Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sorting device for sorting brown rice from mixed rice after hulling.

[Conventional technology]

A rotary sorting cylinder with a number of concave portions formed on its inner circumferential surface is installed horizontally, one end of which is used for supplying mixed rice of brown rice and paddy, and the other end used as a side for discharging paddy. On the other hand, a rotary grain sorting device in which a brown rice receiving trough with an open top surface extending in the axial direction of the sorting barrel is disposed in the rotary sorting barrel is disclosed in Japanese Patent Application Laid-Open No. 49-1991 as a prior art. It is disclosed in Japanese Patent No.-24746.

[Problem that the invention seeks to solve]

This rotary type 9'J grain sorting device scrapes the mixed rice fed into the sorting cylinder to the height achieved by the rotation of the sorting cylinder.
As the mixed rice moves to the discharge side while forming a layer, the brown rice is lifted up to a relatively high position while being stuck in the recess, and then falls down. , Utilizing the fact that the paddy of the mixed rice falls from a lower position than the brown rice, the brown rice falling from a higher position is received by the brown rice receiving trough and taken out, so this sorting action is performed correctly. For this purpose, the fluidized bed of the mixed rice must have a certain thickness.

In other words, when the thickness of the fluidized bed in the sorting river is thin, the trt joint is jgF5Ill inside the body and dances 1.
-・So.

When the phenomenon occurs, the brown rice cannot fit into the recess, resulting in poor sorting and poor performance.

Naturally? ), the above-mentioned t, v technology has J+, E・) in which the discharge side for sorting is open and the mixed rice is fed into the supply side, so the thickness of the flowing JI layer in the sorting stream is From the supply example, the discharge elongation gradually becomes thinner towards 1ζ, and becomes extremely thin near the discharge side, resulting in a significant decrease in sorting accuracy and performance near the discharge side. That's what happened.

The present invention solves the above-mentioned problems in the rotary grain sorting device disclosed in the above-mentioned prior art publication.

[Means for resolving issues]

Therefore, in the present invention, a rotary sorting cylinder is constructed with a large number of recesses formed on the inner circumferential surface, and one end of the rotary sorting cylinder is placed on the supply side for mixed rice of brown rice and paddy, and the other end is In the rotary grain sorting device, a brown rice receiving trough with a ten-sided open type extending in the axial direction of the sorting barrel is arranged in the rotary sorting river, while a part is formed on the paddy discharge side. A IIW plate with a ring zigza that projects inward is provided on the inner circumferential surface of the discharge side of the sorting cylinder. On the other hand, it is proposed that an outflow hole or notch be provided in a part of the circumferential direction of the seven-shaped weir plate.

[Operation of the invention/Senri] In this way, by having a total of 1k of fitO protruding inwardly on the inner circumferential surface of the discharge side in the iz separate case, the l cover plate on the 1st well side in the i Tatsumibetsu barrel is A certain amount of mixed rice will accumulate in the area, and the thickness of the mixed rice flow in the barrel will be 1 piece! I+! : Is it possible to prevent it from becoming thinner during storage 11-L'-2, supply a mixed rice fluidized bed of appropriate size to the sorting cylinder and discharge it from 1-1? 1
111 can be reliably formed.

Therefore, the sorting accuracy and capacity do not deteriorate near the discharge side of the sorting cylinder unlike in the prior art, and the entire part of the sorting cylinder from the supply side to the discharge side can be effectively used for sorting. It can direct the force and improve the sorting accuracy.
-It can be done.

However, if a weir plate in the shape of [shaped] is provided on the inner circumferential surface of the discharge side of the sea urchin sorting cylinder, if the sorting operation is stopped, the Mixed rice is T
'! 1F: Eject everything for Kokou'? If the rotation of the sorting cylinder is stopped, the mixed rice remaining in the sorting cylinder must be removed by hand, which requires a considerable amount of effort. The present invention solves this problem by providing the annular weir plate with an outflow hole or notch in the circumferential direction of the annular weir plate.

In other words, by providing the outflow holes or notches in the annular weir plate in this way, the mixed rice inside the sorting barrel is discharged outside the sorting barrel through these holes or notches during the sorting operation; Since the amount of mixed rice discharged is smaller than the amount of mixed rice supplied to the sorting cylinder, the action and effect of the weir plate can be maintained, while the sorting cylinder can continue to rotate for a while when the sorting operation is stopped. Since the mixed rice inside the sorting cylinder is discharged out of the sorting cylinder from this hole or notch, there is no need to manually shake out the residual mixed rice inside the sorting cylinder after the rotation of the sorting cylinder has stopped. This improves work efficiency.
