(Refer to Japanese Patent Publication No. 36-1118).

(Problems to be Solved by the Invention) The known circulation rice mill is a horizontal circulation rice mill,
The pressure for circulating milling was controlled by adjusting the pressure in the pressure chamber at the tip of the horizontal grain feeding spiral by adjusting the resistance valve. However, since there is no stirring in the pressure chamber, its effectiveness could not be expected.

(Means for Solving the Problem) Therefore, the present invention provides a vertically rotating downward feeding grain spiral 5 and a vertically rotating polishing roll 6 in the center of the circulation tank 8, and The outer periphery of the spiral 5 is surrounded by a grain feeding tube 12 to form a grain feeding chamber 11, and the outer periphery of the vertically rotating whitening roll 6 is surrounded by a bran removing tube 20 to form a rice polishing chamber 21, A vertical adjustment body 50 is attached to the lower end of the grain feeding tube 12, and an inlet 15 for flowing into the grain feeding chamber 11 is provided at the upper end of the grain feeding cylinder 12, and an outlet 45 for flowing out from the rice milling chamber 21 is provided between the vertical adjustment bodies. A vertical adjuster 50 is provided above the inlet 15 to adjust the size of the inlet 15 by moving up and down.
The lever rod 40 and the weight 44 are arranged so that when the 0 is moved up and down, the amount is changed by 1g1ta, and the bran removal cylinder, the vertical adjustment cylinder 32, and the vertical sliding grain feeding cylinder 17 are moved down integrally.
This is a vertical circulation rice milling machine in which the vertically sliding grain feeding cylinder 17 and the vertically adjusting body 50 are connected by a link mechanism.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. L is a lower case, and a motor 2 is fixed in the lower case 1 in the F direction. 3 is the upper wall of the lower case l to which the motor 2 is attached. A rotating shaft 4 of the motor 2 extends vertically upward through the one-part wall 3, and a downward feeding grain spiral 5 and a milling roll 6 are attached to the outer peripheral surface of the rotating shaft 4. Reference numeral 7 denotes a stirring protrusion fixed to the outer periphery of the whitening roll 6. A circulation tank 8 is attached above the lower case 1.

The rotating shaft 4 is located at the center of the circulation tank 8, and its upper end 9 is formed lower than the upper edge 10 of the circulation tank 8 so that rice grains can circulate inside the circulation tank 8. The outer periphery of the downward grain feeding spiral 5 is surrounded by a concentric grain feeding tube 12 so as to form a grain feeding chamber 11. The upper end 13 of the grain feeding tube η faces near the upper end 9 of the rotating shaft 4, and forms a hopper part 14 that gradually becomes wider as it goes upward from the upper end 13. An inlet 15 is formed between the outer circumference of the upper end 9 and the inner circumference of the upper end 13. The lower end 16 of the grain feeding barrel is located at an intermediate position in the vertical direction of the downward grain feeding spiral 5, and the area below the lower end 16 is surrounded by a vertically sliding grain feeding barrel 17. The upper end 18 of the vertically sliding grain feeding cylinder 17 is fitted to the outside of the lower end 16 of the grain feeding cylinder 12 so as to be able to slide up and down, so that even if the vertically sliding grain feeding cylinder 17 moves down to the maximum, it will not move further than the lower end 16. It is formed so that it does not come off.

The lower end 19 of the vertical sliding grain feeding cylinder 17 faces the lower end of the downward feeding grain spiral 5, but since the vertical sliding grain feeding cylinder 17 itself moves up and down, the lower end 19 is the lower end of the downward feeding grain spiral 5. It has a structure that slides up and down centering on. The upper end of the bran removal tube is connected to the lower end 19. A whitening chamber 21 is formed between the outer peripheral surface of the whitening roll 6 and the inner surface of the bran removing tube. The lower end η of the whitening roll 6 is formed with a tapered portion 23 whose diameter gradually becomes smaller toward the bottom. δ is set in series,
A horizontal rotary disk bottom plate is fixed to the lower end of the large diameter portion δ. The horizontal rotating disk bottom plate has a structure that rotates as the rotating shaft 4 rotates, and guides the rice grains that have fallen onto the horizontal rotating disk bottom plate 26 in all directions. A bran suction fan is attached to the lower part of the horizontal rotating disc bottom plate.1. It is surrounded by a case 28 of a bran suction fan n, a part of which is opened, and a bran box (9) is attached to the outside thereof.

The lower end 31 of the bran removal cylinder 20 reaches a position slightly lower than the tapered portion 23, and the upper end of the vertical adjustment cylinder is fixed to the lower end 31. The vertical adjustment barrel has a funnel portion formed at its upper end, the diameter of which gradually decreases toward the bottom. The funnel part n faces the taper part B. A reverse funnel part 34 whose diameter gradually increases is formed at the lower end of the funnel part 33, and a vertical hanging part 35 is formed at the lower end of the reverse funnel part.

will be established. A fixed cylinder g is provided inside the vertical hanging part, and the fixed cylinder is fixed to the circulation tank 8 via a support rod.A lever rod 40 is formed at the outer end 39 of the connecting rod. The elongated hole 41 is engaged.The outer end of the lever rod 40 is connected to the shaft 4.

