Asphalt distributor truck is a type of black road construction machinery, which is the main equipment for the construction of highways, urban roads, airports, and port terminals. When using asphalt penetration method, asphalt layer surface treatment method to construct asphalt pavement or maintain asphalt or residual oil pavement, asphalt distributor trucks can be used to transport and distribute liquid asphalt (including hot asphalt, emulsified asphalt, and residual oil). In addition, it can also supply asphalt binder to locally crushed soil for the construction of asphalt stabilized soil pavement or pavement base. When constructing the permeable layer, waterproof layer, and bonding layer of the asphalt pavement of high-grade highways, high viscosity modified asphalt, heavy traffic asphalt, modified emulsified asphalt, emulsified asphalt, etc. can be sprayed. It can also be used for asphalt covering and spraying in highway maintenance, as well as for county and township level highway oil road construction implementing layered paving technology.

14-16 ton Shacman 6x4 Asphalt Distributor Truck Asphalt Distributor Truck Structure:
It consists of an inner liner, insulation material, outer shell, partition, combustion chamber, asphalt pipeline inside the tank, thermal oil pipeline, gas storage cylinder, oil filling port, capacity meter, decorative panel, etc. The tank body is an elliptical cylinder, with the inner and outer layers welded from steel plates. The two layers are filled with aluminum silicate insulation material, with a thickness of 50-100mm, and covered with stainless steel plates. There is a sink groove at the bottom, which facilitates the absorption of asphalt inside the tank. There are 5 installation feet at the bottom of the tank that are welded together with the auxiliary beam and then fixed on the frame. The outer layer of the combustion chamber is a thermal oil heating chamber, with a row of thermal oil heating pipes installed at the bottom. The volumetric meter is used to indicate the level of asphalt in the tank.
(2) 14-16 ton Shacman 6x4 asphalt distributor power transmission system
Composed of power take-off, pump transmission device, hydraulic system, etc. Generally, the hydraulic pump is driven by the output power of the power take-off installed on the chassis engine or transmission output port, providing necessary power for the asphalt distribution device. The hydraulic system consists of a hydraulic pump, relief valve, directional valve, hydraulic motor, hydraulic pipeline, etc.
(3) 14-16 ton Shacman 6x4 Bridge Asphalt Distributor Truck Asphalt Pump and Pipeline System
Composed of asphalt pump, filter, valve, spraying pipeline, cylinder nozzle assembly, etc. The main functions of controlling the flow direction of liquid asphalt in pipelines through different combinations of valves are as follows: self suction asphalt filling, rear pipe spraying, handheld spray pipe spraying, circulation, suction, cleaning, etc.
(4) The asphalt heating and thermal oil system of the 14-16 ton Shacman 6x4 asphalt distributor consists of a combustion heating system and a thermal oil circulation heating system.
(5) 14-16 ton Shacman 6x4 asphalt distributor asphalt pipeline cleaning system
There are two parts: diesel cleaning and high-pressure air flushing. The diesel cleaning section consists of a diesel tank, an inlet copper ball valve, and pipelines, while the high-pressure air flushing section consists of an air storage cylinder, one-way valve, air valve, etc.
(6) Electrical and control system of 14-16 ton Shacman 6x4 asphalt distributor truck
The electrical control system is divided into two parts: DC circuit and AC circuit. The DC circuit consists of a power take-off, reducer, cooler, hydraulic directional valve, rear nozzle lifting, rear work light control circuit, and automatic control system circuit; The AC circuit consists of a generator, a burner, and a thermal oil motor circuit.
Performance advantages of 14-16 ton Shacman 6x4 asphalt distributor truck:
1. According to the requirements of spraying amount and operation width, the computer can combine the row type nozzles in any form;
2. The distribution control of asphalt can be achieved not only in the driver's cabin, but also on the operating platform at the rear of the vehicle;
3. The heating system adopts an Italian imported burner with automatic ignition and temperature control functions;
4. Adopting internationally advanced imported high viscosity asphalt pumps, external asphalt can be pumped into the tank to achieve "self suction", and the asphalt inside the tank can also be pumped out;
5. The asphalt spraying rod adopts a three-stage folding structure. Double or multiple spraying can be achieved 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;
6. There is sedimentation inside the asphalt tank body
