Description

Technical Field

[0001] This utility model relates to the field of scraper technology for building construction, specifically a self-leveling scraper device. Background Technology

[0002] Self-leveling materials, as a type of highly fluid special floor leveling material, are widely used in indoor and outdoor floor construction. They can quickly form a flat, smooth, and solid floor base, meeting the needs of subsequent decoration or industrial site use. The conventional self-leveling construction process includes base treatment, application of interface agent, pouring and mixing the self-leveling slurry. After the material spreads naturally due to its own fluidity, a scraper is needed to assist in spreading and defoaming.

[0003] However, existing scrapers have significant drawbacks in practical applications: tiny particles (such as residual pebbles, sand, and hardener clumps) that are difficult to completely remove from the substrate or self-leveling slurry are easily covered by the slurry and not effectively treated by the scraper. During the later curing process of the self-leveling material, these impurities can hinder uniform solidification, creating localized stress concentration points, or causing problems such as hollowing and cracking due to their own moisture absorption and expansion, severely damaging the integrity and durability of the floor and increasing subsequent maintenance costs.

[0004] To address these issues, this invention provides a self-leveling scraper device. Summary of the Invention

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 5 This application provides a self-leveling scraper device, including a fixed base 1 and a telescopic rod 2 movably mounted on the fixed base 1. A filter element 13 is installed inside the fixed base 1, and the filter element 13 divides the inner cavity of the fixed base 1 into upper and lower parts. An inclined scraper 12 for scraping the self-leveling material is installed on the back of the fixed base 1. A moving component 3 for assisting in leveling and facilitating the movement of the device is rolled on the lower part of the fixed base 1. A slag discharge component 5 for cleaning impurities in its inner cavity is provided on the upper part of the fixed base 1. A defoaming component 6 for eliminating air bubbles on the surface of the self-leveling material is slidably provided on the front part of the fixed base 1.

[0020] A feed pipe 11 is connected through the top of the fixed base 1 on the side away from the middle. The self-leveling material is introduced into the upper inner cavity of the fixed base 1 through the external pipe and the feed pipe 11. A feed slot 14 is opened on the upper side of the back end of the fixed base 1 and communicates with the upper inner cavity of the fixed base 1. The inclined scraper 12 is fixedly installed on the fixed base 1 and located below the feed slot 14. The feed slot 14 can help collect the self-leveling material and impurities scraped back by the inclined scraper 12 to achieve secondary filtration.

[0021] The bottom of the fixed base 1 is open to facilitate the downward flow of the filtered self-leveling material. A rotating shaft 31 is rotatably connected through the inner wall of the lower inner cavity of the fixed base 1 along its height direction. Both sides of the rotating shaft 31 are fixedly connected to the traveling wheels 33 to drive the overall movement of the device. A rotating roller 32 is coaxially fixedly connected to the middle of the outer surface of the rotating shaft 31. The outer surface of the rotating roller 32 extends to the outside of the fixed base 1 through the lower port of the fixed base 1. When the rotating roller 32 rotates with the rotating shaft 31, it can evenly spread the filtered self-leveling material to the ground and expand the paving area.

[0022] The defoaming component 6 includes two slip rings 61, two guide rods 622, a crossbar 62, and several support rods 621. The two slip rings 61 are symmetrically fixedly installed on the upper front side of the fixed base 1 to provide sliding support for the guide rods 622. The two guide rods 622 are slidably connected in the corresponding slip rings 61 and can slide up and down along the slip rings 61 to adapt to different thicknesses of slurry layers. The crossbar 62 is fixedly connected to the bottom end of the two guide rods 622, and several support rods 621 are equidistantly fixedly connected to the bottom end of the crossbar 62. The support rods 621 are distributed in a comb-like manner, which can efficiently puncture air bubbles on the surface of the slurry and prevent air bubbles from being trapped in the deep layer, causing delamination.

[0023] The slag discharge assembly 5 includes a slag discharge port 51, an opening and closing cover plate 52, several connecting rods 53, and a pull block 54. The slag discharge port 51 is opened through the top of the fixed base 1 on the side away from the middle, and is used to discharge impurities. The opening and closing cover plate 52 is slidably connected to the slag discharge port 51 and can realize the opening and closing of the slag discharge port 51. In the non-slag cleaning state, the slag discharge port 51 can be closed to prevent material leakage. The pull block 54 is slidably arranged in the upper inner cavity of the fixed base 1. Several connecting rods 53 are symmetrically connected between the opening and closing cover plate 52 and the pull block 54. When the opening and closing cover plate 52 is pulled, the pull block 54 can be moved synchronously through the connecting rods 53 to push the impurities accumulated in the upper inner cavity of the fixed base 1 out of the slag discharge port 51.

[0024] A ball seat 22 is installed at the top center of the fixed seat 1. A ball head 21 is movably connected inside the ball seat 22. The ball head 21 is fixedly connected to the bottom end of the telescopic rod 2. The cooperation between the ball head 21 and the ball seat 22 can realize the multi-angle rotation of the telescopic rod 2, which makes it easy for the operator to adjust the tilt angle of the device and adapt to different construction scenarios such as paving at the edge of the ground and corners.

[0025] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0026] Working principle: The self-leveling material is injected into the upper inner cavity of the fixed base 1 through the feed pipe 11 by the feed pump. It first flows through the filter element 13 inside the fixed base 1 for initial filtration, removing impurities such as curing agent clumps. The filtered material flows through the lower port of the fixed base 1 to the surface of the rotating roller 32 of the moving component 3. At this time, the fixed base 1 slides on the ground via the traveling wheels 33 of the moving component 3, and the rotating shaft 31 synchronously drives the rotating roller 32 to rotate. The rotating roller 32 uses centrifugal force to throw the self-leveling material on the surface to both sides of the ground, achieving initial spreading. Simultaneously, the inclined scraper 12 on the back of the fixed base 1 moves with the device, further leveling the material that is not fully spread on the ground and removing any remaining material. Small stones, sand, and other impurities, along with some material, are shoveled back into the upper inner cavity of the fixed seat 1 through the feed trough 14, and then filtered again by the filter element 13 to completely intercept the impurities. In the defoaming component 6 at the front of the fixed seat 1, the support rod 621 at the bottom of the crossbar 62 moves with the device, which can efficiently puncture the air bubbles on the surface of the material and prevent hollowing later. When impurities accumulate in the upper inner cavity of the fixed seat 1, the opening and closing cover plate 52 of the slag discharge component 5 is pulled, and the pull block 54 is driven to slide through the connecting rod 53, pushing the impurities on the surface of the filter element 13 out of the slag discharge trough 51 for cleaning. In addition, the ball head 21 at the bottom of the telescopic rod 2 can move in the ball seat 22 at the top of the fixed seat 1, which makes it easy to adjust the tilt angle of the fixed seat 1 and adapt to different construction scenarios.
