Description

Technical Field

[0001] This utility model relates to the field of recycled aggregate sorting technology, and in particular to a modular recycled aggregate sorting vibrating screen mechanism. Background Technology

[0002] Recycled aggregate sorting technology is a core link in the resource utilization of construction waste. It involves screening and classifying recycled aggregates such as crushed waste concrete and bricks, thereby enabling the collection of recycled aggregates of different volumes after crushing.

[0003] Existing vibrating screen mechanisms for sorting recycled aggregates are generally integrated or fixed with fasteners such as bolts. The screening work is carried out by a vibrating motor. The operation is not convenient when the screening components need to be replaced, which makes it impossible to flexibly change the operation according to the type of recycled aggregate and the screening requirements.

[0004] Therefore, the existing vibrating screen mechanism for sorting recycled aggregates is not convenient to replace when the screening components need to be replaced. This utility model can slide the screening plate through the combined groove, and fix its position by sliding the limiting block on the square rod into the connecting groove on the screening plate. The overall assembly is convenient and fast, and it is also convenient for the subsequent disassembly and replacement of the screening plate. Utility Model Content

[0005] To overcome the problem that common modular recycled aggregate sorting vibrating screen mechanisms are not convenient to operate when the screening components need to be replaced.

[0006] The technical solution of this utility model is as follows: a modular recycled aggregate sorting vibrating screen mechanism, including a base plate and a drive motor. A support frame is fixedly installed on the top side of the base plate, and a combination groove is opened on both sides of the inner wall of the support frame. A drive motor is fixedly installed at the top rear end of the support frame, and a cam body is embedded and fixedly installed at the front end of the drive motor. A screening plate is installed inside the support frame, and the frame of the screening plate is located inside the combination groove. A connecting groove and a limiting groove are opened in the middle of the rear end of the screening plate. A combination square frame is fixedly installed on the top surface of the base plate.

[0007] Preferably, the screening plate has a porous structure, and the screening plate is connected to the combined groove by a sliding connection. The combined groove is inclined on the inner wall of the supporting frame, and the aperture size of the screening plate decreases from top to bottom.

[0008] Preferably, a spring is installed at the center of the combined frame, and a square rod is welded and fixedly installed at the top of the spring. The square rod passes through the top surface of the combined frame and penetrates the screening plate. A collision plate and a limiting block are provided on the outer side of the square rod. The collision plate is located below the screening plate, and the limiting block penetrates the connecting groove. A pressure block is provided on the front surface of the top of the square rod, and a positioning frame is provided below the pressure block. The positioning frame is connected through the square rod and is fixedly installed on the inner side of the rear end frame of the supporting frame.

[0009] Preferably, the square rod is telescopically connected to the combined square frame via a spring, and the square rod, the impact plate, and the limiting block are integrated into a single structure. The top surface of the impact plate is inclined, and the top surface of the impact plate abuts against the bottom surface of the screening plate.

[0010] Preferably, the square rod has impact plates and limiting blocks evenly distributed on it, and the square rod is connected to the connecting groove by a sliding connection, and the limiting block is connected to the limiting groove by a sliding engagement, and the height of the limiting block is greater than the thickness of the screening plate.

[0011] Preferably, the top two sides of the square rod are chamfered, and there is a gap between the top surface of the square rod and the curved surface of the cam body frame.

[0012] Preferably, the square rod is connected to the positioning frame by a sliding connection, and the square rod is connected to the pressure block by welding. Furthermore, the distance between the pressure block and the positioning frame is greater than the height of the limiting block.

[0013] The beneficial effects of this utility model are:

[0014] 1. The screening plate can be slid into the inside of the support frame through the combination groove while maintaining an inclination. The screening plate is assembled and fixed with the square rod and the limiting block according to the connecting groove and the limiting groove. The assembly is convenient and quick, and it is convenient to replace the screening plate in the future.

[0015] 2. The cam body pushes the square rod, which causes the square rod to repeatedly extend and retract through the combination of the square frame, spring and positioning frame, thereby driving the impact plate body and the limiting block to extend and retract. This facilitates the impact plate body to collide with the screening plate to generate vibration, thereby achieving sorting, without affecting the positioning of the screening plate.

[0016] 3. When assembling the screening plate, the square rod can be pressed down by the pressure block to facilitate the connection groove on the screening plate to pass through the square rod, so that the limiting groove and the limiting block are aligned, which facilitates the assembly operation. The pressure block also facilitates the pressing operation. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a modular recycled aggregate sorting vibrating screen mechanism, including a base plate 1 and a drive motor 4. A support frame 2 is fixedly installed on the top side of the base plate 1, and a combination groove 3 is opened on both sides of the inner wall of the support frame 2. The drive motor 4 is fixedly installed at the top rear end of the support frame 2, and a cam body 5 is embedded and fixedly installed at the front end of the drive motor 4. A screening plate 6 is installed inside the support frame 2, and the frame of the screening plate 6 is located inside the combination groove 3. A connecting groove 7 and a limiting groove 8 are opened in the middle of the rear end of the screening plate 6. A combination square frame 9 is fixedly installed on the top surface of the base plate 1.

