ブラシの耐久性を向上することにある。By the way, as shown in FIG. 11, with respect to the leading brush 42, since the rice grains hit the side portions of the brush 42, the leading brush 42 is inclined to the side opposite to the rotating direction. Ready to go. However, in the conventional device, the front brush 42 is in a state in which the brush longitudinal direction is along the direction inclined with respect to the radial direction of the rotating body R on the side opposite to the rotation direction, and therefore the front brush 4
When the rice grain hits the side portion of No. 2, the leading brush 42 is further inclined to the side opposite to the rotation direction, and the contact angle α of the rice grain with respect to the brush tip portion (that is, the brush tip portion when viewed in the axial direction). The angle in the longitudinal direction of the brush with respect to the movement locus of is considerably smaller than 90 °. If the contact angle α of the rice grain with the tip of the brush is small, the elasticity of the brush cannot be sufficiently exerted when the bran is scraped off, and there is room for improvement. Further, at the tip end portion of the leading brush 42, the wear in the rotation direction side gradually progresses and wears obliquely (that is, the angle of the worn brush tip surface with respect to the brush longitudinal direction is considerably smaller than 90 °). Therefore, there is also a problem that the durability of the brush is short because the ability to scrape off the bran becomes faster. The present invention has been made in view of such actual circumstances, and an object thereof is to improve the scraping ability of the bran by making the elasticity of the brush sufficiently act when the bran is scraped off.
It is to improve the durability of the brush.

The contact angle of can be made larger than that of the prior art, that is, can be brought close to 90 °. Therefore, when the head brush scrapes off the bran, the elasticity of the brush can be sufficiently exerted, and the bran scraping ability can be improved. Further, since the tip end portion of the leading brush is worn at a right angle to the brush longitudinal direction (that is, the angle of the worn brush tip surface with respect to the brush longitudinal direction is about 90 °), the durability of the brush is improved. Can be improved.

れ易い。By the way, when the brush is partially provided in the circumferential direction when viewed in the axial direction, the rice grains are located at the end opposite to the rotation direction (hereinafter referred to as the rearmost brush). The brush at the rearmost portion tends to fall on the side opposite to the rotating direction, because the brush flows toward the outer peripheral portion of the rotating body.

Since it is installed along the direction of
Even when the rearmost brush scrapes off the bran, the elasticity of the brush can be sufficiently exerted, and the scraping ability of the bran can be further improved.
Further, the tip of the last brush also wears at a substantially right angle to the longitudinal direction of the brush, so that the durability of the brush can be further improved.

構成により得られる効果に加えて、ランニングコストを
低減することができるという効果を奏する。By the way, as the operation time of the rice polishing machine elapses, the brush gradually plastically deforms in a state inclining to the side opposite to the rotating direction, and the tip portion gradually moves in the longitudinal direction of the brush. As it is worn diagonally, the ability to scrape bran is reduced. According to the characteristic configuration of claim 4, since the brush existing portion provided with the brush is detachably provided in the state in which the brush can be reversed in the circumferential direction, when the scraping ability of the bran is deteriorated, the brush existing is present. By removing the part from the rotating body, reversing it in the circumferential direction, and then attaching it again to the rotating body, the scraping ability of the bran can be restored. Therefore, since the usable time of the brush can be extended, the running cost can be reduced in addition to the effect obtained by the characteristic configuration according to the third aspect.

ブラシは、前記前記回転方向とは反対側に倒れ易いの
で、腰折れ状態になり易い。By the way, since the rice grains hit the side portions of the brush with respect to the leading brush in the portion where the brush is present, the leading brush is tilted to the side opposite to the rotating direction (hereinafter sometimes referred to as waist bending state). It is easy to become. Further, since the brush at the rearmost portion is likely to fall on the side opposite to the rotation direction, it is likely to be in a waist-break state.

奏する。Therefore, according to the fifth aspect of the present invention, of the surfaces of the brush existing portion, both ends in the circumferential direction of the brush are protruded toward the brush tip side from the surface of the brush installation portion. It forms a protrusion. That is, the rice grain is guided to the tip end side of the brush by the protrusion on the front side in the rotation direction, and hits the tip end side portion of the brush with respect to the leading brush. Further, the rearward protrusion in the rotation direction suppresses the rearmost brush of the brush existing portion from falling to the side opposite to the rotation direction. Therefore, in addition to the effect obtained by the characteristic configuration according to claim 4,
It is possible to prevent the leading brush and the trailing brush of the brush existing portion from being bent into a waist.

The air pressure-fed from the air supply passage 30, the air reservoir 33, the vent hole 8a, the vent passage H, the vent hole 41a, the recess 44g, the hole 44e in this order, is ejected from the vent hole 44e, further Rice chamber 40, vent 13

At the same time, the rice bran separated from the rice grains and the brush 42 are worn away during the rice polishing in the rice polishing chamber 40, and the debris and the like separated from the rice are also discharged. It should be noted that although the brush 42 is worn away to generate a residue, the amount of the residue is extremely small, as can be seen from the fact that, for example, when the rice grain of 20 t is ground, the brush 42 only wears about 1 mm. The residue is discharged together with the bran by ventilation by the suction fan 29 and the pressure-feeding fan 31.

It is designed to prevent fogging. By adjusting the damper 32, the amount of air sucked by the suction fan 29 is adjusted to be larger than the amount of air sent by the pressure feeding fan 31, and the inside of the polishing chamber 40 is kept at a negative pressure. I am doing it. Since air is also sucked from the ventilation holes 15 and other gaps, it is possible to prevent the bran from being discharged to the outside. Specifically, the suction air volume of the suction fan 29 is 1.3 times the suction air volume of the pressure delivery fan 31.
It is about double.

Although not described in detail, if the bran separating device is used to further remove the bran, 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 separator.
