EXHAUST EMISSION CONTROL DEVICE FOR ROLLING COMPACTION MACHINE
PROBLEM TO BE SOLVED: To provide an exhaust emission control device for a rolling compaction machine capable of shortening a pipeline length of hydraulic piping by installing discharge pressure increasing means such as a load applying valve near an auxiliary pump and a hydraulic oil tank without affecting an installation layout of peripheral devices.SOLUTION: An engine 19 is mounted in an engine room 18 of a front vehicle body 4 and a main pump 23 and an auxiliary pump 24 are directly connected on a rear side of the engine to drive. Using a corner part formed as a dead space between right and left front compaction wheels 2 and right and left side walls 4b, 4c of the front vehicle body 4, a fuel tank 33 of the engine 19 is disposed in the left corner part, and a casing 36 is disposed in the right corner part. The casing 36 is vertically separated into two sections by a barrier 36a, and an upper casing is used as a hydraulic oil tank 25, and the lower casing is used as a valve room 37 in which the load applying valve 29 is disposed. The auxiliary pump 24, the hydraulic oil tank 25 and the load applying valve 29 are connected with hoses 26, 28, 30, respectively.SELECTED DRAWING: Figure 4
【課題】周辺の機器の設置レイアウトに影響を及ぼすことなく、補助ポンプや作動油タンクの近接位置に負荷掛けバルブなどの吐出圧上昇手段を設置して油圧配管の管路長を短縮することができる転圧機械の排気浄化装置を提供する。【解決手段】前部車体４のエンジンルーム１８内にエンジン１９を搭載し、その後側にメインポンプ２３と共に補助ポンプ２４を直結して駆動する。左右の前部転圧輪２と前部車体４の左右両側壁４ｂ，４ｃとの間にデッドスペースとして形成された隅部を利用し、左側の隅部にエンジン１９の燃料タンク３３を配設し、右側の隅部にはケーシング３６を配設する。ケーシング３６内を隔壁３６ａにより上下に２分割して、その上側を作動油タンク２５とし、下側をバルブ室３７として内部に負荷掛けバルブ２９を配設し、これらの補助ポンプ２４、作動油タンク２５及び負荷掛けバルブ２９をホース２６，２８，３０により接続する。【選択図】図４
