When the transmission rod 20 rotates, the third fixed block 21 will be driven to rotate synchronously. When one end of the third fixed block 21 rotates to the top of the screen plate 24, the screen plate 24 will be squeezed to move downward, and the screen plate 24 will be driven to move downward along the surface of the guide rod 23, and the reset spring 25 will be squeezed to shrink.

[0026] Working principle: When grinding is required, calcium oxide is first placed into the hopper 10, and the baffle 18 at the top of the hopper 10 can prevent the calcium oxide from falling into the first gear 14 and the second gear 15, and the first motor 11 is started to drive the first grinding roller 12 and the first gear 14 to rotate, and the other end of the first grinding roller 12 rotates along the inside of the first fixed block 13. When the first gear 14 rotates, it drives the second gear 15 and the second grinding roller 16 to rotate synchronously, and both ends of the second grinding roller 16 rotate along the inside of the second fixed block 17. When the first grinding roller 12 and the second grinding roller 16 rotate at the same time, the calcium oxide in the hopper 10 will be ground, and the calcium oxide after grinding will fall into the inside of the device body 1 for grinding.

[0027] When screening is performed, the ground calcium oxide inside the feed hopper 10 will fall to the top of the screening plate 24 inside the device body 1, and the second motor 19 will be started to drive the transmission rod 20 to rotate. When the transmission rod 20 rotates, the third fixed block 21 will be driven to rotate synchronously. When one end of the third fixed block 21 rotates to the top of the screening plate 24, the screening plate 24 will be squeezed to move downward, driving the screening plate 24 to move downward along the surface of the guide rod 23 and squeezing the reset spring 25 to contract. When one end of the fixed block 21 is separated from the surface of the screening plate 24, the screening plate 24 is driven to rebound upward under the rebound force of the reset spring 25. Repeating this action will cause the screening plate 24 to be in a state of shaking up and down, thereby screening the calcium oxide after grinding at the top of the screening plate 24. The screened calcium oxide will fall into the collecting box 28, and then the collecting box 28 will be pulled outward, driving the collecting box 28 to move outward along the inside of the fifth fixed block 27 until the collecting box 28 is completely pulled out for screening.

[0028] When the screening plate needs to be removed for later cleaning, first rotate the limit bolt 26 to drive the bottom end of the limit bolt 26 to rotate along the inside of the guide rod 23 and move outward until the limit bolt 26 is completely separated from the inside of the guide rod 23, and then lift the screening plate 24 upward to drive the screening plate 24 to move outward along the surface of the guide rod 23 until it is completely separated from the surface of the guide rod 23.
