The guided rice is shelled by collision, and the rice supply unit has the rotation axis of the impeller portion A guide surface is provided on the outer peripheral portion of the rice supply portion, and the rice fed from one side in the rotation axis direction is guided to the other side, and the guide surface extends from the one side to the front side. In the other side, the impeller portion includes a plurality of blade bodies that extend radially from the radially inner side toward the radially outer side, and a dispersion guide that moves the rice discharged from the rice supply unit along the aforementioned The rotation axis direction is dispersed and guided to a space between the blade bodies adjacent to each other, and the dispersion guide portion includes a plurality of rice passage portions juxtaposed in the rotation axis direction, and the rice passage portion is along the rotation axis The core direction has a lateral width that allows one or more rice grains to pass radially outward, and is disposed in a state of being distributed over the entire circumference.

According to the present invention, the rice is carried in from the one side of the rotation axis direction with respect to the rice supply unit, and the carried rice is moved to the rotation axis by the guide surface provided from one side of the rotation axis direction to the other side. The other side of the direction is guided. Further, the rice that has been carried in is discharged radially outward. In other words, in the rice supply unit, even when the rice is transported from one side in the direction of the rotation axis, the rice is uniformly distributed from one side to the other side, and the distribution unevenness is small. Discharged toward the impeller section.

A dispersion guide is provided in the impeller portion to disperse the rice discharged from the rice supply unit in the direction of the rotation axis. The dispersion guide portion includes a plurality of rice passage portions that are aligned in the direction of the rotation axis. Since the rice passage portion is along the direction of the rotation axis, it can only supply one or more grains of rice radially outward.

Further, since the radially outer end portion of the rice supply portion is close to the radially inner end portion of the above-described partition forming body, once it is spread over After the rice passage portion is dispersed in the direction of the rotation axis, it is not moved from the rice supply portion and the partition formation body to the other rice passage portion, but is directly held by the rice passage portion.

Since a gap for introducing rice is formed between the rice supply unit and the sliding guide body, the rice which is dispersed in the direction of the rotation axis and guided to each of the rice passage portions can pass through the gap for introducing the rice inside the rice passage portion. And move freely in the week. As a result, the rice grains are dispersed in the circumferential direction, and are sequentially guided radially outward by the plurality of sliding guide bodies.

By sequentially guiding the plurality of sliding guides while maintaining the state in which the rice is dispersed in the direction of the rotation axis, it is possible to guide the rice husking operation efficiently without being guided to the blade body in the rice passage portion.

In the present invention, the rice supply unit is provided with a cylindrical rice guide body, and a rice inlet is formed on one end side of the rice guide body in the rotation axis direction, and is formed in the circumferential direction of the rice guide body.

The rice guide body 11 has a rice inlet 12 formed on one end side in the rotation axis direction, and the other end side in the rotation axis direction is closed by the side wall portion 10. The side wall portion 10 also serves as a bearing portion that rotatably supports a drive shaft 41 to be described later. A rice discharge portion 13 is formed by opening a part of the circumferential direction of the rice guide body 11. The rice discharge portion 13 is elongated in the direction of the rotation axis and opens so as to extend over the circumferential direction by about 90 degrees (see FIG. 8).

As shown in FIG. 9, the rice guide body 11 is connected in communication with the downflow guide portion 3 so that the rice M guided downward from the hopper 2 via the downflow guide portion 3 is guided to the inside of the rice guide body 11 through the rice inlet 12. Thereby, the inner surface of the rice guide body 11 constitutes a guide surface, and the rice which is carried in is guided from one side to the other side in the direction of the rotation axis.

In the rice M supplied from the rice supply unit 7, the plurality of blade bodies 14 are guided in the radial direction by the centrifugal force accompanying the rotation while being guided by the sliding guide surface 16 extending in the radial direction.

As shown in FIG. 6, FIG. 8, and FIG. 10, each blade body 14 is provided with a substantially U-shaped main body portion 14a formed of a plate-shaped metal material, and the main body portion 14a has a wide width at the center. A sliding guide surface 16 is formed. In addition to the main body portion 14a on which the slide guide surface 16 is formed, the back surface forming portion 14b forming the back side guide surface 17 is integrally coupled to the main body portion 14a on the side opposite to the slide guide surface 16. An opening 14c that widens in the circumferential direction toward the radially outer side is formed between the main body portion 14a and the back surface forming portion 14b.

Specifically, the collision surface 20 is inclined toward the downstream side in the rotational direction toward the outer side in the radial direction with respect to the sliding guide surface 16 .

The rice guiding member 21 is formed by integrally molding a soft material made of urethane as a soft synthetic resin. The hardness of the rice guiding unit 21 is set to a value lower than the hardness of the collar 9. When the hardness is too high, the rice is likely to be damaged. On the other hand, when the hardness is too low, there is a disadvantage that the shelling performance is lowered. Therefore, the hardness of the rice guiding unit 21 is set to an appropriate value according to an experiment or the like so that the possibility of damage to rice is small and the shelling performance is not lowered. Since the speed and the angle at which the rice collides with the collision surface 20 are easier to control than the collar 9, the husking performance can be maintained even if the hardness is set to be slightly lower.

