[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the embodiments of this invention, please refer to Figures 1 to 10 A mining ore sorting device includes a base plate 1 and a conveyor belt 2 for conveying ore. The base plate 1 is inclined. The device also includes: Connecting cylinder 3 is located outside one end of conveyor belt 2; The screening mechanism 4 is rotatably connected to the outer wall of the connecting cylinder 3 and is used for screening ore; The shaking mechanism 5 is connected to the base plate 1 at one end and to the screening mechanism 4 at the other end. It is used to support the screening mechanism 4 and drive the screening mechanism 4 to shake. Dust removal mechanism 6 is used to remove dust generated during the screening process. The dust removal mechanism 6 includes: a shielding arc plate 61, rotatably connected to the screening mechanism 4, used to shield the top of the screening mechanism 4; a first connecting hose 62, one end of which passes through and connects to the shielding arc plate 61; a connecting frame 63, connected to the base plate 1, the connecting frame 63 communicating internally with the other end of the first connecting hose 62, and the connecting frame 63 containing a filter plate 69 for filtering dust; and a second connecting hose 64, one end of which communicates internally with the connecting frame 63. The filter plate 69 is equipped with a one-way valve; a fixed cylinder 65, the bottom end of which is connected to the other end of the connecting hose 64, and the fixed cylinder 65 is connected to the shaking mechanism 5; a pumping component 66, one end of which is connected to the screening mechanism 4 and the other end of which is connected to the fixed cylinder 65, for pumping dust-laden gas; a cleaning component 67, one end of which is connected to the fixed cylinder 65 and the other end of which is connected to the connecting frame 63, for cleaning the filter plate 69; and a striking component 68, one end of which is connected to the cleaning component 67 and the other end of which is connected to the shielding arc plate 61, for striking the screening mechanism 4.

[0028] The conveyor belt 2 transports the ore to the screening mechanism 4, which performs multi-stage screening of the ore. The shaking mechanism 5 supports the screening mechanism 4 and drives it to shake during the screening process, improving the screening effect. Dust is generated during the screening process. The extraction component 66 draws the dust-laden air generated during the screening process into the fixed cylinder 65 through the connecting hose 62, the connecting frame 63, and the connecting hose 64. After the dust-laden air enters the connecting frame 63, the filter plate 69 filters the dust in the air to ensure that clean air enters the fixed cylinder 65. Then, the clean air is sent into the cleaning component 67 and the knocking component 68. The cleaning component 67 moves to clean the filter plate 69, and the knocking component 68 moves to collide with the screening mechanism 4, knocking the screening mechanism 4 to prevent the ore from clogging the screen holes.

[0029] In this embodiment, the one-way valve 1 installed on the connecting hose 2 64 is designed to ensure that the clean air in the connecting frame 63 can only enter the fixed cylinder 65 through the connecting hose 2 64, while the air in the fixed cylinder 65 cannot enter the connecting frame 63 through the connecting hose 2 64.

[0030] In this embodiment, the bottom plate 1 is inclined downward along the ore conveying direction.

[0031] As one embodiment of the present invention, please refer to Figures 1 to 5 The screening mechanism 4 includes: The fixed plate 41 is rotatably connected to the outer wall of the connecting cylinder 3; The screening cylinder 42 is connected to the fixed plate 41 at one end. The screening cylinder 42 is provided with several sets of coaxially arranged. The screening cylinder 42 has multiple sets of screening holes, and the diameter of the screening holes gradually decreases from the inside to the outside. A rotating plate 43 is rotatably connected to the other end of the screening cylinder 42, and the rotating plate 43 is provided with several sets of discharge trough plates 44. Spiral plate 45 is connected to the inner wall of screening cylinder 42; Rotating component 46 is connected to fixed plate 41 and is used to drive fixed plate 41 to rotate; The shielding arc plate 61 is located outside the outermost screening cylinder 42 and is rotatably connected to the fixed plate 41 and connected to the rotating plate 43. The rotating assembly 46 includes: Motor 461, the outer wall of the machine body is connected to the vibration mechanism 5; Gear 462 is connected to the output terminal of motor 461; The gear ring 463 is connected to the fixed plate 41 and meshes with the gear 462.

