DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polished sand roll for use in a rice mill.

[0002]

2. Description of the Related Art Conventionally, there is a type in which a plurality of crushed sand mill rolls b are combined with a crushed sand mill roll b fixed to a rotating shaft a. In this configuration, if you tighten strongly from the top and bottom,
Rolls of polished rice sand b are damaged. FIG. 1 shows a case in which a metal annular core metal c is attached to the inside of a roll of polished sand milled rice b. Since the metal annular core metal c is provided, the metal annular core metal c is not damaged even if it is strongly tightened from above and below.

[0003]

The known example of FIG. 1 is as follows.
The cost is increased because the metal ring core c is attached to all the rolls of the polished sand mill rice a. In the present application, even if there is no metal core metal c, it is a polished sand mill roll that does not need to be tightened with a very strong force, and is aimed at cost reduction.

[0004]

Accordingly, the present invention relates to a part of a configuration in which a plurality of crushed sand mill rolls 6 fixed to the rotating shaft 1 are combined with a plurality of crushed sand mill rolls 6. A metal ring core 38 is attached to the inside of the metal sand core roll 6 to obtain a metal sand core roll having the metal ring core and a metal sand core roll not having the metal ring core. Numeral 38 designates a polished sand mill roll fixed to the rotating shaft 1 by a key 39.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a hollow vertical rotating shaft, which is mounted on the fixed cylinder 4 by bearings 2 and 3. The vertical rotation shaft 1 protrudes below the fixed cylinder 4, and the passive pulley 5 is fixed thereto. Vertical rotation axis 1
Is projected above the fixed cylinder 4, and the discharge roll 7 is fitted into the upper protruding portion from above.
Is fitted from above, and then several divided annular crushed sand milling rolls 6 are fitted from above, and then a metal upper flange 35 is fitted from above, and tightened up and down with nuts 36 to fix it up and down.
The rice sand roll 6 has a large diameter on the upper side and a slightly smaller diameter on the lower side, and has an inverted truncated cone shape.

[0006] Of the above-described crushed sand mill rolls 6, the lowest crushed sand mill roll 6 is attached to a metal annular core 38.
The metal annular core 38 is fixed to the rotating shaft 1 by a key 39.
No core metal is used for the crushed sand mill roll 6 thereon, and the crushed sand mill roll 6 thereon is mounted on the metal ring core 40, and the metal ring core 40 is attached to the rotary shaft 1 by the key 41. Fixed. No core metal is used for the uppermost sand roll rice roll 6. In this way, the sand-milled rice roll 6 having the metal ring core 38 and the metal ring core 40 receives the rotating force directly from the rotating shaft 1, and therefore can be rotated without tightening the nut 36 with too much force. To prevent damage to the rice sand roll 6.

[0007] A small diameter portion 8 is formed in the abutting portion between the upper part of the discharge part roll 7 and the lower part of the metal lower flange 34, and the bearing 9 is fitted therein, and the inner ring 10 is mounted outside the bearing 9. The outer periphery of the Kongo sand milling roll 6 is surrounded by a bran removing tube 11 similar to the Kongo sand milling roll 6, and a rice milling chamber 31 is formed between the Kongo sand milling roll 6 and the bran removing tube 11. I do.

[0008] The bran removing cylinder 11 is suspended by a right inclined ring 12. Reference numeral 13 denotes a guide cylinder provided at an upper position of the sand and rice mill roll 6, and a gear 14 is fitted on the outer periphery of the guide cylinder 13, and a gear 1 is provided.
4 meshes with a gear 16 of a motor 15. The upper end of the right inclined ring 12 is axially fixed to the guide cylinder 13, and the lower end of the right inclined ring 12 is axially fixed to the bran removing cylinder 11. The upper end of the left tilt ring 17 is locked to the gear 14 via a fixture, and the lower end of the left tilt ring 17 is locked to the bran removing cylinder 11. Therefore, when the motor 15 is energized and the gear 14 is rotated clockwise through the gear 16, the upper end of the left inclined ring 17 moves rightward, and the lower end of the left inclined ring 17 does not move rightward, so moves downward, and the left inclined ring 17 moves downward. The ring 17 gradually becomes vertical. When the left tilt ring 17 becomes vertical, the right tilt ring 12 also becomes vertical, and the bran removing cylinder 11 descends. When the rice bran cylinder 11 moves down, the rice bran cylinder 11
The milling room 31 which is a gap between the sand milling roll 6 and the sand is widened.

