Abstract

The invention belongs to the technical field of breakers, in particular to a drill rod-triggered breaker based on hydraulic valve control, which comprises a drill rod, a drill rod sleeve, an impact hammer, a hydraulic pump, a crank, a crank slider, a side plate connecting plate, a rocker The drill rod is installed inside the drill rod sleeve through the sliding cooperation between the drill rod guide block and the drill rod sleeve sliding hole, and the drill rod spring is installed on the guide block, which plays the role of resetting the drill rod when the drill rod is reciprocating. Action; the impact hammer is driven by the hydraulic pump through the crank-rocker mechanism to periodically strike the drill rod, thereby causing the drill rod to break the object. In the present invention, only when the drill rod exerts a certain force on the object and the drill rod retracts inwards will the beating mechanism be activated, and as long as the drill rod leaves the object, the beating mechanism will immediately stop beating, which prevents the drill rod from appearing empty hammering, and improves the drilling efficiency. the service life of the rod. Has better use effect.

Description

Technical field

[0001] The invention belongs to the technical field of breaking hammers, in particular to a drill rod triggered breaking hammer based on hydraulic valve control. 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 drill rod trigger breaker based on hydraulic valve control to solve t...
