Description

[Detailed explanation of the invention] <Industrial application field> This invention uses dry batteries to rotate the motor,
This invention relates to an electric sieve that vibrates a sieve using a crank mechanism.

<Prior art> When using this type of sieve, it is desirable to clean the sieve and sometimes the container as well by washing them with water, but if electrical parts such as batteries and motors are built into the container, washing with water may be difficult. It can't be washed with water because it may bleed. In order to eliminate such drawbacks, JP-A-61-
Publication No. 2817 describes a part of a sieve in which a switch, a battery, and a motor with an eccentric rotor fixed to the output shaft are housed in a handle that can be attached to and detached from a container, and the sieve is movably supported on a support shaft inside the container. A U-shaped rib is formed on the
A configuration is disclosed in which the eccentric shaft of the eccentric rotor described above is inserted between the ribs.

Also, instead of transmitting directly as above,
A structure in which the motor is installed substantially vertically and the sieve is oscillated via a crank is also known.

<Problems to be solved by the invention> In the above structure, it is common that there is not much play between the U-shaped ribs of the sieve and the eccentric shaft. Therefore, when reinstalling the cleaned sieve, the fitting part cannot be seen at all, so you have to do it with a hunch that this will probably be the problem. I often had to try. The same thing happened when using a crank. Therefore, this idea was developed by providing a support shaft at the lower inside of the container to which the handle is removably attached, a screw cap screwed onto the support shaft to rotatably attach the sieve, and an electric motor that attaches the sieve to the inside of the handle. This work was carried out to devise a structure for simply and easily attaching a removed sieve or handle to an electric sieve that performs reciprocating rotational motion via a crank that swings in the device.

<Means for solving the problem> In this invention, restricting ridges are formed on the inner surface of the container and the outer surface of the sieve to prevent rotation that exceeds the reciprocating rotational movement of the sieve. When fitting the sieve to the support shaft of the container, the regulating protrusions serve as a mark for the position where the sieve can be fitted, and one end of the crank has a wide slanted opening on both the top and bottom. By connecting each inclined surface to a central groove into which a crank engaging protrusion protruding from the outer surface of the sieve can be fitted, the slanted surface can be easily inserted when the sieve is attached with the handle attached to the container, or when the sieve is attached to the container. To enable successful assembly in a single operation, both when attaching a handle while attached to a cylinder.

<Example> In FIG. 1, a container 1 with both upper and lower openings has an annular aperture guide plate 2 formed on its lower inner surface. The space 3 between the outer surface of the annular throttle guide plate 2 and the lower inner surface of the container 1 is relatively large. A regulating protrusion 4a is formed on the inner surface of the container cylinder 1 in the space 3, and a relatively large notch 5 connected to the lower end of the container cylinder 1 is formed in a portion of the container cylinder 1 on the opposite side of the regulating protrusion 4a. There is. In order to arrange the support shaft 6 at the center of the container 1, a plurality of support arms 7 extending radially from the support shaft 6 are connected to the annular aperture guide plate 2. The sieve 8 fitted onto the support shaft 6 is rotatably mounted by a screw cap 11 screwed onto the end of the shaft.

When the sieve 8 is mounted as described above, the cylindrical rising portion 9 corresponding to the outer circumference of the sieve 8 fits into the space 3 described above. A crank engaging protrusion 10 is formed on the outer circumferential surface of the cylindrical rising portion 9 of the sieve 8, and two regulating protrusions are formed on the outer circumferential surface of the cylindrical rising portion 9 on the opposite side from the crank engaging protruding ridge 10. 4b, 4b are formed. The interval between the two regulating protrusions 4b, 4b is made slightly larger than the amplitude when the sieve 8 performs reciprocating rotational movement due to the rocking movement of the crank 14, which will be described later, to prevent further rotation. . Two regulating protrusions 4a, 4a are provided on the container 1 side, and one regulating protrusion 4b is provided on the sieve 8 side.
may be provided. In either case, the crank engaging protrusions 1 of the sieve 8 are controlled by the regulating protrusions 4a and 4b.
The range in which the sieve 8 can be rotated is limited, and when the sieve 8 is attached, it serves as a mark to indicate what rotational position the sieve 8 should be placed in before fitting. Second
In the straight line C in the figure, one engagement protrusion 4b is the vertical protrusion 4a.
This is the center line when it comes into contact with.

Next, the handle 12 that is detachably attached to the outer surface of the container cylinder 1 on the notch 5 side will be explained. Inside this handle 12, there is a push button switch 13a, a battery 13b,
An electric device 13 including a motor 13c, a crank 14 rocked by the electric device 13, and an elastic operating lever 15 are attached. The portion of the handle 12 facing the notch 5 of the container 1 has a relatively large opening 1.
6, and one end 1 of the crank 14 is formed in this part.
7 is coming. In order to swing the crank 14 between the two straight lines B and B in FIG. 2, an eccentric rotor 19 having an eccentric shaft 18 rotating along the locus shown by circle A in FIG. 2 is attached to the motor 13c. The shaft 18 is fitted into a cutout groove 20 formed at one end of the crank 14.

Incidentally, one end 17 of the crank 14 has a sloped opening 21 which is wide both at the top and bottom, and each sloped surface 22 is continuous with a central groove 23 into which the crank engagement protrusion 10 of the sieve 8 can be inserted. There is. Therefore, in order to attach the sieve 8 with the handle 12 attached to the container 1, regardless of the inclination of the crank 14, use the regulating protrusions 4a and 4b as guides to mount the sieve 8 roughly as shown in FIG. If the crank engaging protrusion 10 is fitted onto the support shaft 6 in the direction of the crank 1.
4, and when attaching the handle 12 with the sieve 8 attached to the container cylinder 1, the crank engaging protrusion 10 is located on the upper side of the crank 14. The opening 21 of the inclined surface is located within the opening 21 of the inclined surface. In this way, the crank engagement protrusion 10 presses the inclined surface 22 of the crank end 17, and the crank 14 rotates due to the pressing force, so that the crank engagement protrusion 10 is successfully fitted into the center groove 23.

<Effect of the invention> As is clear from the above explanation, the container 1 and the sieve 8
Since the regulating protrusions 4a and 4b are provided, the proper positioning of the sieve 8 to be assembled to the support shaft 6 or the proper correction of the orientation of the sieve 8 when attaching the handle 12 to the container cylinder 1 is reliable and easy. Further, since the upper and lower sides of the crank end portion 17 are formed with wide inclined surface openings 21, 21, the crank engaging protrusions 10 of the sieve 8 determined as described above are formed in the inclined surface openings 21 on either the upper side or the lower side. Therefore, by pushing it in as it is, the correct engagement between the crank engaging protrusion 10 of the sieve 8 and the central groove 23 of the crank 14 can be achieved.