[0032] The ore is conveyed to the innermost screening cylinder 42 by the conveyor belt 2. During the screening process, the motor 461 starts, driving the gear 462 to rotate, which in turn drives the gear ring 463 and the fixed plate 41 to rotate. The fixed plate 41 drives several sets of screening cylinders 42 to rotate synchronously. The ore moves continuously in the screening cylinder 42, passing through screening holes of different diameters from the inside to the outside, realizing multi-stage screening. Since the bottom plate 1 is inclined and tilted downward along the conveying direction of the ore (that is, the end of the bottom plate 1 near the conveyor belt 2 is higher than the end of the bottom plate 1 near the discharge trough plate 44), the ore moves laterally under the guidance of the spiral plate 45 and the action of gravity, so that the screened ore can be discharged through the discharge trough plate 44, and ore of different particle sizes is discharged from different discharge trough plates 44.

[0033] As one embodiment of the present invention, please refer to Figures 1 to 3 The shaking mechanism 5 includes: Fixed bending rods 51 are provided in four sets and are symmetrically arranged about the horizontal plane of the screening cylinder 42. One set of fixed bending rods 51 is connected to the motor 461, two sets of fixed bending rods 51 are connected to the connecting cylinder 3, and the other two sets of fixed bending rods 51 are connected to the rotating plate 43. The fixed cylinder 65 is connected to one set of fixed bending rods 51. The fixed rod 52 is slidably connected to the fixed folding rod 51, and its bottom end is connected to the base plate 1; Spring 53 has its bottom end connected to the top end of the fixed rod 52, and its top end connected to the fixed folding rod 51.

[0034] The ore moves inside the screening cylinder 42, generating vibrations during the movement. Spring 53 provides elastic support and absorbs part of the vibration force to protect the screening cylinder 42. At the same time, spring 53 continuously stretches and contracts, causing the screening cylinder 42 to vibrate up and down. This vibration during screening prevents the ore from clogging the screen holes. Simultaneously, the vibration of the screening cylinder 42 improves the dispersion of the material, thereby enhancing the screening effect of the ore.

[0035] As one embodiment of the present invention, please refer to Figure 1 , Figure 5 and Figure 8 The pumping component 66 includes: Eccentric rod 661 is connected to the eccentric part of gear 462; The reciprocating frame 662 is in contact with the eccentric rod 661. The top of the sliding rod 663 is connected to the reciprocating frame 662; The piston block 664 slides against the inner wall of the fixed cylinder 65 and is connected to the bottom end of the sliding rod 663.

[0036] During the screening process, the ore is constantly moving, generating a large amount of dust. The rotation of gear 462 drives the eccentric rod 661 to revolve around the center of gear 462. The eccentric rod 661 drives the reciprocating frame 662 and the sliding rod 663 to reciprocate longitudinally. The sliding rod 663 drives the piston block 664 to reciprocate longitudinally within the fixed cylinder 65. As the piston block 664 moves upward, it draws the dust-laden air generated during the screening process into the fixed cylinder 65 through connecting hose one 62, connecting frame 63, and connecting hose two 64. After the dust-laden air enters the connecting frame 63, the filter plate 69 filters the dust in the air, ensuring that the air entering the fixed cylinder 65 is clean air.

[0037] As one embodiment of the present invention, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 10 The cleaning component 67 includes: A connecting hose 671 is connected at one end to the inside of a fixed cylinder 65, and a one-way valve 2 is provided on the connecting hose 671. The fixed tube 672 is internally connected to the other end of the connecting hose 671 and is connected to the connecting frame 63; A sliding tube 673 passes through one side of the connecting frame 63 and is slidably connected to it. The sliding tube 673 is slidably connected to the fixed tube 672 and communicates with its interior. The cleaning brush 674 is connected to the sliding tube 673 and abuts against the filter plate 69; Spring 675 is connected at one end to cleaning brush 674 and at the other end to connecting frame 63.

[0038] As the piston block 664 moves downward, it forces clean air from the fixed cylinder 65 into the connecting hose 671, fixed tube 672, and sliding tube 673. Under the action of air pressure, the sliding tube 673 moves laterally along the fixed tube 672, causing the cleaning brush 674 to move laterally. The cleaning brush 674 cleans the filter plate 69. At the same time, the second spring 675 is stretched and deformed. When the piston block 664 moves upward, the air in the fixed cylinder 65 will not flow into the fixed tube 672. Under the reaction force of the second spring 675, the cleaning brush 674 and the sliding tube 673 move in the opposite direction and return to their original positions.

[0039] In this embodiment, the one-way valve 2 provided on the connecting hose 3 671 is designed to ensure that the clean air in the fixed cylinder 65 can only enter the fixed pipe 672 and the sliding pipe 673 through the connecting hose 3 671, while the air in the fixed pipe 672 cannot enter the fixed cylinder 65 through the connecting hose 3 671.

