The rear end opening of the tank 3 can be opened or closed.

  Next, the operation of the suction pump 1 configured as described above will be described.

  First, when a dry-type collected material such as powder is collected and discharged, a suction pipe (not shown) is connected to the suction pipe 7 and extends to a position where the suction-collected material is sucked. Next, when the on-off valves 181, 182, 161, 163, 261, 262 are closed and the on-off valves 142, 191, 192, 171 are opened and the blower 10 is driven, the suction port is connected to the pressure-increasing / decreasing pipe 14, The cyclone dust collector 12 and the bag filter 15 communicate with the receiver tank 3, and the discharge port communicates with the atmosphere via the discharge pipe 17 and the cyclone dust collector 11.

  Thereby, since the blower 10 sucks the air in the receiver tank 3 and discharges it to the atmosphere, it is possible to make the pressure in the receiver tank 3 negative. When the pressure in the receiver tank 3 falls below a certain level, the on-off valve 71 is opened, and the dry-type collected material is sucked and collected in the receiver tank 3 through the suction pipe and the suction pipe 7.

The air is sucked and the inside is maintained at a negative pressure. Thereafter, if the on-off valve 71 is opened, the wet collected material is sucked and collected in the receiver tank 3 through the suction pipe and the suction pipe 7.

  A part of the wet recovered material collected in the receiver tank 3 through the pressure increasing / decreasing pipe 14 is sucked to the blower 10 side, and the wet recovered material is collected by the cyclone type dust collector 12.

  In this way, when the wet collection material is sucked and collected in the receiver tank 3 and reaches a certain amount, the suction collection operation of the wet collection material is stopped and returned to the running state. Then, after moving the suction pump 1 to the discharge place, an on-off valve 241 is provided and a pump pipe (not shown) is connected to the wet recovered product discharge pipe 24 (see FIG. 5) connected to the tailgate 4.
