Roof bolter mechanism

The invention provides an anchor rod drilling mechanism, and the following technical problem is solved: in the existing mine excavation, the method that requires to use an anchor rod to fix a roadway safely includes that firstly, after the roadway is excavated by roadway-excavating equipment, an anchor rod driller is sent to the excavated roadway manually for the operations of holing and solidification, while the method has the disadvantages that the productivity is low and the work intensity of workers is big. The key points of the invention are that the mechanism consists of a base plate, apoint-fixing mechanism and a drilling mechanism; wherein the point-fixing mechanism comprises an anti-turnover plate, a rotary pin axle, a bearing seat, a principal axis, a fork pin and three varieties of oil cylinders of two differential-complement oil cylinders, one turnover oil cylinder and two oscillating oil cylinders; and the drilling mechanism consists of a reverse turning plate, a chute, a roof-propping device and drilling device. The usage of the invention is that the mechanism, along with roadway excavating equipment, completes the operations of holing and solidification in the intervals of excavating the roadway by roadway excavating equipment, thus improving the productivity and reducing the work intensity of the workers.
