Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing and grinding blade crusher,

The present invention relates to an internal grinding net and a grinding blade structure of a grain grinder, and more particularly, to an internal grinding net and a grinding blade structure for grinding and discharging grain, Wherein the discharge hole is formed such that a slope is formed in an inner circumferential surface of the discharge hole in the scattering direction of the pulverized grain so that the discharge can be performed quickly, the inner grinding net and the grinding blade structure of the grain grinder.

1, the front and rear side mantle 13, which is formed in a ring shape, is installed as a spacing holder 14 so as to be spaced from the front and rear side mantle 13, And a filter net 12 formed by perforating a stainless steel plate on the inner circumferential surface between the outer circumferential surface and the outer circumferential surface.

The filter mesh assembly 11 is installed in a crusher (not shown) of the grain crusher, and a movable cutter (not shown) is installed in the inner space of the filter mesh assembly 11 so as to be rotated by a motor, The crushed material is crushed in the process of colliding with the movable cutter (the dried grain, the dried seafood, the dried food material such as the herbal medicine) injected into the inner space of the main body 11.

The reason why the pulverized powder that is smaller than the small holes formed in the filter net 12 in the process of pulverizing the pulverized object passes through the pulverized powder is that the inside of the pulverizing passage in which the filter net assemblage 11 is inserted is connected The pulverized powder that is pulverized at the inside of the filter net 12 escapes to the blower side due to the suction force generated in the blower (not shown).

1, when the movable cutter, which rotates inside thereof, hits the pulverized object, the hard pulverized object is repelled in the radial direction by the force hitting the movable cutter And the crushed object so bounces strongly against the inner peripheral surface of the filter net 12 made of a thin stainless steel perforated plate.

Therefore, damage such as crushing of the filter net 12 made of a thin stainless steel perforated plate is deteriorated, and the filter net 12 out of the filter is broken to fail to exhibit its original function. There is a problem that the operation is interrupted due to the replacement of the filter net 12 that is so damaged and the cost of replacing the filter net is excessively increased.

As a prior art for solving the above problems, Patent Citation No. 1571873 (published on Nov. 25, 2015) "Grain crushing device" is a device for blowing the power of a motor to be driven, And a plurality of movable cutters mounted on the outer circumference of the rotating body, which is connected to a rotating shaft for rotating the impeller of the blower and is installed inside the pulverizing vessel, Wherein a flange is formed on the outer periphery of the rotary body at the rear side of the movable cutter and the flange is provided with a filter net blocking the inlet of the suction pipe so that the pulverized powder pulverized in the pulverizing cylinder is rotated at a right angle And the outer periphery of the filter net and the inner periphery of the suction port in front of the blower, Is characterized in that between the filtering net includes a configuration to place a predetermined gap to be installed.

In the prior art constructed as described above, since the filter net is provided in the cutter assembly, a portion where the discharge of the grain is not easy, and a portion in which the crushed grain is struck against a mantle formed between the opening portion and the opening portion, There is a problem that a certain amount of crushed grains is discarded because crushing is performed finely as it is crushed again.

That is, there is a problem in that the crushed grains do not escape properly because the direction in which the grains crushed by the movable cutter moves and the direction in which the filter net is formed are not made at the same angle.

Another prior art for solving the above problems is disclosed in Korean Patent Laid-Open Publication No. 2005-104880 (Nov. 3, 2005), "Grain grinding blade and method of manufacturing the same" is a grinding mill in which a certain amount of grain is fed through a hopper And a plurality of grinding blades are coupled to the fixing jig in a multi-stage shape and rotated by a power transmission device.

At this time, the grinding blade is made of a general metal or a special steel having high strength, and is formed in a flat plate shape in the form of a rectangular plate, and a powdery cemented carbide member is fused to a part of the crushing blade.

Thus, while the crushing blade is rotated by the power transmission device, the grain fed to the crusher is pulverized.

In addition, an inner grinding barrel is provided on the outer side where the grinding blade is installed, and a through hole is formed in the inner grinding barrel so that the grinded grain is discharged through the through hole.

The through holes formed in the inner grinding cylinder are formed in the horizontal direction as the direction in which the blades are formed as shown in the drawings of the patent publication and the through holes formed in the horizontal direction are formed in the direction perpendicular to the side of the inner grinding cylinder, There is a problem in that the commodity of the crushed grains is deteriorated because the grain crushed by the crushed grains does not escape into the through hole of the inner crushing tube and is continuously crushed.
