Asphalt spreader is an intelligent automatic high-tech product for professionally spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt. It is used for the spraying of permeable oil, waterproof layer and adhesive layer for the construction of high-grade highway asphalt pavement bottom layer. The spreader is composed of an automobile chassis, an asphalt tank, an asphalt pumping and spraying system, a heat transfer oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform. The car is easy to operate. On the basis of absorbing various technologies of similar products at home and abroad, it has increased the quality and technical content of construction and highlighted the humanized design of improving construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt distribution, the computer control is stable and reliable, and the technical performance of the vehicle has reached the world advanced level.
Equipment performance characteristics
The car adopts a well-known chassis, excellent and powerful carrying capacity, flexible and light maneuverability, and beautiful appearance, providing safe, efficient and reliable services for the vast number of intercity logistics customers;
According to the needs of spraying volume and working width, the computer can make any combination of determinant nozzles;
The manual/automatic control mode can realize the individual control of each nozzle, thus realizing the arbitrary adjustment of the spraying width.
Asphalt distribution control can not only be done in the cab, but also can be controlled on the operating platform at the rear of the vehicle;
The automatic control system of the car can measure the speed of the vehicle 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 pumping number of the asphalt pump through the system.
The heating system adopts the burner imported from Italy, with automatic ignition and temperature control functions;
Using the international advanced imported high-viscosity asphalt pump, the external asphalt can be pumped into the tank to achieve "self-priming", and the asphalt in the tank can also be pumped out; the key parts of the whole machine (such as hydraulic pump CBQ550-L, hydraulic Motor 05-110-BD31, asphalt pump QGB680, proportional valve EFBG-03-160-HF, automatic
The dynamic control system (CLW-34-01, etc.) adopts internationally renowned components to ensure the reliability of the whole machine and improve the service life;
Under the premise of ensuring that the maintenance and disassembly of other parts are not hindered, each part of the ladder and handrail are arranged for easy operation;
All heat pipes have thermal insulation layers on the outside to reduce heat dissipation and avoid scalding operators;
The vehicle-mounted rapid heating system (10-15℃/h) can improve the heating efficiency and reduce the construction auxiliary time to ensure the spraying temperature;
The asphalt spraying rod adopts a three-section folding structure. Double or multiple spraying can be realized by moving the spraying rod up and down. The spraying range can be expanded by moving the spraying rod left and right, and obstacles can be effectively avoided;
The manual spraying function allows the asphalt to be sprayed through the hand nozzle, which is flexible and convenient, and is suitable for small-scale and corner construction conditions. Get the gun in hand. Open the main oil outlet valve, open the transfer valve, open the oil return valve, and use the oil return valve to adjust the pressure of the spray gun.
There is a sedimentation sewage tank inside the asphalt tank, and is equipped with a liquid level display and alarm and safety devices;
Nozzle flushing This function can blow out the remaining asphalt from the nozzle through diesel fuel and high-pressure air to prevent the asphalt from freezing on the nozzle, which can greatly improve the service life of the nozzle. Close the main oil outlet valve, oil return valve, open the pneumatic valve, open the self-priming valve and open the nozzle in turn.
A good thermal insulation layer can ensure that the static thermal insulation performance index is less than or equal to 12°C/8 hours, and it is anti-corrosion and durable;
The outer packaging of the car is made of stainless steel plate, which is anti-corrosion durable and beautiful.
