Description

Technical Field

[0001] The utility model relates to the technical field of asphalt coating, in particular to an asphalt coating device for geogrids. Background Art

[0002] A glass fiber geogrid is a mesh structure material mainly made of glass fiber alkali-free and twist-free rovings, which is made by a certain weaving process. To protect the glass fiber and improve the overall performance, a new and excellent geotechnical base material is formed through a special coating treatment process. Therefore, a coating device is needed to complete the coating operation.

[0003] In the prior art, when asphalt coating is carried out on a geogrid, the situation of excessive coating may occur, resulting in an uneven surface of the geogrid, thus affecting the asphalt coating effect, and it cannot be adjusted according to the width of the geogrid during coating, resulting in poor practicability.

[0004] Therefore, this case proposes an asphalt coating device for geogrids to solve the above technical problems. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an asphalt coating device for geogrids, which can effectively solve the technical problems of uneven coating, affecting the coating effect, and inability to adjust according to the size of the geogrid in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An asphalt coating device for geogrids includes an asphalt placement box. A through hole is provided through the top end of the asphalt placement box. A first roller is rotatably connected to the inner wall of the asphalt placement box through a rotating shaft. On one side of the through hole corresponding to the top end of the asphalt placement box, a square scraping cylinder is fixedly penetrated. A notch is provided on one side of the top end of the square scraping cylinder. An upper scraping plate is fixedly connected to the inner wall of the square scraping cylinder. Two telescopic columns are slidably penetrated through both side surfaces of the square scraping cylinder. One end of each of the four telescopic columns away from the square scraping cylinder is fixedly connected to a fixed disk. One end of each of the four fixed disks close to the square scraping cylinder is fixedly connected to a tension spring outside the tension spring. All four tension springs are fixedly connected to the square scraping cylinder. One end of each of the four telescopic columns close to each other is fixedly connected to a side scraping plate.

[0008] As a further solution of the utility model, on the other side of the through hole corresponding to the top end of the asphalt placement box, fixing plates are symmetrically and fixedly connected. A second roller is rotatably connected between the two fixing plates through a rotating shaft.

[0009] As a further solution of the present utility model, a chute is provided at the top of the asphalt placement box corresponding to the lower side of the second rotating roller. One end of the chute is rotatably connected to a bidirectional threaded rod which penetrates through the asphalt placement box, and the other end of the bidirectional threaded rod is fixedly connected to a hand wheel.

[0010] As a further solution of the present utility model, both sides of the outer wall of the bidirectional threaded rod are threadedly connected with sliders. Both of the sliders are slidably connected to the chute, and the tops of both sliders are fixedly connected with limiting rings. Both of the limiting rings are arranged on the outer wall of the second rotating roller.

[0011] As a further solution of the present utility model, the chute is arranged between the fixing plates, and the limiting rings are used for limiting the geogrid.

[0012] As a further solution of the present utility model, the upper scraping plate scrapes off the excess asphalt on the top of the geogrid, the side scraping plate scrapes off the excess asphalt on both sides of the geogrid, and the notch scrapes off the excess asphalt at the bottom of the geogrid.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the mutual cooperation of the second rotating roller, the first rotating roller, the upper scraping plate, the notch, the tension spring, the telescopic column, the fixed disk and the side scraping plate, the excess asphalt coating can be scraped off, ensuring the uniformity of asphalt coating, avoiding excessive coating, preventing the surface of the geogrid from being uneven, thereby improving the coating effect. And the scraped asphalt falls into the lower asphalt placement box, so the asphalt coating can be recycled and resources can be saved;

[0015] Through the mutual cooperation of the hand wheel, the bidirectional threaded rod, the slider and the limiting ring, the limiting rings can contact both sides of the geogrid, thus playing a limiting role, preventing the geogrid from shifting during pulling, and thus being able to limit geogrids of different widths, improving the practicability.

