[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust storage device.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional dust storage device inputs dust from an input port 2 provided on a rear end side upper peripheral surface of a horizontally long box 1.

[0003] The dust introduced is sent forward by a first screw 3 in a box 1.

[0004] The dust sent to the front is
The box 1 is sent further forward by the screw 4
From the front end side in the inside, it is designed to be successively stored in the rear end direction.

[0005] The second screw 4 is provided at a position lower than the first screw 3 to increase the storage space in the box 1 from the middle to the front end.

[0006] The dust in the box 1 is discharged by opening the front outlet 5 and driving the second screw 4.

[0007]

[Problems to be Solved by the Invention] According to the above configuration, a large box that is long in the horizontal direction is used in a home or business where a large amount of dust is emitted, so that a large installation space is required. It cannot be installed in homes or small shops.

Further, since the axial length of the screw becomes longer as the size of the box increases, the box and the screw must be manufactured according to the dimensions.

For this reason, there has been a problem that the cost is significantly increased.

Therefore, the present invention is intended to make it easy to enlarge the box in accordance with the amount of dust input.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a box having a bottom wall that is gently sloped from the front end to the middle and steeply sloped from the middle to the rear end. Reversibly operable screw provided on the inside of the bottom wall with a gentle slope, and protruding forward from the front of the box
In the dust storage device comprising an inlet with an opening / closing lid provided above and below the front end wall and an outlet with an opening / closing lid, an opening is provided so that the entire upper surface of the box is open, and the opening is provided with a required number of steps. A dust storage device is characterized in that the cylindrical body is added via a suitable fixing means, and the top opening of the cylindrical body is closed by a top plate attached via the proper fixing means.

[0012]

[Function] To increase the dust storage capacity in the box,
The top plate is removed, the cylinder is added to the cylinder via the fixing means, and then the upper surface of the cylinder is closed by the top plate attached via the fixing means.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

The bottom wall 12 of the box 11 shown in FIG. 1 has a gentle slope from the front end to the middle and a steep slope from the middle to the rear end.

In addition, from the front end on the bottom wall 12 in the box 11 to the middle, a screw 13 capable of reversible operation switching is provided.
Is provided.

The screw 13 is operated reversibly by a motor 14 'in a cover 14.

Further, on the upper part of the front end wall of the box 11 (on the upper peripheral side of the front end of the screw 13), an openable / closable lid 15 is provided.
At the lower end of the front end wall of the box 11 (lower side of the front end face of the screw 13), there is provided an outlet 18 with a lid 17 which can be opened and closed.

With the above construction, the lid 15 is opened and dust is injected into the box 11 from the input port 16.

The thrown dust is sent rearward by the forward rotation of the screw 13, and the dust that moves rearward is transferred upward by a steep slope from the middle to the rear end of the bottom wall 12. Store in the upper space.

When the box 11 is filled with dust, the lid 17
Is released, and then the screw 13 is driven to rotate in the reverse direction.

Then, dust is sent out by the screw 13 and discharged from the discharge port 18.

As shown in FIGS. 1 and 2, the upper surface of the box 11 is entirely opened to provide an opening 21.
A required number of stages of the cylindrical body 22 can be added to the opening 21.

In the case of the drawing, the extension of the cylindrical body 22 to the opening 21 is provided on the flange 23 after the flange 23 projecting outward from the edge of the opening 21 and the lower edge of the cylindrical body 22 is overlapped. While the bolt 25 is inserted through the matching through-hole 24 and the nut 26 is screwed into the bolt 25 and tightened, it may be attached to the above-mentioned tightening tool using a clamp fitting outside.

Further, in the case of the drawing, the same system as that of the above-described addition of the opening 21 and the cylindrical body 22 is used for adding the cylindrical bodies 22 together.

The top opening of the cylinder 22 is closed by a top plate 27.

In the case shown in the figure, the top plate 27 is fixed to the cylindrical body 22 by inserting a bolt 25 into the through hole 24 of the overlapped flange 23 and screwing a nut 26 in place.

When the cylindrical body 22 is not added to the box 11, the opening 21 is closed by a top plate 27 attached to the box 11.

[0028]

[Effect] Since the dust storage device according to the present invention is configured as described above, in an industry where the amount of dust input is large, a cylinder is added to the opening of the box and the cylinder is formed by the top plate. The box can be enlarged by closing the upper edge opening of the body.

Therefore, it is not necessary to manufacture boxes having different dimensions, and the size of the box can be extremely easily increased on site.
