The invention relates to the technical field of coal mine tunneling machines, in particular to a full-hydraulic intelligent drilling, installing and anchoring all-in-one machine which has the functions of drilling, installing, anchoring and protecting simultaneously. The full-hydraulic intelligent drilling, installing and anchoring all-in-one machine specifically comprises a body, a drilling arm system, a scraper box device, an anchoring and protecting platform, and a conveying system, wherein the drilling arm system, the scraper box device, the anchoring and protecting platform and the conveying system are all arranged on the body. The full-hydraulic intelligent drilling, installing and anchoring all-in-one machine has the functions of drilling, installing, anchoring and protecting simultaneously, and multiple operations can be completed with one machine; the drilling arm system is used for drilling shot holes for achieving the purpose of filling explosives, and crushed rock blocks after blasting are cleared away and collected by the scraper box device and then are received by a second conveyor after being conveyed to the rear side of the body by the conveying system; the anchoring and protecting platform can carry out anchoring and protecting operation in a roadway; when the anchoring and protecting platform works, the scraper box device abuts against the top of the roadway for temporary support, so that safety of operation of workers is improved; and the machine can achieve the functions of drilling, installing, anchoring and protecting simultaneously, so that the laborintensity of workers is lowered on the premise of improving the work efficiency.
