The invention discloses a cutter head based on the space-time arrangement of high-pressure water jets with
oblique cutting angles. It includes No. 1 high-pressure water
nozzle, mechanical hob, No. 2 high-pressure water
nozzle and mechanical scraper; No. 1 high-pressure water
nozzle and No. The high-pressure water nozzles at the first position are arranged in opposite directions; when the high-pressure water nozzles at the second position spray the rock
mass, the incident angle is 45 degrees, and the incident point is the midpoint of the
hypotenuse of the rock
mass; the high-pressure water nozzles at the first position, the mechanical hob, and the second The high-pressure water nozzle and mechanical scraper
cut grooves according to the
water jet sprayed by the high-pressure water nozzle of the first position, the mechanical hob rolls down the trapezoidal rock
mass, and the high-pressure
water jet sprayed by the high-pressure water nozzle of the second position divides the trapezoidal rock convex block And the rock-breaking mode installation arrangement of mechanical scraper
cutting and removing rock mass. The invention has the advantages of reducing the application ratio of
mechanical energy, improving the crushing efficiency of rocks, effectively reducing the
mechanical wear of cutters, and reducing the
operating temperature of the working face.
