ПВК型机械振动式掘进康拜因(见图)系自行式设备,它用振动工作机构及安设于此振动机构上的水枪的水流来保证机械化破坏煤质工作面。用过的水流清洗和运输自工作面落下的煤。设有冲击振动机构的落煤工作机构用于工作面的掏槽及破坏煤层。冲击振动机构的冲击次数每分钟为1000—2000次,振幅为10—15毫米,它是沿节理裂隙破坏煤,而水枪的水流能促使煤从煤体上强力地分离 ПВК Mechanical Vibratory Excavation Kang Baiin (see photo) is a self-propelled equipment that uses mechanized vandalizing coal face with the flow of vibrating working mechanism and water gun installed on this vibrating mechanism. The used water stream cleans and transports the coal falling from the face. Vibration and vibration mechanism with the coal working institutions for the face of the cut and destruction of coal. The impact of the number of impact vibration mechanism 1000-2000 times per minute, the amplitude of 10-15 mm, it is along the joint fracture destruction of coal, and the water flow of the gun can promote the strong separation of coal from the coal
