[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0020] Example 1
[0021] The utility model provides a particle size sorting device for limestone ore, a raw material for machine-made sand production, such as Figures 1 to 4As shown in the figure, it includes a frame 1. On one side of the top end of the frame 1, a separator 5 is fixedly installed. On the top of one end of the separator 5, a hopper 4 is fixedly installed. On one side of the separator 5, a vibration device 9 is fixedly installed. Inside the separator 5, a screening plate 8 is movably connected. The screening plate 8 is fixedly installed at one end of the vibration device 9. At the top end inside the separator 5, an electric telescopic rod 7 is fixedly installed. The bottom end of the electric telescopic rod 7 is fixedly connected to a lifting plate 11. At the bottom end of the lifting plate 11, a number of fixed rods 14 are fixedly installed. At the bottom end of the fixed rods 14, a punch 13 is fixedly installed. At both ends of the lifting plate 11, partition plates 12 are fixedly connected.
[0022] As Figure 1 and Figure 3 shown in the figure, inside the frame 1, a first discharge port 2 is installed at the position of the bottom end of the separator 5, and a second discharge port 3 is installed at the position of one end of the separator 5. Through the first discharge port 2 and the second discharge port 3, ores with different particle sizes can be effectively classified and discharged.
[0023] As Figure 1 and Figure 3 shown in the figure, inside the frame 1, baffles 15 are movably connected at the positions of the first discharge port 2 and the second discharge port 3 respectively. At one end of the baffle 15, a threaded rod 17 is fixedly installed. The outer side of the threaded rod 17 is rotationally connected with a threaded sleeve 16 by threads, and the threaded sleeve 16 is rotationally connected to the inside of the frame 1. Inside the frame 1, limit grooves 18 are respectively opened at the positions of one end of the first discharge port 2 and the second discharge port 3. Inside the limit grooves 18, positioning plates 6 are movably installed. One end of the positioning plate 6 far from the baffle 15 is fixedly connected to a spring 10, and the spring 10 is fixedly installed inside the frame 1. The combination of the positioning plate 6 and the spring 10 can prevent ores from entering the inside of the limit grooves 18 when the baffle 15 is not in use, thus affecting the normal use of the baffle 15.
[0024] As Figure 1 and Figure 2 shown in the figure, the number of screening holes opened on the fixed rods 14 is the same as that on the screening plate 8. The diameter of the fixed rods 14 is smaller than the diameter of the screening holes opened on the screening plate 8. The center lines of the screening holes opened on the fixed rods 14 and the screening plate 8 coincide with each other, which can effectively clean each screening hole, prevent the screening holes from being blocked, and maintain the screening efficiency of the screening plate 8.
[0025] As Figure 1 and Figure 2 shown in the figure, the shape of the punch 13 is conical and the diameter of the top end is larger than that of the bottom end. The punch 13 will not exert a large-area force on the ore, preventing the ore from being squeezed and bounced to damage the separator 5, and can also crush the ore stuck in the screening holes.
[0026] As Figure 1 and Figure 3As shown, both the limit groove 18 and the guide groove 19 have slopes with a slope of 45°. The slope design helps the ore to slide smoothly and prevents blockage inside the limit groove 18 and the guide groove 19.
[0027] Working principle: During the actual use of this device, the raw limestone ore is poured into the hopper 4. The raw limestone ore falls from the hopper 4 and enters the top of the screening plate 8 inside the separator 5. Then, the vibration device 9 is started. The vibration device 9 drives the screening plate 8 to vibrate violently. The vibration of the screening plate 8 drives the displacement of the raw limestone ore. When the raw limestone ore passes through the screening holes opened on the screening plate 8, the limestone ore will be sorted by particle size. The limestone ore smaller than the diameter of the screening holes will fall and be discharged from the first discharge port 2. The limestone ore larger than the diameter of the screening holes will be displaced to one end of the screening plate 8 and fall and be discharged from the second discharge port 3. When there is ore stuck in the screening holes opened on the screening plate 8, the electric telescopic rod 7 is started. The electric telescopic rod 7 drives the lifting plate 11 to move downward. The lifting plate 11 drives the fixed rod 14 to move downward. The fixed rod 14 drives the punch 13 to move downward. The punch 13 can clean the ore stuck inside the screening holes, can dredge the screening holes to prevent ore blockage, maintain the screening efficiency, enhance the reliability of the sorting equipment, and can also reduce the workload of manual cleaning due to screening hole blockage and reduce the labor intensity.
[0028] Then, when the collection box placed at the bottom of the first discharge port 2 finishes collecting, the threaded sleeve 16 is rotated. The rotation of the threaded sleeve 16 drives the internal threaded rod 17 to move. The movement of the threaded rod 17 drives the baffle 15 to move. Both sides of the baffle 15 move along the guide groove inside the frame 1. Then, one end of the baffle 15 will contact the positioning plate 6. As the baffle 15 moves, it will slowly squeeze the spring 10 at one end of the positioning plate 6 until it snaps into the limit groove 18. At this time, the baffle 15 seals the first discharge port 2. Then, the collection box is replaced. The second discharge port 3 uses the same method to replace the collection box, which can avoid the scattering of ore caused by replacing the collection box, reduce material loss, eliminate the need to clean the ore on the ground, and reduce the extra labor and time required to clean the scattered ore.
[0029] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
