Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to rice hulling plants and rice hulling equipment.
This invention relates to a sampling device that takes out a small amount of grain to check the degree of grain sorting after hulling.

(b) Prior art Conventionally, as a sampling device for a rice hulling device, there are methods such as those disclosed in Japanese Utility Model Application Publication No. 1987-76730 and Japanese Utility Model Application Publication No. 1982
The technology described in Japanese Patent No. 159739 was known to the public.

However, in Japanese Utility Model Application Publication No. 57-76730, the gutter 9 itself also serves as a check lid for the sampling port, so when the gutter 9 is pushed into the grain passage to take out the sample, the grains are exposed to the upper surface of the gutter 9. There was a problem with the grains falling down and scattering with great force.

Furthermore, in Utility Model Application No. 55-159739, the sampling port was located inside the case, and there was a problem in that the sampling grains could not be directly taken out of the aircraft. Another problem was that sampling grains could only be taken out intermittently, but not continuously.

In addition, as another technique for providing a sampling opening in the sorting part of the huller, there is
It was something like No. 150442.

However, conventional sampling devices require the user to insert a hand or other container into the sampling port to receive the grains. In addition, if the sampling port was always projected outward, a shutter had to be permanently installed.

(c) Problems to be solved by the invention The purpose of the invention is to make it possible to receive sampling grains directly outside the aircraft, and to avoid scattering of grains when receiving the sampling grains. Furthermore, when closed, the sampling port can be completely occluded.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained below.

Outlet side plate 8 of the sorting machine housed in the case 8
A is provided with a check lid 3 that can be rotated to open and close, and a protruding gutter 1 with an open bottom is fixed to the inner wall of the check lid 3, so that when the check lid 3 is closed, the grains are sent to the regular outlet 6. When the sample falls through the opening at the bottom of the extraction gutter 1 and the check lid 3 is opened, the extraction gutter 1 communicates with the sampling port 8b on the bottom surface of the check lid 3, and the extraction gutter 1
A sampling passage is formed between the check lid 3 and the outlet side plate 8a, and allows the grains to flow down to the outside of the outlet side plate 8a.

(e) Embodiments and operations The purpose and structure of the present invention are as described above.Next, the operation of the invention will be explained using the structure of the embodiment shown in the attached drawings.

FIG. 1 is a side sectional view of the sampling device of the present invention. Figure 2 is an overall front view of the side view of the rice huller. Figure 3 is also an overall side view. FIG. 4 is a perspective view of the check lid and the extraction gutter.

The outline of the rice hulling device will be explained with reference to FIGS. 2 and 3.

15 is a paddy elevator. The grain is fed into the hopper of this rice elevator, is fried, and the grain is removed from the huller head 16.
He is removed from school inside. The rice husks and mixed rice after dehulling are sorted by suction air from a suction fan 18 in a wind sorting section 17, and immature rice and the like are taken out from an immature rice outlet 21. The mixed rice of brown rice and paddy enters the mixed rice elevator 14 from the mixed rice conveyor 20, is fried, and is fed into the oscillating sorter 12. The oscillating sorter 12 separates brown rice, mixed rice, and paddy, and the paddy is transferred from the paddy conveyor 19 to the paddy elevator 15, and the mixed rice is transferred to the mixed rice conveyor 2.
0 through the flow board in the sorting chute 13.

Only brown rice is fed into the grain sorter in case 8. The grain sorter is composed of two rotary sieves 4, 4, and a clogging prevention rubber plate 9 is rotating at the upper center. Then, immature rice and broken rice among the brown rice put into the rotary sieves 4 and 4 fall through the mesh, and
It is collected by the conveyor 5 and collected in the trays 23 and 24. The fine grains that have not escaped through the mesh enter the brown rice elevator through the regular outlet 6.

The sampling device of the present invention is provided on the exit side side plate 8a of the case 8.

The configuration of the sampling device will be explained in detail with reference to FIGS. 1 and 4.

A sampling port 8b is opened in the outlet side plate 8a, and the check lid 3 is pivotably supported to open and close this opening. A U-shaped take-out gutter 1 is fixedly installed on the inner surface of the check lid 3, and is open at the top and bottom and whose inner end surface forms an arcuate grain surface.

Since the take-out gutter 1 is fixedly installed inside the check lid 3, it naturally rotates around the pivot point of the check lid 3, but a guide plate 2 is placed outside the rotation locus of the eject-out gutter 1 on the outlet side side plate 8a. is fixed to the inner surface of the The guide plate 2 is also a U-shaped metal fitting when viewed from above, and is configured to be slightly larger to fit around the outer periphery of the extraction gutter. 7 is a grain passage.

Explaining the effect.

When the check lid 3 is closed, the take-out gutter 1 is housed inside the case as shown in FIG. 4, and the bottom opening is open toward the grain passage 7 inside the case 8. Therefore, the fine grains that entered through the upper opening of the take-out gutter 1 also come out through the bottom opening. When the check lid 3 is disengaged and opened by turning the handle 10, the take-out gutter 1 also rotates and moves to the position indicated by the chain line in FIG. becomes the grain intake port, and the collected grains flow into the take-out gutter 1.
Since the opening at the bottom of the outlet side plate 8a is exposed to the outside of the outlet side plate 8a, the grains for sampling are taken out from here to the outside of the outlet side plate.

Although this embodiment has been described with respect to a brown rice sorter, it goes without saying that it can also be implemented in a mixed rice or paddy sorter.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, when the check lid itself doubles as the extraction gutter as in the conventional technology, when the check lid is inserted into the grain passage, the sampled grains fall and scatter with force. In the case of the present invention, a separate take-out gutter 1 is provided inside the check lid 3, so the grains scattered in the take-out gutter 1 hit the inside of the check lid 3, so this part prevents the grains from scattering. It is possible.

Second, since the check lid 3 and the take-out gutter 1 are provided separately, the sampling port 8b can be completely closed by the check lid 3 and the take-out gutter 1, so that the sample can be used as both the take-out gutter and the check lid, as in the past. This eliminates the problem of scattered grains flying out from the open bottom of the take-out gutter, which was the case when the take-out gutter was used.
