The structure of the PTJ-120 Sprayer Machine is generally divided into two parts, that is, the front is the main machine, that is, the tractor; the back is the ironing device, which is the working device. The main unit pulls the screed through the boom. The procedure for the PTJ-120 Sprayer Machine paving operation is this:
(1) Before paving, set the relevant parameters such as paving width, paving thickness, paving speed and vibrating vibration according to the construction requirements.
(2) After the paving starts, the paver pushes the skip, and the mixture on the skip is received into the hopper while driving on the base road.
(3) The mixture received in the hopper is transported to the rear of the main unit via the scraper feeder.
(4) The mixture conveyed to the rear of the main unit is conveyed to the front side of the entire screed device via the screw feeder.
(5) The ironing device travels forward under the traction of the main machine, and the mixture is ironed and tamped to form a flat and dense paving layer for further compaction of the roller.
(6) Perform automatic or manual control during the paving operation to ensure that the paving layer meets the required width, thickness, cross slope and compaction of the construction requirements.
