[0027] Please refer to Figures 1-5 , a multi-stage swing sieve, including a sieve material box 1. An unlocking component is arranged inside the sieve material box 1 through a fixing component. The unlocking component includes a second filter plate 2, a third filter plate 3, a fixing rod 4, a mounting sleeve 5, a rotating block 6 and a connecting block 7. The second filter plate 2 and the third filter plate 3 are detachably installed inside the sieve material box 1. The fixing rod 4 is fixedly installed inside the sieve material box 1. The mounting sleeve 5 is slidably connected to the outside of the fixing rod 4. One end of the mounting sleeve 5 abuts against the second filter plate 2. The rotating block 6 is rotatably connected to the mounting sleeve 5. The connecting block 7 is installed on the rotating block 6. The fixing component includes an insertion groove 8, an insertion rod 9 and an insertion block 10. The insertion groove 8 is opened on the inner sides of the fixing rod 4 and the mounting sleeve 5. The insertion rod 9 is slidably connected to the fixing rod 4 and the mounting sleeve 5. The insertion block 10 is connected to the insertion rod 9. A sieving component is arranged on the outside of the sieve material box 1.

[0028] A rotating rod 11 is connected to the connecting block 7, and a limiting block 12 is installed on the mounting sleeve 5.

[0029] A tension spring 13 is connected between the limiting block 12 and the connecting block 7.

[0030] A first spring 14 is connected to the insertion rod 9. The two ends of the first spring 14 are respectively connected to the insertion block 10 and the inner side of the mounting sleeve 5. A clamping block 15 is connected to the insertion rod 9. The clamping block 15 is adapted to the rotating rod 11. The two ends of the insertion rod 9 are rotatably connected with a first hinge rod 16 and a second hinge rod 17. One end of the second hinge rod 17 is rotatably connected to the mounting sleeve 5.

[0031] A third articulated rod 18 is rotatably connected to the second articulated rod 17. One end of the third articulated rod 18 is rotatably connected to the mounting sleeve 5. A moving block 19 is mounted on the first articulated rod 16. A moving groove 20 is formed in the mounting sleeve 5. The moving block 19 is slidably connected to the moving groove 20. One end of the moving block 19 and one end of the mounting sleeve 5 are connected with a second spring 21.

[0032] In this embodiment, during use, when the second filter plate 2 and the third filter plate 3 need to be replaced, manually rotate the rotating block 6 along the outer side of the mounting sleeve 5. During the rotation process, the rotating rod 11 is driven to move, and the tension spring 13 between the connecting block 7 and the limiting block 12 is compressed. During the movement of the rotating rod 11, it is taken out from the clamping block 15. At this time, manually pull the insertion rod 9 to pull it outwards. During the pulling process, the insertion block 10 is driven to move, so that the insertion block 10 is taken out from the insertion groove 8, and the first spring 14 can be compressed to release the fixation of the fixed rod 4. Then, during the movement of the insertion rod 9, the moving block 19 at one end of the first articulated rod 16 moves along the moving groove 20 on the mounting sleeve 5, and the second spring 21 is stretched, so as to mobilize the parts connected around it to release the fixation of the fixed rod 4. At this time, slide the mounting sleeve 5 out along the fixed rod 4, then slide the second filter plate 2 and the third filter plate 3 out along the fixed rod 4, and then slide the mounting sleeve 5 into the fixed rod 4. Under the action of the first spring 14, the insertion block 10 is inserted into the fixed rod 4 to complete the fixation of the fixed rod 4. Then, under the action of the second spring 21, the moving block 19 is driven to slide along the moving groove 20 to the initial position of the moving groove 20, and the first articulated rod 16, the second articulated rod 17 and the third articulated rod 18 are restored to the initial state. At this time, release the rotating block, and under the action of the tension spring 13, the rotating rod 11 is driven to move onto the clamping block 15 to complete the fixation process.

[0033] Please refer to Figures 1-2 , as a multi-stage shaking screen implementation mode of the screening and moving assembly: the screening and moving assembly includes a third spring 22, a fixed seat 23 and a vibrator 24. The third spring 22 is arranged at the bottom of the screening box 1. The fixed seat 23 is fixedly installed on the third spring 22. The vibrator 24 is installed on the screening box 1.

