Description

Technical Field

[0001] This utility model relates to the field of concrete conveying technology, and in particular to a raw material conveying device for concrete production. Background Technology

[0002] In the construction industry, concrete is an extremely important building material with a wide range of applications, covering the construction of various buildings, roads, bridges, and other infrastructure. Concrete is composed of aggregates, cement, and water, among which coarse aggregates play a crucial role as the skeleton and are mostly in the form of single-size or discontinuous-size aggregates. With the continuous development of the construction industry, higher requirements have been placed on the quality and production efficiency of concrete, and the production processes and equipment of concrete mixing plants are constantly being improved and optimized.

[0003] In concrete mixing plants, conveyor belts are commonly used to transport concrete raw materials to the mixing tanks. Due to limited plant space, it is difficult to transport concrete raw materials to the correct location in one go. Therefore, the industry typically uses multiple conveyor belts arranged at an angle to transport the raw materials in a circuitous manner. In practice, the raw materials are first added to the first conveyor belt through a hopper. When the raw materials reach the end of the first conveyor belt, they fall onto a second conveyor belt arranged at an angle to the first conveyor belt, thus achieving the transportation of the raw materials.

[0004] The existing technology of using multiple conveyor belts arranged at an angle to transport raw materials has certain drawbacks. When raw materials fall from the first conveyor belt into the second conveyor belt, it will cause a large impact on the second conveyor belt. This impact will not only affect the service life of the conveyor belt, but may also cause the raw materials to spill during the transportation process, which is not conducive to improving production efficiency and maintaining the production environment. Utility Model Content

[0005] This application provides a raw material conveying device for concrete production, which uses a baffle buffer design to convey raw materials, thereby reducing the impact of raw material conveying and extending the service life of the equipment.

[0006] This application provides a raw material conveying device for concrete production, which adopts the following technical solution:

[0007] A raw material conveying device for concrete production includes two sets of parallel first conveyor belts, each located below a different hopper. A second conveyor belt is inclined below the first conveyor belts, with its bottom end positioned between the two sets of first conveyor belts. Raw materials fall through the first conveyor belts to the bottom end of the second conveyor belt, and are then conveyed to a mixing tank via the second conveyor belt. A support is also provided between the two sets of first conveyor belts, and a rotating rod is rotatably connected to the support. A baffle is located below the rotating rod; when the raw materials fall and impact the side of the baffle, the rotating rod rotates to buffer the impact.

[0008] By adopting the above technical solution, the present invention designs a raw material conveying device for concrete production. In use, two sets of parallel first conveyor belts located below different hoppers can respectively receive raw materials from different hoppers. The second conveyor belt, which is inclined and has its bottom end located between the two sets of first conveyor belts, can receive the raw materials falling from the first conveyor belts and convey them to the mixing tank. The rotating rod, which is rotatably connected to the support and has a baffle below, can rotate to buffer the impact when the raw materials fall and impact the side of the baffle.

[0009] Preferably, an angle limiting plate is fixedly connected to the rotating rod. The angle limiting plate rotates with the rotating rod. The bracket is provided with a groove, and the angle limiting plate is placed in the groove. The angle limiting plate is triangular, and one of its hypotenuses will abut against the top of the bracket when rotating. When it abuts completely, it will be unable to rotate, thereby limiting the maximum tilt angle of the baffle.

[0010] By adopting the above technical solution, when the raw material falls and impacts the baffle, causing the rotating rod to rotate, the angle limiting plate abuts against the top of the support to accurately limit the maximum tilt angle of the baffle, ensuring that the raw material can be guided to the second conveyor belt more stably and efficiently.

[0011] Preferably, the surface of the baffle is provided with a plurality of parallel ridges, which allow the impact force of the raw material to act more on the ridges.

[0012] By adopting the above technical solution, the impact force of the raw material is applied more to the convex strip during use, which can reduce the impact damage to the baffle as a whole, improve the service life of the baffle, and ensure the stability of the raw material conveying process.

[0013] Preferably, the rotating rod and the baffle are fixedly connected by welding.

[0014] By adopting the above technical solution, the rotating rod and the baffle are fixedly connected by welding during use, which makes the connection between the rotating rod and the baffle more secure and ensures that the two work as a whole to buffer the impact.

[0015] Preferably, the surface of the baffle is uneven, which can reduce the speed at which the raw material slides down, thereby reducing the impact force on the second conveyor belt.

[0016] By adopting the above technical solution, the uneven surface of the baffle can reduce the sliding speed of the raw material on the baffle, thereby reducing the impact of the raw material on the second conveyor belt and helping to protect the second conveyor belt.

[0017] Preferably, a scraper is also provided at the end of the first conveyor belt, and the scraper is inclined to guide the flow of raw materials.

[0018] By adopting the above technical solution, when in use, setting an inclined scraper at the end of the first conveyor belt can effectively guide the flow of raw materials, so that the raw materials fall from the first conveyor belt into the second conveyor belt in a more orderly manner.

[0019] Preferably, a drive device is provided on one side of both the first conveyor belt and the second conveyor belt.

[0020] By adopting the above technical solution, a drive device is installed on one side of both the first and second conveyor belts during use, which can provide power for the operation of the first and second conveyor belts respectively, ensuring that the concrete raw materials can fall normally from the first conveyor belt into the second conveyor belt, and then be transported to the mixing tank by the second conveyor belt.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. This utility model designs a raw material conveying device for concrete production, in which two sets of first conveyor belts are located below different hoppers, and combined with a second conveyor belt that is inclined and whose bottom end is located between the two sets of first conveyor belts, the raw material falls from the first conveyor belt into the bottom end of the second conveyor belt and is conveyed to the mixing tank, thus solving the problem of limited factory space making it difficult to transport materials to the desired location in one go.