A support rod 43 is connected to the outer side of the support rod 43, and a weight 4 is attached to the support rod 43.
4 is installed in an adjustable manner.

When rice grains are pushed into the milling chamber 21 by the action of the downward feeding spiral 5, the pressure within the milling chamber 21 increases, and the funnel portion 33 tends to descend under the pressure. This descending force and the weight of the weight 44 are balanced to set the funnel wing at a desired position, and adjust the size of the flow path 45 formed between the funnel part 33 and the tapered part A. Even if the lower end 46 of the vertical hanging part is raised to the maximum, the upper end 4 of the fixed cylinder g
Make sure it does not go beyond 7. A horizontal bar 48 is attached above the center of the circulation tank 8, and a hanging guide rod 49 is attached to the center of the horizontal bar 48. A vertical adjustment body 50 is attached to the hanging guide rod 49 so as to be vertically slidable. The vertical adjustment body 50 is formed in a cylindrical shape, and when the lower end 51 of the vertical adjustment body 50 descends, it approaches the hopper part 14 and closes the inlet 15.
narrow. 52 is a sliding tube attached to the center of the vertical adjustment body 50, and is fitted to the hanging guide rod 49. A protrusion is provided on the side of the sliding tube 52, and a long hole formed at the tip of the vertical movement lever is fitted into the protrusion.

The base of the vertically movable rod 54 is pivotally attached to the circulation tank 8 side by a shaft 56, and the vertically movable rod has a long hole 55 that moves vertically around the contour. The L end between the upper and lower rods is attached to the middle part of the vertical moving rod by a shaft 57, and the upper end of the upper screw 59 is screwed into the lower end of the upper rod 58. A lower rod 60 is provided, the lower end of the lower rod 50 is rotatably attached to the upper end 18 of the vertically sliding grain feeding cylinder 17 with a shaft 61, the lower part of the lower screw head is screwed into the upper part of the lower rod 60, and the upper screw 59 and the lower screw 62 are screwed together by a turnbuckle.

That is, when the turnbuckle 8 is rotated, the shaft 57 and the shaft 61
The distance between the two is adjusted.

In addition, 64 is a rice bran chamber, and 65 is a circulation ascending path.

(effect) Next, we will discuss the effect.

(When the weight 44 is set inward) When the weight 44 is adjusted to the innermost position, the elongated hole 41 of the lever lever
Therefore, the vertical sliding grain feeding cylinder 17, the bran removal cylinder holder, and the vertical adjustment cylinder 32 are all lowered, and the outflow port formed between the taper part n and the funnel part 33 is lowered. 45 is opened to the maximum, lowering the lower rod 60 which is pivotally attached to the upper end 18 of the vertically sliding grain feeding cylinder 17 with a shaft 61, and lowering the lower screw, the turnbuckle 63, the upper screw 59, and the upper rod 58.
, the elongated hole 5 of the vertically movable rod 54 is lowered to the maximum via the shaft 57, thus the lower end 5 between the vertically adjusting bodies! is closest to the hopper portion 14 and narrows the inlet 15 to the maximum extent.

That is, the inlet 15 is adjusted to be narrow and the outlet 45 is adjusted to be wide.

In this state, brown rice is put into the circulation tank 8, and when the motor 2 is energized and the rotating shaft 4 is rotated, the downward feeding grain feeding spiral 5 fixed to the outer periphery of the rotating shaft 4 and the milling roll 6 are removed.
rotate together, and a small amount of grain that flows in from inlet 1 5 is
The brown rice filling the grain feeding chamber 11 is sent downward through the grain feeding spiral 5.
It is sent downward by the rotation of the milling chamber 21, and the brown rice that is filling the whitening chamber 21 is sent further into the whitening chamber? Try to slightly increase the pressure inside i. When the whitening roll 6 rotates in this state, the rice grains are stirred by the stirring protrusions 7 formed on the outer periphery of the whitening roll 6, and the rice bran on the surface of the rice grains is peeled off and released from the rice bran removal tube J into the rice bran chamber mixture, and then downward. The rice bran is suctioned by the rotation of the rice bran suction fan n and stored in the rice bran box 30.

Therefore, the downward feeding grain spiral 5 continues to rotate and feeds the grains one after another into the milling chamber 21, so that the grains are polished in the milling chamber 21, descend through the outlet 45, and pass through the ascending path δ. The blood circulates through the air, creating circulation. The grain thus rises between the ascending paths and flows into the feeding chamber 11 through the inlet 15, but as mentioned above, the vertical adjustment body 50 is lowered, and there is a narrow gap between the hopper part 14 and the lower end 51. Since it is open, the amount flowing into the grain feeding chamber 11 is small, and therefore the pressure inside the milling chamber 21 is low, allowing low-pressure milling.

