AI Technical Summary
Traditional vibrating screens and drum screens suffer severe wear and tear, are prone to clogging, and generate dust pollution during concrete aggregate screening, which can affect health.
The screening cylinder and screening mesh design driven by spiral conveyor blades achieve closed screening of concrete aggregates. The spiral conveyor blades drive the aggregates to move, and fine aggregates fall into the conveyor belt through the screening mesh, while oversized aggregates are pushed to the outlet, avoiding dust pollution from open screening.
It effectively reduces dust pollution, protects the health of operators, extends the service life of equipment, and improves screening efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete screening technology, specifically to concrete production equipment for screening materials. Background Technology
[0002] In the concrete production process, aggregate screening is a key step in ensuring the quality and performance of concrete. Traditional screening equipment usually uses vibrating screens or drum screens to classify aggregates. However, such equipment has obvious shortcomings in practical applications. Vibrating screens are prone to causing significant wear on the corresponding components and the screens are easily clogged.
[0003] The screening of concrete aggregates is usually done in an open manner, which can easily cause environmental pollution and affect the health of the operators. In order to solve the above problems, we have proposed a concrete production equipment for screening aggregates. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a concrete production equipment for screening materials, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A concrete production device for screening materials includes a screening cylinder. A rotating shaft extending into the interior of the screening cylinder is rotatably connected to the right side of the screening cylinder. Spiral conveying blades are installed on the outer ring of the rotating shaft inside the screening cylinder. Connecting plates are fixedly installed on both sides of the screening cylinder. A conveying frame is fixedly installed on the lower part of the connecting plates. A conveyor belt is installed inside the conveying frame. Screening mesh holes are opened at the bottom of the screening cylinder.
[0007] As a preferred embodiment of this utility model, the screening cylinder is L-shaped and installed at an incline, and a first drive motor is provided at the lower right part of the screening cylinder.
[0008] As a preferred embodiment of this utility model, the first drive motor is fixedly mounted on the support base by bolts, and the output end of the first drive motor is connected to the end of the rotating shaft located outside the screening cylinder.
[0009] As a preferred embodiment of this utility model, a mounting base is welded to one side of the conveying frame, and a second drive motor is fixedly mounted on the bottom surface of the mounting base by bolts.
[0010] As a preferred embodiment of this invention, the output end of the second drive motor is connected to the power shaft of the conveyor belt.
[0011] As a preferred embodiment of this utility model, brackets are fixedly installed on both sides of the conveying frame.
[0012] As a preferred embodiment of this utility model, a feed hopper is fixedly installed on the right side of the top surface of the screening cylinder.
[0013] Compared with the prior art, the present invention provides a concrete production equipment for screening materials, which has the following beneficial effects:
[0014] 1. The concrete production equipment for screening materials of this utility model is equipped with a drive motor, a spiral conveyor blade, a screening cylinder and screening mesh, etc. Concrete aggregate is fed from the feed hopper and enters the screening cylinder. The first drive motor is started, which drives the rotating shaft to rotate, thereby causing the spiral conveyor blade to rotate and moving the concrete aggregate in the screening cylinder. During the movement of the concrete aggregate, fine aggregate falls through the screening mesh onto the conveyor belt, thereby achieving the purpose of screening the concrete aggregate.
[0015] 2. The concrete production equipment for screening materials of this utility model, by setting up a screening cylinder and screening mesh, avoids the large amount of dust pollution caused by traditional open screening, thus protecting the relevant personnel. Attached Figure Description

[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. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-3 This is a concrete production equipment for screening materials. Its main body includes a screening cylinder 1. The screening cylinder 1 is made of L-shaped metal. The screening cylinder 1 is installed at an incline. The right side of the screening cylinder 1 is connected to the rotating shaft 12 through the bearing seat. The spiral conveying blades 13 are built in. Screening mesh holes 10 are evenly opened at the bottom of the cylinder body of the screening cylinder 1.
[0022] A feed hopper 3 is welded to the top right side of the screening cylinder 1. Connecting plates 2 made of steel plates are welded to both sides of the cylinder body of the screening cylinder 1, arranged symmetrically. The first drive motor 4 is fixed to the support base 5 by bolts. The output shaft of the first drive motor 4 is directly connected to the rotating shaft 12 through a coupling. The second drive motor 7 is installed on the mounting base 6 on the side of the conveyor frame 8 by bolts. The output end of the second drive motor 7 is connected to the drive roller of the conveyor belt 11. A rubber conveyor belt 11 is installed inside the conveyor frame 8. Brackets 9 are welded to both sides. The receiving position of the conveyor belt 11 is located directly below the screening mesh 10, which can transport the concrete aggregate screened through the screening mesh 10.
[0023] During the concrete production process, concrete aggregate is fed into the feed hopper 3 and enters the screening cylinder 1. The first drive motor 4 is started, which drives the rotating shaft 12 to rotate, thereby causing the spiral conveyor blades 13 to rotate and move the concrete aggregate in the screening cylinder 1.
[0024] During the movement of concrete aggregates, fine aggregates fall through the screening mesh 10 onto the conveyor belt 11, while oversized aggregates are continuously pushed by the spiral blades to the left end outlet of the screening cylinder 1 and fall into the independent collection bin. The undersized fine aggregates are conveyed by the conveyor belt 11, which can be V-shaped to prevent concrete aggregates on the conveyor belt 11 from scattering from both sides. The second drive motor 7 adjusts the belt speed according to the screening volume to prevent too much concrete aggregate from being screened, which would affect the screening of concrete aggregates by the screening cylinder 1.
[0025] This utility model uses a screening cylinder 1 to screen concrete aggregates, which avoids the large amount of dust pollution caused by traditional open screening and protects the relevant personnel.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
