DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating brush in which the roots of a plurality of brushes are bundled by a bundling means to form a brush bundle, and a plurality of the brush bundles are rotatably arranged in a bran removing cylinder. The present invention relates to a rice polishing apparatus attached to an outer peripheral portion of a body so as to come into contact with the surface of rice grains transferred in the rice bran cylinder.

[0002]

2. Description of the Related Art In such a rice polishing apparatus, as a configuration for attaching a brush bundle to an outer peripheral portion of a rotating body, conventionally,
A concave portion is formed in the outer peripheral portion of the rotating body R for inserting the bundled portion of the brush bundle bundled by the bundler from the front side, and the bundled portion of the brush bundle is inserted into the concave portion and fixed with an adhesive. Had to be configured.

[0003]

However, when the brush bundle is attached to the outer peripheral portion of the rotating body, the state of spread of the adhesive between the concave portion and the bundled portion, and the manufacturing variation in the amount of the adhesive and the like are caused. Among the plurality of brush bundles attached to the outer peripheral portion of the rotating body, the bundled portion may come off from the concave portion and the brush bundle may fall off from the outer peripheral portion of the rotating body, which has been improved. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a rice polishing apparatus that can prevent a brush bundle from falling off an outer peripheral portion of a rotating body.

[0004]

According to the first aspect of the present invention, the bundling portion of the brush bundle is moved from the brush tip side to the insertion hole of the brush base portion from the back side of the brush base portion. The brush base portion is attached to the rotating body by attaching means in a state where the brush base portion is inserted and is prevented from coming off to the surface side by the retaining portion. Therefore, the bundling portion can be reliably prevented from falling off to the front side by the retaining portion, so that the brush bundle can be prevented from falling off from the outer peripheral portion of the rotating body.

[0005] According to the characteristic configuration of the second aspect, the small hole portion of the insertion hole can reliably prevent the bundled portion from coming off to the surface side. Therefore, instead of separately providing a retaining portion, only by providing a small hole portion when forming the insertion hole, the retaining portion can be easily provided at the same time as forming the insertion hole. The invention can be implemented at low cost.

[0006] By the way, the higher the density of the brush attached to the outer peripheral portion of the rotating body, the higher the bran removal ability. When the brush bundle is formed into a flat shape in which one of the two brush arrangement directions orthogonal to each other is longer than the other, the number of attached brush bundles is reduced as much as possible.
Since the density of the brush can be increased, it is advantageous in terms of improving the bran removal ability and productivity.

According to the third aspect of the present invention, in the slit-shaped insertion hole, the portion where the slit width is smaller than the thickness of the bundle portion of the flat brush bundle prevents the bundle portion from coming out to the surface side. It can be reliably prevented. Therefore, even when a flat-shaped brush bundle that can increase the density of the brush is employed, when forming the slit-shaped insertion hole, only a portion having a slit width smaller than the thickness of the bundle portion is provided. Since the retaining portion can be easily provided at the same time as the insertion hole is formed, the present invention can be implemented at low cost.

[0008] In such a rice polishing apparatus, usually, in order to discharge the bran shaved from rice grains to the outside of the bran removing cylinder, an air hole for allowing gas to flow is opened in the surface of the brush base portion. .

According to a fourth aspect of the present invention, a plurality of flat-shaped brush bundles are rotated on the brush base in a state in which the longitudinal direction of each flat shape is aligned with the axis of the rotating body. Ventilation holes, which are juxtaposed along the circumferential direction of the body and allow gas to flow therethrough, are opened on the surface of the brush base portion, between the circumferentially adjacent brush bundles. Therefore,
Without splitting the brush bundle to form ventilation holes,
The individual brush bundles can be attached to the rotating body over substantially the entire length in the axial direction.

Therefore, not only can the density of the brush be increased, but also the brush can be brought into contact with rice grains over substantially the entire length of the rotating body in the axial direction by rotating the rotating body. In addition, the ability to scrape bran can be further improved. Moreover, the number of brush bundles to be attached can be further reduced, so that the productivity can be further improved.

According to the characteristic configuration of the present invention, an adhesive is interposed between the back surface of the brush base portion and the back surface of the base mounting portion of the rotating body. The brush base portion is attached to the base attachment portion by applying it in a state where the brush is applied. Therefore, since the structure of the attaching means is simplified, the present invention can be implemented at a lower cost.

According to the characteristic configuration of the present invention, the brush mounting portion is attached to the base mounting portion and the brush mounting portion is integrated with the base mounting portion separated from the rotating body, and the brush mounting portion is mounted as described above. Attach the base mounting part to the rotating body. When attaching the brush base part to the base attachment part, it is necessary to adjust the direction of the brush longitudinal direction with respect to the rotating body to a predetermined direction, and to adjust the position of the brush bundle with respect to the rotating body to a predetermined position. Required. Therefore, the operation of attaching the brush base portion to the base attachment portion can be performed easily, although high attachment accuracy is required, since the base attachment portion can be detached from the rotating body. Therefore, the productivity can be further improved.

At the same time, in the polishing room 40, the bran separated from the rice grains and the brush 42 are worn away due to the polishing, and the separated residue is also discharged. It should be noted that the brush 42 wears and generates residues, but the amount thereof is extremely small, as can be seen from the fact that, for example, when grinding 20 t of rice grains, the brush 42 wears only about 1 mm. The residue is discharged together with the bran by the ventilation of the suction fan 29 and the pressure feeding fan 31.

Further, by the suction action of the suction fan 29, air is sucked in from the outside through the vent hole 15, and is allowed to flow along the inner surface of the cylindrical portion 4a, so that the transparent portion of the cylindrical portion 4a is made of bran or the like. It is configured to prevent fogging. By adjusting the damper 32, the air volume sucked by the suction fan 29 is adjusted to be larger than the air volume blown by the pressure feeding fan 31, so that the inside of the polishing rice chamber 40 is maintained at a negative pressure. I have. Since air is sucked in from the ventilation holes 15 and other gaps, it is possible to prevent the bran from being released to the outside. Specifically, the amount of air suctioned by the suction fan 29 is set to 1.3 times the amount of air blown by the pressure feeding fan 31.
It is about double.

When rice is polished with the above-described rice polishing apparatus, almost all of the bran is discharged by the ventilation of the suction fan 29 and the pressure-feeding fan 31, and almost no bran remains in the rice grains. Although not described in detail, the detailed description is omitted, but if the bran is further removed by the bran separation device, the commercial value can be further improved. Even if the residue of the brush 42 remains, it is removed together with the bran by the bran separation device.
