Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a device for preventing segregation and stratification during concrete pouring. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio. Concrete pouring requires a concrete feeding device, which is used in concrete construction to transport concrete accurately and evenly. It is typically used in situations requiring vertical or horizontal concrete transport, such as the pouring of high-rise buildings, elevated structures, and underground foundations.

[0003] In existing technologies, the speed and drop of concrete falling are very large, resulting in severe segregation and slump issues, which in turn greatly affect the quality of the concrete.

[0004] This invention proposes a concrete pouring and discharge anti-segregation device to solve the problem of concrete segregation caused by large falling speed and drop. Summary of the Invention

[0005] In order to overcome the problem of concrete segregation caused by the large falling speed and drop of concrete in the above-mentioned background technology.

A large gear is fixedly sleeved on the outside of the drive shaft. A driven shaft is fixedly connected to the top of each of the two sets of rotating rods. The tops of the two sets of driven shafts are rotatably connected to the inner top wall of the housing. A small gear is fixedly sleeved on the outside of the two sets of driven shafts for meshing with the large gear.

[0012] As a further limitation of the above technical solution, baffles are fixedly connected to both the front and rear ends of the top of the buffer plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention solves the segregation problem caused by high-drop pouring by arranging multiple buffer plates in a staggered manner inside the pouring box, thereby reducing the drop height and speed of the concrete and ensuring its strength.

[0018] This invention uses a drive structure to rotate a rotating rod, which in turn drives the spiral blades, L-shaped mixing shaft, and L-shaped mixing shaft to rotate. This allows for uniform mixing of the upper and lower layers of concrete, ensuring thorough mixing before pouring and preventing segregation. This further improves the quality of the concrete before pouring.

[0019] This invention uses a vibrating motor to vibrate the feeding box, and with the cooperation of multiple buffer structures, the feeding box shakes up and down as a whole, which helps to reduce the adhesion of cement paste and coarse aggregate in concrete and effectively improves the fluidity of concrete.

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a device for preventing segregation and stratification during concrete pouring, such as... Figure 1 As shown, this invention addresses the problem of concrete segregation caused by large falling speeds and drops. It includes a feeding hopper 1, with a mixing structure 2 installed on the inner top wall of the feeding hopper 1. A driving structure 3 is installed on top of the mixing structure 2. The driving structure 3 is located at the top of the feeding hopper 1. A partition 4 is fixedly installed inside the feeding hopper 1 near the mixing structure 2. A discharge port 5 is opened on one side of the partition 4. A buffer plate 6 is staggered and arranged inside the feeding hopper 1 near the discharge port 5. A feed pipe 7 is fixedly connected to the top of one side of the feeding hopper 1, and a discharge pipe 8 is fixedly connected to one side of the bottom of the feeding hopper 1. The driving structure 3 drives the mixing structure 2 to rotate.

[0027] Combination Figure 1In the embodiments of this utility model, both the feed port 5 and the discharge pipe 8 are equipped with solenoid valves.

[0028] Combination Figure 1 and Figure 2 In the embodiments of this utility model, baffles 61 are fixedly connected to both the front and rear ends of the top of the buffer plate 6.

[0029] Combination Figure 1 In an embodiment of this utility model, a guide seat 11 is installed at an incline on the top of the partition 4, and the lower end of the guide seat 11 is fixedly connected to the discharge port 5.

[0030] Concrete is added into the feed box 1 through the feed pipe 7. The mixing structure 2 is driven by the drive structure 3 to rotate and mix the concrete. The solenoid valves inside the discharge port 5 and the discharge pipe 8 are opened. Under the guidance of the guide seat 11, the concrete falls into the top of the upper buffer plate 6 through the discharge port 5. The front and rear ends of the buffer plate 6 are blocked by the baffle 61, and multiple buffer plates 6 are staggered inside the feed box 1. Finally, the concrete is discharged through the discharge pipe 8. This reduces the falling height and slows down the falling speed of the concrete during pouring, solving the segregation problem caused by high drop pouring and ensuring the strength of the concrete.

