Abstract

The invention relates to a quartering hammer. The quartering hammer comprises an impact main valve body, an impact rear base fixedly connected to the left end of the impact main valve body and an impact front base fixedly connected to the right end of the impact main valve body. The interior of the impact main valve body is provided with an impact shaft in a matched mode, and a buffering nitrogen bottle is fixedly connected to the upper end of the impact shaft. The impact front base is internally connected with a lining in a matched mode, and the free end of the impact front base is connected with a guiding sleeve in a matched mode. Compared with the prior art, the quartering hammer is simpler in structure, more convenient and rapider to use, and capable of effectively avoiding the hit missing phenomenon in the using process.

Description

technical field [0001] The invention belongs to the technical field of crushing machinery, in particular to a crushing hammer. Background technique [0002] The breaker, referred to as "breaker" or "breaker", is installed on the bucket or bucket of the excavator and loader to break stones, rocks, etc. The working principle of the breaker is: powered by the output pressure oil of the hydraulic pump of the excavator and loader, the reciprocating motion of the piston is controlled through the distribution valve. During the stroke, the rear cavity of the middle cylinder of the hammer is filled with high-pressure hydraulic oil, and the piston is impacted by the compressed nitrogen in the upper cylinder and the high-pressure oil to smash the rock; The piston moves backward and compresses the nitrogen in the upper cylinder, thus completing a working cycle. The repeated stroke and return stroke of the piston makes the drill rod impact and break rocks, stones, concrete, etc., which...
