Abstract
The invention relates to a gravity hydraulic breaker, which includes a hammer body shell, a hydraulic cylinder, a guide rail, a drill rod seat, a drill rod, an impact piston, a shock absorber, a connecting piece and a steel wire rope, a hydraulic cylinder, a guide rail, a shock absorber and a connecting rod. All parts are connected with the shell of the hammer body through screws, and the drill rod base is connected with the shock absorber through screws. The drill rod is mounted on the drill rod base through two drill rod pins. The track slides up and down, and also includes a transmission mechanism composed of a movable pulley block, a top pulley and a tension pulley. Compared with the prior art, the present invention has the advantages of simple structure, convenient operation, strong crushing capacity, high production efficiency, low use and maintenance costs, and low noise pollution, which can greatly improve the production efficiency of related industries and reduce production costs, thereby improving the profitability of enterprises. Economic benefits, the gravity hydraulic breaker has good application and promotion value.
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 related departments and enterprises. [0004] Chinese paten...
