Description

Technical Field

[0001] This utility model belongs to the field of paver technology, specifically relating to an asphalt concrete paver. Background Technology

[0002] In road construction and maintenance projects, asphalt concrete paving is a crucial step, as its paving quality directly affects the road's service life, driving comfort, and safety.

[0003] For example, CN 213389607 U discloses an asphalt concrete paver, including a main body, a hopper disposed on one side of the main body, a feeding pipe connected to the main body on the side wall of the hopper, a scraper, a drive unit, and a spraying assembly. The scraper is slidably connected to the hopper, the drive unit drives the scraper to slide on the hopper, and the spraying assembly is located at one end of the scraper's sliding path and is used to clean the scraper. After the road paving is completed, the scraper is first used to scrape the asphalt adhering to the hopper off the hopper. Then, the scraper is brought close to the spraying assembly, which is connected to an external water source and sprays the scraper to wash off the asphalt adhering to it. Compared to directly washing the entire hopper, this method has higher cleaning efficiency, consumes more water, and achieves a high-efficiency and energy-saving effect.

[0004] In actual use, the above-mentioned cases show that the stability of the walking system is not good, and it is prone to slipping and bumping under complex road conditions, which affects the continuity and uniformity of paving. At the same time, the steering is not flexible enough, and the operation is difficult in narrow spaces or when the construction direction needs to be frequently adjusted, which reduces the construction efficiency. Therefore, this utility model provides an asphalt concrete paver. Utility Model Content

[0005] The purpose of this invention is to provide an asphalt concrete paver to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an asphalt concrete paver, comprising a frame, with walking components provided at each of the four corners of the frame, a hopper fixedly connected to the top of the frame, a rotating auger provided at the bottom of the hopper, and a paving plate provided on one side of the inner cavity of the frame, the paving plate being I-shaped.

[0007] In a preferred embodiment, the bottom of the hopper is provided with a diversion plate, the rotating auger is located directly below the diversion plate, and the frame is provided with baffles on both sides of the rotating auger.

[0008] In a preferred embodiment, a drive motor is fixedly connected to one side of the inner cavity of the frame, a drive gear is provided on the output shaft of the drive motor, a driven gear is provided at one end of the rotating auger, and the drive gear and the driven gear are connected by a transmission belt.

[0009] In a preferred embodiment, hydraulic lifting rods are fixedly connected to both sides of the inner cavity of the frame. The telescopic ends of the hydraulic lifting rods are fixedly connected to the top of the paving plate. A vibration motor is provided on the top of the paving plate, and the paving plate is located on one side of the rotating auger.

[0010] In a preferred embodiment, the walking assembly includes a connecting frame bolted to the frame, a hydraulic telescopic rod fixedly connected to the end of the connecting frame, a fixed frame rotatably connected to the bottom end of the hydraulic telescopic rod, and walking rollers rotatably connected to both ends of the fixed frame, with walking tracks provided on the outside of the two walking rollers.

[0011] In a preferred embodiment, a steering hydraulic rod is rotatably connected to the bottom of the connecting frame, and the other end of the steering hydraulic rod is rotatably connected to the top of the fixed frame.

[0012] In a preferred embodiment, a walking motor is fixedly connected to the top of the connecting frame, and a drive disk is provided on the output shaft of the walking motor. The outside of the drive disk is connected to one end of a walking roller via a connecting belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The use of hydraulic telescopic rods and fixed frames in this asphalt concrete paver allows the paver to flexibly adjust its travel height according to different road conditions, enhancing its passability and stability in complex terrain. The steering hydraulic rods give the paver flexible steering capabilities, enabling easy steering operations in narrow spaces or when frequent adjustments to the construction direction are required, reducing downtime and adjustment time during construction and improving construction efficiency.

[0015] This asphalt concrete paver effectively solves the problem of uneven asphalt concrete delivery by setting up a diversion plate at the bottom of the hopper and baffles on both sides of the rotating auger. The diversion plate guides the asphalt concrete in the hopper to flow smoothly and orderly to the rotating auger, ensuring the continuity and uniformity of material delivery and avoiding uneven paving thickness caused by material accumulation or flow interruption. At the same time, the baffles prevent asphalt concrete from overflowing during delivery, reducing material waste and improving construction efficiency.

[0016] This asphalt concrete paver features an I-beam paving slab design. This unique shape enhances the structural strength of the paving slab, enabling it to better withstand the impact and pressure of asphalt concrete during paving, making it less prone to deformation. Furthermore, the I-beam paving slab can more effectively level and compact the asphalt concrete during paving operations, improving the smoothness and density of the paved layer, thereby enhancing the road's resistance to rutting and its service life.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-3 This utility model provides an asphalt concrete paver, including a frame 1. Each of the four corners of the frame 1 is provided with a walking component 3. The walking component 3 includes a connecting frame 301 bolted to the frame 1. A hydraulic telescopic rod 304 is fixedly connected to the end of the connecting frame 301. A fixed frame 303 is rotatably connected to the bottom end of the hydraulic telescopic rod 304. Both ends of the fixed frame 303 are rotatably connected with walking rollers 306. Walking tracks 307 are provided on the outside of the two walking rollers 306. A steering hydraulic rod 302 is rotatably connected to the bottom of the connecting frame 301. The other end of the steering hydraulic rod 302 is rotatably connected to the top end of the fixed frame 303. A walking motor 305 is fixedly connected to the top of the connecting frame 301. A drive disc is provided on the output shaft of the walking motor 305. The outside of the drive disc is connected to one end of a walking roller 306 through a connecting belt 308.

