Abstract

PURPOSE:To effectively clean unpolished rice between a cleaning net and a grinding roll by freely turnably installing a grinding roll mounted with grinding bodies on its outer periphery within the cleaning net and providing the circumference of the cleaning net with blind plate parts proximate to the grinding bodies at prescribed intervals and disposing perforated iron plate parts curved outward between the adjacent blind plate parts. CONSTITUTION:The grinding roll A mounted with the plural grinding bodies (a) which build up toward the outside at spaced intervals on its outer periphery is freely turnably installed in the fixed cleaning net B. The blind plate part 1 of the short length in the extreme proximity to the foremost ends of the grinding bodies (a) are disposed at every other prescribed interval around the cleaning net B respectively and the perforated iron plate parts 2 of the long length curved to bulge-form outward are disposed between the adjacent blind plate parts 1 respectively. Namely, the unpolished rice is well rolled and effectively cleaned while the unpolished rice is increased in pressure in the state that the grinding bodies (a) push the unpolished rice toward the blind plate part 1 side inward of the perforated iron plate parts 2. Bran cut is improved in the state that the grinding bodies (a) press the unpolished rice toward the perforated iron plate 2 side from the blind plate part 1 side.

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 rice polishing machine capable of effectively polishing brown rice between a polishing net and a grinding roll.

[0002]

2. Description of the Related Art Conventionally, in a rice-polishing machine which is constructed by rotatably pivoting a grinding roll having a plurality of upwardly-ground grinding bodies mounted on the outer periphery at intervals with a fixed rotation. ,
For example, as seen in JP-A-5-49954,
It is known to make the sprout net into a square tube.

[0003]

However, in such a lumber sponge net of a square tube, the pressure on the brown rice inside the corner is extremely low, and the brown rice stagnates or the rolling property deteriorates.
Moreover, in the pressure-reducing and pressure-increasing parts before and after the corners, excessive pressure is applied to the surface of the net and damage to the spermatogonial net becomes faster. It had a problem that it was not good.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and further improves the polishing performance so that it can be preferably implemented. Therefore, a grinding body is provided around the polishing net. Short blind plates that are closest to the most distal end are formed at predetermined intervals, and a long perforated iron plate that is curved outwardly between adjacent blind plates. Each blind plate portion is formed in an arc shape, each blind plate portion is formed in a flat plate shape, and at least the outer peripheral side of each blind plate portion is formed. A reinforcing support is mounted, and each grinding body is formed by alternately stacking a large number of steel plates and ventilation spacers so that the outer peripheral surface is formed into an uneven surface.

[0005]

[Function] Therefore, in a state where the grinding body pushes the brown rice toward the blind plate side inside the perforated iron plate portion, the brown rice can be tumbled well while pressurizing effectively, and at the same time, the blind plate portion side can be effectively polished. In the state where the grinding body pushes the brown rice toward the side of the perforated iron plate, the brown rice can be slightly expanded while depressurizing the so-called bran breakage.

1 to 5, FIG. 2 is a sectional side view of a part of a vertical rice milling machine, which is located below a milling net B standing upright below a hopper 6 opening upward. A brown rice discharge port 7 is formed in a part of the outer circumference, and an input pulley 8 is fixedly provided at the lower end portion and a grinding roll A is mounted on a rotary shaft 10 mounted on a support base 9. A is a rotary shaft cylinder 13 having a large number of air outlets 12 installed on the outer periphery of the rotary shaft 10 having a support frame 11 installed on the lower portion, and the support shaft 11 is provided on the outer periphery of the rotary shaft 10. On the outer periphery of the rotary shaft cylinder 13 above the frame 11, as shown in FIG. 3, six engaging recesses 14 having an open inner side are formed at equal intervals and adjacent engaging recesses are formed. A wire mesh 15 having a curved shape with a high front and a low front is stretched between 14 in the direction of rotation, and each engaging recess 14 has a bottom surface. A large number of steel plates 4 having a large number of ventilation holes 16 and a spacer 5 formed in a corrugated shape so as to allow ventilation are alternately polymerized, and the outer peripheral surface thereof is an uneven surface so that it becomes a curved surface of front low rear high in the rotation direction a. The case 17 to which the grinding body a formed in the above is mounted is fitted, and the screw 19 inserted into the support lid 18 attached above each case 17 is screwed into the screw hole 20 on the case.
A cap 21 is attached to the upper side of the support lid 18 so as to be configured.

In the six equally distributed regions around the lumber sponge net B, a concave circular arc is formed outward while approaching the most distal region b of the grinding body a, which has the largest diameter, and has a length L _1. A short blind plate portion 1 is formed, and a perforated iron plate portion having a long length L ₂ having a large number of punched holes 2a that are largely curved outward in a bulge shape between adjacent blind plate portions 1 Each of the blind plate portions 1 is formed into a flat plate shape, as shown in FIG. It can also be installed and configured.

Therefore, when forming the sponge net B, in order to bend the perforated iron plate portion 2 outward,
As shown in FIG. 4, each punching hole 2a is deformed into a frustoconical shape so that it can pass through the bran without clogging, and when polishing brown rice, the outer circumference of the grinding roll A is cut. In the state in which each of the raised grinding bodies a is rotated in the direction of the arrow A while pushing the brown rice toward the blind plate portion 1 side inside the perforated iron plate portion 2, the brown rice rolls well while increasing the pressure. In the state where the grinding body a pushes the brown rice from the blind plate portion 1 side toward the perforated iron plate portion 2 side, the brown rice is made to swell slightly while depressurizing the brown rice. The bran break can be improved, and the bran sperm net B can reasonably perform the bran sperm action.

[0009]

As described above, according to the present invention, the perforated iron plate portion (2)
In the state where the grinding body (a) pushes the brown rice toward the blind plate portion (1) side inwardly, it is possible to roll the rice well while pressurizing the brown rice, and effectively polish the rice. In the state where the grinding body (a) pushes the brown rice from the 1) side toward the perforated iron plate part (2) side, it is possible to make the so called bran breakage by making the brown rice slightly swelled while lowering the pressure. As a result, the polishing performance can be further improved compared to the conventional type, and the polishing action is performed without applying too much load to the polishing network (B), which means that it can be effectively used. It has a feature that it can be easily manufactured and can be suitably implemented.
