DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, the overall schematic configuration will be described with reference to FIG. A main body frame 23 is vibratably supported on the frame 21 via a frame receiving spring 22. A vibrating body base 24 is attached to the lower surface of the main body frame 23, and an upper unbalance weight 26 and a lower unbalance forming a vibrating means are attached to a vibrating body housing 25 fixed to the center of the vibrating body base 24. The weight 27 is rotatably supported. The lower unbalance weight 27 is connected to a V wheel 29 via a drive spring 28. A belt 32 is stretched between this V-wheel 29 and a V-pulley 31 connected to a motor 30 in the gantry 21. As a result, the upper unbalanced weight 26 and the lower unbalanced weight 27 are connected to the motor 30.
It is driven to rotate by and generates vibration.

The main body frame 23 is constructed by stacking a lower cylindrical frame 35, a middle cylindrical frame 36, and an upper cylindrical frame 37. The upper cylindrical frame 37 has a taper-shaped lid on the upper surface of which a raw material inlet 38 is formed. 39 is covered. These cylindrical frames 35 to 37
And the connection between the upper cylindrical frame 37 and the lid 39 are substantially V-shaped in cross section.

Is obtained by bending angle steel 46a into an annular shape and welding both ends thereof. Sieve mesh 43 with this frame 46
As shown in FIG. 1, the upper arm part of the frame 46, the lower
A lower flap formed on the upper end of the middle cylindrical frame 36, which is a cylindrical frame.
Lower end of the upper cylinder frame 37, which is the upper cylinder frame
Packing 47 between the upper flange 37a welded to
In the state of being sandwiched via 48, the flange 36a,
A band 41 having a substantially V-shaped cross section is fastened and fixed to 37a. The lower piece of the frame 46 is the middle cylindrical frame 36.
It is located on the upper part of the inner circumference of the
Corresponds to the wall portion in the present invention.

As shown in FIG. 4, this band 41 has two bands.
The semi-circular V-bands 41a and 41b are combined, and the two semi-circular V-bands 41a and 41b are connected by tightening nuts 50a and 50b on bolts 49a and 49b. In this case, the bolts 49a and 49b are rotatably attached to the ends of the semi-circular V bands 41a and 41b through the pins 51a and 51b in the direction of arrow B, and the bolts 49a and 49b are attached to the semi-circular V bands.
Nut receiving portion 5 provided at the ends of the bands 41a and 41b
These bolts 49 are aligned with 3a and 53b.
By tightening the nuts 50a and 50b into a and 49b,
Both semi-circular V bands 41a and 41b are fastened.

As shown in FIGS. 1 and 2, a large number of tapping rubber balls 54 are placed on the sieve net 43 horizontally mounted in the main body frame 23 in this manner. The raw material powder is efficiently sieved while preventing clogging of the screen 43 by utilizing vibration. In addition, the upper cylindrical frame 37 is located at the lower part of the peripheral wall.
Then, a rectangular net discharge port 55 for discharging the particulate matter remaining on the sieve net 43 is formed, and a net discharge port body 56 is attached to the mesh discharge port 55 by welding or the like.
A stopper rod 57 for horizontally preventing the tapping rubber balls 54 from flowing out is horizontally fixed near the center of the net discharge port 55.

Also, a semi-circular V band 41a which is fastened to the flanges 36a and 37a below the net outlet 56.
As shown in FIGS. 4 and 5, a notch portion 58 for escaping the on-mesh discharge body 56 is formed on the outer peripheral portion of the net, and a reinforcing metal member 59 is joined to the peripheral portion of the notch portion 58 by welding or the like. . As shown in FIG. 1, a packing 60 is also interposed between the upper end flange 37b of the upper cylindrical frame 37 and the flange 39a of the lid 39, and the packing 60 is welded to the inner circumference of the upper end of the upper cylindrical frame 37. It is positioned and held by a packing stopper 61.

In the vibrating screen device configured as described above, when the screen screen 43 is removed for replacement or cleaning of the screen screen 43, first, the middle cylindrical frame 36 and the upper cylindrical frame 37 are connected and fixed. The nuts 50a and 50b are removed (or loosened) from the bolts 49a and 49b of the band 41, and the band 41 is removed to make the upper cylindrical frame 37 removable. After that, if the upper cylindrical frame 37 is removed from the middle cylindrical frame 36, the sieve net 43 with the frame 46 is removed.
It is in a state of simply riding on the lower flange 36a. In this state, removing and removing the screen 43 does not require any bolt removal as in the prior art, and the screen 43 can be removed with one touch.
Can be removed. Therefore, replacement and cleaning of the screen 43 can be performed very easily. Moreover, the flavor
The lower piece of the drum 46 is located above the inner peripheral portion of the middle cylindrical frame 36.
In this manner, the upper piece part has a middle cylindrical frame 36 and an upper cylindrical frame 37.
It is sandwiched between and attached to the body frame 23.
So, when sieving the raw material powder,
It is extremely important that the product powder gets between the 46 and the body frame 23.
Power can be prevented. In addition, the middle cylindrical frame 36 and the upper cylindrical frame 37
A notch 58 is formed in the band 41 for fastening and fixing.
Since it is installed, it is discharged onto the net on the lower part of the peripheral wall of the upper cylindrical frame 37.
Even if the mouth 55 is formed, the on-mesh outlet 56 is removed without any inconvenience.
Can be attached, and the position of the formation position of the on-mesh outlet 55 can be adjusted.
There is no need to make a joint, and the band 41 is further reinforced.
By providing 59, the tightening strength may be reduced.
Can be prevented.

In the first embodiment, the tapping rubber balls 54 are placed on the sieve net 43. However, as in the second embodiment of the present invention shown in FIG. A ball receiver 71 made of a perforated plate may be sandwiched and fixed via a U packing 72 between the flange 36b and the flange 35a of the lower cylindrical frame 35, and a tapping rubber ball 54 may be placed on the ball receiver 71. .

Further, in the first and second embodiments described above,
Although the main body frame 23 is configured by stacking the cylindrical frames 35 to 37 in three stages, the cylindrical frames may be stacked in two stages or four or more stages. Further, in the case where the cylindrical frame has three or more stages, a screen mesh having different meshes may be sandwiched in each stage of the cylindrical frame to provide a plurality of screen screens in the main frame.

In addition, the present invention provides a tapping rubber ball 54.
Or the ball receiver 71 may be omitted, or the band 41
The tightening method may be changed, and various changes can be made without departing from the spirit of the invention.
