Description

[Detailed description of the invention] (a) Industrial application field The present invention is equipped with a rice sorting device that separates incomplete grains such as rice cake from the raw rice supplied to the dehulling section in the pre-dehulling process. Regarding the huller that removes the perfect grains after incomplete grains are taken out by this rice sorting device, in particular, the incomplete grains such as rice grains taken out by this rice grain sorting device are passed through the wind sorting section. The purpose is to select grains with good fertility and take them out from the grain removal path of the wind-selecting section, so that taking out incomplete grains out of the machine does not become complicated.

(b) Prior art A conventional technology for a huller equipped with a sorting device for separating complete grains from incomplete grains is disclosed in, for example, Japanese Utility Model Application Publication No. 112479/1983 (hereinafter referred to as the former).
There is a device with the configuration shown in Figure 1. This is a device that sorts the grains that have been removed by hulling, before separating them into brown rice and paddy using the pot-hole type rotary sorting barrel that makes up the huller. The structure is such that incomplete grains are sorted out from the hulled grains, and at the same time, unhulled chaff is selected as much as possible and returned to the hulled hull.

In addition, in the method disclosed in Japanese Patent Application Laid-open No. 54-97253 (hereinafter referred to as the latter), a rice sorting device is installed in the process before hulling to separate complete grains and incomplete grains, and the selected complete grains are deprocessed. However, there is no particular description of the means for removing one of the incomplete grains that has been sorted out of the machine.

(c) Problems to be solved by the invention Therefore, the former method has problems such as reducing the shedding ability and inhibiting the shedding efficiency because all incomplete grains are also shedding, while the latter method The problem with the former can be solved by sorting out incomplete grains and only perfect grains before shedding, but it is necessary to extract those with high fertility from the incomplete grains. The configuration becomes complicated.

In view of these points, the present invention aims to improve the de-efficiency and de-efficiency while also extracting highly fertile grains from among the incomplete grains selected before de-degrading using a simple method. It was devised for the purpose of

(d) Means for solving the problem Therefore, in order to achieve the above-mentioned purpose, the present invention provides a paddy sorting device for separating complete grains and incomplete grains in the pre-process of dehulling. The complete grains that can be sorted out by the air selection part are removed, and the incomplete grains are dropped onto a part above the rice cake take-out path of the sorting air passage in the air sorting section, and are taken out of the machine from the rice grain take-out passage after wind selection.

(E) Effect With this structure, the raw paddy to be removed is sorted into complete grains and incomplete grains such as rice cake by the rice sorting device, and only the complete grains are removed and then processed after removal. is carried out to obtain brown rice,
At this time, incomplete grains that still remain among the complete grains that have been sorted by the rice sorting device are removed from the machine through the grain removal path of the wind sorting section.

In addition, the incomplete grains sorted by the paddy sorting device fall onto the upper part of the rice grain extraction path of the sorting air passage, where they are air-selected and relatively fertile grains are taken out from the rice grain extraction passage together. .

(f) Examples The present invention will be explained below with reference to the drawings of examples.

First, let's talk about the outline of the huller itself. A is the removal section, B is the wind sorting section, and C is the pothole type rotary sorting section. A rice huller is constructed by arranging part C.

The de-rolling section A is equipped with a paddy storage tank 1 and a pair of de-rolls 2, and at the front 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 rice husks is sucked out. The rice grains are discharged from the machine 4 to the outside of the machine, and the rice grains are taken out of the machine from the grain take-out passage 6 through the rice grain take-out passage 5 that communicates with the middle of the sorting air passage 3 to obtain a mixture of brown rice and paddy. The brown rice that is sorted from the mixture by the sorting section C is air-selected to remove small rice.

This pothole type rotary sorting section C has a receiving gutter 9 and a circulation gutter 10 inserted and horizontally suspended in a sorting cylinder 8 which has a large number of potholes 7 formed on its inner circumferential surface and is rotatably suspended horizontally. The mixture obtained at the front part of section B is transferred to the rear side by the circulation gutter 10 and dropped into the sorting cylinder 8, and while flowing inside the sorting cylinder 8 from the rear side to the front side, it is separated into brown rice and paddy. The brown rice to be sorted and sorted is air sorted at the rear of the wind sorting section B, and the paddy is evenly distributed on the inner circumferential surface of the sorting barrel 8 at the front end of the bucket 1.
1, the paddy is pumped up from a return gutter 12, passed through an inflow tube 13 into the bottom of the paddy storage tank 1, and then removed again by a derolling device 2.

