[0035] Among them, the cylinder body 10 is provided with a hollow interior, and the internal space is partitioned to form a mixing chamber 11, a storage chamber 12 and a conveying chamber 13. The mixing chamber 11 and the storage chamber 12 are located at the top of the cylinder body 10, and the conveying chamber 13 communicates with the mixing chamber 11 and the storage chamber 12;

[0036] The asphalt is disposed in the mixing chamber 11, the warm mix additive is disposed in the storage chamber 12, the mixing assembly 20 is disposed in the middle of the mixing chamber 11 and is rotationally connected to the mixing chamber 11. The temperature control assembly 30 includes a plurality of electric heating wires 31, and the electric heating wires 31 are distributed in the bottom space of the mixing chamber 11;

[0037] A first feeding port 10a, a second feeding port 10b and a discharging port 10c are provided on the cylinder body 10. The first feeding port 10a is located at the top of the cylinder body 10 and is communicated with the storage chamber 12. The second feeding port 10b and the discharging port 10c are both provided on the side wall of the mixing chamber 11. The second feeding port 10b is located at one end of the mixing chamber 11 close to the conveying chamber 13, and the discharging port 10c is located at one end of the mixing chamber 11 close to the electric heating wire 31.

[0038] By adopting the vehicle-mounted structural form of the present utility model, the mixing work can be carried out at any time in the mixing chamber 11, which reduces the time required for the mixing work, can meet the requirements of different construction sites, and improves the flexibility and efficiency of construction. At the same time, by setting the temperature control component 30, the device can carry out effective mixing treatment at different ambient temperatures, ensuring the quality of the mixture and improving the reliability of construction.

[0039] On the basis of the above embodiment, the mixing component 20 includes a first driving member 21, a transmission rod 22 and blades 23. The first driving member 21 is embedded at the bottom of the mixing chamber 11, and the output end is connected to the transmission rod 22. The other end of the transmission rod 22 is rotatably connected to the top of the mixing chamber 11. The blades 23 are sleeved on the transmission rod 22. By embedding the first driving member 21 at the bottom of the mixing chamber 11, the connection of the transmission rod 22 can ensure the stability of the mixing component 20 during high-speed rotation, reduce vibration, and thus ensure the normal and stable operation of the mixing device. By controlling the transmission rod 22 to drive the blades 23 through the first driving member 21, the flow path of the warm mix additive and asphalt in the mixing cavity is optimized, dead corners are reduced, and it is ensured that the mixture is fully mixed in the entire mixing chamber 11.

[0040] On the basis of the above embodiment, multiple groups of blades 23 are arranged along the length direction of the transmission rod 22, and the multiple groups of blades 23 are arranged at equal intervals. The equal interval arrangement of the multiple groups of blades 23 can ensure that during the mixing process, the mixture can be fully mixed in each area of the mixing chamber 11, thereby improving the uniformity of the mixture.

[0041] On the basis of the above embodiment, three groups of blades 23 are provided. It can provide balanced mixing force on the premise of ensuring the transmission effect of the transmission rod 22, ensure that the mixture is fully and evenly mixed in the mixing chamber 11, and improve the mixing efficiency.

[0042] On the basis of the above embodiments, each group of blades 23 includes a central sleeve 231 and a plurality of blade bodies 232. The central sleeve 231 is sleeved on the transmission rod 22. One end of the blade body 232 is shrunk and twisted, and is obliquely fixed on the outer side surface of the central sleeve 231, and the other end extends toward the side away from the transmission rod 22. The included angles between adjacent blade bodies 232 are equal; the design of the central sleeve 231 facilitates the connection between the blade body 232 and the transmission rod 22. One end of the blade body 232 is shrunk and twisted to form a certain inclination angle, which helps to disperse and break up the mixture, ensuring the uniform mixing of the warm mix additive and the asphalt. At the same time, it also avoids the adhesion of the mixture on the blade surface, reducing the difficulty of cleaning and maintenance.

[0043] On the basis of the above embodiments, a second driving member 131, a pump body 132, a first material conveying pipe 133 and a second material conveying pipe 134 are arranged in the conveying chamber 13.

