Detailed description of the invention
Fig. 1 is the structural representation that the present invention mixes material spray formula concrete sprayer, triple channel spray gun 21 is then used in respectively and send the flow pipe of water, for sending the feed pipe of cement sand, for sending the binary channels wire-feeding pipe of fiber filaments, the effect of triple channel spray gun 21 is exactly that water, cement sand, filament are sprayed on the surface of support engineering equably, and water, cement sand, fiber filaments enter into the rear raw material as support engineering surface spraying of triple channel spray gun 21 by three different feeder connections and be coated on support engineering surface.
Submersible pump 20 is arranged in water tank 19, after submersible pump 20 draws water in water tank 19, water is delivered to the water inlet that send of triple channel spray gun 21 by pipeline.Submersible pump 20 powers to ensure normal requirements of one's work by extraneous power supply, by submersible pump 20 water in water tank 19 can be extracted in real time deliver to triple channel spray gun 21 send water inlet after enter in triple channel spray gun 21.
Cement 15 and sand 16 are given spraying machine 18 after by stirring conveyor 17, the feeding entrance of triple channel spray gun 21 sent into cement 15 and sand 16 by spraying machine 18 under the effect of air compressor machine 14, spraying machine 18 is connected with the feeding entrance of triple channel spray gun 21 by pipeline, and cement 15 and sand 16 enter in triple channel spray gun 21 by the feeding entrance of triple channel spray gun 21 in the effect of air pressure.
Silk carrier pipe 10 is brought the fiber filaments of each fibre ingot 13 in a passage of binary channels spray gun 9, air compressor machine 14 is by high-pressure air hose 8 and regulate that ball valve 11 enters another passage of binary channels spray gun 9, the fiber filaments come from each fibre ingot 13 for wire-feeding pipe provides the power of blowing, and binary channels spray gun 9 is connected with triple channel spray gun 21.Regulate ball valve 11 effectively to regulate the air mass flow in high-pressure air hose 8, then can effectively effectively regulate the Air Force of blowing fiber filaments.
After triple channel spray gun 21 has connected submersible pump 20, spraying machine 18 and binary channels spray gun 9, submersible pump 20, spraying machine 18 and binary channels spray gun 9 can acting in conjunction have been realized the present invention and have been mixed material spray formula concrete sprayer injection water, cement and river sand, four kinds of materials of fiber filaments simultaneously.Four kinds of materials of water, cement and river sand, fiber filaments form concrete spray concretes and are ejected on support engineering domatic, the domatic intensity of support engineering has obtained further reinforcement, the phenomenon that can avoid so the domatic upper concrete spray concrete layer of support engineering often to come off, ftracture.
Fig. 2 is the structural representation one that the present invention mixes material spray formula concrete sprayer spray silk part, and Fig. 3 is the structural representation two that the present invention mixes material spray formula concrete sprayer spray silk part, and spray silk part mainly comprises wire-feeding part and blows a part.
In wire-feeding part, motor 1 is connected with active roller 6 by shaft coupling 2, active roller 6 and return idler 7 contact, active roller 6 is arranged on fixed bearing block 3, return idler 7 is arranged in regulating shaft bearing 4, can be by regulating the adjusting handle 5 in regulating shaft bearing 4 to adjust the gap between active roller 6 and return idler 7, each filament of fibre ingot 13 is by entering the silk carrier pipe 10 that blows silk part after the gap between active roller 6 and return idler 7, the diameter of axle of active roller 6 and return idler 7 is consistent.By adjusting the gap between active roller 6 and return idler 7 and then making each filament of fibre ingot 13 bear different frictional force by time between active roller 6 and return idler 7; By adjusting the rotating speed of motor 1 and then control each fibre ingot 13 gait of march of extracting fiber filaments.Fiber filaments gait of march under motor 1 rotating speed control should be consistent with cement sand jet velocity, has best workmanship with the concrete spray concrete that makes slope support engineering.
Blow in a part silk carrier pipe 10 and the fiber filaments of each fibre ingot 13 is brought into a passage of binary channels spray gun 9, air compressor machine 14 is by high-pressure air hose 8 and regulate that ball valve 11 enters another passage of binary channels spray gun 9, the fiber filaments come from each fibre ingot 13 for wire-feeding pipe provides the power of blowing, and binary channels spray gun 9 is connected with triple channel spray gun 21.Regulate ball valve 11 effectively to regulate the air mass flow in high-pressure air hose 8, then can effectively effectively regulate the Air Force of blowing fiber filaments.In fibre ingot 13, the intensity of each fiber filaments is all very large, in the time that concrete sprayer is worked fiber filaments not can by from air compressor machine 14 and come high wind pull apart.
