Description

Grain Grinders {GRAIN GRINDER}

The present invention relates to a grain grinder, and more particularly, to prevent the incorporation of powder into the ground material while minimizing the generation of frictional heat during the milling of the ground material such as grains or vegetables using the principle of soft milling. Of course, by preventing the destruction of the nutrients contained in the grinding object, and by mixing the grains and vegetables to process at once, it is possible to efficiently crush the grinding object, and to consolidate the power transmission unit and the grinding unit The present invention relates to a crusher that can be installed and miniaturized.

In general, as a grinding device for grinding the milled products such as grains such as beans and peppers, there are traditional tools such as mortar and millstone. The mortar is to grind or grind the grinds in a repetitive operation of putting the grinds in the mortar and lowering them up and down using a mortar ball. The grind | pulverized object is grind | pulverized by the frictional force between the upper and lower millstones by placing a grind | pulverized object into the hole formed in the upper millstone, and turning a knob.

However, since such mortars and millstones are made by hand, it is inevitable to take a lot of force, and thus requires a lot of grinding time, and also can not be processed by mixing grains and vegetables at once. Noise pollution is greatly generated at the time, and there are disadvantages such as polluted matter or crushed material being scattered to the outside to pollute the surroundings.

In order to supplement the disadvantages of the traditional tools, there has been known in the prior art an automatic crushing device for pulverizing the pulverized object by the rotational friction while rotating at a high speed with the rotational force of the drive motor.

However, the conventional automatic grinding device has a drawback of destroying a protein, which is one of nutrients contained in grains, by generating a lot of frictional heat as the pulverized body made of natural stone or diamond is rotated at high speed by a driving motor. In particular, when used for a long time in a high-speed rotation state there was a tendency that the crushed body is worn, thereby causing a significant amount of stone powder to be mixed in the pulverized material or the pulverized product, thereby reducing the quality of the pulverized product. Moreover, the conventional automatic grinding device is cumbersome in the work because the worker has to separately mix the ground material in order to grind the ground material evenly even if the ground material is ground by automatic control. There was a problem.

Accordingly, the present invention has been made to solve the above-mentioned problems, and by using the principle of soft spinning, it is possible to minimize the generation of frictional heat during the pulverization of pulverized products such as grains or vegetables, while the powder is mixed in the pulverized material. In addition to preventing the destruction of the nutrients contained in the grind, it is also possible to process grains and vegetables at once, and to prevent the grind from being scattered to the surroundings. It is an object of the present invention to provide a grain grinder capable of miniaturization by intensively installing the power transmission unit and the grinding unit.

In this way, the pulverized product in the rotary grinding cylinder 30 can be easily discharged to the outside using the operation lever 50. Further, a stopper 52 is provided through the vertical support pieces 41a and 41b and the bearing blocks 42a and 42b so as to stop the rotary grinding cylinder 30 at a desired position. The position of the stopper 52 may be appropriately changed.

Grain grinder according to the present invention configured as described above, while the rotary grinding cylinder 30 is rotated together in accordance with the rotation of the stone plate 31, similar to the grinding principle of the conventional traditional tools, the stone plate 31 is rotated The to-be-ground grind | pulverized object thrown in into the rotary grinding cylinder 30 can be minutely grind | pulverized by the friction force between a pair of roller-type soft stones 32a and 32b fixed on the surface. Moreover, such a grain grinder is operated in a state of low speed rotation by a speed reducer, so that the generation of frictional heat between the slab 31 and the soft stones 32a and 32b can be at least suppressed, and the inside of the rotary grinding barrel 30 can be suppressed. In this way, the pulverized material can be pulverized efficiently with low noise without scattering the pulverized material to the surroundings.

Referring to the operation of the rotary grinding device according to the present invention as described above are as follows.

