Description

[0002] Although sugarcane mechanical harvesting is the development direction, at present, due to various reasons, the proportion of sugarcane harvesting by manual labor is still large in China. The traditional sugarcane harvesting machinery is a combined type harvesting machinery, which is divided into sectioning type and whole stalk type according to the harvesting mode of sugarcane. The combined type harvesting machinery is not suitable for operation in small plots and plots with large slope due to its large size and heavy weight, and has great influence on plots with high root stubble requirements.

[0003] With the development of technology and the improvement of sugar making process, step-by-step sugarcane harvesting machinery is gradually popularized.
