Concerning the structure of the wind separation section.

[Conventional technology]

The wind selecting section of this type of hulling machine is used to remove rice husks, rice husks, etc. from the treated material after hulling.

Conventionally, a sorting fan is provided so as to suction on the upper end side of the wind path, and the sorting wind is configured to simply flow along the wind selection path (for example, the applicant previously proposed. See Japanese Patent Application No. 1-215727).

[Problems to be Solved by the Invention]

In order to perform sufficient selection using only the wind selection route, it is necessary to make the length of the wind selection route sufficiently long, which is disadvantageous in that the size of the wind selection unit becomes large.

The present invention has been made in view of the above circumstances,
The purpose thereof is to make it possible to reduce the size of the wind selecting unit without deteriorating the selecting ability.

[Means for solving the problem]

The structure of the wind selecting section of the hulling machine according to the present invention is provided with a selecting fan that acts on the wind selecting path in an inclined posture in which the processed material flows down from the hulling section, and its characteristic configuration is It is as follows.

That is, upper and lower two-stage flow plates that are inclined in the same direction so as to guide the processed product in the same direction are provided, and the wind selection path is formed along each of the two vertical flow plates. The upper part of the wind-selecting path is suctioned by the fan, and the lower part of the wind-selecting path is provided with a rice cake collecting part for collecting rice cake. Then, the suctioned selection wind is provided so as to be blown from the lower end side to the upper end side of the wind selection path in a state of traversing the falling path of the sorted matter falling from the lower end of the wind selection path, The point is that a rice husk collecting unit is provided for collecting the rice husks flowing from the upper end of the wind selection path through the suction path of the fan.

[Work]

With the sorting fan, the sorting wind sucked from the upper end of the wind selection path is passed across the falling path of the sorted objects falling from the lower end of the wind selection path from the lower end of the wind selection path toward the upper end. By feeding under pressure, the sorting air is circulated and flowed in the air selection section.

The processed material that is supplied to the upper flow plate and flows down the lower flow plate is in the processed product in the process of being supplied to the upper flow plate and flowing down, and in the dropping process of falling from the lower end of the lower flow plate. Rice husks and rice porridge mixed in the air are blown away from the lower end of the upper wind-selection path part toward the upper end by the sorting wind, or blown away from the lower end of the lower wind-selection path part toward the upper end. To be done. Then, the rice porridge that has flowed to the lower wind-selection path portion is collected by the porridge collection unit.

In other words, the process of being supplied to the upper flow plate and flowing down,
It is now possible to make effective use of both the falling process that falls from the falling plate, and in the falling process, not only the rice husks, but also the rice husks having a higher specific gravity than the rice husks It is possible to efficiently remove and select using the route portion.

Further, since the sorting air sucked from the upper end of the wind sorting path is pressure-fed from the lower end side of the wind sorting path, the sorting wind can be efficiently sent to the falling path and the wind sorting path due to the dynamic pressure generated by the pressure feeding. Since the sorting air is circulated and flowed in the air sorting unit, it is possible to suppress the release of rice husks and dust out of the machine.

〔The invention's effect〕

Therefore, the process of being supplied to the upper flow plate and flowing down,
It becomes possible to make effective use of the falling process that falls from the falling plate, and in addition, in the falling process, not only the rice husks but also the rice husks having a specific gravity higher than that of the rice husks are efficiently removed and selected. Therefore, it is possible to shorten the length of the wind selection path without lowering the selection ability. In addition, since it is possible to efficiently blow the sorting air by the dynamic pressure generated by the pressure feeding, it is possible to avoid the problem that a sorting fan having a large capacity must be provided to blow a sufficient amount of sorting air for sorting. it can. Then, due to the synergistic effect thereof, the size of the wind selecting unit can be reduced as a whole.

Moreover, since it is possible to prevent the rice husks and dust from being discharged to the outside of the air separation section, it is possible to improve the dust-proof aspect.
