Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ore screening, and particularly relates to an ore coarse screening device for mine stone material exploitation. BACKGROUND

[0002] In the process of ore exploitation, the mine needs to be blasted, so the obtained ores are of different sizes and need to be screened.

[0003] The existing ore coarse screening device needs to use a screening plate (as shown in Figure 1 ) when screening ores. The screening plate is generally inclined, so that the ores can slide downward along the slope, thereby passing through screening holes (as shown in Figure 1 ) of different diameters for screening treatment. However, in the process of ore sliding, small ores are screened first, and large ores are screened again. The relatively large ores may drive the smaller ores to continue to slide, thereby causing the small ores to miss the corresponding screening holes and fall from the large screening holes. This leads to inaccurate screening results. SUMMARY

[0013] As a preferred embodiment of the above technical solution, the height of the baffles protruding from the screening plate gradually decreases from left to right, and the height of the baffles matches the diameter of the corresponding screen holes.

[0014] As a preferred embodiment of the above technical solution, an anti-blocking mechanism is provided at the bottom of the screening plate corresponding to the position of the baffle. The anti-blocking mechanism includes a sliding plate, and a corresponding groove is opened at the bottom of the screening plate. The sliding plate is slidably engaged in the groove. A support plate is provided on the side of the sliding plate near the baffle. Movable rods are evenly and movably installed through the support plate. The number of movable rods is the same as the number of screen holes at the corresponding positions. An anti-blocking head is provided at the top of the movable rod. The anti-blocking head matches the screen hole. An elastic element is sleeved around the movable rod between the anti-blocking head and the support plate. A fixed pulley is installed on the right side of the baffle at the bottom of the screening plate. A traction rope is fixed on one side of the sliding plate. The traction rope is wound around the fixed pulley, and its other end is fixed to one side of the baffle.

[0015] As a preferred embodiment of the above technical solution, a mounting plate is fixed to the right side of the skateboard, a telescopic component three is mounted on the mounting plate, a rocker is passed through the skateboard, the rocker is located inside the skateboard and is rotatably connected to the inner side wall of the skateboard, the top left side of the rocker abuts against the movable rod, and the output end of the telescopic component three abuts against the top right side of the rocker.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The screen plate is set to move and, in conjunction with the telescopic component, the ore on the screen plate shakes, causing the ore piled up to disperse, thereby effectively preventing large ore from dragging smaller ore down and causing them to miss their corresponding screen holes.

[0022] 2. By setting up baffles, small ores can be prevented from continuing to slide down and instead be screened through the screen holes. Larger ores will not be affected by the baffles and will continue to slide down over them. This can prevent the ore blocked by the baffles from accumulating too much and causing the screen holes to become blocked, thus affecting the screening effect. On the other hand, it allows larger ores to slide down first, and when the baffles move down, it is more effective in preventing the larger ores from dragging the smaller ores down with them.

[0024] 4. Equipped with a soft brush and cleaning roller, it can clean the surface of the ore, removing the dirt attached to it, thus ensuring that the ore is in its true size, resulting in more accurate screening results during screening. It also keeps the ore surface clean, facilitating its subsequent use. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] Example

[0033] likeFigures 1-3 As shown;

