The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] The powder screening mechanism disclosed in this utility model is easy to disassemble and is mainly used in powder screening scenarios.
[0024] Reference Figures 1 to 4 A powder screening mechanism that is easy to disassemble includes: a mounting frame 1, a mounting rod 2 fixedly connected inside the mounting frame 1, a screening chamber 3 provided at the top of the mounting rod 2, a base 4 fixedly connected at the bottom of the screening chamber 3, the inside of the base 4 being rotatably connected to the outside of the mounting rod 2, a filter plate 5 slidably connected inside the screening chamber 3, a connecting component provided on one side of the screening chamber 3 for fixing the filter plate 5, a connecting plate 6 fixedly connected on one side of the mounting frame 1, a vertical plate 7 fixedly connected at the top of the connecting plate 6, a vibration component provided on one side of the screening chamber 3, a collection frame 25 provided at the bottom of the inner wall of the mounting frame 1, and a shaking component provided on one side of the vertical plate 7;
[0025] The connecting assembly includes a fixing block 8, which is fixedly connected to one side of the screening chamber 3 at equal intervals. A slide rod 9 is slidably connected inside the fixing block 8. A limiting block 10 is fixedly connected to the bottom of the slide rod 9. A connecting strip 11 is fixedly connected to the top of the slide rod 9. A fixing rod 12 is rotatably connected to the bottom of the connecting strip 11. A spring 14 is provided on the outside of the slide rod 9.
[0026] A sleeve 13 is fixedly connected at equal intervals to the top of the filter plate 5, and the inside of the sleeve 13 is threadedly connected to the outside of the fixing rod 12.
[0027] In the above technical solution, considering that the filter plate of the vibrating screen is fixed by multiple bolts, long-term use may cause the filter plate to become clogged, but disassembling the bolts is difficult, and maintenance and replacement are inconvenient, the specific operation is as follows to solve this problem: By setting up a connecting assembly, first put the filter plate 5 into the screening chamber 3, then lift the multiple sets of connecting bars 11, the slide bar 9 slides upward inside the fixing block 8, the spring 14 is compressed, so that the bottom of the fixing rod 12 is higher than the top of the screening chamber 3, then rotate the connecting bar 11 to rotate the fixing rod 12 into the screening chamber 3 and position it at the top of the sleeve 13, then release the connecting bar 11, under the rebound of the spring 14, drive the fixing rod 12 downward to the top of the sleeve 13, then rotate the fixing rod 12 to screw it into the sleeve 13. The filter plate 5 is installed in the screening chamber 3, and the material is poured into the screening chamber 3. The vibrating component moves the filter plate 5 up and down a short distance, and the shaking component moves the screening chamber 3 left and right, thus screening the material on the filter plate 5. The screened material falls to the bottom of the screening chamber 3 and is discharged from the outlet into the collection frame 25. After screening, the filter plate 5 is lifted upwards by the handle, causing the fixing rod 12, connecting bar 11, sliding rod 9, and limiting block 10 to move upwards. Then, the fixing rod 12 is rotated to unscrew the sleeve 13 and rotate outwards, lifting the filter plate 5 from above the screening chamber 3. The particles on the filter plate 5 are then poured out, and the through holes of the filter plate 5 are rinsed. Finally, the filter plate 5 is reinstalled in the screening chamber 3 for the next use. By setting up the connecting component, the filter plate 5 can be quickly installed and disassembled, avoiding the tedious bolt disassembly process, saving time and manpower, and making it easier to clean the filter plate 5, helping to clear blockages in a timely manner and improving screening efficiency.
[0028] Reference Figures 1 to 4 In a preferred embodiment, the vibration assembly includes a placement plate 15, which is fixedly connected to one side of the screening chamber 3. A first motor 16 is disposed on the top of the placement plate 15. A rotating rod 17 is rotatably connected inside the screening chamber 3. One end of the output shaft of the first motor 16 is fixedly connected to one end of the rotating rod 17. Two cams 18 are fixedly connected to the outer side of the rotating rod 17. The top of the cams 18 contacts the bottom of the filter plate 5. The shaking assembly includes a second motor 19, which is disposed on the top of the vertical plate 7. One end of the output shaft of the second motor 19 is fixedly connected to a turntable 20. One end of the turntable 20 is fixedly connected to an eccentric rod 21. A connecting block 22 is fixedly connected to one side of the screening chamber 3. A connecting rod 23 is rotatably connected between one side of the connecting block 22 and the outer side of the eccentric rod 21.
