Abstract

The invention discloses a non-blasting small and medium-sized tunnel drift or inclined drift tunneling rotary cutter, and relates to the technical field of mine equipment. The non-blasting small and medium-sized tunnel drift or inclined drift tunneling rotary cutter comprises a walking mechanism, a propelling mechanism, a rotary cutting mechanism and a magma conveying mechanism, wherein the rotary cutting mechanism is arranged at the front end of the walking mechanism in a sliding mode, the rotary cutting mechanism is connected with the propelling mechanism for pushing the rotary cutting mechanism to move forwards, and the magma conveying mechanism is arranged between the walking mechanism and the rotary cutting mechanism. According to the non-blasting small and medium-sized tunnel drift or inclined drift tunneling rotary cutter, the rotary cutting mechanism is combined with a magma conveying pump, the rotary cutting mechanism cuts rock, and magma in the rock cutting process is conveyed out through the magma conveying mechanism, so that a traditional rock drilling and blasting operation mode is replaced; and a certain pressure is applied to the rotary cutting mechanism by utilizing the propelling mechanism, so that the rotary cutting mechanism fully cuts the rock, toxic and harmful gases such as smoke and carbon dioxide are avoided, the construction is safer, the workload is small, the hydrogeological structure cannot be damaged, the tunneling time is shortened, and the construction cost is lower.

Description

technical field [0001] The invention relates to the technical field of mine equipment, in particular to a non-blasting rotary cutting machine for small and medium-sized tunnels in horizontal or inclined roadways. Background technique [0002] At this stage, mine level roadway excavation works mainly rely on manual rock drilling, drilling, blasting (blasting), ventilation, risk removal (treatment of pumice), and then manual removal of ballast or use of ballast removal machine, lifting machine, electric scraper or Diesel scrapers, or forklifts and other shoveling (loading) ballast equipment are loaded and unloaded, and then transport equipment such as mine cars, tricycles, and four-wheel vehicles are used to go out of the hole to the outside. The prior art has the following problems: [0003] The first point is that during the excavation of mine level roadways and inclined shafts (upward inclined shafts and downward inclined shafts), there is a lot of noise in rock drilling wi...