An annular derivative 18 fixed to the lower end of the bran removing tube 11 is provided at a position facing the metal lower flange 34.
An outer ring 19 fixed to the upper surface of the fixed cylinder 4 is provided below the annular derivative 18. Reference numeral 20 denotes a resistor, inside a discharge port 21 opened to the outer ring 19,
The outlet 21 is positioned so as to close and is fixed to the outer surface of the inner ring 10 by screws 22. A discharge gutter 23 is attached outside the discharge port 21, and a vertical rod 24 is attached to the discharge gutter 23.
Is provided, and a projection 26 protruding from a boss 25 mounted on the vertical rod 24 is inserted into an engagement hole 27 formed in the resistor 20. Reference numeral 28 denotes a spring, one end of which is engaged with the projection 26 and the other end of which is engaged with the discharge gutter 23 to resiliently pull the projection 26 so that the resistor 20 always covers the discharge port 21. 2
9 is an adjusting screw for adjusting the spring 28, 30 is an adjusting screw 29
, 32 is a hopper, and 33 is a valve. A blow hole 37 is formed in all or a part of the metal lower flange 34 at positions a, b, and c.

[0010]

Next, the operation will be described. When the brown rice is supplied to the hopper 32 and the valve 33 is opened, the rice flows into the rice milling chamber 31 from the guide cylinder 13, is milled by the action of the sand roll 6, and is milled downward. At this time, since the Kongo sand polished roll 6 has a stack of several polished sand polished rolls 6, the nut 36 is usually tightened with a strong force. Although the roll 6 was damaged, the present application is based on the assumption that the lowermost crushed sand milling roll 6 is attached to the metal ring core 38, and the metal ring core 38 is fixed to the rotating shaft 1 with a key 39, and Although the core sand is not used for the roll 6 of the polished sand mill, the roll 6 of the polished sand mill is mounted on the metal ring core 40, and the metal ring core 40 is fixed to the rotating shaft 1 by the key 41. Since the metal sand core 38 and the metal sand core roll 6 having the metal shell 40 receive the rotating force directly from the rotating shaft 1, the nut 36 can be rotated without tightening the nut 36 with a very strong force. To prevent damage to the rice sand roll 6.

[0011]

Conventionally, there is a type in which a plurality of polished sand mill rolls b are combined with a crushed sand mill roll b fixed to the rotating shaft a. In this configuration, if the roll is strongly tightened from above and below, the sand baking roll b is broken. FIG. 1 shows a case in which a metal annular core metal c is attached to the inside of a roll of polished sand milled rice b. Since the metal annular core metal c is provided, the metal annular core metal c is not damaged even if it is strongly tightened from above and below. In the known example of FIG. 1, since the metal annular core metal c is attached to all the rolls of polished sand mill rice a, the cost increases. The present invention relates to a configuration in which a plurality of crushed sand mill rolls 6 fixed to the rotating shaft 1 are combined with a plurality of crushed sand mill rolls 6. A metal core 38 is attached to form a polished sand mill roll with the metal ring core and a crushed sand mill roll without the metal ring core, and the metal ring core 38 is fixed to the rotating shaft 1 by a key 39. Because the metal ring core 38 was fixed to the rotating shaft via the key 39, the roller was made of a metal sand core and a metal sand core roller having a metal ring core. It is possible to reduce the cost by using a roller made of polished sand without a metal ring metal core and rotating it without tightening it too much.
