Hard rock crushing system

Abstract

The invention discloses a hard rock crushing system. The hard rock crushing system comprises a triangular crawler walking part, a cutting part, a working arm, a power part and a hydraulic system, wherein a bottom frame is arranged on the upper part of the triangular crawler walking part; a rotating frame is connected with the bottom frame through a rotating bearing; a rotating device, a water tank, an operating room, a working arm base, the power part and the hydraulic system are arranged on the rotating frame; the working arm is hinged to the working arm base; the cutting part is hinged to the bottom frame. According to the hard rock crushing system, the width of a machine body is small; the triangular crawler walking part is adopted, the environmental adaptability is high, the traction force is high, the climbing capacity is high, the obstacle crossing ability is high, the structure of each part is simple and compact, and the hard rock crushing system is convenient to assemble and disassemble; a trench with fixed width, adjustable depth and the rock hardness f less than or equal to 16 can be dug; the trench is regular; the labor intensity of workers is alleviated; the work efficiency is improved.

Description

technical field [0001] The invention relates to a hard rock crushing system, in particular to a hard rock crushing system suitable for excavating trenches in hard roadways of coal mines. Background technique [0002] Coal is the main energy source in my country, and the energy structure will not undergo major changes for a long period of time in the future. At present, the process of domestic coal mining mechanization is accelerating, and most of the drainage ditches in underground coal mines are excavated manually by using hand-held jackhammers. , Bring many difficulties to coal mine safety production. Especially when encountering a hard base plate, the hand-held pneumatic pick cannot be broken, the pick head is seriously damaged, the number of replacements is high, the efficiency is low, the vibration is severe, and it is difficult for the worker to hold it, which seriously affects the health of the worker. However, the existing trenching machinery has a relatively large...

Problems solved by technology

At present, the process of domestic coal mining mechanization is accelerating, and most of the drainage ditches in underground coal mines are excavated manually by using hand-held jackhammers. , has brought many difficulties to coal mine safety production

Especially when encountering a hard floor, the hand-held air pick cannot be broken, the pick head is seriously damaged, the number of replacements is high, the efficiency is low, the vibration is severe, and it is difficult for the worker to hold it, which seriously affects the health of the worker.

However, the existing trenching machinery has a relatively large volume, especially a large fuselage width, and has a small adaptability to the complex, narrow and harsh environment of coal mine roadways. Low
