Abstract

The invention relates to a gravity type quartering hammer which comprises a hammer body shell. A hydraulic cylinder and a pulley rotary mechanism are arranged on the hammer body shell. A guide cylinder is arranged on one side of the hammer body shell. A top end pulley is arranged at the top end of the guide cylinder. A drill rod is arranged at the lower end of the guide cylinder. An impact hammer is arranged in the guide cylinder. The upper end of the impact hammer is connected with the head end of a steel wire rope and after being wound around the top end pulley and the pulley rotary mechanism sequentially, the tail end of the steel wire rope is fixed to the hammer body shell. The hydraulic cylinder and the pulley rotary mechanism are connected. Compared with the prior art, the gravity type quartering hammer is simple in structure, convenient to operate, high in production efficiency, low in use and maintenance cost, small in noise pollution and capable of greatly improving production efficiency of related industries, reducing production cost and improving economic benefits of an enterprise. The gravity type quartering hammer has the good application and popularization value.

Description

technical field [0001] The invention relates to a rock ore crushing machine, in particular to a gravity type 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 patent CN20275260...
