There are two through slots 2, which are distributed on the left and right. The inner surface of the through slot 2 is adapted to the slider 4. The outer surface of the connecting rod 8 is slidably connected to the housing 1. The outer surface of the rotating shaft 13 is rotatably connected to the fixing plate 15. The lower surface of the fixing plate 15 is fixedly connected to the motor 14. The motor 14 is electrically connected to an external power source.

[0028] A snap-fit ​​seat 19 is fixedly connected to the front surface of the filter frame 7, and a handle 20 is fixedly connected to the outer surface of the snap-fit ​​seat 19. A fixing box 21 is fixedly connected to the front surface of the screen frame 5. A limiting groove 22 is provided on the outer surface of the fixing box 21. A sliding rod 23 is fixedly connected to the inner surface of the limiting groove 22. A spring 24 is provided on the outer surface of the sliding rod 23. A handle 25 is slidably connected to the outer surface of the sliding rod 23. An insert block 26 is fixedly connected to the lower surface of the handle 25.

[0029] Working Principle: During operation, firstly, select the corresponding filter frame 7 according to the required fineness of the ore powder to be screened. Then, pull the handle 25 upwards along the inside of the limiting groove 22 to drive the insert 26 out of the insertion hole 27 and compress the spring 24, thus releasing the restriction on the existing filter frame 7. Then, pull the handle 20 to remove the existing filter frame 7. Next, insert the selected new filter frame 7 into the slot 6. When the insertion hole 27 on the latch seat 19 corresponds to the insert 26, release the handle 25. Under the rebound force of the spring 24, the insert 26 will automatically insert into the insertion hole 27, thereby completing the fixed installation of the new filter frame 7 to screen the required fineness. Mineral powder is poured into the screen frame 5, and the motor 14 is started. Under the action of the motor 14, the rotating shaft 13 drives the turntable 12 to rotate, which in turn, together with the connecting column 11, connecting bar 10 and fixed column 9, drives the connecting rod 8 to move back and forth. This causes the screen frame 5 to move back and forth along the guide rod 3 via the slider 4. At this time, under the action of the filter screen frame 7, the finer mineral powder will fall through the filter screen on the filter screen frame 7 and slide quickly into the drawer box 18 for collection through the inclined surface on the inclined block 16, while the coarser mineral powder will remain inside the filter screen frame 7. When it is necessary to clean the mineral powder inside the filter screen frame 7, simply remove the filter screen frame 7 according to the above steps. It is simple, convenient and practical.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