The second material conveying pipe 134 passes through the conveying chamber 13 and the mixing chamber 11 and is connected to the discharge port 10c of the pump body 132. The second driving member 131 is connected to the pump body 132; the connection between the second driving member 131 and the pump body 132 realizes automatic control, reduces manual operation, and improves production efficiency and operation convenience; when the pump body 132 is working, in cooperation with the first material conveying pipe 133 and the second material conveying pipe 134, it realizes the continuous transmission of the warm mix additive from the storage chamber 12 to the conveying chamber 13 and then to the mixing chamber 11, improving the transmission efficiency; and the pump body 132 can adjust the flow rate according to needs to ensure the precise supply of the warm mix additive during the mixing process and avoid waste.

[0044] It should be noted that the first driving member 21 and the second driving member 131 can both be set as motors to control the rotation of the transmission rod 22 or the operation of the pump body 132 through the driving action of the motors, or can be set as other components as long as they can achieve the effect of the rotation of the transmission rod 22 or the operation of the pump body 132. No limitation is made here.

[0045] On the basis of the above embodiments, a filter head 135 is connected to the end of the first material conveying pipe 133 extending into the storage chamber 12. The area of the connection end of the filter head 135 and the first material conveying pipe 133 is smaller than the area of the other end of the filter head 135; the design of the filter head 135 can effectively filter out larger particles or impurities that may exist in the warm mix additive in the storage chamber 12, preventing these substances from entering the first material conveying pipe 133 and being pumped into the mixing chamber 11 to avoid blockage, thereby extending the service life of the device and avoiding damage; the gradually expanding structure of the filter head 135 greatly increases the contact area between the filter head 135 and the warm mix additive, enabling the warm mix additive to flow more smoothly into the first material conveying pipe 133 and improving the conveying and filtering efficiency.

[0046] On the basis of the above embodiments, a first liquid level alarm 121 is provided in the storage chamber 12. The first liquid level alarm 121 is arranged on the inner side wall of the storage chamber 12 and is located at one end close to the first feeding port 10a. The first liquid level alarm 121 can monitor the liquid level of the warm mix agent in the storage chamber 12 in real time, ensuring the continuity and stability of the supply of the warm mix agent, and can also avoid overflow caused by excessive addition of the warm mix agent, reducing waste and environmental pollution. And when the liquid level is abnormal, it can timely send an alarm to the operator, thereby improving the safety of operation.

[0047] On the basis of the above embodiments, a second liquid level alarm 111 is provided in the mixing chamber 11. The second liquid level alarm 111 is arranged on the side of the mixing chamber 11 opposite to the second feeding port 10b inside the mixing chamber 11 and is arranged at a height lower than that of the second feeding port 10b. The height of the second liquid level alarm 111 is lower than that of the second feeding port 10b, which can accurately control the addition amount of asphalt, avoid too much or too little, ensure the safety of the operation in the mixing chamber 11, and accurate liquid level control helps to ensure the uniform mixing of asphalt and warm mix agent during the mixing process, and avoid affecting the mixing effect due to too much or too little asphalt.

[0048] On the basis of the above embodiments, the temperature control component 30 further includes a temperature probe 32. The temperature probe 32 is fixedly arranged on the side wall of the top of the mixing chamber 11 and is located between the second liquid level alarm 111 and the top surface of the mixing chamber 11. The temperature probe 32 can monitor the temperature in the mixing chamber 11 in real time, ensure the mixing of asphalt and warm mix agent at a suitable temperature, and can judge whether it is necessary to turn on the electric heating wire 31 to heat the mixing chamber 11 according to the monitoring situation of the temperature probe 32, so as to provide a suitable mixing environment. The temperature probe 32 can send an alarm when the temperature is abnormal, reminding the operator to take timely measures to avoid safety problems caused by too high or too low temperature.

[0049] The working process of the mixing device in the present utility model is as follows: The warm mix agent and asphalt materials are added through the first feeding port 10a and the second feeding port 10b respectively, and the addition amounts of the two materials are controlled by the first liquid level alarm 121 and the second liquid level alarm 111. After the materials are added, the second driving member 131 controls the pump body 132 to pump the warm mix agent into the mixing chamber 11 according to the addition ratio, and the filter head 135 can block the particles in the warm mix agent. After the warm mix agent is transported in proportion, the first driving member 21 is started to control the mixing assembly 20 to work. As the blades 23 rotate, the warm mix agent and asphalt are evenly mixed and effectively dispersed. When the viscosities of the two materials are too high or the environmental temperature is too low, the electric heating wire 31 is turned on for heating, and the temperature probe 32 is used for monitoring. After the mixing is uniform, the mixture is transported to the stone mixing device through the discharge port 10c for the next operation process.
