Slapping type chunk breaking device

The invention discloses a slapping type chunk breaking device integrating characteristics of rotary type and hydraulic impact type breaking hammers. An impact cylinder is used for driving a slapping hammer to rotate to break a chunk in a coal flow system of a fully mechanized coal mining face. The slapping hammer and a swing frame are coaxially installed, the impact cylinder is hinged between theswing frame and the slapping hammer to form a slapping mechanism, an adjusting cylinder supports and fixes the slapping mechanism, and the swing frame can be driven to achieve overall pitch attitude adjustment of the slapping mechanism. By means of an impact control system based on a large-flow integrated valve and an energy accumulator set, strong impact and rapid return of the slapping hammer are achieved, and non-halt operation is achieved. When the device encounters ultra-thick chunks, the slapping mechanism can be adjusted to tilt back to increase the impact increase. When the device encounters ultra-thin chunks,
