Description

A heavy-duty dump truck bucket

Technical field

The utility model relates to the technical field of transport vehicles, in particular to a heavy-duty dump truck bucket.

Background technique

A dump truck refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device. The cabin of a dump truck is divided into two types: backward tipping and sideways tipping. The movement of the piston rod is controlled by the operating system. Rearward tipping is more common. Pushing the piston rod causes the cabin to tip. Dump trucks often work together with excavators, loaders, belt conveyors and other engineering machinery in civil engineering to form a loading, transporting and unloading production line to carry out the loading and unloading of earthwork, sand and gravel, and bulk materials.

At present, most of my country's larger open-pit mines use large-tonnage heavy-duty dump trucks when transporting loads, with a load capacity between 100 tons and 330 tons. During the process of frequent loading and unloading of materials, the dump truck bucket impacts the bottom plate of the bucket. And wear is the most serious, and repairing after wear is also more time-consuming and laborious.

At this stage, heavy-duty dump trucks usually adopt a straight floor design structure and are paved with wear-resistant plates with a Brinell hardness of about 500. However, when unloading materials, the bucket needs to be lifted to a certain height for unloading operation. At this time, the entire material begins to rub and slide along the bottom plate of the dump truck bucket. The pressure of the material itself is too high, resulting in excessive friction with the bottom plate. Causes serious wear to the bottom plate.

Referring to Figure 1, a heavy-duty dump truck bucket includes a support part and a reinforcing part 200. Among them, the support part includes a front baffle 110, a side baffle 120, a front bottom plate 130, a rear bottom plate 140, a rear baffle 150 and a compartment hat brim 160. The front bottom plate 130 and the rear bottom plate 140 are fixedly connected. The rear bottom plate 140 is tilted upward and forms an acute angle with the front bottom plate 130 . The front baffle 110 is disposed on the opposite side of the rear bottom plate 140 and is fixedly connected to the front bottom plate 130 . Two side baffles 120 are fixedly connected to the remaining two sides of the front bottom panel 130 , and the bottom edges of the side baffles 120 are fixedly connected to the front bottom panel 130 and the rear bottom panel 140 . The front bottom plate 130, the rear bottom plate 140, the front baffle 110 and the side baffles 120 are of an integrated structure and form a box that can accommodate materials.

In some specific embodiments of the present invention, a tailgate 150 is also included. The rear door 150 is arranged at the rear end of the rear bottom plate 140, and is rotatably linked to the two side baffles 120 on both sides. It can rotate along the fixed axes of the side baffles 120 to control the opening and closing of the interior of the compartment. When the dump truck is fully loaded and unloading, the rear door 150 is in a closed state. After the upper material slides down first, the rear door 150 is slowly opened and the lower material begins to slide. It can speed up the dump truck's unloading speed of lower materials.

In some specific embodiments of the present invention, the angle between the horizontal plane where the front floor 130 is located and the rear floor 140 is 60°. Using this angle, when the dump truck is unloading and the bucket is lifted to a certain height by the hydraulic device, the upper material in the bucket begins to slide due to gravity. At this time, the sliding process can be regarded as only the lower surface of the upper material and the lower part of the bucket. Friction occurs between the upper surfaces of the materials, thereby preventing friction damage to the bottom plate of the bucket.

In some specific embodiments of the present invention, a bucket brim 160 is also provided on the top of the front baffle 110 . The brim 160 of the compartment bucket has a plate-shaped structure and is provided with protrusions around it to intercept dumped materials. The bucket brim 160 is fixedly connected to the front baffle 110 and is used to protect the safety of the cab and prevent materials from toppling in the direction of the cab due to bumps during transportation, causing safety accidents.

With reference to Figures 1 and 2, the heavy-duty dump truck bucket of the present utility model is also provided with a reinforcing portion 200. The reinforcing portion 200 is fixedly connected to the lower surfaces of the front bottom plate 130 and the rear bottom plate 140 and includes a reinforcing spine 210 disposed in the middle of the lower surface and parallel to the body length direction, and a plurality of reinforcing ribs 220 perpendicular to the reinforcing spine 210 . Among them, there are a plurality of reinforcing ribs 220, which are arranged transversely perpendicular to the reinforcing spine 210, and two sections extend to the side baffle 120 to protect the stability of the overall structure and enhance the rigidity of the compartment. The reinforcing ribs 220 are used to increase the stability of the overall structure. This solution has a simple structure and strong load-bearing capacity, and can increase the service life of the entire box.

