Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grinding type rice polishing roll.A conventional Kongo grinding type rice polishing roll is formed into a hollow truncated conical shape A shown in FIG. , the upper part is bead-shaped and the lower part is cylindrical, as shown in FIG. 2, and in both cases, it is formed in the shape of a hollow pipe.

Therefore, manufacturing this roll is quite troublesome and can only be produced at a factory with specialized equipment, and cannot be easily manufactured at a non-specialized factory.

Furthermore, if any part of the roll is damaged, it cannot be repaired even if the other parts are intact, so the entire roll must be disposed of.

Another disadvantage of the roll is that it is expensive because it requires a lot of effort to manufacture.

The present invention aims to overcome the deficiencies of the known examples described above.

Furthermore, the present invention makes it possible to obtain a grinding roll that is significantly cheaper than conventional ones.

Furthermore, the present invention enables formation by a much simpler method than conventional methods.

The gist of the present invention is a grinding type rice milling roll in which a plurality of rod-shaped diamond grinding bodies are attached in parallel to the outer surface of a rotating body in the generatrix direction by any means.

To explain with the drawing, 1 is a vertical grain feeding spiral, and a double spiral 3.3'' is integrally formed on the outer circumferential surface of the metal cylindrical portion 2. The grain feeding spiral 1 is formed of metal casting, and is formed separately from a mounting portion 4, which will be described later, and the grain feeding spiral 1 and the mounting portion 4 are connected at a joint by a bottle or the like.

The cross section of the mounting portion 4 has a cylindrical portion 5 on the inside and several flat mounting surfaces 6 on the outside. The mounting surface 6 in the embodiment is formed on both the front and rear surfaces and the left and right surfaces, and has a square bar shape, and a corner portion 7 has a square groove 8 formed toward the center.

The square groove 8 is formed in the shape of a slit over the entire top and bottom of the corner 7 of the attachment part 4, and a roll presser 9 is provided to fit into the square groove 8. The roll presser 9 has a structure that fits snugly into the square groove 8 from the outside, and its inner surface 10 fits into the groove bottom 11 of the square groove 8 with a slight gap formed therein.

When the roll presser 9 is fitted into the square groove 8, its outer surface 12
protrudes above the square groove 8, and the outer surface side 12 forms a presser portion 13 that opens outward on the tea bar as it goes outward.

Screw holes 14.14 are formed at both upper and lower ends of the groove bottom 11 of the square groove 8, and through holes 15.15 are formed at positions corresponding to the screw holes 14 at both upper and lower ends of the roll presser 9. Reference numeral 16 denotes a set screw, which is screwed into the screw hole 14 after passing through the through hole 15.

This fixes the roll presser 9 within the square groove 8.

At this time, the gap between the inner surface 10 and the groove bottom 11 has the effect of reliably tightening the set screw 16.

A communication port 18 communicating with the center portion 17 of the mounting portion 4 is formed at an intermediate position between the screw holes 14 and 14 of the square groove 8. Communication port 18
is formed rather on the lower side.

The roll presser 9 is formed with an air jet port 19 at a position corresponding to the communication port 18.

A rotating shaft 20 made of a hollow pipe is fitted inside the mounting portion 4 . The inner part of the screw hole 14 becomes a cylindrical part 21 that protrudes inward, and the inner surface 22 of the cylindrical part 21 has a structure that fits tightly against the outer surface 23 of the rotating shaft 20 (note that there is a slight gap between the outer surface 23 and the inner surface 22). may form a gap).

A plurality of through holes 24 are formed in the rotating shaft 20, and the inside of the rotating shaft 20 serves as a ventilation passage 25, which is connected to a blower. That is,
After passing through the ventilation passage 25, the wind blows out from the through hole 24, passes between the rotating shaft 20 and the mounting part 4, blows out from the communication port 18, and further blows out from the jet p19.

The roll presser 9 fits into all the square grooves 8.8,
A rod-shaped diamond grinding body 26 is held between the presser parts 13 and the presser parts 13 facing each other.

The width of both left and right sides 27 of the Kongo grinding body 26 increases toward the inside (bottom surface) so as to be sandwiched between the presser portions I3. The inner surface (bottom surface) 28 of the Kongo grinding body 26 has a structure that is attached to the mounting surface 6, and the manufacturing order is that the Kongo grinding body 26 is brought into contact with each mounting surface 6, and then a roll press is applied to press it down. 9 and secure it with a set screw 16.

Next, I will explain the effect.

Since the grinding rice polishing roll of the present invention has the configuration described above,
First, fit the handle 41 part 4 on the outer periphery of the rotating shaft 20, and
Send grain to! 1 + Jg spiral 1 is fitted, the grain feeding spiral 1 and the attachment part 4 are connected to the clutch at the joint part, and the front, rear, left and right sides of the attachment part 4 (= 1 surface 6 is brought into contact with the inner surface 28 of the Kongo grinding body 26, and each corner is Place the roll presser 9 on part 7, and press the roll presser 9.
When inserted into the square groove 8, the presser portions 13.13 on both sides of the roll presser 90 engage with the left and right sides 27 of the diamond grinding body 26. In this state, when the through hole 15 and the screw hole 14 are aligned and the set screw 6 is inserted into the through hole 15 and screwed, the Kongo grinding body 26 is easily stopped on the outer periphery of the attachment part 4 and the grinding type rice polishing roll can be obtained.

However, after polishing the rice, any one of the Kongo grinding bodies 2
6 is damaged, loosen the set screw 16,
It is only necessary to replace it, and there is no need to replace the other Kongo grinding bodies 26.

During rice milling, the wind emitted from the blower is passed through ventilation passage 2.
5, passes through the through hole 24 between the outer surface 23 and the cylindrical portion 5, and blows through the communication port 18 to the jet port 19.

The present invention is as described above, and since the Kongo grinding body 26 is rod-shaped and not hollow cylindrical as in the conventional case,
Since it is easy to form a mold for the fired casting, it is easy to manufacture, and the cost is extremely low. Also, if a part of the S is damaged, only that part needs to be replaced, which is advantageous.

Furthermore, since it is attached using a rod-shaped roll presser 9, it is easy to remove it.