[0024] When the paver needs to move forward or backward, the travel motor 305 is started. The output shaft of the travel motor 305 starts to rotate, driving the drive disc to rotate. Since the drive disc is connected to one end of a travel roller 306 through a connecting belt 308, the rotation of the drive disc will transmit power to the travel roller 306 through the connecting belt 308, causing it to start rotating. After the travel roller 306 rotates, it will drive the travel track 307 to move. The travel track 307 and the other travel roller 306 also cooperate with each other, driving the other travel roller 306 to rotate through friction, thereby realizing the movement of the entire paver.

[0025] When the paver needs to turn, the steering hydraulic rod 302 is extended or retracted. If the steering hydraulic rod 302 extends, it pushes one end of the fixed frame 303, causing the fixed frame 303 to rotate around the rotation connection point with the bottom of the hydraulic telescopic rod 304, thereby changing the direction of the traveling track 307. If the steering hydraulic rod 302 retracts, it pulls one end of the fixed frame 303, causing the fixed frame 303 to rotate, changing the direction of the traveling track 307, thus turning the paver. When encountering different road conditions or needing to adjust the paving height, the hydraulic telescopic rod 304 is extended or retracted. When the hydraulic telescopic rod 304 extends, it pushes the fixed frame 303 downward, reducing the contact height between the traveling track 307 and the ground, thus lowering the overall height of the paver. When the hydraulic telescopic rod 304 retracts, it pulls the fixed frame 303 upward, increasing the contact height between the traveling track 307 and the ground, thus raising the overall height of the paver.

[0026] Through the transmission method of the walking motor 305, drive disc, connecting belt 308 and walking roller 306, the power transmission process is stable and reliable, ensuring that the paver moves at a stable speed, which is conducive to ensuring the continuity and uniformity of paving operations. The design of the walking track 307 gives the paver good passability and can adapt to various complex road conditions, such as muddy, soft or uneven road surfaces, improving the applicability of the paver in different construction environments. The setting of the steering hydraulic rod 302 enables the paver to achieve flexible steering. In narrow spaces or when frequent adjustments to the construction direction are required, the paver can quickly and accurately change the direction of travel, reducing the time spent on stopping and adjusting during construction and improving construction efficiency.

[0027] In this embodiment, a hopper 2 is fixedly connected to the top of the frame 1, a rotating auger 6 is provided at the bottom of the hopper 2, a paving plate 9 is provided on one side of the inner cavity of the frame 1, the paving plate 9 is in the shape of an I-beam, a diversion plate is provided at the bottom of the hopper 2, the rotating auger 6 is located directly below the diversion plate, baffles 101 are provided on both sides of the rotating auger 6 on the frame 1, a drive motor 4 is fixedly connected to one side of the inner cavity of the frame 1, a drive gear is provided on the output shaft of the drive motor 4, a driven gear is provided at one end of the rotating auger 6, the drive gear and the driven gear are connected by a transmission belt 5, a hydraulic lifting rod 7 is fixedly connected to both sides of the inner cavity of the frame 1, the telescopic end of the hydraulic lifting rod 7 is fixedly connected to the top of the paving plate 9, a vibration motor 8 is provided on the top of the paving plate 9, and the paving plate 9 is located on one side of the rotating auger 6;

[0028] The asphalt concrete to be paved is poured into the hopper 2. Under the action of gravity, the asphalt concrete slides down the guide plate at the bottom of the hopper 2. The guide plate evenly guides the asphalt concrete onto the rotating auger 6 located directly below it. At this time, the drive motor 4 is started, and the output shaft of the drive motor 4 begins to rotate, driving the drive gear to rotate. Since the drive gear and the driven gear at one end of the rotating auger 6 are connected by a transmission belt 5, the rotation of the drive gear will drive the driven gear to rotate through the transmission belt 5, thereby causing the rotating auger 6 to start rotating. During the rotation of the rotating auger 6, the rotating auger 6 evenly conveys the asphalt concrete from the bottom of the hopper 2 towards the paving slab 9. The baffles 101 on both sides of the rotating auger 6 on the frame 1 act as obstructions to prevent asphalt from spreading. During the conveying process, the asphalt concrete overflows from both sides. The asphalt concrete conveyed by the rotating auger 6 reaches the front of the paving slab 9. The vibration motor 8 on the top of the paving slab 9 is started. The vibration motor 8 generates vibration and transmits the vibration to the paving slab 9. According to the actual construction requirements for paving thickness, the hydraulic lifting rods 7 on both sides of the inner cavity of the frame 1 are controlled to extend and retract. The extension and retraction ends of the hydraulic lifting rods 7 drive the paving slab 9 to move up and down, adjusting the distance between the paving slab 9 and the ground to achieve a suitable paving height. The paver moves forward under the drive of the traveling component 3. The paving slab 9 scrapes the asphalt concrete conveyed by the rotating auger 6 and, under the vibration of the vibration motor 8, initially compacts the asphalt concrete to form a flat and dense paving layer.

