Cross-flow threshing separation device and method as well as combine harvester

Abstract

The invention provides a cross-flow threshing separation device and a method as well as a combine harvester, wherein the device comprises a cross-flow threshing cylinder, a cover plate, a venting base, a concave plate screen, a plurality of air blowing blades, a conveying device, a detecting device and a controller; two ends of the cover plate are respectively connected with the venting base; theconcave plate screen is installed below the cover plate; the venting base is positioned below the concave screen plate, and the cross-flow threshing cylinder is positioned between the cover plate andthe concave plate screen; the air blowing blades are distributed along the circumferential direction of the cross-flow threshing cylinder; the conveying device is installed inside the venting base andpositioned below the concave plate screen; the cover plate is provided with a plurality of microwave transmitting devices; the detecting device is used for detecting temperature and humidity in the threshing separation device; by adding the microwave transmitting devices on the cover plate of the cylinder, real-time heating carried out on rice is simultaneously realized in the threshing process,in addition, the air blowing blades are added on the threshing cylinder, so that airflow flows through the interior of the threshing separation device continually to avoid being absorbed by rice again, and thus the drying efficiency is improved.

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...

Problems solved by technology

[0004] The above invention patents can realize the drying treatment of specific objects, but they cannot be applied to the threshing and separation process of the combine harvester. Long-term high temperature will easily lead to qualitative changes in the amylase in the rice.
