[0002] During asphalt pavement construction, there are situations where pavers cannot be used for edge or local repairs. The traditional method is to use auxiliary tools such as trowels and shovels to level the surface. This method is labor-intensive for operators, and while shovels can be used for digging and leveling, the paving quality cannot be guaranteed.

[0003] Existing technologies also use toothed rakes for paving, but because the rake teeth are sparse, repeated operation is required, resulting in low paving efficiency. Moreover, cleaning up debris stuck to the rake teeth is time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide an asphalt pavement leveling device that has good paving quality, high efficiency and easy cleaning.

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

[0006] The asphalt pavement leveling device disclosed in this utility model includes:

[0007] A paving head for leveling road surfaces and having an arc-shaped, sheet-like structure; a support frame mounted on top of the paving head, wherein a sleeve of the support frame is fixedly connected to a handle; and

[0008] A connecting component extends through the paving head and the support, enabling the paving head and the support to be detachably and fixedly connected. A shielding member extending along the length of the paving head is fixedly connected to the inner wall of the paving head, covering the end of the connecting component.

[0009] Furthermore, the shielding component is a straight or arc-shaped baffle, and the two sides of the baffle are fixedly connected to the inner wall of the paving head so that a cavity is formed between the shielding component and the paving head.

[0010] Furthermore, end plates are welded between the two sides of the shielding member and the paving head, thereby sealing the cavity.

[0011] Furthermore, the connecting assembly includes a rivet nut and a connecting rod connected to the rivet nut.

[0012] Furthermore, the bracket includes a base plate, on which the sleeve is welded, and the base plate has a plurality of first mounting holes for installing the connecting components. First diagonal braces are obliquely connected between the sleeve and the base plate on both sides.

[0013] Furthermore, the bracket also includes a second diagonal brace disposed on the front side of the grip bar, and an upwardly extending wing plate is disposed in the center of the base plate, with the second diagonal brace welded between the wing plate and the sleeve.

[0014] Furthermore, the bracket also includes connecting ribs, the two ends of which are fixedly connected to the first diagonal tie ribs, and the middle part is fixedly connected to the sleeve.

[0015] Furthermore, a third mounting hole, coaxial with the first mounting hole, is provided at the connection position between the sleeve and the base plate for installing the connecting assembly.

[0016] Furthermore, the paving head has a second mounting hole corresponding to the first mounting hole position for installing the connecting component.

[0017] Furthermore, the sleeve forms an inclined angle with the horizontal plane.

[0018] In the above technical solution, the asphalt pavement leveling device provided by this utility model firstly has two sides of the paving head as cutting edges, which can scrape and trim the asphalt aggregate with little effort, keeping the pavement and edges flat and regular. It can also scrape off the asphalt mixture adhering to the side of the curbstone. At the same time, when cutting excess asphalt, it can reduce the accumulation of aggregate, ensure uniform paving thickness and flatness, not only reducing the labor intensity of construction workers, but also improving work efficiency.

[0019] Secondly, the shielding parts cover the protruding parts of the internal connecting components of the paving head, effectively ensuring that the working surface of the paving head is flat and easy to clean;

[0020] In addition, the paving head and the support can be detached and connected via a connecting component. If the cutting edges on both sides of the paving head are chipped, deformed, or worn, they can be replaced at any time. Other parts can be reused, saving costs. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] See Figure 1-3 As shown;

[0035] The utility model discloses an asphalt pavement leveling device, comprising: a paving head 1, a support 2, and a handle 3. The paving head 1 is made of stainless steel, the support 2 is made of carbon steel, and the handle 3 is a round bar made of wood or plastic. One end of the handle 3 is interference-fitted with the sleeve 22 of the support 2 and riveted with iron nails.

[0036] The paving head 1 has a structure of less than or equal to half an arc-shaped sheet, which is used to push, pull, and shovel to level the road surface. The support 2 and the paving head 1 can be detached and connected by a connecting component, which makes it easy to replace the paving head 1 with a new one when it is worn out during use.

