Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing device for a vertical rice milling machine capable of polishing brown rice between an upright grinding stone-shaped grinding roll and a polishing net on the outer periphery thereof.

[0002]

2. Description of the Related Art Conventionally, a vertical rice milling machine having a grinding stone-like grinding roll and a polishing net on the outer periphery thereof is provided upright, for example, in Japanese Unexamined Patent Publication Nos. 3-262545 and 3-26.
As can be seen in Japanese Patent No. 2546 or Japanese Utility Model Publication No. 54-31977, a single grinding roll is adapted to rotate inwardly of a roux net.

[0003]

However, in such a structure, the grinding roll is apt to be squeaked, and the brown rice passing between the grinding roll and the millet net causes a bridging phenomenon, resulting in poor milling. Or, the polishing efficiency will be reduced, and the entire circumference of the grinding roll will always work,
As a result, the grindstone is likely to be clogged, and the sperm efficiency is likely to be reduced, as described above.

[0004]

SUMMARY OF THE INVENTION The present invention provides a solution to such a problem and further improves accuracy and efficiency of polishing, and therefore, it is provided on the outer circumference concentric circle of the vertical rotation shaft. Can be divided by vertically arranging a plurality of standing grinding rolls at intervals so that they can revolve along with the rotating shaft, and between the grinding rolls, a part of the outer circumference of each grinding roll can be projected outward. It is constructed by stretching a partition plate that can be installed.In addition, the upper and lower parts of each grinding roll are mounted on the support frame on the outer circumference of the rotary shaft, and the partition plate is fixed on the rotary shaft side. Use a wire mesh that can blow air from the inside to the outside, form each grinding roll in a cylindrical shape, form each grinding roll in a distorted shape on the outer periphery of the spindle, and rotate and fix the spindle of each grinding roll. You can freely
A large number of resistors that can control the flow of grains are arranged on the inner surface of the Hakusei net.

[0005]

Therefore, when each of the grinding rolls is rotated about the rotation axis so as to revolve, even if each of the grinding rolls about the rotation axis is squeezed, a part of the outer periphery of each grinding roll projects outward from the partition plate. Therefore, the brown rice passing between the rice bran net and the rice bran net does not cause the bridging phenomenon as in the past, and the brown rice smoothly flows between the partition plate and the protruding outer peripheral surface of the grinding roll. If the partition plate is used as a wire mesh to effectively blow air from the inside to prevent clogging, or if part of the outer periphery of each grinding roll protruding from the partition plate wears out, it will be ground accurately. By rotating the roll, the new surface can be projected outward from the partition plate for effective use.

1 to 5, FIG. 2 is a front sectional view in which a part of a vertical rice milling machine is shown as a cross section, in which a roasting net 1 having a large number of long holes 1a having vertical angles is provided upright. A hopper 9 is continuously provided above the upper part thereof, and a discharge port 10 for the polished rice is formed in a part of the outer periphery thereof which is the lower part of the starch netting 1, and an input pulley 11 is fixedly provided at the lower end to lower the A rotary shaft 2 erected on a lower support 12 extends vertically to the center of the lumber sponge net 1, and a long boss 2a is fitted and fixed to the rotary shaft 2, and the upper and lower parts of the boss 2a are fixed. The flat frame supporting frame 5 and the central part of the supporting frame 6 whose lower part has a frusto-conical shape are fitted and fixed to each other, and between the supporting frame 5 and the upper surface of the supporting frame 6 are six grinding stones. The cylindrical grinding rolls 3 are vertically erected at equal intervals on the outer peripheral concentric circles of the rotary shaft 2 and are respectively suspended. With the upper end of the support shaft 7 of the roller 3 is extended upward of the support frame 5, the upper end head 7 of the support shaft 7
A tightening nut 13 is screwed below a and each grinding roll 3 is configured to be rotatable and fixable. In addition, a partition plate 4 made of wire mesh is stretched between the grinding rolls 3 so that a part of the outer periphery of each grinding roll 3 can be projected outward and partitioned. The partition plate 4 as a whole has a cylindrical shape. Forming and fixing each partition support plate 4a extending from the intermediate portion of the partition plate 4 between the grinding rolls 3 and 3 to the outer periphery of the boss 2a,
A detachable cap 15 is attached to the upper part of the support frame 5 by a set bolt 14, and a ventilation passage 16 capable of blowing air is provided on the support base 12 between the partition support plates 4a.
A large number of resistors 8 capable of controlling the downward flow of the grain are provided on the inner peripheral surface of the Lingseed net 1 so that the grain can be milled while dropping the brown rice supplied from above. The third group of grinding rolls of the embodiment is equipped with a spiral body for feeding up and is configured so as to be able to graze while lifting the brown rice from the lower part to the upper part, or the grinding rolls and the gauze net are reversed. It can also be deployed and configured in a frusto-conical shape.

Therefore, when each grinding roll 3 is rotated in the direction of arrow A so as to revolve around the rotary shaft 2, the rotary shaft 2 is rotated.
Even if each of the central grinding rolls 3 is squeezed, a part of the outer periphery of each grinding roll 3 projects outward in an arc shape from the partition plate 4, so that the unpolished rice passing between the milling net 1 and The brown rice smoothly flows between the partition plate 4 and the protruding outer peripheral surface of the grinding roll 3 without causing a bridging phenomenon, and the rice is precisely refined between the rice polishing net 1 and the rice polishing net 1. The brown rice flowing down along the inner surface of the net 1 is in a state of flowing down moderately while being controlled by each resistor 8, and the milled rice is discharged from the discharge port 10.
From the wire mesh partition plate 4 between the grinding rolls 3, air is blown from the inside as shown by the arrow B, clogging is prevented, and bran etc. are effectively removed from the bran net 1. If a part of the outer periphery of each grinding roll 3 protruding from the partition plate 4 is worn away, the upper nut 13
When the grinding roll 3 is rotated and the new surface is projected outward from the partition plate 4 and the nut 13 is tightened as shown in FIG. 5, the grinding roll 3 can be effectively used without replacement. .

FIG. 6 shows another example of the grinding roll, in which the grinding roll 3 of the grindstone formed around the support shaft 7 is formed in a distorted shape as shown in the same manner as in the above embodiment. As shown by the arrow C, the grinding surface can be projected to the outside of the partition plate 4 while rotating, so that the roll structure can reduce the material cost.

[0009]

As described above, according to the present invention, when the grinding rolls (3) are rotated about the rotating shaft (2) so as to revolve, the grinding rolls (3) around the rotating shaft (2) are squeaked. However, since a part of the outer circumference of each grinding roll (3) projects outward from the partition plate (4), brown rice passing between the polishing roll (1) and the rice bran net (1) does not cause a bridging phenomenon as in the past. ,
The brown rice smoothly flows between the partition plate (4) and the protruding outer peripheral surface of the grinding roll (3), so that the brown rice can be accurately and efficiently polished with the polishing net (1). When (4) is made into a wire net, it is possible to prevent clogging while effectively blowing air from the inside, and when the grinding surface protruding from the partition plate (4) of each polishing roll (3) is worn away, the grinding roll Rotate (3) to partition the new grinding surface (4)
Since it can be effectively used while protruding further outward, it has a feature that it can be suitably implemented as a polishing device that further improves polishing accuracy.
