a is provided in the through hole 33a, and a notch 33b is provided in the through hole 33a.
is provided in the axial direction in accordance with the locking protrusion 23a. This allows the boss portion 33 to enter into the locking protrusion 23a, and the mesh body 7 is detachably attached to the support shaft 23. Further, when the mesh body 7 is attached to the support shaft 23, the locking portion 39 engages with the locked portion 21 of the container body 3 and is prevented from rotating.

A detachable member 9 is attached to the lower end of the support shaft 23 on which the net 7 is supported. The detachable member 9
a small diameter portion 43 into which the support shaft 23 is inserted;
A knob portion 45 located at the lower end of the small diameter portion 43 is integrally molded. A locking groove 43a is formed on the outer periphery of the upper end of the small diameter portion 43 so as to extend in the axial direction in accordance with the locking protrusion 23a. Further, a stepped portion 43b is formed on the outer periphery of the upper end of the small diameter portion 43, and a locking spring 47 is attached to the stepped portion 43b. When attaching the removable member 9 to the support shaft 23, this latch spring 47 expands in diameter while slidingly contacting the latch protrusion 23a located in the latch groove 43a, and after passing over the latch protrusion 23a, the latch spring 47 becomes elastic. It returns and latches with the latching protrusion 23a.

A gripping portion 13 is provided on the outer periphery of the container body 3 with external teeth 2.
It is detachably attached at a position corresponding to 9a. A hook portion 51 is integrally formed at the lower end of the case 49 of the grip portion 13 so as to extend upward as shown in the figure. The hook portion 51 is hooked to the inner surface of the container body 3 via an opening 53 provided at the lower end of the container body 3. Further, an attachment/detachment button 55 is attached to the upper end of the case 49 so as to be movable up and down through an opening 57a. This detachable button 55
A compression spring 57 is installed between the housing 49 and the case 49, and the elastic force of the compression spring 57 always urges the attachment/detachment button 55 upward. Further, a claw portion 59 facing upward is integrally formed on the left end portion of the attachment/detachment button 55. The claw portion 59 engages with an engagement hole 24 integrally formed on the upper outer peripheral surface of the container body 3.
Further, the case 49 has an electric motor 11 built therein. The rotating shaft 11a of the electric motor 11 is connected to the external teeth 29a via a speed reduction mechanism 63. This speed reduction mechanism 63 includes a first gear 65 fixed to the rotating shaft 11a, a second gear 67 that meshes with the first gear 65, a third gear 69 integrally molded with the second gear 67, and a third gear 69 that is integrally formed with the second gear 67. A fourth gear 71 that meshes with the gear 69, and an external tooth 2 that is integrally molded with the fourth gear 71.
9a and a fifth gear 73 that meshes with the gear 9a. In the figure, 75 is a power switch, and 77 is a battery housed in the case 49.

Next, the electric sieve device 1 configured as described above
The operation will be explained with reference to FIGS. 2 and 3.

2 and 3, when the boss portion 25 of the rotating body 5 is inserted into the support shaft 23, the notch 25b
Since the rotating body 5 is allowed to enter the latching protrusion 23a, the rotating body 5 is rotatably supported with respect to the support shaft 23. Further, when the boss portion 33 of the mesh body 7 is inserted into the support shaft 23 to which the rotating body 5 is attached as described above, the notch 33b engages the latch protrusion 23a.
Since the mesh body 7 is allowed to enter the support shaft 23
Supported by At this time, the locking portion 39 and the locked portion 21 engage with each other, and the mesh body 7 is prevented from rotating. Next, the small diameter portion 43 of the detachable member 9 is attached to the latch protrusion 23a with respect to the support shaft 23 to which the rotating body 5 and the net body 7 are attached.
When inserted so that the latching groove 43a and the latching groove 43a are aligned with each other, the latching spring 47 expands in diameter against the elastic force of the latching protrusion 23a while slidingly contacting the latching protrusion 23a.
After passing over this, the diameter is reduced by the elastic force and is latched onto the latching protrusion 23a. This prevents the rotating body 5 and the mesh body 7 from coming off from the support shaft 23.

In the above state, with the hook part 51 hooked to the inner surface of the container main body 3 through the opening 53, the upper end of the grip part 13 is positioned on the container main body 3 side while pressing the attachment/detachment button 55. The claw portion 59 is connected to the engagement hole 2.
4, when the press of the attachment/detachment button 55 is released, the attachment/detachment button 55 is moved upward by the elastic force of the compression spring 57, and the claw portion 59 is engaged with the engagement hole 24. At this time, the fifth gear 73 is connected to the external tooth 29a.

When the power switch 75 is turned on after the powder material to be sieved is put into the container body 3, the driving force of the electric motor 11 is changed to the first to fifth stages.
Since it is applied to the external teeth 29a via the gears 65 to 73, the rotating body 5 is rotated at a rotation speed of a required reduction ratio with respect to the rotation speed of the electric motor 11. As a result, the powdered material introduced into the container body 3 as the rotating body 5 rotates is sieved while being stirred by the crushing member 31 and the ribs 27. At this time, fine-sized powder solidified by moisture or the like is embedded in the ribs 27 and the inclined surfaces of the crushing member 31 and pressed against the net 7, thereby being crushed and sieved. Similarly, if a powdery substance hardens to a size larger than the distance between the mesh body 7 and the ribs 15 due to moisture, etc., the ribs 15 prevent it from moving together with the rotating ribs 27 and the crushing member 31. be done. When the ribs 27 and the crushing member 31 pass under the powdery material whose movement is regulated, the powdery material is finely crushed by large vibration printing, and then the ribs 27 and the crushing member 31 pass under the powdery material whose movement is regulated. It is sieved while being crushed by the inclined surface of 31.

In this manner, in this embodiment, the powder particles can be sieved while being crushed by the rotating body 5 rotating above the net 7. Also,
Since the net 7 is replaceably attached to the support shaft 23 via the detachable member 9, the net can be easily replaced depending on the powder to be sieved.

In the above description, the rotary body 5 and the mesh body 7 are each attached to the support shaft 23 in a replaceable manner using the detachable member 11.
The mesh body 7 is made non-removable by a ring etc.
It may be made detachable by the attaching/detachable member 11.
