When the iron impurities need to be taken out, the electromagnet 65 is turned off by the controller. The electromagnet 65 The impurities no longer have adsorption force, so that the iron impurities can be discharged from the discharge cover, the screen 42 screens out unqualified materials, and the fixed cover 22 can be opened to take them out. When it is necessary to replace the screen 42 of the same specification but different aperture size, the fixed cover 22 is opened, and then the baffle 56 is pulled upward, and the baffle 56 drives the limit plate 47 to move upward through the connecting rod 52, and the limit plate 47 squeezes the buffer spring 48 and the telescopic rod 46 to move, so that the limit plate 47 and the screen 42 are separated, so that the baffle 56 moves to the high The iron block 54 is positioned at the position of the iron block 54, and then the iron block 54 is rotated to separate the iron block 54 and the magnet 55, so that the iron block 54 rotates to the bottom of the baffle 56, thereby supporting the limit baffle 56. At this time, the screen 42 can be pulled out forward, and when the required screen 42 is replaced, the replaced screen 42 is placed on the top of the protrusion 44 again, and then the iron block 54 and the baffle 56 are separated, and the restoring elastic force of the buffer spring 48 is used to make the limit plate 47 and the screen 42 in close contact.
