DUAL HORIZONTAL SIDE-BY-SIDE DIVERTING LOWIMPACT THRESHING SEPARATION DEVICE

Technical Field

The invention belongs to the field of harvester threshing and separating device, in particular, relates to a low oscillation threshing and separating device of double cross shunt cylinders.

Background of the Invention

Threshing and separating system is the core working part of combine harvester, which threshing performance directly decides the working performance of the whole machine. In the field of rice threshing, for example,the threshing structure of the longitudinal flow threshing device, the horizontal flow threshing device and tangentialflow combined threshing device have been evented in the domestic and overseas; patented CN201280048847.6 invented a threshing device with lengthened material threshing and separating, which greatly improves the threshing and shortens threshing time of the crops; patented CN201110298025.0 invented half-fed threshing and separating device, which only carries on threshing the head of rice ear .The stalk without feeding into threshing cylinder greatly reduces the threshing power consumption; patented CN201410136610.4 invented a double longitudinal axial flow roller negative pressure feeding shunt device, which threshing through double rollers increased threshing efficiency; patent 201510192840.7 invented a threshing device driven by electric motors, which is substituted for engines. The existing threshing device has basically met the national requirement on the rice and wheat harvest index, but the threshing system has some problems such as the high power dissipation, the heavy impact of threshing cylinder, the large vibration of threshing device and the high crushing rate after threshing, which severely restricts the development of combine harvester to high quality and high-end model. There are many types offoreign threshing device in high-end combine harvester, but the threshing device of combine harvester in China is quite different from the same type in foreign countries. (1) Models are mainly aiming at the harvest of drought crops. The structure and product of rice threshing device are less; (2) with the increase of high-yielding rice production in China (yield of y two gifted 900 isl5082 kg/hm²), the stalk is more and more robust, the stalk toughness is more and more large, compared with the foreign drought crops to the threshing device requirements higher;(3) in order to shorten the growth time of crops, the water content of the stalk was higher and the threshing separation was more difficult when the rice was harvested in advance. (4)therestriction ofthe existing engine technology,the engine with heavy horsepower which is suitable for combine harvester is less.The whole machine power configuration also becomes a big bottleneck of the harvester development.

There are three main types of threshing device including horizontalaxial flow, longitudinal axial flow, horizontal and longitudinal axial combinedflow. The device with longitudinal axial flow can improve threshing efficiency by adding the length of threshing cylinder, however, at the same time, the whole machine is very difficult to clean and the damage of grains is severe after threshing.While the axial flow multi cylinder threshing device is convenient for clearing, but the threshing efficiency is lower and the vibration in threshing process is larger. The existing traditional high efficiency threshing and separating device is designed mainly to increase the stalk threshing stroke (threshing time) to improve the efficiency and improve the threshing effect, but there are problems with large power dissipation, high crushing rate, large impact and vibration of threshing cylinder.
