Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a feeding structure for a concrete production line. Background Technology

[0002] Concrete, as one of the most widely used basic materials in modern construction engineering, requires high efficiency and quality control in its production process. In a concrete production line, the feeding structure is the first step in the entire production process, mainly responsible for accurately and efficiently conveying raw materials such as cement, aggregates (sand, stone), water, and admixtures to the mixing host for mixing according to a preset ratio.

[0003] The patent with publication number CN216442819U discloses a feeding structure for a concrete production line, including a feeding conveyor belt, two front-end supports at the front end of the feeding conveyor belt, and two rear-end supports at the rear end of the feeding conveyor belt. Connecting blocks are fixedly connected to the inner sides of the two rear-end supports. A fixed sleeve is provided between the two connecting blocks. A connecting sleeve is fixedly connected to the fixed sleeve by four fixed bolts. A rotating sleeve is rotatably connected to one side of the connecting sleeve. The rotating sleeve has an internal thread. A threaded rod is threadedly connected to the rotating sleeve through the internal thread. A movable ring is hinged to one end of the threaded rod, and the inside of the movable ring is sleeved with the outer surface of the fixed column. Both ends of the fixed column are fixedly connected to the bottom of the guide plate. The two sides of the guide plate are rotatably connected to the outer sides of the two rear-end supports through two connecting pieces.

[0004] However, the above-mentioned device has the following problems when in use: When in use, the device can only continuously convey one type of material at a time. This working mode will cause different materials (such as aggregates, cement, admixtures, etc.) to separate in time and space, resulting in obvious stratification and accumulation during the unloading process, rather than uniform premixing. This initial uneven distribution will greatly increase the time required for subsequent mixing and make it difficult to achieve the ideal uniformity. Ultimately, this will lead to problems such as poor homogeneity and unstable strength of the concrete mixture, which will seriously restrict the efficiency and quality of concrete production. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a feeding structure for a concrete production line, which effectively improves the quality and efficiency of concrete production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding structure for a concrete production line includes a fixed support, an mounting platform fixedly installed on the fixed support, a first conveyor belt and a second conveyor belt set on the mounting platform, an mounting block fixedly installed on the fixed support, a mixing chamber set on the mounting block, a discharge port fixedly installed at the bottom of the mixing chamber, the mixing chamber being located directly below the higher ends of the first and second conveyor belts, a guiding mixing mechanism being set inside the mixing chamber, and two sets of cleaning mechanisms being set on the mounting platform.

[0008] Preferably, the guiding mixing mechanism includes a first inclined plate and a second inclined plate, both of which are installed at an incline. The first inclined plate is adapted to the first conveyor belt, and the second inclined plate is adapted to the second conveyor belt. The lower end of the first inclined plate is located above the discharge port, and the lower end of the second inclined plate is located above the first inclined plate.

[0009] Preferably, a vibration motor is embedded in the bottom of the mixing chamber.

[0010] Preferably, the cleaning mechanism includes a fixed plate, which is detachably fixed to the mounting platform by bolts. A lifting plate is slidably installed inside the fixed plate. A brush body is embedded in the side of the lifting plate away from the fixed plate and directly abuts against the surface of the first or second conveyor belt. Return springs are equidistantly installed on the side of the lifting plate facing the fixed plate, and the other end of the return spring is fixedly installed on the inner wall of the fixed plate.

[0011] Preferably, a mounting bracket is fixedly installed on the fixed support, a storage box is fixedly installed on the mounting bracket, a discharge pipe is embedded in the side of the storage box facing the mixing chamber, the discharge pipe is located above the discharge port, and an electric control valve is installed on the discharge pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, materials are fed from the first and second conveyor belts respectively, and guided by the first and second inclined plates installed at different heights and at an angle, forming two material flows under the action of gravity. The material flow on the second conveyor belt can directly impact and merge with the material flow on the first conveyor belt. This collision and impact achieves sufficient preliminary mixing before falling into the main mixing equipment, significantly improving the uniformity of material blending, effectively avoiding powder agglomeration or aggregate segregation, and greatly reducing the workload of the subsequent main mixing equipment. Thus, while improving the final concrete quality, it reduces the overall energy consumption and time cost of production. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 A feeding structure for a concrete production line includes a fixed support 1, an mounting platform 2 fixedly installed on the fixed support 1, and a first conveyor belt 3 and a second conveyor belt 4 provided on the mounting platform 2. The first conveyor belt 3 and the second conveyor belt 4 are used to simultaneously transport different materials to facilitate subsequent mixing activities.

