The working principle of the invention is as follows:

the piling action is carried out, firstly, a force accumulation action is carried out, the motor 3 drives the gear I4 to rotate clockwise through the output shaft (as shown in figure 1), when the gear I4 is meshed with the gear II 5, the gear I4 rotates to drive the gear II 5 to rotate anticlockwise, so that the gear II 5 drives the hammer rod 8 to drive the hammer head 10 to move, the hammer head 10 is pulled to one side close to the motor 3, and when the gear II 5 drives the hammer rod 8 to rotate to exceed the highest point, the hammer rod 8 moves towards one side close to the motor 3 in the chute 6 through the sliding block 7, at the moment, the tension spring 11 is stretched to the utmost, the force accumulation action is completed, along with the continuous rotation of the gear I4, as the gear I4 is an incomplete gear, the gear I4 can be disengaged from the gear II 5, so that the meshing action of the gear I4 is lost, and the gear II 5 can be pulled to rotate clockwise under the action of the tension spring 11, thereby drive the hammer stem 8 towards clockwise rotation, stop rotating when being propped the dogtooth 48 by limiting plate 34, slider 7 can continue downstream in spout 6 along with inertial effect down this moment to drive hammer stem 8 and continue downstream, hammer stem 8 can drive the tup 10 motion, and the tup 10 can be beaten the pile body on the ejection of compact platform 36 downwards, and the lower extreme of tup 10 can stretch out the lower extreme of spacing collar 47, thereby accomplishes the action of piling. Owing to be provided with balancing weight 9, increased the inertia of tup 10, improvement tup 10's that can be great hammering dynamics. The hammering effect is ensured.

The operation of the centering mechanism, while the piling action is carried out, along with the rotation of the gear two 5, the gear two 5 can drive the rocker 28 to move upwards, the rocker 28 can drive the screw rod 31 to move upwards, the screw rod 31 can drive the sliding column 13 to move towards the direction against the pile body through the pull rope 17, so that the pile body can be clamped through the snap ring 16, the pile body can be calibrated to keep vertical downwards, the piling precision is ensured, along with the continuous piling action, the pull rope 17 can drive the sliding column 13 to move towards the middle, the sliding rod 15 can slide into the sliding column 13, the spring two 39 can abut against the sliding rod 15, along with the movement of the sliding column 13, the elastic force action of the spring two 39 can be increased, so that the snap ring 16 can clamp the pile body more tightly, and the spring two 39 can play a role in buffering and damping during the piling, so as to prevent the collision from causing the whole device to vibrate, and further influence the piling effect, and the buffering effect can also make the snap ring 16 last effectual centre gripping in the surface of pile body to guarantee the effect of centre gripping, thereby guarantee the effect of pile. As the movement of the slide column 13 continues, the connecting plate 18 carried by the slide column 13 moves to drive the twisting plates 19 to move, and the two twisting plates 19 rotate the pile body through twisting of the semi-cylindrical columns 44, so that the pile body is easier to drill into the ground when the hammer head 10 performs piling, and the piling efficiency is greatly improved. The snap ring 16 is provided with the rolling ball 29, so that the pile body can rotate and slide up and down while the pile body is fixed by the snap ring 16, the action of downward movement of the pile body is not influenced, the friction force of clamping during piling is reduced, the piling action is convenient to carry out, and the action of the washboard 19 is not influenced.

When pile driving of a pile body is completed, as the frame 1 moves forwards, at the moment, the motor 3 drives the gear I4 to rotate, the second teeth 49 of the gear I4 are firstly meshed with the second teeth 5, the rocker 28 is driven to descend for a certain distance due to the small number of the second teeth 49, the screw 31 loosens the pull rope 17, the sliding column 13 slides outwards under the action of the first spring 14, clamping effect on the pile body is loosened, the pile body can be separated from the snap ring 16 along with the movement of the frame 1, and finally the pile body is separated from the frame 1 through the outlet 26, so that the whole pile driving action is completed.

The work of drilling mechanism, along with the continuation of gear 4 rotates, gear 4's second 49 of dogtooth begin to mesh with gear two 5, thereby drive gear two 5 anticlockwise rotations, gear two 5's rotation can promote rocker 28 downstream, rocker 28 can promote screw rod 31 downstream, because be provided with spacing post 32 on connecting seat 30 and can take place the rotation when screw rod 31 downstream, thereby screw rod 31 can drill the hole downwards, for ground drilling, the hole of drilling is convenient for follow-up pile body and is squeezed into ground more easily, prepare for the pile driving next time, at this moment, gear two 5 drive the motion of hammer stem 8 simultaneously and realize the power storage action.

When the drilling action is carried out, and the pull rope 17 is completely loosened, the sliding column 13 moves towards the direction away from the discharging table 36, the sliding column 13 drives the push rod 42 to move synchronously until the loose pull rope 17 is tensioned, before the sliding column 13 slides to be pulled by the pull rope 17, the push rod 42 on the sliding column 13 starts to contact the discharging frame 22, the push rod 42 pushes the discharging frame 22 to move along with the continuous sliding of the sliding column 13, the clamping rod I38 moves out of the pile box 23, the clamping rod II 40 is clamped into the pile box 23, a plurality of regularly arranged pile bodies are arranged in the pile box 23, when the clamping rod I38 moves out of the pile box 23, the limiting function of the clamping rod I38 is lost, the pile bodies slide downwards from the lower end of the pile box 23 until the lower end of the pile body slides into the discharging hole 45 and fall downwards, and the limiting ring 47 can play a role in correcting the pile bodies, causing it to tend to fall vertically and the falling pile will fall through the outlet 26 into the last drilled hole of the drilling mechanism.

As gear one 4 rotates, gear one 4 begins to disengage from gear two 5 and the above-described action begins to repeat.
