Abstract

The invention discloses a grain threshing machine and belongs to the field of agricultural machines. According to the grain threshing machine, a weight counting gate is arranged at the joint of a feed hopper and a threshing machine shell, and a weight counting controller is arranged on the weight counting gate. A threshing device comprises three parallel threshing rollers. Triangular spike teeth are evenly distributed on the circumferential surface of each threshing roller. A screening device comprises a vibrating screen and a grain sucking device, wherein the vibrating screen is arranged below the threshing rollers. The vibrating screen comprises a primary vibrating screen body arranged on the upper layer and provided with 30-40-mesh meshes and a secondary vibrating screen body arranged on the lower layer and provided with 55-60-mesh meshes. An impurity cabin is arranged below the secondary vibrating screen body. One end of the grain sucking device is communicated with the portion between the primary vibrating screen body and the secondary vibrating screen body, and a grain outlet is formed in the other end of the grain sucking device. The grain threshing machine is simple in structure and easy to achieve, and threshing efficiency can be effectively improved.

Description

Technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grain thresher. Background technique [0002] Threshing is one of the most important links in the crop harvesting process, which refers to the process of removing the grains of the harvested crop from the ears. In the process of threshing, at the same time, it is necessary to separate out other extrudates such as short stems, glumes, sundries and grains as much as possible. In order to provide threshing efficiency of crops, thresher came into being. There are many types of threshers for different crops. However, the current grain threshers on the market are either too large and costly, which is not conducive to small agricultural households for backup, or the degree of automation is not high, and the threshing efficiency is low. Summary of the invention [0003] The present invention aims to provide a grain thresher to solve the above-mentioned problems. [0004] In order to a...
