Japanese Patent Application Laid-Open No. 2003-19440

  In the above-described conventional configuration, when the weir is thrown outward from the radially outer end of the blade, the blade has an elongated shape, and due to the external shape of the weir, both end portions in the longitudinal direction become tapered. Depending on the condition of the heel against the radially outer end, the release direction may change or the release rate may fluctuate. As a result, the speed and angle at the time of collision with the liner may deviate from the state suitable for peeling, and in such a case, it may not be possible to peel well. That is, since the variation in the release direction and the release rate of the straw becomes large, there is a possibility that the yield can be reduced.

  Therefore, it has been desired to improve the peel rate in the impeller type hulling device.

The characteristic configuration of the hulling device according to the present invention is
A weir supply unit that discharges the weir carried in from the outside radially outward;
The crucible is provided along the outer periphery of the crucible supply unit so as to receive the crucible discharged from the crucible supply unit, and is rotated around a rotation axis located at the center of the crucible supply unit and discharged from the crucible supply unit. And an impeller portion for guiding the selected weir radially outward;
The impeller portion is positioned by a plurality of vanes radially extending radially inward from a radially inward side to a radially outward side, and the plurality of vanes are positioned radially outward on each of the plurality of vanes by the vanes. It has a plurality of inner stripping parts that receive guided gutters and take off by collision,
It is provided so that the outer periphery of the said impeller part may be enclosed, the outer shell part which receives the trap thrown in by the said impeller part, and which peels off by a collision is provided ,
The inner stripping portion comprises an impact surface intersecting the sliding guide surface of the blade body,
Between the sliding guide surface of the blade body and the collision surface, there is formed a posture changing surface which is inclined or curved so as to be positioned on the lower side in the rotational direction toward the radially outer side,
The concave surface is formed between the collision surface and the posture change surface in a state of being recessed with respect to the posture change surface .

  According to the present invention, the impeller portion guides the weir supplied by the weir supply portion in a radially outward direction by the centrifugal force accompanying the rotation while slidingly guiding the weir supplied by the weir supplying portion with a plurality of blade bodies. The crucible guided by the blade collides with the inner stripping portion provided on the radially outer side of the blade and the stripping treatment is performed.

  The inner stripping portion is provided in the impeller portion and rotates integrally with the blade, so that when the rotational speed is determined, the speed and angle when the weir guided by the blade collides with the inner stripping portion are There is no large fluctuation, and a stable variation is reduced. As a result, it becomes possible to suppress the fall of the pudding rate resulting from the magnitude | size of speed or angle dispersion | variation when a rice husk collides with a pudding part, and to improve a pudding rate.

  The weir which is guided by the blade is subjected to a peeling action at the inner peeling part and then thrown radially outward by the centrifugal force, collides with the outer peeling part and is again peeling action. You will receive Anther that has not been released at the inner stripping section can be released by impinging on the outer stripping section. Thus, it becomes possible to further improve the yield ratio by receiving a two-step release effect at the inner and outer release parts.

  Therefore, according to the present invention, it is possible to improve the blasting rate in the impeller type hulling apparatus.

Further , according to this configuration, the wedge guided radially outward by the centrifugal force while slidingly guiding on the sliding guide surface of the blade is moved to the radially outward side by the posture changing surface After the posture is changed to the lower side in the rotational direction, a collision treatment is performed on a collision surface intersecting with the sliding guide surface to carry out the stripping treatment.

  By the way, the cocoon has a slender shape having a bulged body part between the tapered one end portion where the germ is present and the opposite end side portion located on the opposite side of it. There is. The one end portion is harder than the other portions and is less likely to be broken.

  When the blade is configured such that, for example, the weir is guided only by the flat sliding guide surface to collide with the inner stripping portion, when the weir is guided with the longitudinal direction along the sliding guide direction In the state where the one end portion is at the beginning, the inner side peeling portion may collide. If such a collision is repeated, the hard part in the weir may collide, and the inner spatula may be worn significantly in a short period of use.

  According to the present configuration, even when the one end portion is at the beginning and guided by the sliding guide surface, as the wedge is moved radially outward by the posture change surface, the rotation direction becomes lower. Since it is guided while changing its direction to the side, the torso's torso collides with the collision surface. As a result, it becomes easy to avoid that the hard part of a bag collides with the inside stripping part.

  Therefore, it is possible to maintain a good use condition over a long period of time by avoiding repeated collisions of the hard portion of the bale against the inner side peeling portion and large wear in a short period of use.

  In the present invention, the treatment object after colliding with the collision surface is directed to the outer side peeling portion so that the inner side peeling portion is inclined so as to be positioned on the lower side in the rotational direction toward the radially outer side. It is preferable that a throwing action surface be provided, and an inclination angle of the throwing action surface to the sliding guide surface be set larger than an inclination angle of the collision surface to the sliding guide surface.