[0026] The screening plate 6 has a porous structure, and the connection between the screening plate 6 and the combined groove 3 is a sliding connection. The combined groove 3 is inclined on the inner wall of the supporting frame 2. The aperture size of the screening plate 6 decreases from top to bottom, which facilitates the inclined installation of the screening plate 6. At the same time, the distribution of the screening plate 6 is conducive to the subsequent screening and sorting of recycled aggregates.

[0027] A spring 10 is installed at the center of the combined frame 9, and a square rod 11 is welded and fixed to the top of the spring 10. The square rod 11 passes through the top surface of the combined frame 9 and penetrates the screening plate 6. A collision plate 12 and a limiting block 13 are provided on the outside of the square rod 11. The collision plate 12 is located below the screening plate 6, and the limiting block 13 passes through the connecting groove 7. A pressure block 14 is provided on the front surface of the top of the square rod 11, and a positioning frame 15 is provided below the pressure block 14. The positioning frame 15 is connected to the square rod 11 and is fixedly installed. Inside the rear frame of the supporting frame 2, the square rod 11 forms a telescopic structure with the combined square frame 9 via the spring 10. The square rod 11, the impact plate body 12, and the limiting block 13 are integrated into one structure. The top surface of the impact plate body 12 is inclined, and the top surface of the impact plate body 12 is in contact with the bottom surface of the screening plate 6. This allows the square rod 11 to drive the impact plate body 12 and the limiting block 13 to telescopically move. According to the movement of the impact plate body 12, the impact plate body 12 can separate from the screening plate 6 and then collide, achieving vibration operation and thus screening.

[0028] The square rod 11 has impact plates 12 and limiting blocks 13 evenly distributed on it. The square rod 11 is connected to the connecting groove 7 by sliding connection, and the limiting block 13 is connected to the limiting groove 8 by sliding engagement. The height of the limiting block 13 is greater than the thickness of the screening plate 6. During the assembly process, the screening plate 6 is combined with the limiting block 13 on the square rod 11 through the connecting groove 7 and the limiting groove 8, which is convenient for installation and facilitates subsequent disassembly and replacement.

[0029] The top two sides of the square rod 11 are chamfered, and there is a gap between the top surface of the square rod 11 and the curved surface of the cam body 5. The chamfer on the square rod 11 facilitates the subsequent extension and retraction operation under the pressure of the cam body 5. At the same time, the gap between the square rod 11 and the cam body 5 is conducive to the subsequent collision operation between the impact plate 12 and the screening plate 6.

[0030] The square rod 11 is connected to the positioning frame 15 by sliding connection, and the square rod 11 is connected to the pressure block 14 by welding fixation. The distance between the pressure block 14 and the positioning frame 15 is greater than the height of the limiting block 13, which allows the square rod 11 to be further stabilized by the positioning frame 15. The pressure block 14 on the square rod 11 facilitates the pressing operation of the square rod 11 and the adjustment operation during the assembly process.

[0031] Working principle: According to Figures 1-6First, after placing the base plate 1 and the support frame 2 in a suitable position, the screening plate 6 is slid into the support frame 2 through the combination groove 3 for assembly. At the same time, the pressure block 14 presses down on the square rod 11, causing the square rod 11 to slide up and down the positioning frame 15. Simultaneously, the square rod 11 pushes the spring 10 in the combination frame 9 to retract and rotate. The square rod 11 also drives the impact plate body 12 and the limiting block 13 to press down, so that the screening plate 6 drives the connecting groove 7 to slide and connect with the square rod 11. After the square rod 11 slides into the limiting groove 8, the limiting block 13 on the square rod 11 aligns with the limiting groove 8. Then, the pressure block 14 is released, and the square rod 11 is pushed upward and slid back to its original position by the elastic force of the spring 10. The square rod 11 drives the impact plate body 12 and the limiting block 13 to rise. The limiting block 13 passes through the limiting groove 8 for positioning and assembly, maintaining the stability of the screening plate 6 after installation. At the same time, the top surface of the impact plate body 12 and the bottom surface of the screening plate 6 are fitted and abutted together.

[0032] according to Figures 1-2 and Figures 5-6 Subsequently, the drive motor 4 can be connected to an external power source via a power cord and started. The drive motor 4 can drive the cam body 5 to rotate. The cam body 5 can slide down by pressing the square rod 11 through the protrusion, so that the square rod 11 drives the impact plate body 12 and the limiting block 13 to perform slight extension and retraction. When the protrusion of the cam body 5 separates from the square rod 11, the square rod 11 pushes the impact plate body 12 to collide with the bottom surface of the screening plate 6 through the elastic force of the spring 10, thereby generating vibration, which facilitates the screening and sorting of recycled aggregate on the screening plate 6. The drive motor 4 is a known and existing technology in the market, and will not be described in detail here.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
