[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] Such as Figures 1 - 5As shown in the figure, a screening device for dolomite powder includes a bracket 1. A power assembly 2 is fixedly connected to the bracket 1. A screening boat 3 is rotatably connected to the power assembly 2. The front side of the screening boat 3 is rotatably connected to the bracket 1. A crushing mechanism 4 is fixedly connected to the screening boat 3. A clamping mechanism 5 is fixedly connected to the lower side of the screening boat 3. A screening plate 6 is fixedly connected inside the screening boat 3. The screening boat 3 includes a rear support block 301 rotatably connected to the output end of the power assembly 2. The rear support block 301 is fixedly connected with a housing 302. The crushing mechanism 4 is fixedly connected to the upper side of the housing 302. A first discharge pipe 303 is fixedly connected to one side of the housing 302. A second discharge pipe 304 is arranged on one side of the first discharge pipe 303. The second discharge pipe 304 is fixedly connected to the housing 302. A third discharge pipe 305 is fixedly connected to the lower side of the housing 302. The lower ends of the first discharge pipe 303, the second discharge pipe 304 and the third discharge pipe 305 are fixedly connected with the clamping mechanism 5. A turning door 306 is rotatably connected to the front side of the housing 302. An observation window is arranged on the turning door 306. The observation window on the turning door 306 is sealed with a transparent material. A front support block 307 is fixedly connected to the front side of the housing 302. Symmetrically arranged driven eccentric wheels 309 are rotatably connected to the front support block 307. The driven eccentric wheels 309 are rotatably connected to the bracket 1. A number of internally symmetrically arranged inner support frames 308 are fixedly connected inside the housing 302. The screening plate 6 is detachably connected to the inner support frames 308. The output end of the power assembly 2 is connected with an eccentric wheel. The eccentric wheel on the power assembly 2 is rotatably connected to the rear support block 301. After the dolomite powder enters the screening boat 3, it falls onto the screening plate 6. The power assembly 2 rotates to drive the rear support block 301 to perform a rotary motion, thereby driving the entire housing 302 to move. The driven eccentric wheels 309 follow the movement of the housing 302. The movement of the housing 302 drives the screening plate 6 to move, completing the screening work of the dolomite powder. The screened dolomite powder leaves the screening boat 3 from the corresponding discharge pipes. After the screening boat 3 stops moving, the staff can open the turning door 306, take out the screening plate 6 for cleaning, or clean the inside of the screening boat 3 through the turning door 306. In this way, the screening of the dolomite powder can be completed, and the screening boat 3 can be cleaned after the work is finished.

[0026] The crushing mechanism 4 includes a feed hopper 401 fixedly connected to the housing 302. A motor 402 is fixedly connected to the feed hopper 401. The output end of the motor 402 is fixedly connected with a crushing roller 403. A number of crushing paddles are fixedly connected to the crushing roller 403. A number of symmetrically arranged baffles 404 are fixedly connected inside the feed hopper 401. The baffles 404 are arranged in a staggered manner with the crushing paddles on the crushing roller 403. The motor 402 rotates to drive the crushing roller 403 to rotate. Since the dolomite powder tends to form lumps when it is damp, which is not conducive to the screening of the dolomite powder, the rotating crushing roller 403 can crush the lumped dolomite powder.

[0027] The clamping mechanism 5 includes a fixed block 502 fixedly connected to the first discharge pipe 303, the second discharge pipe 304 and the third discharge pipe 305. On one side of the fixed block 502, a bidirectional screw 504 is rotatably connected. The bidirectional screw 504 is symmetrically provided with threads with opposite helix directions. One end of the bidirectional screw 504 is fixedly connected to a handle 501. On the other side of the fixed block 502, a guide rod 505 is fixedly connected. The bidirectional screw 504 is threadedly connected with symmetrically arranged clamping blocks 503. The clamping blocks 503 are slidably connected to the guide rod 505. Usually, dolomite powder is packaged and stored in a packaging bag. The staff puts the opening of the packaging bag on the lower end of the discharge pipe, rotates the handle 501 to drive the bidirectional screw 504 to rotate. The rotation of the bidirectional screw 504 drives the clamping blocks 503 to move horizontally towards each other, clamping the opening of the packaging bag at the lower end of the discharge pipe, so as to prevent other substances from mixing into the packaging bag.

[0028] The screening plate 6 includes a first sieve plate 601 detachably connected to the inner support frame 308. A second sieve plate 602 is arranged below the first sieve plate 601. The second sieve plate 602 is detachably connected to the inner support frame 308. The diameter of the sieve holes on the first sieve plate 601 is larger than the diameter of the sieve holes on the second sieve plate 602. The setting of multiple sieve plates can realize the multi-stage screening of dolomite powder.

[0029] Working principle: The staff puts the opening of the packaging bag on the lower end of the discharge pipe, rotates the handle 501 to drive the bidirectional screw 504 to rotate. The rotation of the bidirectional screw 504 drives the clamping blocks 503 to move horizontally towards each other, clamping the opening of the packaging bag at the lower end of the discharge pipe. The dolomite powder enters the screening device from the feed hopper 401, is crushed by the crushing roller 403, and enters the sieve boat 3. After the dolomite powder enters the sieve boat 3, it falls onto the screening plate 6. The power assembly 2 rotates to drive the rear support block 301 to perform a rotary motion, thereby driving the entire outer shell 302 to move. The driven eccentric wheel 309 follows the movement of the outer shell 302. The movement of the outer shell 302 drives the screening plate 6 to move, completing the screening work of the dolomite powder. The screened dolomite powder leaves the sieve boat 3 from the corresponding discharge pipe. After the sieve boat 3 stops moving, the staff can open the flip door 306, take out the screening plate 6 for cleaning, or clean the inside of the sieve boat 3 through the flip door 306. In this way, the screening of dolomite powder can be completed, and the sieve boat 3 can be cleaned after the work is finished.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
