Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial field of application] This invention aims at removing wheat flour so that it can be cooked in an optimum state by eliminating the lumps of wheat flour that are easily formed when dissolved in water or the like. The present invention relates to the structure of a sieve in a powder sieving machine which is used in the case where it is separated by sieving and is brought into contact with air to make the density of wheat flour uniform.

[Conventional technology]

Conventionally, as a powder sieving machine of this type, for example, Shoukaisho 60-9
There is one shown in Japanese Patent No. 4143. In this powder sieving machine, a coarse mesh net and a fine mesh net are fixed to the upper and lower end surfaces of the intermediate ring, and rotary blades are respectively supported on these mesh nets.

[Problems to be solved by the device]

However, in the above-mentioned sieve, since the upper and lower both strain nets are integrated with the intermediate ring, there is a drawback that it is difficult to clean the both strain nets.

An object of the present invention is to facilitate cleaning of a fine mesh screen particularly in a sieve having a coarse mesh screen and a fine mesh screen.

Constitution of the Invention [Means for Solving the Problems] In view of this object, the powder sieving machine according to the present invention has a rough surface on a sieve support portion 8 provided at the bottom of the container 1 as shown in the drawings of the embodiments described later. Rotating support parts 14, 19, 25 for supporting the strainer net 12 and rotatably supporting the fine strainer mesh 13 on the lower side of the rough strainer mesh 12 are provided. The rotation supporting portions 14, 19, 25 are provided with locking portions 27, 28 that allow the fine mesh net 13 to be attached to and detached from the coarse mesh net 12 according to the rotation.

[Action]

Now, when the fine mesh net 13 is rotated with respect to the coarse mesh net 12, the locking portions 27 and 28 are disengaged from each other, and the fine mesh net 13
Only the mesh can be removed from the coarse mesh net 12 for cleaning. After the cleaning, the fine mesh net 13 is attached to the coarse mesh net 12 by a procedure reverse to the above-described disassembling procedure.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the container 1 is composed of a cylindrical storage cylinder portion 2 having a charging port 2a at the upper end thereof, and a handle 3 integrally formed on the outside of the storage cylinder portion 2. The handle 3 includes support arms 4a and 4b extending from the outside of both upper and lower end portions of the storage cylinder portion 2 and a handle portion 5 assembled between the upper and lower support arms 4a and 4b. A flange 6 is projectingly provided on the inner circumference of the lower end portion which is the bottom of the storage tubular portion 2, and ribs 7 are provided between both sides of the flange 6.
A sieve support 8 is formed at the center of the storage cylinder 2. A male screw 9 is provided on the supporting portion 8 so as to project downward. A drop port 10 is formed between the inner peripheral edge of the flange 6 and the rib 7.

The sieve 11 comprises a coarse mesh net 12 and a fine mesh net 13. First
As shown in Figs. 5 and 6, for the coarse mesh net 12, its peripheral wall 1
A mesh body 16 is stretched between the inner periphery of 4 and a mounting cylinder 15 at the center of the peripheral wall 14. A support cylinder 17 is provided in the mounting cylinder 15.
Are integrally formed via four elastic arms 18. Perimeter wall 14
A support wall 19 extending along the peripheral wall 14 is provided on both sides of the lower end of the support wall 19 so as to project downward, and an interlocking arm 20 extends laterally from the lower end of one support wall 19. An interlocking hole is provided at the tip of the interlocking arm 20.
21 are formed. As shown in FIGS. 1 and 2, the coarse mesh net 12 is inserted into the bottom of the storage cylinder 2 from below the flange 6 and the rib 7 of the storage cylinder 2, and the sieve support 8 is inserted.
The male screw 9 is inserted into the support cylinder 17, and the interlocking arm 20 faces the lower surface of the lower support arm 4b of the handle 3.
A nut 22 is screwed onto the male screw 9, and a support cylinder 17 is attached between the sieve support portion 8 and the nut 22. The peripheral wall 14 is located below the flange 6, and the outer periphery of the net body 16 abuts on the lower edge of the flange 6 so that the drop port 10 is closed by the net body 16. An electric motor (not shown) is built in the grip portion 5 of the handle 3, and an eccentric cam 24 attached to a rotary shaft 23 of the electric motor is inserted into an interlocking hole 21 of the interlocking arm 20.

On the other hand, for the fine mesh net 13 as shown in FIGS.
A mesh 26 is stretched inside the peripheral wall 25, and locking projections 27 are formed on both outer peripheral sides of the peripheral wall 25 so as to extend in the circumferential direction. First,
As shown in FIG. 2, the fine mesh net 13 is the coarse mesh 12
The peripheral walls 14 and 25 of the coarse mesh net 12 are abutted against each other inside the support walls 19 of the coarse mesh net 12 and the peripheral wall of the fine mesh net 13 extends along the inner surface of the support walls 19. 25 is in sliding contact. Locking grooves 28 are formed inside the both support walls 19 so as to extend in the circumferential direction, and the locking projections 27 of the fine mesh net 13 are formed.
Are inserted in the locking groove 28. Net of fine mesh strainer 13
Since 26 is pushed downward by the nut 22, the third
As shown in the figure, with the locking projection 27 inserted in the locking groove 28, the locking projections 27a, 28a engage with each other and the fine mesh net 13 is positioned with respect to the coarse mesh net 12. It has become so.

When the eccentric cam 24 of the rotary shaft 23 rotates, the interlocking arm 20
Vibrates in the horizontal direction orthogonal to the axis of the coaxial shaft 23, and the coarse mesh net 12 and the fine mesh net 13 vibrate integrally. The mounting cylinder 15 at the center of the coarse mesh net 12 vibrates in the horizontal direction orthogonal to the axis of the male screw 9 supporting the support cylinder 17 against the elastic force of each elastic arm 18.

When cleaning the sieve 11 composed of the coarse mesh net 12 and the fine mesh net 13 in this way, by pressing the fine mesh net 13 upward, both the locking projections 27 and the coarse mesh strainer 13 of the fine mesh net 13 are pressed. In both locking grooves 28 of the net 12, the locking protrusions 27a, 28a are disengaged from each other. When the fine mesh net 13 is rotated with respect to the coarse mesh net 12 as shown in FIG.
It is possible to remove the fine mesh strainer net 13 only from the coarse mesh strainer net 12 downward. In addition, attach the nut 22 to the male screw 9
Remove the rough mesh net 12 and pull it downward to remove the rough mesh net.
When the 12 support cylinders 17 come off the male screw 9, the eccentric cam
24 is disengaged from the interlocking hole 21, and the coarse mesh net 12 can also be detached downward. In this way, both strainer nets 12, 13 separated from the container 1 are washed. After washing, the both strainer nets 12 and 13 are assembled in the reverse order of the disassembly procedure described above.

In particular, in the sieve 11 of the powder sieving machine according to the present embodiment, the fine mesh screen 13 can be easily attached / detached by simply rotating the fine mesh screen 13 with respect to the coarse mesh net 12, so cleaning of the fine mesh net 13 is difficult. It will be easier to do.

Further, since the coarse mesh net 12 can be easily attached to and detached from the container 1 only by attaching or detaching the nut 22 to or from the male screw 9, the coarse mesh net 12 can be easily washed.

Effect of the Invention According to the sieve 11 of the powder sieving machine according to the present invention, the fine mesh screen 13 can be easily attached and detached by rotating the fine mesh screen 13 with respect to the coarse mesh net 12, so that the fine mesh screen 13 can be cleaned. Very easy to do.
