Mining multifunctional milling and drilling machine

The invention discloses a mining multifunctional milling and drilling machine which comprises a milling mechanism, a frame mechanism, a crawler travelling mechanism and a drilling mechanism, wherein the drilling mechanism comprises a control mechanism, a big arm and a small arm which are sequentially articulated with each other; the control mechanism is fixed on the frame mechanism through a connecting key board and a high-strength bolt; the drilling mechanism can be detached to reduce the weight of the complete machine if necessary; a rapid connecting mechanism is articulated to the front end of the small arm and comprises a first connecting rod and a second connecting rod, wherein one end of the first connecting rod is fixed at the front end of the small arm in an articulation manner, the other end of the connecting rod is articulated with one end of the second connecting rod, and the articulation point is connected to a driving oil cylinder on the small arm; the rapid connecting mechanism also comprises a working head which comprises a working part and a connecting part which are fixedly connected; the connecting part is provided with two screw holes; one screw hole is articulated with the front end of the small arm, and the other screw hole is articulated with the other end of the second connecting rod. According to the mining multifunctional milling and drilling machine, different working heads can be replaced according to different working conditions; the mining multifunctional milling and drilling machine is multifunctional and is high in machine utilization ratio.
