Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing an embodiment of the present invention.
Reference numeral 1 denotes a housing having a shape such as a rectangular tube or a cylinder, and a base 2 is attached to the upper surface of the housing 1. A motor 4 that rotates the upper die 3 at a slow rotational speed (about the rotational speed of a normal stone mill) is built in the housing 1. The rotational force of the motor 4 is linked to a rotational drive body 4b having a gear 4c accommodated in the central portion of the housing 1 via a chain belt 4a.

Reference numeral 5 denotes a cylindrical powder receiving container attached by drilling a large hole in the center of the base 1a. A through hole 5a is formed in the center of the cylindrical powder receiving container 5. The rotary shaft 4d is loosely fitted in the through-hole 5a, the base of the rotary shaft 4d is fixed to the upper center of the rotary drive body 4b in the vertical direction, and the head 4e of the rotary shaft 4d is the through-hole of the lower die 6 It protrudes from 6b and fits into a recess 3a formed at the center of the back surface of the upper die 3, the driving force of the rotating shaft 4d is transmitted to the upper die 3, the lower die 6 is fixed, and the back surface of the upper die 3 is the lower die It rotates while being rubbed against the upper surface of 6.

The upper surface of the lower mortar 6 is slightly higher at the top and inclined lower toward the peripheral edge, and a groove 6 a is formed on the upper surface of the lower mortar 6. Reference numeral 6b denotes a through hole 6b drilled in the center of the lower die 6, and the rotating shaft 4d is inserted into the through hole 6b in a loose fit. In consideration of the fact that the lower mill 6 is a table-top electric mill, it has been described that the thickness of the lower mill 6 is, for example, less than half that of the upper mill 3, but this is not necessarily the case. The thickness is not limited to the above, and may be any thickness as long as it is portable. However, it is desirable that the upper die 3 is thicker and heavier than the lower die 6 to finish the grain into a fine powder with a stone mill.

The upper mill 3 has the same outer diameter as the lower mill 6 but is formed thicker than the lower mill 6 to ensure a certain weight. When the upper mill 3 itself has a constant weight, the grain grinding condition at the contact surface between the lower mill 6 and the upper mill 3 is improved, and a fine powder can be obtained. Reference numeral 3b denotes a brush made of a plate-like piece attached to the lower part of the outer peripheral wall of the upper die 3, and in this example, the brush-like brush may be used. The brush 3b is flour stored in a groove formed by the outer peripheral surface of the lower mill 6, the inner peripheral surface of the cylindrical powder receiving container 5, and the inner bottom surface of the cylindrical powder receiving container 5 surrounded by both inner and outer peripheral surfaces. It will fall from the flour take-out hole 5b formed at the appropriate position of the groove. 3c is a grain supply hole which penetrates in the vertical direction at a position (eccentric position) shifted from the center of the upper mill 3. The size of the grain supply hole 3c may be a size that can drop smoothly without being caught halfway when an appropriate amount of grain is supplied.

A grain adjusting hopper 7 is attached to the upper surface of the upper mill 3 and is fixedly attached to a position communicating with the upper part of the grain supply hole 3c. Therefore, the grain adjusting hopper 7 rotates in conjunction with the upper mill 3. The size of the grain adjusting hopper 7 may be any size as long as it can store one or several times a suitable amount of grains. The upper part of the grain adjusting hopper 7 is wide and the lower part is gradually narrowed so as to have the same size as the grain supply hole 3c. Reference numeral 8 denotes an upright bar constituting an engaging member attached so as to protrude above the grain adjusting hopper 7.

9 is a grain hopper. As the upper mill 3 rotates, the grain supply hole 3c also rotates while drawing a concentric circle on the upper mill 3, and the lower opening of the grain hopper 9 coincides with a predetermined position above the concentric circle drawn by the grain supply hole 3c. To be installed. The grain hopper 9 includes a vertical upright portion 10a fixedly attached to the side wall of the housing 1, and a horizontal support portion 10b formed in a horizontal direction from the upper end of the upright portion 10a toward the center of the table 2. It is attached to the arm 10. The upper part of the grain hopper 9 is open to a wide mouth, and the lower part forms an opening that substantially coincides with a hole 10c that is slightly smaller than the inner diameter of the grain supply cylinder 11.

Reference numeral 11 denotes a shutter housing cylinder that houses the rotary shutter 12, and is fixed so as to hang from the periphery of the hole 10c on the back surface of the horizontal support portion 10b. One or a plurality of shutter openings 11a are formed at predetermined locations on the side wall of the shutter housing cylinder 11. In the case of this example, the case of one opening 11a is shown. When a plurality of openings 11a are formed, the grain can be supplied a plurality of times by one rotation of the upper mill 3. The rotary shutter 12 is housed so that its outer peripheral surface is in sliding contact with the inner wall of the shutter housing cylinder 11, and the inner wall surface of the rotary shutter 12 is flush with the inner wall of the hole 10c and the inner wall of the lower opening 9a. In addition, the inner wall near the upper end of the rotary shutter 12 has a curved tapered surface so that grains can easily fall off. An opening 12a having a size corresponding to the shutter opening 11a is formed at a predetermined position on the outer peripheral wall of the rotary shutter 12. Inside the rotary shutter 12, a slide 12b that is linearly inclined toward the lower part of the opening 12a is provided. FIG. 4 shows that the slide 12b is formed in a flat rectangular shape so that the grain can be smoothly lowered without staying on both sides of the slide 12b. Let you supply the exact amount of grain.

Reference numeral 13 denotes a shaft rod that passes through the center of the slide 12b and extends in the vertical direction, and a screw is engraved on the outer peripheral surface. The shaft 13 penetrates through the grain supply cylinder 11 and the grain hopper 9 so that the height can be adjusted in the vertical direction, and penetrates through the support plate 14 provided at the upper end of the grain hopper 9. 14 is screwed by a nut 15 or the like. Therefore, the shaft 13 can be moved up and down by adjusting the nut 15 or the like, and the opening area when the shutter opening 11a of the shutter accommodating cylinder 11 and the opening 12a of the rotary shutter 12 overlap can be appropriately changed. It is possible to supply an appropriate amount of grain accurately and reliably.

As shown in FIG. 4, the rotary shutter 12 is formed so that the slide 12 b formed in the cylindrical body has a width corresponding to the opening width of the shutter opening 11 a provided on the side wall of the shutter accommodating cylindrical body 11. By filling the internal space and making the slide surface 12b of a rectangular inclined surface, there is no play space inside the rotary shutter 12, so that grains do not stay or get caught in the play space, and smoothly slide down the slide table 12b. It becomes.

Reference numeral 16 denotes a horizontal bar that constitutes an engaging member attached to a shaft bar 13 positioned below the rotary shutter 12. When the upright bar 8 that protrudes above the grain adjustment hopper 9 also rotates on the concentric circle on the upper die 3 when the upper die 3 rotates, the upright bar 8 is always in contact with the horizontal bar 16. Thus, the rotary shutter 12 is rotated, and the shutter opening portion 11a and the opening portion 12a of the rotary shutter 12 overlap each other for each rotation of the upper mill 3 and slide down from the slide 12b. An appropriate amount of grain falls from the part to the grain adjustment hopper 7 and further falls to the grain supply hole 3c, and the desired powder is transferred from the periphery of the stone mill to the outside while the upper surface of the lower mill 6 and the rear surface of the upper mill 3 are rubbed. And the flour stored in the groove of the cylindrical powder receiving container 5 is swept with the brush 3b and taken out from the flour take-out hole 5b.
