Chopping-type sugarcane combined harvester with middle fans

Abstract

The invention relates to a chopping-type sugarcane combined harvester with middle fans. The chopping-type sugarcane combined harvester comprises a travelling device, a rack, a spiral line separator, apushover roller, a cutting table, a primary conveying channel, a secondary screen type conveying channel, a sugarcane receiving hopper, a driving cab and a power system and also comprises a middle air separation and impurity removal fan; the rack is mounted on the travelling device; the spiral line separator, the pushover roller, the cutting table, the primary conveying channel, the secondary screen type conveying channel and the sugarcane receiving hopper are sequentially arranged from front to rear on the rack in a material conveying direction; the driving cab and the power system are mounted on the rack; the middle air separation and impurity removal fan is located above a joint of the primary conveying channel and the secondary screen type conveying channel and is used for forwards moving the gravity center of the harvester and reducing the gravity center height of the whole machine; and a secondary air separation and impurity removal fan is arranged at the tail end of the secondary screen type conveying channel and above the sugarcane receiving hopper. The chopping-type sugarcane combined harvester adopts the double air separation and impurity removal fans including the middle air separation and impurity removal fan and the secondary air separation and impurity removal fan, so that the impurity removal efficiency and quality in a sugarcane harvesting operation process arefurther increased, and the impurity content of chopped sugarcanes is reduced; and the chopping-type sugarcane combined harvester belongs to the technical field of agricultural machines.

Description

technical field [0001] The invention relates to agricultural machinery technology, in particular to a section-cutting type sugarcane combine harvester with a fan installed in the middle. Background technique [0002] my country is a big sugarcane planting country. The main producing areas of sugarcane are Guangxi, Guangdong, Hainan, Fujian, Yunnan and other provinces. The concentration of sugarcane planting in these areas is high, and the large-scale planting of sugarcane has created good conditions for the mechanization of sugarcane production and harvesting. But the domestic sugarcane harvester is still the weakest link in the mechanization of sugarcane production. [0003] With the in-depth promotion of domestic agricultural mechanization, the technology of sugarcane harvesters is becoming more and more mature. At present, the sugarcane mechanized harvesting technology is concentrated on the whole stalk type and the segmented type. The segmented type has become the main m...
