[0023] Embodiment 1

[0024] As Figure 1 、 2 shown, a dump truck compartment includes a compartment main body. The compartment main body is a common dump truck compartment structure, including a compartment floor 1, compartment side plates 2 on both sides of the compartment floor 1, and a compartment front plate 3 at the front of the compartment floor 1. A heating system is provided in the compartment main body. The heating system includes an air inlet passage and a heating air passage. Specifically, relying on the structure of the compartment main body, air inlet interfaces 7 are respectively provided on both sides in front of the compartment front plate 3. The air inlet passage is arranged on both sides inside the compartment main body. There is an angle close to a right angle between the compartment floor 1 and the compartment side plates 2. An inclined plate 4 is provided at the connecting angle between the compartment floor 1 and the compartment side plates 2. Thus, the compartment floor 1, the compartment side plates 2, and the inclined plate 4 enclose a passage as the air inlet passage. The front end of the air inlet passage is communicated with the air inlet interface 7, and a first exhaust hole 9 is opened at the rear end of the air inlet passage.

[0025] As Figure 2As shown in the figure, the width of the carriage floor 1 is divided into left and right parts along the midline in the driving direction of the dump truck. A plurality of U-shaped beams 8 are respectively provided on both sides. The U-shaped beam 8 is a beam structure with a U-shaped cross-section (reference can be made to channel steel). The notch of the U-shaped beam faces upward, and thus a strip-shaped cavity is formed with the bottom surface of the carriage floor, serving as a heating air duct. On the bottom surface of the intake air duct, that is, on the carriage floor 1, a plurality of ventilation openings are provided along the length direction. Each ventilation opening corresponds to a U-shaped beam, and the ventilation opening communicates with the inside of the U-shaped beam, that is, the intake air duct is communicated with the heating air duct. It can be seen that the heating air duct (U-shaped beam) intakes air at one end close to the outside of the carriage, and the other end of the heating air duct is close to the midline of the carriage floor 1. On the left and right sides, no less than 5 U-shaped beams are provided, and the U-shaped beams at corresponding positions on both sides are arranged collinearly.

[0026] A plurality of flow splitting plates 5 are further provided in the intake air duct. The flow splitting plates 5 are arranged corresponding to the ventilation openings. The shape of the flow splitting plates 5 is adapted to the triangular cross-section of the intake air duct. The two side edges of the flow splitting plates are respectively welded to the carriage floor 1 and the carriage side plate 2. A window for the airflow to pass through is provided in the middle of the flow splitting plate 5. The airflow stagnates under the resistance of the flow splitting plate and can enter the heating air duct through the ventilation opening. A second exhaust hole can also be opened at the inner end of the heating air duct to improve the airflow efficiency in the heating air duct. At the same time, the flow splitting plate also serves as a reinforcing rib in the intake air duct to improve the strength of the inclined plate 4.

The exhaust system includes components from the engine to the post-processor, as well as the exhaust pipe, etc. (this is the original exhaust system of the dump truck and will not be elaborated here). The exhaust port of the exhaust system is connected to the intake interface 7, that is, the front end of the intake air duct. Considering the flipping function of the carriage, a flexible and telescopic structure, such as a metal bellows, should be adopted between the exhaust port and the intake interface 7.

[0029] It can be seen from the above embodiments that the beneficial effects of the present utility model are as follows: By using the exhaust gas discharged from the engine, multiple horizontally arranged heating air ducts are arranged in the front and rear rows on the bottom surface of the carriage floor, which improves the distribution density of the heating system, makes the carriage heating more uniform, and improves the heating effect; This solution relies on the heating structure setting, realizes guiding the airflow while also taking into account the strengthening effect of the carriage structure, improves the carriage structure strength, and reduces the carriage cost through the design of multi-purpose use of one component.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model.
