Technical Field

The utility model belongs to the technical field of agricultural machine, concretely relates to two-way sugarcane harvesting machine of small-size whole rod-type.

Background

China is a large country for producing and using sugar, and the planting area of the sugarcane is large. At present, sugarcane harvesting in China mainly relies on manual sugarcane cutting by labor force, the labor intensity is high, the harvesting cost is high, the breakage rate of the sugarcane is high, the secondary growth of the sugarcane is influenced to a great extent, and the yield of the sugarcane is reduced. As a lot of labor force goes out to deal with workers in rural areas and labor force for farmers is greatly reduced, a mechanized harvesting mode is urgently needed. In the face of the series of conditions, the realization of mechanized production becomes the necessary way for the sucrose industry in China to improve competitiveness and go out of low valleys. However, the sugarcane harvester in China has the following problems and is difficult to popularize up to now.

In the south, the sugarcane is mainly planted in hilly areas, most of the sugarcane is planted in sloping fields, the terrain is complex, the sugarcane field is small in land block dispersion, the slope is large, and the tractor-ploughing channel is not smooth. The planting mode is dispersed, the mode is various, the variety is different, and the large area is reaped in a unified way. When the machine is used, the work is difficult to be finished in hilly and mountain areas, the gravity center of the machine is high, and the rollover accident is easy to happen when the machine works in the areas with large gradients.

Secondly, the prior sugarcane combine harvester mainly adopts a cutting type. Most of sugar factories in China are built in a mode of manually harvesting whole stalks and putting the whole stalks into the factories, and the whole stalk sugar manufacturing process is basically solidified. Due to the limitation of production conditions, the production mode of the prior sugar refinery can not ensure that the cut sugarcane is squeezed along with the cut sugarcane, the cut sugarcane is easy to deteriorate and damage after being stored for a long time, the cut harvest has high impurity content and serious sugar loss, and the harvest mode is not accepted by the sugar refinery.

Thirdly, the existing main whole-rod type paving and cutting machine can only work in one direction, and the sugarcane can be discharged from one side only after being cut down. After harvesting, secondary collection, leaf peeling and bundling are carried out manually. After the machine finishes harvesting a row of sugarcane, the machine needs to turn around or harvest from the other direction, and the working efficiency is low.
