Description

Technical Field

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

[0002] Asphalt pavers are key pieces of equipment in road construction, primarily used to evenly spread asphalt mixtures on the road surface and form a smooth, dense road surface through processes such as compaction. Their working principle typically involves the coordinated operation of multiple systems. With the continuous improvement of road construction standards, higher requirements are being placed on the performance of asphalt pavers, such as higher paving efficiency, more precise paving control, and stronger environmental adaptability.

[0003] However, existing asphalt pavers still have some shortcomings. First, the paving width adjustment of some pavers is inconvenient, making it difficult to adapt to the construction needs of roads of different widths, thus affecting construction efficiency. Furthermore, the heating effect of the screed is poor, easily causing the asphalt mixture to stick to the screed, affecting the continuity and stability of paving. Secondly, the vibration mechanism of some pavers is inefficient, failing to adequately pre-compact the asphalt mixture, leading to increased subsequent compaction work and affecting the overall quality of the road surface, thereby reducing the practicality of the paver. Therefore, the applicant proposes a small asphalt paver to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a small asphalt paver to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Small asphalt pavers include:

[0007] The frame and wheels are mounted at the four corners of the lower end of the frame, and a hopper is fixedly installed at the upper end of the frame;

[0008] A control panel is fixedly installed on the rear side of the hopper, and a platform is fixedly installed on the lower end of the control panel by two support rods.

[0009] A scraper is provided on one side of the frame, and multiple paving rollers are provided on the side of the scraper away from the frame. A spiral material distribution mechanism is provided on the side of the multiple paving rollers away from the scraper.

[0010] Controllers are installed on both sides of the frame, and longitudinal slope sensors are installed on one side of each of the two controllers. Leveling devices are installed at the bottom of each of the two controllers. An ironing main board is installed on the rear side of the frame and below the control panel via a connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The frame and wheels ensure the paver travels smoothly under various working conditions, providing a reliable guarantee for continuous construction. The paving roller and the paver travel speed are precisely matched to ensure the uniformity and density of the paving layer. Through the coordinated action of the controller, longitudinal slope sensor and leveling instrument, the automatic leveling of the paving process is realized to ensure that the flatness and thickness of the road surface meet the requirements. The hydraulic cylinder and the screed make the paving width adjustable to adapt to the needs of different road surfaces.

[0026] Example 1:

[0027] Please see Figures 1-4 As shown, a small asphalt paver includes: a frame 1 and wheels 2 mounted at the four corners of the lower end of the frame 1; a hopper 3 is fixedly installed at the upper end of the frame 1.

[0028] A control panel 14 is fixedly installed on the rear side of the hopper 3, and a platform 13 is fixedly installed on the lower end of the control panel 14 through two support rods.

[0029] A scraper 6 is provided on one side of the frame 1, and multiple paving rollers 16 are provided on the side of the scraper 6 away from the frame 1. A spiral material distribution mechanism 4 is provided on the side of the multiple paving rollers 16 away from the scraper 6.

[0030] Controllers 15 are installed on both sides of the frame 1. Slope sensors 10 are installed on one side of each controller 15. Leveling devices 5 are installed at the bottom of each controller 15. An ironing main board 7 is installed on the rear side of the frame 1 and below the control panel 14 via a connecting rod.

[0031] As can be seen from the above, the paver achieves self-propelled movement by using the frame 1 and wheels 2, and by starting the power unit via the control panel 14 to move the wheels 2. Multiple wheels 2 ensure the paver's stability and maneuverability to adapt to different construction needs, providing a stable walking platform and ensuring stability and continuity during construction. The paving roller 16, a core component of the paver, rotates to evenly spread the asphalt mixture on the ground. The rotation speed of the paving roller 16 coordinates with the paver's travel speed to ensure the thickness and smoothness of the paved layer, guaranteeing uniformity and evenness of the paved surface. To improve the compactness and thus the smoothness and durability of the road surface, the longitudinal slope sensor 10 and the leveling device 5 are configured to detect changes in the longitudinal slope of the road surface in real time during the paving process. The longitudinal slope sensor 10 transmits the signal to the controller 15, which then controls the action of the leveling device 5 according to the signal. This adjusts the height and angle of the screed to keep the paving thickness consistent, achieving automatic leveling. This ensures that the smoothness and thickness of the paved road surface meet the requirements, improving the road quality. The paver, through control and regulation and the coordinated operation of multiple mechanisms, achieves efficient paving, improves road quality and construction efficiency, ensures a smooth and compact paving surface, and thus enhances the practicality of the paver.

