Referring to fig. 1-2, a vibrating screen for dolomite and limestone comprises: comprises a screen box 1, a frame 2, a plurality of damping springs 3 and a vibrating motor 4; a screen box 1 is arranged on the frame 2; a plurality of damping springs 3 are arranged between the frame 2 and the screen box 1; the screen box 1 is provided with a vibration motor 4 for driving the screen box 1 to vibrate;

the screen box 1 is internally provided with a single-layer screen 11 which is obliquely arranged, the screen box 1 is provided with an upper discharge hole 12 for leading out particles on the upper side of the single-layer screen 11 and a lower discharge hole 13 for leading out particles on the lower side of the single-layer screen 11, and the upper side of the screen box 1 is provided with a feed inlet 14; a cleaning structure 5 for cleaning the single-layer screen 11 is arranged in the screen box 1;

the cleaning structure 5 comprises a cleaning block 51, a driving rod 52, a driven rod 53, a driving motor 54, two sliding blocks 55, two cleaning rollers 56 and two cleaning motors 57;

the cleaning block 51 and the two cleaning rollers 56 are movably arranged on the upper surface of the single-layer screen 11; the left end and the right end of the cleaning block 51 are respectively fixedly connected with the two sliding blocks 55; the left end and the right end of each cleaning roller 56 are respectively and rotatably arranged on the two sliding blocks 55; the cleaning block 51 is disposed between the two cleaning rollers 56; two cleaning motors 57 are respectively arranged on one of the slide blocks 55, and each cleaning motor 57 is in transmission connection with a cleaning roller 56; the cleaning motor 57 is used for driving the corresponding cleaning roller 56 to rotate;

the cleaning block 51 and the two cleaning rollers 56 are provided between the driving lever 52 and the driven lever 53; the driving motor 54 is fixedly arranged in the screen box 1; one end of the driving rod 52 is in transmission connection with a driving motor 54, the other end of the driving rod 52 is in rotary connection with the sieve box 1, and the driving motor 54 is used for driving the driving rod 52 to rotate; two ends of the driven rod 53 are respectively and fixedly arranged in the sieve box 1; one of the sliding blocks 55 is in threaded connection with the driving rod 52, and the other sliding block 55 is movably sleeved on the driven rod 53; the movement of the slide 55 along the drive rod 52 causes the two cleaning rollers 56 and the cleaning block 51 to clean the upper surface of the single-layer screen 11.

In the present embodiment, the cleaning block 51 has a rectangular frustum structure, and the bottom surface of the cleaning block 51 is parallel to and in contact with the upper surface of the single-layer screen 11.

In the present embodiment, the driving rod 52 and the driven rod 53 are parallel to each other, and the central axes of the driving rod 52 and the driven rod 53 are parallel to the upper surface of the single-layer screen 11.

In this embodiment the single layer screen 11 has a filter diameter of 5-10 mm.

The working principle is as follows: when dolomite, lime stone are with shale shaker normal operating, the ore granule drops on single-deck sieve 11 below feed inlet 14 after getting into sieve case 1 from feed inlet 14. The single-layer screen 3 is used for separating large-particle ore grains to the upper side of the single-layer screen 11 and leading out from an upper discharge port 12, and separating small-particle ore grains to the lower side of the single-layer screen 11 and leading out from a lower discharge port 13. In the process, the two cleaning rollers 56 and the cleaning block 51 are stopped at the upper end of the highest point of the single-layer screen 11, so that the normal blanking of ore particles is not hindered.

When the vibrating screen for dolomite and limestone needs to clean the single-layer screen 11, the driving motor 54 can be started to drive the driving rod 52 to rotate, so that the two sliding blocks 55 drive the two cleaning rollers 56 and the cleaning block 51 to move along the driving rod 52 towards the inclined direction of the single-layer screen 11, the two cleaning motors 57 respectively drive the two cleaning rollers to rotate so as to clean the upper surface of the single-layer screen 11, and the cleaning block 51 can shovel off the caking on the upper surface of the single-layer screen 11 in the moving process. When the slide block 55 moves to the position below the lowest point of the single-layer screen 11, the driving motor 54 rotates reversely, the two cleaning rollers 56 and the cleaning block 51 move back, and the upper surface of the single-layer screen 11 is continuously cleaned. After completion of cleaning, the two cleaning rollers 56 and the cleaning block 51 move to the upper end of the highest point of the single-layer screen 11.

In this embodiment, the ore particles are dolomite or limestone particles.

The utility model has been described in general terms in the foregoing, but it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the utility model. Therefore, modifications or improvements are within the scope of the utility model without departing from the spirit of the inventive concept.
