Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and more specifically, it relates to an asphalt concrete paving device for asphalt pavement. Background Technology

[0002] In the construction of modern transportation infrastructure, the quality of roads plays a vital role in ensuring efficient, safe and smooth transportation. Asphalt concrete pavement is widely used in various road projects such as highways, urban roads and airport runways due to its advantages such as good smoothness, comfort, durability and anti-skid performance.

[0003] However, existing asphalt concrete paving equipment still has the following two shortcomings in use:

[0004] First, some feed silos lack effective guiding structures, which makes it easy for materials to segregate or accumulate when asphalt concrete is added to them. This can lead to blockages or discontinuous material supply during subsequent material transportation, reducing construction efficiency.

[0005] Secondly, while current paving machines have a certain compaction capacity after laying asphalt concrete, they lack sufficient adjustability and adaptability. They cannot flexibly adjust the compaction strength according to different paving thicknesses and material conditions, which affects the final road surface compaction quality. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an asphalt concrete paving device for asphalt pavements. This device solves the problems of existing paving machines lacking an effective guiding structure in their feed hoppers, leading to material segregation or accumulation, and the compaction mechanism lacking sufficient adjustability and adaptability, failing to flexibly adjust the compaction strength according to different paving thicknesses and material conditions.

[0007] The purpose and effect of this utility model of an asphalt concrete paving device for asphalt pavement are achieved by the following specific technical means: an asphalt concrete paving device for asphalt pavement, including a feeding hopper;

[0008] A device box is fixedly installed at the middle position of the bottom end face of the feeding hopper, and a through hole is opened on the surface of the left and right side plates of the feeding hopper respectively.

[0009] A drive motor is fixedly mounted on the outer end face of the front side plate of the device box. The front end of the drive motor is connected to a drive shaft, and the end of the drive shaft is rotatably connected to the rear side plate of the device box.

[0010] The conveying pipes are arranged symmetrically in two sets. The two conveying pipes are fixedly installed in the middle of the left and right side plates of the feeding hopper, and the conveying pipes are connected to the feeding hopper.

[0011] The connecting shaft is provided in two symmetrical sets, and one side of the outer end of the connecting shaft is rotatably connected to the outer end side plate of the conveying pipe.

[0012] The placement plate has a long strip-shaped structure. A connecting block is fixedly installed on the inner end face of the placement plate. The other end of the connecting block is fixedly connected to the feeding hopper. Through holes are evenly opened on the surface of the placement plate. A set of clamping mechanisms is installed on the surface of the placement plate.

[0013] Furthermore, the pressing mechanism includes: a pressure plate located directly below the placement plate, the main body of the pressure plate being a long strip structure, and an inclined front baffle installed on the front end face of the pressure plate; a fixing rod installed on the upper end face of the pressure plate, the fixing rod being slidably engaged in a through hole on the surface of the placement plate; and a connecting spring sleeved on the outside of the fixing rod, the upper end of the connecting spring being fixedly connected to the placement plate, and the lower end of the connecting spring being fixedly connected to the pressure plate.

[0014] Furthermore, a driving bevel gear is mounted on the surface of the drive shaft, and a driven bevel gear is fixedly mounted on one side of the inner end of the connecting shaft, with the driven bevel gear meshing with the driving bevel gear.

[0015] Furthermore, blades are fixedly installed on the outside of the connecting shaft. The blades have a spiral structure, and the outer end face of the blades is in contact with the inner end face of the conveying pipe.

[0016] Furthermore, a discharge port is fixedly installed on the lower end face of the conveying pipe, the inner end face of the conveying pipe is flush with the through hole on the surface of the left and right side plates of the feed hopper, and a cover plate with an inverted V-shaped top face is fixedly installed on the upper end face of the device box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, the front end of the device can be connected to a power unit. The asphalt concrete is first poured into the feed hopper, which serves as a container for storing and supplying asphalt concrete. The through holes on the left and right side plates provide channels for subsequent conveying. The cover plate installed on the upper end of the device box has an inverted V-shaped structure, which may help guide the material smoothly into the feed hopper and prevent the material from overflowing and accumulating during pouring.

[0019] Furthermore, through the meshing of the active bevel gear with the passive bevel gear on one side of the inner end of the connecting shaft, the rotational motion of the drive shaft is transmitted to the connecting shaft via the bevel gear transmission. The connecting shaft is fixedly installed with a helical blade, and the outer end face of the blade is in contact with the inner end face of the conveying pipe. When the connecting shaft rotates, the helical blade will push the asphalt concrete in the feed hopper into the conveying pipe through the through holes on the surface of the left and right side plates of the feed hopper. The helical structure of the helical blade can effectively transport the material from the feed hopper to the conveying pipe, realizing the horizontal conveying of the material.

