[0017] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0018] A novel paver crawler scraper device according to an embodiment of the present utility model, as Figure 1 shown, includes: a scraper mounting seat 10, a swing arm 30, a scraper 40, and a limiting mechanism 50. The scraper mounting seat 10 is mounted on the crawler bracket 20; a preset position in the middle of the swing arm 30 is hinged to the scraper mounting seat 10 by bolts so that the front end of the swing arm 30 can swing up and down; the scraper 40 is mounted on the front end of the swing arm 30 to move up and down with the swing arm 30; the limiting mechanism 50 is arranged on the scraper mounting seat 10; wherein, the rear end of the swing arm 30 is a free end and corresponds to the limiting mechanism 50. The limiting mechanism 50 is used to clamp and limit the rear end of the swing arm 30 to adjust the relative height between the scraper 40 and the ground. The scraper mounting seat 10 is fixed on the crawler bracket 20, providing a stable mounting foundation for the swing arm 30, ensuring the stability and reliability of the entire device. The design of the limiting mechanism 50 enables the operator to conveniently adjust the height of the scraper 40, reduces the complexity of manual adjustment, improves work efficiency, and realizes the high efficiency, accuracy, and adaptability of the paving operation.

[0019] Furthermore, as Figure 1 shown, the limiting mechanism 50 includes: a support arm 51, a indexing pin locking hole 511, and an indexing pin 52. The support arm 51 is arranged on the scraper mounting seat 10. A plurality of indexing pin locking holes 511 are formed in the support arm 51, and the plurality of indexing pin locking holes 511 are evenly spaced along the vertical direction of the support arm 51; the indexing pin 52 is movably inserted through the rear end of the swing arm 30; wherein, the indexing pin 52 is used to insert into one of the indexing pin locking holes 511 to lock the position of the swing arm 30. The combination of the plurality of indexing pin locking holes 511 and the indexing pin 52 that can movably penetrate the rear end of the swing arm enables multiple choices for height adjustment, meets the requirements of different construction conditions and road surface conditions, and thus adapts to various complex construction terrains and working conditions.

[0020] Furthermore, as Figure 2 shown, the limiting mechanism 50 further includes: an upper limit block 53 and a lower limit post 54. The upper limit block 53 is arranged at the top of the support arm 51 and fixedly connected to the scraper mounting seat 10; the lower limit post 54 is arranged at the bottom of the support arm 51 and fixedly connected to the scraper mounting seat 10; wherein, the upper limit block 53 and the lower limit post 54 are used to limit the maximum swing range of the swing arm 30. The arrangement of the upper limit block 53 and the lower limit post 54 effectively limits the maximum swing range of the swing arm, ensures the stability and safety of the equipment operation, and prevents the scraper 40 from being damaged or affecting the normal operation of the paver due to excessive swing of the swing arm 30.

[0021] Further, as Figure 2 shown, a hexagonal nut is provided on the upper limit block 53. The hexagonal nut is used to adjust the gap between the scraper 40 and the road surface, further improving the construction accuracy and adaptability. It can accurately adjust the fitting degree between the scraper and the road surface according to different pavement materials and paving thicknesses, effectively preventing the accumulation and uneven distribution of asphalt materials, and ensuring the improvement of road surface flatness and construction quality.

[0022] Further, as Figure 1 shown, there are two scraper mounting seats 10, swing arms 30, and limit mechanisms 50. The two scraper mounting seats 10 are oppositely arranged on both sides of the crawler support 20. The middle preset positions of the two swing arms 30 are hinged to the two scraper mounting seats 10 through bolts; the front ends of the two swing arms 30 are fixedly connected to the scraper 40 correspondingly; the rear ends of the two swing arms 30 correspond to the two limit mechanisms 50. By setting two opposite scraper mounting seats 10, swing arms 30, and limit mechanisms 50, synchronous adjustment on both sides is achieved, ensuring the balance and stability of the paver during operation, avoiding uneven force and construction deviation that may be caused by single-side adjustment, enabling the paver to move forward more smoothly, and improving construction efficiency and quality.

[0023] Further, as Figure 1 shown, the scraper 40 has a "V"-shaped plate structure with a horizontal bend, and the included angle at the bend of the scraper 40 is greater than 90°. Through the scraping action of the scraper 40, the asphalt material can be more effectively scraped away, preventing it from sticking inside the crawler sprocket and affecting the normal operation of the equipment, reducing wear and damage to the equipment, thus extending the service life of the equipment and optimizing the entire material handling process.

[0024] This new type of paver crawler scraper device installs the scraper mounting seat 10 on the crawler support 20, and hinges the swing arm 30 so that its front end can swing up and down, driving the scraper 40 to adapt to the road surface height change. Then, the height of the scraper 40 is adjusted through the limit mechanism 50, and the swing range of the swing arm 30 is restricted. During the transfer or towing period, the scraper 40 is in the lifted state. During construction, the scraper 40 can be lifted or lowered to ensure the uniform and flat paving of the road surface.

[0025] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
