The invention relates to the technical field of construction machinery, and discloses a pressure-regulating type
perfusion plugging
machine. The pressure-regulating type
perfusion plugging
machine comprises a gearbox, a gear set, a hand-held motor, a
cam rotating disc, a connecting rod, a movable pull rod, a
piston rod, a
piston copper sleeve, a material cylinder, a check-back device, a pressure gauge, a conveying
pipe, a
metal pipe, an avocado head, a bidirectional switch, a material receiving
bottle, a fixing seat, an adjusting device, a limiting device, a supporting leg and a movable leg, wherein the gear set is movably installed inside the gearbox. According to the pressure-regulating type
perfusion plugging
machine, through the arrangement of the adjusting device, the effective movable distance of the
piston rod in the piston
copper sleeve is changed, so that the size of
slurry discharged from the
piston rod during one time of reciprocation is changed, the
slurry discharging pressure is further changed, the adaptability for cracks on different buildings and cracks of different positions and sizes can be effectively improved, and the
adaptation range of the machine is increased; and meanwhile, suitable
slurry pressure can effectively improve the safety of building crack filling, and the harm caused by excessive pressure can be reduced.
