Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a rice hulling and sorting device that combines a culminating section, a wind sorting section, and a rotary sorting mechanism.

[Conventional technology]

Conventional huller sorting equipment often uses a swinging type sorting mechanism to sort brown rice from the rice that has been washed out after wind sorting, but this swinging type sorting mechanism is However, for the reason that it has drawbacks such as large vibration and noise, Japanese Patent Application Laid-Open No. 49-24745 as a prior art proposes a method using a large number of depressions on the inner circumferential surface for sorting brown rice from crushed rice. It is proposed to use a rotary sorting mechanism comprising a brown rice receiving trough inside a horizontal rotary sorting cylinder with a concave shape.

[Problem that the invention seeks to solve]

However, in the rice hulling and sorting device described in this publication, the grained rice is supplied to one end of the sorting cylinder 2 adjacent to the hulling part of the rotary sorting mechanism, and the other end of the sorting cylinder is used as the paddy discharge side. ,
The paddy discharged from the discharge side is returned to the culling section through the grain transfer means disposed outside the sorting cylinder and is culled again, so that the whole hulling and sorting device is The size of the grain transfer means that recirculates and transfers the paddy discharged from the sorting cylinder to the culvert is increased by the fact that it is provided on the outside of the sorting cylinder. There is a drawback.

In addition, since a considerable amount of brown rice remains in the brown rice receiving trough when the hulling work is interrupted or completed, this residual brown rice may be scraped out by hand from the brown rice receiving trough or removed from the brown rice receiving trough. It also had the disadvantage of having to be removed and cleaned.

The present invention provides a rice hulling sorting device using a rotary sorting mechanism for sorting brown rice as described above, in which the internal space of the sorting cylinder in the rotary sorting mechanism is used for installing a grain transfer means. The disadvantages of the prior art described above are improved by making it possible to discharge the grains remaining in the transfer means installed in the sorting cylinder and the brown rice receiving trough into the sorting cylinder.

[Means for solving problems]

For this reason, in the present invention, a wind screening section is provided at the lower part of the culminating part to remove the rice that has fallen from the culminating part, and a large number of depressions are formed on the inner peripheral surface on the sides of the culminating part. A rotary sorting mechanism having a brown rice receiving trough extending in the axial direction of the rotary sorting cylinder is disposed such that one end of the sorting cylinder of the rotary sorting mechanism is adjacent to the culling part. In the sliding sorting device, one end of the sorting cylinder of the rotary sorting mechanism is made to be the paddy discharge side and communicated with the paddy supply section in the culling section, while the other end of the sorting cylinder is connected to the paddy discharge side. A transfer gutter for transferring and supplying the fallen rice to the supply side into the body is provided in the sorting cylinder, and the bottoms of the transfer gutter and the brown rice receiving gutter are provided with a groove in the longitudinal direction. Each of the drop ports is provided with a bottom valve that can be opened and closed.

[Effect]

The paddy supplied to the culling section is deculled in the deweighing section, and after the culling, the rice husks are sorted and removed in the wind sorting section. The waste is sent to the supply side at the other end of the sorting cylinder through the transfer trough, is scraped up to a height created by the rotation of the sorting cylinder, and then falls to the bottom, repeating the flow and moving to the discharge side while forming a fluidized bed. During the process, the brown rice is lifted up to a relatively high position while being fitted into the recess on the inner peripheral surface of the sorting cylinder, and then falls from the recess, entering the brown rice receiving gutter and being taken out of the machine. On the other hand, paddy is discharged from the discharge side at one end of the sorting cylinder, and the paddy is returned to the deweighing section via the paddy supply section in the culling section, where it is subjected to the culling operation again.

When interrupting or finishing the hulling work, after stopping the supply of paddy to the culling section, the bottom valves for the drop openings at the bottoms of the brown rice receiving trough and transfer trough are opened, and the brown rice receiving trough and transfer trough are opened. All of the brown rice or paddy grains remaining inside are discharged from the drop opening into the sorting cylinder.

