Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, specifically to a green and low-carbon concrete construction operation device. Background Technology

[0002] The term concrete refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as a binder, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. Currently, in the construction industry, cement, water, stones and additives are usually mixed and stirred to make concrete.

[0003] In the current process of pouring green concrete, the surface needs to be smoothed. This smoothing requires the use of appropriate construction tools. The traditional method of concrete paving is for workers to pour concrete onto the road surface to be paved and then smooth it with a scraper. Because the construction tools are relatively simple in function, when the road surface is not smooth, the concrete paved in this way may be uneven, requiring secondary leveling by workers. This method is labor-intensive and inefficient. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 7 This invention provides a technical solution: a green and low-carbon concrete construction device, comprising: a vehicle body 1, a mixing tank 2 fixedly installed on one side of the upper end of the vehicle body 1, which facilitates the movement of the mixing tank 2 via the vehicle body 1; a feeding cylinder 3 fixedly installed on one side of the upper end of the mixing tank 2; a feeding hopper 4 fixedly installed on the upper end of the feeding cylinder 3; the lower end of the feeding cylinder 3 communicating with the mixing tank 2; a discharge pipe fixedly installed on the lower end of the mixing tank 2, the lower end of the discharge pipe being located below the vehicle body 1; a valve fixedly installed on the discharge pipe; the mixed concrete being discharged through the discharge pipe; a crushing component installed inside the feeding cylinder 3, which crushes stones; the crushed stones entering the mixing tank 2 and mixing with cement, sand, and other additives to form concrete, thus reusing the stones on the construction site.

[0028] The crushing components include a crushing roller 5, a rotating roller 8, and a screen plate 13. The rotating roller 8 is located at the lower end of the crushing roller 5, and the screen plate 13 is located at the lower end of the rotating roller 8. There are two crushing rollers 5, both of which are rotatably connected to the inside of the feed cylinder 3. One end of the shaft of the two crushing rollers 5 passes through the outer end of the feed cylinder 3 and is fixedly mounted with a gear 6. The outer walls of the two gears 6 are meshed with each other. A sprocket 10 is fixedly mounted on the outer side of one of the gears 6. When the sprocket 10 drives one gear 6 to rotate inward, it will simultaneously drive the other gear 6 to rotate inward, thereby driving the two crushing rollers 5 to rotate inward at the same time to crush the stones entering the feed cylinder 3.

[0029] The lower end of the crushing roller 5 is provided with an inclined plate 7, which is fixedly installed inside the feed cylinder 3. The lower end of the inclined plate 7 is in rotatable contact with the outer surface of the rotating roller 8. Several discharge troughs 9 are evenly opened on the outer wall of the rotating roller 8. The crushed stones fall onto the upper end of the inclined plate 7 for temporary storage. When the rotating roller 8 rotates, it will drive the discharge troughs 9 to rotate synchronously, conveying the crushed stones in the discharge troughs 9 to the upper end of the screen plate 13 below. The screen plate 13 is inclined and fixedly installed inside the feed cylinder 3. Opposite to the inclination direction of the inclined plate 7, the stones thrown out of the discharge chute 9 will fall on the upper end of the screen plate 13, and the unqualified stones will be screened out. The side wall of one end of the feed cylinder 3 is provided with a discharge port 14. The lower end of the discharge port 14 is flush with the upper side of the lower end of the screen plate 13. A discharge channel 15 is fixedly installed on the outer side of one end of the feed cylinder 3. The discharge channel 15 is located outside the discharge port 14. Unqualified stones roll into the discharge channel 15 from the discharge port 14 and then roll out from the discharge channel 15.

[0030] One end of the rotating shaft of the rotating roller 8 passes through the outer end of the feed cylinder 3 and is fixedly installed with a sprocket 10. A motor 11 is fixedly installed on the outer wall of one end of the feed cylinder 3. The output end of the motor 11 is fixedly connected to the outer wall of the sprocket 10. A chain 12 is connected to the outer wall of the two sprockets 10. When the motor 11 starts, it drives the sprocket 10 to rotate. When the sprocket 10 rotates, it starts the other sprocket 10 and the gear 6 to rotate through the chain 12, thereby simultaneously driving the crushing roller 5 and the rotating roller 8 to rotate. The rotating roller 8 throws the crushed stones evenly onto the upper end of the screen plate 13 to filter the stones.

