[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Please refer to Figures 1 to 5 As shown, the embodiment of the utility model provides a mining vehicle, including a frame assembly 1 and a cargo box assembly 2. Specifically, as Figure 1 As shown, the cargo box assembly 2 is installed on the frame assembly 1. Specifically, the cargo box assembly 2 is connected to the rear end of the frame assembly 1 through a flip seat, so that the cargo box assembly 2 can be flipped to unload stones and the like. Figure 4 As shown, the cargo box assembly 2 includes a cargo box body 21 and a brim 22 which are separately arranged, so that the cargo box body 21 can be assembled on the whole vehicle, and the brim 22 can be used as a separate accessory of the whole vehicle. The brim 22 and the cargo box body 21 can be detachably connected, for example, by a bolt assembly, so that the brim 22 and the cargo box body 21 can be assembled conveniently after arriving at the mining site.

[0042] In this way, the cargo box assembly 2 can be assembled separately, and the brim 22 can be shipped as a vehicle accessory without removing the vehicle tires, so as to ensure that the height of the vehicle meets the shipping requirements, which is convenient for road transportation and easy to operate. Figure 1For the placement of the mining vehicle shown in the figure, the direction indicated by the solid arrow in the figure is the front and rear direction.

[0043] In some embodiments of the present invention, the mining vehicle further comprises a cab assembly 3, such as Figure 1 As shown, the cab assembly 3 is arranged on the frame assembly 1. Specifically, the cab assembly 3 includes a cab body 31 and a platform assembly 32. Figure 3 As shown, the cab body 31 and the platform assembly 32 are arranged side by side along the width direction of the mining vehicle, and the width of the cab body 31 is less than half of the width of the mining vehicle. Specifically, the cab body 31 is fixed to the left front side of the frame assembly 1 through the cab suspension assembly, wherein the cab suspension assembly is located at the front and rear ends of the cab body 31. The right side of the cab body 31 is the platform assembly 32, and the platform assembly 32 is fixed to the right front side of the frame assembly 1 through the platform suspension assembly, wherein the platform suspension assembly is located at the front and rear ends of the platform assembly 32. It should be noted that, as shown in FIG. Figure 1 and Figure 3 For the placement position of the mining vehicle shown in the figure, the direction indicated by the solid arrow in the figure is the front-rear direction, and the direction indicated by the hollow arrow in the figure is the left-right direction and the width direction.

[0044] With such arrangement, the cab body 31 forms a narrow cab, which can save costs to a certain extent while ensuring the driving space requirements, and leaves sufficient operation and maintenance space for the right platform, so that inspection and maintenance can be easily carried out without turning over the cab. At the same time, the rear view is good, which is conducive to driving in the mining area. In addition, if Figure 3 As shown, the lower ends of the cab body 31 and the platform assembly 32 are provided with a bumper 33, which is fixedly mounted on the frame assembly 1, for example, on the first crossbeam 12. The material of the bumper 33 is fiberglass, which is safe and reliable while being more cost-effective. In addition, the front windshield of the cab body 31 is set to a forward tilting structure to provide a better driving field of vision. It should be noted that Figure 3 For the placement of the mining vehicle shown in the figure, the up and down directions in the figure are the upper and lower directions.

[0045] In some embodiments of the present invention, Figure 1As shown, the cab assembly 3 is located at the front end of the cargo box assembly 2, and the brim 22 extends to the top of the cab assembly 3. And along the length direction of the mining vehicle, the extension length of the brim 22 is greater than or equal to the length of the cab assembly 3. With this arrangement, the brim 22 can completely cover the top of the cab body 31. When the mining vehicle is loaded, the falling stones are first blocked by the brim 22 of the cargo box assembly 2, which prevents the cab assembly 3 from being directly hit by the falling stones, thereby protecting the driver and the cab assembly 3, so as to reduce the failure rate of the product. It should be noted that, as shown in the figure, Figure 1 For the placement of the mining vehicle shown in the figure, the direction indicated by the solid arrow in the figure is the length direction.

Specifically, the power system 4 includes an engine assembly 41, and the engine assembly 41 includes an engine, and the power of the engine is greater than or equal to 560kw. In this arrangement, since a high-horsepower engine is used, and its power reaches 560kw or more, no post-processing is required, the emission requirements of dump trucks are met, the traditional urea device is eliminated, the operating cost of the mining area is reduced, and the risk of post-processing failure is reduced.

[0047] In some embodiments of the utility model, the engine assembly 41 is arranged below the platform assembly 32. The engine assembly 41 also includes an engine suspension assembly, through which the engine assembly 41 is connected to the frame assembly 1. Specifically, the engine suspension assembly is respectively arranged at the front end of the engine cylinder block and the flywheel housing. With such an arrangement, the platform assembly 32 can be opened when checking the engine, which is convenient for the maintenance and replacement of the engine.

[0048] In some embodiments of the present invention, Figure 5 As shown, the power system 4 also includes an exhaust component 42, and the exhaust component 42 is arranged at the exhaust end of the engine. The exhaust component 42 includes an exhaust conversion box, and the exhaust conversion box is used to change the flow direction of the engine's exhaust gas. Specifically, the engine exhaust gas can be used for direct exhaust and cargo box heating, respectively, so that the cargo box floor can be heated by the exhaust gas, so as to effectively prevent stones from freezing to the cargo box floor in winter. With such an arrangement, since no post-processing is required, sufficient installation space is provided for the arrangement of the exhaust conversion box, and the exhaust gas is better sealed by ventilation through the exhaust conversion box. In addition, the exhaust component 42 also includes an exhaust bellows and an exhaust steel pipe, wherein the exhaust bellows can be used to absorb the vibration of the engine. In addition, as Figure 5 As shown, the power system 4 also includes a heat dissipation component 43, a fuel component 44 and an air intake component 45, wherein the heat dissipation component 43 is located at the front end of the engine to dissipate the heat of the engine body. They each play a key role and jointly ensure the stable operation and high efficiency performance of the power system 4.