[0020] In addition, the pressure plate is located directly below the placement plate. Its inclined front baffle can block and guide the material during the paving process. The fixing rod connects the pressure plate to the placement plate and slides in the through hole. At the same time, the connecting spring is sleeved on the outside of the fixing rod. The upper and lower ends of the connecting spring are fixedly connected to the placement plate and the pressure plate, respectively. When the paving device moves on the road surface, the pressure plate will be subjected to the reaction force of the road surface. At this time, the connecting spring can play a role in buffering and adjusting, so that the pressure plate can move up and down within a certain range, thereby generating pressure on the paved asphalt concrete and compacting it to improve the density of the asphalt concrete pavement.

[0038] The pressing mechanism includes: a pressure plate 6, located directly below the placement plate 5, the main body of the pressure plate 6 being a long strip structure, with an inclined front baffle 601 installed on the front end face of the pressure plate 6; a fixing rod 7, installed on the upper end face of the pressure plate 6, the fixing rod 7 being slidably engaged in the through hole 502 on the surface of the placement plate 5; and a connecting spring 701, sleeved on the outside of the fixing rod 7, the upper end of the connecting spring 701 being fixedly connected to the placement plate 5, and the lower end of the connecting spring 701 being fixedly connected to the pressure plate 6. The upper and lower ends of the connecting spring 701 are respectively fixedly connected to the placement plate 5 and the pressure plate 6. When the paving device moves on the road surface, the pressure plate 6 will be subjected to the reaction force of the road surface. At this time, the connecting spring 701 can play a buffering and adjusting role, allowing the pressure plate 6 to move up and down within a certain range, thereby generating pressure on the paved asphalt concrete and compacting it to improve the density of the asphalt concrete pavement.

[0039] Among them, a driving bevel gear 2011 is mounted on the surface of the drive shaft 201, and a driven bevel gear 402 is fixedly mounted on one side of the inner end of the connecting shaft 4. The driven bevel gear 402 meshes with the driving bevel gear 2011.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In this invention, the front end of the device can be connected to a power unit. Asphalt concrete is first poured into the feed hopper 1, which serves as a container for storing and supplying asphalt concrete. The through holes on the left and right side plates of the feed hopper 1 provide channels for subsequent conveying. The cover plate 1011 installed on the upper surface of the device box 101 has an inverted V-shaped structure, which may help guide the material smoothly into the feed hopper 1 and prevent overflow and accumulation during pouring. After the drive motor 2 starts, the active bevel gear 2011 on the surface of the drive shaft 201 rotates. Through the meshing of the active bevel gear 2011 with the passive bevel gear 402 on one side of the inner end of the connecting shaft 4, the rotational motion of the drive shaft 201 is transmitted to the connecting shaft 4 via the bevel gear transmission, causing the connecting shaft 4 to rotate. A spiral blade 401 is fixedly installed on the outside of the connecting shaft 4, and the outer end face of the blade 401 is in contact with the inner end face of the conveying pipe 3. When the connecting shaft 4 rotates, the spiral blade 401 pushes the asphalt concrete in the feed hopper 1 through the through holes on the left and right side plates of the feed hopper 1. Entering the conveying pipe 3, the spiral structure of the spiral blade 401 can effectively transport the material from the feed bin 1 to the conveying pipe 3, realizing the horizontal conveying of the material. After the material enters the conveying pipe 3, the asphalt concrete is discharged through the discharge port 301 at the lower end of the conveying pipe 3 for subsequent paving operations. During the paving process, the pressure plate 6 is located directly below the placement plate 5. The inclined front baffle 601 on its front end can play a certain role in blocking and guiding the material during the paving process. The fixing rod 7 connects the pressure plate 6 to the placement plate 5, and the fixing rod 7 is slidably locked in the through hole 502. At the same time, the connecting spring 701 is sleeved on the outside of the fixing rod 7. The upper and lower ends of the connecting spring 701 are fixedly connected to the placement plate 5 and the pressure plate 6, respectively. When the paving device moves on the road surface, the pressure plate 6 will be subjected to the reaction force of the road surface. At this time, the connecting spring 701 can play a buffering and adjusting role, so that the pressure plate 6 moves up and down within a certain range, thereby generating pressure on the paved asphalt concrete and compacting it to improve the density of the asphalt concrete pavement.