[0031] A lifting plate 19 is mounted on the lower side of the other end of the vehicle body 1 via an adjustable component. The adjustable component includes two sliding rods 16 and two guide rods 20. The lower ends of the two sliding rods 16 slide through the vehicle body 1 and are fixedly connected to the upper end of the lifting plate 19. A connecting plate 17 is fixedly mounted on the upper end of the two sliding rods 16. A threaded rod 18 is threadedly connected to the center of the side wall of the connecting plate 17. The lower end of the threaded rod 18 passes through the side wall of the connecting plate 17 and is rotatably connected to the upper end of the vehicle body 1. The lower ends of the two guide rods 20 are fixedly mounted on the upper end of the lifting plate 19. The upper ends of the two guide rods 20 slide through the side wall of the vehicle body 1. By rotating the threaded rod 18, the threaded rod 18 drives the connecting plate 17 to slide on the vehicle body 1 with the sliding rods 16, thereby driving the lifting plate 19 to rise and fall at the lower end of the vehicle body 1. At the same time, the guide rods 20 slide on the vehicle body 1 to guide and limit the lifting plate 19.

[0032] A pressure cylinder 21 is rotatably connected to one side of the lower end of the lifting plate 19. A driving component is installed between the pressure cylinder 21 and the lifting plate 19. A trowel 29 is rotatably connected to the other side of the lower end of the lifting plate 19. A leveling plate 30 is fixedly installed at the rear end of the trowel 29. When the lifting plate 19 moves, it moves the pressure cylinder 21, the trowel 29, and the leveling plate 30 synchronously, which can smooth concrete of different thicknesses. An angle adjustment component is provided between the trowel 29 and the lifting plate 19. The angle adjustment component can adjust the angle between the trowel 29 and the leveling plate 30 and the concrete surface, which is convenient for leveling the concrete surface.

[0033] The driving component includes two round rods 22. The lower ends of the two round rods 22 are fixed to the front and rear sides of the support shell of the pressure cylinder 21, respectively. The upper end of each round rod 22 slides through the side wall of the lifting plate 19 and is fixedly installed with a limit plate 23. A spring 24 is sleeved on the outer wall of each round rod 22. The upper end of the spring 24 is fixed to the lower end of the limit plate 23, and the lower end of the spring 24 is fixed to the upper end of the lifting plate 19. When the spring 24 is in a balanced state, the support shell of the pressure cylinder 21 does not contact the lower end of the lifting plate 19. The pressure cylinder 21 shell moves up and down at the upper end of the lifting plate 19 by compressing or stretching the spring 24. A rack 25 is fixedly installed in the middle of the upper end of the support shell of the pressure cylinder 21. The rack 25 is perpendicular to the support shell. The upper end of the rack 25 slides through the lifting plate 19. The upper end of the lifting plate 19 is fixedly installed with a motor 26. The output end of the motor 26 is fixedly installed with a half gear 27. The outer wall of the half gear 27 meshes with the outer wall of the rack 25. When the motor 26 starts, it drives the half gear 27 to rotate. When the half gear 27 contacts the rack 25, it can push the rack 25 upward. The rack 25 moves the pressure cylinder 21 upward. When the half gear 27 and the rack 25 separate, they fall rapidly under the action of the spring 24 and the pressure cylinder 21's own weight. Through the rapid rotation of the half gear 27, the pressure cylinder 21 is reciprocated to move up and down within a small range. The pressure cylinder 21 rotates and moves up and down on the concrete while moving, flattening the concrete surface.

[0034] The lower end of the lifting plate 19 is fixedly equipped with rotating plates 28 on both the front and rear sides. The upper end of the trowel 29 is fixedly equipped with ear plates on both the front and rear sides. The ear plates and rotating plates 28 are rotatably connected. The trowel 29 can rotate at the lower end of the lifting plate 19. The angle adjustment component includes a circular hole opened on the lifting plate 19. A threaded sleeve 31 is rotatably connected in the circular hole. A threaded rod 32 is threadedly connected in the threaded sleeve 31. The lower end of the threaded rod 32 is rotatably connected to the upper end of the trowel 29. By rotating the threaded rod 32, the angle between the trowel 29, the leveling plate 30, and the concrete surface can be adjusted, which is convenient for leveling the concrete surface.

[0035] When this device is working, stones are put into the feed hopper 4, and the motor 11 is started to drive the crushing roller 5 and the rotating roller 8 to rotate. The crushing roller 5 crushes the stones, and the crushed stones fall to the upper end of the inclined plate 7. The rotating roller 8 throws the crushed stones evenly to the upper end of the screen plate 13 to filter the stones. The qualified stone fragments fall into the mixing tank 2 and are mixed with cement, sand and other additives to form concrete. Then the valve on the discharge pipe is opened, and the vehicle body 1 is pulled to the side where the concrete is discharged. The pressure cylinder 21 rotates and moves up and down on the concrete to vibrate the concrete surface. The trowel 29 and the leveling plate 30 level the concrete surface.

[0036] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
