  The weight 35 is kept in balance with the weight on the bag body support member 11 side until the dust bag 33 is filled with a predetermined amount of dust 33 (until the bag body 18 reaches a predetermined weight). The weight is set so that the main body 12 of the bag support member 11 is kept in a horizontal state. When the dust 33 is packed in the bag body 18 to a predetermined amount or more and the weight of the bag body 18 exceeds the predetermined weight, the main body 12 of the bag body support member 11 rotates downward about the hinge 16. The bag body 18 slides downward along the support rod 15 and the bottom plate 13 of the main body 12 of the bag body supporting member 11, and the bag body 18 is discharged from the main body 12 of the bag body supporting member 11.

  The mounting portion 10 of the gantry 2 is provided with detection means 26 such as a limit switch for detecting the vertical position of the weight 25. By detecting the vertical position of the weight 25 by the detection means 26, it is possible to detect whether the main body 12 of the bag support member 11 is in a horizontal state or in an inclined state. That is, it is possible to detect whether the bag 18 is attached to the main body 12 or is discharged from the main body 12. The detection result by the detection means 26 is transmitted to a management room (not shown) by wire or wirelessly, and the state of the main body 12 of the bag body support member 11, that is, the state where the bag body 18 is attached to the gantry 2 in the management room. Or whether it is discharged from the gantry 2 is managed.

Next, the operation of the dust collecting apparatus 1 of the present embodiment configured as described above will be described.
First, as shown in FIG. 1, two bag bodies 18 are prepared, and the two bag bodies 18 are inserted by inserting the support rod 15 of the main body 12 of the bag body support member 11 into the insertion portion 20 of each bag body 18. Is attached to the main body 12. In FIG. 1, two bag bodies 18 are attached to the main body 12, but three or more bag bodies 18 may be attached to the main body 12.

  In this case, by sliding the insertion portion 20 of each bag body 18 along the support rod 15, the bag body (second bag body 18 b) on the back side (left side in FIG. 1) keeps the opening portion 19 closed. The first bag body (first bag body 18a) on the front side (right side in FIG. 1) has the opening 19 open, and the opening 19 of the first bag body 18a is positioned below the conveying end of the conveyor 32.

  Then, the dust 33 adhering to the screen is lifted up by a rake and discharged to the upper portion of the conveyor 32. By driving the conveyor 32, the dust 33 is conveyed to the right in FIG. 1, and the dust 33 is moved from the conveying end of the conveyor 32. It is dropped in the dust accumulation part 34 and packed into the first bag body 18 a attached to the bag body support member 11 through the opening 19. And the garbage 33 is conveyed continuously or intermittently with the conveyor 32, and the predetermined amount of garbage 33 is packed in the 1st bag body 18a.

Then, when a predetermined amount of dust 33 is packed inside the first bag body 18a and the weight of the first bag body 18a reaches a predetermined weight, the weight on the bag body support member 11 side is limited as shown in FIG. By becoming heavier than the weight of the weight 25 of the member 22, the equilibrium state between the weight on the bag body supporting member 11 side and the weight of the weight 25 is broken, and the weight 25 moves upward via the rope. As a result, the main body 12 of the bag body supporting member 11 is rotated downward about the hinge 16 to be inclined, and the first bag body 18a is attached to the support bar 15 and the bottom plate 13 of the main body 12 of the bag body supporting member 11. The first bag body 18a is released from the gantry 2 and dropped onto the bottom of the dust accumulation part 34.
When the first bag body 18a is discharged from the main body 12, the weight 25 moves downward due to its own weight, and the weight of the weight 25 and the weight on the bag body supporting member 11 return to an equilibrium state. The main body 12 of the support member 11 returns to the horizontal state.

  In this case, the first bag body 18a is connected to the vertical member 8 of the gantry 2 by the support rope 21 and is slid from the main body 12 while being supported by the support rope 21 so that the opening 19 faces upward. As it is, it is discharged from the gantry 2 to the dust collecting portion 34, and the dust 33 does not jump out from the opening 19. When the first first bag body 18a is discharged, the second second bag body 18b is automatically set.

