DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resistance device for a single-pass milling machine.

[0002]

2. Description of the Related Art A single pass milling machine is provided with a resistance device facing a white rice discharge port of a milling room. This resistance device adjusts the discharge pressure of the grain at the outlet of white rice, and is a very important device.

[0003]

The white rice bran of the heated white rice easily contacts and adheres around the resistance device at the white rice discharge port. In particular, in the winter season when the outside air temperature is low, dew condensation occurs from the resistance device portion to the white rice discharge port and the periphery of the discharge gutter, and bran sticking becomes severe. As a result, a malfunction of the resistance plate of the resistance device occurs, resulting in uneven polishing or poor operation. Therefore, the periphery of the resistance device must be cleaned before the bran sticks.

However, in order to perform this cleaning work, it is necessary to remove a large number of screws and disassemble or assemble a part of the complicated resistance device. In addition, during assembly, the centering of the resistance plate of the resistance device and the center axis of the white rice discharge port must be so-called centered so as to be in the same straight line, but this work takes time and it is difficult to perform accurate centering. It is.

[0005] Therefore, a front cover is detachably provided in a window hole on the front of the frame, and a resistance device is mounted on the front cover. At the same time, operating parts such as switches, breakers, and timers are provided on the front cover. The above problem has been solved (see Japanese Patent Publication No. Hei 2-21861).

However, in this rice milling machine, when electric parts such as a switch, a breaker, a timer, etc. are integrated, the electric parts always have a wiring relation on the back surface, and the electric resistance of the resistance device is determined due to the length of the lead wire. It is difficult to completely remove the assembly from the main body of the rice mill and carefully clean the periphery of the whitening room and the resistance device. In addition, it is not always easy, and it is almost impossible to remove the front cover from the rice milling machine body completely by removing the lead wires of the electrical components.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a resistance device which can be easily centered and can be easily attached and detached.

When the resistance handle 14 is turned in a predetermined direction, the resistance pin 17
The resistance pin 17 presses the resistance spring 22, so that the pressure force of the resistance disk 13 against the white rice discharge port 2 of the polishing room 1 is increased. For this reason, the resistance disc 13 increases the pressure on the white rice to be discharged by increasing the pressure applied to the white rice discharge port 2 and increases the whitening pressure.

When the resistance handle 14 is turned in the opposite direction, the resistance pin 17 slides in the opposite direction, and the pressing force of the resistance spring 22 of the resistance pin 17 is reduced.
The pressure force of the resistance disc 13 against the white rice discharge port 2 of the polishing room 1 is weakened. Therefore, the resistance disk 13 weakens the pressure applied to the white rice discharge port 2 to lower the pressure on the white rice to be discharged, so that the whitening pressure is reduced.

After setting the handle 14 on the predetermined scale 23, the motor M is driven to drive the suction fan K and the whitening roll SR, and the lever L is pulled to open the shutter S. The raw material G in the raw material tank T falls into the whitening chamber 1, advances in the whitening chamber 1 while receiving the resistance of the resistance device R, is whitened, and falls from the white rice outlet 2 into the discharge gutter 24. .

At this time, the resistance disk 13 is connected to the resistance spring 2
