Abstract

The invention discloses a hydraulic milling and drilling machine and a working method thereof. The hydraulic milling and drilling machine comprises a movable machine body and further comprises a largearm, a swing arm oil cylinder, a milling and drilling assembly and a posture adjusting oil cylinder, the large arm is rotatably connected to the front end of the machine body, the bottom end of the swing arm oil cylinder is rotatably connected with the machine body, the output end of the swing arm oil cylinder is rotatably connected with the large arm, the milling and drilling assembly is rotatably connected to the front end of the large arm, the bottom end of the posture adjusting oil cylinder is rotatably connected with the large arm, and the output end of the posture adjusting oil cylinderis rotatably connected with the milling and drilling assembly. The milling and drilling machine is good in working stability during milling and drilling, is hydraulically driven, is strong in power and high in milling and drilling efficiency, can be suitable for crushing, milling and drilling large-volume rocks, and is low in construction cost and good in construction environment.

Description

technical field [0001] The invention relates to the technical field of rock milling and drilling, in particular to a hydraulic milling and drilling machine and a working method thereof. Background technique [0002] In various operations such as mining, tunneling, roadway construction, etc., it is often faced with the entire rock. Since it is necessary to carry out hollowing operations inside the mountain, and because there is no free surface relative to the crushing direction, the construction has caused great damage. Difficult, the usual construction methods include explosives, hammering rock drilling, etc. Among them, the use of explosive blasting has many limitations and cannot be used in many construction environments. The hammer rock drilling method has the disadvantages of low efficiency, high noise, and a lot of dust, especially when encountering hard rock. [0003] For this reason, the process of milling and drilling first, and then crushing can be used to realize ...