[0034] The ore roughing device used in the mining process includes a feed hopper 1 with an inlet 11 at the top and an outlet 12 on one side. Ore is poured into the feed hopper 1 through the inlet 11 and discharged through the outlet 12. A guide plate 2 is installed on the feed hopper 1 at the position corresponding to the outlet 12. The guide plate 2 is tilted to the left, so that the ore discharged from the outlet 12 falls onto the guide plate 2 and slides down with the inclination of the guide plate 2. A frame 3 is located on the other side of the guide plate 2. A screening plate 5 is installed on the frame 3 by several support rods 4. The support rods 4 are fixed to one side of the screening plate 5, and the other end of the support rods 4 passes through the side of the frame 3. The screening plate 5 can be moved left and right, thus achieving a shaking effect. Springs are fitted around the support rods 4 corresponding to the frame 3 and the screening plate 5, further enhancing the shaking effect. One side of the guide plate 2 rests on the screening plate 5. Ore sliding down the guide plate 2 falls onto the screening plate 5. The screening plate 5 is tilted to the left and has evenly distributed screen holes 51. The diameter of the screen holes 51 gradually decreases from left to right, allowing smaller ores to pass through the smaller diameter screen holes 51 and larger ores to pass through the larger diameter screen holes 51, thus achieving the screening purpose. Collection frames 31 are evenly distributed on the frame 3, with different positions of the collection frames 31 corresponding to the screen holes at their respective positions. The ore screened through the corresponding sieve hole 51 will enter the corresponding collection frame 31. A telescopic component 6 is installed on one side of the frame 3. This component 6 can be an electric telescopic rod. The output end of the telescopic component 6 passes through the frame 3 and is installed on one side of the screening plate 5. By activating the telescopic component 6, the screening plate 5 is moved to both sides, creating a shaking effect. This causes the ore on the screening plate 5 to shake, dispersing any accumulating ore and effectively preventing larger ore from dragging smaller ore down and causing them to miss their corresponding sieve hole 51. Additionally, the left side of the sieve hole 51 corresponds to the upper part of the screening plate 5... The screen is equipped with a baffle 7, which can prevent the ore from continuing to slide down. In conjunction with the shaking of the screen plate 5, the ore of appropriate size corresponding to the screen hole 51 at the corresponding position can pass through the screen hole 51, thereby achieving the purpose of screening. This also prevents large ore from dragging small ore down. The baffle 7 is L-shaped, and the bottom of the screen plate 5 is equipped with a telescopic component 71. The telescopic component 71 can be an electric telescopic rod. The output end of the telescopic component 71 is fixed at the right angle side of the baffle 7. By activating the telescopic component 71 to retract or extend, the baffle 7 can be moved down to be flush with the surface of the screen plate 5, thereby preventing the remaining ore from continuing to slide down. Similarly, the baffle 7 can be moved up to block the sliding ore.

[0035] Furthermore, soft brushes 21 are evenly provided on the guide plate 2. On the one hand, the soft brushes 21 can reduce the speed at which the ore slides down, thereby reducing the speed at which the ore falls onto the screening plate 5. By reducing the speed at which the ore slides down, it can also effectively prevent large ore from dragging smaller ore down. On the other hand, when the ore comes into contact with the soft brushes 21, the soft brushes 21 can clean off the dirt attached to the surface of the ore, thereby ensuring that the ore is in its true size state, so that the screening results are more accurate during screening. At the same time, it can also keep the surface of the ore clean, which is convenient for its subsequent use.

[0036] Furthermore, the height of several baffles 7 protruding from the screening plate 5 gradually decreases from left to right. The height of the baffles 7 matches the diameter of the corresponding screen holes 51. In this way, larger ore will not be affected by the baffles 7, but will continue to slide down over the baffles 7. This can prevent the ore blocked by the baffles 7 from accumulating too much and causing the screen holes 51 to be blocked, thus affecting the screening effect. On the other hand, it allows the larger ore to slide down first, and when the baffles 7 move down, it can more effectively prevent the large ore from dragging the smaller ore down.

[0037] During screening, the ore falls onto the guide plate 2 through the discharge port 12. The soft brush 21 on the guide plate 2 slows down the ore, reducing its speed as it falls onto the screening plate 5. At the same time, it is blocked by the baffle 7. Larger ore is not affected by the baffle 7 and continues to slide past it. Some of the smaller ore passes through the screen holes 51, while others are squeezed by other larger ore. At this time, the telescopic component 6 causes the screening plate 5 to shake to both sides, dispersing the piled-up ore. This allows the smaller ore to continue to pass through the screen holes 51. When all the smaller ore has passed through the screen holes 51, the telescopic component 71 is activated to move the baffle 7 downward, allowing the other blocked larger ore to continue sliding down and passing through the next screen hole 51 for screening. This process is repeated until the larger ore is finally screened.

[0038] like Figures 2-3 As shown;

[0039] A blocking mechanism 8 is provided at the bottom of the screening plate 5 corresponding to the position of the baffle 7. The blocking mechanism 8 includes a sliding plate 81, and a corresponding groove 52 is provided at the bottom of the screening plate 5. The sliding plate 81 is slidably engaged in the groove 52. A support plate 82 is provided on the side of the sliding plate 81 near the baffle 7. Movable rods 83 are evenly and movably installed through the support plate 82. The number of movable rods 83 is the same as the number of screen holes 51 at the corresponding positions. An anti-blocking head 831 is provided at the top of the movable rod 83. The anti-blocking head 831 matches the screen hole 51 and is used to push out the ore blocked in the screen hole 51, preventing the screen hole 51 from becoming clogged and causing the ore of the corresponding size to become blocked. If the ore misses the corresponding screen hole 51, the screening effect will be reduced. An elastic element 84 is sleeved around the movable rod 83 between the anti-clogging head 831 and the support plate 82. The elastic element 84 can be a spring. A fixed pulley 85 is installed on the right side of the baffle 7 at the bottom of the screening plate 5. A traction rope 851 is fixed on one side of the slide plate 81. The traction rope 851 is wrapped around the fixed pulley 85, and its other end is fixed to one side of the baffle 7. When the baffle 7 moves down, the baffle 7 will pull the traction rope 851. At this time, the traction rope 851 will pull the slide plate 81 to move in the slide groove 52, so that the anti-clogging head 831 moves to the bottom of the corresponding screen hole 51.

