[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is based on the idea that the paddy extract from the extractor is selected by air in the wind selector, and the mixed grains of brown rice and rice after the wind selection are passed through a mill. In an even distribution device for the mixed kernels in a hulling machine or the like that feeds to a rotary sorting unit provided with a plurality of sorting cylinders that form a large number of pot holes on the inner peripheral surface to sort and brown rice. Available.

[0002]

2. Description of the Related Art Conventionally, as described above, a huller made up of a dewatering section, a wind selection section, a rotary selection section, a grain-lifting machine, etc. An apparatus which is composed of a plurality of sorting cylinders having holes formed therein, and in which each of the sorting cylinders uniformly distributes and supplies the mixed kernel after the wind selection to improve the performance of the rotary sorting section is disclosed in, for example, Shokai Sho 62 -27736.

[0003]

[Problems to be solved by the present invention] However, such as the mixed grains after the air removal by the huller, there is a certain degree of variation in the grain, and the waste is mixed into the grain. In the present invention, it is difficult to evenly distribute the seeds in the distribution channel due to the flow rate difference due to the caught in the grain channel or on the partition plate for distribution. The present invention has been devised with the aim of providing a device that eliminates the trapping of straw debris that has been mixed in the grain in the partitioning plate each time and does not hinder uniform distribution to the distribution channel. It is a thing.

[0004]

In order to achieve the object described in the preceding paragraph, the present invention has the following configuration. In other words, in the case where a partition plate is erected in the width direction intermediate portion of the grain flow path and the grains flowing through the flow path are distributed to a plurality of grains, the grains flowing upstream of the partition plate are pressed from above. Then, a leveling member for leveling the thickness of the fluidized bed was provided, and the partition plate was formed in a substantially triangular shape in a side view, and the upper edge thereof was gradually increased from the upstream side with respect to the flow of the grain. In addition to the guide edge, the upper portion on the downstream side of the partition plate is configured as an inclined portion inclined toward one of the distribution channels.

[0005]

According to this structure, the grain flowing through the grain flow path is first flattened in the width direction by the pressing from above by the leveling member, and the smoothed layer is separated by the partition plate. It is split and distributed to each distribution channel. Then, at that time, the straw waste mixed into the grain separated and separated by the partition plate is caught so as to straddle the guide edge of this partition plate, but the caught straw waste is transferred to the subsequent grain. As it is pushed, the guide edge is raised and rises from the fluidized bed, reaches the inclined part, falls from here to one distribution channel, flows with the shunted grain, and the straw waste remains caught Or
The phenomenon that the waste that flows later is not further trapped thereon does not occur and the function of the partition plate is not hindered, so that the distribution can be performed equally to both distribution channels.