As shown in FIG. 2 and FIG. 3 , in some specific embodiments of the present invention, three reinforcing spines 210 are provided, among which the first reinforcing spine is provided at the middle position of the lower surface of the front bottom plate 130 and is arranged along the length direction of the bucket body. To enhance the overall load-bearing capacity and stabilize the overall structure. Second reinforcing spines are respectively provided on both sides of the first reinforcing spine. The second reinforcing spines extend along the front bottom plate 130 to the rear bottom plate 140 for stabilizing the overall structure. Because the rear bottom plate 140 is upturned, the connection structure is unstable. When the weight of the load-bearing object is too heavy, the overall stress is concentrated on the connection part of the rear bottom plate 140, which will cause the overall structure to be unstable. Therefore, adding two second reinforcing spines can effectively strengthen the structure. The load-bearing capacity of the rear bottom plate 140 stabilizes the overall structure.

Referring to Figure 3, in some specific embodiments of the present invention, a heating part 300 is also included. The heating part 300 includes a smoke exhaust channel, an exhaust gas inlet 310 and an exhaust gas exhaust port 330.

In some embodiments, smoke exhaust channels are provided in the reinforced spine 210 . This design can reduce the overall weight caused by the pipeline design, which leads to the problem of excessive transmission pressure. The smoke exhaust duct 320 is buried in the reinforced spine 210, and the limited space is rationally 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 beautiful.

In some specific embodiments, the exhaust air inlet 310 is disposed on the lower bottom surface of the front floor 130 on the side closer to the front fender 110 , and the exhaust exhaust port 330 is disposed on the lower bottom surface of the front floor 130 closer to the rear floor 140 . The exhaust gas inlet 310 is connected with the engine exhaust port. The exhaust gas generated during the operation of the dump truck enters through the exhaust gas inlet 310 , passes through the smoke exhaust pipe 320 , and is finally discharged through the exhaust gas exhaust port 330 . During this process, the residual temperature of the exhaust gas can be used to heat and keep the entire front bottom plate 130 warm.

In some of the specific embodiments, the exhaust gas in the heating part 300 flows evenly through the entire front baffle 110, and the temperature of the exhaust gas is used to heat the compartment body. The waste heat of the exhaust gas is rationally used to heat the bottom of the compartment to prevent the transportation materials from freezing due to weather conditions and making it difficult to unload due to sticking to the compartment during the unloading process.

The working principle of the present utility model is explained with reference to Figures 4 and 5. FIG. 4 is a schematic diagram of the connection between the rear bottom plate 140 and the front bottom plate 130 of the present invention at an acute angle. When the whole bucket is lifted by hydraulic drive, the rear bottom plate 140 is upturned to form a stable support structure. As a result, when the bucket tilts, the loaded upper materials begin to slide down first. At this time, it can be seen that only the lower surface of the upper material and the upper surface of the lower material have frictional motion, which will not cause serious friction damage to the bottom plate of the bucket. When the upper material slides down, the rear door 150 is opened to accelerate the unloading process of the lower material. At this time, because the overall weight of the loaded materials is reduced, when the lower material slides down, the friction on the bucket bottom plate is reduced, and the wear of the bucket bottom plate will also be relatively reduced.

As shown in Figure 5, it is a schematic diagram of the exhaust gas circulation of the heating part 300 of the present invention. The dump truck exhaust enters the smoke exhaust duct 320 through the exhaust air inlet 310, merges from both sides to the middle, then branches from the middle to both sides, and is finally discharged along the exhaust outlet 330. During the process, the entire bottom plate of the compartment can be heated, and the heating effect will not be poor due to a fixed flow direction. This kind of pipeline design can effectively prevent the cargo from freezing due to the bucket working in cold conditions.
