Description

Technical Field

[0001] This invention relates to the field of ore screening technology, and in particular to an intelligent triaxial elliptical vibrating screen. Background Technology

[0002] Vibrating screens are among the most critical pieces of machinery in the ore mining and processing industry, an indispensable component of the entire production line. They utilize vibration on a porous working surface (screen) to separate particles of different sizes, thus achieving ore screening. Equipment specifically designed for screening quarries can also be used for product grading in coal preparation, mineral processing, building materials, power, and chemical industries. With the rapid development of modern industry, the requirements for material screening are increasingly stringent. Traditional single-shaft and dual-shaft vibrating screens are gradually showing their limitations when handling complex materials and high-volume demands. For example, in the mining industry, with the increase in ore extraction and the diversification of ore types, there is a need for equipment that can more efficiently separate ores of different particle sizes, handle large volumes, and achieve high screening accuracy. The construction industry also has increasingly stringent requirements for the quality and particle size distribution of building materials such as sand and gravel to meet the demands of high-quality construction projects.

[0003] A search revealed Chinese invention patent CN118768207A, which discloses an intelligent triaxial elliptical vibrating screen. The invention comprises a base and a vibrating screen body, with the vibrating screen body located above the base. Two U-shaped frames are fixedly installed on both sides of the vibrating screen body. Multiple connecting components are located on the top of the base, with the tops of the connecting components fixedly connected to the U-shaped frames. Multiple elastic components are also located on the top of the base, positioned in the middle of the connecting components. T-shaped rods are fixedly installed at the bottom of each U-shaped frame. Shock-absorbing components are installed inside the strip grooves on both sides of the base, located on the inner bottom wall of the base. Through a first detection unit, a second detection unit, a status detection system, and a controller, the system can monitor the operating status of the vibrating screen body in real time, analyze and warn of abnormal states, and provide fault diagnosis. Furthermore, it can determine the load based on the operating status and adjust the output of the transmission system to adjust the operating status and reduce the energy consumption per unit of finished product.

[0004] However, in actual use, when the above-mentioned device is used to screen and sort ore using a triaxial vibrating screen, if there are larger ore pieces outside the screen, smaller ore pieces on top of the larger ore pieces will form a pile. The smaller ore pieces on top will have difficulty passing through the screen quickly, resulting in a significant reduction in screening efficiency and low work efficiency. Therefore, an intelligent triaxial elliptical vibrating screen is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, when using a triaxial vibrating screen to screen and sort ores, if there are larger ores outside the screen, smaller ores will pile up on top of the larger ores, making it difficult for the smaller ores on top to pass through the screen quickly, resulting in a significant reduction in screening efficiency and low work efficiency. Therefore, this invention proposes an intelligent triaxial elliptical vibrating screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent triaxial elliptical vibrating screen includes a first screening box, with a fixed plate fixedly connected above the first screening box. A reciprocating vibration mechanism is provided outside the fixed plate. The reciprocating vibration mechanism includes a first motor located outside the fixed plate. A transmission rod is provided at the output end of the first motor. A coupling is fixedly connected to the side of the transmission rod away from the first motor. A round shaft block is rotatably connected to the side of the coupling. A pull rod is rotatably connected to the side of the round shaft block near the coupling. A connecting rod is rotatably connected to the side of the pull rod away from the round shaft block. A screen plate is fixedly connected to the side of the connecting rod away from the pull rod. The screen plate is inclined and located above the first screening box. After the first motor is started, it drives the coupling to rotate circumferentially through the transmission rod. The coupling drives the pull rod to move in a pulling motion through the round shaft block. The pull rod drives the screen plate to move reciprocally. The operation of the first motor causes the screen plate to change from a stationary state to a reciprocating motion state with vibration.

[0008] The above technical solution further includes:

[0009] The fixed plate is fixedly connected to the first motor, and an mounting plate is fixedly connected to the side of the first screening box. An elastic vibrator is installed above the mounting plate, and a connecting plate is fixedly connected to the side of the elastic vibrator away from the mounting plate. The connecting plate is fixedly connected to the screen plate.

[0010] A base plate is fixedly connected to the side of the screen plate.

[0011] A triaxial vibration mechanism is provided on the outside of the substrate. The triaxial vibration mechanism includes a second motor provided on the outside of the substrate. A main drive shaft is provided at the output end of the second motor. A first gear is fixedly connected to the side of the main drive shaft near the second motor. A second gear is meshed with the side of the first gear. A first drive shaft is fixedly connected to the side of the second gear. The operation of the second motor causes the main drive shaft and the first drive shaft to change from a stationary state to a rotating state.

[0012] The first gear is connected to a second drive shaft on the side away from the second gear, and the second drive shaft is driven to rotate by the same set of second gears.

[0013] A horizontal plate is fixedly connected to the side of the substrate near the screen plate. The horizontal plate is fixedly connected to the screen plate, rotatably connected to the main drive shaft, and rotatably connected to the first drive shaft.

[0014] A gear transmission is slidably connected above the horizontal plate, and both the main drive shaft and the first drive shaft pass through the interior of the gear transmission.

[0015] The vibrator assembly is located on the side of the horizontal plate away from the substrate.

[0016] A spring is fixedly connected to the upper inner side of the first screening box, and the spring is fixedly connected to the screen plate.

[0017] A sliding plate is fixedly connected below the screen plate, and a second screening box is provided on the side of the first screening box near the sliding plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. In this invention, through the reciprocating vibration mechanism, the first motor drives the transmission rod and the connecting rod to drive the connecting shaft to rotate in a circular motion. The connecting shaft drives the pull rod to move in a pulling motion, causing the screen plate to move back and forth with vibration. This motion mode can effectively prevent smaller ores from piling up on top of larger ores, allowing smaller ores to pass through the screen plate more quickly, thereby significantly improving screening efficiency.

