Emission standard: EURO3/EURO5 Condition:Brand new Origin:Suizhou,Hubei,China Inquire Now Next Product Share Attribute Chassis Brand: Dongfeng Drive Type: 4x2 Color: Customizable White Introduction The Dongfeng 4x2 asphalt crushed seal coating truck is a specialized equipment used for surface treatment of highways, waterproofing of bridge decks, and gravel sealing in lower layers.

It combines the spraying of asphalt binder and the spreading of aggregates synchronously, ensuring the maximum surface . This vehicle has been independently developed and designed by our company , with proprietary in e operation process and making it easy to use.

The overall technical level of the equipment has reached the world's advanced level. Composition and structural characteristics Dongfeng 4x2 asphalt crushed seal coating truck is mainly composed of asphalt sprinkling system, stone spreading system and electrical operating system.

1、Asphalt Sprinkling System Spraying system mainly consists of asphalt tank, heating part, hydraulic part, control part and spraying part.

(1) Asphalt tank The outer wall of the tank is made of stainless steel sandblasted plate, with heat preservation packing in the middle, and the interior is composed of heating boiler and thermal oil coil, which is neat and generous in appearance.

Tank body outside the addition of gas-controlled valve group, the asphalt in the pipeline to achieve the size of the cycle, to avoid the asphalt local overheating, aging.

(2) Heating part Heating device selection of imported burners and supporting high-efficiency boiler, which has a high combustion efficiency, atomization effect, low oil consumption, fast heating speed, safe and stable operation.

No manual supervision is required to ensure that the asphalt in the pipeline can obtain effective heating temperature. (3) Hydraulic part Adopt international famous brand components (hydraulic pump, hydraulic motor) to ensure reliable transmission performance.

(4) Control part The encoder is used to detect the synchronous gravel chip spreader speed and asphalt pump speed accura mported components.

After setting the sprinkling volume, PLC automatically calculates the vehicle speed and pump speed, realizes the automatic control of sprinkling, and can recommend the reasonable vehicle speed for the driver.

(5) Sprinkling part The opening and closing of each nozzle is realized by the separate control of air valve, and the special pipeline design ensures the even pressure and good spraying effect. 2、Stone spreading system The stone spreading system consists of silo, gate control mechanism and spreader.

(1) Silo The silo is installed with an internal shadow hiding type center top turning axle which adopts a through shaft to ensure the smoothness of silo lifting;(2) Door control mechanism The material door is 16-channel control, using the angle spiral angle control instrument, to make the material door to achieve a certain degree of openness, you can set the angle of the material door on the angle control instrument to open the angle of the material door, it is very convenient, accurate, and effective adjustment of the uniformity of dispersal, changing the traditional stone dispersal uneven situation;(3) Spreader part The spreader consists of distributing plate and lowering plate.

The adjusting range of distributing plate and lowering plate is large, which is suitable for different specifications (S3~S20mm) of stone materials. 3、Electrical operation system (1) According to different working requirements to provide the operator with accurate sprinkling parameters.

Through the setting of the parameters on the display screen of the rear operation console, the actual measurement parameters are constantly changing to accura which improves the working efficiency. (3) The width of spraying asphalt and spreading stone can be adjusted according to the width of the road surface.

(4) Adopt limit switch device to control the lifting and lowering of nozzle rack and material bin to avoid over-traveling and injuring people and machines. (5) Configuration of thermal oil automatic alarm device, with material level upper limit, lower limit alarm, asphalt lower limit alarm indication function.

Advantages (1) Exclusive use of full hydraulic drive mode, do not need to add any auxiliary power to make the operation more simple and convenient.

(2) Exclusive use of highly efficient heat-conducting oil boiler heating, so that the speed of temperature rise has been greatly improved, breaking the traditional flue heating method.

(3) The equipment adopts the internal lifting hopper to realize the stone chip spreading construction, which is more convenient for culvert construction, under-bridge construction, and curved road construction;(4) The equipment adopts electric control, with high degree of automation, which can precisely calculate the amount of asphalt spraying and stone chips spreading during the construction process;(5) The material gate control adopts angle meter, which ensures the precision of material discharging of the equipment;(6) Reduces the labor intensity of construction, saves human resources, reduces construction costs, improves work efficiency and work quality;(7) The whole machine runs stably, spreads evenly, and can freely adjust the width of sprinkling asphalt spreading;(8) Good insulation layer to ensure thermal insulation performance index ≤ 20 ℃ / 8h, and anti-corrosion and durable;(9) Can spray all kinds of asphalt media, spreading from S3 ~ S24mm stone;(10) The equipment adopts nozzles with high processing accuracy, so that each nozzle spraying consistency and spraying effect is fully guaranteed;(11) The overall operation is more humanized with remote control and also on-site operation, which brings great convenience to the operator;(12) Through the perfect combination of electrical control and constant pressure device of hydraulic system, it realizes zero-start spraying;(13) The whole asphalt crushed seal coating truck has been improved through many engineering construction, with reliable working performance, convenient operation and maintenance, and high cost performance.

Notes and precautions: 1.Asphalt sprinkler must clean the asphalt pump and pipeline after one operation or when switching the construction site, otherwise it can't work next time. 2.The Dongfeng 4x2 asphalt crushed seal coating truck must check whether the position of each valve is correct before spraying. 3.

Add hot asphalt in the asphal
