Promotion Professional Factory HOWO 8*4 12Wheels 8CBM Asphalt Tank 12 CBM Gravel Tank Chip Spreader Truck

Equipment composition and structural features The synchronous gravel truck is mainly composed of asphalt spreading system, stone material spreading system, electrical operating system and auxiliary system. Asphalt Spraying 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 frosted plate, with insulation filler in the middle, and the inside is composed of a heating boiler and a heat transfer oil coil, with a clean and elegant appearance. The air control valve group added outside the tank realizes the large and small circulation of asphalt in the pipeline and avoids local overheating and aging of the asphalt. 2. Heating part The heating device adopts imported burner and matching high-efficiency boiler, which has high combustion efficiency, good atomization effect, low fuel consumption, fast heating speed, safe and stable operation, etc. There is no need for manual monitoring to ensure that the asphalt in the pipeline can obtain an effective heating temperature. 3. The hydraulic part adopts components (hydraulic pump and hydraulic motor) of internationally renowned brands to ensure reliable transmission performance. 4. The control part uses an encoder to accurately detect the speed of the vehicle and the speed of the asphalt pump to ensure the accuracy of spreading. Among them, the radar, encoder and main circuit switching components are all imported components. After setting the spraying amount, the PLC automatically calculates the vehicle speed and pump speed, realizes the automatic control of spraying, and can recommend a reasonable vehicle speed for the driver. 5. Spraying part The opening and closing of each nozzle is controlled by an individual air valve. Through special pipeline design, uniform pressure and good spraying effect are guaranteed. stone spreading system The stone spreading system consists of a silo, a material door control mechanism and a spreader. Inside the silo, there is an inner shadow hidden-type center-top flip shaft and a through shaft to ensure the stability of the silo’s rise; the material door is controlled by 16 channels, and an angle helix angle controller is used to make the material door reach a certain opening degree. The opening angle of the material door can be set on the angle controller, which is very convenient and accurate. Effectively adjust the uniformity of spreading, changing the traditional situation of uneven stone spreading; the adjustment range of the distribution plate and the blanking plate is large, and it is suitable for stones of different specifications (S3-S24mm). Electrical Operating System 1. Provide operators with accurate spreading parameters according to different work requirements. Through the setting of the display screen parameters on the rear console, the continuous changes of the actual measurement parameters can accurately reflect the operation of the equipment. 2. Manual operation is simple, and manual/automatic switching can be realized, which improves work efficiency. 3. The width of asphalt spraying and stone spreading can be adjusted at will according to the width of the road surface. 4. The limit switch device is used to control the lifting of the nozzle frame and the material bin to avoid damage to the human machine due to overtravel. 5. Equipped with an automatic alarm device for heat transfer oil, it has the functions of upper limit and lower limit alarm of material level, and alarm indication function of lower limit of asphalt
