Referring to FIGS. 4-5: the motion cycle of the trigger 19 in the slow single-action mode of the pneumatic hammer is as follows: keeping the two-sided shift lock 18 in the slow single-action position. The constructor holds the trigger 19 of both sides simultaneously with both hands, and trigger 19 rotates around first spring axle 21, and trigger 19 pointed end promotes ratchet 22, forces wedge plate 26 to rotate around third spring axle 25, makes wedge plate 26 break away from the wedge groove of hammer stem 3 afterbody, and hammer stem 3 unblock this moment, rotates to handle 20 department along with trigger 19, and trigger 19 pointed end breaks away from ratchet 22, and ratchet 22 and wedge plate 26 rebound under the elastic action of third spring axle 25 this moment and reset to the spacer pin 24 position. When the trigger 19 is released, the second spring shaft 23 can rotate reversely but can not rotate normally, and the elastic rigidity of the second spring shaft 23 is far less than that of the third spring shaft 25, so that the ratchet hook 22 is folded reversely, the trigger 19 is reset, and then the wedge plate 26 is pushed open when the hammer rod 3 moves to reset, and the wedge plate 26 is embedded into the wedge groove at the tail end of the hammer rod 3 again to lock the hammer rod 3.
Referring to FIGS. 6-7: the trigger 19 in the pneumatic hammer fast interlock mode moves in a cycle of: the two-side switching lock 18 is rotated by 90 degrees to switch to the fast interlocking gear. The constructor holds both sides trigger 19 simultaneously between the fingers with both hands, trigger 19 rotates around first spring shaft 21, trigger 19 most advanced promotion ratchet 22, force wedge plate 26 to rotate around third spring shaft 25, make wedge plate 26 break away from the wedge groove of hammer stem 3 afterbody, hammer stem 3 unblock this moment, and because the lug that switches lock 18 has restricted trigger 19's motion, consequently when trigger 19 held between the fingers to spacing department, trigger 19 most advanced can not break away from ratchet 22, ratchet 22 and wedge plate 26 can't reset by oneself this moment, hammer stem 3 remains the unblock state all the time, under the effect of confession exhaust unit, can realize reciprocal interlock. When the constructor loosens the trigger 19, the ratchet hook 22 and the wedge-shaped plate 26 can be reset, when the hammer rod 3 is reset, the wedge-shaped plate 26 is pushed open, the wedge-shaped plate 26 is embedded into the wedge-shaped groove at the tail end of the hammer rod 3 again, and the hammer rod 3 is locked.
The working process of the embodiment is as follows:
when using pneumatic hammer, according to planting a stake tail 27 diameter, change the reducer pipe 1 of suitable bore, constructor both hands gripping both sides handle 20 to will plant a stake tail 27 and embolia reducer pipe 1, plant a stake tail 27 and can be injectd the depth of insertion by the spacing ring in the reducer pipe 1, reserve sufficient hitting distance for hammer stem 3. The constructor pinches the triggers 19 at both sides simultaneously with both hands to unlock the tailstock 7. The compressed air in the air bottle 10 is connected to the right cavity of the pressure reversing valve 13 through a hole in the valve seat 11 and the second joint 9; the compressed air in the air bottle 10 is connected to the cavity on the left side of the pressure reversing valve 13 through the hole in the valve seat 11, the second joint 9, the energy accumulator 8, the first air pipe 5, the first joint 2, the first air chamber 28 and the third air pipe 14. The diameter of the left cavity of the valve core of the pressure reversing valve 13 is large, the diameter of the right cavity is small, the pressure intensity on the two sides is consistent, the pressure intensity on the left side is larger than that on the right side, therefore, the valve core of the pressure reversing valve 13 moves towards the right side, the compressed air in the air bottle 10 is connected with the third air chamber 30 through the hole path in the valve seat 11, the valve core of the pressure reversing valve 13 and the second air pipe 6, meanwhile, the energy accumulator 8 supplies energy to the third air chamber 30 through the second connector 9, and because the pressure of the third air chamber 30 is larger than that of the first air chamber 28, the hammer rod 3 is driven to downwards strike the pile planting tail 27. When the hammer rod 3 moves to the position contacting with the tail 27 of the pile planting pile, the left cavity of the pressure reversing valve 13 is connected with the one-way air release valve 12 through the third air pipe 14, the second air chamber 29 and the fourth air pipe 15, so that the left cavity of the pressure reversing valve 13 loses pressure, and the valve core moves to the left under the action of air pressure in the right cavity. At this time, the third air chamber 30 is connected with the one-way air release valve 12 through the second air pipe 6, the valve core of the pressure reversing valve 13 and the inner hole path of the valve seat 11, so that the third air chamber 30 loses pressure, and the hammer rod 3 moves upwards under the action of the air pressure in the first air chamber 28 until the hammer rod is reset.
