Description

Technical Field

[0001] This utility model belongs to the field of concrete production technology, and in particular relates to a sand and gravel feeding hopper for concrete production. Background Technology

[0002] In the concrete production industry, sand and gravel are core aggregates, and the stability and accuracy of their feeding process directly affect concrete quality and production efficiency. Currently, traditional sand and gravel feeding silos generally suffer from many technical bottlenecks: on the one hand, manual control of the unloading port opening and closing is inefficient and prone to errors, making it difficult to meet the rapid feeding needs of large-scale production and posing safety hazards; on the other hand, defects in the silo structure design lead to easy material segregation and moisture absorption, causing feeding blockages and frequent interruptions to the production process. At the same time, the lack of automated metering and anti-blocking devices makes it difficult to guarantee the continuity and uniformity of sand and gravel supply, resulting in fluctuations in concrete mix proportions and a decline in finished product quality. In addition, the dust pollution and noise exceeding standards caused by open silos also contradict the requirements of modern green and environmentally friendly production. Therefore, developing a new type of sand and gravel feeding silo with efficient feeding, precise control, intelligent anti-blocking, and environmental protection functions has become an urgent need to solve the existing pain points in concrete production and promote the technological upgrading of the industry.

[0003] However, existing feeding hoppers require workers to approach the feeding port to assist in opening and closing it. Manually opening and closing the baffle under the pressure of accumulated sand and gravel not only consumes a lot of time and manpower but also has low operating efficiency, making it difficult to match the rapid feeding requirements of automated production lines. Utility Model Content

[0004] The purpose of this utility model is to provide a sand and gravel feeding hopper for concrete production. By setting up a discharge section, it solves the problem that in the existing feeding hopper, workers need to approach the feeding port to assist in opening and closing the feeding port. Manually opening and closing the baffle under the pressure of sand and gravel accumulation not only consumes a lot of time and manpower, but also has low operating efficiency and is difficult to match the rapid feeding requirements of automated production lines.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a sand and gravel feeding hopper for concrete production, comprising a feeding hopper and several support legs fixedly connected to the feeding hopper, and further comprising: a discharge section installed on the feeding hopper; an agitation section disposed on the feeding hopper; the discharge section including a baffle assembly installed on the feeding hopper; and two switch assemblies, both disposed on the feeding hopper; the baffle assembly including two hinged plates fixedly connected to the bottom of the feeding hopper, each hinged with a baffle; a power component 1 disposed on the feeding hopper; wherein, four support legs are provided, the four support legs are arranged in a mirror image, the two hinged plates and the two baffles are also arranged in a mirror image; the power component 1 includes a motor frame fixedly connected to the front side of the feeding hopper, a motor 1 fixedly connected to the inner wall of the motor frame 1, and the output shaft of the motor 1 fixedly connected to a connecting rod located above via a coupling, leaving more space for the discharge port at the bottom of the feeding hopper, facilitating the subsequent installation of conveying equipment or metering devices.

[0007] Furthermore, the agitation unit includes a rotating shaft passing through the feeding hopper, the rotating shaft being rotatably connected to the feeding hopper, a circular roller being fixedly connected to the outer wall of the rotating shaft, and a plurality of stirring rods being fixedly connected to the outer wall of the circular roller. A power component two is provided on the front side of the feeding hopper; wherein, fifteen stirring rods are provided, and the fifteen stirring rods are distributed in an array. The power component two includes a motor frame two fixedly connected to the front side of the feeding hopper, a motor two being fixedly connected to the inner wall of the motor frame two, and the output shaft of the motor two being fixedly connected to the rotating shaft through a coupling. Even if sand and gravel with large particle size differences are mixed and piled up, uniform dispersion can be achieved through the shearing and tumbling action of the multi-layer stirring rods.