[0037] The connecting assembly includes a connecting rod 7 and a rivet nut 6. The connecting rod 7 is a bolt or a rod with external threads for easy disassembly. The bracket 2 has a first mounting hole 212, and the paving head 1 has a second mounting hole corresponding to the first mounting hole 212. The rivet nut 6 is riveted into the second mounting hole (e.g., Figure 5As shown), during assembly, the connecting rod 7 passes through the first mounting hole 212 and is connected to the rivet nut 6. The inner wall of the paving head 1 is fixedly connected to a shielding member 4 extending along its length. The shielding member 4 covers the rivet nut 6 to ensure that the working surface of the paving head 1 is flat and avoids protrusions, which would make it difficult to clean the impurities stuck to the protrusions. The shielding member 4 is fixedly connected to the inner wall of the paving head 1 on both sides by welding. The shielding member 4 is constructed as a straight or arc-shaped stainless steel baffle. The baffle forms a cavity with the paving head 1 to accommodate the rivet nut 6.

[0038] To prevent impurities from entering the cavity and increasing the weight of the paving head 1, end plates 5 are welded between the two sides of the baffle and the paving head 1, thereby sealing the cavity.

[0039] See Figure 1 , 4 As shown:

[0040] The support frame 2 includes a base plate 21, on which a sleeve 22 is welded. After the support frame 2 is assembled with the paving head 1, the sleeve 22 forms an inclined angle with the horizontal plane (see...). Figure 3 (as shown)

[0041] The base plate 21 has three first mounting holes 212, through which the connecting rod 7 is installed. The sleeve 22 is inclinedly connected to the base plate 21 on both sides. The first diagonal bracing 24 and the sleeve 22 form a triangular support structure on both sides of the sleeve 22 to ensure the structural strength between the base plate 21 and the sleeve 22.

[0042] See Figure 3 As shown, the bracket 2 also includes a second diagonal brace 25 disposed on the front side of the handle 3, and an upwardly extending wing plate 211 disposed in the center of the base plate 21 (as shown). Figure 6 As shown, a second diagonal brace 25 is welded between the wing plate 211 and the sleeve 22 to form a triangular support structure on the front side of the sleeve 22, further ensuring the structural strength between the bottom plate 21 and the sleeve 22. The first diagonal brace 24 and the second diagonal brace 25 effectively ensure the left-right and front-back stability of the sleeve 22.

[0043] See Figure 4 As shown, preferably, the support 2 also includes a connecting rib 26, with both ends of the connecting rib 26 fixedly connected to the first diagonal tie rib 24 and the middle part fixedly connected to the sleeve 22. In this structure, the connecting rib 26 is rooted in the sleeve 22 and horizontally pulls two first diagonal tie ribs 24, which can further improve the structural strength of the support.

[0044] Preferably, a third mounting hole 221 coaxial with the first mounting hole 212 is provided at the connection position between the sleeve 22 and the base plate 21. A connection point is set in the middle using the third mounting hole 221 to connect the paving head 1. During assembly, the connecting rod 7 passes through the third mounting hole 221 and the first mounting hole 212 in sequence and is connected to the rivet nut 6.

[0045] See Figure 5 As shown:

[0046] Preferably, the paving head 1 has a second mounting hole at the position corresponding to the first mounting hole 212 for installing the rivet nut 6, which is convenient for assembly and can control the protrusion height of the connecting component, making it easy to control the cavity size. The rivet nut 6 can be a blind hole rivet nut.

[0047] In the above technical solution, the asphalt pavement leveling device provided by this utility model has two sides of the paving head 1 as cutting edges, which can scrape and trim the asphalt aggregate with little effort, keeping the pavement and edges flat and regular. It can also scrape off the asphalt mixture adhering to the side of the curbstone. At the same time, when cutting excess asphalt, it can reduce the accumulation of aggregate and ensure uniform paving thickness. This not only reduces the labor intensity of construction workers, but also improves the work efficiency.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
