Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and particularly relates to a sugarcane laying harvester. Background Art

[0002] At present, most sugarcane laying harvesters at home and abroad are large-scale combined harvesters for cutting sugarcane. There are mainly the following two methods for this sugarcane harvesting method: One is a harvester including a top-cutting device for cutting the top leaves of sugarcane and a root-cutting device for cutting the roots of sugarcane at the ground. However, at present, this kind of harvester lacks control over the top-cutting height and root-cutting depth. When harvesting sugarcane that is too tall or too short, the results are not ideal. It is both possible to cause incomplete cutting and more likely to cause waste in harvesting, making such harvesters lack intelligence and incomplete harvesting, appearing very inflexible and easily causing sugarcane waste. For the small-area sugarcane planting in large areas of hilly and mountainous regions in China, large harvesters cannot meet the requirements for sugarcane harvesting in hilly and mountainous regions. Therefore, relevant research has also been carried out in China for sugarcane harvesting in hilly and mountainous regions. However, after use, it has also been found that the machines generally have problems such as inflexible operation and high impurity content. Therefore, it is necessary to design a more practical sugarcane laying harvester. Summary of the Invention
