed that the current control system of orchard shoot shredder in my country has the problems of simple control system, poor stability, relatively single function and lack of innovation. It points out the development trend of improving control technology, improving automation and intelligence level, supporting each other with multiple systems, and reducing the production of ecological environment pollution and so on. It provides a reference for the study of the control system of the orchard shoot shredder.