[0040] In this embodiment, the second spring 675 has a large elastic force to ensure that the cleaning brush 674 and the sliding tube 673 can return to their original positions.

[0041] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The tapping component 68 includes: Connecting hose 681, one end of which is connected to the inside of fixed tube 672; A rotating tube 682 passes through the shielding arc plate 61 and is rotatably connected to it. The rotating tube 682 is provided in several groups and is rotatably connected to the connecting hose 681. The telescopic rod 683 is connected at one end to the rotating tube 682, and the telescopic rod 683 is provided with several sets; The striking block 684 is connected to the other end of the telescopic rod 683; Spring 3 685, one end is connected to the striking block 684, and the other end is connected to the rotating tube 682; Fan blade 686 is located inside and connected to rotating tube 682.

[0042] When the piston block 664 moves upward, the air in the fixed cylinder 65 will not flow into the fixed tube 672. Under the reaction force of the spring 675, the sliding tube 673 moves back into the fixed tube 672. At this time, the clean air in the sliding tube 673 and the fixed tube 672 enters the rotating tube 682 through the connecting hose 681 and is discharged to the outside environment through the rotating tube 682. At the same time, when the air passes through the fan blade 686, it will drive the fan blade 686 to rotate. The fan blade 686 drives the rotating tube 682 to rotate, and the rotating tube 682 drives the striking block 684 to rotate. Under the action of centrifugal force, the striking block 684 moves linearly along the telescopic rod 683. During the rotation, the striking block 684 collides with the screening cylinder 42 to prevent the ore from clogging the screen holes.

[0043] In this embodiment, the second spring 675 has a large elastic force, which ensures that the clean air in the sliding tube 673 and the fixed tube 672 can enter the rotating tube 682 through the connecting hose 681, and that when the air passes through the fan blade 686, it drives the fan blade 686 to rotate.

[0044] The working principle of this invention is as follows: The ore is conveyed to the innermost screening cylinder 42 by the conveyor belt 2. During the screening process, the motor 461 starts and drives the gear 462 to rotate, which in turn drives the gear ring 463 and the fixed plate 41 to rotate. The fixed plate 41 drives several sets of screening cylinders 42 to rotate synchronously. The ore moves continuously in the screening cylinder 42 and passes through screening holes of different diameters from the inside to the outside to achieve multi-stage screening. Guided by the spiral plate 45, the ore moves laterally and is discharged through the discharge chute 44 after screening. Ore of different particle sizes is discharged from different discharge chute 44s. The ore moves in the screening cylinder 42 and vibrates during the movement. The spring 53 provides elastic support, which makes the screening cylinder 42 shake during the screening process to prevent the ore from clogging the screen holes. At the same time, the shaking of the screening cylinder 42 improves the screening effect of the ore. Dust is generated during the screening process. Gear 462 drives eccentric rod 661, which in turn drives reciprocating frame 662 and sliding rod 663 to reciprocate longitudinally. Sliding rod 663 drives piston block 664 to reciprocate longitudinally within fixed cylinder 65. As piston block 664 moves upward, it draws dust-laden air generated during screening into fixed cylinder 65 through connecting hose 1 62, connecting frame 63, and connecting hose 2 64. After entering the connecting frame 63, the dust-laden air is filtered by filter plate 69 to ensure that the air entering fixed cylinder 65 is clean. As piston block 664 moves downward, it presses the clean air in fixed cylinder 65 into fixed pipe 672 and sliding pipe 673 through connecting hose 3 671. Under air pressure, sliding pipe 673 moves laterally along fixed pipe 672, driving cleaning brush 674 to move laterally. Cleaning brush 674 cleans filter plate 69. At the same time, spring 2 675 is stretched and deformed. As the piston block 664 moves upward again, the air inside the fixed cylinder 65 will not flow into the fixed tube 672. Under the reaction force of the second spring 675, and with sufficient elasticity, the sliding tube 673 can move back into the fixed tube 672, and the cleaning brush 674 returns to its original position. At this time, the clean air in the sliding tube 673 and the fixed tube 672 enters the rotating tube 682 through the connecting hose 681 and is discharged to the outside environment through the rotating tube 682. Simultaneously, when the air passes through the fan blade 686, it will drive the fan blade 686 to rotate. The fan blade 686 drives the rotating tube 682 to rotate, and the rotating tube 682 drives the striking block 684 to rotate. Under the action of centrifugal force, the striking block 684 moves linearly along the telescopic rod 683, and the striking block 684 collides with the screening cylinder 42 during rotation to prevent the ore from clogging the screen holes.
