A sorting air passage for wind-selecting the sludge, and a rice husk separation chamber for separating wind and rice husks at the end side of the air passage, and the bottom of the rice husk separation chamber extends from the discharge side of the blower fan. It is configured to communicate with the discharge pipe and discharge the rice husk to an appropriate place outside the machine by the wind force of a blower fan.

(B) Conventional technology In the de-air selecting machine configured as described above,
Conventionally, for example, as disclosed in JP-A-60-222152, in order to prevent the phenomenon of clogging of the rice husk by adjusting the wind force in the rice husk discharge pipe for discharging the rice husk to a proper place outside the machine, The one having the technical configuration in which the rotation speed of the blower fan is controlled according to the increase / decrease in the transportation amount of the rice husk has been disclosed.

(C) Problems to be Solved by the Invention As described above, the conventional configuration has a blower fan that adjusts the wind force in the rice husk discharge pipe that discharges the rice husk to an appropriate place outside the machine to increase or decrease the amount of the rice husk transported. In the present invention, when the rice husks from the bottom of the rice husk separation chamber are discharged to a place away from the machine by the rice husk discharge pipe, the rice husk discharge pipe is controlled. The longer the length, the greater the difference between the wind force at the start or near the end of the de-air-selection action, which is close to idle operation, and the wind force at the time of actual operation, causing the grains to scatter from the rice husk discharge pipe, causing loss. To do.

Therefore, in order to eliminate these scattered particles and eliminate the loss,
The present invention has been devised for the purpose of providing a device having a simple structure that can be adjusted so that the above-mentioned wind force difference does not occur, and that stabilizes the wind force at all times.

(D) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention provides a removing portion, a sorting air passage for wind-selecting sludge, and a terminal end of the sorting air passage. The dehulling machine, which comprises a rice husk separation chamber and communicates the bottom of the rice husk separation chamber with a rice husk discharge pipe extending from the air blowing side of the blower fan to discharge the rice husks by the wind force of the blowing fan, An exhaust port through which the air blown from the end of the sorting air duct is discharged, the exhaust port is communicated with the suction side of the blower fan through an air intake pipe, and an air volume sensing member is provided at the exhaust port. In addition, an intake port having an outside air intake amount control valve is opened in the air intake pipe, and the air amount detecting member and the outside air intake amount adjusting valve are interlockingly connected, and the air amount detecting member and the outside air intake amount adjusting valve are relative to each other.

(E) Action With this structure, the paddy supplied to the desorption part is slid off, and the sludge is dropped into the sorting air passage to be wind-sorted, and the mixed rice and brown rice like brown rice The second one is taken out of the plane separately.

Then, the rice husk is blown into the rice husk separation chamber along with the wind in the sorting wind passage, and enters the rice husk separation chamber, where the wind reduces its speed and the rice husk is separated from the wind, and the separated wind of the rice husk becomes a swirling airflow from the exhaust port. After being sucked by the blower fan through the suction pipe and blown through the inside of the chaff discharge pipe from the discharge side, the chaff separated from the wind in the chaff separation chamber stagnant and descended into the chaff discharge pipe from its bottom. However, the air blown through the rice husk discharge pipe is discharged to a proper place outside the machine.

In this case, when the wind force inside the rice husk discharge pipe fluctuates strongly due to an increase or decrease in the amount of rice husk that falls from the bottom of the rice husk separation chamber into the rice husk discharge pipe, the wind sucked by the blower fan from the suction pipe is also accompanied by this. Fluctuating, the wind pressure of the swirling airflow to the air volume sensing member provided at the exhaust port changes, and the outside air intake volume control valve automatically adjusts the opening of the intake port in conjunction with the movement of the air volume sensing member due to this wind pressure variation. The wind power becomes regulated.

In this way, the de-winding action during actual operation is performed, but at the start or near the end of the de-winding action, there is a large difference from the wind force during the actual operation described above. At this time, the attitude of the outside air intake amount control valve with respect to the air amount sensing member is changed and adjusted to adjust the opening of the intake port to the larger side and the wind force to the weaker side.
