Description

Technical Field

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

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and, if necessary, admixtures and additives in a certain proportion, followed by uniform mixing, compaction, and curing. It is widely used in construction engineering.

[0003] In the concrete production process, powdery materials such as cement and fly ash are important components and need to be transported to the mixing equipment through a specific feeding mechanism to ensure the concrete mix proportions and performance.

[0004] Existing equipment used for conveying these powdery materials, such as screw conveyors, often faces clogging problems in actual use. This is because powdery materials are easily affected by air humidity and adhere to the inner wall of the conveying pipe. Roughness of the inner wall or clumps of residual material can exacerbate this adhesion, leading to gradual accumulation of material.

[0005] If the material has excessive moisture content and forms damp lumps, it will also produce hard lumps that can jam the spiral blades or block the discharge port. This not only requires the machine to be stopped for cleaning, but also seriously affects the continuity and efficiency of concrete production.

[0006] Therefore, the inventors believe that designing a feeding mechanism for concrete production that can effectively solve the clogging problem in the feeding process of powdery materials in concrete production has become a technical challenge that needs to be overcome.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-4 To address the problems mentioned in the background section, this utility model provides a feeding mechanism for concrete production to solve the aforementioned technical problems. The technical solution is as follows:

[0029] A feeding mechanism for concrete production includes: a column 100, a connecting seat, a discharge bin 140, a feeding hopper 150, a motor 160, a discharge pipe 170, and a feeding unit;

[0030] The connecting seat is fixed on the column 100; the feeding hopper 140 is fixed on the connecting seat;

[0031] The feeding hopper 140 is conical, and a sealing cover 141 is fixed to the top of the feeding hopper 140; the feeding hopper 150 is fixed on the sealing cover 141, and the discharge port at the bottom of the feeding hopper 150 is connected to the feeding hopper 140.

[0032] The feeding pipe 170 is fixed to the feeding port of the feeding bin 140;

[0033] The feeding unit includes a stirring shaft 180 and an auger shaft 120 fixed coaxially with the stirring shaft 180;

[0034] The stirring shaft 180 is located in the feeding bin 140, the upper half of the auger shaft 120 is located in the feeding bin 140, and the lower half of the auger shaft 120 is located in the feeding pipe 170.

[0035] Stirring blades 181 are spaced apart on the stirring shaft 180, and spiral blades 121 are provided on the auger shaft 120;

[0036] The motor 160 is fixed on the sealing cover 141, and the main shaft of the motor 160 is fixedly connected to the stirring shaft 180.

[0037] In this embodiment, the connecting seat includes a fixed seat 111, a slider 112, and a cylinder 114;

[0038] The fixing base 111 is fixed to the column 100; the fixing base 111 is provided with a vertical slide rail;

[0039] The slider 112 is slidably connected to the vertical slide rail; the feeding bin 140 is fixed to the slider 112;

[0040] A lateral fixing block 113 is provided at the bottom of the fixed base 111, and the cylinder 114 is fixed on the lateral fixing block 113; the driving end of the cylinder 114 is fixedly connected to the bottom of the slider 112.

[0041] It should be noted that the structural design of the above-mentioned connecting seat can facilitate the adjustment of the height of the feeding hopper 140 to adapt to different working conditions.

[0042] In this embodiment, the shaft diameter of the auger shaft 120 is smaller than the shaft diameter of the stirring shaft 180; the inner diameter of the feed pipe 170 is smaller than the shaft diameter of the stirring shaft 180.

[0043] It should be noted that the auger shaft 120 has a smaller diameter, which increases the gap between the spiral blades and the pipe wall and reduces the adhesion caused by material extrusion and friction; the inner diameter of the feed pipe 170 is larger than that of the auger shaft but smaller than that of the mixing shaft, which ensures that the conveying section is compact to prevent material stagnation, while allowing the mixing shaft to be thicker to enhance the crushing capacity.

[0044] The working method of a concrete feeding mechanism provided in this embodiment of the utility model is as follows:

[0045] (1) When working, first put the powdery materials such as cement and fly ash into the feeding hopper 150. The materials enter the discharge bin 140 through the discharge port at the bottom of the feeding hopper 150. At this time, start the motor 160. The main shaft of the motor 160 drives the stirring shaft 180 and the auger shaft 120 fixed on the same axis to rotate synchronously.

[0046] (2) The stirring shaft 180 is located in the feeding bin 140. The stirring blades 181 arranged at intervals on it rotate with the shaft to stir the powdery material entering the feeding bin 140. This can effectively break up any possible lumps and prevent the material from forming hard lumps.

[0047] (3) The upper half of the auger shaft 120 is located in the feeding bin 140 and the lower half is located in the feeding pipe 170. During the rotation of the auger shaft 120, the spiral blades 121 gradually push the stirred material from the feeding bin 140 to the feeding pipe 170.

[0048] Because the shaft diameter of the auger shaft 120 is smaller than that of the mixing shaft 180, and the inner diameter of the feed pipe 170 is smaller than that of the mixing shaft 180, the material can enter the feed pipe 170 more smoothly during the pushing process, reducing stagnation.

[0049] (4) Finally, the material is transported to the mixing equipment through the feeding pipe 170 to complete the feeding process. During the entire process, the sealing cover 141 on the top of the feeding hopper 140 plays a sealing role, reducing the impact of external factors on the material in the hopper and ensuring the stable progress of the feeding work.

[0050] The present invention provides a concrete production feeding mechanism with the following advantages: The present invention adopts an integrated design of mixing and conveying: the mixing shaft and mixing blades in the feeding hopper can break up lumpy materials and prevent lumps from entering the conveying section; the upper and lower sections of the auger shaft are located in the feeding hopper and the feeding pipe respectively, and the spiral blades continuously push the material to avoid static accumulation. The two work together to destroy the blockage conditions from the source.
