  In the above-described conventional configuration, since the hulling processing unit and the wind separation processing unit are provided in the state located on the inward side of the housing, for example, inspection of a portion or a fan where peeling is performed in the hulling processing unit When performing maintenance work such as repair, it is necessary to perform a large-scale operation such as disassembling each device by releasing connection of each part of the housing, which is disadvantageous in that it becomes troublesome. In addition, since the hulling processing unit and the wind selection operating unit are disposed in the vertically overlapping state, the size becomes large in the vertical direction, and the work position becomes high, which may make it difficult to perform maintenance work. There is also.

  Therefore, there has been a demand for a hulling apparatus which can easily perform maintenance work.

The characteristic configuration of the hulling device according to the present invention is
An impeller type hulling processing unit that has a plurality of blades that rotate around the horizontal axis, and that peels out the straw.
A particle guiding portion for guiding the supplied particles to be treated to the hulling portion;
A wind selection guide unit for flowing and guiding the processed material from the hulling processing unit in which brown rice and rice husk are mixed;
A fan which rotates around an axis parallel to the horizontal axis, and causes the wind selecting guide to act on the treated material flowing down to separate the treated material into brown rice and rice husk; Equipped
While being provided with the particle guide portion and the wind selection guide portion aligned in the lateral direction, the hulling processing portion and the wind selection operating portion are provided in the device lateral outer portion in the horizontal alignment state. is there.

  According to the present invention, the supplied particles to be treated are guided by the particle guiding unit and supplied to the hulling processing unit. In the impeller type hulling processing unit, the blade rotating around the horizontal axis bounces off the particles to be treated in the radial direction, and the particles to be treated collide with the receiving member on the radially outer side to remove the particles. Processing is performed. The processed material that is expelled by the hulling processing unit and discharged is in a state where brown rice and rice husk are mixed. In the wind selection guide section, the processed material from the hulling section is flowed down, and the sorting wind generated by the fan provided in the wind selection section acts to blow off the light rice husk by the wind, which is heavy. Brown rice is separated downward into brown rice and rice husk by flowing downward.

  The particle guiding portion and the wind selection guiding portion are entirely surrounded by a casing in order to create a guiding path for guiding the particles to be treated and a ventilation path for passing the sorted air. Since the grain guiding portion and the wind selection guiding portion which are easily surrounded by such a housing and are easily arranged in a line are provided in the lateral direction, the vertical size of the apparatus can be made compact.

  Since the hulling processing unit and the wind separation processing unit are provided side by side in the lateral side of the apparatus, these are arranged side by side on one lateral side of the housing that accommodates the particle guiding unit and the wind selection guiding unit. Can be deployed. That is, since the hulling processing unit and the wind selection operating unit are provided facing the outside of the device, when performing maintenance work such as inspection and repair, troublesome work such as releasing connection of each part of the housing is unnecessary. Can be easily performed from the outside of the apparatus. Further, by making the upper and lower dimensions of the device compact, maintenance work can be performed at a low position, and there is also an advantage that the work can be performed easily.

  In the present invention, a communication portion connecting the outlet of the hulling portion and the inlet portion provided in the upper portion of the wind selection guiding portion is between the hulling portion and the wind sorting portion. It is preferable to pass through.

  According to this configuration, in the impeller-type hulling processing unit, the processing product in which the brown rice and the rice husk are mixed is vigorously discharged by the blowing force of the plurality of rotating blade bodies, so using the blowing force The processing object is transported from the outlet portion of the hulling processing portion toward the inlet portion provided on the upper portion of the wind selection guiding portion through the communication portion.

  Since the communication part is provided utilizing the gap between the hulling processing part and the wind separation processing part provided in the side by side condition, on the outer side in the alignment direction of the hulling processing part and the wind separation processing part The communication portion can be compactly provided without protruding.

  In the present invention, it is preferable that a power transmission unit is provided that transmits and couples the rotary member for hulling of the hulling processing unit and the rotary member for air blowing of the wind separation unit.

  According to this configuration, when the switching mechanism is switched to the first supply state, the particles to be treated supplied to the inlet portion are supplied to the particle guiding portion, and the hulling process is performed. When the switching mechanism is switched to the second supply state, the particles to be treated supplied to the inlet are supplied to the wind selection guiding unit, and the wind selection process is performed without the hulling process.

  If the particles to be treated are soot, the hulling process is performed by setting the first supply state, and then the chaff is removed by the wind selection guide. On the other hand, if the grain to be treated is brown rice, the foreign matter is removed by performing the hulling process by setting the second supply state.

  Therefore, if it is applied not only to hulling processing but also to equipment that performs milling processing as post-processing, by switching the switching mechanism, it is possible to perform appropriate processing whether it is mulberry or brown rice It becomes possible.

The switching motor is provided on the outer side of the apparatus on the side where the hulling processing unit and the wind separation processing unit are present. Therefore, when performing maintenance work such as inspection and repair of the switching motor, connection of each part of the casing is required. There is no need for troublesome work such as releasing, and it can be easily performed from the outside of the apparatus.
