With reference to these drawings, the configuration of the millstone system for a grinder of the present invention will be described in detail as follows.

That is, as shown in Figures 4 and 5, the millstone system for a grinder of the present invention includes the components of the fixed millstone 100 on the upper side and the rotary millstone 200 and the rotary blade piece 300 on the lower side. do.

The fixed millstone 100, which is a component of the invention,

The grain input hole 110 penetrated in the center and the first inclined groove 130 dug in a downward direction across the lower horizontal grinding surface 120, the direction opposite to the centrifugal force discharge direction of the grain deeper in this first inclined groove portion The grinding guide groove 140, which is dug in an inclined state to the horizontal grinding surface, and the tip thereof is extended, between the grinding guide groove 140 and the grinding guide groove 140, and a striking projection protruding from the grain input hole 110 (150) is configured.

At this time. The striking protrusion 150 protrudes between the inlet and the inlet of the grinding guide groove 140 .

The rotary mill 200, which is a component of the present invention,

The shaft fixing part 210 protruding in the same direction as the grain input hole 110, forming an assembly guide groove 230 opposite to the inner circumferential surface, and having a penetrating fixing shaft hole 220, the lower horizontal grinding surface 120 The second inclined groove part 250 of the upper and lower slopes facing the first inclined groove part 130 over the upper horizontal grinding surface 240 opposite to the second inclined groove part 250, the grinding induction groove 140 in the second inclined groove part 250 As the centrifugal force direction of the grain discharging in the opposite direction to the direction of the centrifugal force, it is made by protruding the grain shoveling protrusion 260 inclined downward from the upper part of the shaft fixing part 210 to the outer side of the second inclined groove part 250 .

The rotary blade piece 300, which is a component of the present invention, is coupled to the lock shaft 310 through the fixed shaft hole 220 of the shaft fixing part 210 of the rotary millstone, and the grain input hole 110 of the fixed millstone 100 ) is coupled to the stirring blade 320 in a penetrating state.

At this time, the stirring blade 320 has a space 320a in the center and is formed as a pair of striking and stirring blade pieces divided on both sides, each of which protrudes the stepped protrusion 320b whose outer side is extended to the space ( 320a) minimizes the rotational load due to rotation, and the stepped projections 320b on both sides cooperate with the striking projections 150 of the fixed millstone 100 to provide a stirring operation and a striking operation at the same time to provide more effective grain of grinding agitation is provided.

The rotary blade piece 300 is formed on the left and right sides of a pair of support plate 350 and the rotary mill 200 for synchronous rotation, which are shaft-coupled to the motor shaft M-1 of the drive motor M. While the stirring blade 320 rotates, a stirring operation is performed to push the input grain into the grinding induction groove 140 of the first inclined groove 130 of the fixed millstone.

6A and 6B , the rotary mill 200 has a shaft pipe 360 protruding from the lower part of the fixed shaft hole 220 of the shaft fixing part 210 through the assembly guide groove 230 at the top of the shaft fixing part 210 is opposite to the outer peripheral surfaces of both sides. The support plate 350 is supported by the slide insertion of the protruding guide groove protrusion 370, and the rotary blade piece 300 is in the guide groove 371 formed inside the guide groove projection 370 of the shaft tube 360. Inserted vertically and coupled to the L-shaped lock groove 372 formed opposite to the horizontal direction by rotation of the lock protrusions 311 protruding on both sides of the lock shaft 310, the lock shaft 310 is formed on both upper sides of the lock shaft 310. The stirring blades 320 are coupled to penetrate the grain input hole 110 of the fixed millstone 100 in a state of being coupled.

At this time, it is preferable that the grinding guide grooves 140 of the fixed millstone 100 have a predetermined interval in the rotational direction of the rotary millstone 200 and the tip is extended to form six inclined lines.

These grinding guide grooves 140 may be composed of 4, which is less than 6, which is suggested as a preferred embodiment of the present invention, and it is possible to have 8 to 10 more than that, but in terms of efficiency of the function and molding interval according to the grinding. Six were the most preferred.

7 to 10, the core technology of the present invention is the grain input through the grain input hole 110 of the upper fixed millstone 100 is the rotation of the stirring blade 320 of the rotary blade piece 300. In the same direction as the grain input hole 110 of the fixed millstone 100 at the same time as the stirring operation in the centrifugal force direction by evenly dispersing, the striking projection 150 protruding between the inlet and the inlet of the six grinding induction grooves 140 By the blow, it is pushed into the entrance of the grinding guide groove 140 at the same time.

The grains put into the space (see FIG. 6b ) formed between the second inclined groove part 250 of the rotary mill 200 and the first inclined groove part 130 of the fixed millstone 100 are rotated at the same time as this operation. Grain by centrifugal force is blown while pushing the grain by the grain thrust striking protrusion 260 of the millstone 200 and discharged in the centrifugal force direction and continuously sprayed into the six grinding guide grooves 140 of the fixed millstone 100 this will be pushed in.

