[0025] The following is in conjunction with the appendix Figure 1 and 2 The specific embodiments of this utility model will be further described in detail below.

[0026] In specific implementation, this utility model, in conjunction with the appendix Figure 1 and 2A foamed asphalt vibrating mixing truck includes a vehicle body 1, which is capable of constant-speed self-drive or manual driving. The vehicle body 1 is equipped with a milling material conveying system, a vibrating mixing system, a recycled material transfer system, and a control assembly for driving each system. The milling material conveying system transports materials into the vibrating mixing system, and the recycled material transfer system transfers the finished material discharged from the vibrating mixing system. In this embodiment, the milling material conveying system is mainly used to transport milled mixture from the original road surface. The milling material conveying system includes a belt conveyor 3 installed on the vehicle body 1, with a receiving bin 4 installed at the front end of the belt conveyor 3. The milled mixture is fed into the receiving bin 4 and then transported to the vibrating mixing system via the belt conveyor 3. The vibrating mixing system includes a vibrating mixer 2, an emulsified asphalt feeding system, and a feed... The water system and metering system are configured. The feed inlet of the vibratory mixer 2 is connected to the milling material conveying system. The end of the belt conveyor 3 is connected to the feed hopper 5 installed on the vibratory mixer 2. The recycled material transfer system is connected to the discharge outlet of the vibratory mixer 2. In this embodiment, the recycled material transfer system includes a transfer conveyor 6 installed on the vehicle body 1. In this embodiment, the milling mixture will be transported to the vibratory mixer 2 by the belt conveyor 3. At the same time, emulsified asphalt and water, which have been transported by the emulsified asphalt supply system and the water supply system, will also be added to the vibratory mixer 2. The recycled mixture is formed by the continuous stirring action of the vibratory mixer 2. The recycled mixture is transported to the subsequent paving process by the transfer conveyor 6. The metering system is configured to meter the milling mixture, emulsified asphalt and water to add materials to the vibratory mixer 2 according to the set mix ratio.

[0027] In this embodiment, the transfer conveyor 6 is driven by a swing drive mechanism mounted on the vehicle body 1, enabling it to swing while conveying the recycled mixture, facilitating the paving of the recycled mixture. The swing drive mechanism includes a rotating disk 7 rotatably mounted on the vehicle body 1, driven by a hydraulic rod mounted on the vehicle body 1, and a boom 8 supporting the transfer conveyor 6. A winch is mounted on the boom 8. One end of the transfer conveyor 6 is hinged to the rotating disk 7, while the other end is connected to a steel cable on the winch. This allows the transfer conveyor 6 to rotate at a certain angle following the rotating disk 7 under the drive of the hydraulic rod. By controlling the reciprocating extension and retraction of the hydraulic rod, the transfer conveyor 6 can swing. Simultaneously, the winch's movement drives the steel cable to rotate around its hinge axis, adjusting the height of the transfer conveyor 6. The structure is simple and the operation is convenient.

[0028] In this embodiment, the emulsified asphalt supply system includes an asphalt pump 9, which is connected to the vibrating mixer 2 via an asphalt pipeline 10. The water supply system includes a water supply pipeline 11, which is connected to the vibrating mixer 2. During actual construction, the emulsified asphalt will be directly pumped into the asphalt pipeline 10 via the asphalt pump 9. As per the specifications, in this embodiment, the metering system includes a weighing device installed on the belt conveyor 3 for weighing the milled material entering the vibrating mixer 2, and a target-type weighing device installed on the asphalt pipeline 10. The flow meter 12 is used to measure the emulsified asphalt entering the vibratory mixer 2. It also includes an electromagnetic flow valve 13 installed on the water supply pipeline 11 to measure the water entering the vibratory mixer 2. The weighing device, the target flow meter 12 and the electromagnetic flow valve 13 are all controlled by the control assembly. The control assembly automatically adjusts the target flow meter 12 and the electromagnetic flow valve 13 according to the set mix ratio based on the weight of the milled mixture measured by the weighing device, thereby controlling the amount of emulsified asphalt and water entering the vibratory mixer 2.

[0029] In this embodiment, an anti-clogging system installed on the vehicle body is also included. The anti-clogging system includes a heating box 14 installed on the vehicle body. The heating box 14 contains heat transfer oil and a heater. During actual operation, the heater is also controlled by the control assembly, automatically controlling the temperature of the heat transfer oil in the heating box 14. A heat transfer oil pipe is connected to the heating box and is sleeved on the asphalt pipeline connected to the asphalt pump 9. Specifically, the heat transfer oil pipe and the asphalt pipeline 10 are arranged in a double-layer pipe configuration. The heat transfer oil heats the asphalt material in the asphalt pipeline 10 connected to the asphalt pump 9 through the heat transfer oil pipe. Specifically, by heating and insulating the asphalt pipeline 10 at the asphalt pump 9, the system ensures that the asphalt material remains warm for a period of time after construction is completed. Inside, the emulsified asphalt at asphalt pump 9 remains in a fluid state to prevent clumping of the emulsified asphalt at pump 9 due to the lack of subsequent emulsified asphalt flow. This facilitates cleaning after construction and allows for preheating before the next construction, reducing the likelihood of clumping and blockage at pump 9 when the outdoor ambient temperature is too low. Additionally, the heat-conducting oil pipe is wrapped with an insulation layer to prevent burns from accidental contact and to prevent significant heat loss, thus enhancing the heating effect. Furthermore, this embodiment includes a power generation system 15 installed on the vehicle body, which supplies power to all electrical units, ensuring the normal operation of each system.