[0040] Furthermore, a mounting plate 86 is fixed to the right side of the slide plate 81, and a telescopic component 861 is installed on the mounting plate 86. The telescopic component 861 can be an electric telescopic rod. A rocker 87 passes through the slide plate 81. The rocker 87 is located inside the slide plate 81 and is rotatably connected to the inner side wall of the slide plate 81, so that the rocker 87 can rotate. The top left side of the rocker 87 abuts against the movable rod 83, and the output end of the telescopic component 861 abuts against the top right side of the rocker 87. By activating the telescopic component 861 to extend, the rocker 87 rotates, so that the other end of the rocker 87 will lift the movable rod 83, allowing the anti-clogging head 831 to enter the screen hole 51 and push out the ore blocking the screen hole 51, thereby effectively preventing the screen hole 51 from clogging.

[0041] Furthermore, a fixing plate 88 is fixed to the right side of the slide plate 81 at the bottom of the screening plate 5. An elastic element 89 is evenly connected between the fixing plate 88 and the slide plate 81. The elastic element 89 can be a spring. When the baffle 7 moves up, the traction rope 851 loosens. At this time, due to the rebound ability of the elastic element 89, the slide plate 81 returns to the initial position.

[0042] During screening, when the baffle 7 moves downward, it pulls the traction rope 851. The traction rope 851 then pulls the slide plate 81 to move within the chute 52, causing the anti-clogging head 831 to move below the corresponding screen hole 51. At this point, the telescopic component 861 extends, causing the rocker arm 87 to rotate. This causes the other end of the rocker arm 87 to lift the movable rod 83, allowing the anti-clogging head 831 to enter the screen hole 51 and push out the ore blocking the screen hole 51, thus effectively preventing clogging. When 61 retracts, due to the rebound ability of elastic element 84, the anti-blocking head 831 moves downward, and the rocker 87 slowly returns to its initial position. This reciprocating control of telescopic element 861 to extend or retract causes the anti-blocking head 831 to move up and down, thus improving the ability of the anti-blocking head 831 to push the ore out. When the baffle 7 moves upward, the telescopic element 861 retracts and returns to its initial position. In this way, through the rebound ability of elastic element 89, the slide plate 81 returns to its initial position.

[0043] like Figure 1 and Figure 3 As shown;

[0044] A conical base 15 is provided at the bottom of the inner cavity of the feed hopper 1. The conical base 15 allows the ore entering the feed hopper 1 to slide down and fall onto the guide plate 2 through the discharge port 12. A rotating shaft 13 is installed through the bottom of the conical base 15. A drive component 17, which can be a motor, is connected to the lower end of the rotating shaft 13. A support frame 18 is provided at the bottom of the feed hopper 1, and the drive component 17 is installed on the support frame 18. Push plates 14 are symmetrically arranged around the rotating shaft 13. The bottom of the push plates 14 is in contact with the surface of the conical base 15. By starting the drive component 17, the rotating shaft 13 is rotated, which causes the push plates 14 to rotate around the rotating shaft 13 and push the ore to rotate on the conical base 15. This can prevent all the ore from sliding down and blocking the discharge port 12. On the other hand, it can ensure that the amount of ore passing through the discharge port 12 is uniform each time, which can avoid the accumulation of ore and reduce the screening effect. It can also reduce the speed of the ore sliding down, so that the larger ore can drive the smaller ore to continue to slide down.

[0045] Furthermore, cleaning rollers 9 are symmetrically installed below the feed inlet 11 inside the feed barrel 1. Both ends of the cleaning rollers 9 are rotatably connected to the inner wall of the feed barrel 1, and one end of the cleaning rollers 9 passes through the feed barrel 1 and is connected to an external drive device. The external drive device causes the two cleaning rollers 9 to rotate, cleaning the surface of the ore entering the feed barrel 1 from the feed inlet 11, removing the dirt attached to the surface, thereby ensuring that the ore is in its true size state, so that the screening results are more accurate during screening, and at the same time, it can keep the surface of the ore clean, which is convenient for its subsequent use.

[0046] Furthermore, the conical base 15 has evenly spaced drainage holes 16 at its inclined bottom, through which the cleaned-up soil is discharged.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
