Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applied to an integrated hulling device used as a small rice center or shared hulling device, in which the falling mixed rice is transported to the mixed rice conveyor. This relates to the structure of the grain board that allows the grain to bounce up and be discharged outside the machine on the exhaust wind.

(b) Prior Art Conventionally, in a hulling device or a sorting device, a technique of providing a cover to prevent scattering over the grain board has been known. For example, Jikko Sho 33-
Publication No. 138, Publication No. 35-3251, Publication No. 3251, Publication No.
This is similar to the technique described in Publication No. 38-4972.

(c) Problems that the invention aims to solve In the conventional integrated rice huller sorting method, the mixed rice that has been dehulled with rubber rolls and the mixed rice that is returned from the swinging sorter naturally flows into the mixed rice conveyor. Because of the structure, no device such as a cover was provided above the mixed rice conveyor.

Therefore, as shown in Figure 4, the rice that has fallen from the dehulling rolls and hits the mixed rice conveyor more forcefully than the grain plate, and the mixed rice that is returned from the oscillating sorting device are near the top of the mixed rice conveyor. The particles that hit the rice mixer directly will be blown up to the upper right by the rotation of the mixed rice conveyor, carried by the exhaust air from the suction fan, and carried directly to the dust removal duct, where they will be discharged outside the machine. It was hot too.

However, by rotating the mixed rice conveyor in the opposite direction, it is possible to reduce the amount of mixed rice that jumps up to the upper right on the mixed rice conveyor. In order to rotate in the same direction, gears, etc. are required to rotate only the mixed rice conveyor in the opposite direction.
This results in high costs.

(d) Means for solving the problem In order to solve the above problems, the present invention is constructed as follows.

A hulling device head 3, a first flow grain plate 15 below it, and a mixed rice conveyor 19 below it are arranged in the center,
A suction fan 18 for suctioning and discharging the rice grains falling from the hulling device head 3 is arranged on one side, and a mixed rice conveyor 19 is arranged on the other side for discharging the mixed rice from the swing sorting device 23.
In a configuration in which a mixed rice flow grain board 17 is arranged to guide the mixed rice grains, and the rotation direction of the mixed rice conveyor 19 is such that the rotation direction of the upper surface of the conveyor is along the suction wind of the suction fan 18, the mixed rice grains are Mixed rice grain board on the rice grain board 17 side and the first grain board 1
A chevron-shaped scattering preventing flowing grain plate 16 made up of a mixed rice flowing grain plate on the 5 side is provided, and the scattering preventing flowing grain plate 16 has a shape whose apex is inclined to the mixed rice flowing grain plate 17, and the mixed rice flowing grain plate 17 and the scattering prevention flow grain plate 16 is configured to be smaller than the distance between the first flow grain plate 15 and the scattering prevention flow grain plate 16 at the lower part of the hulling device head 3.

(E) Embodiment The purpose of the present invention is as described above, and the structure of the embodiment shown in the attached drawings will be explained.

FIG. 1 is a front view of the entire hulling device, FIG. 2 is an enlarged front view of the suction wind sorter, FIG. 3 is an enlarged front view of the mixed rice conveyor, and FIG. 4 is a front view of the conventional rice washing machine.

To explain the overall configuration in FIG. 1, a hopper is provided below the paddy elevator 1, and paddy is thrown into the hopper using a chute, a paddy bag, or the like.
This paddy is lifted into a paddy tank 2 by an elevator 1 and stored. A hulling device head 3 consisting of a pair of dehulling rolls 4 is disposed below the paddy tank 2, and the paddy grains falling from the paddy tank 2 are dehulled by the dehulling rolls 4. A suction wind sorting section is provided below, and the mixed rice and paddy grains are wind sorted in the falling suction wind sorting section.

That is, the grains are first scattered by the reflector 11 and fall onto the flow boards 12, 13, 14, the first flow grain board 15, and the mixed rice conveyor 19, and during the falling process, the mixed rice is discharged by the suction fan 18. falls, and the rice grains are blown into the dust exhaust duct 5 and discharged.

On the other hand, relatively light immature rice is taken out to the front of the machine by the second conveyor 6, mixed rice consisting of brown rice and paddy is transported to the rear by the mixed rice conveyor 19, and is lifted by the mixed rice elevator 20 and mixed. It is stored in rice tank 21. From the mixed rice tank 21, rice is gradually poured into a hopper 22 located below, and from the hopper 22, it is fed into a swing sorting device 23.

The oscillating sorting device 23 has several sorting plates arranged above and below,
While the rice is oscillated, the mixed rice flows from the rear to the front, and is sorted into brown rice, paddy, and mixed rice by frictional resistance. The paddy is conveyed rearward by the paddy conveyor 8 from the right chamber 7R via the grain board, and then sent to the paddy tank 2 from the paddy elevator 1 again.

The mixed rice reaches the mixed rice conveyor 19 from the middle chamber 7M through the mixed rice flow grain plate 17, and then reaches the mixed rice conveyor 19.
The mixed rice is conveyed backwards and returned to the mixed rice elevator 20.
Shutters 24 and 25 are switching shutters for taking out the shutters to the outside from chutes 26 and 27. Further, the shutter 30 is used to return the hulled grains since the hulling and sorting have not been sufficiently carried out at the initial stage of the hulling operation.

Next, the brown rice falls from the left chamber 7L onto rotary sorting sieves 28 and 29 for grain sorting, and the fine grains are finally taken out from the rear.

In this overall configuration, the scattering prevention flow grain plate 16 of the present invention has a mountain shape when viewed from the front, with the apex tilted to the left, as shown in FIGS. 2 and 3. It is in the air path of suction wind from
Moreover, it is arranged at the upper part of the mixed rice conveyor 19.
The interval between the mixed rice flow grain plate 17 and the scattering prevention flow grain plate 16 on the left side is configured to be smaller than the interval between the first flow grain plate 15 and the scattering prevention flow grain plate 16 on the right side.

(f) Effects By having the structure as described above, the present invention operates as follows.

That is, the mixed rice that has been dehulled by the dehulling rolls 4 and the mixed rice that has returned from the shaking sorting device flows to the mixed rice conveyor 19, but the scattering prevention grain board 16 of the present invention is As shown in Figure 3, the mixed rice is prevented from directly hitting the mixed rice conveyor 19.
Furthermore, even if the grains hit directly through the gap, they are configured so that they bounce off the back side of the anti-scattering flow plate 16 or bounce off the side plate of the mixed rice conveyor 19. In other words, the mixed rice that bounces upward due to the rotational force of the mixed rice conveyor is eliminated.

(G) Effects of the invention Due to the above-described structure and operation, the present invention has the following effects.

First, it has become possible to construct an inexpensive shatterproof flow grain plate with a simple structure without changing the rotation direction of the mixed rice conveyor.

Second, all of the mixed rice that falls from the de-wall rolls 4 and the swing sorting device 23 to the mixed rice conveyor 19 no longer bounces upwards, and is no longer discharged out of the machine on the exhaust wind. It was. As a result, the recovery rate of polished rice has increased, and brown rice can now be obtained efficiently.