In this way, the grains pushed into the six grinding guide grooves 140 are fine particles by the grinding gap between the lower horizontal grinding surface 120 of the fixed millstone 100 and the upper horizontal grinding surface 240 of the rotary milling stone 200 . It is released as it is crushed.

In other words, the grinding induction groove 140 has a striking protrusion 150 protruding between the inlet and the inlet of the grinding induction groove 140 at the same time as the stirring action of the stirring blade 320 of the rotary blade piece 300 and The grain by the centrifugal force is crushed and pushed in at the same time as the grain by the centrifugal force due to the cooperative action of the grain crushing protrusion 260 of the rotary mill 200 .

The grinding guide groove 140 is a sloped surface, and the entrance of the grain input hole 110 side is wide and the fixed millstone 100 and the rotary millstone 200 have a grinding gap between the upper and lower horizontal grinding surfaces 120 and 240. Grains are easily crushed and discharged by continuously pushing and inducing coarsely crushed grains by shape or centrifugal force.

In the present invention, the grinding guide groove 140 is molded to a size (width of the valley) that can provide a smooth flow of grains in a limited size of the fixed millstone 100, but the fixed millstone 100 If the number of moldings is 6 or more from the grain input hole 110 side to the lower horizontal grinding surface 120 side, the formed interval on the outer circumferential surface of the grain input hole 100 is too narrow, so it is easily broken during high-speed rotation There was a problem with

If there are 6 or less grinding guide grooves 140 , molding may be possible in a limited size, but the grain transferred to the upper part by the high-speed rotation of the rotary mill 200 is the lower horizontal grinding surface 120 of the fixed millstone 100 . ), the grain to be pulverized could not be transferred smoothly due to the weak discharge inducement, and the rotation load of the rotary mill 200 was generated due to the accumulation of grains, so it was most preferable to be molded into six pieces.

In addition, the grain stirred in the centrifugal force direction by the striking protrusion 150 protruding between the inlet and the inlet of the grinding induction groove 140 is easily pushed into the inlet of the grinding induction groove 140 to induce grinding. Evacuation is provided to provide a quick grinding action.

And the grain shoveling protrusion 260 of the rotary mill 200 has a tip extending in the opposite direction to the rotational direction, and at the same time, the top surface is inclined toward the tip and the side surface is narrowly formed to form four oblique lines. 200) while hitting the grain with the first inclined groove 130 of the fixed millstone 100 according to the high-speed rotation, it is sprayed upward while simultaneously taking a shape to reduce the rotational load as much as possible.

That is, the grain input through the grain input hole 110 of the fixed millstone 100 falls into the second inclined groove part 250 and at the same time the grain shoveling protrusion 260 rotates while pushing the dropped grain. At the same time, it is sprayed on the upper part in the direction of centrifugal force.

At this time, in the shape of the grain shovel striking projection 260, it is formed obliquely in the centrifugal force direction, thereby smoothly guiding discharge to the upper horizontal grinding surface 240 and at the same time, in the shaft fixing part 210, the horizontal grinding surface 240. As the incline is low as it goes down, coarsely pulverized grains push centrifugal force while excess grains are ridden, eliminating excessive load and minimizing rotational load.

Of course, the number of the grain shovel protrusions 260 may take a structure of four or more, but the space occupied by the second inclined groove portion 250 between the grain shovel protrusions 260 is small, so coarsely pulverized grains according to rotation There is a disadvantage in that it cannot ride smoothly and a rotational load is generated, and when there are less than 4, the action of sprinkling coarsely pulverized grains to the upper horizontal grinding surface 240 is weak, and the lower horizontal of the fixed millstone 100 The four presented in the present invention were preferred as the induction action to the grinding guide groove 140 was weak due to induction of a gap between the grinding surface 120 and the upper horizontal grinding surface 240 (grinding gap) between the grinding surface 120 and the upper horizontal grinding surface 240, resulting in poor grinding efficiency. .

In the present invention as described above, the grain is stirred in the centrifugal force direction by the stirring blade 320 of the rotary blade piece 300 at the same time as the input of the grain, and six pieces formed in the opposite direction to the centrifugal force direction of the fixed millstone 100 are The second inclined groove portion ( 250) by spraying the grains falling on the upper fixed millstone 100 upwardly into the first inclined groove 130 of the upper fixed millstone 100, and the action of pushing by centrifugal force into the entrance of the crushing dudo groove 140 simultaneously acts. The grain is continuously crushed in the grinding gap formed between the lower horizontal grinding surface 120 of the fixed millstone and the upper horizontal grinding surface 240 of the rotary millstone 200 to minimize the rotational load by discharge and at the same time provide a rapid grinding action There is an advantage to

As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims and equivalents as well as the claims to be described later.
