Accumulation preventing device for rice-wheat combine harvester with function of baling

Abstract

The invention provides an accumulation preventing device for a rice-wheat combine harvester with a function of baling. The accumulation preventing device comprises a driving shaft, a threshing cylinder straw outlet, a material passage, a straw shifting mechanism and a baling device. The material passage comprises a material passage bottom plate and two material passage side plates, a material passage inlet is connected with the threshing cylinder straw outlet, and a material passage outlet is connected with the baling device. The straw shifting mechanism is arranged in the upper portion of the material passage and comprises a crankshaft, a connecting rod, shifting forks and a rocker; one end of the crankshaft is connected with the driving shaft while the other end of the crankshaft is connected with one end of the connecting rod through a rotary pair; the other end of the connecting rod is connected with one end of the rocker through a rotary pair; the other end of the rocker is fixed onto a frame; the shifting forks are arranged on the connecting rod. The accumulation preventing device has the advantages that straws discharged from a threshing cylinder can be timely and smoothly conveyed into a compression mechanism, straw accumulation and blockage are avoided, and operational stability and reliability are guaranteed.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an anti-accumulation device of an integrated rice and wheat harvesting and bundling machine, which can be widely used in the high-performance harvesting of rice and wheat and the joint operation of straw compression bundling and forming. Background technique [0002] my country is very rich in biomass resources. The annual renewable crop straw resources exceed 640 million tons, of which 512 million tons can be used as energy. Most of the existing combines harvest rice and wheat stalks by crushing them and returning them to the field. Since the stalks are not easy to rot in the field, farmers often burn them, causing air pollution. Under this form, the central and local governments have formulated a series of subsidy policies to support the comprehensive utilization of straw recycling. At present, some places use tractor-type picking and bundling machines for bund...
