[0026] 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.

[0027] Example 1: Please refer to Figure 1-7This utility model provides a technical solution: a concrete leveling device for concrete pouring, comprising a device body 1 and a vibrating box 3; a first leveling plate 4 is installed at one end of the device body 1, and symmetrical second leveling plates 5 are installed on the side of the first leveling plate 4; a scraping mechanism 2 is installed at one end of the first leveling plate 4; the scraping mechanism 2 includes a fixing strip 21 installed at one end of the first leveling plate 4, a movable block 22 slidably installed at one end of the fixing strip 21, a limit groove 23 is opened at one end of the fixing strip 21, and circular grooves 24 are opened on the side of the fixing strip 21 and the movable block 22; a roller 25 is installed at one end of the movable block 22, and a plurality of ball bearings 26 are installed in the circular groove 24; the movable block 25... One end of the device 2 is fitted with a limiting block 27 that matches the limiting groove 23. One end of the movable block 22 is fitted with a second motor 28. A trapezoidal scraper 29 is fitted at the bottom of the movable block 22. The side of the first flat plate 4 matches the trapezoidal scraper 29. The main body 1 of the device is fitted with a first motor 8. One end of the first motor 8 is fitted with a transmission rod 9. One end of the transmission rod 9 is fitted with an eccentric block 10. The vibration box 3 matches the eccentric block 10. One end of the fixing strip 21 is fitted with a motor housing 14. The motor housing 14 matches the second motor 28. Multiple limiting pins 15 are fitted on the side of the fixing strip 21. The limiting pins 15 match the movable block 22. One end of the roller 25 matches the second motor 28. The output end is connected, and the roller 25 is rotatably mounted on the side of the fixed strip 21. When it is necessary to level the concrete, the first motor 8 in the main body 1 of the starting device drives the transmission rod 9 to rotate. The vibration generated by the transmission rod 9 driving the eccentric block 10 to rotate causes the first leveling plate 4 to vibrate the concrete. When the first leveling plate 4 vibrates the concrete, some concrete may adhere to the side of the first leveling plate 4 when it is dragged backward. It is necessary to remove the adhered concrete. The second motor 28 is started to drive the roller 25 to rotate. One end of the roller 25 abuts against the side of the fixed strip 21 and has a certain friction. The rotation of the roller 25 can drive the movable block 2 2. Slide on the fixed strip 21. When the movable block 22 slides, multiple balls 26 installed in the movable block 22 rotate in the circular groove 24, making the movable block 22 slide more easily. The movable block 22 moves under the limit of the limiting block 27 and drives the trapezoidal scraper 29 at the bottom to move. Both ends of the trapezoidal scraper 29 are provided with inclined surfaces and are in contact with the side of the first flat plate 4. The movement of the trapezoidal scraper 29 scrapes off any concrete that may be attached to the first flat plate 4 and drops it into the remaining concrete, making it easier for the operator to continue to flatten the concrete. By inserting the limiting nail 15 into the preset holes of the first flat plate 4 and the second flat plate 5, the range of movement of the movable block 22 is limited.

[0028] Example 2: As Figure 3-7As shown, a handle 6 is installed at one end of the main body 1 of the device, and an anti-slip sleeve 7 is installed at one end of the handle 6. A connecting block 11 is installed on the side of the first flat plate 4. A connecting groove 12 adapted to the connecting block 11 is opened at one end of the second flat plate 5. A fixing bolt 13 is installed at one end of the connecting block 11. A movable groove 16 is opened inside the handle 6. A sliding column 17 is slidably installed at one end of the movable groove 16. A spring 18 is installed at one end of the sliding column 17. The other end of the spring 18 is installed on the inner wall of the movable groove 16. When the main body 1 of the device is used in different scenarios, the range of concrete leveling may be adjusted. The second flat plate 5 can be connected by the connecting block 11 on the side of the first flat plate 4. The connecting block 11 is installed correspondingly to the connecting groove 12. The connection position of the connecting block 11 and the connecting groove 12 is fixed by the fixing bolt 13, thereby connecting the first flat plate 4 and the second flat plate 5. The second flat plate 5 is provided with a structure that is compatible with the fixing strip 21, which facilitates the movement of the movable block 22, increases the overall length of the first flat plate 4, and thus increases the range of single-time concrete leveling, improving the applicability of the main body 1 of the device. One end of the handle 6 is equipped with a sliding column 17. When in use, the sliding column 17 slides in the movable groove 16, continuously compressing and rebounding the spring 18, helping the user to reduce the vibration force brought by the device, making it more stable during use. The remaining features are the same as in Embodiment 1.

[0029] The working principle is as follows: When it is necessary to level the concrete, the first motor 8 inside the main body 1 of the starting device drives the transmission rod 9 to rotate. The vibration generated by the transmission rod 9 driving the eccentric block 10 to rotate causes the first leveling plate 4 to vibrate and level the concrete. When the first leveling plate 4 vibrates the concrete, some concrete may adhere to the side of the first leveling plate 4 when it is dragged backward. It is necessary to remove the adhered concrete. The second motor 28 is started to drive the roller 25 to rotate. One end of the roller 25 is in contact with the side of the fixing strip 21. The roller 25 provides friction, and the rotation of the roller 25 causes the movable block 22 to slide on the fixed strip 21. When the movable block 22 slides, multiple balls 26 installed inside the movable block 22 rotate in the circular groove 24, making the movable block 22 slide more easily. The movable block 22 moves under the limit of the limiting block 27 and drives the trapezoidal scraper 29 at the bottom to move. Both ends of the trapezoidal scraper 29 are provided with inclined surfaces and are in contact with the side of the first flat plate 4. The movement of the trapezoidal scraper 29 removes any concrete that may be attached to the first flat plate 4. Soil is scraped off and falls into the remaining concrete, making it easier for operators to continue leveling the concrete. By inserting the limiting nail 15 into the preset holes of the first leveling plate 4 and the second leveling plate 5, the range of movement of the movable block 22 is limited. When the main body of the device 1 is used in different scenarios, the range of concrete leveling may be adjusted. The second leveling plate 5 can be connected by the connecting block 11 on the side of the first leveling plate 4. The connecting block 11 is installed in correspondence with the connecting groove 12. The connection position of the connecting block 11 and the connecting groove 12 is fixed by the fixing bolt 13, thereby connecting the first leveling plate 4 and the second leveling plate 5. The second leveling plate 5 is provided with a structure that is adapted to the fixing strip 21, which facilitates the movement of the movable block 22, increases the overall length of the first leveling plate 4, and thus increases the range of concrete leveling in a single operation, improving the applicability of the main body of the device 1. One end of the handle 6 is equipped with a sliding column 17. When in use, the sliding column 17 slides in the movable groove 16, constantly compressing and rebounding the spring 18, helping the user reduce the vibration force brought by the device, making it more stable during use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