[0032] For details, please refer to Figure 3 As shown, hydraulic cylinders 9 are fixedly installed on both sides of the ironing main board 7, and ironing auxiliary boards 8 are fixedly installed on both sides of the ironing main board 7 through the hydraulic cylinders 9.

[0033] As can be seen from the above, by setting up the hydraulic cylinder 9 and starting the hydraulic cylinder 9 through the control panel 14, the width of the two screeds can be adjusted by extending and retracting the hydraulic cylinder 9 to adapt to the paving requirements of different road widths, improve the adaptability of the equipment to different working conditions, and achieve rapid and accurate switching of paving width through adjustment to ensure paving smoothness.

[0034] For details, please refer to Figure 1 As shown, the spiral material distribution mechanism 4 includes spiral blades, which are connected by a drive device. A chain is provided on one side of the scraper 6 and at the bottom of the hopper 3.

[0035] As can be seen from the above, the chain driven by the control panel 14 drives the transverse scraper 6 to slide on the base plate. When the scraper 6 passes through the asphalt mixture accumulated on the base plate, it carries the material through the gate, forming a moving material flow with a certain flow rate. It continuously delivers the asphalt mixture to the spiral blades, ensuring that the asphalt mixture can be continuously and evenly delivered from the hopper 3 to the spiral distribution mechanism 4. This provides a stable material supply for subsequent paving operations and avoids affecting the paving quality and efficiency due to insufficient or intermittent material supply. When the asphalt mixture is delivered to the spiral distribution mechanism 4, the drive device drives the spiral blades to start rotating, distributing the mixture laterally across the entire paving width. This avoids local accumulation or lack of mixture, thereby improving the uniformity and smoothness of the paving.

[0036] For details, please refer to Figure 3 As shown, the heating mechanism 11 includes heating elements disposed within the ironing main plate 7 and the two ironing auxiliary plates 8.

[0037] As can be seen from the above, the heating element is activated by the control panel 14 to heat the screed. The heated screed can effectively prevent the asphalt mixture from sticking to the screed, ensuring the continuity and stability of the paving. In addition, heating helps to compact the asphalt mixture, improves the density and strength of the paved layer, and thus improves the performance of the road surface.

[0038] refer to Figure 3 As shown, the compaction mechanism 12 includes a vibration mechanism disposed within the ironing main plate 7 and two ironing auxiliary plates 8, and the vibration mechanism includes a vibration beam and a hydraulic motor.

[0039] As can be seen from the above, the asphalt mixture is pre-compacted by a vibrating mechanism. Driven by a hydraulic motor, the vibrating mechanism reciprocates and vibrates the mixture at high frequency, expelling air from the mixture. Through pre-compaction, the density of the paving layer is increased, reducing the workload of subsequent roller compaction. The compaction helps to make the paving layer surface smoother and improve the overall quality of the road surface. The dense paving layer has better stability and durability and can withstand greater traffic loads and the impact of the natural environment.

[0040] refer to Figure 1 As shown, the control panel 14 includes multiple operation buttons and a display screen located at the top of the control panel 14, and a steering wheel is located on one side of the display screen.

[0041] As can be seen from the above, by integrating various operation buttons, display screen and steering wheel through the control panel 14, the operator can adjust various parameters of the paver, such as paving speed, scraper 6 conveying speed, paving roller 16 vibration frequency, etc., so that the control panel 14 can achieve precise control and improve the accuracy and quality of paving. Among them, the power unit and drive unit and other equipment mentioned above are connected to the control panel 14 through external power supply, which is existing technology and will not be described in detail here.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
