ROLLING COMPACTION MACHINE
To provide a rolling compaction machine capable of discharging water remaining in a spray device in a short time.SOLUTION: A rolling compaction machine comprises: a spray nozzle 16 for spraying water on front wheels and rear wheels of a rolling compaction machine; a water tank 7 for storing water sprayed from the spray nozzle; a spray pipe 20 for connecting the spray nozzle and the water tank such that water can be circulated; a selector valve 22 for selecting between a flow state that allows water to flow between the water tank and the spray pipe and an air open state which opens the spray pipe to the atmosphere; a pressure release part 14 provided in the spray pipe, which opens when a pressure equal to or higher than a prescribed pressure is applied from the spray nozzle side toward the water tank side; and a pressurized air supply part 32 provided on the spray nozzle side from the pressure release part of the spray pipe, which supplies pressurized air having a pressure equal to or higher than the prescribed pressure. The pressurized air supply part supplies pressurized air, having a pressure equal to or higher than the prescribed pressure, to the spray pipe from the pressurized air supply part when the selector valve is in the air open state.SELECTED DRAWING: Figure 4
【課題】噴霧装置内に残留する水を短時間で排出することができる転圧機械を提供する。【解決手段】転圧機械において、転圧機械の前輪及び後輪に水を噴霧する噴霧ノズル１６と、噴霧ノズルから噴霧される水を貯留する水タンク７と、噴霧ノズルと水タンクとを水を流通可能に接続する噴霧配管２０と、水タンクと噴霧配管との間で水を流通可能にする流通状態と噴霧配管を大気開放する大気開放状態とに切り替える切替弁２２と、噴霧配管に設けられ、噴霧ノズル側から水タンク側に向かって所定圧力以上の圧力が加わると開放する加圧開放部１４と、噴霧配管の加圧開放部より噴霧ノズル側に設けられ、前記所定圧力以上の圧力の加圧空気を供給する加圧空気供給部３２とを備え、加圧空気供給部は、切替弁が大気開放状態のとき、加圧空気供給部から前記所定圧力以上の圧力の加圧空気を噴霧配管に供給する。【選択図】図４
