Technical Field

The invention relates to the field of agricultural machinery, in particular to a sugarcane collecting and unloading device of a segmental sugarcane harvester.

Background

China is a world large country for sugarcane production, and meanwhile, sugarcane is an important economic crop in the south of China and also a main raw material for sugar manufacturing industry in China, and planting areas of the sugarcane are mainly distributed in Guangxi province, Yunnan provinces, Guangdong provinces, Hainan provinces and the like. The most developed areas of the Guangxi, particularly the sucrose industry, have formed one of the mainstay industries of the Guangxi economy.

At present, most of sugar canes in China still stay in the original manual cutting harvesting mode, the demand of labor force is large, the operation intensity is high, and the harvesting efficiency is low. With the increase of the demand of sugar materials and the transfer of rural labor force, the production cost of the sugarcane is rapidly increased, so that the sugarcane harvesting adopts a mechanized harvesting mode to replace manual felling harvesting is a necessary trend. However, most of the sugarcane harvesting machines used in the sugarcane harvesting field are medium-large sized combine harvesters, when the sugarcane is harvested, the cut sugarcane sections are conveyed to a transfer transport vehicle through an elevator, the transfer transport vehicle is required to be equipped to walk side by side along with the harvester for harvesting, and the sugarcane harvester is only suitable for being used in a small part of relatively flat sugarcane lands with large plots, the natural environment conditions of sugarcane production in China are severe, most of the sugarcane lands are located on hilly slopes, small planting scale small slopes of the sugarcane lands are large, the slopes are large, and the sugarcane collection mode of the elevator and the transfer transport vehicle is difficult to implement on the sugarcane lands with the small plots.
