Corrugated tapered corn thresher

Abstract

The invention discloses a corrugated tapered corn thresher. The corrugated tapered corn thresher comprises a conveying mechanism, a threshing mechanism, a separation mechanism, a transmission mechanism and a rack, wherein the threshing mechanism comprises a tapered roller and a driving device for driving the tapered roller to rotate; the tapered roller is vertically arranged; a large-opening end of the tapered roller corresponds to a discharging end of a material distribution cabin and a small-opening end of the tapered roller corresponds to a core discharging cabin; a plurality of rows of corrugated threshing belts and dispersion teeth are distributed on the inner surface of the tapered roller in a staggered manner; the setting direction of each row of corrugated threshing belts and the setting direction of each row of dispersion teeth are parallel to the middle axis of the tapered roller; each corrugated threshing belt is of a solid structure formed by extending a sealed plane formed by surrounding a lower bottom edge, two side edges and circular arcs connected with the upper ends of the two side edges according to an S-shaped track; and each dispersion tooth is of a conical solid structure formed by surrounding a bottom end surface, a side curved surface and a spherical surface connected with the upper end of the side curved surface. With the adoption of the corrugated tapered corn thresher, mechanical loss in a corn threshing process can be reduced, the threshing rate is improved, and corncobs are not crushed.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a corrugated cone corn thresher. Background technique [0002] Corn is one of the main crops in our country and is an important economic crop. In addition, corn is also an important feed and industrial raw material, which plays a vital role in the development of my country's grain production and animal husbandry. In recent years, the yield of corn has gradually increased, and people have paid more and more attention to the steps of ear picking, peeling, and threshing in corn harvesting. Among them, corn threshing is the key link in the harvesting work. The corn harvesters that appear on the market currently only It has the functions of ear picking, peeling, straw crushing, etc. The corn threshing process needs to be completed by the thresher alone. [0003] At present, most of the corn threshers used in our country are designed using the striking principle. This kind of cor...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the corn threshers used in our country are designed using the striking principle. This kind of corn thresher has defects such as high grain breakage rate, unclean threshing, and high impurity content. The effect will cause large economic losses at the same time. The damage of corn kernels will also affect the short-term and long-term storage of corn. Low-damage threshing is especially important for seed corn. The germination rate of damaged corn seeds is low, prone to mold, Infested and easily broken, it is not conducive to the production of corn seeds and the development of agriculture
