Description
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a bidirectional sugarcane cutting and paving machine.
Background
The sugarcane is a big sugarcane producing country in China, the annual output reaches more than 8000 ten thousand tons, the production technology level of the sugarcane serving as an important economic crop in China is still in a relatively laggard state, the most prominent expression is that the mechanization level is very low, and the production cost of the sugarcane is high due to the increase of labor cost in the harvest season of the sugarcane. At present, the mechanized harvesting modes of sugar canes at home and abroad can be divided into two types of combined harvesting and sectional harvesting, a large-scale combined harvester is advanced in technology, complete in function and high in working efficiency, and is suitable for large-scale farms which are flat in terrain, wide in area and standard in planting, the sugar canes in China are mainly planted in mountainous and hilly basin landforms such as Guangxi, and sugarcane farmers mainly plant the sugar canes in a single-family extensive mode, so that the flexible, convenient and low-price medium-sized and small-sized sectional type sugar cane harvesting machinery can better meet the requirements of actual national conditions in China.
The sugarcane cutting and spreading machine is a small sugarcane harvesting machine capable of cutting, falling and spreading sugarcane, and the power matched with the sugarcane cutting and spreading machine is a small tractor or a walking tractor, so that the sugarcane cutting and spreading machine can replace manual sugarcane cutting. Has the characteristics of small volume, simple structure, relatively low cost and the like. At present, the representative machine types of the domestic sugarcane cutting and spreading machine are mainly a 4GZ-9 type sugarcane cutting and spreading machine produced by NANNING WTINGA Osmanthus fragrans vehicle company, a 4GZ-1000 type sugarcane cutting and spreading machine produced by China agricultural mechanization scientific research institute, and the like. At present, the domestic sugarcane cutting and paving machine is operated in a mode of single-side paving and right-side paving. When the cutting and spreading machine finishes a cutting and spreading stroke every time, the starting point needs to be returned to cut and spread the next row of sugarcanes. So that the sugarcane is inverted to the same side, and the next cutting and paving stroke is avoided from rolling, therefore, the idle stroke of the existing sugarcane cutting and paving machine accounts for half of the total stroke, the working efficiency is low, and the continuous cutting and paving operation can not be realized. Therefore, the left-right bidirectional sugarcane cutting and paving machine designed by the invention can solve the problems and greatly improve the cutting and paving operation efficiency.