In addition, 14 is a thrower that lifts the mixture of brown rice and paddy obtained at the front part of wind sorting section B to the front side of the circulation gutter 10.

Therefore, the complete paddy that has been sorted from the raw paddy by the paddy sorting device D, which will be described later, is supplied to a pair of de-rolls 2 and is then de-rolled. Brown rice is sequentially obtained from paddy using C.

Next, as the main part of the present invention, the paddy sorting device D and its related configuration and operation will be described.

This paddy sorting device D is installed in the paddy storage tank 1, and a large number of sorting holes 16 are formed on the circumferential surface of the paddy sorting device D, and the paddy sorting device 15 is rotatably mounted horizontally, and raw paddy is collected from the high entrance side X. It is a cylindrical body that separates what leaks from the sorting hole 16 and what does not by the flow toward the outlet side Y on the lower side and the stirring action. It is set in the direction.

The sorting hole 16 of this cylindrical body 15 is formed so narrow that incomplete grains such as rice cake pass through, but complete grains do not pass through.
7 and a support rod 20 having a square hole boss portion 19 on the exit side Y.
is loosely engaged with a support shaft 21 protruding toward the inlet side X, and the boss portion 19 is engaged with a drive shaft 22 of a motor M attached to the outlet side Y and rotating at a low speed.

Reference numeral 23 is a housing provided on the lower side of the cylinder 15 in which the sorting hole 16 is formed, and receives the complete grains flowing out from the outlet side Y end of the cylinder 15 inside the storage tank 1 and the incomplete grains leaking from the sorting hole 16, respectively. This is a receiving plate that divides the chambers 24 and 25.

Reference numeral 26 is a guide tube whose lower end opening 27 is inserted from the side above the sorting air passage 3 and whose upper end is communicated with the storage chamber 25 for receiving the incomplete grains. It is visible above the rice cake outlet 5 in No. 3.

Further, a storage chamber 24 for receiving complete grains in the paddy storage tank 1 is connected to the pair of unrolled rice 2,
The inflow tube 13 is also inserted into this storage chamber 24. 28 is a funnel for supplying raw rice to the entrance side X of the cylindrical body 15.

As a result, while the raw rice introduced into the funnel 28 flows into the cylinder 15 and flows toward the outlet side Y, incomplete grains such as rice cake leak out from the sorting hole 16 and enter the storage chamber 25. It is accepted and passes through the guide tube 26 to the sorting air path 3.
The complete grains that fall into the container and do not leak out from the sorting holes 16 flow out from the Y end on the exit side, are received in the storage chamber 24, are supplied to the derolling roll 2, and are removed.

This removed material and the above-mentioned guide tube 26 are passed through the sorting air passage 3.
The incomplete grains that fall to the top are both air-selected in the sorting air passage 3, and the incomplete grains from the guide tube 26 become relatively fertile grains that merge together and exit the machine from the grain outlet 6. It will be taken out.

In addition, at this time, the incomplete grains fall by the guide tube 26 to the upper part of the rice cake take-out path 5 of the sorting air path 3, so that they are properly air-selected without affecting the wind-selecting action of the removed particles. be.

(g) Effects of the invention As detailed above, the present invention includes a paddy sorting device that separates complete grains and incomplete grains in the preprocess of dehulling, and removes the perfect grains that can be sorted by this paddy sorting device. At the same time, the structure is such that the incomplete grains are dropped onto the upper part of the rice cake take-out path of the sorting air path in the wind sorting section, and are taken out of the machine from the grain take-out path after wind selection.
Raw paddy that is about to be removed is sorted into complete grains and incomplete grains by a rice sorting device, and the separated perfect grains are subjected to deprocessing, so that unnecessary incomplete grains are not removed, improving efficiency and deprocessing. While improving the efficiency, the sorted incomplete grains fall above the grain extraction path of the sorting air path, so they do not mix with the deflated grains of the complete grains and affect the wind separation effect of the deflated grains. Since the grains are wind-selected without being edible, incomplete grains can be easily recovered into relatively highly fertile grains, which has the advantage of being able to be used for suitable purposes other than food.
