Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete processing, in particular to a device for removing sundries during concrete processing. Background Art
[0002] Concrete refers to a structure or component with a certain structural strength obtained by mixing, molding, curing and hardening cement as a binder, sand and gravel as aggregates, and water in a certain proportion. In the process of concrete processing and production, in order to ensure that the concrete can meet the use requirements of the construction industry after processing, it is often necessary to remove impurities and screen the raw materials of the concrete to ensure the purity of the concrete.
[0003] The raw materials of concrete may contain large slag particles and miscellaneous materials that are not needed for processing. These miscellaneous materials may affect the processing effect. When processing concrete, it is necessary to remove the miscellaneous materials in the concrete raw materials. Some of the miscellaneous materials can be reused after processing. Generally, vibration screening is used to remove the miscellaneous materials. However, some existing concrete processing miscellaneous material removal devices only screen the concrete raw materials through a single-layer vibrating screen during the process of removing impurities and screening concrete. There is a disadvantage of poor screening effect and low screening efficiency. In the screening process, the impurities in the concrete raw materials may block the screen mouth, and there is a disadvantage that the screen is easily blocked. At the same time, the staff is required to clean the miscellaneous materials inside the screen mesh in time. If the miscellaneous materials blocking the mesh are not cleaned in time, the screening effect will be reduced, thereby affecting the subsequent processing of the concrete. Utility Model Content

The first filter plate 5 and the second filter plate 6 are both inclined, and the inclination angles of the second filter plate 6 and the first filter plate 5 are consistent with the screening shell 4. The second filter plate 6 is used to further filter the debris in the concrete raw materials to improve the screening effect. The left and right sides of the bottom side of the inner wall of the mounting frame 1 are fixedly connected with fixing frames 7. The fixing frames 7 are E-shaped and are used in conjunction with each other. The fixing frame 7 is used to install parts and support and fix the parts. A rotating mechanism 8 is arranged below one side of the fixing frame 7. The rotating mechanism 8 is used to control the upper parts to move up and down. A moving rod 9 is slidably connected to the inside of the extended side of the fixing frame 7. The number of the moving rods 9 is consistent with the number of the fixing frames 7. The top of the moving rod 9 is movably connected to the bottom of the screening shell 4. The moving rod 9 is used to control the upper parts to move up and down to vibrate and generate a stable vibration frequency. A connecting belt 10 is hinged at the bottom of the moving rod 9. The shape of the connecting belt 10 is O-shaped. The number of the connecting belts 10 is consistent with that of the moving rods 9. The connecting belt 10 is movably connected to the parts of the rotating mechanism 8. The connecting belt 10 is used to connect the parts so that multiple parts are linked and the rotating mechanism 8 cooperates with the connecting belt 10 to control the moving rod 9 to move up and down reciprocatingly to generate vibration, and the parts on the top of the moving rod 9 are controlled to shake by the same vibration frequency. Moving grooves 11 are opened on both sides of the screening shell 4. The number of moving grooves 11 is four and they are symmetrically distributed on one side.

Both sides of the screening shell 4 are fixedly connected with guide rods 14. There are four guide rods 14 and they are used in pairs.

[0024] The rotating mechanism 8 includes a rotating motor 81 installed below a fixed frame 7 on one side, a linkage assembly 82 is installed on one side of the output shaft of the rotating motor 81, and the linkage assembly 82 is composed of a driving belt pulley, a linkage belt and a driven belt pulley.

When screening the concrete raw materials, When the rotating motor 81 cooperates with the linkage assembly 82, the connecting shafts 83 on both sides are synchronously controlled to rotate, and the turntable 84 is driven to rotate by the connecting shaft 83. While the turntable 84 rotates, the positioning rod 85 is controlled to pull the connecting belt 10. By changing the position of the positioning rod 85 when it rotates and cooperating with the connecting belt 10, the moving rod 9 is controlled to push the screening shell 4 on its top to move up and down reciprocatingly for vibration, so as to remove the debris from the concrete raw materials inside the screening shell 4, and at the same time control the concrete raw materials to move to one side. Through the setting of the two sets of rotating mechanisms 8, the stability during vibration is improved, and the screening effect of the concrete raw materials is improved. In the process of the concrete raw materials sliding to one side, the concrete raw materials are quickly dispersed on the surface of the first filter plate 5 and the second filter plate 6, so that the concrete can fall from the mesh more smoothly, thereby achieving the purpose of improving the screening effect.
[0025] The moving mechanism 12 includes a stepper motor 121 installed on one side of the opening of the screening shell 4, and a reciprocating threaded rod 122 is fixedly connected to one side of the output shaft of the stepper motor 121.

