[0002] A paver is a construction equipment mainly used in projects such as highways, urban roads, and airport runways to pave asphalt concrete base and surface materials.

[0003] For example, the Chinese authorized patent (Asphalt Concrete Paver) with announcement number CN219604105U includes a first connecting frame and a second connecting frame that are spliced ​​and fixed together. A connecting ear is fixedly welded to the side of the second connecting frame away from the first connecting frame. The first and second connecting frames are connected to external vehicles through the connecting ear, allowing the external vehicles to tow the first and second connecting frames. A rotating drum is rotatably installed inside the first connecting frame via a rotating shaft, and a paving component is provided on the bottom surface of the first connecting frame. In this invention, during rotation, the rotating drum drives multiple sets of movable paving claws to continuously move away from and towards each other around the midpoint of the fixed rod. These movable paving claws spread the asphalt concrete on the road surface, making the piled asphalt concrete evenly spread, thus improving the uniformity of asphalt concrete paving.

[0004] However, the installation and removal of the gravity roller of existing asphalt concrete pavers require disassembling the connection structure between the gravity roller and the mounting frame. This involves disassembling both the fixed structure and the rotating connection structure, which is complex and involves many steps. Frequent disassembly can also lead to loosening of the rotating and fixed parts, resulting in poor stability and inconvenience in installation and removal. Therefore, it does not meet the existing requirements. To address this, we have proposed an asphalt concrete paver device. Utility Model Content

[0005] The purpose of this utility model is to provide an asphalt concrete paver device to solve the problem mentioned in the background art that when installing and disassembling the gravity roller of the existing asphalt concrete paver, it is necessary to disassemble the connection structure between the gravity roller and the mounting frame. This requires disassembling the fixed structure and the rotating connection structure, which is complicated and involves many steps. Frequent disassembly can also easily lead to loosening of the rotation and the fixed structure, resulting in poor stability and inconvenience in installation and disassembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an asphalt concrete paver device, comprising: a mounting frame, wherein a first paving mechanism is disposed inside the mounting frame, and a second paving mechanism is disposed on one side of the first paving mechanism; both the first and second paving mechanisms include a gravity roller, and connecting seats are disposed on both ends of the gravity roller; a connecting component is disposed on one side of the connecting seat; both the first and second paving mechanisms further include a rotating component, and the rotating component is located on one side of the connecting component.

[0008] Preferably, the connecting assembly further includes a movable base, which is welded to the other side surface of the connecting sleeve.

[0009] Preferably, the rotating assembly includes a rotating seat, one side surface of which is provided with a moving groove, and the rotating seat moves along the moving groove.

[0010] Preferably, the front surfaces of both the movable seat and the rotating seat are provided with fixing holes, and the fixing holes penetrate through the movable seat and the rotating seat.

[0012] Preferably, the upper surface of each corner of the mounting bracket is provided with mounting brackets, and the mounting brackets are welded and fixed to the mounting bracket.

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

[0014] (1) This utility model achieves the rotation of the gravity roller and the mounting frame by connecting the connecting seat, connecting component and rotating component. The gravity roller is placed between two connecting sleeves, and then the connecting sleeve is moved so that the connecting seat is inserted into the connecting groove and the stabilizing protrusion is inserted into the stabilizing groove. The moving seat and the rotating seat are fixed by fasteners. When the rotating seat rotates, it will drive the gravity roller to rotate. When the gravity roller needs to be disassembled for replacement, only the fasteners need to be removed, and then the moving seat moves along the moving groove. The connecting seat and the connecting sleeve are separated, so the gravity roller can be disassembled without disassembling the rotating component. The disassembly structure is reduced, and the firmness and stability of the connection between the rotating component and the mounting frame will not be affected by multiple disassemblies. This improves the convenience of disassembly and the safety during use. It solves the problem that when installing and disassembling the gravity roller of the existing asphalt concrete paver, the connection structure between the gravity roller and the mounting frame needs to be disassembled. This requires disassembling the fixed structure and the rotating connection structure. The disassembly is complicated and involves many steps. Frequent disassembly can easily lead to loosening of the rotation and the fixed structure, resulting in poor stability and inconvenience of installation and disassembly.

[0015] (2) By setting a stabilizing groove on the outer wall of the connecting seat and a stabilizing protrusion on the inner wall of the connecting groove, when the connecting seat is inserted into the connecting groove, the stabilizing protrusion is inserted into the stabilizing groove, which has a limiting effect and improves the stability of the rotation of the connecting sleeve and the connecting seat.

The inner wall is provided with a stabilizing protrusion 14, and the connecting seat 10 is inserted into the connecting groove 13, and the stabilizing protrusion 14 is inserted into the stabilizing groove 11. The connecting assembly 8 also includes a movable seat 15, and the movable seat 15 is welded to the other side surface of the connecting sleeve 12. The rotating assembly 9 includes a rotating seat 16, and a movable groove 18 is provided on one side surface of the rotating seat 16. The movable seat 15 moves along the movable groove 18. When the movable seat 15 moves along the movable groove 18 to the bottom, the gravity roller 7 is placed between the two connecting sleeves 12. Then the connecting sleeve 12 is moved so that the connecting seat 10 is inserted into the connecting groove 13, and the stabilizing protrusion 14 is inserted into the stabilizing groove 11, so that the connecting sleeve 12 and the connecting seat 10 are connected.

[0023] pass Figure 3 and Figure 4 It is understood that the front surfaces of both the movable seat 15 and the rotating seat 16 are provided with fixing holes 20, and the fixing holes 20 penetrate through the movable seat 15 and the rotating seat 16. One end of the fixing hole 20 is provided with a fastener 19, and one end of the fastener 19 passes through the fixing hole 20 and is threaded to a nut. After the connecting sleeve 12 is connected to the connecting seat 10, the movable seat 15 and the rotating seat 16 are fixed by the fastener 19. In this way, when the rotating seat 16 rotates, it will drive the gravity roller 7 to rotate. When rotating, the stabilizing protrusion 14 is inserted into the stabilizing groove 11, which plays a limiting role and improves the stability of the rotation of the connecting sleeve 12 and the connecting seat 10.

The connecting seat 10 separates from the connecting sleeve 12, thus enabling the gravity roller 7 to be disassembled without disassembling the rotating component 9. This reduces the number of disassembly structures and prevents the connection between the rotating component 9 and the mounting frame 1 from being compromised due to multiple disassemblies, thereby improving the convenience of disassembly and the safety during use.

[0025] Please see Figure 1 , 4 The rotating assembly 9 also includes a rotating shaft 17.
