A horizontal opening / closing shutter 20 is provided on the vertical supply cylinder 6 below the supply hopper 7. The horizontal opening / closing shutter 20 moves horizontally with respect to the vertical supply cylinder 6 to open and close the vertical supply path 54 of the vertical supply cylinder 6. The horizontal opening / closing shutter 20 is provided with a collapsing projection 32 reaching the grain area in the supply hopper 7.

The collapsing projection 32 is different from the horizontal opening / closing shutter 20,
It can be replaced by bolt 33 (or pin). Collapsing protrusion
If 32 is integrated with the horizontal opening / closing shutter 20, when the horizontal opening / closing shutter 20 is inserted into the vertical supply tube 6, a window through which the collapsing projection 32 passes must be formed in the vertical supply tube 6, and the window must be opened. If formed, there is a risk that the grain will leak. Therefore, the collapsible projection 32 is mounted in a state where the horizontal opening / closing shutter 20 is inserted into the vertical supply cylinder 6. Collapsing projection 32
Is provided at the front side of the supply passage 54 when the horizontal opening / closing shutter 20 is in a closed state so as not to prevent the opening operation of the horizontal opening / closing shutter 20. When the horizontal opening / closing shutter 20 is a member having a considerable thickness, it is preferable to engrave a screw on the horizontal opening / closing shutter 20 itself, remove the supply hopper 7, and screw it from above. When the horizontal opening / closing shutter 20 is fully pulled, the collapsing projection 32 collides with the inner surface of the vertical supply cylinder 6 or the inner surface of the supply hopper 7 to give an impact, and the impact also causes the lump of grain to be disintegrated. Since the collapsing projection 32 is for collapsing the grain mass on the horizontal opening / closing shutter 20, the collapsing projection 32 needs to have a length that meets the above purpose.

55 is a fixed nut.

(Operation) Next, the operation will be described.

Normally, brown rice is charged into the supply hopper 7, the horizontal opening / closing shutter 20 is moved horizontally, and the supply path 54 in the vertical supply cylinder 6 is moved.
When opened, brown rice flows down from the supply hopper 7 into the vertical supply cylinder 6, flows down on the on-off valves 8 and 9 and flows into the vertical cylindrical refined shell chamber 74, and in this state, the vertical grain refined roll 57 When the rice is rotated, the brown rice supplied to the vertical cylindrical sperm chamber 74 is agitated and milled, and the peeled bran is ejected to the outside through the eyes of the polishing cylinder 46 and then sucked by the bran suction blades 64 to the outside. Is released to.

In the polishing process, a load is generated in the vertical cylindrical sterilization chamber 74, so that the whitening cylinder 46 rotates against the elasticity of the spring 53 due to the load, and the rod 52 that has been inclined up to that time is made vertical. , The lower support frame 56 descends together with the white polishing cylinder 46 to widen the lower gap,
The polished rice is dropped on the scraping body 64 and discharged.

Then, the grain in the supply hopper 7 flows down the passage that gradually becomes smaller until it reaches the horizontal opening / closing shutter 20, so that the grain causes a bridge phenomenon on the horizontal opening / closing shutter 20, and as shown in FIG. Therefore, although it may not fall even if the horizontal opening / closing shutter 20 is opened / closed, the present invention relates to the opening operation of the horizontal opening / closing shutter 20 to collapse the grain layer mass above the horizontal opening / closing shutter 20. Since the projection 32 for projecting is provided so as to project into the grain layer area above the horizontal opening / closing shutter 20, when the horizontal opening / closing shutter 20 is opened, the grain layer is stirred by the collapsing projection 32, so the bridge is collapsed, Make sure it falls. In addition, since the collapsing projection 32 has a separate structure from the horizontal opening / closing shutter 20, it can be attached without forming a window in the vertical supply cylinder 6, and when the horizontal opening / closing shutter 20 is pulled to the full extent, it collapses. Since the projecting projection 32 collides with the inner wall of the vertical supply cylinder 6 or the inner wall of the supply hopper 7, the impact destroys the bridge.

(Effect) The known one described in Japanese Utility Model Publication No. 15-23145 has a configuration in which, besides the horizontal opening / closing shutter provided in the supply hopper, a device capable of stirring the paddy in the hopper is provided. Therefore, it cannot be installed on existing equipment. In addition, since the awns attached to the paddy are removed, the awns must be rotated all the time. In addition, registered utility model No. 22144
The device disclosed in Japanese Patent Laid-Open Publication No. 2003-242242 also has a structure in which, in addition to the horizontal opening / closing shutter provided in the supply hopper, a device that can stir the paddy in the hopper is provided, and therefore it cannot be installed in an existing device. It also removes the straw that is present in the paddy, so it must be rotated all the time.

In addition to the problem of the presence of the awns and the clogging caused by straw chips, there is a problem of the bridge phenomenon shown in FIG. The grain E at the bottom of the supply hopper B is clogged in a bridge shape to form a grain lump, and even if the horizontal opening / closing shutter D is opened as shown in FIG. 7, it does not flow down.

However, according to the present invention, the supply hopper 7 is connected to the upper part of the vertical supply cylinder 6 connected to the upper part of the vertical cylindrical aseptic chamber 74, and the supply hopper 7 or the vertical supply cylinder 6 is moved horizontally. Supply route
In the case where a horizontal opening / closing shutter 20 for opening / closing 54 is provided, the horizontal opening / closing shutter 20 is
Is moved in the opening direction to collapse the grain bed mass on the upper part of the shutter 20 and, at the end, the hopper 7 or the feed cylinder 6
A collapsing projection 32 is provided so as to project into the grain layer area to collide with the inner wall of the shutter and give an impulse.
It is a separate structure from 20 and is configured to be attached to the shutter 20, and the projection 32 is a grain supply device in the grain refiner provided on the front side when the shutter 20 is closed. Therefore, when the shutter 20 is opened, the bridge can be collapsed by the collapse projection 32.

(B) Since the collapsing projection 32 is a separate item and attached later, an existing one can also be attached.

C. Since the collapsing projection 32 is attached later as a separate item, it is not necessary to form a through hole in the supply hopper 7 or the vertical supply cylinder 6 for attaching the collapsing projection 32. When the through hole for attaching the collapsing projection 32 is formed, when the shutter 20 is opened, the collapsing projection 32 does not collide with the supply hopper 7 or the inner wall of the vertical supply cylinder 6, so that the collapsing projection 32 is supplied. It becomes impossible to give impulse by colliding with 7 or the inner wall of the vertical supply cylinder 6. In the present invention, since the collapsing projection 32 collides with the inner wall of the vertical supply cylinder 6 or the supply hopper 7,
The impact destroys the bridge.

Has the effect.
