Next, the effect will be described.

When undried paddy rice is loaded into the loading hopper 12f of the #7 dismounter 12, it ascends through the lifting filZ and then is loaded [J
13 and into the humidity control tank 4 and the down-flow type grain drying chamber 5 through a two-part helical gutter 15 with an upper helical conveyor 14 installed therein. Then, when the burner 21 is ignited, the suction fan 20 is rotated, and hot air is supplied from the hot air supply chamber 7 into the flow F type grain drying chamber 5, some of the unhulled rice in the flow type grain drying chamber 5 is exposed to the hot air. dried. When the rotary valve 9 is rotated at a constant cycle, the dried unhulled rice is fed out little by little by the rotation of the rotary valve 9, is disposed of onto the V-shaped receiving trough IO, and is transported laterally by the spiral conveyor 11. The water flows into the end of the elevator 12, travels through the elevator 12, and is again piled up and returned to the humidity control tank 4. -L
The stacked unhulled rice gradually flows into the grain drying chamber 5, where it is dried for the second time, and then piled up again into the humidity control tank 4, where it is dried about 4 to 6 times. When iterating,
Normal humidity control drying ends.

However, when the humidity control drying is finished, the loose dust and unhulled rice are removed.
The inside of the upper helical gutter 15 is cleaned to remove dust and husks, but as described above, the ejection lever 39 is drilled into the L-shaped ejection lever member IJ2 member 37. When the fan 22 in the fan case 1 of the dust extractor 16 is rotated by the motor 18 with the hook groove a of the vertical groove 38 being ignored, the ejecting lever 39 is attached to the hook groove a. When the remaining paddy is removed, the discharge port 31 is closed by the residual paddy discharge shutter 33, and the opening 23 is closed.
is closed to the shaft attachment part 25, and the two-sided part opening 20 is opened,
Furthermore, the dust exhaust valve 29 closes the side part I co 28 and opens the dust exhaust port 2.
6 is open, the dust in the upper helical gutter 15 passes through the upper opening 20 and the dust 126 together with air, and is discharged to the outside from the dust exhaust duct 27. Next, the ejection lever 39
by hand, disengage from the hook groove a of the vertical groove 38, and lower the ejection lever 39 along the vertical groove 38,
When engaged with the hook groove, the discharge rope 43 slides on the surface of the guide pulley 46 and is pulled downward, so that the residual paddy discharge shutter 33 is moved by the tension of the spring 34 held by the tongue 36. The drain port 31 of the residual paddy discharge funnel 32 is opened. Also wire 41.4
2 is also pulled in the opposite direction, so the L-shaped rod 44 of the outside air introduction valve 24 that had closed the opening 23 is pulled from the front by the wire 41, and the outside air introduction box 19 is opened around the shaft attachment part 25. It rotates inward in the horizontal direction to close the upper opening 20. Then, since the L-shaped rod 45 at one end of the wire 42 is also pulled forward, the dust exhaust valve 29 rotates forward about the shaft attachment part 30, closes the dust exhaust port 26 of the dust exhaust duct 27, and closes the dust exhaust port 26 of the dust exhaust duct 27. The side opening 28 is opened. At this time, since the fan 22 in the fan case 17 of the dust extractor 16 is rotating, outside air flows in through the opening 23, is blown into the upper helical gutter 15 through the side opening 28, and is blown into the upper helical gutter 15 through the side opening 28. Blow off the residue accumulated in the gutter 15 and remove the residual paddy from the residual paddy discharge port 31 described above.
2, it falls and is ejected outside.

Conventionally, in order to remove peat, rice, and paddy accumulated in the upper helical gutter 15 and clean the R in the upper helical gutter 15, a person had to climb a ladder and roughly hold it by hand. It was extremely troublesome and inconvenient.