[0008] Furthermore, the switching assembly includes two connecting rods disposed on the front side of the feeding hopper. The upper connecting rod is rotatably connected to the feeding hopper, and the lower connecting rod is fixedly connected to the feeding hopper. A take-up roller is fixedly connected to the outer wall of the upper connecting rod, and a fixed roller is fixedly connected to the outer wall of the lower connecting rod. A sleeve is disposed on the fixed roller, and a connecting member is disposed on the take-up roller. The sleeve includes a fixed ring sleeved on the fixed roller, and the fixed ring is adapted to the fixed roller. The fixed ring is circular. The connecting member includes a steel wire rope disposed on the outer wall of the take-up roller, and the end of the steel wire rope is fixedly connected to the fixed ring. The steel wire rope is wound around the outer wall of the take-up roller, which can control the opening of the baffle to meet the feeding volume requirements under different production scenarios.

[0009] This utility model has the following beneficial effects:

[0010] 1. By setting up a discharge section, the motor drives the connecting rod to rotate, which drives the take-up roller to release the wire rope outward, thus slackening the wire rope. At this time, the lower take-up roller, fixed roller, and fixed ring are no longer constrained by the tension of the wire rope. The baffle opens outward under the pressure of the sand and gravel's own gravity. When the motor reverses, the connecting rod drives the take-up roller to rotate in the opposite direction, tightening the wire rope and pulling the take-up roller, fixed roller, and fixed ring inward. At the same time, it pulls the baffle to slide inward along the hinge plate until it is tightly fitted with the discharge bin, thereby accurately closing the discharge port. This achieves flexible start and stop control of sand and gravel discharge, avoids the tediousness and errors of manual operation, and significantly improves the stability and efficiency of material supply in the concrete production process.

[0011] 2. By setting up an agitator, mechanical external force breaks down the agglomeration and adhesion between sand and gravel caused by compression and moisture. During this process, the agitation of the mixing rod not only breaks up the dead corners of sand and gravel accumulation, but also effectively disperses sand and gravel particles, avoiding blockage of the discharge port caused by concentrated material accumulation. Through this dynamic mixing mechanism, the discharge port of the feeding hopper remains unobstructed, and sand and gravel can flow out stably and evenly, thereby ensuring the continuity of material supply in the concrete production line, reducing downtime maintenance time caused by blockage problems, and significantly improving production efficiency and material conveying stability.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

By setting the discharge part 2, the tediousness and error of manual operation are avoided, and the stability and efficiency of material supply in the concrete production process are significantly improved.

[0024] The agitator 3 includes a rotating shaft 311 that runs through the feeding hopper 111. The rotating shaft 311 is rotatably connected to the feeding hopper 111. A circular roller 312 is fixedly connected to the outer wall of the rotating shaft 311. Several stirring rods 313 are fixedly connected to the outer wall of the circular roller 312. A power unit 2 is provided on the front side of the feeding hopper 111. There are fifteen stirring rods 313 arranged in an array.

[0025] A specific application of this embodiment is as follows: In use, sand and gravel are first placed into the feeding hopper 111. Then, motor 214 on motor frame 213 is started. The connecting rod 221 will rotate accordingly. As the connecting rod 221 rotates, the take-up roller 222 is released outwards. With the release of the take-up roller 222, the fixed roller 223, and the fixed ring 224 located below are no longer pulled by the wire rope 225. At this time, the baffle 212 is squeezed open by the sand and gravel, and the sand and gravel flow out from the bottom of the feeding hopper 111. During the outflow, motor 315 on motor frame 314 is started. The rotating shaft 311 then rotates, causing the roller 312 and the stirring rod 313 to rotate. As the stirring rod 313 is rotated... When the machine is in motion, it will agitate the sand and gravel, which will prevent the sand and gravel from clogging the discharge port of the feeding hopper 111. When sand and gravel are not needed, the motor 214 will be started and reversed. At this time, the connecting rod 221 will reverse the winding roller 222. The winding roller 222 will then retract the wire rope 225 inward. When the wire rope 225 is retracted inward, the connecting rod 221, the fixed roller 223, and the fixed ring 224 located below will also be retracted inward. At this time, the baffle 212 will also retract inward. When the baffle 212 retracts inward, it will move on the hinge plate 211. With continuous movement, it will come into contact with the feeding hopper 111, thereby closing the baffle 212 and achieving the effect of closing the discharge port.

[0026] Finally, it should be noted that the above embodiments are merely illustrative examples for clearly illustrating the present invention, and are not intended to limit its implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, any obvious variations or modifications derived therefrom are still within the protection scope of this invention.
