Description

Technical Field

[0001] The utility model belongs to the technical field of dump truck cargo compartments, and in particular relates to an exhaust structure at the rear of a dump truck bottom plate. Background Art

[0002] Mining dump trucks are one of the most important equipment in open-pit mining and large-scale earthwork construction. They are mainly used to transport various loose materials. During winter transportation, loose materials containing moisture will freeze and stick to the bottom of the cargo compartment and cannot be unloaded.

[0003] To prevent materials from freezing in the cargo compartment, wide-body dump trucks use a bottom plate heating method that heats the triangular connecting plates between the bottom plate, side plate, and front plate to improve the vehicle's dumping performance in winter. However, this method has low thermal efficiency. At present, in order to improve the utilization rate of exhaust gas, the vehicle's exhaust gas is usually passed into the longitudinal beam to heat the bottom plate to improve the dumping performance.

[0004] However, since the exhaust gas needs to be discharged from the rear part of the floor after the longitudinal beam is heated, in order to allow the hot gas to flow, a reasonable connecting structure is needed to guide the exhaust gas. In the past, a cross beam was usually directly set at the rear end of the longitudinal beam to seal the longitudinal beam. This method makes it difficult to achieve the circulation of exhaust gas. In order to ensure the normal circulation of exhaust gas, the rear part of the longitudinal beam on the floor of some vehicles is opened, and the exhaust gas flows out directly. This method causes the exhaust gas to not last long enough. During driving, the exhaust gas is easily discharged at a larger flow rate, and the structural strength of the car body cannot be guaranteed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an exhaust structure at the rear of a dump truck bottom plate, which is used to solve the problem of poor exhaust effect of a cargo compartment bottom plate.

[0006] The utility model solves the above technical problems with the following technical solutions: a dump truck bottom plate tail exhaust structure, comprising:

[0007] A plurality of cross beam sections, wherein a plurality of air inlet holes corresponding to the ends of the longitudinal beams are opened on a side of the cross beam section close to the longitudinal beam, and an air outlet hole is opened at the bottom of the cross beam section;

[0008] At least two hook seats are provided, the hook seats are spaced apart, and two sides of the hook seats abut against the ends of the cross beam sections.

[0009] Compared with the prior art, the above technical solution has the following beneficial effects:

[0010] An exhaust structure composed of multiple cross beam sections and hook seats is fixed on the tail of the longitudinal beam at the bottom of the dump truck. It blocks the tail of the longitudinal beam and plays an exhaust role at the same time. An air inlet is opened on the side of the cross beam section close to the longitudinal beam, and the exhaust gas passes through the hollow channel of the cross beam section and is discharged from the air outlet at the bottom, which increases the retention time of the exhaust gas. At the same time, a position is reserved for the hook seat. The cross beam section and the hook seat are abutted to form a whole, which strengthens the tail of the bottom plate and plays an exhaust role at the same time.

[0011] Further, the cross beam section includes a bottom plate section; and

[0012] The two bending sections are connected to the two side edges of the bottom plate section to form a U-shaped structure with an opening connected to the bottom plate.

[0013] Furthermore, the bent sections in the two outer cross beam sections extend outward to form a cantilevered section, and a reinforcing section having one end connected to the bottom plate section is sealed at the bottom of the cantilevered section.

[0014] Furthermore, the outer end of the reinforcement section is inclined upward.

[0015] Furthermore, it also includes a plurality of reinforcing plates, wherein the first side edges of the reinforcing plates are connected to the side edges of the hook seats, and the second side edges of the reinforcing plates are connected to the surface of the cross beam section.