[0031] Example 2: Reference Figure 1 To address the issue of concrete separation caused by the separation of components, resulting in uneven internal composition and structure, the mixing structure 2 includes two sets of rotating rods 21, which are rotatably connected to both ends of the inner top wall of the feeding box 1. Spiral blades 22 are connected at equal intervals on the outer sides of the two sets of rotating rods 21. L-shaped mixing shafts 23 are fixedly connected to the top of both sides of the two sets of rotating rods 21, and mixing rods 24 are fixedly connected at equal intervals on both sides of the L-shaped mixing shafts 23.

[0032] Combination Figure 1 In an embodiment of this utility model, the drive structure 3 includes a housing 31, which is fixedly installed on the top of the feeding box 1. A drive motor 32 is installed inside the housing 31. A drive shaft 33 is fixedly connected to the top of the drive motor 32. The top of the drive shaft 33 is rotatably connected to the inner top wall of the housing 31. A large gear 34 is fixedly sleeved on the outer side of the drive shaft 33. A driven shaft 35 is fixedly connected to the top of each of the two sets of rotating rods 21. The tops of the two sets of driven shafts 35 are rotatably connected to the inner top wall of the housing 31. A small gear 36 is fixedly sleeved on the outer side of the two sets of driven shafts 35 for meshing with the large gear 34.

[0033] After concrete is added into the material box 1, the drive motor 32 is started. When the drive motor 32 is working, it drives the large gear 34 to rotate through the drive shaft 33. Since the large gear 34 is meshed with the small gear 36, the rotation of the large gear 34 drives the small gear 36 to rotate. The rotation of the small gear 36 drives the two sets of driven shafts 35 to rotate, which in turn drives the two sets of rotating rods 21 to rotate. When the rotating rods 21 rotate, they drive the spiral blades 22 to rotate, so that the concrete is conveyed from bottom to top. At the same time, the rotation of the rotating rods 21 drives the L-shaped mixing shaft 23 and the mixing rod 24 to rotate, which can mix the concrete. This ensures that the concrete is fully mixed and evenly mixed before pouring, avoiding the separation of concrete layers and further improving the quality of the concrete before pouring.

[0034] Example 3: Reference Figure 1 and Figure 3 To address the issue that heavy coarse aggregates may settle at the bottom of the feeding box and cause stratification due to the high viscosity of concrete during the feeding process, buffer structures 9 are provided on both sides of the bottom of the feeding box 1, and a vibration motor 10 is fixedly installed at the bottom of the feeding box 1.

[0035] Combination Figure 1 and Figure 3 In an embodiment of this utility model, the buffer structure 9 includes four sets of support plates 91. A cylinder 92 is fixedly installed on the top of each of the four sets of support plates 91. A sliding plate 93 is slidably installed inside each of the four sets of cylinders 92. A buffer spring 94 is fixedly connected to the bottom of each of the four sets of sliding plates 93 and the inner bottom wall of each of the cylinders 92. A movable column 95 is fixedly connected to the top of each of the four sets of sliding plates 93. The top of each of the four sets of movable columns 95 extends out of the cylinder 92 and is fixedly installed with a connecting plate 96. The inner side of each of the four sets of connecting plates 96 is fixedly connected to the outer side of the feeding box 1.

[0036] During the concrete feeding process, the vibration motor 10 is started, and the vibration motor 10 drives the feeding box 1 to vibrate. When the feeding box 1 vibrates, the connecting plate 96 drives the movable column 95 to move up and down inside the cylinder 92. When the cylinder 92 moves, the sliding plate 93 stretches or compresses the buffer spring 94, thereby causing the feeding box 1 to shake up and down as a whole, thereby reducing the adhesion of cement paste and coarse aggregate in the concrete and effectively improving the fluidity of the concrete.

[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
