[Action]

(General Action) The lower passive pulley 14 is driven by the main motor 76.
When the rotary mill rotates, the friction-type fine grain roll 15 and the downward feed grain spiral 16 rotate, and the auxiliary motor 76 rotates the upper passive pulley 3
When 7 is rotated, the grinding type rice polishing roll 38 is rotated. Then, when the flow rate control valve 73 is opened, it is fed downward by the downward feed spiral blade 49 in the supply cylinder 46, flows into the grinding rice polishing chamber 44 from the inlet 45 by the pushing blade 50, and is ground by the grinding type rice polishing roll 38. After the rice is milled, it flows out from the annular outlet 85 in the upper part of the grinding and polishing chamber 44, and moves from the communication chamber 80 to the lower feeding and grain feeding chamber 79. In the lower feed grain feeding chamber 79, the grain is fed downward by the lower feed grain feeding spiral 16, is milled in the friction milling chamber 18, and the milled rice is taken out from the outlet 68.

However, in the present invention, a vertically long supply cylinder 46 is provided outside the inflow port 45, the lower end of the supply cylinder 46 is closed by a horizontal bottom wall 47, and the horizontal bottom wall 47 has the lower end of the vertical axis 48 as an axis. Disguise,
A lower feed spiral blade 49 is attached to the outer periphery of the vertical axis 48, the lower end of the lower feed spiral blade 49 is near the upper edge of the inflow port 45, and a pushing blade 50 is attached to the position facing the inflow port 45. In addition, since the vertical axis 48 has the lower end locked and the upper end is a free end, the lower feed spiral blade 49 can be smoothly moved.
Although the grain supplied to (1) is fed downward, it is not directly pushed in as it is, but is changed in direction and is pushed into the inflow port 45 by the pushing blade 50, so that it is smoothly fed. Also, at the end of the supply, residual rice is produced. At that time, by blowing air with the blower 86, the residual rice can be pushed into the inflow port 45 and cleaned.

[0019]

The above-mentioned known example has a structure in which an inlet is formed in the lower part of the upper feed chamber of the spiral, and a supply cylinder is attached to the outside of the inlet, and the supply cylinder is a horizontal cylinder. There is a problem in that. The structure is not to supply brown rice directly to the grinding rice polishing room to polish the rice, but to the upper feed grain feeding room of the spiral provided at the lower part of the grinding rice polishing room, so the upper feeding spiral and the grinding rice polishing roll are integrated together. Since it rotates, it is driven by a grinding rice polishing roll that requires a tremendous rotation speed, and even the upper feed spiral rotates at a tremendously high speed, and a smooth action cannot be expected. Further, since a horizontal feed cylinder is attached outside the inflow port, a horizontal axis is provided in the feed cylinder, and a lateral feed spiral blade is fixed to the outer circumference of the horizontal axis, the horizontal feed tube Genmai-gun, which is pushed out by the feed spiral blade, is supplied so as to hit the upper feed spiral exactly, so the supply is too true, and that part is too strong and not smooth. Further, since the above-mentioned known device has a horizontal supply cylinder attached to the outside of the inflow port, the device travels sideways and becomes large in size.

However, according to the present invention, the outer periphery of the grinding type milled rice roll 38 which rotates in the vertical axis is surrounded by the bran removing cylinder 43, and the milled rice is ground between the outer surface of the grinding type milled rice roll 38 and the inner surface of the bran removing cylinder 43. A chamber 44 is formed, an inflow port 45 is formed in the lower part of the grinding and polishing chamber 44, and an outflow port 85 is formed in the upper part.
5, a vertically long vertical supply cylinder 46 communicating with the inflow port 45 is attached to the outside of 5, and the lower end of the supply cylinder 46 is closed by a horizontal bottom wall 47. A vertical axis 48 axially mounted on the bottom wall 47 is provided, and a lower feed spiral blade piece 49 having a lower end substantially flush with the upper edge of the inflow port 45 is fixed to the outer circumference of the vertical axis 48, and Since the ascending-type rice milling device is equipped with the pushing blades 50 on the outer circumference of the vertical axis 48 facing the inflow port 45, the inflow port 45 of the grinding rice polishing chamber 44 is formed in one corner of the lower part of the bran removing cylinder 43 to perform grinding. The outlet 85 of the rice polishing chamber 44 is a rising type rice polishing chamber 44 formed in an annular shape all around the upper portion of the polishing rice polishing chamber 44, but a vertically long supply cylinder 46 is provided outside the inlet 45. The lower end of the supply cylinder 46 is closed by a horizontal bottom wall 47, and the lower end of the vertical axis 48 is attached to the horizontal bottom wall 47. Otherwise, mount the lower feed spiral wings 49 on the outer circumference of the vertical axis 48, the lower end of the lower feeding spiral wing 49,
Since the pushing blade 50 is attached near the upper edge of the inflow port 45 and facing the inflow port 45, brown rice is smoothly supplied. Also, the grain fed downward by the downward feed spiral wing piece 49 is not directly pushed in as it is,
Since the direction is changed and the force is pushed into the inflow port 45 by the pushing blade 50, the supply is smoothly performed. Also, at the end of the supply, residual rice is produced, but at that time, if the blower 86 blows air, the residual rice can be pushed into the inflow port 45 by the wind, and cleaning is also effective. Also, since the vertical axis 48 has its lower end locked and its upper end is a free end, the portion just under pressure facing the inflow port 45 is supported, and the upper end into which the grain flows is a free end without any obstacles. Target.
