Abstract
Description
Technical Field
[0001] This utility model is a construction site leveling device, belonging to the field of construction equipment. Background Technology
[0002] Before leveling a site, various preparatory work should be done, such as removing all above-ground and underground obstacles, draining standing water, and paving temporary roads. Currently, rollers are mostly used to flatten the road surface, but the use of existing construction site leveling equipment has at least the following drawbacks:
[0003] 1. During the use of existing construction site leveling devices, soil and gravel will adhere to the rollers. The soil can be scraped off and the rolling can continue without affecting the use. However, after the hard particles such as stones are scraped off, the levelness of the site will be affected. At the same time, the particles will damage the structure of the rollers.
[0004] 2. During the grading process, the outer surface of the pressure roller of the existing construction site grading device is prone to pits and holes due to long-term compression with hard particles, which affects the grading work. At the same time, it requires complete replacement during maintenance, which is costly and not conducive to use. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a construction site leveling device.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0007] A construction site leveling device includes a roller body. A front support is provided at the front end of the roller body. A pressure roller is rotatably connected inside the front support via a rotating shaft. A scraper assembly that cooperates with the pressure roller is provided on the inner wall of the front end of the front support. The scraper assembly includes a triangular scraper groove formed on the inner wall of the front end of the front support. The bottom sidewall of the triangular scraper groove cooperates with the pressure roller. Two sets of guide surfaces are symmetrically provided at the bottom of the triangular scraper groove. Screening elements are provided on the guide surfaces.
[0008] Furthermore, the guide surface includes an inclined surface and a straight surface. The inclined surface is located at the center of the inner bottom of the triangular scraper groove, and the straight surface is located at the inner bottom sidewall of the triangular scraper groove. The straight surface is in contact with the inclined surface.
[0009] Furthermore, the screening component includes a through hole, which is formed on the flat surface, and a filter element is snapped into the bottom of the through hole.
[0010] Furthermore, the filter element is either a filter screen or a mesh filter box.
[0011] Furthermore, the pressure roller includes a cylinder and an arc-shaped pressure plate. The center of the side of the cylinder is connected to the rotating shaft. Several sets of bolt holes are evenly opened on the outer surface of the side of the cylinder. The arc-shaped pressure plate presses on the outer surface of the cylinder. Connecting plates are fixed at both ends of the inner side of the arc-shaped pressure plate. Movable through holes are opened on the connecting plates. Bolts are inserted into the movable through holes. The bolts pass through the movable through holes and are connected and fixed to the bolt holes.
[0012] Furthermore, the outer surface of the cylinder is uniformly provided with several sets of positioning protrusions, and the arc-shaped pressure plate is provided with positioning holes that cooperate with the positioning protrusions.
[0013] Furthermore, a pad is provided between two adjacent sets of arc-shaped pressure plates, and an installation plate is fixed to the bottom of the pad. Several installation grooves that cooperate with the installation plate are evenly opened on the outer surface of the cylinder.
[0014] The beneficial effects of this utility model are:
[0015] This invention utilizes a scraping assembly and a pressure roller design to scrape off adhering materials from the outer surface of the pressure roller. Soil in the adhering materials can be sieved out, and stones can be collected and stored together to avoid interfering with the leveling of the site. The pressure roller is designed as a split structure consisting of a cylinder and several arc-shaped pressure plates, allowing for the replacement of damaged arc-shaped pressure plates used for site pressing when they become damaged.
[0016] This invention utilizes a scraping assembly design. When the pressure roller is on a level surface, and particles such as gravel and soil adhere to its outer surface, these particles will exceed the distance between the pressure roller and the triangular scraping groove as the pressure roller rotates and passes through it. The particles will be scraped off by the side wall of the triangular scraping groove and will enter the triangular scraping groove. The particles will then fall along the guide surface into the screening component for screening.
[0017] This invention, through the design of the guiding surface, allows particles entering the triangular scraper groove to fall quickly down the inclined surface to the flat surface, so that the particles can be gathered into the screening component for screening.
[0018] Through the design of the screening component, stones in the particles are guided into the through hole by the guide surface and then screened by the filter component. Meanwhile, the compacted soil clods are broken by the impact of the stones, and the broken soil clods are screened out by the filter component.
[0019] This invention, through the design of the filter element, allows for the sieving of small particles adhering to the pressure roller via a filter screen; and for larger particles, a mesh filter box can be used to collect several large particles.
[0020] This invention utilizes a pressure roller design to level a construction site during use. Furthermore, if one of the several arc-shaped pressure plates on the surface of the pressure roller is damaged, only the damaged arc-shaped pressure plate can be replaced, eliminating the need for a complete replacement.
[0021] This utility model, through the design of movable perforations, provides a small space for the curved pressure plate to move, thus avoiding damage to the bolts in the bolt holes caused by the thrust generated when the curved pressure plate is rigidly pressed against the ground.
[0022] This invention, through the design of positioning protrusions and positioning holes, not only facilitates the rapid positioning of the arc-shaped pressure plate, but also improves the stability between the arc-shaped pressure plate and the cylinder.
[0023] This utility model, through the design of an integrated structure of pad and mounting plate, not only fills the gap between two adjacent arc-shaped pressure plates to improve the integrity of the pressure roller, but also improves the strength and stability of the pad and mounting plate.
