Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a dump truck for asphalt construction. Background Art

[0002] Paving asphalt is a commonly used road paving material composed of asphalt and mineral materials. It has excellent durability and can withstand the long-term effects of vehicle traffic and the natural environment. Paving asphalt has elasticity and deformation capabilities, can reduce vibrations on the road, and provide a smooth driving and walking experience. It is widely used in road construction and maintenance.

[0003] When transporting paving asphalt, dump trucks are usually required. Dump trucks are vehicles specially designed to transport and unload various materials. When it comes to paving asphalt, dump trucks can provide an efficient and convenient way to transport asphalt from the production plant or concrete mixing plant to the construction site. The unloading system of the dump truck will tilt or lift the car body, allowing the asphalt to be quickly dumped out from the bottom of the car body.

[0004] However, in actual use of the above equipment, dump trucks can only transport asphalt. After unloading the asphalt, paving machinery is still needed to evenly spread the mixture on the road base. If a dump truck can complete paving while unloading the asphalt, the efficiency of asphalt paving can be greatly improved. In view of this, we propose a dump truck for asphalt construction. Summary of the invention

[0005] The purpose of the utility model is to provide a dump truck for asphalt construction to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a dump truck for asphalt construction, comprising a dump truck body, a hopper is arranged on the top of the dump truck body, the inner wall of the hopper is hinged to a baffle plate, a paving assembly is arranged on the top end surface of the baffle plate, and the paving assembly is provided with:

[0007] Baffle 2, the top end surface of the baffle 1 is fixedly connected with an electric push rod, and the output end of the electric push rod is fixedly connected with baffle 2;

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a dump truck for asphalt construction, including a dump truck body 1, a hopper 2 is arranged on the top of the dump truck body 1, the inner wall of the hopper 2 is hinged with a baffle 3, and a paving assembly is arranged on the top end face of the baffle 3, and the paving assembly is provided with an electric push rod 4, a baffle 5, an arc guide plate 6, a motor 7, a worm 8, a rotating shaft 9, a worm wheel 10, a vertical rod 11, a horizontal rod 12, a leveling plate 13 and a guide plate 14.

[0025] In one embodiment of the utility model, the top end surface of the baffle 1 3 is fixedly connected to an electric push rod 4, the output end of the electric push rod 4 is fixedly connected to a baffle 2 5, the outer wall of the baffle 2 5 is fixedly connected to an arc guide plate 6, the arc guide plate 6 guides the asphalt coming out of the hopper 2 to prevent the asphalt from pouring behind the guide plate 14, the outer wall of the hopper 2 is rotatably connected to a rotating shaft 9, the side wall of the rotating shaft 9 is fixedly connected to a worm gear 10, the side wall of the rotating shaft 9 is fixedly connected to one end of a vertical rod 11, and the other end of the vertical rod 11 is fixed to a horizontal rod 12 The hopper 2 is fixedly connected to a motor 7 on its outer wall, a worm 8 is fixedly connected to the output end of the motor 7, the worm 8 cooperates with the worm wheel 10, the worm 8 rotates to drive the worm wheel 10 to rotate, the cross bar 12 is hinged to the leveling plate 13, both ends of the leveling plate 13 are fixedly connected to guide plates 14, the guide plates 14 are tilted to guide excess asphalt to both sides of the road, both ends of the leveling plate 13 are fixedly connected to balance plates 15, the balance plates 15 and the guide plates 14 are symmetrically arranged so that the center of gravity of the leveling plate 13 is located at the center of the leveling plate 13.

[0026] The hopper 2 is lifted, and the electric push rod 4 pulls the baffle plate 2 5 to move upward, so that the asphalt in the hopper 2 can be discharged, and the motor 7 starts to drive the worm 8 to rotate, the worm 8 rotates the worm wheel 10 to rotate, and the rotation of the worm wheel 10 drives the rotating shaft 9 to rotate, and further drives the vertical rod 11 and the cross bar 12 to rotate around the rotating shaft 9, so that the leveling plate 13 is located behind the asphalt discharge port. Since the connection part between the leveling plate 13 and the cross bar 12 is higher, the center of gravity of the leveling plate 13 is lower than the connection part between the leveling plate 13 and the cross bar 12, and then due to the effect of gravity, the leveling plate 13 is always perpendicular to the ground, the dump truck body 1 moves forward, and the asphalt is discharged along the direction of the dump truck body 1, and then the leveling plate 13 levels the asphalt, and the excess asphalt is guided to both sides of the road along the guide plate. At the same time, the outer wall of the baffle plate 2 5 is fixedly connected with an arc guide plate 6, and the arc guide plate 6 guides the asphalt coming out of the hopper 2 to prevent the asphalt from pouring to the rear of the guide plate 14.

[0027] In addition, in order to balance the center of gravity of the leveling plate 13, balancing plates 15 are fixedly connected to both ends of the leveling plate 13. Since guide plates 14 are installed on both sides of the leveling plate 13, the center of gravity of the leveling plate 13 is shifted forward. The balancing plate 15 and the guide plate 14 are symmetrically arranged, so that the center of gravity of the leveling plate 13 is located at the center of the leveling plate 13, which better balances the weight distribution of the leveling plate 13, ensures the stability and flatness of the leveling plate 13 during work, and provides a more uniform paving effect.

[0028] In the utility model, when in use, the hopper 2 is lifted, the electric push rod 4 pulls the baffle plate 2 5 to move upward, so that the asphalt in the hopper 2 can be discharged, the motor 7 is started, so that the leveling plate 13 is located behind the asphalt unloading port, the dump truck body 1 moves forward, and the asphalt is discharged along the direction of the dump truck body 1. Then the leveling plate 13 levels the asphalt, and the excess asphalt is guided to both sides of the road along the guide plate. The balance plate 15 and the guide plate 14 are symmetrically arranged, so that the center of gravity of the leveling plate 13 is located at the center of the leveling plate 13, ensuring the stability and flatness of the leveling plate 13 during work, and providing a more uniform paving effect.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
