Description

Technical Field

[0001] This utility model relates to the technical field of concrete pavement construction, and in particular to an asphalt concrete pavement laying device. Background Technology

[0002] Asphalt concrete pavement refers to various types of pavement constructed by incorporating road asphalt materials into concrete. The asphalt binder improves the ability of the paving aggregate to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt concrete pavement is one of the most widely used pavement types in road construction.

[0003] During asphalt paving, the asphalt concrete is concentrated on the conveyor belt and is not easy to disperse evenly, which makes the subsequent scraping and shaping operation difficult. In addition, the scraper lacks adjustability and cannot properly pave different types of roads as needed. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing an asphalt concrete pavement laying device.

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

[0006] An asphalt concrete pavement laying device includes a paver, a conveyor belt mounted on the paver via a bracket, a drive motor connected to the shaft of the conveyor belt, several n-shaped frames on the paver, a paving component mounted on the lower end of the cross plate of the n-shaped frame, the paving component being located on the upper surface of the conveyor belt, a material guide chute located below the conveyor belt in the conveying direction on the rear side of the paver, fixed cross plates on the front and rear sides of the rear end of the paver, a scraper fixing seat installed between two fixed cross plates, a scraper mounted on the bottom of the scraper fixing seat, a road shaping groove provided on the bottom of the scraper, and connecting ear plates provided on the mating surfaces of the scraper fixing seat and the scraper, the connecting ear plates being detachably installed and fixed by a first bolt.

[0007] The slab assembly includes two slab blocks. The outer side of each slab block has an inclined surface facing the front end of the drive belt. The inclined surfaces of the two slab blocks form a figure-eight structure. The spacing between the two slab blocks on the n-shaped frame gradually increases from front to back.

[0008] The bottom of the paver is equipped with a "┛"-shaped front sweeper plate near the material guide chute.

[0009] The top of the feed chute is equipped with an inverted V-shaped feed inlet.

[0010] The beneficial effects of this utility model are: the asphalt concrete paving component can spread the asphalt concrete material as much as possible, which is beneficial to subsequent shaping operations; the scraper is detachable and can be replaced as needed, which is beneficial to the paving of different types of roads.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0020] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] An asphalt concrete pavement laying device, such as Figures 1 to 2 As shown, it includes a paver 1, a support frame 2, a conveyor belt 3, a drive motor 4, an n-shaped frame 5, a paving assembly 6, a guide chute 7, a fixed cross plate 8, a scraper fixing seat 9, a scraper 10, a connecting ear plate 11, a first bolt 12, a "┛" shaped front sweeper 13, a second bolt 14, and a third bolt 15.

[0024] The paver 1 includes a frame 101, with wheels 102 at the bottom of the frame 101 and a cab 103 at the front end of the frame 101.

[0025] A conveyor belt 3 is mounted on the paver 1 via a bracket 2. The shaft of the conveyor belt 3 is connected to a drive motor 4. The paver 1 is equipped with several n-shaped frames 5. A paving assembly 6 is installed at the lower end of the cross plate of the n-shaped frame 5. The paving assembly 6 is located on the upper surface of the conveyor belt 3. The paving assembly 6 includes two paving blocks 601. The outer side of the paving block 601 facing the front end of the conveyor belt 3 has an inclined surface 602. The inclined surfaces 602 of the two paving blocks 601 form a figure-eight structure. The spacing between the two paving blocks 601 on the n-shaped frame 5 gradually increases from front to back.

[0026] A material guide chute 7 is provided on the rear side of the paver 1 below the conveyor belt 3 in the conveying direction. The top of the material guide chute 7 is provided with an inverted V-shaped inlet, which makes it more convenient to feed and guide materials.

[0027] The paver 1 has fixed cross plates 8 on both the front and rear sides at the rear end. The fixed cross plates 8 are fixed to the front and rear side walls of the paver 1 by the second bolts 14.

[0028] A scraper fixing seat 9 is installed between the two fixed horizontal plates 8, and the scraper fixing seat 9 is fixed to the fixed horizontal plate 8 by a third bolt 15.

[0029] The scraper mounting base 9 has a scraper 10 installed at the bottom. The scraper 10 has a road shaping groove at the bottom. Both the scraper mounting base 9 and the scraper 10 have connecting ear plates 11 on their mating surfaces. The connecting ear plates 11 can be detached and fixed by the first bolt 12, which makes it easy to replace the appropriate scraper 10.

[0030] Sometimes the height and width of the road surface that need to be corrected are inconsistent, so it is necessary to replace it with something like... Figure 3 The scraper 10 shown can be replaced if sidewalls are directly generated on both sides of the road surface. Figure 4 The scraper 10 shown.

[0031] The bottom of the paver 1 is equipped with a “┛”-shaped front sweeper 13 near the material guide chute 7, which can first scrape away debris on the road surface, which is beneficial to the paving of the road surface.

[0032] This utility model is used in conjunction with an asphalt concrete mixing and conveying tank during operation. As the paver 1 moves, the asphalt concrete mixing and conveying tank continuously drips asphalt concrete onto the surface of the conveyor belt 3. Due to the concentrated dripping of asphalt concrete, the asphalt concrete can be spread out using the spreading blocks 601 of the continuously expanding spreading component 6, making its distribution more uniform and facilitating subsequent road surface shaping. The asphalt concrete is guided to the ground through the guide chute 7 and finally shaped by the road surface shaping groove on the scraper 10. The scraper 10 can be replaced as needed, providing higher adaptability.

[0033] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
