[0030] In the embodiment, the locking mechanism 3 is provided with two groups and is arranged on the inner wall of the vibration equipment body 2. The locking mechanism 3 comprises a first servo motor 31, a gear 32, a limiting column 33, a rack 34, a moving rod 35 and a locking column 36. The first servo motor 31 penetrates through the surface of the vibration equipment body 2. The output end of the first servo motor 31 is fixedly connected with the gear 32. The surface of the gear 32 is fixedly connected with the limiting column 33. The bottom of the gear 32 is engaged with the rack 34. The side surface of the rack 34 is fixedly connected with the moving rod 35. The side surface of the moving rod 35 is fixedly connected with the locking column 36. Through the arrangement of the two groups of locking mechanisms 3, the staff can install the three groups of sub-sieve baskets 10 in the interior of the vibration equipment body 2 through the two groups of locking mechanisms 3. The staff can also disassemble the three groups of sub-sieve baskets 10 from the interior of the vibration equipment body 2 through the two groups of locking mechanisms 3.

[0031] In the embodiment, the surface of the lead screw 5 is provided with two groups of threads in opposite directions. The two groups of thread surfaces of the lead screw 5 are engaged with the sliding blocks 6. The top of the vibration equipment body 2 is provided with horizontal grooves matched with the two groups of sliding blocks 6. Because the surface of the lead screw 5 is provided with two groups of threads in opposite directions and the two groups of sliding blocks 6 are engaged with the threads respectively, when the lead screw 5 rotates, the two groups of sliding blocks 6 will relatively slide and approach each other in the horizontal grooves at the top of the vibration equipment body 2.

The transmission rods 7 and the fixed columns 8 are respectively provided with two groups.

Because the two groups of transmission rods 7 are fixedly connected with the two groups of sliding blocks 6 respectively, when the two groups of sliding blocks 6 slide, the two groups of transmission rods 7 will relatively move and approach each other. At this time, the two groups of fixed columns 8 fixedly connected with the two groups of transmission rods 7 will be embedded into the circular holes in the surfaces and back surfaces of the vibration equipment body 2 and the dust suppression cover 9, and the dust suppression cover 9 will be fixed at the current position.

[0035] In this embodiment, each locking mechanism 3 is provided with two sets of limiting posts 33. The inner wall of the vibrating device body 2 is provided with an annular groove that matches the limiting posts 33. The limiting posts 33 are embedded in the annular groove of the inner wall of the vibrating device body 2 and are slidably connected to the vibrating device body 2. Since the two sets of limiting posts 33 are fixedly connected to the gear 32, when the gear 32 rotates, it will drive the two sets of limiting posts 33 to slide in the annular groove of the inner wall of the vibrating device body 2, and play a certain limiting effect on the gear 32.

[0036] In this embodiment, each locking mechanism 3 is provided with three sets of locking pins 36.

The locking pins 36 are inserted into the round holes on the sides of the mounting plate 12 and the connecting rod 11 through the moving rod 35. When the locking pins 36 are inserted into the round holes on the sides of the connecting rod 11 and the mounting plate 12, the connecting rod 11 and the mounting plate 12 can be locked together. When the locking pins 36 are pulled out from the round holes on the sides of the connecting rod 11 and the mounting plate 12, the connecting rod 11 and the mounting plate 12 can be separated, and the sieve basket 10 can be removed.

[0037] Example 2

[0038] Based on Embodiment 1, a preferred embodiment of the multi-stage vibrating screen screening and dust removal device provided by this utility model is, for example... Figures 1 to 6 As shown: A connecting column 16 is fixedly connected to the bottom of the base plate 1, and a shock-absorbing base 17 is attached to the bottom of the connecting column 16. A spring shock absorber 18 is installed inside the shock-absorbing base 17.

[0039] In this embodiment, four sets of connecting columns 16 and shock-absorbing bases 17 are respectively provided. The top of the shock-absorbing base 17 is provided with a circular groove that matches the connecting column 16. Each set of shock-absorbing bases 17 is provided with four sets of spring shock absorbers 18. By embedding the four sets of connecting columns 16 at the bottom of the base plate 1 into the circular grooves at the top of the four sets of shock-absorbing bases 17, the base plate 1 can be installed on the top of the shock-absorbing base 17, thereby connecting the vibrating device body 2 with the shock-absorbing base 17. Because the vibrating device body 2 will produce a certain amount of shaking when it is working, the shock-absorbing base 17 will reduce the shaking effect through the spring shock absorbers 18 inside, thereby enhancing the stability of the vibrating device body 2.

