Description
Technical Field
The invention relates to agricultural mechanical equipment, in particular to a sugarcane leaf separating device of a segmental sugarcane combine harvester.
Background
With the improvement of economic level and the increase of labor cost, people have more and more requirements on cane sugar and the quality of cane sugar, and the requirement of the market on cane sugar by manually cutting cane sugar cannot be met. To reduce the harvesting costs, sugar cane harvesters have gradually replaced manpower. Currently, there is a trend towards mechanized harvesting of sugar cane, with two main types of harvesting machines: a cutting type sugarcane combine harvester and a whole-stalk type sugarcane combine harvester.
The whole-rod type sugarcane combine harvester has higher requirements on harvesting conditions, and is difficult to finish the requirements on harvesting and impurity removal for the growing bent or lodging sugarcane. The cutting type sugarcane combine harvester has low requirements on sugarcane harvesting conditions, can complete the task of harvesting the sugarcane with poor growth vigor, has better impurity removal effect than the whole-rod sugarcane combine harvester, and is very suitable for the national conditions of China. However, most of the sugarcane harvested by the segmented sugarcane combine harvester cannot meet the requirements of sugar factories, and the main reasons are low efficiency and high impurity content, and impurities mainly comprise sugarcane leaves, perennial roots, soil, stones and the like, so that the yield and the quality of the sucrose are influenced. Therefore, the development of the sugarcane leaf separating device of the segmental sugarcane combine harvester with high working efficiency and low impurity content rate has important practical significance. At present, most of the existing sugarcane leaf separating devices of the segmenting type sugarcane combine harvesters at home and abroad adopt an axial flow fan to remove impurities, namely, during working, sugarcane materials are instantly thrown out from an outlet of a conveying channel and enter the lower part of the axial flow fan, and impurities such as sugarcane leaves are discharged by negative pressure generated by the fan. A large amount of research and optimal design are carried out on the sugarcane leaf separating device at home and abroad, however, the sugarcane which meets the requirements of a sugar refinery can not be harvested, and the main reason is that the sugarcane leaf separating time of the existing sugarcane leaf separating device is short, and some impurities far away from a fan fall into a collecting hopper without being separated. The invention prolongs the sugarcane leaf separation time, and disperses the sugarcane leaves in the conveying process to enable the sugarcane leaves to be close to the fan, so that larger leaves are discharged by the fan, and other smaller impurities can fall below the fan, thereby achieving the purposes of improving the impurity removal efficiency and reducing the impurity content.