  According to this configuration, the weir guided by the blade collides with the collision surface of the inner stripping portion and receives the stripping action, and the treated material is thrown toward the outer stripping portion by the throwing action surface. Since the inclination angle of the throwing action surface to the sliding guide surface is larger than the inclination angle of the collision surface to the sliding guide surface, the processed material is directed to the outer stripping portion at an angle as close as possible to the tangential direction of the outer stripping portion. Be released.

  As a result, when it is released and collides at the outer exfoliation part, the impact force is low, and the brown rice and the straw are damaged at the collision, for example, the brown rice and the straw are broken or the germ part is detached and the sprouting occurs It becomes easy to avoid becoming a state. In addition, when the kite rebounds at the outer side peeling section, the kite does not rebound vigorously, and there is little risk that the inner side stripping section will be vigorously hit again to cause damage to the base.

In the present invention, the rotating direction downstream side end of the inner husking portion, wherein the sail body of the rotating direction times than the upstream side end adjacent the rotating direction downstream side with respect to the inner husking portion It is preferable to be located on the lower side in the rolling direction.

  According to this configuration, the inner stripping portion and the blade adjacent to the lower side in the rotational direction overlap in the rotational direction (circumferential direction). It is possible to prevent the reeds bouncing back after colliding with the outer side peeling portion from entering from the gap between the inner side peeling portion and the blade adjacent to the lower side in the rotational direction. As a result, it is easy to avoid the disadvantage that the weir enters from the gap and interferes with the weir which is slide-guided by the blade body so that the peening treatment can not be properly performed.

  In the present invention, it is preferable that a guide surface set substantially in parallel with the inner circumferential surface of the outer side stripping portion is formed at the radially outer end portion of the inner side stripping portion.

  According to this configuration, even if the heel that has bounced back after colliding with the outer side peeling portion abuts against the radially outer end portion of the inner side peeling portion, it is substantially the same as the inner circumferential surface of the outer side peeling portion Since the guide surfaces set in parallel are formed, there is little risk that the heel will be damaged by a strong impact.

In the present invention, it is preferable that a projection that protrudes radially outward and that extends in the direction of the rotation axis is formed at the radially outer end of the inner stripping portion.

  According to this configuration, when the inner stripping portion is rotated as the impeller portion rotates, the weir that has been subjected to the stripping action at the inner stripping portion is the passing location of the inner stripping portion and the outer stripping portion When being thrown into the passage area between the pots, the projections rotating integrally with the inner stripping part push away the pieces which have already been thrown and pass through the passage part through the pots. It becomes easy to avoid the disadvantage that the processing is not properly performed.

  In the impeller type huller, there is a tendency that the plurality of weirs passing through the weir passage region tend to gather in a state of being biased to the center side in the rotational axis direction in the impeller portion. However, according to the present configuration, the wind is generated by the rotation of the wide protrusion in the direction of the rotation axis, and the air flow acts on the plurality of weirs passing through the weir passage area to eliminate the unevenness of the weirs And can be leveled in the direction of the rotational axis. As a result, it is possible to suppress uneven wear of the outer spat.

  That is, as shown in FIGS. 2, 4 and 5, the weir supply unit 7 is provided in line with the downstream side of the guiding direction of the flow-down guide unit 3 and coaxially centered on the rotation axis X of the impeller unit 6. It has a cylindrical rod guide body 11 located at. The weir guiding body 11 has a width such that the axial width thereof corresponds to the width of the impeller portion 6 in the rotational axial direction. In the crucible guide body 11, a crucible inlet 12 is formed on one end side in the axial direction, and the other end side in the axial direction is closed by a side wall portion 10. The side wall portion 10 doubles as a bearing portion for rotatably supporting a drive shaft 41 described later. The crucible discharge portion 13 is formed by opening a partial region of the crucible guide body 11 in the circumferential direction. The crucible discharge portion 13 is wide along the rotational axis direction and opens about 90 degrees along the circumferential direction (see FIG. 8).

  As shown in FIG. 9, a communication connection is established between the hopper 2 and the downstream guide 3 so that the crucible M guided downward through the downstream guide 3 is guided to the inside of the crucible guide body 11 through the crucible inlet 12. It is done. Therefore, the inner surface of the weir guide body 11 constitutes a guide surface for guiding the weir carried in from one side in the rotational axis direction to the other side.

The hardness of the wedge guide block body 21 is set to a value lower than the hardness of the liner 9. If the hardness is too high, the wrinkles may be damaged. On the other hand, if the hardness is too low, there is a disadvantage that the peening performance is reduced. Therefore, based on experiments and the like, the hardness of the weir guiding block 21 is set to an appropriate value so that there is little risk of damage to the weir and that the peeling performance is not lowered. Since the speed and angle at which the wedge collides with the collision surface 20 is easier to control than the liner 9, it is possible to maintain the release performance even if the hardness is set to a lower value.