[0034] On one side of the screening box 1, an installation frame 25 is installed. On the installation frame 25, a motor 26 is installed. The output end of the motor 26 is connected with a main transmission wheel 27. On the installation frame 25, a fixed frame 28 is installed. There are two fixed frames 28. A transmission shaft 29 is rotatably connected between the fixed frames 28. One end of the transmission shaft 29 is connected with a driven transmission wheel 30. A transmission belt 31 is connected between the main transmission wheel 27 and the driven transmission wheel 30.

[0035] One end of the transmission shaft 29 is connected with a conveying wheel 32. A conveying shaft 33 is connected to the conveying wheel 32. A moving box 34 is connected to the conveying shaft 33. A first filter plate 35 is installed on the moving box 34. Moving wheels 36 are installed at the bottom of the moving box 34. The moving wheels 36 are slidably connected to the installation frame 25. First leakage outlets 37 and second leakage outlets 38 are opened at both the upper and lower ends of the moving box 34.

[0036] More specifically, during use, the material to be screened is manually placed on the moving box 34. At this time, the motor 26 is manually started to drive the main transmission wheel 27 at its output end to rotate. Thus, under the action of the transmission belt 31, the driven transmission wheel 30 is driven to rotate. Thus, under the action of the transmission shaft 29 on the fixed frame 28, the conveying wheel 32 is driven to rotate. Thus, the conveying shaft 33 is driven to move, so that the moving box 34 is driven to move along the installation frame 25 by the moving wheels 36 at the bottom. During its movement, screening is carried out using the first filter plate 35, so that large pieces of material flow out from the first leakage outlets 37, while fine material falls to the lower end and flows out along the second leakage outlets 38, and then flows into the screening box 1. Then, the vibrator 24 is manually started to drive the screening box 1 to vibrate, and the third spring 22 is used to play a buffering role, thus completing the screening process of the material.

[0037] In summary, during use, when the second filter plate 2 and the third filter plate 3 need to be replaced, manually rotate the rotating block 6 along the outer side of the mounting sleeve 5. During the rotation process, the rotating rod 11 is driven to move, and the tension spring 13 between the connecting block 7 and the limiting block 12 is compressed. During the movement of the rotating rod 11, it is removed from the clamping block 15. At this time, manually pull the insertion rod 9 to pull it outwards. During the pulling process, the insertion block 10 is driven to move, and the insertion block 10 is removed from the insertion slot 8, and the first spring 14 can be compressed to release the fixation of the fixing rod 4. Then, during the movement of the insertion rod 9, the moving block 19 at one end of the first hinge rod 16 is driven to move along the moving slot 20 on the mounting sleeve 5, and the second spring 21 is stretched, so as to mobilize the parts connected around it to release the fixation of the fixing rod 4. At this time, slide the mounting sleeve 5 out along the fixing rod 4, then slide the second filter plate 2 and the third filter plate 3 out along the fixing rod 4, and then slide the mounting sleeve 5 into the fixing rod 4. Under the action of the first spring 14, the insertion block 10 is inserted into the fixing rod 4 to complete the fixation of the fixing rod 4. Then, under the action of the second spring 21, the moving block 19 is driven to slide along the moving slot 20 to the initial position of the moving slot 20, and the first hinge rod 16, the second hinge rod 17 and the third hinge rod 18 return to the initial state. At this time, release the rotating block, and under the action of the tension spring 13, the rotating rod 11 is driven to move onto the clamping block 15 to complete the fixation process.

[0038] During use, manually put the material to be screened onto the moving box 34. At this time, manually start the starting motor 26 to drive the main transmission wheel 27 at its output end to rotate. Thus, under the action of the transmission belt 31, the driven transmission wheel 30 is driven to rotate. Then, under the action of the transmission shaft 29 on the fixed frame 28, the conveying wheel 32 is driven to rotate, so as to drive the conveying shaft 33 to move, and the moving box 34 is mobilized to move along the mounting frame 25 by the moving wheels 36 at the bottom. During the movement process, screening is carried out by using the first filter plate 35, so that the large pieces of material flow out from the first leakage outlet 37, and the fine material falls to the lower end and flows out along the second leakage outlet 38, and then flows into the screening box 1. Then, manually start the vibrator 24 to drive the screening box 1 to vibrate, and the third spring 22 plays a buffering role to complete the screening process of the material.
