Abstract

The invention discloses an impurity removing and air discharging machine for a cane harvester. The machine comprises a rotary bellow, a motor, impellers, a bellow shaft, a left air inlet box, a right air inlet box, a guide bin and an air outlet cover plate, wherein the motor is connected with the bellow shaft through a coupler, the bellow shaft is connected with the two impellers through keys, the two impellers are arranged in the rotary bellow, arc-shaped flanges are arranged on the inner walls of the left end face and right end face of the rotary bellow, the bellow shaft penetrates through center through holes of the arc-shaped flanges, bearings are arranged at the centers of the outer walls of the left end face and right end face of the rotary bellow, and the bellow shaft is connected with the bearings; the outer walls of the left end face and right end face of the rotary bellow are connected with the left air inlet box and the right air inlet box respectively, an air outlet of the rotary bellow is in butt joint with the guide bin, and the guide bin comprises a guide cavity and the air outlet cover plate; the lower end of the guide cavity is connected with the air outlet of the rotary below, and the guide cavity is divided into an upper air chamber and a side air chamber from the middle section of the body of the guide cavity; the upper end face of the guide cavity is connected with the air outlet cover plate, and a plurality of exhaust holes are formed in the air outlet cover plate.

Description

technical field [0001] The invention relates to the field of sugarcane harvesters, in particular to an impurity discharge fan of the sugarcane harvester. Background technique [0002] my country's sugarcane planting areas are concentrated in the south, mainly in Guangxi, Guangdong, Hainan, Fujian, Yunnan and other provinces. However, after joining the World Trade Organization, my country's sucrose industry is facing severe challenges from the international market. The world's largest sucrose producing countries such as Brazil and Australia have basically realized mechanization in production, and the production cost of sucrose material is about 70-80 yuan / ton, while The degree of mechanization of sugarcane production in my country is relatively low, and the production cost is about 110-150 yuan / ton, which is nearly double the advanced level in the world. The production cost of sucrose is too high, and the sugar price is not competitive in the international market. Therefore, ...