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0021] As Figures 1-3 shown, a geogrid asphalt coating device includes an asphalt placement box 1. A through hole 2 penetrates through the top end of the asphalt placement box 1. The inner wall of the asphalt placement box 1 is rotationally connected with a first roller 3 through a rotating shaft. One side of the top end of the asphalt placement box 1 corresponding to the through hole 2 is fixedly penetrated with a square scraping cylinder 4. A notch 5 is opened on one side of the top end of the square scraping cylinder 4. The inner wall of the square scraping cylinder 4 is fixedly connected with an upper scraping plate 6. Two telescopic columns 7 penetrate through both side surfaces of the square scraping cylinder 4 in a sliding manner. One ends of the four telescopic columns 7 far away from the square scraping cylinder 4 are fixedly connected with fixed disks 9. One ends of the four fixed disks 9 close to the square scraping cylinder 4 are fixedly connected with tension springs 8 corresponding to the outer sides of the tension springs 8. The four tension springs 8 are all fixedly connected with the square scraping cylinder 4. One ends of the four telescopic columns 7 close to each other are fixedly connected with side scraping plates 10. Through the elastic action of the tension springs 8, the fixed disks 9 and the telescopic columns 7 are moved inwards, so that the side scraping plates 10 can contact geogrids with different widths. The upper scraping plate 6 scrapes off the excess asphalt on the top end of the geogrid, and the side scraping plates 10 scrape off the excess asphalt on both side ends of the geogrid. The notch 5 scrapes off the excess asphalt on the bottom end of the geogrid.

[0022] In this embodiment, two fixed plates 11 are symmetrically and fixedly connected to the other side of the top end of the asphalt placement box 1 corresponding to the through hole 2. A second roller 12 is rotationally connected between the two fixed plates 11 through a rotating shaft. Through the cooperation of the second roller 12 and the first roller 3, the geogrid can pass through the asphalt coating and complete the coating of the asphalt coating.

[0023] In this embodiment, a chute 13 is opened at the bottom of the top end of the asphalt placement box 1 corresponding to the second roller 12. One end of the chute 13 is rotationally connected with a bidirectional threaded rod 14 and penetrates through the asphalt placement box 1. The other end of the bidirectional threaded rod 14 is fixedly connected with a handwheel 17;

[0024] The chute 13 can limit the bidirectional threaded rod 14 to ensure the stable rotation of the bidirectional threaded rod 14.

[0025] In this embodiment, sliders 15 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 14. Both sliders 15 are slidably connected to the sliding grooves 13. Limit rings 16 are fixedly connected to the tops of both sliders 15. Both limit rings 16 are arranged on the outer wall of the second roller 12. The sliding grooves 13 are arranged between the fixing plates 11. The limit rings 16 are used to limit the geogrid.

[0026] The sliders 15 are limited by the sliding grooves 13, and the sliders 15 can drive the limit rings 16 to move inward to complete the limitation of the geogrid.

[0027] It should be noted that the present utility model is a geogrid asphalt coating device. When in use, first pour asphalt coating into the asphalt placement box 1. Then, the geogrid is pulled by an external pulling device, and the geogrid sequentially bypasses the second roller 12 and the first roller 3. The top of the geogrid contacts the bottom of the scraping plate 6, the bottom of the geogrid contacts the top of the notch 5, and under the elastic action of the tension spring 8 and the cooperation of the telescopic column 7 and the fixed disk 9, the side scraping plates 10 contact both sides of the geogrid. Therefore, the excess asphalt coating can be scraped off, ensuring the uniformity of asphalt coating, avoiding excessive coating, preventing the surface of the geogrid from being uneven, thus improving the coating effect. And the scraped asphalt falls into the asphalt placement box 1 below. Therefore, the asphalt coating can be recycled to save resources.

[0028] And by rotating the handwheel 17 to drive the bidirectional threaded rod 14 to rotate, due to the threading effect of the bidirectional threaded rod 14, the sliders 15 can move towards each other, thus driving the limit rings 16 to move and making the limit rings 16 contact both sides of the geogrid, thereby playing a limiting role to prevent the geogrid from shifting during pulling, so that geogrids with different widths can be limited, improving the practicability.
