RAMMER
PROBLEM TO BE SOLVED: To provide a rammer that is less likely to affect an engine adversely in terms of heat and induce output decline.SOLUTION: A rammer body 2 has a built-in power conversion mechanism that converts torque of an engine 1 into vertically reciprocating vibration, and a rolling compaction plate disposed at a bottom edge part of the rammer body, the rolling compaction plate being vibrated reciprocally in a vertical direction by the power conversion mechanism. A bracket 9 is disposed at a top part of the rammer body 2, the bracket having a top plate part disposed leaving an interval from the rammer body 2, and an air cleaner 8 is fitted on a top of the top plate part of the bracket 9. The air cleaner 8 has an air inlet part below a built-in filter, and an air outlet 20c above the filter for connecting a bellows-type pipe 22 for introducing air into the engine 1.SELECTED DRAWING: Figure 4
【課題】エンジンに熱的な悪影響を与え、出力低下を招くおそれを低減したランマを提供する。【解決手段】ランマ本体２は、エンジン１の回転力を上下往復振動に変換する動力変換機構を内蔵し、かつ下端部に動力変換機構により上下往復振動される転圧板を有する。ランマ本体２の上部に、ランマ本体２に対して間隔を持たせて配置される天板部を有するブラケット９を設け、ブラケット９の天板部の上部にエアクリーナ８を取付ける。エアクリーナ８は、内蔵するフィルタより下部に空気導入部を有し、フィルタより上部にエンジンへの１への空気導入用の蛇腹式配管２２を接続する空気排出口２０ｃを設ける。【選択図】図４