The moving block 123 is slidably connected to the screening shell 4, and the guide rod 14 penetrates the moving block 123 and is slidably connected to the moving block 123. While screening the concrete raw materials, the reciprocating threaded rod 122 is controlled to rotate by the stepper motor 121, driving the moving block 123 and the two groups of dredging mechanisms 13 on one side to reciprocate, and dredge the meshes of the first filter plate 5 and the second filter plate 6. By driving the dredging mechanism 13 to move back and forth, the dredging efficiency is improved without affecting the screening.
[0026] The dredging mechanism 13 includes a moving shell 131 fixed to one side of the moving block 123, and there are two moving shells 131. The upper moving shell 131 is located below the first filter plate 5, and the lower moving shell 131 is located below the second filter plate 6. The moving shell 131 is slidably connected to the inner wall of the screening shell 4. A positioning groove 132 is provided on the top of the moving shell 131. The number of the positioning grooves 132 is consistent with the number of meshes of the transverse axis of the first filter plate 5 and the second filter plate 6, respectively. A compression spring 133 is fixedly connected to the bottom of the inner wall of the positioning groove 132, and a push rod 134 is fixedly connected to the top of the compression spring 133. The push rod 134 is slidably connected to the inner wall of the positioning groove 132, and the top of the push rod 134 is movably connected to the bottom of the first filter plate 5 and the second filter plate 6 and the inner wall of the mesh. The diameter of the rod 134 is smaller than the diameter of the mesh of the first filter plate 5, the diameter of the lower push rod 134 is smaller than the diameter of the mesh of the second filter plate 6, and the diameters of the push rods 134 at the upper and lower positions are inconsistent. The two groups of dredging mechanisms 13 are controlled by the moving mechanism 12 to move back and forth. While moving, under the action of the compression spring 133, the top of the push rod 134 is always in contact with the bottom of the first filter plate 5 or the second filter plate 6. When moving to the mesh of the first filter plate 5 and the second filter plate 6, the push rod 134 is driven by the elastic force of the compression spring 133 itself to enter the mesh of the first filter plate 5 and the second filter plate 6, and the concrete slag and stone raw materials in the mesh are pushed out to avoid the concrete slag and stone raw materials getting stuck in the mesh and causing the mesh to be blocked, thereby affecting the screening effect of the concrete raw materials.
[0027] Working principle: first, turn on the rotating motor 81 and the stepper motor 121, then feed the concrete raw material into the interior of the screening shell 4 through the feed hopper 2, and control the connecting shafts 83 on both sides to rotate simultaneously through the rotating motor 81 and the linkage assembly 82, and drive the turntable 84 to rotate through the connecting shaft 83. While the turntable 84 rotates, the positioning rod 85 is controlled to pull the connecting belt 10, so as to control the moving rod 9 to move up and down and push the screening shell 4 on its top to vibrate, and while vibrating, the concrete raw material is screened through the first filter plate 5 and the second filter plate 6 to remove the sundries in the concrete raw material, and at the same time, the concrete raw material is controlled to move to one side, and while screening, the reciprocating threaded rod 122 is controlled to rotate by the stepper motor 121, and the moving block 123 is controlled by the reciprocating threaded rod 122 to drive the two groups of dredging mechanisms 13 to move back and forth, so as to push out the concrete raw material blocked in the mesh of the first filter plate 5 and the second filter plate 6, so as to avoid the mesh blockage affecting the screening effect, and in the process of removing the sundries, the screened sundries and the usable raw materials can be collected separately.
