Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to a feeding uniform distribution device suitable for concrete piles. Background Technology
[0002] In the production process of concrete piles, the uniformity of material feeding plays a crucial role in the quality of the concrete piles. Uniform feeding ensures consistent strength and performance across all parts of the concrete pile, avoiding structural defects caused by localized material accumulation or loss, thereby improving the overall quality and reliability of the concrete piles. Therefore, uniform material distribution equipment suitable for concrete piles is widely used in production lines.
[0003] Existing feeding and uniform distribution equipment mostly employs complex internal structures and integrated designs. While these can achieve uniform feeding and distribution to a certain extent, they also have drawbacks during use. Due to the strong viscosity and hardening properties of concrete, residual concrete easily adheres to the inner walls, pipes, valves, and other components of the equipment during the feeding process. When cleaning is required, some internal dead corners are difficult to clean thoroughly. The solidified residual concrete can affect the normal operation of the equipment, reduce the uniformity and accuracy of feeding, increase maintenance costs, and even shorten the equipment's lifespan, thus impacting the production efficiency of concrete piles. Therefore, this utility model proposes a novel solution. Utility Model Content

[0028] Please see Figure 1-4This utility model provides a technical solution: a uniform feeding and distributing device suitable for concrete piles, including a concrete silo 1 and a concrete feeding silo 2. The concrete feeding silo 2 is inclinedly arranged below the concrete silo 1. A feeding assembly is arranged on the concrete feeding silo 2. The feeding assembly includes a feeding silo inlet pipe 4, which is fixedly connected to the upper end of the concrete feeding silo 2. A silo discharge pipe 3 is fixedly connected to the lower end of the concrete silo 1. The silo discharge pipe 3 and the silo inlet pipe 4 are connected by a screw... The material discharge pipe 3 and the feed pipe 4 of the feeding hopper are both inclined and fixed. The side wall of the concrete feeding hopper 2 is fixedly connected to the first feed pipe 9. The bottom of the concrete feeding hopper 2 is fixedly connected to the second drive motor 12. The output end of the second drive motor 12 extends into the interior of the concrete feeding hopper 2 and is fixedly connected to three agitators 13. All three agitators 13 are in contact with the bottom surface inside the concrete feeding hopper 2. The side wall of the concrete feeding hopper 2 is fixedly connected to two second feed pipes 10.
[0029] The feeding assembly also includes a fixed bracket 5, which is inclinedly arranged inside the concrete hopper 1. A first drive motor 6 is fixedly connected to the upper end of the fixed bracket 5. A rotating shaft 7 is fixedly connected to the output end of the first drive motor 6. A concrete conveying blade 8 is fixedly connected to the surface of the rotating shaft 7. Both the rotating shaft 7 and the concrete conveying blade 8 extend into the interior of the hopper discharge pipe 3. Both the rotating shaft 7 and the concrete conveying blade 8 are inclinedly arranged.
[0030] The pitch of the concrete conveying blades 8 decreases sequentially from top to bottom.
[0031] The first feed hopper discharge pipe 9 and the two second feed hopper discharge pipes 10 are arranged in a circular array on the side of the concrete feed hopper 2. Each of the two second feed hopper discharge pipes 10 is provided with a sealing flange 11 on the side away from the concrete feed hopper 2. Both sealing flanges 11 are fixed to the corresponding second feed hopper discharge pipe 10 by bolts.
[0032] The concrete silo 1 is funnel-shaped, and the lower left side of the concrete silo 1 is an inclined plane.
[0033] A vibration motor 14 is fixedly installed at the lower end of the concrete silo 1.
[0034] When using the device, concrete raw materials are stored in a funnel-shaped concrete silo 1. The inclined plane design at the lower left end of the silo guides the raw materials to gather towards the center and avoids accumulation. The vibration motor 14 is installed at the bottom of the concrete silo 1 and eliminates the arching effect of the raw materials through vibration to ensure smooth material feeding.
[0035] The fixed support 5 is inclinedly set inside the concrete silo 1. The first drive motor 6 at its upper end drives the rotating shaft 7 and the concrete conveying blades 8 to rotate. The pitch of the concrete conveying blades 8 decreases from top to bottom, forming a tapered conveying structure. The upper pitch is large, which quickly grabs the raw materials. The lower pitch is small, which squeezes and pushes the raw materials to achieve quantitative conveying, avoids material spillage, and improves the uniformity of concrete conveying. The raw materials are stably conveyed to the concrete feeding silo 2 through the inclined channel of the silo discharge pipe 3 and the feeding silo inlet pipe 4.
