[0037] Working principle: Before using this ore screening device with an anti-blocking structure, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 -Figure 5 As shown, first, pour the ore into the screening frame 102 from the blanking hopper 103. Drive the propeller 114 to rotate through the cleaning rod 113. By utilizing the cooperation between the propeller 114 and the screening frame 102, the ore can be slowly transported into the screen 109 for screening.

[0038] Secondly, start the drive motor 105 to drive the driving wheel 106 to rotate. By utilizing the meshing effect between the driving wheel 106 and the first driven wheel 107, the screen 109 can be driven to rotate forward, so as to screen the ore. At the same time, by utilizing the meshing effect between the driving wheel 106 and the second driven wheel 111, the roller shaft 112 and the cleaning rod 113 can be driven to rotate.

[0039] Then, start the negative pressure pump 206 to quickly collect the dust near the dust suction hood 202, so as to avoid the escape of dust and pollution of the surrounding environment. By utilizing the filtering effect of the filter element 203, the dust in the air can be excluded. The air is discharged from the negative pressure pump 206, and the dust falls into the collection hopper 205, so as to collect the dust. When it is necessary to clean the filter element 203, start the pulse air pump 204. The pulse formed by the compressed air of the pulse air 204 can clean the surface of the filter element 203 to avoid blockage of the filter element 203.
