Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, and more specifically, to a concrete pouring device. Background Technology

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete should not exceed 2m. If it exceeds 3m, corresponding measures should be taken.

[0003] Currently, when pouring concrete, the concrete is usually first poured into a mixing tank for mixing and then placed into a mold for pouring. Existing pouring equipment is prone to blockage on the inner wall of the discharge pipe during pouring, which will affect the discharge of material.

[0004] A search revealed that Chinese patent CN221834619U discloses a concrete pouring device. By activating an electric push rod, an arc-shaped plate can be moved, which in turn causes a rubber plate to gently tap the discharge pipe. Simultaneously, as the arc-shaped plate moves, an L-shaped plate slides within a groove. The movement of the arc-shaped plate is limited to prevent deviation and ensure better tapping of the discharge pipe, thus preventing blockage during pouring and achieving a better concrete pouring effect.

[0005] In actual use, the aforementioned concrete pouring device, as well as some existing concrete pouring devices, directly piles up the concrete, which is then spread and trimmed manually, increasing the intensity of manual labor, as well as construction time and costs. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete pouring device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A concrete pouring device includes a base plate, a support frame fixedly connected to the upper surface of the base plate, a leveling component installed inside the support frame, an arc-shaped scraper fixedly connected to the bottom of the support frame, a material bucket fixedly connected to the upper surface of the base plate, a scraping mechanism installed inside the material bucket, a pouring hose connected to the bottom end of the material bucket, a pouring head connected to one end of the pouring hose, a first movable frame fixedly connected to the outside of the pouring hose, the leveling component including a stepper motor, the stepper motor fixedly connected to one side of the support frame, a lead screw fixedly connected to the output end of the stepper motor, the lead screw being threadedly connected to the inside of the first movable frame, and a sliding column installed inside the support frame passing through the inside of the first movable frame.

[0008] By adopting the above technical solution, this utility model uses a stepper motor to drive the pouring head to move, so that the concrete is evenly spread.

[0021] The following will be based on the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application discloses a concrete pouring device, including a base plate 1, a support frame 2 fixedly connected to the upper surface of the base plate 1, a leveling component installed inside the support frame 2, an arc-shaped scraper 29 fixedly connected to the bottom of the support frame 2, a material bucket 3 fixedly connected to the upper surface of the base plate 1, a scraping mechanism installed inside the material bucket 3, a pouring hose 4 connected to the bottom end of the material bucket 3, a pouring head 5 connected to one end of the pouring hose 4, and a first movable frame 6 fixedly connected to the outside of the pouring hose 4.

[0023] The leveling assembly includes a stepper motor 7, which is fixedly connected to one side of the support frame 2. A drive wheel 8 is fixedly connected to the output end of the stepper motor 7. A chain 9 is engaged on the outer side of the drive wheel 8, and a driven wheel 10 is engaged on the inner side of the chain 9. A lead screw 11 is fixedly connected to one side of both the drive wheel 8 and the driven wheel 10. One lead screw 11 is threadedly connected to the inside of the first movable frame 6, and the other lead screw 11 is threadedly connected to the outside of the second movable frame 12. A first motor 13 is fixedly connected to the upper surface of the second movable frame 12. A rotating shaft 14 is fixedly connected to the output end of the first motor 13, and a rotating drum 15 is fixedly connected to the bottom end of the rotating shaft 14.

[0024] The support frame 2 has two sliding columns installed inside. The first movable frame 6 and the second movable frame 12 are slidably connected to the sliding columns. A turntable 16 is fixedly connected to the outside of the rotating shaft 14. Multiple first scrapers 17 are fixedly connected to the bottom of the turntable 16. Two flattening gear frames 18 are welded to the outside of the second movable frame 12. The drive wheel 8 is driven to rotate by the stepper motor 7. The drive wheel 8 and the driven wheel 10 are both meshed with the inside of the chain 9, so that the chain 9 can drive the drive wheel 8 and the driven wheel 10 to rotate. This allows the drive wheel 8 and the driven wheel 10 to drive the lead screw 11 to rotate. One lead screw 11 can drive the first movable frame 6 to move left and right, and the other lead screw 11 can drive the second movable frame 12 to move left and right. The threads of the two lead screws 11 are opposite, so that the first movable frame 6 and the second movable frame 12 can move alternately.

