A floating sealing method of a floating bushing sealing reciprocating impact apparatus and a floating sealing reciprocating impact apparatus of a sealing floating bushing of a mining loader, comprising a reciprocating impact box body (3), a reciprocating impact guide mechanism (1), a reciprocating impact actuating mechanism (5), a floating bushing floating sealing mechanism (2), an impact head (6) and the like. The floating bushing floating sealing mechanism comprises a floating bushing positioning seat (12), a sealing floating bushing (13), a spacer bushing outer sealing piece (10), a spacer bushing inner sealing piece (11), a floating bushing locking piece (9) and the like. The floating bushing positioning seat comprises a floating bushing positioning seat outer port (18), a floating bushing positioning seat cavity (17), a floating bushing shoulder (16) and the like. When an outer sealing end of the sealing floating bushing is arranged with a floating bushing outer end plane (19), a floating bushing inner end arc surface (20) is arranged at an inner sealing end of the sealing floating bushing, avoiding that the eccentric wear spacer bushing inner sealing piece cannot be adjusted after a floating sealing bushing tilts, and the sealing floating bushing and the like drop from the floating bushing positioning seat when shock prevention guiding elements (4) including the floating bushing locking piece, floating bushing shoulder and the like move in a reciprocating manner. |
