To provide a suction vehicle having such a structure that a sucked matter accommodated in a receiver tank does not easily leak during transportation.SOLUTION: When a negative pressure maintenance switch 15d of a control panel 15 is operated, negative pressure maintenance control is started (S11). When the negative maintenance control is started, first, a suction object is sucked in a receiver tank 5 by drive of a water-sealing type pump 25 (S13). When a full amount sensor 12 turns on (S13: YES) by this suction, a second automatic valve 18 provided at a suction port 8 is closed (S14). Thereafter, a first automatic valve 17 provided at an air discharge port 6 is closed (S15), and PTO turns off. By this, a negative pressure is maintained in the receiver tank 5, and the suction vehicle 2 can travel (S17).SELECTED DRAWING: Figure 5

    【課題】レシーバタンク内に収容された吸引物が運搬中に漏れにくい構造を有する吸引車を提供する。【解決手段】操作パネル15の負圧維持スイッチ15dが操作されると、負圧維持制御が開始する(S11)。負圧維持制御が開始されると、まず、水封式ポンプ25の駆動により、吸引対象物がレシーバタンク5内に吸引される(S13)。この吸引によって、満量センサ12がONすると(S13でYES)、吸引口8に設けられた第2自動弁18が閉じる(S14)。その後、エア排出口6に設けられた第1自動弁17が閉じ(S15)、PTOがOFFする。これによって、レシーバタンク5内は負圧に維持された状態になり、吸引車2の走行が可能になる(S17)。【選択図】図5
