Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, specifically a diamond multi-stage uniform screening device. Background Technology
[0002] Diamond is a mineral composed of pure carbon, possessing extremely high hardness and excellent physicochemical properties. Its chemical stability and exceptional hardness are well-known. Mined diamonds are typically crushed using crushing mechanisms, and the resulting crushed diamond material is then screened for finer particles.
[0003] When using a screening device to process diamond crushed material, the amount of material that can be poured into the inspection sieve is limited. Too much material will prevent the inspection sieve from tumbling evenly, thus preventing the extraction of more basic particles. Only a small amount of material can be added per screening, making the screening of diamond crushed material time-consuming, labor-intensive, and wasteful. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This diamond multi-stage uniform screening device, by setting up a uniform distribution device, installs a rectangular rod inside the screen. When the screen vibrates, it drives the cylinders on both sides of the rectangular rod to move. The cylinders are pulled by springs, which drive the scraper at the bottom of the rotating shaft to move back and forth at the bottom of the screen, pushing the material to move. This allows the material to move left and right inside the screen, preventing it from accumulating on one side of the screen and affecting the quantity and efficiency of the material entering the next layer.
[0017] 2. This diamond multi-stage uniform screening device uses a coil spring to allow the rotating shaft and scraper to move when the cylinder moves, pushing the material. The rotating shaft can rotate to a certain extent and the coil spring can deform. When the material on one side of the scraper decreases, the coil spring returns to its original shape, which can drive the rotating shaft and scraper to rotate and further disperse the material, thus improving the effect of the uniform screening device.
[0018] 3. This diamond multi-stage uniform screening device, by setting an auxiliary device, can install the rectangular rod inside the screen by pressing the two ends of the rectangular rod against the protrusions on both sides of the inner wall of the screen and forcefully pushing the rectangular rod to move on the arc surface of the protrusions, squeezing the two ends of the rectangular rod between the protrusions and the locking blocks.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0026] like Figure 1-5As shown, this utility model provides a technical solution: a diamond multi-stage uniform sieving device, including a base 1, a drive motor 4 is provided on one side of the top of the base 1, the drive motor 4 controls the rotation of the eccentric shaft inside the base 1 to cause the chassis 5 to vibrate, the chassis 5 is provided on the top of the base 1, an electric push rod 6 is provided on the top of the chassis 5, the output rod of the electric push rod 6 is provided with a base 7, rotating blocks are provided on both sides of the base 7, the base 7 slides on the rods on both sides of the surface of the chassis 5, a plurality of screens 8 are provided at the bottom of the base 7, the aperture size of each screen 8 is from large to small from top to bottom, the top of the top screen 8 is provided with a top cover 9, an electric telescopic rod 11 is provided on one side of the top of the chassis 5, and the output rod of the electric telescopic rod 11 is rotatably connected to a striking rod. 10. One end of the striking rod 10 is rotatably connected to one side of the top of the base 5. An equalizing device 2 is installed inside the screen 8 with the aid of an auxiliary device 3. The equalizing device 2 includes a rectangular rod 21, with several round rods 22 fixedly connected to both sides of the rectangular rod 21. A cylinder 23 is slidably connected to the outer surface of the round rods 22. A spring 24 is installed at one end of the cylinder 23, and both ends of the spring 24 are fixedly connected to one end of the cylinder 23 and one side of the rectangular rod 21, respectively. A rotating shaft 25 is rotatably connected to one end of the cylinder 23, and a scraper 26 is fixedly connected to the bottom end of the rotating shaft 25. By setting the scraper 26, when using the screening device, the screens 8 are stacked upwards according to their aperture size from smallest to largest. The remaining screens 8, excluding the bottom screen 8, are then evenly distributed using the auxiliary device 3. In the sub-device 2, diamond crushed material is then added to the top layer of the screen 8. The top cover 9 is then placed on the base 7, and the screen 8 is placed on the base 7. The rotating blocks on both sides of the base 7 are rotated to fix the position of the screen 8. The electric push rod 6 is operated to control the base 7 to rise so that the top of the top cover 9 contacts the tops of the rods on both sides of the base 5. The drive motor 4 and the electric telescopic rod 11 are operated. The drive motor 4 drives the eccentric shaft inside the base 1 to rotate, causing the base 5 to vibrate. At the same time, the electric telescopic rod 11 extends and retracts, causing the striking rod 10 to rotate on one side of the top of the base 5 to strike the top cover 9. During the vibration of the screen 8, the cylinders 23 on both sides of the rectangular rod 21 will slide on the outer surface of the round rod 22 to stretch the spring 24, or the tension of the spring 24 will pull the cylinders 23 towards the round rod 22, causing the rotation to... The scraper 26 at the bottom of shaft 25 moves back and forth on the bottom surface of screen 8, pushing the diamond fragments inside screen 8 back and forth. After screening, the operation of drive motor 4 and electric telescopic rod 11 is stopped, the electric push rod 6 is operated to retract and control base 7 to descend, and then the rotating blocks on both sides of base 7 are rotated to release the position fixation of screen 8. Screen 8 is removed in sequence, and the graded diamond fragments inside screen 8 are poured out. By setting up equalization device 2, and by installing rectangular rod 21 inside screen 8, when screen 8 vibrates, it drives the cylinders 23 on both sides of rectangular rod 21 to move. Spring 24 pulls cylinder 23, which drives the scraper 26 at the bottom of shaft 25 to move back and forth at the bottom of screen 8, pushing the material to move left and right inside screen 8.It will not accumulate on one side of screen 8, affecting the quantity and efficiency of material entering the next layer.
