Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a residual grain removal device in a rotary sorting huller comprising a dehulling section, a wind sorting section, and a pot-hole type rotary sorting section.

In particular, the present invention has devised a means for easily and quickly taking out the grains remaining in the sorting barrel constituting the pot-hole type rotary sorting section of this rotary sorting huller.

BACKGROUND TECHNOLOGY In the case of a huller equipped with a pot-hole type rotary sorting section as described above, in order to remove the grains remaining in the sorting barrel, the feed side is lifted up and the discharge side is lowered and tilted slightly. This facilitated the removal of the remaining grains to some extent. For example, it has a configuration as shown in Japanese Patent Application Laid-Open No. 10346/1983.

With this configuration, the entire machine body was tilted using wheels for movement, thereby lowering the discharge side of the sorting cylinder and promoting the flow of residual particles toward the discharge side. Not only does it take a considerable amount of time to complete removing the remaining particles, but also the above-mentioned tilting operation of the machine is not easy.

Problems to be Solved by the Invention As described above, in the conventional technology, not only does it take a considerable amount of time to remove the grains remaining in the sorting barrel, but it also requires an operation to tilt the machine. There were problems such as it was not easy to do so.

Therefore, the present invention attempts to solve the above-mentioned problems with the conventional method when taking out the remaining grains, and instead of tilting the machine body, we have devised a new design on the back side of the partition plate, which is pivoted to the grain receiving side of the receiving trough. The purpose is to allow the remaining grains to be easily and quickly removed by receiving the grains scooped up and released through the hole in the pot by the back surface and transferring them to the discharge side.

Means for Solving the Problems Therefore, the present invention provides a rotary sorting huller comprising a dehulling section, a wind sorting section, and a pot-hole type rotary sorting section.
The lower end is attached to the back side of a partition plate whose lower edge is pivotally attached to the grain receiving side of a receiving gutter that is inserted into the sorting barrel that constitutes the pot-hole type rotary sorting unit and is suspended horizontally so that the inclination angle can be changed and adjusted. A feed plate is provided that is inclined toward the discharge side, and the partition plate is tiltable toward the receiving gutter side so that the upper part of the receiving gutter can be closed.

With this configuration, during the hulling operation, the partition plate maintains an appropriate inclination angle and guides only the brown rice, which is scooped up through the pot hole and falls in a parabolic pattern, into the receiving trough. At the end of the hulling operation, or when changing the type of rice to be hulled, when you want to take out the grains remaining in the sorting barrel, remove the above partition plate from the receiving ditch. When the grains remaining in the sorting barrel are scooped up by the pot hole and discharged, they are caught by the back side of this partition plate and then moved by the tilting feed plate. They are forced to move to the discharge side and fall into the sorting cylinder. By repeating the scooping up by the pot hole and the transfer action by the feed plate, the particles remaining in the sorting cylinder are quickly transferred to the discharge side and taken out.

Example The present invention will be explained below based on examples.

A is a removing section, B is a wind sorting section, and C is a pot-and-hole type rotary sorting section.The removing section A and a pot-and-hole type rotary sorting section C are arranged before and after the wind sorting section B to make a rotary sorting huller. It is composed of

The de-rolling section A is equipped with a paddy tank 1 and a pair of de-rolls 2, and in the front part of the wind sorting section B, the de-rolled material from the paddy de-rolling section A is sorted through a sorting air passage 3, and dust such as paddy grains is sucked and discharged. The rice cake is discharged from the machine 4 to the outside of the machine, and the rice cake is taken out of the machine from the rice cake outlet 6 through the rice cake outlet 5 to obtain a mixture of brown rice and paddy. At the rear, brown rice is sorted out from the mixture by a pot-and-hole type rotary sorting section C to remove small rice.

The pot hole type rotary sorting section C has receiving troughs 9 and 10 arranged side by side in a sorting cylinder 8 which is rotatably suspended horizontally with a large number of pot holes 7 formed in its inner peripheral surface. This receiving gutter 10 is located on the grain receiving side Z of the sorting cylinder 8 which rotates in the direction of the arrow of the receiving gutter 9, and both have a V-shape and each grain receiving side Z
are provided with partition plates 11 and 12 whose lower edges are pivotally connected and whose inclination angle can be adjusted freely, and a screw conveyor 13 for transferring grains from the supply side X to the discharge side Y is installed in the receiving gutter 9. In the gutter 10, there is a line from the discharge side Y to the supply side X.
A screw conveyor 14 is installed inside each of the receiving channels 10, and a drop port 15 is provided on the supply side X of the receiving gutter 10.

On the back side of the partition plates 11 and 12, as shown in FIG.
6 and 17 are installed diagonally at equal intervals,
Furthermore, the partition plates 11 and 12 are constructed so that they can be tilted toward the receiving troughs 9 and 10, respectively, using their pivotally connected lower edges as fulcrums, as shown in FIG. 4, to close the tops of the receiving troughs 9 and 10.

