Detailed description of the invention
As shown in Figure 1, a kind of pneumatic fractured rock facility device, this device comprises air inlet cylinder sleeve 1, high pressure gas storage dividing plate 2, main piston cylinder 3, impact pricker hammer 4, main piston 5, admission valve 6, inlet channel 7, mechanical fastener 8, gases at high pressure air storage chamber 9, guiding control inlet piston 10, spraying high-pressure gas passage 11, gases at high pressure input channel 12, transpiration hole A13, transpiration hole B14.
Described air inlet cylinder sleeve 1 be two, two air inlet cylinder sleeves 1 are symmetricly set on the bottom of this pneumatic fractured rock facility device, and two air inlet cylinder sleeves 1 leave space.
Main piston cylinder 3 is connected respectively by two high pressure gas storage dividing plates 2 with two air inlet cylinder sleeves 1.
Described air inlet cylinder sleeve 1 and high pressure gas storage dividing plate 2 airtight formation high pressure gas storage air chamber 9; Described air inlet cylinder sleeve 1 is respectively arranged with gases at high pressure input channel 12, transpiration hole 13; High pressure gas storage dividing plate 2 is provided with inlet channel 7, and inlet channel 7 is built-in with admission valve 6, and admission valve 6 can cut out inlet channel 7 under gases at high pressure effect; Described gases at high pressure input channel 12 is separately positioned on the outside of air inlet cylinder sleeve 1, and transpiration hole A13 is arranged on the inner side of air inlet cylinder sleeve 1.
Main piston cylinder 3 inside is provided with main piston 5, and main piston 5 can slide along the inner side of main piston cylinder 3; Described main piston 5 one end is connected with guiding and controls inlet piston 10, and the other end is connected with and impacts pricker hammer 4; Described guiding controls inlet piston 10 and matches with two air inlet cylinder sleeves 1, and guiding controls inlet piston 10 and can slide along the outside of two air inlet cylinder sleeves 1; Guiding controls inlet piston 10 both sides and is respectively arranged with transpiration hole B14; Described transpiration hole A13, transpiration hole B14 can aim at when the control inlet piston 10 that leads slides along two air inlet cylinder sleeves 1, to realize the circulation of gases at high pressure; It is discharge chamber that described guiding controls inlet piston 10 inside.
