[0029] The vibration dust removal assembly 7 includes a cam 702, with a mounting groove seat 8 attached to the top of the cam 702. One side of the cam 702 is connected to a connecting shaft 710. The top of the mounting groove seat 8 is connected to the bottom of the sieve basket 2. Two sliding grooves 706 are provided on one side of the support frame 1. A sliding sleeve 707 is slidably connected within the sliding grooves 706. One side of the sliding sleeve 707 is connected to one side of the sieve basket 2. Two through grooves are provided on one side of the support frame 1, and dust removal fans 703 that can rotate freely are arranged within the through grooves. A fixed sliding rod 705 is connected inside the sliding groove 706. The fixed sliding rod 705 is slidably connected to the sliding sleeve 707. A return spring 704 is sleeved on the outer surface of the fixed sliding rod 705. The two ends of the return spring 704 are respectively connected to one side of the sliding sleeve 707 and one side of the inner wall of the sliding groove 706. A driving motor 701 is fixedly installed on one side of the support frame 1 through a mounting plate. One end of the connecting shaft 710 extends to the other side of the support frame 1 and is connected to one end of the output shaft of the driving motor 701. One side of the dust removal fan 703 is connected to a rotating shaft. A mounting rod is connected within the through groove. The rotating shaft is rotatably connected to the mounting rod through a bearing. Transmission wheels 709 are connected to the outer surfaces of both the rotating shaft and the connecting shaft 710, and a transmission belt 708 is connected between the three transmission wheels 709. By setting the vibration dust removal assembly 7, the driving motor 701 drives the cam 702 to rotate. The cam 702, in cooperation with the return spring 704, drives the sliding sleeve 707 to perform reciprocating motion, causing the sieve basket 2 to vibrate reciprocally in the vertical direction, thereby accelerating the screening efficiency of the ore raw materials inside the sieve basket 2. Moreover, the driving motor 701 drives the dust removal fan 703 to rotate through the connecting shaft 710, transmission wheels 709, transmission belt 708, and rotating shaft. The dust removal fan 703 takes out the dust particles during the falling process to the other side of the support frame 1 through the airflow, and by the action of the wind, the content of dust impurities in the screened ore is reduced.

[0030] The adjustment assembly 3 includes a movable sieve plate 301. The movable sieve plate 301 is slidably connected between two mounting groove seats 8. One side of the sieve basket 2 is rotatably connected to an adjustment lead screw 304. A lead screw seat 303 is threadedly connected to the outer surface of the adjustment lead screw 304. The bottom of the lead screw seat 303 is connected to one side of the movable sieve plate 301. One end of the adjustment lead screw 304 is connected to a knob 302. A discharge hopper 4 is connected to one side of the sieve basket 2. A first collection box 5 is provided at the bottom of one side of the discharge hopper 4. A second collection box 6 is provided at the bottom of the sieve basket 2. By setting the adjustment assembly 3, the staff drives the movable sieve plate 301 to move within the two mounting groove seats 8 through the knob 302, adjustment lead screw 304, and lead screw seat 303, so that the sieve holes between the sieve basket 2 and the movable sieve plate 301 are mutually blocked, enabling the size of the sieve holes to be changed, thereby meeting the screening requirements of different ores.

[0031] Working principle: When in use, the staff conveys the ore raw materials into the screening basket 2. At this time, two driving motors 701 are started. The driving motor 701 drives the cam 702 to rotate the ring. The cam 702 drives the mounting groove seat 8 to move. The mounting groove drives the screening basket 2 to move upward. At the same time, the reset spring 704 drives the sliding sleeve 707 to perform a reset movement. The sliding sleeve 707 drives the screening basket 2 to perform a reset movement, so that the screening basket 2 vibrates reciprocally in the vertical direction. The screening basket 2 drives the ore raw materials inside to vibrate, and screens the ore raw materials through the screening basket 2, so that ores of different sizes fall into the first collection box 5 and the second collection box 6 respectively. At the same time, the driving motor 701 drives the connecting shaft 710 to rotate. The connecting shaft 710 drives the transmission wheel 709 to rotate. The transmission wheel 709 drives the transmission wheels 709 on both sides to rotate through the transmission belt 708. The transmission wheel 709 drives the rotation through the rotating shaft. The rotating shaft drives the dust removal fan 703 to rotate. The dust removal fan 703 takes out the dust particles in the falling process through the air flow to the other side of the support frame 1, achieving the dust removal effect. When the required ore sizes are different, the staff rotates the knob 302. The knob 302 drives the adjusting lead screw 304 to rotate. The adjusting lead screw 304 drives the lead screw seat 303 to move. The lead screw seat 303 drives the movable sieve plate 301 to move in the two mounting groove seats 8, so that the sieve holes between the screening basket 2 and the movable sieve plate 301 are mutually blocked, thereby changing the screening of the falling ore sizes.
