用于挖掘机械的气流系统
摘要：
一种挖掘机械，包括动臂、刀盘体、阀门和致动器。所述动臂限定有内部腔室，并且包括联接于所述机架的第一末端、第二末端、和与所述内部腔室流体连通的开口。所述刀盘体包括多个刀头，并且该刀盘体被支撑于所述动臂的第二末端。所述阀门联接于所述动臂，并且可以在闭合位置和打开位置之间移动，在闭合位置时所述开口被覆盖，在打开位置时所述开口至少部分地被敞开。所述致动器联接于所述阀门，以选择性地使阀门在闭合位置和打开位置之间移动。
摘要（英）：

A mining machine includes a boom, a cutter head, a valve, and an actuator. The boom defines an internal chamber and includes a first end coupled to a frame, a second end, and an opening in fluid communication with the internal chamber. The cutter head includes a plurality of cutting bits and is supported on the second end of the boom. The valve is coupled to the boom and is movable between a closed position in which the opening is covered and an open position in which the opening is at least partially uncovered. The actuator is coupled to the valve to selectively move the valve between the closed position and the opened position.
