In the exemplary embodiment of the present invention, the opening or closing of the temperature detector 5 may be controlled by the controller 3, but the present invention is not limited thereto, and the temperature detector 5 may also be automatically opened along with the opening of the controller 3. When the stirring rod 9 and the stirring paddle 10 of the stirring device perform stirring motion on the asphalt mixture in the compartment 12, the stirring motion also stirs the heat of the heat-conducting medium in the heat supply pipe 6 inside the compartment 12 from the lower part to the upper part of the compartment 12, so that the temperature distribution of the asphalt mixture in the compartment 12 is relatively uniform.

In an exemplary embodiment of the present invention, the actuating cylinder 7 may be a hydraulic actuating cylinder, but the present invention is not limited thereto.

After long-distance transportation, when the asphalt mixture in the compartment 12 arrives at a construction site or needs to be unloaded, the driving motor 13 can be turned off, the actuating cylinder 7 can be started, one end of the compartment 12 can be lifted under the action of the actuating cylinder 7, so that a certain angle is formed between the compartment 12 and the ground, as shown in fig. 1, when the angle between the compartment 12 and the ground meets a certain condition, the discharge port 8 can be opened, so that the asphalt mixture in the compartment 12 can flow out through the discharge port 8, and the unloading of the asphalt mixture can be realized.

After the asphalt mixture is unloaded, the discharge opening 8 can be closed, and then the actuating rod can be folded back or retracted into the vehicle body, so that one end of the compartment body 12 returns to the original position, and the compartment body 12 is driven to return to the original horizontal position. Since the asphalt mixture in the compartment 12 has been completely loaded, it is not necessary to supply heat to it, and the heater 4, the circulation pump 2 and the temperature detector 5 can be turned off. In an exemplary embodiment of the present invention, the heater 4, the circulation pump 2, and the temperature detector 5 may be turned off by the controller 3, and then the controller 3 is turned off, but the present invention is not limited thereto. For example, the heater 4, the circulation pump 2, and the temperature detector 5 may be automatically turned off when the controller 3 is turned off. The vehicle may then travel to a mixing station in preparation for the next asphalt mix transport.

As described above, according to the utility model discloses a vehicle that is used for carriage of bituminous mixture long distance transportation is suitable for bituminous mixture's long distance transportation, especially to the higher modified asphalt mixture of temperature that paves. To the temperature decline that bituminous mixture leads to in the long distance transportation, be unfavorable for the follow-up problem that paves and roll, the utility model discloses according to bituminous mixture's self characteristics, provide one kind and can realize heat retaining carriage and vehicle to the problem of the temperature decline that appears in having solved bituminous mixture long distance transportation, segregation, and then be favorable to bituminous paving's high quality to be paved.

The foregoing description of the exemplary embodiments of the invention has been presented for the purposes of illustration and description only. And it is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The preferred embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the following claims and their equivalents.