〔Effect of the invention〕

As described above, the present invention makes one end of the rotary sorting cylinder of the rotary sorting mechanism adjacent to the culling section the discharge side to the paddy supply section in the culminating section, and the lower part of the culminating section. By disposing a transfer gutter in the sorting cylinder for transferring and supplying the rice that has fallen from the wind sorting section to the supply side at the other end of the sorting cylinder, the outside of the sorting cylinder has the above-mentioned prior art. Since there is no need to provide a grain transfer means for transferring grains from one end of the sorting cylinder to the other, the entire hulling sorting device using a rotary sorting mechanism for sorting brown rice can be Not only can it be made smaller, but it can also be made lighter.

Moreover, the present invention provides a drop opening with a bottom valve that can be opened and closed in the longitudinal direction at the bottom of the brown rice receiving trough and transfer trough provided in the sorting cylinder of the rotary sorting mechanism, thereby interrupting the hulling operation. Alternatively, at the time of completion, all the grains remaining in the brown rice receiving gutter and the transfer gutter can be released in one go by opening the bottom valve, and the remaining grains in both these receiving gutter can be scraped out by hand. Alternatively, since it is possible to omit the work of removing both receiving troughs, the provision of a transfer trough in addition to the brown rice receiving trough within the sorting cylinder eliminates the need for significant effort in cleaning work at the time of interruption or completion of hulling work. This has the effect of reliably avoiding this and improving work.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings of the embodiments. A is a culling section, which is composed of a paddy supply hopper 1 and a pair of culmming rolls 2, etc., and B is a wind selection section, where the paddy is removed from the culmming section A. It controls the wind sorting of rice and the wind sorting of brown rice sorted by rotary sorting mechanism C, which will be described in detail later. 3 is a barrel for fried rice and 4 is a barrel for fried finished brown rice.

The rotary sorting mechanism C separates the fallen rice that has been subjected to the culling removal process in the culling part A and the wind sorting part B into brown rice and paddy,

Inside the body 5 is a brown rice receiving gutter 8 with a built-in screw conveyor for receiving the brown rice that fits into the recess a and is lifted up to a high position, and extends parallel to the transfer gutter 7 in the axial direction of the sorting cylinder 5. and the discharge side Y of the primary sorting cylinder 5 is connected to the paddy supply hopper 1 in the deweighing section A, and the paddy discharged from the discharge side Y of the sorting cylinder 5 is transferred to the paddy supply hopper 1. 1. Look into the room.

Further, inside the secondary sorting cylinder 6, a finished brown rice receiving trough 9 is installed horizontally for receiving the finished brown rice that fits into the recess a and is lifted up to a high position.

In the figure, reference numerals 10 and 11 denote a communication gutter 12 which is provided on the supply side X and allows the brown rice received in the brown rice receiving gutter 8 in the primary sorting cylinder body 5 to flow into the supply side X in the secondary sorting cylinder body 6. 13 is a circulation path that communicates the discharge side Y of the secondary sorting cylinder 6 with the dropped rice frying cylinder 3, and 13 is a finished brown rice catcher 9 in the secondary sorting cylinder 6.
This is a passage for leading out the finished brown rice inside onto the flow plate 14 of the wind sorting section B.

The symbol T in the figure is a supply tank for dropped rice, which is attached to the side wall 15 on the upper side of the culling section A, that is, on the discharge side Y, and the supply tank T
The lower part thereof communicates with the starting end of the transfer gutter 7 in the primary sorting cylinder 5, and the tip of the dropped rice lifting cylinder 3 is inserted into the ceiling 16 of the supply tank T.

Next, reference numeral 17 in the figure indicates a drop opening provided at the bottom of the brown rice receiving trough 8 in the primary sorting cylinder 5 so as to extend in the longitudinal direction; It is a bottom valve that rotates in a fan shape around the support shaft 19 of the tank T to open and close the drop port 17, and also includes the transfer gutter 7 whose starting end communicates with the lower part of the supply tank T as described above, and the secondary sorting. Cylindrical body 6
A drop opening extending in the longitudinal direction is also provided at the bottom of the finished brown rice receiving gutter 9 in the transfer gutter 7 and the finished brown rice receiving gutter 9, and the supporting shaft 20. A bottom valve that opens and closes the drop port using 21 as a fulcrum is attached to each of them.

