Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a concrete recycled aggregate sorting device. Background Technology

[0002] In today's rapidly developing construction industry, a large amount of concrete waste is constantly being generated, placing a heavy burden on the environment. At the same time, natural aggregate resources are becoming increasingly scarce. Therefore, the application of concrete recycled aggregate sorting devices is particularly important. It can not only effectively process waste concrete, achieving resource recycling and alleviating the shortage of natural aggregates, but also reduce environmental pollution, aligning with the concept of sustainable development.

[0003] In existing technologies, relatively simple vibrating screening machines are commonly used for sorting recycled concrete aggregates. These devices typically rely on a motor to drive the screen body to vibrate. By utilizing the up-and-down or left-and-right swaying of the screen body, waste concrete is forced through the screen under gravity, thereby separating aggregates of different particle sizes. The principle is mainly based on the vibration causing the aggregates to move on the screen, and the difference in screen aperture size is used to screen out aggregate particles of different sizes.

[0004] However, due to the relatively simple vibration mode and the short relative movement distance between the waste concrete and the screen, some aggregates cannot fully contact the screen and be separated through the screen with a suitable aperture, resulting in low screening efficiency and difficulty in ensuring the accuracy of the screening effect. Therefore, a concrete recycled aggregate sorting device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete recycled aggregate sorting device, which aims to improve the problem that the existing technology, which only uses vibration, results in a short relative movement distance between waste concrete and the screen.

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

[0007] A concrete recycled aggregate sorting device includes a sorting device body, a vibration component is installed inside the sorting device body, a sorting frame is slidably connected inside the sorting device body, and a fixing component is installed inside the sorting frame.

[0008] The vibration assembly includes an eccentric wheel, the sidewall of which is rotatably connected to the inside of the sorting device body. A rotating wheel is rotatably connected to the sidewall of the sorting device body, and the rotating wheel is connected to the eccentric wheel. A connecting belt is rotatably connected between the rotating wheels. A motor is installed on one sidewall of the rotating wheel, and the output end of the motor is connected to the rotating wheel.

In this utility model, the starting motor drives the bottom rotating wheel to rotate, and through the connecting belt, the upper rotating wheel rotates synchronously, driving the eccentric wheel to rotate and strike the sorting frame.

[0034] 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.

[0035] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a concrete recycled aggregate sorting device, comprising a sorting device body 1, a vibration component inside the sorting device body 1, a sorting frame 2 slidably connected inside the sorting device body 1, and a fixing component inside the sorting frame 2; the vibration component includes an eccentric wheel 3, which generates a striking force to move the sorting frame 2 up and down; the side wall of the eccentric wheel 3 is rotatably connected inside the sorting device body 1; a rotating wheel 4 is rotatably connected to the side wall of the sorting device body 1, and the rotating wheel 4 is connected to the eccentric wheel 3; a connecting belt 5 is rotatably connected between the rotating wheels 4, and the connecting belt 5 is used to connect the bottom. The sorting device body 1 has a square groove 7 inside and a fixed rod 9 inside. The side wall of the fixed rod 9 is fixedly connected to the square groove 7. The side wall of the fixed rod 9 is slidably connected to the slider 8. The side wall of the fixed rod 9 is sleeved with a first spring 10. One end of the first spring 10 is fixedly connected to the side wall of the slider 8, and the other end of the first spring 10 is fixedly connected to the square groove 7. The side wall of the sorting frame 2 is fixedly connected to a connecting rod 11. The side wall of the connecting rod 11 is fixedly connected to the side wall of the slider 8.

[0036] Waste concrete is poured into the sorting device body 1, and the motor 6 is started. The operation of the motor 6 drives the bottom rotating wheel 4 to rotate. The bottom rotating wheel 4 is connected to the upper rotating wheel 4 through the connecting belt 5. Under the transmission action of the connecting belt 5, the upper rotating wheel 4 can rotate synchronously. As the rotating wheel 4 rotates, the eccentric wheel 3 also rotates. During the rotation, the eccentric wheel 3 changes its contact position with the sorting frame 2, thereby generating an impact force, causing the sorting frame 2 to move up and down. When the sorting frame 2 moves up and down, the slider 8 will slide along the side wall of the fixed rod 9. The fixed rod 9 plays a guiding role, ensuring that the slider 8 can only move in one direction. As the slider 8 moves upward, it compresses the first spring 10. The first spring 10 is elastic and stores elastic potential energy when compressed. When the striking force of the eccentric wheel 3 changes, the first spring 10 releases its elastic potential energy, assisting the sorting frame 2 in reciprocating up and down vibration. This vibration causes the waste concrete to shake up and down within the sorting frame 2. During this process, waste concrete particles of different sizes are separated and discharged by screens 12 with different apertures. In this way, the waste concrete is graded and screened, providing raw materials of different particle sizes for subsequent processing, which is convenient for subsequent processing.