[0040] The working principle and use process of the utility model are as follows: firstly, four groups of damping bases 17 are placed on the ground, then four groups of connecting columns 16 at the bottom of the bottom plate 1 are respectively embedded into the inside of the circular grooves at the top of the four groups of damping bases 17, namely the bottom plate 1 can be installed on the top of the damping base 17, then the vibration equipment main body 2 is connected with the damping base 17, subsequently, the equipment door on the left side of the vibration equipment main body 2 is opened, then the three groups of connecting rods 11 at the two sides of the sieve basket 10 are respectively embedded into the inside of the grooves at the top of the six groups of mounting plates 12, so that the circular holes at the side of the connecting rod 11 correspond to the circular holes at the side of the mounting plate 12, then the connecting rod 11 and the mounting plate 12 are locked through the two groups of locking mechanisms 3, namely the purpose of installing the sieve basket 10 is achieved, then the first collecting box 14 and the second collecting box 15 are respectively placed below the sieve basket 10 and below the discharging plate 13, subsequently, the dust suppression cover 9 is pulled out from the groove at the side of the vibration equipment main body 2, so that the circular holes on the surface and the back of the dust suppression cover 9 correspond to the circular holes on the surface and the back of the vibration equipment main body 2, then the second servo motor 4 is started to drive the lead screw 5 to rotate clockwise, because the surface of the lead screw 5 is provided with two groups of opposite threads, and the two groups of sliding blocks 6 are respectively engaged with the threads, so when the lead screw 5 rotates, the two groups of sliding blocks 6 are respectively relatively slid and close to each other in the horizontal groove at the top of the vibration equipment main body 2, because the two groups of transmission rods 7 are respectively fixedly connected with the two groups of sliding blocks 6, so when the two groups of sliding blocks 6 slide, the two groups of transmission rods 7 are relatively moved and close to each other, at this time, the two groups of fixed columns 8 fixedly connected with the two groups of transmission rods 7 are embedded into the circular holes on the surface and the back of the vibration equipment main body 2 and the dust suppression cover 9, and the dust suppression cover 9 is fixed at the current position, at this time, the dust suppression cover 9 reduces the dust raising area, thereby playing a dust suppression role, and further protecting the health of the workers.

[0041] Subsequently, the material can be fed through the feeding port at the top of the vibration equipment main body 2, and the vibration equipment main body 2 is started to drive the three groups of sieve baskets 10 to sieve, subsequently, the material is slid into the inside of the second collecting box 15 through the discharging plate 13, because the vibration equipment main body 2 shakes when working, so at this time, the damping base 17 plays a certain effect of reducing the shaking through the spring shock absorber 18 in the inside, thereby enhancing the stability of the vibration equipment main body 2;

[0042] After screening, when the three groups of screening baskets 10 need to be disassembled, the equipment door on the left side of the vibration equipment body 2 can be opened, and then the first servo motor 31 is controlled to drive the gear 32 to rotate counterclockwise. Because the two groups of limiting columns 33 are fixedly connected with the gear 32, when the gear 32 rotates, it will drive the two groups of limiting columns 33 to slide in the annular groove on the inner wall of the vibration equipment body 2, and play a certain limiting effect on the gear 32. Because the rack 34 is engaged with the gear 32, when the gear 32 rotates, it will drive the rack 34 to slide to the left. At this time, the moving rod 35 fixedly connected with the rack 34 will drive the three groups of locking columns 36 to be extracted from the circular holes on the sides of the three groups of connecting rods 11 and the three groups of mounting plates 12, and then the same method is used to extract the three groups of locking columns 36 in the other group of locking mechanisms 3 from the circular holes on the sides of the other three groups of connecting rods 11 and the three groups of mounting plates 12. At this time, the three groups of screening baskets 10 can be lifted upwards, so that the six groups of connecting rods 11 are extracted from the recesses of the six groups of mounting plates 12, and the screening baskets 10 can be disassembled, so as to realize the purpose of convenient installation and disassembly of the screening baskets 10.

[0043] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