[0029] In the above technical solution, considering the problem of the simple screening structure of traditional vibrating screens, the specific operation is as follows: By setting up a vibration component and a shaking component, the material is poured onto the filter plate 5. Then, the first motor 16 is started to drive the rotating rod 17 to rotate, thereby driving the cam 18 to rotate inside the screening chamber 3. The contact between the cam 18 and the filter plate 5 will lift the filter plate 5, causing the filter plate 5 to vibrate up and down. At the same time, the second motor 19 is started to drive the turntable 20 and the eccentric rod 21 to rotate. Through the connecting rod 23, the screening chamber 3 is driven to swing slightly around the mounting rod 2, thereby causing the material to shake back and forth on the filter plate 5 to screen the material. By combining the vibration component and the shaking component with up and down vibration and left and right shaking, multi-directional violent shaking is achieved, which effectively enhances the screening effect, helps to prevent clogging, and improves the screening efficiency.
[0030] Reference Figures 1 to 4 In a preferred embodiment, a diversion slope 24 is fixedly connected to the bottom of the inner wall of the screening chamber 3; a threaded rod 26 is threadedly connected to the inside of the mounting frame 1, and a clamping block 27 is rotatably connected to one end of the threaded rod 26. One side of the clamping block 27 abuts against one side of the collection frame 25, and the bottom of the clamping block 27 is slidably connected to the bottom of the inner wall of the mounting frame 1. By setting the diversion slope 24 inside the screening chamber 3, the falling material can be guided to the outlet for easy discharge. The collection frame 25 can be fixed by using the threaded rod 26 and the clamping block 27, so that the collection frame 25 can be prevented from shifting during the vibrating screening of the equipment, which would cause the material to spill onto the ground.
[0031] Reference Figures 1 to 4 In a preferred embodiment, the first motor 16 and the second motor 19 are electrically connected to an external controller, respectively.
[0032] Working principle: In use, first place the filter plate 5 into the screening chamber 3, then lift the multiple sets of connecting strips 11. The slide rod 9 slides upward inside the fixed block 8, and the spring 14 is compressed, so that the bottom of the fixed rod 12 is higher than the top of the screening chamber 3. Then rotate the connecting strips 11 to rotate the fixed rod 12 into the screening chamber 3 and position it at the top of the sleeve 13. Then release the connecting strips 11. Under the rebound of the spring 14, the fixed rod 12 moves downward to the top of the sleeve 13. Then rotate the fixed rod 12 to screw it into the sleeve 13, install the filter plate 5 in the screening chamber 3, and then pour the material into the screening chamber 3. Then start the first motor 16 to drive the rotating rod 17 to rotate, thereby driving the cam 18 to rotate inside the screening chamber 3. The contact between the cam 18 and the filter plate 5 will lift the filter plate 5, causing the filter plate 5 to vibrate up and down. At the same time, start the second motor. 19. The rotating disc 20 and eccentric rod 21 are driven to rotate, which is transmitted through the connecting rod 23, causing the screening chamber 3 to swing slightly around the mounting rod 2 as the center. This causes the material to sway back and forth on the filter plate 5, screening the material on the filter plate 5. The screened material falls to the bottom of the screening chamber 3 and is discharged from the outlet into the collection frame 25. After the screening is completed, the filter plate 5 is lifted upward by the handle. This causes the fixing rod 12, connecting bar 11, sliding rod 9 and limiting block 10 to move upward. Then the fixing rod 12 is rotated to unscrew the sleeve 13 and rotate outward. Then the filter plate 5 is lifted from above the screening chamber 3, the particles on the filter plate 5 are poured out, and the through holes of the filter plate 5 are rinsed. Finally, the filter plate 5 is reinstalled in the screening chamber 3 for the next use. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
