[Detailed description of the invention] (Industrial application field) The present invention relates to a rice polishing device.

(Prior Art) Conventionally, a device in which removable and replaceable strip-shaped rice milling roll pieces are attached to the front, rear, left, and right sides of the outer periphery of a mounting cylinder is known.

(Problems to be Solved by the Invention) In the above-mentioned known example, the rice milling roll pieces were provided on the front, back, left and right, so the area of the milling chamber was correspondingly narrowed, and therefore the absolute number of rice grains flowing in from above was insufficient. 1. It was not possible to rub it strongly.

(Means for Solving the Problem) Therefore, the present invention provides for attaching removable and replaceable strip-shaped rice milling roll pieces only to the front, rear, left and right sides of the outer periphery of the mounting cylinder, and attaching the rice milling roll pieces to both the left and right sides. As a rice milling device, a wide-area inlet chamber is formed on the outer circumferential surface of the rice milling trochanter, and a rubbing body is attached to the corner inner surface of the polygonal bran removal tube that surrounds the rice milling trochanter. The absolute number of rice milling rollers is increased to enable strong rubbing between the rice milling roll pieces and the rubbing body, thereby enabling efficient rice milling.

The pieces are combined to form one bran removal cylinder 13. 19 are four vertical pillars installed on the front, back, left, and right, and the inner surface of each pillar has a bran removing tube 13.
The rubbing body 20, which serves both to attach the rice grains and to rub the rice grains, is attached with an appropriate fastener 44.

Both left and right ends 21 of the rubbing body 20 protrude left and right beyond the vertical column 19, and the ends of the bran removing tube 13 are brought into contact with the ends 21 from the outside. Fit them from both sides and tighten them with screws 23 to fix them. Therefore, when the screw 23 is loosened, the presser 22 is removed and the bran removing cylinder 13 is removed.
can be replaced.

Inside the center of the dogleg-shaped bran removal tube 13 is the rubbing body 20.
A sliding member 24 of the same shape is brought into contact with the sliding member 24 and fixed from the outside with a stopper 25.

The rice milling trochanter 17 has a hollow pipe 26 at its center, and the hollow pipe 26 is connected to the rotating shaft 15 and has one ventilation port 27. A gap 2B is provided on the outer periphery of the hollow pipe 26, and a mounting cylinder 29 is provided outside the gap 28. The mounting cylinder 29 has vertical slits 3 in the front, back, left and right at predetermined intervals.
Set 0.

The vertical slits 30 are formed with or without a passage 31 communicating with the gap 28. Rice milling roll pieces 32 are brought into contact with the front and rear outer peripheral surfaces of the mounting cylinder 29, and arcuate pieces 33 are brought into contact with the left and right sides. , and is fixed by the roll presser 34. The inner side 35 of the roll presser foot 34 is formed into a shape that fits into the slit 30, and the outer side is expanded into a tipper shape to form the presser foot portion 3.
form 6. 37 is a set screw for attaching the roll presser 34 to the mounting cylinder 29. The outer circumferential surface 38 of the roll presser 34 and the outer circumferential surface 39 of the circular arc piece 33 are formed into circular arcs with the same radius, and the outer circumferential surface 40 of the rice milling roll piece 32 is much larger than the outer circumferential surface 38 and the outer circumferential surface 39. It stands out.

Among the roll pressers 34, the roll presser 34 on the rotation rising side with respect to the polished rice roll piece 32 does not have a blowhole 41, and only the roll presser 34 on the lower side has a receding angle.
form.

The rice milling trochanter 17 is as shown in FIG.

It may be formed in a two-tiered structure, upper and lower.

(effect) Next, we will discuss the effect.

When grains are supplied from the supply hopper 8, the grains are transferred to the supply cylinder 7.
It flows into the whitening chamber 42 through the interior of the whitening chamber 42. Therefore, when the rotary shaft 15 is rotated by the motor via the pulley 16, the rice polishing trochanter 17 rotates to the left in FIG. 3, and the rice polishing roll piece 3
When the rice grains 2 and 2 come to the position facing the rubbing body 20, they are closest to each other, and at that time, the grains are subjected to friction and rubbing action, and the rice is polished.
When the rice flows out to the downstream side of the milled roll piece 32, the rice bran is removed by the blast of air passing through the ventilation opening 27, the gap 28, the passage 31, and the blowing hole 41, and the loose cylinder is discharged to the outside of the machine through the bran removing hole 18.

However, since the rice milling roll pieces 32 are provided so as to protrude outward only at the front and rear two locations, and are not provided on the left and right sides, when the rice milling roll piece 17 rotates once, the front and rear
The rice is compressed and rubbed by the rice polishing roll piece 32 at the location. Since the outer parts of the arcuate pieces 33 on the left and right sides of the rice milling roll piece 32 that do not protrude are formed into a wide space, the rice grains falling from above can easily flow into the milling chamber 42. The number of rice grains to be removed increases in absolute terms, and since these grains are rubbed between the rice polishing roll piece 32 and the rubbing body 20 or 24, the rice can be polished efficiently.

If the rice milling roll pieces 32 are provided in four locations, front, rear, left, right, as in the conventional structure, the cross-sectional area of the milling chamber 42 is small.
The absolute number of rice grains flowing in from above is insufficient, and as a result, powerful milling is not possible and efficiency cannot be improved.

(Effect) As mentioned above, conventionally, there are
A device equipped with a strip-shaped rice milling roll piece that can be detached and replaced is known. In the above-mentioned known example, the rice milling roll pieces were provided on the front, back, left and right, so the area of the milling chamber was correspondingly narrowed, and therefore the absolute number of rice grains flowing in from above was insufficient, making it impossible to rub the rice grains forcefully. Ta.

However, in the present invention, the removable and replaceable strip-shaped rice milling roll piece 32 is attached only to both the front and rear, right and left sides of the outer circumferential surface of the mounting cylinder 29, so the rice milling trochanter 17 can be easily manufactured.

In addition, the rice polishing roll pieces 32 are not attached to both the left and right sides,
Since the inflow chamber 43 with a wide area is formed on the outer peripheral surface, the absolute number of rice grains flowing into the inflow chamber 43 from above will inevitably be large.
Since a large amount of rice grains are compressed, they can be rubbed more forcefully, and the rice can be polished more efficiently.

Further, since the rubbing body 20 is attached to the inner surface of the corner of the polygonal bran removal tube 13 surrounding the rice milling trochanter 17, the rubbing between the rice milling roll piece 32 and the rubbing body 20 can be made stronger.