First, the driven motor 11 is operated by operating the on / off switch installed in the power transmission unit receiving cylinder 10 while the pulverized material is introduced into the rotary grinding cylinder 30 and disposed on the stone plate 31. When the power is applied to the drive motor 11 is driven while the drive motor 11 The driving force is transmitted to the rotation shaft 12b of the reducer 12 through the V-belt 12. The rotational speed of this drive motor 11 is reduced by the speed reducer 12 at low speed (150-200 rpm). As a result, the rotating plate 12 coupled to the rotating shaft 12b is rotated while the rotating shaft 12b is rotated.

As the rotary plate 21 rotates, the stone plate 31 fixed to the rotary plate 21 and the rotary grinding cylinder 30 fixed to the outer circumferential surface of the stone plate 31 are rotated together. At this time, the pulverized object on the rotating stone plate 31 is attached to the lower surface of the pair of roller-type soft stone 32a, 32b elastically fixed to the upper surface of the stone plate 31 by the fixing rod 35. As it is engaged, it is crushed by its load and friction.

At the time of pulverizing such a pulverized object, if the upper surface of the rotary pulverization cylinder 30 is covered with the cover portion 90, the pulverized substance or a part of the pulverized substance is not scattered out of the rotary pulverization cylinder 30, In addition, since the pulverized material is pulverized by the rotational frictional force as in the principle of soft magnetic mill in the sealed rotary grinding box 30, noise pollution can be minimized.

On the other hand, when the pulverized material is thus pulverized, the inner circumferential surface of the rotary pulverization cylinder 30 is also installed while being rotated together with the second scraper 39a which is installed at the lower portion of the fixed rod 35 toward the inner circumferential surface side of the rotary pulverization cylinder 30. The scraper 38a, 38b attached to the surface of the soft stone 32a, 32b is collected so as to be collected toward the soft stone 32a, 32b while scraping a part of the to-be-ground object sticking to or scraping to one side. By grinding a part of the to-be-adhered object which adhered to the surface of the soft stone 32a, 32b, and collecting it on the stone plate 31, a to-be-ground object can be grind | pulverized more evenly.

When the above grinding operation is completed, turn off the power by operating the on / off switch unit again, and opens the cover 90 installed on the upper surface of the rotary grinding barrel 30 with the hinge pin 91 as the center. . In this state, the operating lever 50 installed in a hinged manner to the vertical support piece 41a for holding the power transmission part storage container 10 and the rotary grinding cylinder 30 together, as shown in FIG. When lowered, the power transmission unit 10 and the rotary grinding barrel 30 are inclined obliquely in an upright state, and in this state, the pulverized material in the rotary grinding barrel 30 can be easily moved to a separate container. Let's do it. If you want to clean the inside of the rotary grinding barrel 30, the combination of the pressing portion 60 and the fixed rod 35, the fixed rod 35 and the vertical axis (33) in the state that the cover portion 90 is opened ), And then the soft-stones 32a and 32b are taken out of the rotary grinding wheel 30 and then released.

As described above, according to the present invention, when grinding the pulverized object such as grains, vegetables, etc. by frictional force between the stone plate rotated at low speed and the pair of roller-type soft stone fixedly arranged on the stone plate by using the principle of soft magnetic mill While minimizing the generation of frictional heat, it is possible to prevent the incorporation of stone powder into the powdered matter, and to prevent the destruction of nutrients contained in the powdered material, thereby making it possible to efficiently grind the ground material.

In addition, according to the present invention, by allowing the pulverized material to be pulverized in the rotary grinding cylinder sealed by the lid portion, there is no scattering of the pulverized object during the grinding of the grinding target in the rotary grinding cylinder to improve the surrounding environment Not only that, but also grains and vegetables can be added together and processed at once.

In addition, according to the present invention, by installing a plurality of scrapers on the lower surface of the fixed rod for fixing a pair of roller-type soft stone and the surface of the pair of roller-type soft stone, the object to be crushed toward the inside of the rotary grinding bin Since it can prevent sticking or sticking to soft stone, the to-be-processed object can be grind | pulverized evenly.
