A mechanical chisel trigger breaker

Abstract

The invention belongs to the technical field of breaking hammers and particularly relates to a mechanical drill rod triggering breaking hammer. The mechanical drill rod triggering breaking hammer comprises a drill rod, a drill rod sleeve, a hitting hammer, a hydraulic pump, a crank, a crank sliding block, a side board connecting board and a rocker. The drill rod is installed in the drill rod sleeve through the sliding fit of a drill rod guide block and a sliding hole of the drill rod sleeve. Drill rod springs are installed on the guide block. When the drill rod conducts reciprocating hitting work, a drill rod reset effect is achieved. The hitting hammer is driven by the hydraulic pump through a crank and rocker mechanism to periodically hit the drill rod, so that an object is broken by the drill rod. By the adoption of the mechanical drill rod triggering breaking hammer, only after the drill rod applies certain force to the object can the drill rod retract inwards, a hitting mechanism can be started, only the drill rod is separated from the object can the hitting mechanism stop hitting immediately, the phenomenon that the drill rod idles is prevented, and the service life of the drill rod is prolonged. The mechanical drill rod triggering breaking hammer has the good use effect.

Description

Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a mechanical drill rod triggered breaking hammer. Background technique [0002] At present, the breaker has various drive modes such as hydraulic drive, nitrogen drive, nitrogen and hydraulic drive, gravity drive, etc. Each drive mode is achieved by hitting the drill rod at high speed so that the drill rod has a large kinetic energy in an instant to achieve crushing. The effect of the object; when the chisel is hit, the huge kinetic energy is released by breaking the object, but the chisel is often separated from the object during work, and the beating is still in progress at this time, and the huge beating kinetic energy cannot be released. Hitting will cause great damage to the drill rod, resulting in increased equipment operating costs. [0003] The present invention designs a mechanical drill rod trigger breaker to solve the above problems. Contents of the inventi...
