Disclosed is a reciprocating impact bevel tooth discharging shovel of a reciprocating impact mining machine, which includes a reciprocating impact box and a reciprocating impact bevel tooth discharging shovel (1). The reciprocating impact box includes a reciprocating impact box body (3), a reciprocating impact power element, and a reciprocating impact guide element (2). One end or both ends of the reciprocating impact guide element (2) extend out of the reciprocating impact box body (3). The reciprocating impact bevel tooth discharging shovel (1) includes a main tooth seat (5), main impact teeth (4), a lateral discharging tooth wing plate (6), and lateral discharging bevel teeth (7). The impacted materials are discharged from a gap which is formed by the lateral discharging bevel teeth (7) towering over the lateral discharging tooth wing plate (6), which reduces resistance of the materials to the reciprocating impact bevel tooth discharging shovel (1).
