The working principle is as follows: in the initial state, the four reinforcing bottom ground supporting pieces 17 are in a ground supporting state, the four grounding wheels 16 are suspended in the air, the reinforcing motor 19 is started to control the rotation of the middle threaded rod 18, the heights of the four reinforcing bottom ground supporting pieces 17 are adjusted, the four grounding wheels 16 fall to the ground, the motion direction of the grounding wheels 17 is controlled, and the ore fragment screening and cleaning device is moved to a station. The reinforcing bottom end grounding piece 17 is then grounded by controlling the reinforcing motor 19, so that the standby state is achieved. The water jet means 22 is then turned on to introduce the mineral pieces to be screened and cleaned into the coarse screen 24 and the central motor 42 and the up-and-down pushing means 43 are turned on, the rotation of the central drive rotation shaft 44 will drive the rotation of the top drive rotation shaft 51, the vibration drive means 52 and the bottom drive rotation shaft 54 under the drive of the central motor 42. The mixture of ore fragments originally containing coarse impurities is first screened out by the rotation of the top driving screw 51 in the coarse screen 24, the large ore fragments and the like fall into the lower large fragment screen 31, and the large stone blocks and the like reach the coarse screen outlet 231 through the flap door 33 and are discharged. Rotation of the vibratory drive 52 causes the vibratory drive element 523 to which the vibratory drive spring 522 is attached to continually compress the inside upper edge of the large fragment screen 31 due to dimensional constraints, causing the large fragment screen 31 to vibrate obliquely from side to side. Due to the up-and-down movement of the up-and-down pushing device 43, the fragments are discharged to push the circular ring 53 to act on the inner side of the bottom of the large fragment screen 31 back and forth, so that the edge of the large fragment screen 31 is inclined, the loose-leaf door 33 is opened, and the large ore fragments fall into the large fragment delivery position 232 through the loose-leaf door 33, so that the purpose of screening the large ore fragments is achieved. The remaining ore fragments to be screened fall into the middle fragment screen 32, and as the principle for screening large ore fragments is the same, under the rotation of the central driving rotating rod 44, the vibration driving device 52 can enable the middle fragment screen 32 to vibrate obliquely from side to side, and the up-and-down movement of the up-and-down pushing device 43 can enable the fragment unloading pushing ring 53 to act on the inner side of the bottom of the middle fragment screen 32 back and forth, so that the edge of the middle fragment screen 32 is inclined, and the middle ore fragments pass through the loose-leaf door 33 to be screened out. Remaining small ore fragment and impurity such as fine sand fall into the little fragment department of receiving 25 of bottom, drive the spiral rod 54 at the bottom and move down, little volume object such as silt gets into little fragment department of transporting 234 through loose-leaf door 33, because little fragment department of transporting 234 designs into the screen cloth, tiny impurity such as silt just spills from the screen cloth, and little ore fragment just drops from the exit with this and selects little ore fragment. So far, the ore fragments containing various impurities are screened, classified and cleaned.

It should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