As shown in FIGS. 6 , 11 , and 12 , the two sides of the rotation guide axis direction of the rice guiding member 21 are coupled to the respective support plates 18 and 19 by two bolts 22 . In order to reliably lock the rice guiding member 21 composed of a soft material, a metal internal thread member 23 is provided, and the female screw member 23 covers the outer peripheral portion of each bolt 22 and rotates throughout the rice guide assembly 21.

The rice guiding unit 21 is provided with a throwing action surface 28 that throws the processed object that has collided with the collision surface 20 toward the outer liner 9 . The throwing action surface 28 is formed in a state of being connected to the collision surface 20, and is inclined at a larger inclination angle than the collision surface 20 and more toward the downstream side in the rotation direction toward the radially outer side.

As shown in FIG. 10, by having the throwing action surface 28, the processed object colliding with the collision surface 20 is brought as close as possible to the tangential direction of the outer liner 9 by the throwing action of the throwing action surface 28. The angle is thrown towards the collar 9. As a result, when the treated material is thrown and collides with the collar 9, the impact force becomes low, and the possibility that the brown rice, the rice is shattered, or the part of the germ is detached to become a de-germinated state is less likely to be damaged.

As shown in FIGS. 8 and 10, the rice guiding unit 21 and the blade body 14 adjacent to the downstream side in the rotational direction are superposed in the rotational direction. Specifically, the rotation direction downstream end position L1 of the extending portion 21b of the rice guide unit 21 is located closer to the downstream side in the rotation direction than the upstream end position L2 of the blade body 14 adjacent to the downstream side in the rotation direction. position.

In this way, since the width of the rice passage portion 36 along the rotation axis direction is set to limit the width of one grain and one grain, the rice discharge portion is removed. The rice that has been discharged 13 is guided to a plurality of rice passage portions 36 that are aligned in the direction of the rotation axis in a state of being uniformly dispersed in the direction of the rotation axis. Thereby, the rice grains are dispersed in the direction of the rotation axis. By rotating the partition forming member 30 and utilizing the friction between the partition forming member 30 and the rice M, the posture of the rice can be unified into the posture in which the long dimension of the rice M is along the radial direction of the rice supply unit 7.

Since the radially outer end portion of the rice supply portion 7 is close to the radially inner end portion of the partition forming member 30, it is possible to prevent the rice discharge portion 13 from being discharged outward when dispersed in the direction of the rotation axis and enter a rice valley. After passing through the portion 36, the portions are moved toward the rice passage portion 36 adjacent to each other in the rotation axis direction.

Since the gap S for introducing rice is formed between the radially outer end portion of the rice supply portion 7 and the radially inner end portion of the slide guide member 31, the rice which is dispersed in the direction of the rotation axis is accompanied by the rotation of the impeller portion 6. The gap S between the rice supply unit 7 and the slide guide member 31 passes through and is dispersed in the circumferential direction. The rice M line is dispersed in the circumferential direction and sequentially guided into the rice passage portion 36 in one rice passage portion 36. The rice M system guided into the rice passage portion 36 is received by the radially disposed sliding guide member 31, and is guided radially outward by the centrifugal force accompanying the rotation.

As shown in FIGS. 13 and 14, since the radially outer end portions of the partition forming member 30 and the slide guiding member 31 are close to the radially inner end portion of the blade body 14, they are along the inside of each rice passage portion 36. The radially guided rice M does not interfere with each other and is guided directly toward the radially outer side of the blade body 14 in a rectified state.

In the blade body 14, the rice M guided by the dispersion guide 15 is continuously received, guided by the sliding guide surface 16 and guided by the slide, and guided radially outward by the centrifugal force accompanying the rotation. As shown in FIG. 10, the rice slidably guided by the sliding guide surface 16 is guided toward the collision surface 20 of the rice guide unit 21 while changing the orientation by the posture changing surface 26 formed at the radially outer end portion.

When the rice M collides with the collision surface 20, the shelling treatment is carried out by the impact, so that the rice M is separated into rice husks and brown rice. However, there is also a case where a part of the rice M remains without being shelled. The processed material including the rice husk, the brown rice, the untreated rice, and the like is thrown by the throwing action surface 28 toward the outer shim ring 9 along with the rotation of the impeller portion 6, and is again subjected to the husking treatment by the outer shim ring 9.

The processed object that has collided with the outer shim ring 9 is transported to the outside by a sorting device (not shown) by the transport guide portion 8a by the wind force generated by the rotation of the impeller portion 6 that rotates at a high speed. In the sorting device, a sorting process is performed to separate rice husks and brown rice. In addition, since the rice husking apparatus of the above structure can improve the husking rate, the sorting apparatus can omit the special sorting for sorting brown rice and untreated rice required for the conventional rice husking apparatus. The mechanism enables the miniaturization and structural simplification of the sorting device.

The rice shelling treatment is repeated, and when the member is worn by the rice collision, the worn member needs to be replaced. However, in the above configuration, the liner 9 and the blade body 14 which are large members are less likely to wear early, and the replacement frequency is high. Only the rice guiding element 21 is available, and it can be handled at low cost. The advantages.
