Problems solved by technology

The powerful rubbing rate of the two full-length bar rollers and the spiral threshing for a long time will destroy the outer shell of the millet and cause the broken rate to exceed the standard, and it is also not suitable for harvesting rice.
The third method, although full-grain stalks with strong rubbing force are also used for threshing, but the single cross-cutting flow method has a short time for threshing crops, and the stalks are relatively complete after threshing, and the broken ear rate i

Embodiment Construction

[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0028] Because millet is a small crop, compared with wheat, rice, and corn, the grain quality is small, and the thousand-grain weight is only 2.4-3.5g, and there is a main stem in the middle of the ear, on which there are first-level branches, and second-level branches are produced on the first-level branches. Branches and three-level branches, each level of branch is a small yard, there are many grains on it, some as many as two or three hundred grains, if the threshing device of the traditional full-feed combine harvester is slightly modified to threshing, it will cause Grain yards and stalks are not easy to separate, grains are not easy to clean, large damage, high loss rate of entrainment cleaning and other major defects.

Abstract

The invention relates to a threshing cylinder for millet harvest, belonging to the technical field of crop harvest. The threshing cylinder for the millet harvest comprises a close-type conical front cylinder and an open-type rear cylinder; the open-type rear cylinder comprises a cylinder shaft, a width plate and multiple threshing toothed bars, wherein the cylinder shaft is coaxially connected with the close-type conical front cylinder, the width plate is connected with two ends of the cylinder shaft, and the multiple toothed bars are uniformly arranged on the cylinder shaft in a circumferential direction and connected on the width plate; of the multiple threshing toothed bars, some threshing toothed bars are each provided with a rasp-bar toothed bar and multiple grass arranging teeth, and some threshing toothed bars are each provided with a combined toothed bar and multiple grass arranging teeth; and the combined toothed bars each are formed by mutually and alternately spacing and arranging multiple threshing teeth and multiple arc-shaped spring-teeth. According to the threshing cylinder for millet harvest, the threshing time is long, the separating area is large, and the sticking screens provided with rods and vanes with green stalks are reduced.