[0024] This invention improves the connection between the mounting plate and the cylinder by designing the mounting plate and mounting groove, thereby enhancing the stability of the pad. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Please see Figures 1-6 This utility model provides a technical solution for a construction site leveling device, including a road roller body 1. A front support 2 is provided at the front end of the road roller body 1. A pressure roller 14 is rotatably connected inside the front support 2 via a rotating shaft 3. A scraper assembly is provided on the inner wall of the front end of the front support 2, which cooperates with the pressure roller 14. The scraper assembly includes a triangular scraper groove 15 formed on the inner wall of the front end of the front support 2. The bottom sidewall of the triangular scraper groove 15 cooperates with the pressure roller 14. Two sets of guide surfaces are symmetrically arranged at the bottom of the trough 15, and screening components are provided on the guide surfaces. Through the design of the scraping assembly, when the pressure roller 14 is on a flat site, when its outer surface is covered with particles such as gravel and soil, when the pressure roller 14 rotates and passes through the triangular scraper 15, these particles will be higher than the distance between the pressure roller 14 and the triangular scraper 15. The particles will be scraped off by the side wall of the triangular scraper 15 and will enter the triangular scraper 15. The particles will fall along the guide surface into the screening components for screening.
[0035] See Figure 2 The guiding surface includes an inclined surface 16 and a straight surface 17. The inclined surface 16 is located at the center of the inner bottom of the triangular scraper groove 15, and the straight surface 17 is located at the inner bottom side wall of the triangular scraper groove 15. The straight surface 17 is in contact with the inclined surface 16. Through the design of the guiding surface, the particles entering the triangular scraper groove 15 will fall quickly down to the straight surface 17 through the inclined surface 16, so that the particles can be gathered to the screening component for screening.
[0036] See Figure 2The screening component includes a through hole 18, which is formed on the flat surface 17. A filter element 19 is attached to the bottom of the through hole 18. Through the design of the screening component, stones can be guided into the through hole 18 by the guide surface and then screened by the filter element 19. Meanwhile, the compacted soil clods will be broken by the impact of several stones, and the broken soil clods will be screened out by the filter element 19.
[0037] The filter element 19 is either a filter screen or a mesh filter box. Through the design of the filter element 19, when the particles adhering to the pressure roller 14 are small, they can be screened through the filter screen; if the particles adhering to the pressure roller 14 are large, several large particles can be collected through the mesh filter box.
[0038] See Figure 1 , Figures 3-5 The pressure roller 14 includes a cylinder 4 and an arc-shaped pressure plate 5. The center of the side of the cylinder 4 is connected to the rotating shaft 3. Several sets of bolt holes 8 are evenly opened on the outer surface of the side of the cylinder 4. The arc-shaped pressure plate 5 presses on the outer surface of the cylinder 4. Connecting plates 6 are fixed at both ends of the inner side of the arc-shaped pressure plate 5. The connecting plate 6 has a movable through hole 7. A bolt passes through the movable through hole 7 and is connected and fixed to the bolt hole 8. The design of the movable through hole 7 provides a small space for the arc-shaped pressure plate 5 to move, avoiding damage to the bolt in the bolt hole 8 caused by the thrust generated when the arc-shaped pressure plate 5 is rigidly pressed against the site. Through the design of the pressure roller 14, the construction site can be leveled when the device is in use. At the same time, if one of the arc-shaped pressure plates 5 on the surface of the pressure roller 14 is damaged, the damaged arc-shaped pressure plate 5 can be replaced without replacing the whole one.
[0039] See Figure 1 The outer surface of the cylinder 4 is uniformly provided with several sets of positioning protrusions 9, and the arc-shaped pressure plate 5 is provided with positioning holes 10 that cooperate with the positioning protrusions 9. Through the design of positioning protrusions 9 and positioning holes 10, the arc-shaped pressure plate 5 can be quickly positioned, while also improving the stability between the arc-shaped pressure plate 5 and the cylinder 4.
[0040] See Figure 1 , Figure 2 , Figure 4 , Figure 6A pad 13 is provided between two adjacent sets of arc-shaped pressure plates 5. The side wall of the pad 13 is provided with an elastic pad layer, which is pressed together with the side wall of the arc-shaped pressure plate 5. A mounting plate 12 is fixed to the bottom of the pad 13. Several mounting grooves 11 that cooperate with the mounting plate 12 are evenly opened on the outer surface of the cylinder 4. Through the design of the integrated structure of the pad 13 and the mounting plate 12, the pad 13 fills the gap between two adjacent arc-shaped pressure plates 5 to improve the integrity of the pressure roller 14, while also improving the strength and stability of the pad 13 and the mounting plate 12.
[0041] During use, when the pressure roller 14 is on a level surface, and its outer surface is covered with granular materials such as gravel and soil, as the pressure roller 14 rotates past the triangular scraper groove 15, these granules will exceed the distance between the pressure roller 14 and the triangular scraper groove 15. The granules will be scraped off by the side wall of the triangular scraper groove 15. The granules will then enter the triangular scraper groove 15 and fall quickly down the inclined surface 16 to the flat surface 17, allowing the granules to converge onto the screening element for screening. Stones in the granules will be guided by the guide surface into the through hole 18 and then screened. The filter element 19 performs screening and filtration. The compacted soil clods are broken up by impacts from several stones, and the broken soil clods are screened out by the filter element 19. When the device is in use, it can be used to level the construction site. At the same time, if one of the arc-shaped pressure plates 5 on the surface of the pressure roller 14 is damaged, the damaged arc-shaped pressure plate 5 can be replaced instead of replacing the whole device. Specifically, the bolts are removed from the bolt holes 8, and then the arc-shaped pressure plate 5 in that part is replaced and then fixed with bolts.
[0042] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
