[Action]

 When performing the sorting work, the grains that have been threshed by the swing sorting board are swing-sorted, and the sorting wind is supplied from the Kara Minowa to blow away straw debris and dust to the rear for sorting.

At this time, the sorting air can be supplied through the oscillating sorting board side blast passage and the first conveyor side blasting passage, respectively, and further, the sorting wind can be fed through the oscillating sorting board side blast passage. It is possible to let the inside of the sorting air inlet open to the inside of the chaff sheave and the glensieve through the net body and to pass through the chaff sheave from the lower part to the upper part. The straw chips, etc. above the chaff sheave or the straw chips, etc. falling down from the chaff sheave can be blown backward to be selected by passing the chaff sheave upwards, and the chaff sheave is also clogged with the straw chips and the like. It is possible to prevent the above, and to ensure a good selection function for the same chaff sheave.

Similarly, dust scattered above the Glen sieve or dust falling downward from the Glen sieve can be blown back and selected, and dust can be prevented from clogging the Glen sieve. As a result, it is possible to ensure a good sorting function for the Glen Sieve.

Further, since the air flow direction plate is provided in the middle of the air flow passage on the side of the rocking sorting board, the air flow direction plate allows the amount of sorting air flowing below the chaff sheave and the grain sieve to flow depending on working conditions. It is possible to adjust the distribution amount of the sorting airflow flowing downward, and especially when morning dew adheres to the harvested rice, straw dust, dust, etc. also become moist and easily adhere to the chaff sieve. However, in this case, by increasing the sorting air flow to the chaff sheave side, the straw debris, etc. are surely blown back to prevent straw debris, etc. from adhering to the chaff sheave, and Good selection function can be secured.
