The power is transmitted from the output of the second-type chassis full-power power take-off through the drive shaft to the hydraulic pump. The hydraulic pump generates hydraulic energy that is transmitted to the hydraulic motor through the oil pipe. The hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the kinetic energy through the reducer. The mixing tank can realize the positive reversal and the rotation speed of the stirring tank by adjusting the angle of the servo handle of the hydraulic pump (double acting variable) to realize the operations of ramming, stirring, stirring and discharging.