[0023] 2. This utility model designs a raw material conveying device for concrete production. When the raw material falls and impacts the side of the baffle, it drives the rotating rod to rotate, which can buffer the impact on the second conveyor belt, reduce the impact on the service life of the conveyor belt, prevent raw material spillage, improve production efficiency and maintain the production environment.

[0024] 3. The present invention provides a raw material conveying device for concrete production, wherein the angle limiting plate on the rotating rod can limit the maximum tilt angle of the baffle, which facilitates better guidance of the raw material onto the second conveyor belt.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] This utility model discloses a raw material conveying device for concrete production, such as... Figure 1 and Figure 2 As shown, the system includes two parallel sets of first conveyor belts 1, an inclined second conveyor belt 2, a rotating rod 4 rotatably connected to a support 3, and a baffle 5 fixed below the rotating rod 4. The two sets of first conveyor belts 1 are located below different hoppers. The bottom end of the second conveyor belt 2 is located between the two sets of first conveyor belts 1 and is lower than the first conveyor belts 1. Raw materials fall from the first conveyor belt 1 into the bottom end of the second conveyor belt 2 and are then conveyed to the mixing tank. The raw materials exiting the first conveyor belt 1 impact the side of the baffle 5, causing the baffle 5 to rotate and buffer the impact on the first conveyor belt 1. This arrangement reduces the impact of the raw materials on the conveyor belt and extends its service life. Because when the raw materials impact the baffle 5, the rotation of the baffle 5 disperses and buffers the impact force, preventing the raw materials from directly impacting the conveyor belt and causing excessive damage.

[0030] Specifically, the first conveyor belt 1 includes a conveyor belt, a drive roller, and a driven roller. The conveyor belt is looped around the drive roller and driven roller. The drive roller is driven to rotate by a motor, thereby driving the conveyor belt. The conveyor belt is usually made of rubber, which has a certain degree of flexibility and wear resistance; however, other materials such as polyurethane can also be used. The surfaces of the drive roller and driven roller are usually treated with anti-slip material, such as anti-slip texture, to ensure stable transmission of the conveyor belt. The drive roller and driven roller are rotatably connected to the support 3 via bearings, and the support 3 provides support for the entire first conveyor belt 1.

[0031] Two sets of first conveyor belts 1 are arranged parallel to each other and on the same straight line, located below different hoppers. Raw materials are weighed through the hoppers and then added to the first conveyor belts 1. Each end of the first conveyor belt 1 is equipped with a scraper 9, which is inclined and typically made of metal, such as stainless steel, offering good hardness and wear resistance. The inclination angle of the scraper 9 can be adjusted according to actual needs. The scraper 9 guides the flow of the raw materials, ensuring they fall more accurately onto the second conveyor belt 2.

[0032] The second conveyor belt 2 includes an inclined conveyor belt, a drive unit, and a support structure. The conveyor belt also adopts a ring structure and is driven to rotate by the drive unit. The drive unit is typically an electric motor. The second conveyor belt 2 is inclined, with its bottom end located below and between the two sets of first conveyor belts 1. Raw materials fall from the first conveyor belts 1 to the bottom end of the second conveyor belt 2, and are then transported to the mixing tank via the second conveyor belt 2.

[0033] The rotating rod 4 is rotatably connected to the support 3 via bearings, and the baffle 5 is fixed to the rotating rod 4 by welding. An angle limiting plate 6 is fixed on the rotating rod 4. The angle limiting plate 6 is usually triangular and made of metal sheet, such as aluminum or steel plate. When the rotating rod 4 rotates, it will drive the angle limiting plate 6 to rotate, so that the angle limiting plate 6 abuts against one side of the support 3 to limit the tilt angle of the baffle 5, which facilitates better guidance of the raw materials onto the second conveyor belt 2.

[0034] Multiple parallel protrusions 8 are fixed to the surface of the baffle 5 facing the first conveyor belt 1. The protrusions 8 can be fixed to the baffle 5 by welding or integral molding. The protrusions 8 are usually made of metal, such as carbon steel, which has high strength. The protrusions 8 allow the impact force of the raw material to act more on the protrusions 8, thereby reducing the possibility of damage to the baffle 5; at the same time, the uneven surface of the baffle 5 can reduce the downward sliding speed of the raw material, thereby reducing the impact force on the second conveyor belt 2.

[0035] The implementation principle of this embodiment is as follows: During concrete production, raw materials are weighed through a hopper and added to the first conveyor belt 1. The first conveyor belt 1 transports the raw materials to the end, where they impact the side of a baffle 5. The baffle 5 rotates to buffer the impact of the raw materials on the first conveyor belt 1. Angle limiting plates 6 restrict the tilt angle of the baffle 5, allowing the raw materials to fall more effectively into the second conveyor belt 2. Raised strips 8 reduce the probability of damage to the baffle 5, and the uneven surface reduces the impact force of the raw materials on the second conveyor belt 2. This design effectively reduces the impact during raw material transportation, extends the service life of conveyor belts and other equipment, and improves the efficiency and stability of concrete production. Compared with existing technologies, it represents a significant improvement and enhancement in raw material transportation.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
