[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a highly efficient automatic paving machine capable of laying multiple road surface specifications.

[0026] In one embodiment, a high-efficiency automatic paving machine capable of laying multiple road surface specifications includes a paver 100 and a discharge pipe 200 installed on its outer side; it also includes an adjustment mechanism 300, which is installed on the paver 100 and used to control the paving width and thickness of concrete; wherein, the adjustment mechanism 300 includes two scrapers 310, which are arranged in a V-shape, and the adjacent ends of the two scrapers 310 are connected by a hinge, the scrapers 310 can move vertically, and a rubber strip 311 is provided at the connection of the two scrapers 310.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, an arc-shaped guide plate 312 is provided on the outer side of the scraper 310, and a scraper strip 313 is provided on the arc-shaped guide plate 312.

[0028] In this embodiment, the user pre-adjusts the angle between the two scrapers 310 and fine-tunes the paving range to quickly adapt to different paving needs, thereby improving construction efficiency and making it more efficient. With the rubber strip 311, the amount of concrete entering between the two scrapers 310 can be reduced without affecting the adjustment of the two scrapers 310. Then, the vertical height of the scrapers 310 is changed to adjust the paving thickness. Next, the concrete material in the paver 100 is discharged through the discharge pipe 200. Then, the scrapers 310 are used to guide and level the material. The concrete will move along the V-shape to both sides to complete the paving operation. During the paving process, the concrete flowing into the outside of the scrapers 310 will be guided by the arc guide plate 312 to the unpaved area to reduce the accumulation of material residue. After the paving operation is completed, the scraper strip 313 is used to scrape off the concrete residue on the scrapers 310 and the arc guide plate 312 to facilitate the subsequent use of the scrapers 310 and ensure the material guiding effect.

[0029] It should be noted that the paver 100 is model YZ25-4. Through the above-mentioned adjustment of paving range and paving thickness, it can meet the paving needs of different ground surfaces, realize the paving of multiple specifications of road surfaces, and the adjustment of paving range and thickness is flexible, effectively reducing the user's workload and improving paving efficiency.

[0030] The length of the scraper 310 can be adjusted according to actual paving requirements;

[0031] The discharge pipe 200 is equipped with a solenoid valve, which can adjust the amount of concrete discharged according to the adjustment of the laying range.

[0032] like Figure 2 and Figure 4 As shown, a support plate 314 is provided between the two scrapers 310, and a first electric push rod 315 is provided between the support plate 314 and the paver 100.

[0033] Activating the first electric push rod 315 can drive the support plate 314 and scraper 310 to move vertically, thereby changing the thickness of the concrete paving.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the support plate 314 has two second electric push rods 316 internally connected, and one end of the second electric push rod 316 is hinged to the outer side of the scraper 310.

[0035] The second electric push rod 316 is used to drive the corresponding scraper 310 to move, thereby adjusting the angle between the two scrapers 310 and changing the concrete paving range.

[0036] like Figure 3As shown, a folding rod 317 is rotatably connected to the outer side of the scraper 313, and a horizontal bar 318 is provided on the outer side of the scraper 310. One end of the folding rod 317 is slidably connected to the inside of the horizontal bar 318.

[0037] When the horizontal bar 318 moves, the folding rod 317 is driven by force, and one end of the folding rod 317 is rotatably connected to the scraper 313, so it can perform adaptive motion during the force process, reducing the occurrence of jamming while completing the drive of the scraper 313;

[0038] It should be noted that the end of the folding rod 317 is provided with a T-shaped slider, and the folding rod 317 is connected to the crossbar 318 through the T-shaped slider.

[0039] like Figure 3 As shown, a third electric push rod 319 is provided on the outer side of the folding rod 317, and one end of the third electric push rod 319 is connected to the crossbar 318.

[0040] Activating the third electric push rod 319 will cause the horizontal bar 318 to drive the folding rod 317 to move, thus completing the drive of the scraper 313.

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, the scraper 313 is bent, with one end of the scraper 313 movably connected to the interior of the arc-shaped guide plate 312, and the other end of the scraper 313 in contact with the outer surface of the arc-shaped guide plate 312.

[0042] The concrete scraping operation is carried out using the length of the scraper 313. The short end of the scraper 313 is connected to the folding rod 317 to facilitate the drive.

[0043] like Figure 3 As shown, both the scraper 310 and the arc-shaped guide plate 312 have movable grooves inside, and two adjacent movable grooves are connected.

[0044] The design of the movable groove provides movement space for the scraper 313, making it easier to complete the scraping operation.

[0045] Working principle: The first electric push rod 315 and the second electric push rod 316 are activated to adjust the vertical height and angle of the two scrapers 310, thereby adjusting the paving thickness and paving range. Then, the paver 100 is started to operate. During the movement, the material is discharged along the discharge pipe 200. Subsequently, the scrapers 310 are used to guide the material evenly for paving operations. At the same time, the paving range and thickness are controlled to meet the paving requirements of various road specifications. During the paving process, the arc-shaped guide plate 312 is used to guide the excess concrete on the scrapers 310 to reduce the accumulation of residue. After the paving operation is completed, the paver 100 is stopped. Then, the third electric push rod 319 drives the crossbar 318 and the folding rod 317 to move, causing the scraper 313 to follow the movement and scrape off the concrete remaining on the outside of the scrapers 310 and the arc-shaped guide plate 312. Then, the third electric push rod 319 drives the scraper 313 to return to its original position.

[0046] It should be noted that the first electric actuator 315, the second electric actuator 316, and the third electric actuator 319 can be used in small-scale paving operations. For large-scale paving operations, the corresponding cylinders (pneumatic or hydraulic) can be replaced. The specific usage and replacement depend on the actual needs. The first electric actuator 315, the second electric actuator 316, and the third electric actuator 319 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. The first electric actuator 315, the second electric actuator 316, and the third electric actuator 319 can be powered by an internal power supply or by AC power. The specific power supply method depends on the situation and will not be elaborated here.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
