Description

Technical Field

[0001] This utility model relates to the field of ore screening technology, specifically to an ore screening machine for mining. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. It can be divided into metallic minerals and non-metallic minerals. The raw ore mined from mines is often of varying sizes and has a complex composition, and needs to be effectively screened before it can be further processed. Ore screening machine is an auxiliary device used for screening coarse and fine ores.

[0003] Traditional ore screening machines often fail to ensure even distribution of ore on the screen during the feeding process. This can lead to excessive ore accumulation in some screening areas and insufficient ore in others, significantly impacting screening efficiency and effectiveness. Furthermore, traditional ore screening machines cause direct impact on the screen plate after the ore enters from the feed inlet. This not only causes significant wear and shortens the screen plate's lifespan but also allows ore to accumulate in localized areas of the screen plate without buffering or guidance, affecting the uniformity and smoothness of the screening process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mining ore screening machine that solves the problem of uneven ore distribution during screening in traditional ore screening machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mining ore screening machine, comprising a housing, an annular sliding groove plate fixedly connected to the top of the inner cavity of the housing, sliders slidably mounted on both sides inside the annular sliding groove plate, a stabilizing plate fixedly connected to the bottom of the sliders, a material distribution frame fixedly connected between two stabilizing plates via a connecting rod, a plurality of material distribution ports annularly opened at the bottom of the material distribution frame, a horizontal plate fixedly connected to the top of one side of the housing, a drive motor fixedly connected to the bottom of the horizontal plate, and a rotating rod fixedly connected to the output end of the drive motor via a coupling. The outer periphery of the rotating rod is fixedly fitted with a first pulley. One side of the inner cavity of the box is rotatably connected to a second pulley via a rotating component. The first pulley and the second pulley are connected by a belt drive. One side of the box has a groove for use with the belt. The bottom of the second pulley is fixedly connected to a rotating gear. The outer periphery of the material distribution frame is fixedly fitted with an annular toothed plate that meshes with the rotating gear. Both sides of the box are fixedly connected to sliding rods. The outer periphery of the sliding rods is fitted with and slidably connected to sliding cylinders. The tops of the two sliding cylinders are fixedly connected to a screen plate via a connecting block.

[0006] Preferably, an eccentric wheel is fixedly connected to the bottom end of the rotating rod, an annular contact plate is fixedly connected to the bottom of the eccentric wheel, and a U-shaped frame that cooperates with the annular contact plate is fixedly connected to one side of the sieve plate through a connecting block.

[0007] Preferably, one side of the box body is provided with a through groove for use with the sieve plate, and the other side of the box body is provided with a discharge port for use with the sieve plate.

[0008] Preferably, guide rods are fixedly connected to the front and rear of one side of the sieve plate, and L-shaped rods are fixedly connected to the top of the guide rods. Movable plates are fixedly connected to the ends of the two L-shaped rods and to the front and rear of the box. Several round rods are fixedly connected at equal intervals between the two moving plates. Several transverse grooves that cooperate with the round rods are opened on the front and rear sides of the box. Baffles are fixedly connected to the surface of the round rods and to the inner cavity of the box.

[0009] Preferably, the top of the box is provided with a feeding hopper through an opening.

[0010] Preferably, the front side of the box is hinged with a door through an opening.

[0011] This utility model provides an ore screening machine for mining. It has the following beneficial effects:

[0012] (1) This utility model, through the cooperation of the drive motor, rotating rod, first pulley, second pulley, rotating gear, annular toothed plate, eccentric wheel, annular contact plate and U-shaped frame, enables the ore to be evenly fed through the distribution port after entering the distribution frame from the feed hopper. This avoids the local accumulation or uneven distribution of ore on the screen plate. At the same time, the eccentric wheel drives the U-shaped frame and screen plate to move back and forth through the annular contact plate. The reciprocating motion of the screen plate can make the ore roll and jump continuously on the screen plate, which improves the overall screening efficiency to a certain extent. This allows smaller ore particles to fall through the screen plate, while larger ore particles are discharged through the discharge port.

