  Next, dust storage and discharge operations by the dust storage and discharge device configured as described above will be described.

  First, the input lid 66 is opened and dust is introduced into the bottom of the conveyance path 61 through the input port 67 and the chute 68. The thrown dust is transported upward by the circulating movement of the transport plate 62 and is thrown into the throwing tank 2 through the upper surface opening.

  The dust thrown into the charging tank 2 in this way is conveyed and stored from the charging tank 2 to the storage tank 3 through the bottom by the rotational drive of the conveying screw 4 arranged at the storage position (see FIG. 4).

  By sequentially performing this operation, dust is gradually stored in the storage tank 3, and when the storage tank 3 is filled with dust to some extent, it is stored by the weight of the entire dust and the pushing action of the dust by the conveying screw 4. The dust is stored in the tank 3 while being compressed (see FIG. 5).

  Thus, by storing the dust in the storage tank 3 while being compressed by the pushing action of the conveying screw 4, the compression efficiency of the dust can be increased, and the dust can be efficiently stored.

  In addition, since the dust is transported upward from the bottom of the transport path 61 and thrown into the storage tank 3, the position of the throwing port 67 of the throwing portion 65 can be made as low as possible. It becomes easy and can cope with barrier-free.

  The dust throwing device 6 and the conveying screw 4 may be operated intermittently in conjunction with, for example, the opening / closing operation of the charging lid 66, or may be operated for a predetermined time by a switch operation. You may make it operate | move continuously as needed.

  When discharging the dust stored in the storage tank 3 as described above, the discharge lid 53 is opened, and the conveying screw 4 is slid from the storage position to the discharge position by the slide mechanism. The dust is sequentially discharged to the outside from the discharge port 51 by the rotational driving of the conveying screw 4 (see FIG. 6).

  At this time, for example, as shown in FIG. 1, the discharge port 51 is provided with an input port of the garbage collection vehicle, so that the dust collection vehicle can easily accommodate the dust in the storage tank 3, and can be stored in a treatment plant or the like. Can be transported. That is, the height position and the like of the discharge port 51 may be set so as to easily accommodate the dust according to the transport vehicle that transports the dust.

  When storing the dust in this way, the bottom space on the discharge portion 5 side of the storage tank 3 where the transport screw 4 is not disposed is used as the dust storage space by arranging the transport screw 4 at the storage position. Thus, a large storage volume of dust can be secured, and dust can be efficiently stored in combination with the compression action described above.

  In addition, when discharging the dust, the conveying screw 4 is slid from the storage position to the discharge position so that the dust stored in the storage tank 3 can be forcibly moved by this sliding operation. Even if the phenomenon occurs, it can be canceled and the dust in the storage tank 3 can be discharged smoothly.

  In addition, when the dust is fully stored in the storage tank 3, it is necessary to prohibit the addition of the dust more than this. As this means, for example, the opening / closing frequency of the closing lid 66 is counted, and when the predetermined number of times is reached, the closing lid 66 is locked in a closed state to prohibit the opening. That is, since the total input amount can be estimated from the amount of dust that can be input by opening the input lid 66 once, the input lid that will reach the full amount by comparing it with the storage volume of the storage tank 3. 66 times of opening and closing may be set. Further, the full amount of dust may be detected based on the load acting on the drive motor 43 that drives the conveying screw 4, and the full amount may be detected by other means such as a level meter. .
