Corn combine harvester

Abstract

The invention discloses a corn combine harvester. The harvester consists of a rack, a header, a gap bridge, a threshing device and a grading device. The header is connected to a threshing chamber through the gap bridge. The threshing chamber is fixed on the rack. The gap bridge is hinge jointed to the rack through a bearing block of a driving shaft. The threshing device consists of a threshing chamber, and a threshing cylinder installed in the threshing chamber. The threshing chamber consists of an upper cover and a concave grate. The grading device consists of a grading sieve. The header is a header for harvesting wheat. The gap bridge is a gap bridge for harvesting wheat. The concave grate is a grid concave grate. The grading sieve is a fish scale grading sieve. The corn combine harvester can efficiently reduce the purchase cost of corn harvesters, increase the usage frequency of corn combine harvesters, and reduce the production cost of users.

Description

technical field [0001] The invention relates to a grain harvesting device, in particular to a corn combine harvester. Background technique [0002] The currently used corn combine harvester is used for harvesting. Its structure is composed of walking part, power part, header, bridge crossing, threshing, clearing, grain lifting, high-level unloading and other components. It is mainly used to harvest mature corn. Wheat combine harvester, its structure is composed of walking part, power part, header, bridge crossing, threshing, clearing, grain lifting, high-level unloading and other components; it is mainly used to harvest crops with low water content after the grains are mature, such as Wheat, soybean and other varieties. Because corn has high stalks, large ears, large grains, and high water content, and wheat has low stalks, small ears, small grains, and low water content, when harvesting wheat with a corn combine harvester, it cannot meet the harvesting and threshing proces...

AI Technical Summary

Problems solved by technology

Because corn has high stalks, large ears, large grains, and high water content, and wheat has low stalks, small ears, small grains, and low water content, when harvesting wheat with a corn combine harvester, it cannot meet the harvesting and threshing process requirements of wheat. This has led to the fact that the corn combine harvester can only harvest corn and cannot harvest wheat; Except for the difference in structure, other parts are common, that is to say, the common part can be used to harvest wheat or corn

It is precisely because of the existence of these non-common parts that the wheat combine harvester and the corn combine harvester cannot be used universally, which wastes the common structural parts, increases the cost of the user, and reduces the frequency of use of the combine harvester.
