    Modification instructions of Dongfeng 4 tons asphalt distributor

    Manual/automatic control of spraying volume and working width, each nozzle can be controlled separately, and row-type nozzles can be combined freely, so as to realize arbitrary adjustment of spraying width. Spreading control can be carried out in the cab or rear platform. The automatic control system can measure the vehicle speed and automatically calculate the rotation speed of the asphalt pump according to the input spraying amount, spraying width and asphalt type, and then automatically adjust the number of asphalt pumps through the system. The vehicle-mounted rapid heating system (10-15℃/h) can improve the heating efficiency and reduce the auxiliary time of construction to ensure the spraying temperature; the nozzle flushing system can blow the remaining bitumen from the nozzle through diesel oil and high-pressure air to prevent the bitumen from freezing in the nozzle. Improve nozzle life.