[0027] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the inner diameter of spring 24 is slightly larger than the diameter of round rod 22. Spring 24 is located outside round rod 22. When the cylinder 23 moves and causes spring 24 to deform, spring 24 will move outside round rod 22. Round rod 22 can reinforce the internal shape of spring 24 and avoid lateral twisting of spring 24 as much as possible, which would affect normal use. Auxiliary block 27 is fixedly connected to the bottom end of scraper 26. The outer surface of auxiliary block 27 is triangular in shape, and the two sides of auxiliary block 27 are narrow. By setting auxiliary block 27, scraper 26 can more easily scrape up and move material in screen 8 when it moves back and forth inside screen 8.
[0028] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, a coil spring 28 is provided at the top of the rotating shaft 25. The two ends of the coil spring 28 are fixedly connected to one side of the rotating shaft 25 and one side of the inner wall of the cylinder 23, respectively. By setting the coil spring 28, when the cylinder 23 moves, it drives the rotating shaft 25 and the scraper 26 to move and push the material, the rotating shaft 25 can rotate to a certain extent and the coil spring 28 will deform. When the material on the scraper 26 side decreases, the coil spring 28 returns to its original shape and can drive the rotating shaft 25 and the scraper 26 to rotate to further disperse the material and improve the effect of the equalization device 2. A through groove 29 is opened on the outer surface of the rotating shaft 25. A U-shaped rod 210 is fixedly connected to one side of the bottom end of the cylinder 23. The outer surface part of the U-shaped rod 210 is located inside the through groove 29. By setting the U-shaped rod 210, the rotation angle of the rotating shaft 25 can be limited, so as to avoid the rotating shaft 25 rotating too much when there is too much material on the scraper 26 side, which would damage the coil spring 28.
[0029] Specifically, such as Figure 1-5 As shown, the auxiliary device 3 includes a locking block 31 and a protrusion 32. The locking block 31 and the protrusion 32 are fixed on both sides of the inner wall of the screen 8. The protrusion 32 is located above the rectangular block. One edge of the protrusion 32 is arc-shaped. When installing the equalizing device 2, the two ends of the rectangular rod 21 are pressed against the protrusions 32 on both sides of the inner wall of the screen 8. The rectangular rod 21 is pushed to move on the arc-shaped surface of the protrusion 32 and squeeze the two ends of the rectangular rod 21 between the protrusion 32 and the locking block 31 to install the rectangular rod 21 inside the screen 8. The top of the rectangular rod 21 is fixedly connected to a groove block 33. The groove block 33 has grooves 34 on both sides. By pinching the grooves 34 on both sides of the groove block 33, it is easier to pull the groove block 33 to pull the two ends of the rectangular rod 21 out from between the protrusion 32 and the locking block 31.
[0030] The working principle of this utility model is as follows:
[0031] S1. When using the screening device, stack the screens 8 in order of increasing aperture size. Inside the remaining screens 8 (excluding the bottom screen 8), place the two ends of the rectangular rod 21 against the protrusions 32 on both sides of the inner wall of the screen 8. Push the rectangular rod 21 forcefully to move it on the arc surface of the protrusion 32, squeezing the two ends of the rectangular rod 21 between the protrusion 32 and the locking block 31. Install the rectangular rod 21 inside the screen 8. Then add diamond crushed material into the top screen 8, cover it with the top cover 9, place the screen 8 on the base 7, and rotate the rotating blocks on both sides of the base 7 to fix the position of the screen 8.
[0032] S2. Operate the electric push rod 6 to control the base 7 to rise, so that the top of the top cover 9 contacts the top of the rods on both sides of the chassis 5. Operate the drive motor 4 and the electric telescopic rod 11. The drive motor 4 drives the eccentric shaft inside the base 1 to rotate, causing the chassis 5 to vibrate. At the same time, the electric telescopic rod 11 extends and retracts, causing the striking rod 10 to rotate on one side of the top of the chassis 5 to strike the top cover 9. During the vibration of the screen 8, the cylinders 23 on both sides of the rectangular rod 21 will slide on the outer surface of the round rod 22 to stretch the spring 24, or the pulling force of the spring 24 will pull the cylinder 23 to move towards the round rod 22, so that the scraper 26 at the bottom of the rotating shaft 25 moves back and forth on the bottom surface of the screen 8, pushing the diamond fragments inside the screen 8 back and forth. After screening is completed, stop the operation of the drive motor 4 and the electric telescopic rod 11. Operate the electric push rod 6 to retract and control the base 7 to descend. Then rotate the rotating blocks on both sides of the base 7 to release the position fixation of the screen 8. Remove the screen 8 in sequence and pour out the graded diamond fragments inside the screen 8.
