[0032] Furthermore, a first spring 413 is arranged between the screen plate 412 and the mounting frame 411, the cam 416 is in contact with the bottom of the screen plate 412, the screen plate 412 is arranged at an angle, and a first leakage trough is opened at the corresponding position of the outer frame 1 and the left side of the screen plate 412 to facilitate the shaking of the set screen plate 412 to screen the crushed iron ore.

[0033] Furthermore, the pushing component 42 includes a first pulley 421, which is fixedly mounted on the output shaft of the drive motor 414. A reciprocating screw 422 is rotatably mounted inside the outer frame 1, and a second pulley 423 is fixedly mounted outside the reciprocating screw 422. A synchronous belt 424 is installed on the external transmission of the first pulley 421 and the second pulley 423. A movable block 425 is movably mounted outside the reciprocating screw 422. A connecting disk 426 is provided inside the movable block 425, and a connecting block 427 is fixedly mounted on the bottom of the connecting disk 426. A scraper 428 is fixedly mounted on the bottom of the movable block 425, which facilitates the pushing of the iron ore particles at the bottom end of the outer frame 1 and facilitates the discharging work.

After the crushing and screening work is completed, the handle 55 can be pulled to take out the collection frame 54 and the collected dust can be uniformly processed. As the drive motor 414 rotates, the first pulley 421 can be rotated synchronously. Under the action of the synchronous belt 424, the second pulley 423 can be rotated to rotate the reciprocating screw 422 so that the connecting block 427 can move back and forth along the groove direction of the reciprocating screw 422. Under the action of the connecting disk 426, the movable block 425 can be reciprocated, thereby driving the scraper 428 to reciprocate to push the crushed iron ore particles inside the outer frame 1 and guide them out from the second leakage chute.
