The invention discloses an anchoring agent filling device and underground coal mine anchoring equipment, and belongs to the technical field of underground coal mine roof maintenance. The anchoring agent filling device comprises a guiding guide pipe, a chemical spraying guide pipe connected into the guiding guide pipe in a sliding mode and a driving oil cylinder driving the chemical spraying guide pipe to slide. The first end of the chemical spraying guide pipe is connected with a chemical spraying device, and the second end of the chemical spraying guide pipe can be driven by the driving oil cylinder to penetrate out of the guiding guide pipe and extending into the drill hole; a rotating baffle is arranged at the end part, close to the second end of the chemical spraying guide pipe, of the guiding guide pipe; and the rotating baffle is switched between the first position in which the guiding guide pipe is closed and the second position in which the guiding guide pipe is opened. The problems that the anchoring agent filling effect of existing anchoring equipment is poor, and a coal slime mixture in the drill hole easily enters an anchoring agent filling device are solved.
Description
technical field [0001] The invention belongs to the technical field of coal mine underground maintenance, and specifically discloses an anchoring agent filling device and coal mine underground anchoring equipment. Background technique [0002] Mine roof maintenance is an important technical procedure in roadway excavation, which has great significance in the field of safe mining and excavation technology. Bolt support is the main support form of coal mine roof maintenance in my country. [0003] At present, roadway support mainly uses manual filling of resin anchoring agent, resulting in low work efficiency and high work intensity. In order to improve production efficiency, more and more industrial and mining enterprises use automatic anchoring equipment for bolt support. Among them, the anchoring agent filling device in the automatic anchoring equipment uses high-pressure gas or other driving mechanisms to inject the anchoring agent into the drilling hole, so that workers ...
