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

(First Embodiment) A screw 12 capable of reversible operation switching is provided from the front end to the rear end on the bottom wall of the dust storage box 11 shown in FIG.

The screw 12 is a screw shaft 1
The terminal 3 is connected to a drive device 14 having a switchable driving direction, comprising a motor and a speed reducer mounted outside the rear end wall of the box 11.

At the end of the screw shaft 13, there is provided a blade 15 which faces the end of the screw 12 and feeds in the direction opposite to the feeding direction by the screw 12.

Further, it communicates with the front of the box 11 and
In the upper part of the front end wall protruding in the direction, a lid insertion port 17 with an opening / closing lid 16 is provided.

In the lower part of the front end wall of the box 11,
A discharge port 19 with an opening / closing lid 18 for discharging dust sent out by reverse rotation of the screw 12 is provided.

With the above configuration, the lid 16 is opened and dust is injected into the box 11 from the input port 17.

When the screw 12 is driven to rotate forward by the operation of the driving device 14, the introduced dust is sent backward.

When the dust reaches the blade 15, the dust is sent back by the blade 15 toward the front end of the box 11.

Then, the dust sent by the screw 12 and the reverse dust sent by the blade 15 collide with each other and are compressed.

The dust that is pushed upward and escapes and does not accumulate does not cause cavitation due to compression.

When discharging the stored dust in the box 11,
When the lid 18 is opened and the screw 12 is driven in reverse by the operation of the driving device 14, the dust is sent forward and discharged from the discharge port 19.

As shown, the lifting device 21 is placed on the ground.
If the box 11 is installed through the, the height of the inlet 17 and the outlet 19 can be freely adjusted, and the load can be easily lifted and received by the dust collection vehicle.

(Second Embodiment) As shown in FIGS. 2 and 3, the bottom wall 31 of the dust storage box 11 has a gutter shape with both ends positioned in the front-rear direction.

Above the bottom wall 31 in the box 11, a blade 32 whose both ends face the front and rear direction as in the first embodiment.
A first screw 33 is provided.

Further, on the left and right above the first screw 33, a two-row running from the rear end of the box 11 to the middle of the front end in the feeding direction opposite to the forward driving direction of the first screw 33. A second screw 34 is provided.

The front of the box 11 communicates with the front of the box 11.
A discharge port 36 with an opening / closing lid 35 (in the illustrated case, slid in the vertical direction) is provided at a position facing the first screw 33 on the front end wall protruding from the front end wall.

Further, on both sides of the front end wall of the box 11, there are provided inlets 37 with an opening / closing lid 35.

In the drawing, reference numeral 38 denotes a driving device for the first screw 33, and reference numeral 39 denotes a driving device for the second screw 34.

With the above construction, the dust put into the box 11 from the inlet 37 is sent backward by the forward rotation of the first screw 33, and when the sent dust reaches the blade 32, the blade Box 1 by 32
1 is fed backward in the front end direction.

Then, the dust sent by the first screw 33 and the reverse dust sent by the blade 32 collide with each other and are compressed, and at the same time, are pushed upward and escaped.

The dust that has been pushed upward and escaped is sent out by the second screw 34 toward the front end of the box 11 and falls onto the first screw 33. As a result, the dust in the box 11 circulates and breaks during the circulation.

Of course, when the amount of stored dust increases, the dust is stored above the second screw 34.

When the dust in the box 11 is to be discharged, the discharge port 36 is opened, and then the first screw 33 is operated in reverse rotation to discharge the dust in the box 11.

Of course, the second screw 34 is also operated to drop (feed) the stored dust onto the first screw 33.

[0050]

The dust storage device according to the present invention is configured as described above, so that the input dust can be sent in and the stored dust can be discharged with a single screw.

Further, the dust fed by the screw and reaching the blade portion is reversely fed by the blade, so that the fed dust and the reverse dust collide with each other and are compressed.

For this reason, there is no cavitation phenomenon in the dust that is pushed upward and escapes and is stored, and smooth discharge at the time of discharge is possible.

Further, the dust can be crushed by the first screw and the second screw, and the amount of accumulated dust can be increased with the crushing.
