The two eccentric blocks 24 are rotatably connected to the lower end of the connecting handle 18. The upper end of the connecting handle 18 is rotatably connected to the fixed block 19 through a connecting pin 17. The upper end of the fixed block 19 is fixedly connected to the movable tube 20. The bottom of the supporting platform 12 is fixedly connected to a fixed tube 22. The movable tube 20 is slidably connected to the fixed tube 22. The bottom of the supporting platform 12 is fixedly connected to a fixed rod 23. The lower end of the fixed rod 23 extends into the interior of the movable tube 20. A compression spring 21 is sleeved on the fixed rod 23. The compression spring 21 is located between the lower end of the fixed rod 23 and the inner top wall of the movable tube 20.

[0018] It should be noted that, in the present invention, the first fixing plate 10 and the second fixing plate 11 are installed with the same structure and usage.

[0019] In order to prevent the ore from falling during transportation after screening, first protective plates 7 are fixedly connected to both sides of the first material plate 6 , and second protective plates 9 are fixedly connected to both sides of the second material plate 8 .

[0020] In order to reduce the wear of both ends of the fixing rod 23 during the vibration process, reduce the generation of noise and provide buffering, buffer rubber plugs are connected to both ends of the fixing rod 23.

[0021] In order to facilitate the fixing of the door panel structure that can be lifted and lowered and realize the door panel lifting function, the vibration cabin 1 is provided with a first discharge port and a second discharge port. The first discharge port is located at the lower end of the inclined plate 5, and the second discharge port is located at the lower end of the screen plate 4. The first discharge port and the second discharge port are fixedly connected to the outside of the first discharge port and the second discharge port respectively. In order to realize the door panel lifting function, the first fixed plate 10 and the second fixed plate 11 are fixedly connected on both sides of the bottom end with slide rails 23, and the slide rails 23 are slidably connected to the door panel 27. The upper end of the door panel 27 is hinged to one end of the T-shaped rod 28, and the other end of the T-shaped rod 28 is fixedly connected to the U-shaped rod 29, and the U-shaped rod 29 is rotatably connected to the upper part 32 of the block through the connecting shaft 31. The first fixed plate 10 and the second fixed plate 11 are fixedly connected with a fixed pile 30, and the lower end of the block 32 is rotatably connected to the fixed pile 30 through the shaft, and the shaft is transmission connected to the output end of the motor 33.

[0022] In order to regulate the moving path of the vibration spring 13 and enhance the stability of the feeding system, a support column 34 is fixedly connected to the bottom plate 14 , and a space for accommodating the vibration spring 13 is opened inside the support column 34 .

[0023] The working process of this embodiment is as follows:

[0024] The limestone ore after preliminary crushing enters the vibrating chamber 1 through the feed port 2, and the rotating disk 15 is rotated by electricity, and the eccentric block 24 is rotated by the rotating shaft 16. The eccentric block 24 is connected to the rotating shaft 16 and the connecting handle 18 at two different positions, so that the connecting handle 18 performs eccentric movement, thereby driving the fixed block 19 and the movable tube 20 to perform reciprocating translational movement. The movement trajectory of the movable tube 20 is always within the range of the fixed tube 22. When the movable tube 20 moves downward, the compression spring 21 is squeezed and moves along the internal space of the support column 34. When the movable tube 20 moves upward, the compression spring 21 rebounds. Under the action of the vibration spring 13, vibration is formed on the supporting platform 12 and the vibrating chamber 1 connected to the top of the supporting platform 12. Through vibration, the limestone ore that meets the specifications in the vibrating chamber 1 passes through the screening of the screen plate 4 and falls on the inclined plate 5, while the limestone ore that does not meet the specifications continues to stay. Above the sieve plate 4, the motor 33 is then used to rotate the block 32, which rotates upward and drives the U-shaped rod 29, T-shaped rod 28, and door panel 27 upward. When the block 32 reaches the highest point, the motor 33 stops rotating. Under the influence of gravity, the block 32 contacts the upper edge of the first fixed plate 10. At this time, the screened limestone ore leaves the vibrating cabin 1 along the inclined plate 5 and is sent to the next grinding process through the second material plate 8. The same method is used to make the limestone ore that fails to pass the screening leave the vibrating cabin 1 along the sieve plate 4 and return to the crushing process through the first material plate 6. Before a new round of feeding, the motor 33 rotates in the opposite direction, and the block 32 first moves upward to separate from the first fixed plate 10 and then moves downward, driving the U-shaped rod 29, T-shaped rod 28, and door panel 27 downward to complete the closing of the second discharge port 25. The first discharge port is closed in the same way.
