[0002] In the field of construction waste recycling and processing, efficient sorting equipment is a key link in achieving graded utilization of waste. Construction waste has a complex composition, including various materials such as bricks, concrete blocks, metals, and wood, and its particle size varies significantly. It needs to be accurately sorted through screens of different mesh sizes to meet the needs of different applications such as recycled aggregates and fillers.

[0003] However, traditional vibrating sorting equipment usually uses screens with a fixed mesh size. Fixed screens cannot adjust the mesh size according to changes in waste particles. The sorting accuracy needs to be adjusted manually by disassembling and replacing the screen. However, manual screen replacement requires stopping the machine, and the disassembly process is cumbersome and time-consuming, affecting the screening efficiency. Utility Model Content

[0004] Based on the aforementioned technical problems regarding traditional vibratory sorting equipment that typically uses screens with fixed mesh sizes, which cannot adjust the mesh size according to changes in waste particle size, manual replacement of the screen is required to adjust the sorting accuracy. However, manual replacement of the screen requires machine shutdown, which is cumbersome and time-consuming, affecting the screening efficiency. Therefore, this utility model proposes a vibratory sorting equipment for construction waste.

[0005] This utility model proposes a vibratory sorting device for construction waste, including a mounting frame, a screening screen, and a switching component;

[0006] The mounting frame is rotatably connected to the inner sides of its four corners, and the axes of the four sets of rotating shafts are parallel and located on the same horizontal plane.

[0032] like Figure 1 and Figure 2 Figure 4 , Figure 6 and Figure 7 As shown, a vibratory sorting device for construction waste includes a mounting frame 15, a screening screen 6, and a switching assembly.

[0033] The mounting frame 15 has four rotating shafts 2 rotatably connected to the inner sides of its four corners. The axes of the four sets of rotating shafts 2 are parallel and located on the same horizontal plane.

[0034] The screening screen 6 has a first screen 601, a second screen 602, a third screen 603 and a fourth screen 604 distributed at intervals, and the mesh number of each screen decreases sequentially according to the winding order; a positioning part 605 is fixedly connected between adjacent screens, and the outer wall of the screening screen 6 is slidably fitted with the rotating shaft 2;

[0035] The rotating shaft 2 provides rolling support for the screening screen 6, and the four sets of parallel rotating shafts 2 can ensure the smooth operation of the screening screen 6;

[0036] Screening Mesh 6 integrates multi-mesh screens, and the mesh number can be continuously adjusted by switching components, which solves the pain point of traditional equipment where fixed screens need to be replaced manually;

[0037] The switching assembly includes two clamping rollers 4, two support plates 8, and a connecting shaft 11;

[0038] Two clamping rollers 4 are used to clamp and convey the screening screen 6;

[0039] The ends of the two support plates 8 are fixedly connected to the mounting frame 15 respectively, and a worm gear 9 is rotatably connected between the two support plates 8. A rocker handle 10 is fixedly connected to the end of the worm gear 9.

[0040] The end of the connecting shaft 11 is fixedly connected to the end of one of the clamping rollers 4, and a worm gear 12 is fixedly connected to the outer wall of the connecting shaft 11, with the worm 9 meshing with the worm gear 12.

[0041] In the switching assembly, the worm gear 9 and worm wheel 12 transmission structure realizes manual switching of the screen through the rocker handle 10, without stopping the machine, which is simple to operate, improves the sorting accuracy adjustment efficiency, and meets the sorting needs of different waste particles.

[0042] In some embodiments, such as Figure 5 As shown, double-sided toothed plates 7 are fixedly connected to both sides of the screening screen 6, and gears 5 are fixedly connected to both ends of the clamping roller 4. The gears 5 mesh with the double-sided toothed plates 7.

[0043] The meshing design of the double-sided toothed plate 7 and the gear 5 ensures accurate positioning and smooth operation when the screen 6 is switched, preventing the screen from shifting or jamming during vibration.

[0044] In some embodiments, such as Figure 6 As shown, an inclined first hopper 14 is fixedly connected to the inner wall of the mounting frame 15, and the end of the first hopper 14 passes through the side wall of the mounting frame 15 and extends to its outer side.

[0045] The inclined design of the first hopper 14 facilitates the rapid discharge of qualified small particle waste, avoiding material accumulation that could affect screening efficiency.

[0046] In some embodiments, such as Figure 1 As shown, an inclined second hopper 16 is fixedly connected to the inner wall of the mounting frame 15, and the second hopper 16 is located at the discharge end of the screening screen 6.

[0047] The second hopper 16 is used to collect large particles of waste that have not passed through the current screen.

[0048] In some embodiments, such as Figure 1 As shown, the vibratory sorting equipment also includes a base 1. Support rods 17 are slidably connected to the four corners of the bottom of the mounting frame 15. The bottom of the support rods 17 is fixedly connected to the base 1. Springs 18 are fitted on the outer walls of the support rods 17. Limit sleeves 19 are fixedly connected to the outer walls of the support rods 17. A shock-absorbing pad 20 is fixedly connected to the top of the base 1. A vibration motor 21 is fixedly connected to the top of the shock-absorbing pad 20. The output end of the vibration motor 21 is fixedly connected to the bottom of the mounting frame 15. One end of the spring 18 is fixedly connected to the base 1, and the other end of the spring 18 is fixedly connected to the mounting frame 15.

[0049] The elastic cushioning effect of spring 18 reduces the impact of vibration on base 1, the limiting sleeve 19 and the shock-absorbing pad 20 ensure the stability of mounting frame 15 when vibrating, and the vibration motor 21 provides uniform high-frequency vibration, so that waste is fully dispersed on the screen.

[0050] In some embodiments, such as Figure 3 As shown, a frame 3 is fixedly connected to the inner wall of the mounting frame 15. The frame 3 is located above the first feeding hopper 14. A bracket 13 is fixedly connected to the inner wall of the frame 3. The bracket 13 is used to support the screening screen 6.

[0051] The frame 3 and bracket 13 provide central support for the screen 6, preventing the screen 6 from sagging or deforming during vibration, and reducing the slack caused by gravity, ensuring consistent screen tension and improving screening accuracy.

[0052] Working principle: The worm 9 is rotated by the crank 10, and the worm 9 meshes with the worm wheel 12, which drives the connecting shaft 11 and the clamping roller 4 to rotate, driving the screening screen 6 to roll along the rotating shaft 2, so that the first screen 601, the second screen 602, the third screen 603 and the fourth screen 604 enter the sorting area in sequence.

[0053] After the vibration motor 21 is started, the vibration is transmitted to the mounting frame 15 through the shock-absorbing pad 20, causing the screen 6 to vibrate at a high frequency. Under the action of vibration, the waste particles smaller than the current screen mesh number fall through the screen holes into the first discharge hopper 14 and are discharged, while the waste particles larger than the screen mesh number move along the screen 6 to the lower end and are finally discharged through the second discharge hopper 16.

[0054] When the sorting accuracy needs to be adjusted, there is no need to stop the machine. Simply turn the crank 10 to switch to the screen with the target mesh size. The positioning part 605 ensures that the position is accurate when the screen is switched.

[0055] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
