Abstract

The invention provides a cross-flow threshing separation device and method and a combine harvester, including a cross-flow threshing drum, a cover plate, a ventilation base, a concave plate screen, several blower blades, a conveying device, a detection device and a controller; The two ends are respectively connected with the ventilation base; the concave plate sieve is installed under the cover plate; the ventilation base is located under the concave plate sieve, and the cross-flow threshing drum is located between the cover plate and the concave plate sieve; distributed in the direction; the conveying device is installed inside the ventilation base, and is located below the concave plate sieve; there are several microwave emitting devices on the cover; the detection device is used to detect the temperature and humidity in the threshing and separating device; The microwave emission device is added to realize the real-time heating of the rice during the threshing process. In addition, the blower blades are added to the threshing drum to make the airflow flow through the threshing separation device continuously, preventing it from being absorbed by the rice again, and improving the drying efficiency. efficiency.

Description

technical field [0001] The invention belongs to the technical field of combine harvester threshing and separation devices, and in particular relates to a through-flow threshing and separation device and method and a combine harvester. Background technique [0002] The threshing and separating device is an important component of the combine harvester. The quality of the grains obtained by the threshing and separating device is related to the working performance of the combine harvester. Because the newly harvested rice has a high moisture content and is prone to heat, it is easy to store it in the grain depot. The accumulation of heat and humidity can lead to mildew in rice. Therefore, it is very important to carry out quick drying process to paddy simultaneously in the process of threshing and separating paddy. [0003] In view of the above problems, the patent CN201711187122.6 invented a cross-flow hot air type combine harvester wet material conveying and feeding device, w...
