Abstract

An easily removable reciprocating impact head with an anti-rotation slot for a mining machine comprises a reciprocating impact head device (2), wherein the reciprocating impact head device (2) comprises a reciprocating impact head (4), the reciprocating impact head (4) comprising reciprocating impact teeth (5) and a fixed seat (6), and also comprising a snap spring (7) or an elastic pin (8) or a locking pin (9). The reciprocating impact tooth (5) further comprises an impact tooth (16) and an impact tooth shoulder (17). The impact tooth (16) is arranged on an impact tooth insertion post (14) or an impact tooth insert (15), and the impact tooth shoulder (17) is arranged at the lower part of the impact tooth (16) or arranged at the end of the impact tooth insert (15). The reciprocating impact tooth (5) and the fixed seat (6) comprise a groove for arranging the snap spring (7) or the elastic pin (8) or the locking pin (9), and the snap spring (7) or the elastic pin (8) or the locking pin (9) is arranged in the groove so as to connect the fixed seat (6) and the reciprocating impact tooth (5). The snap spring (7) or the elastic pin (8) or the locking pin (9) is subjected to a rearward pulling force of the reciprocating impact motion. The impact tooth insertion post (14) is inserted into a tooth seat insert (11) or a tooth seat insertion post (12) is inserted into the impact tooth insert (15), the impact tooth shoulder (17) closely mates with a tooth seat shoulder (13) to withstand the counterforce of reciprocating impact, and a slot-type anti-rotation structure is snap-fitted with a post-type anti-rotation structure to prevent the reciprocating impact teeth (5) from rotating.
