Abstract

PURPOSE:To surely perform grading and simultaneously improve recovering efficiency of grain with shaking grading rack by feeding grains to be repeating performance onto the shaking grading rack with being dispersed in second diffusing cylinder. CONSTITUTION:Grain culm fed into threshing room 1 is treated of threshing during transferring in the threshing room 1, then threshed grain and generated waste straw are fed onto shaking grading rack 2. The grain and waste straw are separated and graded with shaking and transferring in said shaking grading rack 2, then grain is winnowed during falling from the shaking grading rack, thus the winnowed grain is risen by grain-rising device, etc., and exhausted to outside. Material to be repeatedly performed composed of a part of graded grain, waste straw and grain attached of rachis-branch, etc., are fed into secondary reduction device 3 and repeatedly fed onto the shaking grading rack 2 by the secondary reducing device 3. In said feeding, the material to be repeatedly performed is uniformly diffused and fed onto the shaking grading rack 2 by second diffusing cylinder 4 installed at exhausting part of the secondary reducing device 3, then graded in the shaking grading rack 2 with shaking and transferring.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a second processing device for a threshing machine.

Conventional technology Conventionally, a swinging sorting shelf was provided to receive the threshed grains in a threshing room and sort them while moving them while swinging, and the second sorted grains were returned directly to the swinging sorting shelf. It was a second processing device equipped with a second reduction device for sorting.

Problems to be Solved by the Invention The husks supplied into the threshing chamber are threshed while being transported within the threshing chamber, and the threshed grains and M waste generated during the threshing process are separated from each other on the swing sorting rack. The grains are separated into grains and straw waste after being shaken and transferred on this shaking sorting shelf, and the grains are wind-selected while leaking from the shaking sorting shelf, and the wind-selected grains are Grain is fried in a grain frying device and discharged outside the machine, and some of the grains that have been sorted and secondary materials such as straw waste and grains with stems attached are supplied to the second reducing device. The waste is again supplied onto the swinging sorting rack by the reducing device, and is sorted while being moved swingingly on this swinging sorting shelf.

The second product supplied onto the swing sorting shelf in the second reducing device is often supplied in a biased manner onto the swinging sorting shelf on the discharge port side of the second reducing device. Reliable sorting may not be carried out during the oscillating transfer on the oscillating sorting shelf, resulting in poor sorting of grains.