[0036] The concrete feeding hopper 2 is set at an angle, and the second drive motor 12 at the bottom drives three mixing blades 13 to rotate in contact with the bottom of the hopper, so as to perform secondary mixing on the incoming concrete, eliminate lumps and homogenize it.
[0037] The mixed concrete is discharged through the discharge pipe 9 of the first feeding hopper, which serves as the main discharge channel; the two discharge pipes 10 of the second feeding hopper are arranged in a ring array on the side of the hopper to assist in diversion and ensure synchronous and uniform feeding at multiple workstations.
[0038] When only a single-channel discharge is required, the sealing flange 11 is bolted to seal the unused second feeding bin discharge pipe 10 to prevent leakage; when multiple channels of feeding are required, the sealing flange 11 is disassembled to achieve multi-port diversion; the inclined concrete feeding bin 2 structure, in conjunction with the pushing of the mixing paddle 13, utilizes the combined action of gravity and mechanical force to ensure that the concrete flows towards the first feeding bin discharge pipe 9 and the second feeding bin discharge pipe 10, avoiding stagnation.
[0039] The discharge pipe 3 of the silo and the feed pipe 4 of the feed silo are connected by bolts. They can be quickly disassembled when cleaning is required to separate the concrete silo 1 and the concrete feed silo 2, making it easy to clean the internal residues separately.
[0040] The bolted connection between the sealing flange 11 and the discharge pipe 10 of the second feeding bin allows the unused discharge port to be opened, fully exposing the interior of the concrete feeding bin 2. Operators can insert cleaning tools at multiple angles through the discharge pipe 9 of the main first feeding bin and the discharge pipe 10 of the auxiliary second feeding bin, eliminating or reducing the problem of dead corner residue in traditional equipment.
[0041] The mixing paddle 13 is designed to fit the bottom of the silo, which can scrape off the concrete adhering to the bottom; the inclined silo body and the inner wall of the pipe reduce the surface area where raw materials are retained, and combined with the auxiliary vibration of the vibration motor 14, the risk of residue is further reduced; after disassembly, each component can be rinsed or soaked separately, avoiding the difficulty of cleaning after the concrete has hardened, significantly reducing maintenance costs and extending the service life of the equipment.
[0042] Furthermore, the discharge pipe 3 of the silo and the feed pipe 4 of the feed silo are connected by bolts. When cleaning is required, the concrete silo 1 and the concrete feed silo 2 can be quickly disassembled and separated, which facilitates independent cleaning of the two cavities and avoids the cleaning blind spots of the traditional integrated structure. The bolt connection design between the sealing flange 11 and the discharge pipe 10 of the second feed silo can open the idle discharge port to completely expose the interior of the concrete feed silo 2. Operators can use the main first feed silo discharge pipe 9 and the auxiliary second feed silo discharge pipe 10 to insert cleaning tools at multiple angles to thoroughly remove residual concrete from the inner wall, pipes and bottom of the mixing paddle 13, solving the problem of solidification residue caused by dead corners in traditional equipment.
[0043] The three mixing paddles 13 at the bottom of the concrete feeding hopper 2 rotate in contact with the bottom of the hopper to perform secondary mixing of the concrete, eliminate lumps and homogenize it. At the same time, in conjunction with the inclined hopper design, the mixed concrete is pushed to the discharge pipe 9 of the first feeding hopper and the discharge pipe 10 of the second feeding hopper by the combined action of gravity and mechanical force, so as to achieve synchronous and uniform feeding of multiple stations, avoid local accumulation or missing parts, and ensure that the strength and performance of each part of the concrete pile are consistent.
[0044] The first feed bin discharge pipe 9 and the two second feed bin discharge pipes 10 are arranged in a ring array. The single-channel or multi-channel feeding mode can be flexibly switched through the sealing flange 11. In the single-channel mode, the idle discharge port is closed to avoid material leakage. In the multi-channel mode, the flow is split synchronously to adapt to different production line layouts and significantly improve the flexibility and uniformity of feeding.
