Abstract

The auxiliary threshing and cleaning device comprises a device body and a feeding pipeline, the feeding pipeline is arranged on one side of the top end of the device body, a conveying chamber is arranged below the feeding pipeline, and a lifting auger is movably connected into the conveying chamber; a first driving motor is fixedly connected to one side of the conveying chamber, the output end of the first driving motor is fixedly connected with a lifting auger through a coupler, and a threshing chamber is arranged on the other side of the conveying chamber. According to the auxiliary threshing and cleaning device of the rice harvester, the discharging barrel, the discharging plate, the rotating disc, the rotating rod and the hanging bracket are arranged, the output end of a third driving motor drives the rotating disc to rotate through rotation of the rotating rod, so that the falling direction of the discharging plate is adjusted, the hanging bracket can adjust the inclination angle of the discharging plate, the harvester can be parked conveniently, and the discharging plate can be rotated while discharging; the discharging effect is better, and the problems that discharged materials are prone to accumulation and bagging is not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of rice harvesting and threshing, in particular to an auxiliary threshing and cleaning device for a rice harvester. Background technique [0002] After the rice harvester has harvested the rice, it is crushed first, and then enters the threshing and cleaning device. After a series of processing such as threshing and screening, the threshing is completed. At present, the threshing and cleaning devices on the market do not hit and break the rice husk in place when threshing, and the threshing effect is average. After the initial threshing, there is a lot of dust and sand, which cannot be screened out separately. After the granulation, it needs to be cleaned again. On the other hand, the angle of the discharge cylinder is fixed, and the angle cannot be rotated and adjusted, and the discharge is easy to accumulate. For large rice harvesters, the parking angle needs to be considered when discharging grains, which...