  Further, when the detection means 26 detects that the first bag 18a is discharged from the main body 12 of the bag support member 11 and the weight 25 of the limiting member 22 has moved upward, the detection signal is transmitted to the management room, It can be confirmed that the first bag 18a is discharged from the bag support member 11 in the management room.

  After the first first bag body 18a is discharged, the second second bag body 18b is automatically set, but the third and subsequent bag bodies 18 are not set. It is necessary to set the third and subsequent bags 18 until the second bag 18b of the second sheet is set and the second bag 18b is filled with dust.

  In this way, by filling the first bag body 18a and the second bag body 18b with a predetermined amount of dust 33, the dust 33 conveyed by the conveyor 32 can be continuously collected.

  In addition, when packing of the garbage 33 into the 1st bag body 18a and the 2nd bag body 18b is completed, the 3rd bag body and the 4th bag body which are next to the bag body support member 11 are mounted | worn with respect to these Thus, the dust bags 33 are packed in the same manner as the first bag body 18a and the second bag body 18b, and the dust bags 33 are continuously packed in the bag body 18.

  In the dust collecting apparatus 1 of the present embodiment configured as described above, the dust 33 conveyed from the conveyor 32 is dropped into the dust collecting portion 34 while being packed in the bag body 18, and the collecting portion Since each bag body 18 is discharged from 34, the dust 33 is not stacked in the dust stacking portion 34 in a pile. Therefore, a part of the dust 33 accumulated in the dust collecting part 34 is not drawn into the conveyor 32, and the conveyor 32 is not overloaded and breaks down. Can be maintained.

  In addition, since the operator does not need to pack the dust 33 collected in the dust collecting unit 34 into the bag 18 using a scoop or fork, the dust 33 can be collected easily and efficiently. it can.

  Furthermore, since the gantry 2 is installed in the dust accumulation part 34, and the bag body supporting member 11 and the limiting member 22 are attached to the gantry 2, the equipment cost can be reduced.

  FIG. 3 shows a second embodiment of the dust collecting apparatus 1 according to the present invention. In the dust collecting apparatus 1 of the present embodiment, a plurality of tension springs 27 having hooks 28 provided at the tips are attached downward to the bag body mounting portion 3 of the gantry 2 as the bag body support member 11. The bag body 18 is configured to be mounted on the bag body mounting portion 3 by hooking the edge of the opening 19 of the bag body 18 on the hook 28 of 27.

  As the tension spring 27 is filled with a predetermined amount of dust 33 inside the bag body 18 and the bag body 18 reaches a predetermined weight, the tension spring 27 is deformed in an extending direction and the hook 28 extends. It is set so as to be deformed to be detached from the opening 19 of the bag body 18. As a result, the bag body 18 can be dropped onto the bottom of the dust stacking portion 34 with the opening 19 facing upward by filling the bag body 18 with a predetermined amount of dust 33.

  In this case, the gantry 2 is provided with detection means 26 such as a limit switch for detecting the vertical position of any of the tension springs 27, and by detecting the extension of the tension spring 27 with the detection means 26, It can be detected that the bag 18 is detached from the tension spring 27. The detection signal by the detection means 26 is transmitted to the management room by wire or wirelessly, and by confirming the detection signal in the management room, a predetermined amount of dust 33 is packed inside the bag body 18 and the bag body 18 accumulates dust. It can be confirmed that it has been dropped to the bottom of the portion 34.

  And even if it exists in the dust collection apparatus 1 of this Embodiment, there exists an effect similar to what is shown in the said 1st Embodiment.

  In each of the above embodiments, the dust collecting device 1 according to the present invention is mechanically lifted from the screen by the rake with the dust 33 attached to the screen installed so as to close the intake port of the hydroelectric power plant. In addition, the present invention has been applied to the dust collecting device 31 that transports and accumulates the dust collecting unit 34 installed at a position away from the water intake port etc. by the conveyor 32 as the transport means, but other various dusts are transported by the transport means such as the conveyor.
