Description

GRAIN FILTER

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain filter, and more particularly, to a grain filter capable of finely lowering grains or increasing work efficiency for filtering foreign matter contained in grains.

Generally, during the preparation process of baking, the sorting process is carried out in which the flour, which has a certain size, is rolled into fine particles.

In addition, during the screening operation, a work for filtering foreign matter contained in flour is also performed.

Hereinafter, a conventional grain filter will be described with reference to FIG.

As shown in the drawing, the conventional grain filter has a collecting container 10 in which cereal flour is contained, a collecting container 20 installed at the upper end of the collecting container 10 and selectively passing only fine particles of the grain powder .

However, in the sorting operation using the grain filter according to the related art, when a large amount of grain powder is placed on the collecting mold 20, the operator holds the collecting mold 20 with one hand and shakes it in the left- There is a complicated operation of pushing the grain powder directly with the palm and passing it through the collection frame 20 and inconvenience to take.

In addition, in the process of swinging the harvester frame 20 in the left and right direction, some of the grain powder that has passed through the harvesting frame 20 frequently deviates to the outside of the collecting container, and thus the vicinity of the work site becomes dirty.

FIG. 5 is a perspective view showing the coupling structure and operation of the auxiliary lever, which can be flexibly and flexibly adjusted in accordance with the size of the collection container, in FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 to 5 attached hereto.

As shown in the figure, the grain filter according to the present invention includes a collecting container 100 having a receiving space part 101 with an open upper part, a filtering operating part 200 And a filtration body 300 formed in the filtration operation means 200 and having a porous body 301 and a sieve 301 for filtering a grain powder and foreign matter having a predetermined size or more.

First, the collecting container 100 collects the grain powder (wheat flour, rice flour, soybean flour, etc.) in one place in an open top shape with a depressed depressed shape.

In addition, a holding handle (not shown) may be formed on one side of the outer peripheral surface of the collecting container 100.

The filtration operating means 200 is installed on the open upper portion of the collecting container 100 and is an operating mechanism that allows only fine particles among various sizes of grain powder to be filtered.

Specifically, the filtration operation means 200 includes a fixed unit 210 installed on one side and the other side of the collecting container 100, respectively, one end in the longitudinal direction is coupled to the fixed unit 210, An operation unit 220 that linearly moves in the left and right direction with respect to the unit 210 and a holder unit 220 which is formed at one point in the longitudinal direction of the operation unit 220 and accommodates the filter body 300 to be described later 230).

The fixed unit 210 includes a first fixed supporting portion 211 coupled to one side of the frame of the collecting container 100 and a second fixed supporting portion 212 coupled to the other side facing the first fixed supporting portion 211, .

Coupling grooves 211a and 212a are formed in the lower portions of the first and second fixed support portions 211 and 212 to correspond to the cross-sectional thickness of the collecting container 100.

It is preferable that the first and second fixed support portions 211 and 212 are made of synthetic resin capable of elastic deformation.

This is to enable easy coupling in correspondence with the cross-sectional thickness or radius size of the collection container 100.

In addition, at least one pressing protrusion 211b, 212b may be additionally formed on the inner surface of the coupling groove 211a, 212a.

The pressing protrusions 211b and 212b further improve the tight coupling force between the coupling grooves 211a and 212a and the collecting container 100.

A coupling projection 211c having a predetermined height is formed on the upper portion of the first fixed support portion 211 and a moving range of the operation unit 220 in the left and right direction is regulated on the upper portion of the second fixed support portion 212 A guide member 212c is formed.

Of course, the second fixed support portion 212 has a longer shape than the first fixed support portion 211 so that the operation unit 220 can be linearly moved in the left-right direction.

As shown in FIG. 4, the guide member 212c may be provided with an elevation guide groove 212d for guiding the operation unit 220 to move up and down.

This is to allow the operation unit 220 to move not only in the lateral direction but also in the vertical direction.

That is, the operation unit 220 vibrates the filter member 300 due to impact energy applied to both sides of the guide member 212c and the elevation guide groove 212d in the process of moving in the left-right direction and the up-down direction The grain powder contained therein is subjected to a sorting operation through the feed 301.

In addition, rubber pads 212e are additionally attached to both longitudinal ends of the guide member 212c.

This is because it is possible to minimize the damage of the guide member 212c or the operation unit 220 or the occurrence of the impact noise due to the impact that the operation unit 220 hits.

5, a coupling hole 221 is formed at one end in the longitudinal direction of the operation unit 220 in correspondence with the coupling protrusion 211c, and an auxiliary lever 222 is hinged at the other end. .

That is, the auxiliary lever 222 can adjust the length of the operation unit 220 in accordance with the size of the collecting container 100 in a stretchable manner.

In other words, the auxiliary lever 222 is hinged to the other end of the operation unit 220 and hinges in a folding or unfolding direction about the hinge pin.

Meanwhile, the filtration body 300 is formed in the filtration operation means 200, and is a mesh member for filtering the grain powder and foreign matter of a predetermined size or more.

The filtration body 300 according to the present invention is formed into a cylindrical shape having a certain width and height.

That is, the filtration body 300 not only allows the grain powder to pass through the bottom surface but also allows the grain powder to pass through in the circumferential direction having a height, thereby further improving the efficiency of the sorting operation.

In addition, since the filtration body 300 is located in the space portion close to the center portion of the collection vessel 100, the grain powder passing through the filtration body 300 flows out toward the collection vessel 100, It can be prevented from being canceled.

In addition, the filtration body 300 and the filtration operation means 200 can be formed as an assembly structure capable of mutually attaching and detaching.

A locking step 231 is formed on the inner circumference of the holder 230 of the filtration operation means 200 and a locking protrusion 310 interfering with the locking step 231 is formed on the filtration body 300. [ .

According to the present invention constructed as described above, the filtration operating means 200 provided on the opened upper portion of the collection container 100 and the filtration body 300 formed on the filtration operation means 200 make the grain powder It is possible to quickly and easily perform the sorting operation to pass through the filter 301 and to prevent the grain powder passing through the filtration unit 300 from flowing out toward the collecting container 100 and preventing the periphery from becoming dirty There is an effect that can be.
