Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1: See Figures 1 to 8 In this embodiment of the invention, an intelligent anti-clogging asphalt uniform paving device includes a support base 1, a paving box 2 at the upper end of the support base 1, a baffle 14 installed inside the paving box 2, a feeding hopper 12 connected to one side of the lower end of the baffle 14, a feeding mechanism inside the feeding hopper 12, a scraper 16 also installed inside the paving box 2 located above the baffle 14, an anti-clogging mechanism for controlling the movement of the scraper 16 also installed on the paving box 2, at least two groups of layered paving mechanisms are also installed inside the paving box 2 below the baffle 14, and a feeding hopper 13 is connected to the upper end of the paving box 2, with a cover plate 5 placed on the upper side of the feeding hopper 13.

[0022] To facilitate the stable movement of the entire paving equipment on the road surface, front wheels 7 are symmetrically installed on the lower front side of the paving box 2, and support frames 3 are symmetrically installed on the upper rear side of the support base 1. Rear wheels 4 are installed at the lower end of the support frames 3, and handrails 6 are installed at the upper ends of the support frames 3. This allows construction workers to achieve rapid movement simply by controlling the handrails 6.

[0023] The material feeding mechanism in this paving equipment includes a feeding auger 11 rotatably installed inside the feeding hopper 12. One end of the feeding auger is connected to the output end of a feeding motor 8, which is installed on the outer wall of the paving box 2. The feeding motor 8 controls the rotation of the feeding auger 11, thereby allowing the asphalt inside the feeding hopper 12 to be fed in an orderly manner without causing blockage.

[0024] The anti-clogging mechanism in this paving equipment includes a rotating frame 19 rotatably installed on the inner wall of the paving box 2. A scraper 16 is fixedly installed at the bottom of the rotating frame 19. An abutment frame 15 is hingedly installed at the upper end of the rotating frame 19 through the paving box 2. An operating frame 20 is hingedly installed at the end of the abutment frame 15 away from the rotating frame 19. The operating frame 20 is rotatably installed on the support frame 3 through a hinge shaft 17. An operating handle 18 is fixedly installed at the upper end of the operating frame 20.

[0025] With the above setup, during the asphalt paving process, the construction workers continuously move the operating handle 18 back and forth. Then, under the action of the operating frame 20, the rotating frame 19 drives the abutment frame 15 to move back and forth, which in turn causes the scraper 16 to scrape back and forth along the upper surface of the baffle 14, thereby orderly scraping the asphalt located above the baffle 14 into the hopper 12 to achieve the purpose of material discharge, avoiding blockage, and further ensuring the uniform paving of asphalt.

[0026] In one embodiment, the layered paving mechanism includes fixed plates 23 symmetrically fixed to the bottom of the baffle 14. Each fixed plate 23 has a guide post 27 symmetrically fixedly installed at its lower end. A positioning plate 28 is slidably installed at the bottom of the guide post 27. The upper end of the positioning plate 28 is installed at the lower end of the fixed plate 23 by a positioning spring 26. A connecting plate 24 is fixedly installed between the upper ends of the positioning plates 28. A paving roller 10 is rotatably installed between the positioning plates 28. The layered paving mechanism also includes a transmission assembly and a lifting assembly.

[0027] The lifting assembly includes a rotating shaft 21 rotatably mounted between fixed plates 23, a rotating cam 22 fixedly mounted on the rotating shaft 21, and the bottom of the rotating cam 22 in contact with and cooperates with an abutment block 25 fixed on a connecting plate 24.

[0028] In addition, a paving motor 9 is installed on the outside of the paving box 2, and the output end of the paving motor 9 is connected to the rotating shaft 21.

[0029] With the above settings, the paving motor 9 is started, which directly drives the rotating shaft 21 to rotate, thereby causing the rotating cam 22 to rotate. Then, under the interaction between the rotating cam 22 and the abutment block 25, the positioning plate 28 moves up and down under the limiting and guiding action of the guide column 27 and the positioning spring 26, thereby causing the paving roller 10 to continuously squeeze and flatten the newly laid asphalt.

[0030] Example 2: In another embodiment of the present invention, the difference between this embodiment and the above embodiment is that the transmission assembly includes an upper transmission frame 30 and a lower transmission frame 29. The upper transmission frame 30 is coaxially hinged to the end of the rotating shaft 21, and the lower transmission frame 29 is coaxially hinged to the paving roller 10. An intermediate shaft is also hinged between the upper transmission frame 30 and the lower transmission frame 29. An upper pulley group 31 is provided between the intermediate shaft and the rotating shaft 21, and a lower pulley group 32 is provided between the intermediate shaft and the paving roller 10.

[0031] With the above configuration, the torque on the rotating shaft 21 can be effectively transmitted to the paving roller 10 through the cooperation of the two pulley sets and the two transmission frames. It can also ensure that changes in the distance between the paving roller 10 and the rotating shaft 21 will not interfere with its operation, thus further ensuring the reliability of this paving equipment.

[0032] In summary, during the paving process, the dimensions of the rotating cams 22 in the lifting components of the two layered paving mechanisms are different. The size of the rotating cam 22 closer to the hopper 12 is significantly smaller than that of the other. This allows the vertical movement of the latter lifting component to be significantly greater than that of the former during the operation of the two layered paving mechanisms. This ensures that the asphalt is paved and extruded in layers during the extrusion process, dividing a certain extrusion distance into two segments for extrusion and paving, thus ensuring that the asphalt is evenly spread on the road surface. Furthermore, with the cooperation of the anti-clogging mechanism and the material feeding mechanism, this paving equipment can achieve anti-clogging material feeding and even paving of asphalt, further guaranteeing its paving quality and efficiency, making it worthy of widespread application.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