(When the weight 44 is adjusted outward) When the weight 44 is adjusted to the outermost position, the elongated hole 4 of the lever rod 40
1 becomes maximum, and therefore, the vertical sliding grain feeding cylinder 17, the bran removing cylinder 32, and the vertical adjustment m cylinder 32 all rise,
The outlet 45 formed between the taper part n and the funnel part 0 is closed to the minimum, and the lower rod 60, which is pivotally attached to the upper end 18 of the vertically sliding grain feeding cylinder 17 by a shaft 61, is moved upward, and the lower part is opened. screw 6
2. Turnbuckle 63, upper screw 59. Upper rod 5
8. Raise the elongated hole 55 of the vertical moving rod 54 to the maximum via the shaft 57, therefore, the lower end 51 of the -E lower adjustment body 50
The inlet is maximally spaced in the hopper part 14! 5 to the maximum width.

That is, the inlet 15 is adjusted to be wide and the outlet 45 is adjusted to be narrow.

In this state, brown rice is put into the circulation tank 8, and when the motor 2 is energized and the rotating shaft 4 is rotated, the downward feeding grain feeding spiral 5 fixed to the outer periphery of the rotating shaft 4 and the milling roll 6 are removed.
rotate together, and a large amount of grain that flows in from the inlet 15 is
The brown rice filling the grain feeding chamber 11 is sent downward through the grain feeding spiral 5.
The rice is sent downward by the rotation of , and the pressure inside the whitening chamber 21 is further strongly increased against the brown rice group filling the inside of the whitening chamber 21. When the whitening roll 6 rotates in this state, the rice grains are stirred by the stirring protrusions 7 formed on the outer periphery of the whitening roll 6, and the rice bran on the surface of the rice grains is peeled off by the strong pressure polishing action and transferred from the rice bran removal tube to the rice bran chamber. The rice bran is discharged, sucked in by the rotation of the lower monocular fan 27, and stored in the rice bran box 30.

Thus, the downward feeding grain spiral 5 continues to rotate and feed grains into the milling chamber 21 one after another, so that the grains are polished in the milling chamber 21 and descend through the outlet 45 to increase the circulating price. It circulates through the body, creating circulation. The grain then descends through the circulation ascending path 6 and flows into the grain feeding chamber 11 through the inlet 15, but as mentioned above, the space between the upper and lower adjustment bodies is raised, and between the hopper part 14 and the lower end 51. Since it is wide open, a large amount of grain flows into the grain feeding room 11, and therefore,
The pressure inside the whitening chamber 21 is high and strong pressure can be squeezed.

(Effects) As mentioned above, the conventional circulation type rice mill has a horizontal grain feeding spiral installed horizontally in the circulation tank, a bran removing cylinder is installed at the bottom of the horizontal grain feeding spiral, and A resistance valve is attached to the pressure chamber at the tip so that the rice can be circulated in the direction of the arrow to remove bran and perform circulatory polishing (see Japanese Patent Publication No. 36-1118). The known circulation rice milling machine is a horizontal circulation rice milling machine, and the pressure for circulating milling is controlled by a resistance valve to adjust the pressure in the pressure chamber at the tip of the horizontal grain feeding spiral. there were. However, since there is no stirring in the pressure chamber, its effectiveness could not be expected.

However, in the present invention, a vertically rotating downward feeding grain spiral 5 and a vertically rotating milling roll 6 are provided in the center of the circulation tank 8, and the outer periphery of the downward feeding grain spiral 5 is a grain feeding tube. The outer periphery of the vertically rotating whitening roll 6 is surrounded by a rice bran removing barrel to form a rice milling chamber 21, and the lower end of the bran removing barrel is provided with an upper and lower adjustment body. An inlet 15 for flowing into the grain feeding chamber 11 is attached to the upper end portion of the grain feeding cylinder.
Outflow ports 45 flowing out from the rice polishing chamber 21 are formed inside the upper and lower 31 joint bodies 50, and a vertical adjustment body 50 is provided above the inflow port 15 to adjust the size of the inflow port 15 by moving up and down. , the outlet 45 is located above and below? A cylinder body 50
is adjusted in size when L is moved downward, and the lever lever and the weight are adjusted so that the bran removal tube silver, the vertical adjustment tube jig, and the vertical sliding grain feeding tube 17 move up and down integrally. Since it is a vertical circulation type rice milling machine in which the vertically sliding grain feeding cylinder 17 and the vertically adjusting body 50 are connected by a link mechanism, it is possible to make desired adjustments by only adjusting the weight 44. has. In addition, since the bran removing barrel can be moved up and down by adjusting the lever 40, adhering bran can be cleaned, and since the structure is also used, assembly is easy.