[0029] The diversion plate at the bottom of the hopper 2 guides the asphalt concrete to flow evenly to the rotary auger 6, avoiding the problem of asphalt concrete accumulating or unevenly distributed in the hopper 2. This ensures that the rotary auger 6 can evenly transport the asphalt concrete, providing a uniform material supply for subsequent paving operations and improving the smoothness of the paved layer. The baffles 101 on both sides of the frame 1 and the rotary auger 6 effectively prevent asphalt concrete from overflowing from both sides during transportation, reducing material waste and construction costs. It also prevents overflowing asphalt concrete from damaging other parts of the paver or affecting the construction environment. The drive motor 4 drives the rotary auger 6 to rotate through the drive gear, transmission belt 5, and driven gear. This transmission method has a simple structure and smooth transmission, ensuring that the rotary auger 6 transports asphalt concrete at a stable speed, improving the reliability and stability of transportation. The I-beam paving slab 9 has good structural strength and paving performance, and can better withstand the impact and pressure of asphalt concrete during paving, and is not easily deformed. At the same time, the vibration generated by the vibratory motor 8 can make the asphalt concrete more compact, reduce the voids inside the paving layer, and improve the quality and rutting resistance of the paving layer.

[0030] The working principle and usage process of this utility model are as follows: First, when the paver needs to move forward or backward, the travel motor 305 is started. The output shaft of the travel motor 305 begins to rotate, driving the drive disc to rotate. Since the drive disc is connected to one end of a travel roller 306 via a connecting belt 308, the rotation of the drive disc transmits power to the travel roller 306 through the connecting belt 308, causing it to start rotating. After the travel roller 306 rotates, it drives the travel track 307 to move. The travel track 307 also cooperates with the other travel roller 306, driving the other travel roller 306 to rotate through friction, thereby realizing the movement of the entire paver. When the paver needs to turn, the steering hydraulic rod 302 is controlled to extend or retract. If the steering hydraulic rod 302... When the hydraulic rod extends, it pushes one end of the fixed frame 303, causing the fixed frame 303 to rotate around the rotational connection point with the bottom end of the hydraulic telescopic rod 304, thereby changing the direction of the traveling track 307. When the hydraulic rod 302 retracts, it pulls one end of the fixed frame 303, causing the fixed frame 303 to rotate and changing the direction of the traveling track 307, thus turning the paver. When encountering different road conditions or needing to adjust the paving height, the hydraulic telescopic rod 304 is controlled to extend or retract. When the hydraulic telescopic rod 304 extends, it pushes the fixed frame 303 downward, reducing the contact height between the traveling track 307 and the ground, thus lowering the overall height of the paver. When the hydraulic telescopic rod 304 retracts, it pulls the fixed frame 303 upward, increasing the contact height between the traveling track 307 and the ground. As the temperature rises, the overall height of the paver increases, and the asphalt concrete to be paved is poured into the hopper 2. Under the action of gravity, the asphalt concrete slides down the guide plate at the bottom of the hopper 2. The guide plate evenly guides the asphalt concrete onto the rotating auger 6 located directly below it. At this time, the drive motor 4 is started, and the output shaft of the drive motor 4 begins to rotate, driving the drive gear to rotate. Since the drive gear and the driven gear at one end of the rotating auger 6 are connected by a transmission belt 5, the rotation of the drive gear will drive the driven gear to rotate through the transmission belt 5, thereby causing the rotating auger 6 to start rotating. During the rotation of the rotating auger 6, the rotating auger 6 evenly conveys the asphalt concrete from the bottom of the hopper 2 towards the paving slab 9. The baffles 101 on both sides of the rotating auger 6 on the frame 1 act as a barrier. The rotating auger 6 acts as a barrier to prevent asphalt concrete from overflowing from both sides during transportation. The asphalt concrete, transported by the rotating auger 6, reaches the front of the paving slab 9. The vibrating motor 8 on the top of the paving slab 9 is activated, generating vibration and transmitting it to the paving slab 9. Based on the actual paving thickness required for construction, the hydraulic lifting rods 7 on both sides of the inner cavity of the frame 1 are controlled to extend and retract. The extension and retraction ends of the hydraulic lifting rods 7 drive the paving slab 9 to move up and down, adjusting the distance between the paving slab 9 and the ground to achieve a suitable paving height. Driven by the traveling component 3, the paver moves forward. The paving slab 9 scrapes the asphalt concrete transported by the rotating auger 6 and, under the vibration of the vibrating motor 8, initially compacts the asphalt concrete, forming a flat and dense paving layer.
