An integrated threshing and separation device of drum and concave plate sieve

Abstract

The invention discloses a roller and concave grate integrated type threshing and separating device. The device comprises a threshing cylinder body, wherein the threshing cylinder body comprises a transmission shaft, a plurality of connecting supports are symmetrically arranged at the two ends of the transmission shaft, the two ends of each toothed plate are fixed to the corresponding connecting supports at the two ends of the transmission shaft respectively, a plurality of spike teeth are arranged on each toothed plate and point to the transmission shaft, and a sub-concave grate is arranged between every two adjacent toothed plates. By the adoption of the device, on one hand, threshing and separating area is increased, blocking pressure and energy consumption can be reduced and threshing and separating efficiency can be improved, and on the other hand, structure is simple, and assembly and disassembly are convenient.

Description

technical field [0001] The invention relates to the technical field of a grain combine harvester threshing and separating device, in particular to an integrated threshing and separating device of a drum and a concave screen. Background technique [0002] The threshing and separating device of the grain combine harvester is one of the most important parts of the whole machine. The function of the threshing and separating device is to remove and separate the crop grains from the crop plants. Its device structure and performance directly determine the grain combined harvesting. The threshing separation performance and production efficiency of the grain combine harvester. The separation and separation devices of the existing grain combine harvester are basically separated from the threshing drum and the concave plate sieve. During the threshing and separation process, the moisture content of the material varies greatly and the feeding amount is unstable. , often lead to overload...

[0002] The threshing and separating device of the grain combine harvester is one of the most important parts of the whole machine. The function of the threshing and separating device is to remove and separate the crop grains from the crop plants. Its device structure and performance directly determine the grain combined harvesting. The threshing separation performance and production efficiency of the grain combine harvester. The separation and separation devices of the existing grain combine harvester are basically separated from the threshing drum and the concave plate sieve. During the threshing and separation process, the moisture content of the material varies greatly and the feeding amount is unstable. , often lead to overload phenomenon, causing blockage of the threshing and separation device, reducing the performance of threshing and separation, and increasing the harvesting cost of the crops. At present, it mainly relies on increasing the number of drums or the length of the drum to avoid the above-mentioned problems in the threshing and separation process

The Chinese patent with the publication number CN102177791A discloses a combined threshing and separation device of a horizontal tangential flow drum and a vertical dual axial flow drum. Although this device can solve the phenomenon of overloading, this device also has a complex structure and high production costs. , the power consumption of the harvester itself is large, and the harvesting cost will increase when the feeding amount is small
