Grain unloading barrel for harvester and harvester

Abstract

The utility model provides a grain unloading leakage-proof device for a harvester. The grain unloading leakage-proof device comprises a grain unloading cylinder body and a grain baffle, wherein the grain unloading cylinder body is used for conveying grains; the grain baffle is rotatably arranged at the end, where the grain unloading opening is located, of the grain unloading barrel, and after grain unloading is completed, the grain baffle rebounds to shield the grain unloading opening of the grain unloading barrel to prevent grain leakage; the grain baffle comprises a springback fixing assembly, one end of the springback fixing assembly is connected with the grain unloading opening of the grain unloading cylinder, and after grain unloading is completed, the springback fixing assembly drives the grain baffle to springback. The grain baffle can automatically rebound, the problem of grain leakage in the grain unloading process is solved, and grain waste is reduced.
