PTJ-120 Sprayer Machine pavement flatness is one of the important indicators to evaluate the quality of pavement. The flatness of the PTJ-120 Sprayer MachineSprayer pavement is directly related to the state of force of the screed in the Sprayer operation. The force of the screed is related to the suspension and geometry of the PTJ-120 Sprayer Machine. Almost all PTJ-120 Sprayer Machines, the ironing device is suspended from the main unit: the front end of the left and right traction arms of the ironing device is hinged to the support in the middle of the left and right sides of the main unit; the rear side panel of the main unit and the ironing behind it The flat device bodies are connected by two hydraulic cylinders. Manipulating the hydraulic cylinder to expand and contract the piston rod allows the ironing device to swing around the front end of the traction arm (drag point) to reduce or raise the ironing device. Depending on the operating conditions of the hydraulic cylinders in the Sprayer operation, the PTJ-120 Sprayer Machine can be operated in two ways, namely the forced Prayer operating principle and the floating Sprayer working principle.
