Pressure-air via after intake interface 617-1, transverse air channel 617-2 and axial stomata 617-3 through annular cloth air drain
617-4 enters in cylinder cap cavity 617-5, sees attached drawing 3,4.
When initial, for piston 611 since gravity is below, the inner chamber of cylinder block of the cylinder body 612 of 611 top of piston passes through two
Cylinder body rod radial air vent 624 communicates with the outside world, and valve block 615 is toppled over to side under the pressure of pressure-air (such as right above
Incline), see that attached drawing 3, valve block 615 cover the air inlet duct 613-4 and air intake duct 613-5 on 613 right side of valve body.Cylinder cap cavity 617-5
Interior compressed air via the first arc air inlet notch 615-3 in the left side of valve block 615,615 lower surface of side valve piece (inclined-plane) with
Gap between 613 upper surface of valve body, then it is radial through the radial air inlet blind hole 613-2 on valve body 613, the first valve body on valve body
Enter cylinder after hole 613-1, the first cylinder body radial hole 621 on 612 top of cylinder body, axial blind hole 622, the second cylinder body radial hole 623
Body cavity of resorption, at this point, the hammer body 611-1 of 611 lower end of piston closes the guide through hole 612-1 of cylinder body lower end, hammer body 611-1's
At closed state, compressed air pushes 611 fast uplink of piston in space between lateral surface and the inner cavity of cylinder body lower end.
After two cylinder body rod radial air vents 624 at the middle part of cylinder body 612 after communicating below piston 611, attached drawing 4, cylinder are seen
Cavity pressure is die-offed under body.The pressure of the side radial air inlet blind hole 613-2 declines, and valve block 615 is above under the pressure of compressed air
Side oscillation to the left, valve block 615 closes the radial air inlet blind hole 613-2 in 613 left side of valve body, and the air inlet duct on 613 right side of valve body
613-4 is opened.Compressed air in cylinder cap cavity 617-5 via the second arc air inlet notch 615-2 on the right side of valve block 615 and is somebody's turn to do
Gap between 613 upper surface of lower surface and valve body of side valve piece 615, then through air inlet duct 613-4, the air intake duct on valve body 613
Inner chamber of cylinder block is directly entered after 613-5, since the air flue of the side is greater than the air flue in left side, and path is short, can push piston 611
Fast downlink.
When hammer body 611-1 in the lower end of piston 611 impacts iron pan, 611 top of piston is also just through cylinder body radial direction
Gas vent 624 is communicated with atmosphere, the pressure drop on 611 top of piston, valve block 615 above under the pressure of pressure-air to the right
It swings, valve block 615 is one side closed by air intake duct 613-5.Movement when repeating initial, repeatedly, the realization of piston 611 connect up and down
Continuous ballistic motion, drives hammer body 611-1 continuously to beat iron pan.
Be not specifically noted in all the utility model specifications be the prior art or can by existing technology
It realizes, it should be appreciated that for those of ordinary skills, it can be modified or changed according to the above description, and
All these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
