This device for vibrating compacting of biax posture is mechanical technical field. In order to set up biax frame and eccentric block and eccentric semi-ring technique, the output shaft of its motor is connected in order to leave clearance mode cartridge with the interior circle of base bearing, the output shaft and the master gear of motor, the excircle and the steel wheel of base bearing, the interior circle of base bearing and biax frame and with the shell of motor and the automobile body, the excircle of biax frame and upper bearing and with the excircle of bearing down, the interior circle and the upper shaft of upper bearing, the interior circle of lower bearing with lower, upper shaft and last gear and with last eccentric semi-ring and with last eccentric block, lower with gear down and with lower eccentric semi-ring just with the lower equal fixed connection of eccentric block, the master gear just all is connected with the interlock mode is alive with lower gear with last gear, go up eccentric semi-ring and last eccentric block, lower eccentric semi-ring is 0-180 degree angle with the angle that lower eccentric block installation back constitutes. Be used for pressing the way. The design is novel, the design science, and simple structure, the effect is stable, to road surface different application of force orientation vibrating compacting, extension road roller life-span
