Research status of hard stem cutting device

Stem cutting is a key link in crop harvesting. Sugarcane, cassava and other crops stem thick, hard texture, difficult to cut, cutting device performance is the key factor affecting the quality and efficiency of harvester operation. In this paper, the research status of hard stem crop cutting equipment at home and abroad was introduced. The existing problems and research status of hard stem cutter were summarized from key parameters, cutting resistance and power consumption, cutter wear and other aspects. It is pointed out that there are some problems in the research of hard stem cutting device, such as too simple modeling of stem, insufficient research on cutting tool materials, separation of stem and cutting tool, and lack of structural innovation. At the same time, it is expected to strengthen the basic research, in-depth research on cutting theory, carry out bionic cutter research, strengthen the combination of agricultural machinery and agronomy and other related development trends, in order to provide reference for the research of hard stem crop harvesting mechanization in China.