Incidentally, the bottoms of the receiving pipe 8.9 and the transfer gutter 7 may be formed into a concave shape, and a bottom valve may be built into each of the concave portions.

Of the respective support shafts of these bottom valves, the support shaft 19.20 has an arm rod 22.23 at the end of the discharge side Y, and the support shaft 19.21 has an arm rod 22.23 at the end of the supply side X. The rods 24 and 25 are each fixed, and the other ends of the arm rods 22 and 23 are connected to each other by a continuous rod 26 on the discharge side Y, and the other ends of the arm rods 24 and 25 are connected to each other by a continuous stroke 28 on the supply side X. connected.

The arm rod 22 has an inverted shape, and the side wall 1 is attached to the bent part.

has been done.

Therefore, during the hulling operation, the paddy supplied into the paddy supply hopper 1 in the culling section A is sequentially removed by a pair of culm removing rolls 2, and then wind-selected in the wind-selecting section B. , the rice is lifted into the supply tank T by the lifted grain cylinder 3. The lifted dropped rice is transferred to the supply side X by the transfer gutter 7, and then sequentially falls into the primary sorting cylinder 5 from the other end of the transfer gutter 7.

This dropped rice is scraped up to a height created by the rotation of the primary sorting cylinder 5, and then falls to the bottom repeatedly.
While moving toward the discharge side Y while forming a fluidized bed, the brown rice among the fallen rice is lifted up to a relatively high position while being stuck in the depression a, and then falls from the depression a. Enter brown rice receiving channel 8.

The brown rice that has entered the brown rice receiving gutter 8 in this way passes through the communication gutter 10.11 from the other end to the supply side X in the secondary sorting cylinder 6.
A secondary screening action is carried out. The sorting action within the secondary sorting cylinder 6 is similar to that of the primary sorting cylinder 5, but
This secondary sorting cylinder 6 is adjusted so that only brown rice enters the finished brown rice receiving trough 9.

The dropped rice in the primary sorting cylinder 5 flows as it moves toward the discharge side Y, and the amount of rice increases.
The rice is returned from the end to the paddy supply hopper in the deweighing section A,
The culling process is carried out again. On the other hand, a mixture of paddy and brown rice is discharged from the Y end of the discharge side of the secondary sorting cylinder 6, and this mixture flows down in the circulation path 12 and is returned to the supply tank T. lifted up inside. In addition, the finished brown rice that has entered the finished brown rice receiving channel 9 in the secondary sorting cylinder 6 is transferred to the passage 13.
After flowing down onto the flow plate 14 and being air-selected in the air-selecting section B, the finished brown rice is taken out of the machine from the frying tube 4.

By the way, when interrupting the rice hulling work or finishing the work, loosen the knob 27 and move the tip of the knob 27 that was pressed against the side wall 15 away from the side wall 15. When the bottom valve 18 of the brown rice receiving trough 8 is rotated to the position shown in the imaginary line shown in FIG. 4, the drop opening 17 is opened.

Also, when this knob 27 is rotated to the left, it is also turned to the discharge side Y.
In this case, the arm rod 23 is interlocked via the continuous stroke 26, and the supply side
In the case of armrest 24. The connecting rod 28° works in conjunction with the arm rod 25 to open the drop ports at the bottom of each of the transfer gutter 7 and the finished brown rice receiving gutter 9.

By doing so, the fallen rice that is being transferred in the transfer gutter 7 and the fallen rice that is about to enter the transfer gutter 7 from the supply tank T will immediately enter the primary sorting cylinder 5 from the drop opening at the bottom of the transfer gutter 7. At the same time, the brown rice in the brown rice receiving trough 8 will also be released into the primary sorting cylinder 5 from the drop port 17 at the bottom, and the brown rice in the finished brown rice receiving trough 9 will also be released into the primary sorting cylinder 5 from the drop port 17 at the bottom. It will be discharged into the secondary sorting cylinder 6 from the drop port.

As mentioned above, the grains discharged from each receiving gutter into the two sorting cylinders 5゜6 and the remaining grains in the sorting cylinders can be removed by continuing the rotation of both the sorting cylinders for a while. Discharge side Y
Most of the material is discharged from the
