Millet threshing device

Abstract

The invention provides a millet threshing device aiming at the problem that in the prior art, a grain threshing device is short in threshing distance, and consequently threshing is not thorough. The millet threshing device comprises a shell, a driving shaft rotationally arranged on the opposite side faces of the shell, a conical front end assembly arranged on the driving shaft and used for pushing grain ears, a rotary threshing assembly connected with the large diameter end of the conical front end assembly, driven by the driving shaft and used for threshing, and a shake separating assembly driven by the driving shaft and used for separating millet grains from impurities. The rotary threshing assembly and a grid concave plate I cooperate for threshing, the rotary threshing assembly is composed of a plurality of threshing rolls which are evenly distributed on the outer side of the driving shaft and are parallel to the axis of the driving shaft, and the threshing rolls all can rotate around the axes of themselves. The millet threshing device is simple in structure, the threshing rolls rotate around own axes, the rubbing distance can be increased, and the threshing efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a millet threshing device. Background technique [0002] Millet is a miscellaneous grain crop. Compared with wheat and rice, it is a small-grain crop. The weight of a single grain is light. There is a main stem in the middle of the ear, and there are multiple branches on the main stem. Contains two to three hundred grains. At present, my country's millet harvest mainly adopts two methods. One is that most areas are still manually harvested, and threshers are used for on-field threshing; the other is that a small number of areas are harvested by windrowers, and then the ears are picked and threshed after drying or directly threshed by threshers. In recent years, some enterprises or farmers have adopted grain combine harvesters such as wheat or rice, which have been slightly refitted and adjusted. [0003] Row millet harvest. But these machines are for corn ear, because th...
