In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a reverse circulation is strikeed and is bored multi-axle actuating mechanism, wherein, includes motor, well axle, rear axle and a hoist section of thick bamboo, install the driving pulley on the output shaft of motor, the driving pulley is connected with driven pulley through belt transmission, between driven pulley, the well axle and all be connected with universal coupling between well axle, the rear axle, the equal fixed mounting in both ends of well axle, rear axle has the driving gear, the driving gear all meshes the transmission and is connected with driven gear, driven gear with the coaxial fixed connection of a hoist section of thick bamboo. The middle axle is provided with a differential mechanism between the left wheel and the right wheel, the middle part is also provided with a differential mechanism between the middle axle and the rear axle, the rear axle is only provided with a differential mechanism between the left wheel and the right wheel, the above mentioned differential mechanisms are all differential mechanisms commonly used in automobiles in the prior art, and the details are not repeated.
Preferably, a clutch is arranged on the driven pulley.
Preferably, the driving gear is fixedly installed at both ends of the middle axle and the rear axle through bolts.
Preferably, the driving gear and the driven gear are both straight gears or helical gears.
Preferably, the middle axle, the rear axle and the winding drum are all mounted on a frame of the impact drill through bearings.
Has the advantages that: compared with the prior art, the utility model has the beneficial effects that: through the setting of well axle, rear axle, realized strikeing and bored the drive of many axles, promoted tup hoist mechanism's bearing capacity by a wide margin, the tup weight can be done bigger, improves pore-forming efficiency, and the pore-forming hangs down the poor great improvement that also has of straightness.
