Abstract

The invention relates to a gravity type hydraulic breaking hammer which comprises a hammer outer shell, a hydraulic cylinder, a guide rail, a drill rod base, a drill rod, an impacting piston, a vibration reduction device, a connecting piece and a steel wire rope. The hydraulic cylinder, the guide rail, the vibration reduction device and the connecting piece are all connected with the hammer outer shell through screws. The drill rod base is connected with the vibration reduction device through screws. The drill rod is clamped on the drill rod base through two drill rod pins. The impacting piston is located in a rail of the hammer outer shell and vertically slides along the rail during working. The gravity type hydraulic breaking hammer further comprises a transmission mechanism formed by a movable pulley set, a top end pulley and a tensioning pulley. Compared with the prior art, the gravity type hydraulic breaking hammer is simple in structure, convenient to operate, high in breaking capacity, high in production efficiency, low in use and maintenance cost and low in noise pollution, the production efficiency of related industries can be greatly improved, the production cost can be reduced, the economic benefits of enterprises can be accordingly increased, and the gravity type hydraulic breaking hammer has the good application and popularization values.

Description

technical field [0001] The invention relates to the field of rock and mine crushing, in particular to a gravity hydraulic breaking hammer. Background technique [0002] With the development of society, the country's demand for mineral resources and building materials is increasing, and there are higher requirements for the production efficiency of relevant departments and enterprises. Breaking hammer has become the most important rock secondary crushing tool in mining, quarry, construction and other industries. [0003] At present, traditional hydraulic breakers are mainly used. For example, Chinese patent CN101793041A discloses a hydraulic resonance breaker. These traditional hydraulic breakers have complex design structures, high use and maintenance costs, and large noise pollution. For large ores and hard materials The crushing efficiency is low, and these shortcomings have seriously hindered the development of relevant departments and enterprises. [0004] Chinese pate...
