[0035] In a preferred embodiment, please refer to Figures 1 to 2 The bottom of the screening component is equipped with a drive component, which consists of a first cylinder 14 and a connecting plate 15.

[0036] In this embodiment, a viewing window and a discharge port are installed on the side of the crushing chamber 2, and the first cylinder 14 is electrically connected to the control panel via wires.
[0037] In this embodiment, when the operator observes through the viewing window that there is a lot of limestone piled up on the top surface of the screen 12, the first cylinder 14 is controlled to drive the top ball to move downward, thereby driving the connecting plate 15 and the screening mechanism to rotate downward, so that the limestone is discharged from the discharge port of the crushing chamber 2 along the top surface of the screen 12 and the second guide plate 13.
[0038] In a preferred embodiment, please refer to Figures 1 to 4 A feeding mechanism is provided on the top surface of the workbench 1. The feeding mechanism consists of a second cylinder 16, a material container 17, an L-shaped plate 18, a third guide plate 19, a guide rod 21, and a return spring 22. The second cylinder 16 is fixedly installed on the top surface of the workbench 1. The material container 17 is fixedly installed on the top surface of the output end of the second cylinder 16. The top surface of the material container 17 and the side near the crushing chamber 2 are both open. An L-shaped plate 18 is slidably connected to the side of the material container 17. The L-shaped plate 18 includes a horizontal part and a vertical part. The front and rear sides of the vertical portion of the L-shaped plate 18 are slidably connected to the material container 17. Multiple guide rods 21 and a return spring 22 are fixedly installed on the bottom surface of the material container 17. The end of the return spring 22 away from the material container 17 is fixedly connected to the top surface of the horizontal portion of the L-shaped plate 18. A guide groove adapted to the guide rod 21 is provided through the top surface of the horizontal portion of the L-shaped plate 18. The guide rod 21 passes through the guide groove and slides through the L-shaped plate 18. A third guide plate 19 is fixedly installed on the side of the crushing chamber 2.
[0039] In this embodiment, the second cylinder 16 is electrically connected to the control panel via a wire, and the side of the third guide plate 19 away from the crushing chamber 2 is on the same plane as the side of the vertical portion of the L-shaped plate 18 away from the crushing chamber 2.
[0040] In this embodiment, the material container 17, in conjunction with the L-shaped plate 18, can collect the limestone discharged along the screen 12 and the second guide plate 13. By controlling the second cylinder 16 to drive the material container 17 to move upward, the limestone inside the material container 17 can be transported to the highest point. When the third guide plate 19 contacts the L-shaped plate 18, it prevents the L-shaped plate 18 from moving upward. The return spring 22 is extended, and the material container 17 continues to move upward relative to the L-shaped plate 18. This allows the limestone inside the material container 17 to enter the top of the crushing chamber 2 along the top surface of the L-shaped plate 18 and the third guide plate 19, thereby enabling repeated crushing of limestone with larger particle sizes and facilitating thorough crushing of the limestone.
[0041] The working principle of this utility is as follows:
[0042] When the device is in use, the servo motor 3 drives the drive gear 4 to rotate, the drive gear 4 drives the first driven gear 5 to rotate, the first driven gear 5 drives the first rotating rod 7 and the first crushing roller 8 to rotate, the first driven gear 5 drives the second driven gear 6 to rotate, the second driven gear 6 drives the second rotating rod 9 and the second crushing roller 10 to rotate, and the limestone raw material is fed into the crushing chamber 2 from the top. The limestone can be crushed by the first crushing roller 8 and the second crushing roller 10 rotating in opposite directions. The limestone crushed by the crushing mechanism falls on the top surface of the screen 12. The limestone that meets the particle size requirements passes through the screen holes and enters the collection box 20 below for collection. The larger limestone particles accumulate on the top surface of the screen 12.
[0043] When the staff observes through the viewing window that there is a lot of limestone accumulated on the top surface of the screen 12, they control the first cylinder 14 to move the top ball downwards, thereby causing the connecting plate 15 and the screening mechanism to rotate downwards, so that the limestone is discharged from the discharge port of the crushing chamber 2 along the top surface of the screen 12 and the second guide plate 13. The material box 17, together with the L-shaped plate 18, can collect the limestone discharged along the screen 12 and the second guide plate 13.
[0044] After the material collection box 17, in conjunction with the L-shaped plate 18, completes the collection of limestone, the first cylinder 14 is controlled to drive the screening mechanism to rotate upwards back to its original position, and the second cylinder 16 is controlled to drive the material collection box 17 to move upwards, which can transport the limestone inside the material collection box 17 to the highest point. When the third guide plate 19 contacts the L-shaped plate 18, it prevents the L-shaped plate 18 from moving upwards further, and the return spring 22 is extended. The material collection box 17 continues to move upwards relative to the L-shaped plate 18, so that the limestone inside the material collection box 17 can enter the top of the crushing chamber 2 along the top surface of the L-shaped plate 18 and the third guide plate 19, so as to realize repeated crushing of limestone with larger particle size, which facilitates the thorough crushing of limestone.
[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
