Problems solved by technology

[0002] At present, most of the corn threshing cutting-flow roller devices used in full-feed combine harvesters adopt the structure of spiked or corrugated rod rollers and concave plates. The threshing effect of the threshing device with this structure is poor, resulting in serious crushing of corn kernels and large loss of kernels. , it is easy to block the cut-flow drum and affect the threshing speed

Embodiment Construction

[0010] like figure 1 A threshing and separation mechanism of a corn harvester is shown, including a gland 1 , a main shaft 2 , a bearing 3 , a bearing seat 4 , a feeding port 5 , an inner drum 6 , an outer drum 7 , a fixed frame 8 and a flywheel 9 . The main shaft 2 is fixed on the fixed frame 8 through the bearing 3, the bearing seat 4 of the fixed bearing, and the pressure cover 1. The inner drum 6 is installed in the middle of the main shaft 1, and the outer drum 7 is installed on the fixing frame 8 outside the inner drum 6. On the fixing frame 8 A feed port 5 is opened to lead between the inner and outer drums, the lower end of the main shaft 2 is equipped with a flywheel 9; the outer wall of the inner drum is equipped with rotating blades; the inner wall of the outer drum 7 is equipped with a small convex head.

[0011] When the mechanism is working, the mixture of small strips, small pieces and broken pieces of corn cobs after being drilled enters between the inner and o...

Abstract

The invention provides a threshing and separating mechanism of a corn harvester. The threshing and separating mechanism comprises a gland, a spindle, a bearing, a bearing seat, a feed inlet, an inner drum, an outer drum, a holder and a flywheel. The spindle is fixed on the holder through the bearing, the bearing seat for fixing the bearing and the gland, the inner drum is mounted on the middle portion of the spindle, the outer drum is mounted on the holder on the outer side of the inner drum, the inner drum and the outer drum are communicated via the feed inlet formed in the holder, and the flywheel is mounted at the lower end of the spindle. Besides, rotating blades are mounted on the outer wall of the inner drum, and small projections are mounted on the inner wall of the outer drum. Strips, blocks and chip mixtures generated after the corns are perforated are rubbed by the small projections on the inner wall of the outer drum under driving of the rotating blades, so that corn kernels are separated completely. The threshing and separating mechanism has high separation efficiency without damages to corn kernels.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a threshing and separating mechanism for a corn harvester. Background technique [0002] At present, most of the corn threshing and cutting flow drum devices used in the full-feed combine harvester adopt the structure of spiked teeth or ribbed drum and concave plate. The threshing device of this structure has poor threshing effect, resulting in serious corn grain breakage and large grain loss. , It is easy to block the tangential flow drum and affect the threshing speed. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a corn harvester threshing and separation mechanism, and the corn cobs are drilled and the mixture of small strips, small pieces and shreds pass through the mechanism to realize the separation of corn kernels. [0004] The technical scheme adopted in the present invention is: a threshing and separating m...
