The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Referring to fig. 1, a heavy dump truck bucket includes a support portion and a reinforcement portion 200. The support includes, among other things, a front baffle 110, side baffles 120, a front floor 130, a rear floor 140, a rear baffle door 150, and a car visor 160. The front base plate 130 and the rear base plate 140 are fixedly connected, and the rear base plate 140 is tilted upward to form an acute angle with the front base plate 130. The front barrier 110 is disposed at an opposite side of the rear chassis 140, and is fixedly coupled to the front chassis 130. Two side baffles 120 are fixedly connected to the remaining two sides of the front bottom plate 130, and the bottom edges of the side baffles 120 are fixedly connected with the front bottom plate 130 and the rear bottom plate 140. The front floor 130, rear floor 140, front baffles 110 and side baffles 120 are of unitary construction forming a box that can hold load bearing materials.

In some embodiments of the present utility model, a rear shutter 150 is also included. The rear door 150 is disposed at the rear end of the rear chassis 140, and rotatably links with the two side baffles 120 at both sides thereof, and is rotatable along a shaft fixed to the side baffles 120 to control the opening and closing of the inside of the car hopper. When the dump truck is fully loaded and unloaded, the rear shutter 150 is in a closed state, and after the upper material slides down in advance, the rear shutter 150 is slowly opened, and the lower material starts to slide down. The speed of unloading the lower material of the dump truck can be increased.

In some embodiments of the present utility model, the front floor 130 is positioned at a 60 angle from the rear floor 140. By adopting the angle, when the dump truck discharges, and the carriage bucket is lifted to a certain height by the hydraulic device, the upper material in the carriage bucket starts to slide down due to gravity, and the sliding process can be regarded as friction between the lower surface of the upper material and the upper surface of the lower material only, so that friction damage to the carriage bucket bottom plate can not be generated.

In some embodiments of the present utility model, the top end of the front baffle 110 is also provided with a car visor 160. The carriage cap peak 160 is of a plate type structure, and bulges are arranged on the periphery of the carriage cap peak to intercept the poured materials. The car cap peak 160 is fixedly connected to the front baffle 110 for protecting the cab from being fallen down in the cab direction due to jolt during transportation, thereby preventing safety accidents.

Referring to fig. 1 and 2, the heavy duty dump truck bucket of the present utility model is further provided with a reinforcement 200. The reinforcement part 200 is fixedly coupled to the lower surfaces of the front and rear chassis 130 and 140, and includes a reinforcement rib 210 disposed at the middle of the lower surface and parallel to the length direction of the body, and a plurality of reinforcement ribs 220 disposed perpendicular to the reinforcement rib 210. Wherein, the reinforcing ribs 220 are arranged transversely and perpendicularly to the reinforcing back 210, and two sections extend to the side baffle 120 for protecting the stability of the whole structure and reinforcing the rigidity of the carriage bucket. The reinforcing ribs 220 are used for improving the stability of the whole structure, the scheme is simple in structure and high in bearing capacity, and the service life of the whole car hopper can be prolonged.

As shown in fig. 2 and 3, in some embodiments of the present utility model, the reinforcing ridges 210 are provided in 3, wherein the first reinforcing ridges are provided at the middle position of the lower surface of the front floor 130, and are disposed along the longitudinal direction of the car hopper body, so as to enhance the overall load bearing capacity and stabilize the overall structure. Second reinforcing ridges are respectively provided at both sides of the first reinforcing ridge, and extend along the front chassis 130 to the rear chassis 140 for stabilizing the overall structure. Because of the back bottom plate 140 upwarps, the structure of the joint is unstable, when the weight of the load-carrying object is overweight, the integral stress is concentrated at the joint of the back bottom plate 140, and the integral structure is unstable, so that the load-bearing capacity of the back bottom plate 140 can be effectively enhanced by adding two second reinforced ridges, and the integral structure is stabilized.

Referring to fig. 3, in some embodiments of the present utility model, a heating part 300 is further included. The heating part 300 includes a smoke exhaust passage, an exhaust gas inlet 310, and an exhaust gas outlet 330.

In some embodiments, the smoke evacuation channels are disposed in the stiffening spine 210. The design can reduce the overall weight caused by the design of the pipeline, and the problem of overlarge transmission pressure is caused. The smoke exhaust duct 320 is buried in the reinforced spine 210, and the limited space is reasonably utilized, so that the smoke exhaust duct 320 is closer to the front bottom plate 130, the heating effect is better, and the overall design is attractive.

In some embodiments, the exhaust gas inlet 310 is disposed on a side of the lower bottom surface of the front chassis 130 adjacent to the front baffle 110, and the exhaust gas outlet 330 is disposed on a side of the lower bottom surface of the front chassis 130 adjacent to the rear chassis 140. The exhaust gas inlet 310 is connected with an engine exhaust port, and exhaust gas generated in the operation process of the dump truck enters through the exhaust gas inlet 310, passes through the exhaust gas pipeline 320 and finally is discharged through the exhaust gas outlet 330. In this process, the whole front bottom plate 130 can be heated and insulated by utilizing the residual temperature of the tail gas.

In some embodiments, the exhaust gas from the heating portion 300 flows uniformly through the entire front baffle 110, and the temperature of the exhaust gas is used to heat the bucket body. The tail gas waste heat is reasonably utilized to heat the bottom of the carriage bucket, so that the problem that the carrying materials are frozen due to weather reasons and are difficult to adhere to the carriage bucket for unloading in the unloading process is solved.

The working principle of the utility model is elucidated with reference to fig. 4 and 5. Fig. 4 is a schematic diagram of a link in which the rear chassis 140 and the front chassis 130 form an acute angle. When the whole car is lifted by hydraulic drive, a stable supporting structure is formed due to the upwarp of the rear bottom plate 140, and the loaded upper material begins to slide down when the car tilts. At the moment, the friction motion between the lower surface of the upper material and the upper surface of the lower material can be considered to occur, so that the bottom plate of the bucket can not be seriously damaged by friction. When the upper material slides down, the rear shutter 150 is opened, accelerating the unloading process of the lower material. At this time, because the weight of the whole loaded material is reduced, when the lower material slides down, the friction force to the bottom plate of the carriage bucket is reduced, and meanwhile, the abrasion of the bottom plate of the carriage bucket is also relatively reduced.

Fig. 5 is a schematic diagram showing the tail gas circulation of the heating unit 300 according to the present utility model. The tail gas of the dumper enters the smoke exhaust pipeline 320 through the tail gas inlet 310, is converged from two sides to the middle, is split from the middle to two sides, and is finally discharged along the tail gas outlet 330. In-process can wholly heat the railway carriage or compartment bucket bottom plate, can not be because of the flow direction is fixed, leads to the condition of heating effect not good to appear. The pipeline design can effectively prevent the problem that the cargo is frozen due to the fact that the carriage bucket works under the cold condition.