[0025] The second movable frame 12 can level the concrete poured by the pouring head 5 through the two leveling toothed frames 18 on the outside. Then, the first motor 13 drives the rotating shaft 14 to drive the rotating drum 15 and the turntable 16 to rotate. The turntable 16 drives multiple first scrapers 17 to scrape the uneven concrete. At the same time, the rotation of the rotating drum 15 can level the concrete. While moving the base plate 1, it can drive the arc-shaped scraper 29 to scrape the leveled concrete surface, so that the concrete can be kept flat. This effectively avoids the concrete accumulation or uneven distribution that occurs in traditional construction methods, thereby improving the overall construction efficiency.

[0026] Reference Figure 2 and Figure 6As shown, the scraping mechanism includes a housing 19, which is fixedly connected to the upper surface of the material barrel 3. A second motor 20 is fixedly connected to one side of the housing 19. A first bevel gear 21 is fixedly connected to the output end of the second motor 20. A second bevel gear 22 meshes with one side of the first bevel gear 21. The second bevel gear 22 is rotatably connected to the inside of the housing 19. A rotating rod 23 is fixedly connected to the bottom end of the second bevel gear 22. A spiral blade 24 is fixedly connected to the outside of the rotating rod 23. A third bevel gear 25 meshes with one side of the first bevel gear 21. The third bevel gear 25 is rotatably connected to the inside of the housing 19. A connecting rod 26 is fixedly connected to the lower surface of the third bevel gear 25. The connecting rod 26 is a tubular structure. The interiors of the third bevel gear 25 and the connecting rod 26 are rotatably connected to the rotating rod 23.

[0027] A rotating rod 27 is fixedly connected to the outside of the connecting rod 26. Two second scraper rods 28 are fixedly connected inside the rotating rod 27. A rotating rod 23 passes through the rotating rod 27 and is rotatably connected inside the rotating rod 27. The first bevel gear 21 meshes with the second bevel gear 22 and the third bevel gear 25, causing the second bevel gear 22 and the third bevel gear 25 to rotate in opposite directions. The second bevel gear 22 drives the spiral blades 24 to mix the concrete through the rotating rod 23. At the same time, the third bevel gear 25 drives the two second scraper rods 28 to scrape the inner wall of the material bucket 3 through the rotating rod 27, effectively scraping away the concrete adhering to the inner wall of the material bucket 3. This helps to reduce concrete residue and scale inside the material bucket 3 and ensures the fluidity of the concrete.

[0028] Working principle of this utility model: This utility model designs a concrete pouring device, the specific structure of which is shown in the attached instruction manual. Figures 1-6 As shown, in this technical solution, through the cooperation between various structures, when concrete needs to be poured, the concrete is first transported into the material bucket 3 through the feed pipe. Then, the second motor 20 is started, and the second motor 20 drives the first bevel gear 21 to rotate, so that the first bevel gear 21 meshes and drives the second bevel gear 22 to rotate clockwise. The second bevel gear 22 can drive the spiral blade 24 to mix the concrete through the rotating rod 23. At the same time, the first bevel gear 21 can mesh and drive the third bevel gear 25 to rotate counterclockwise, so that the third bevel gear 25 drives the rotating rod 27 to rotate through the connecting rod 26. The rotating rod 27 can drive the second scraper 28 to scrape the inner wall of the material bucket 3, thereby reducing the amount of concrete adhering to the inner wall of the material bucket 3.

[0029] Then, the valve is opened, allowing the mixed concrete to be poured through the pouring head 5 under the action of the pouring hose 4. Then, the stepper motor 7 is started, which drives the drive wheel 8 to rotate. Both the drive wheel 8 and the driven wheel 10 are engaged with the inner side of the chain 9, so that the chain 9 can drive the drive wheel 8 and the driven wheel 10 to rotate. The drive wheel 8 and the driven wheel 10 can drive the lead screw 11 to rotate. One lead screw 11 can drive the first movable frame 6 to move through the thread, so that the position of the pouring head 5 can be relatively changed during pouring, reducing concrete accumulation during pouring. At the same time, the other lead screw 11 can drive the second movable frame 12 to move through the thread, so that the first movable frame 6 and the second movable frame 12 move crosswise. The second movable frame 12 can spread the concrete poured by the pouring head 5 through the leveling tooth frame 18 on one side.

[0030] Then start the first motor 13, and use the first motor 13 to drive the rotating shaft 14 to rotate, so that the rotating shaft 14 can drive the rotating drum 15 and the turntable 16 to rotate. The turntable 16 can drive multiple first scrapers 17 to rotate. The multiple first scrapers 17 can sweep the raised concrete to one side. The rotating drum 15 can flatten the flat concrete. Then, by moving the base plate 1, the arc-shaped scraper 29 can be driven to scrape on the flat concrete, thereby maintaining the uniform thickness of the concrete.