The one shown in FIG. 5 shows another embodiment of the receiving troughs 9, 10, in which the bottoms of the receiving troughs 9, 10 are opened and on-off valves 18, 19 which can be opened and closed are provided in these openings. belongs to.

Reference numeral 20 denotes grain lifting blades attached to the inner circumferential surface of the discharge side Y end of the sorting barrel 8 at equal intervals. Reduction gutter 2 that receives paddy and returns it to tank 1
1 is installed diagonally, 22 is a thrower that lifts the mixture of brown rice and paddy obtained by de-air sorting to the discharge side Y of the receiving gutter 10, and 23 is a thrower that lifts the mixture of brown rice and paddy obtained by de-air sorting to the discharge side Y of the receiving gutter 9 and the wind sorting. This is a guide tube that communicates with the rear part of part B.

Therefore, if the partition plates 11 and 12 are kept in the state shown in FIG. 1, the mixture supplied from the thrower 22 through the receiving gutter 10 and into the sorting cylinder 8 from the drop port 15 will be directed from the supply side X to the discharge side Y. While flowing, the brown rice scooped up by the pot hole 7 is guided into the receiving gutter 9 by the partition plate 11, and some brown rice and some paddy are guided into the receiving gutter 10 by the partition plate 12. The paddy that is guided and not scooped up by the pot hole 7 moves inside the sorting barrel 8 to the discharge side Y. There, the brown rice guided into the receiving gutter 9 is sent to the discharge side Y, and is taken out after wind selection through the guide tube 23 to the rear of the wind selection section B. The brown rice guided into the receiving gutter 10 is sent to the supply side Y. Then, it enters the sorting cylinder 8 again through the drop port 15 and the sorting action is repeated.
The paddy transferred to the discharge side Y in the sorting barrel 8 is transferred to the grain frying blade 2
After being lifted up by the paddy tank 0 and discharged, it is returned to the paddy tank 1 through the reduction gutter 21 and released again.

Therefore, when the hulling operation is completed or the variety to be hulled changes and becomes a different variety, the mixture of brown rice and paddy remaining in the sorting barrel 8 is taken out. At this time, the partition plates 11 and 12 If they are tilted toward the receiving troughs 9 and 10, respectively, the back side will be on the upper side as shown in FIG. 4, and the upper portions of the receiving troughs 9 and 10 will be closed, respectively. Then, when the fluid remaining in the sorting barrel 8 is scooped up by the pot hole 7 and discharged, the parting plate 1
1 and 12 are received on the back surface, and then fall into the sorting cylinder 8 while being forcibly moved to the discharge side Y as they flow down by the inclined feed plates 16 and 17. By repeating this process, the remaining grains are quickly transferred to the discharge side Y, and
It is hoisted up and taken out.

The partition plates 11 and 12 are tilted toward the receiving troughs 9 and 10 to increase the rotational speed of the sorting cylinder 8 in conjunction with the blockage on the receiving troughs 9 and 10, thereby increasing the scooping action by the pot hole 7. You can.

In addition, as shown in FIG. 5, if the receiving troughs 9, 10 are provided with open/close valves 18, 19 which can be opened and closed at their bottoms, the remaining particles in the receiving troughs 9, 10 will also be removed from the sorting cylinder 8. Then, as mentioned above, it is taken out by the forced shifting action of the feed plates 16 and 17.

Further, although this embodiment has a configuration in which a plurality of receiving troughs are arranged in parallel, the gist of the present invention does not change even if a single receiving trough is used.

Effects of the invention In this way, the present invention is a rotary sorting huller consisting of a removal part, a wind sorting part, and a pot-and-hole type rotary sorting part, in which a rice-hulling machine is inserted horizontally into the sorting barrel that constitutes the pot-and-hole type rotary sorting part. A feed plate is provided on the back side of the partition plate whose lower edge is pivoted to the grain receiving side of the receiving gutter so that the inclination angle can be freely changed and adjusted, and a feed plate is provided which is inclined with the lower end on the discharge side, and the partition plate is placed on the receiving gutter side. Since the structure is such that it can be tilted to close off the top of the receiving gutter, the partition plate selects what is to be guided into the receiving gutter during hulling work, allowing for efficient sorting and removing grains remaining in the sorting barrel. When you want to take out the grains, you close the top of the receiving gutter by tilting it toward the receiving gutter side, and the feeding plate installed diagonally on the back receives the grains that are scooped up and released by the pot hole and is forced to the discharge side. The grains remaining in the sorting cylinder are quickly sent out to the discharge side.

This eliminates the need to lift and tilt the machine like in the past when removing residual grains, and simply tilts the partition plate toward the receiving gutter to block the upper part of the receiving gutter. The operation for removing the grains has become much simpler, and moreover, it has become possible to take out the grains quickly.
