Embodiment Construction

[0028] Such as Figure 1-5 Shown, a kind of threshing system for combine harvester of the present invention includes threshing mechanism, grain screening mechanism and secondary threshing mechanism;

[0029] The threshing mechanism includes a cuboid threshing machine shell 1, a semi-cylindrical left top cover 2, a semi-cylindrical right top cover 3, a cuboid feeding bin 4, a cylindrical left threshing drum 5, a cylindrical Right threshing drum 6 and cylindrical feeding drum 7;

[0030]In the thresher shell 1, an intermediate partition 10 is arranged along the length direction, and the intermediate partition 10 divides the thresher shell 1 into a left threshing bin and a right threshing bin; the feeding bin 4 is installed in the thresher shell 1, And be positioned at the front side of threshing machine shell 1, be used for docking with the conveying trough of harvester; The rear side of the threshing machine shell 1 is provided with the grass outlet 20 communicating with the ...

Abstract

The invention provides a threshing system for combine harvesters, comprising a threshing mechanism, a screening mechanism and a secondary threshing mechanism. The threshing mechanism is used for dual-vertical shaft threshing of straws conveyed by a conveying trough. The screening mechanism is used for screening threshed grain to obtain clean grain. The secondary threshing mechanism is capable of conveying incompletely screened straws into the threshing mechanism for secondary threshing, and threshing effect is further improved. The threshing system is high in throughput, allows complete threshing, is high in durability and has promising application prospect.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a threshing system for a combine harvester. Background technique [0002] At present, when the combine harvester is harvesting, due to the limited throughput of the threshing machine, once the harvesting speed is too fast, the threshing machine will be too large, the threshing effect will be poor, and the threshing will often be unclean, resulting in larger grains. loss; moreover, in the long-term high-intensity working environment, the frame-type threshing rod of the existing thresher is prone to deformation, which is inconvenient to maintain and affects the performance of the harvester; at the same time, the grain purity obtained is not high and often contains relatively high Large unthreshed and clean straw. Contents of the invention [0003] The technical problem to be solved by the invention is that the thresher throughput of the existing combine harvester is low, the frame stru...
