Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a method of dehulling paddy in a hulling section, wind sorting the rice husks in a wind sorting section, and then sorting and taking out only brown rice. This relates to a sliding sorting device.

[Conventional technology]

Conventionally, this type of huller sorting equipment has often adopted a swinging type sorting mechanism for sorting brown rice, but this swinging type sorting mechanism is large and generates a lot of vibration and noise. JP-A-49-1999 as a prior art because it has the following drawbacks:
Publication No. 24745 discloses a rotary sorting mechanism comprising a brown rice receiving trough in a horizontal rotary sorting cylinder with a large number of four-part recesses formed on the inner circumferential surface, for sorting brown rice from fallen rice after culling. is proposed to be used.

[Problem that the invention seeks to solve]

However, in the rice hulling and sorting device described in this publication, the washed rice is supplied to one end of the sorting cylinder in the rotary sorting mechanism close to the hulling part, and the other end of the sorting cylinder is used as the discharge side of the paddy, and the rice is removed from the hull. The paddy discharged from the discharge side is returned to the culminating section so as to be culminated again via a transfer means disposed outside the sorting cylinder.

The overall size of the hulling and sorting device is increased by the fact that the transfer means for returning and transporting the rice discharged from the sorting barrel to the tax weighing section is provided on the outside of the sorting barrel. It had the disadvantage of being large.

The present invention provides a hulling sorting device using a rotary sorting mechanism for sorting brown rice as described above, in which the interior space of the sorting barrel in the rotary sorting mechanism is used for installing a grain transfer means. This avoids increasing the size of the sorting device.

[Means for solving problems]

Therefore, in the present invention, a rice husk winding section for removing rice that has fallen from the hulling section is provided at the lower part of the hulling section, while a large number of rice husks are arranged on the inner circumferential surface on the sides of the hulling section. A rotary sorting mechanism equipped with a brown rice receiving trough within a horizontal rotary sorting barrel formed with a concave portion is arranged such that one end of the sorting barrel in the rotary sorting mechanism is located on the hulling section side. In the hulling and sorting device, one end of the rotary sorting cylinder of the rotary sorting mechanism is made to be the paddy discharge side and communicated with the paddy supply point in the hulling section, while the other end of the rotary sorting cylinder is connected to the paddy discharge side. A transfer means is provided in the sorting barrel to supply the mixed rice after the rice husks have been sorted in the wind sorting section to the supply side.

[Effect]

The paddy supplied to the deweighing section is deculled in the deweighing section.Then, the husks of the husked rice after deculling are sorted and removed in the wind sorting section, and then put into the sorting barrel of the rotary sorting mechanism. Using the installed transfer means, the liquid is sent into the supply side at the other end of the sorting cylinder, is scraped up to a height created by the rotation of the sorting cylinder, and then falls to the bottom, repeatedly forming a layer while moving to the discharge side. During the process, the brown rice fits into the recess on the inside of the sorting cylinder and is lifted up to a relatively high place, and then falls from the recess, entering the brown rice receiving trough and being taken out of the machine. Paddy is discharged from the discharge side at one end, and this paddy is supplied to the m weighing section and subjected to the culling operation again.

〔Effect of the invention〕

In this way, the present invention makes one end of the rotary sorting cylinder of the rotary sorting mechanism close to the deweighing part the paddy discharge side, while discharging the mixed rice from the wind sorting part at the lower part of the deculverting part to the other side of the sorting cylinder. Since the transfer means for transferring and feeding grains to the feed side at the end is provided in the sorting cylinder, it is not necessary to provide a kth transfer means for transferring grains on the outside of the sorting cylinder as in the prior art. Because of this, the entire hulling and sorting device that uses a rotary sorting mechanism for sorting brown rice can be made smaller and lighter in weight. The brown rice in this mixed rice is subjected to sorting action over a long period of time from the supply side to the discharge side of the sorting barrel, so the mixed rice after hulling is fed to the supply side of the sorting barrel. As in the case where rice is distributed and fed from rice to the discharge side, the time for sorting the brown rice in the mixed rice becomes shorter, and the amount of brown rice remaining in the paddy discharged from the discharge side of the sorting barrel increases. It has the effect of preventing this.