[0022] Preferably, the running speeds of the first conveyor belt 3 and the second conveyor belt 4 can be adjusted separately by controlling the frequency converter or mechanical speed regulating device of the motor, thereby accurately controlling the feeding ratio of various materials and adapting to the concrete production needs of different mix proportions. Since this is existing technology, it will not be described in detail here.

[0023] A mounting block 5 is fixedly installed on the fixed bracket 1. A mixing chamber 6 is provided on the mounting block 5. A discharge port 11 is fixedly installed at the bottom of the mixing chamber 6. The mixing chamber 6 is located directly below the higher end of the first conveyor belt 3 and the second conveyor belt 4. A guiding mixing mechanism is provided inside the mixing chamber 6.

[0024] The mixing chamber 6 is securely connected to the fixed bracket 1 via mounting block 5. Located below the discharge ends of the two conveyor belts, it receives materials. After entering the mixing chamber 6, the materials undergo preliminary mixing via an internal guiding mixing mechanism, preparing for thorough mixing. The discharge port 11 discharges the pre-mixed materials to the next process.

[0025] The mounting platform 2 is equipped with two sets of cleaning mechanisms, which correspond to the first conveyor belt 3 and the second conveyor belt 4 respectively. These mechanisms can remove residual materials adhering to the belt surface during operation, preventing accumulation that could affect equipment operation.

[0026] like Figure 4 As shown, the guiding mixing mechanism includes a first inclined plate 12 and a second inclined plate 13. Both the first inclined plate 12 and the second inclined plate 13 are installed at an inclination. The first inclined plate 12 is adapted to the first conveyor belt 3, and the second inclined plate 13 is adapted to the second conveyor belt 4. The lower end of the first inclined plate 12 is above the discharge port 11, and the lower end of the second inclined plate 13 is above the first inclined plate 12.

[0027] Material on the first conveyor belt 3 falls onto the first inclined plate 12 and descends under gravity. Material on the second conveyor belt 4 falls onto the second inclined plate 13 and descends under gravity. At the end of the second inclined plate 13, the material on the second inclined plate 13 can fall directly onto the first inclined plate 12 and mix with the material on the first inclined plate 12. Then, both fall together into the production equipment through the discharge port 11.

[0028] like Figure 4 As shown, a vibration motor 14 is embedded in the bottom of the mixing chamber 6. The vibration motor 14 can generate high-frequency micro-amplitude vibration during operation to prevent materials from sticking or accumulating on the inner wall or inclined plate surface of the mixing chamber 6, ensuring that the materials slide smoothly to the discharge port 11 and avoiding blockage.

[0029] like Figure 5 As shown, the cleaning mechanism includes a fixed plate 15, which is detachably fixed to the mounting platform 2 by bolts. A lifting plate 17 is slidably installed inside the fixed plate 15. A brush body 16 is embedded in the side of the lifting plate 17 away from the fixed plate 15. The brush body 16 directly abuts against the surface of the first conveyor belt 3 or the second conveyor belt 4. Return springs 18 are equidistantly installed on the side of the lifting plate 17 facing the fixed plate 15. The other end of the return spring 18 is fixedly installed on the inner wall of the fixed plate 15.

[0030] The brush body 16 is made of wear-resistant material and is adjustable via the lifting plate 17 to compensate for the height loss caused by wear of the brush body 16, ensuring that it is always in contact with the surface of the first conveyor belt 3 or the second conveyor belt 4.

[0031] The mounting plate 15 is installed by bolts, which facilitates disassembly, replacement, or maintenance of cleaning components.

[0032] like Figure 1 , Figure 2 As shown, a mounting bracket 7 is fixedly installed on the fixed bracket 1, and a storage box 8 is fixedly installed on the mounting bracket 7. A discharge pipe 9 is embedded in the side of the storage box 8 facing the mixing chamber 6. The discharge pipe 9 is located above the discharge port 11, and an electric control valve 10 is provided on the discharge pipe 9 to facilitate synchronous addition and ensure the mixing effect.

[0033] The storage tank 8 is securely mounted above the mixing chamber 6 via the mounting bracket 7, with its discharge pipe 9 outlet facing the discharge port 11. Through the precise control of the electric control valve 10, small doses of additives are accurately and timely discharged from the discharge pipe 9, falling directly into the main material flow that is falling from the discharge port 11 after preliminary mixing. This achieves immediate and uniform contact and mixing of the additives and the main material before entering the next stage of equipment, effectively ensuring the uniform distribution of the admixture and the final mixing quality of the concrete.

[0034] The equipment controls the opening and closing of the electrically controlled valve 10 through the control system. Since this is existing technology, it will not be described in detail here.

[0035] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