[0037] Reference Figure 4 - Figure 6 The fixing assembly includes a screen 12 for separating waste concrete particles of different sizes. A fixing plate 13 is fixedly connected to the side wall of the screen 12. The side wall of the fixing plate 13 is slidably connected inside the sorting frame 2. A screw 14 is installed inside the sorting frame 2. A rotating block 15 is threadedly connected to the side wall of the screw 14. A lever 16 is fixedly connected to the side wall of the rotating block 15. A connecting post 17 is slidably connected inside the screw 14. A pull ring 18 is fixedly connected to the side wall of the connecting post 17. A connecting block 19 is fixedly connected to the side wall of the connecting post 17. The side wall of the connecting block 19 slides inside the screw 14. A locking post 20 is rotatably connected to the side wall of block 19. The locking post 20 is used to abut against the side wall of sorting frame 2 to fix the fixing plate 13. A locking block 21 is fixedly connected to the lower surface of screw 14. A vertical groove 22 is opened inside the locking block 21. A fixing post 23 is fixedly connected to one end of connecting post 17. A second spring 24 is sleeved on the side wall of fixing post 23. One end of the second spring 24 is fixedly connected to the side wall of connecting post 17. The other end of the second spring 24 is fixedly connected to the inside of vertical groove 22. One end of connecting post 17 is slidably connected to the inside of locking block 21. The side wall of fixing post 23 is slidably connected to the inside of vertical groove 22.

[0038] During the installation of the screen 12, first insert the fixing plate 13 into the sorting frame 2, then press the pull ring 18, which is connected to the connecting post 17. Pressing the pull ring 18 will cause the connecting post 17 to move downwards. When the connecting post 17 moves downwards, it will apply pressure to the second spring 24, causing the second spring 24 to contract and store elastic potential energy. As the connecting post 17 moves, the connecting block 19 enters the interior of the locking block 21, and at the same time, the locking post 20 rotates and fits into the interior of the screw 14. At this time, after inserting the screw 14 into the interior of the sorting frame 2, release the connecting post 17, and the second spring 24 will rebound and release. The stored elastic potential energy causes the connecting block 19 to disengage from the locking block 21, thereby causing the locking post 20 to rotate and open, and abut against the side wall of the sorting frame 2. Then, by rotating the lever 16, which is connected to the rotating block 15, the lever 16 can drive the rotating block 15 to rotate to the surface of the sorting frame 2. After the rotating block 15 rotates to the surface of the sorting frame 2, it will form a fastening force on the fixing plate 13, fixing the fixing plate 13 to the side wall of the sorting frame 2, thereby completing the installation of the screen 12, ensuring that the screen 12 remains stable during the vibrating screening process, without displacement or falling off, and ensuring the normal operation of the screening work.

[0039] Working principle: Waste concrete is poured into the body 1 of the sorting device. The motor 6 is started to drive the bottom wheel 4 to rotate. Under the transmission action of the connecting belt 5, the upper wheel 4 rotates synchronously, thereby causing the eccentric wheel 3 to rotate. The rotation of the eccentric wheel 3 strikes the sorting frame 2 and moves it up and down, causing the slider 8 to slide on the side wall of the fixed rod 9 and squeeze the first spring 10. This causes the sorting frame 2 to vibrate up and down, so that the waste concrete is separated and discharged by the screens 12 with different apertures during the up and down shaking process, thereby realizing the grading and screening of waste concrete, which facilitates subsequent processing.

[0040] When fixing and installing the screen 12, insert the fixing plate 13 into the sorting frame 2, then press the pull ring 18 to move the connecting post 17 downward, causing the second spring 24 to contract under pressure. As the connecting post 17 moves, the connecting block 19 enters the interior of the locking block 21, and at the same time, the locking post 20 also fits into the interior of the screw 14. After inserting the screw 14 into the interior of the sorting frame 2, release the connecting post 17 to allow the second spring 24 to rebound, causing the connecting block 19 to disengage from the interior of the locking block 21. This allows the locking post 20 to open and abut against the side wall of the sorting frame 2. Then, by rotating the lever 16, the rotating block 15 is rotated to the surface of the sorting frame 2, fixing the fixing plate 13 inside the sorting frame 2, thus completing the installation of the screen 12.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