[0013] (2) This utility model, through the cooperation between the guide rod, L-rod, moving plate, round rod and baffle structure, enables the baffle to move synchronously while the screen plate moves back and forth. The baffle can play a certain role in buffering and guiding the falling ore. During the falling process, the ore first hits the baffle, which reduces the impact force and avoids direct impact on the screen plate, thereby extending the service life of the screen plate. At the same time, the reciprocating movement of the baffle also guides the falling ore to the surroundings, allowing the ore to be more evenly distributed on the screen plate, ensuring that the screen plate can fully play its screening role and improve screening efficiency.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-8 This utility model provides a technical solution: a mining ore screening machine, including a box body 1, a feeding hopper 27 with an opening on the top of the box body 1, a door 28 hinged to the front of the box body 1 with an opening, an annular sliding plate 2 fixedly connected to the top of the inner cavity of the box body 1, sliders 3 slidably installed on both sides inside the annular sliding plate 2, a stabilizing plate 4 fixedly connected to the bottom of the sliders 3, and a material distribution frame 5 fixedly connected between the two stabilizing plates 4 by a connecting rod, and a plurality of material distribution ports 6 annularly opened at the bottom of the material distribution frame 5;

[0025] To avoid concentrated ore feeding and poor screening effect, a horizontal plate 7 is fixedly connected to the top of one side of the box 1. A drive motor 8 is fixedly connected to the bottom of the horizontal plate 7. The drive motor 8 is powered by an external power source. The output end of the drive motor 8 is fixedly connected to a rotating rod 9 through a coupling. A first pulley 10 is fixedly sleeved on the outer periphery of the rotating rod 9. A second pulley 11 is rotatably connected to one side of the inner cavity of the box 1 through a rotating component. The first pulley 10 and the second pulley 11 are connected by belt drive. A slot for use with the belt is opened on one side of the box 1. A rotating gear 12 is fixedly connected to the bottom of the second pulley 11. An annular toothed plate 13 that meshes with the rotating gear 12 is fixedly sleeved on the outer periphery of the material distribution frame 5. Slide rods 14 are fixedly connected to both sides of the box 1. Slide cylinders 15 are sleeved and slidably connected to the outer periphery of the slide rods 14. The tops of the two slide cylinders 15 are fixedly connected to a screen plate 16 through a connecting block.

[0026] Furthermore, in order to improve the screening efficiency of ore, an eccentric wheel 17 is fixedly connected to the bottom of the rotating rod 9, and an annular contact plate 18 is fixedly connected to the bottom of the eccentric wheel 17. A U-shaped frame 19 that works in conjunction with the annular contact plate 18 is fixedly connected to one side of the screen plate 16 through a connecting block.

[0027] To facilitate the collection of larger ore particles, the screen plate 16 is inclined, and a through groove is provided on one side of the box body 1 to cooperate with the screen plate 16. The discharge port 20 is provided on the other side of the box body 1 to cooperate with the screen plate 16.

[0028] Furthermore, to prevent the falling ore from directly impacting the screen plate 16, guide rods 21 are fixedly connected to the front and rear of one side of the screen plate 16. L-rods 22 are fixedly connected to the top of the guide rods 21. Movable plates 23 are fixedly connected to the ends of the two L-rods 22 and to the front and rear of the box body 1. Several round rods 24 are fixedly connected at equal intervals between the two moving plates 23. Several transverse grooves 25 that cooperate with the round rods 24 are opened on the front and rear sides of the box body 1. Baffles 26 are fixedly connected to the surface of the round rods 24 and to the inner cavity of the box body 1.

[0029] During operation, the ore to be screened is continuously fed into the housing 1 from the feed hopper 27. The drive motor 8 is started, which drives the rotating rod 9 to rotate. The rotating rod 9 drives the second pulley 11 to rotate via the first pulley 10. The rotating gear 12 rotates synchronously with the second pulley 11. The rotating gear 12 drives the distribution frame 5 to rotate via the annular toothed plate 13. As the distribution frame 5 rotates, the ore is evenly fed through several distribution ports 6 within the distribution frame 5 under the action of rotation. At the same time, the rotating rod 9 drives the eccentric wheel 17 to rotate. During the rotation of the eccentric wheel 17, it passes through the annular contact plate. 18 pushes the U-shaped frame 19, thereby driving the screen plate 16 to reciprocate. While the screen plate 16 is reciprocating, the screen plate 16 drives the round rod 24 and the baffle 26 to reciprocate through the guide rod 21, the L rod 22 and the moving plate 23. During the reciprocating movement, the baffle 26 plays a buffering and guiding role on the falling ore, so that the ore is evenly distributed on the screen plate 16. The reciprocating movement of the screen plate 16 accelerates the screening of the ore. After the ore is screened by the screen plate 16, the smaller particles fall into the box 1, and the larger particles are discharged through the discharge port 20.