[0020] 2. In this invention, the triaxial vibration mechanism is driven by a second motor. Through the transmission of the main drive shaft, the first gear, the second gear, the first drive shaft, and the second drive shaft, the three-axis rotation is realized. Combined with the vibrator assembly and the spring, it generates a strong vibration effect on the screen plate. This triaxial elliptical vibration not only enhances the screening force but also improves the screening accuracy, enabling the ore to be classified more accurately according to size.

[0021] 3. In this invention, by cleverly combining the reciprocating vibration mechanism and the triaxial vibration mechanism, efficient screening of ore is achieved. At the same time, the frequency and amplitude of vibration can be flexibly adjusted by the gear transmission to adapt to the screening requirements of different ores. In addition, the design of the slide plate and the second screening box makes it easy to collect and store the screened ore. Attached Figure Description

[0029] 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.

[0030] Example 1

[0031] like Figures 1-6 As shown, the present invention proposes an intelligent triaxial elliptical vibrating screen, comprising a first screening box 1, a fixed plate 2 fixedly connected above the first screening box 1, a reciprocating vibration mechanism provided outside the fixed plate 2, the reciprocating vibration mechanism including a first motor 3 provided outside the fixed plate 2, a transmission rod 4 provided at the output end of the first motor 3, a connecting shaft 5 fixedly connected to the side of the transmission rod 4 away from the first motor 3, a round shaft block 6 rotatably connected to the side of the connecting shaft 5, a pull rod 7 rotatably connected to the side of the round shaft block 6 near the connecting shaft 5, a connecting rod 8 rotatably connected to the side of the pull rod 7 away from the round shaft block 6, and a screen plate 9 fixedly connected to the side of the connecting rod 8 away from the pull rod 7. The screen plate 9 is inclined and set above the first screening box 1. After the first motor 3 is started, it drives the connecting shaft 5 to rotate circumferentially through the transmission rod 4. The connecting shaft 5 drives the pull rod 7 to move in a pulling manner through the round shaft block 6. The pull rod 7 drives the screen plate 9 to move reciprocally. The operation of the first motor 3 causes the screen plate 9 to change from a static state to a reciprocating and vibrating motion state.

[0032] The fixed plate 2 is fixedly connected to the first motor 3. The first screening box 1 is fixedly connected to the side of the mounting plate 1. An elastic vibrator 11 is installed above the mounting plate 10. A connecting plate 12 is fixedly connected to the side of the elastic vibrator 11 away from the mounting plate 10. The connecting plate 12 is fixedly connected to the screen plate 9.

[0033] In this embodiment, a fixed plate 2 is fixedly connected above the first screening box 1. When the reciprocating vibration mechanism located outside the fixed plate 2 is activated, the first motor 3, fixedly installed outside the fixed plate 2, begins to run. When the first motor 3 runs, it controls the transmission rod 4 located at its output end to rotate. When the transmission rod 4 rotates, it drives the coupling 5, which is fixedly connected to its other end, to rotate. A round shaft block 6 is fixedly connected to the side of the coupling 5. When the coupling 5 rotates, it drives the round shaft block 6 to begin circumferential movement. When the round shaft block 6 moves, it drives the pull rod 7, which is rotatably connected to its side, to begin moving. A connecting rod 8 is rotatably connected to the side of the pull rod 7 away from the round shaft block 6. The pull rod 7 rotates outside the connecting rod 8. Restricted by the connecting rod 8, the pull rod 7 forms a pull-out movement, which drives the connecting rod 8 to perform a pull-out movement. A screen plate 9 is fixedly connected to the other end. The connecting rod 8 drives the screen plate 9 to reciprocate and pull. An installation plate 10 is fixedly connected to the side of the first screening box 1. An elastic vibrator 11 is set above the installation plate 10. The elastic vibrator 11 is elastic. The other side of the elastic vibrator 11 is connected to the screen plate 9 through the connecting plate 12. When the screen plate 9 moves in a pulling motion, it drives the elastic vibrator 11 to twist. The elastic vibrator 11 causes the screen plate 9 to vibrate slightly when it moves due to its own elasticity. The screen plate 9 is connected to the first screening box 1 through the connection of multiple sets of installation plates 10, elastic vibrators 11, and connecting plates 12. The screen plate 9 is tilted and presented above the first screening box 1. When the screen plate 9 moves and vibrates in a reciprocating manner, the smaller ore at the top is shaken to a flat state and will not form a pile, resulting in a significant improvement in screening efficiency.

[0034] Example 2

[0035] like Figures 1-6 As shown, based on Embodiment 1, a base plate 13 is fixedly connected to the side of the screen plate 9.

[0036] A triaxial vibration mechanism is provided on the outside of the substrate 13. The triaxial vibration mechanism includes a second motor 14 provided on the outside of the substrate 13. A main drive shaft 15 is provided at the output end of the second motor 14. A first gear 16 is fixedly connected to the side of the main drive shaft 15 near the second motor 14. A second gear 17 is meshed with the side of the first gear 16. A first drive shaft 18 is fixedly connected to the side of the second gear 17. The operation of the second motor 14 causes the main drive shaft 15 and the first drive shaft 18 to change from a stationary state to a rotating state.

[0037] The first gear 16 is connected to a second drive shaft 19 on the side away from the second gear 17. The second drive shaft 19 is driven to rotate by the same set of second gears 17.

[0038] A horizontal plate 20 is fixedly connected to the side of the substrate 13 near the screen plate 9. The horizontal plate 20 is fixedly connected to the screen plate 9, and the horizontal plate 20 is rotatably connected to the main drive shaft 15 and the first drive shaft 18.

[0039] A gear transmission 21 is slidably connected above the horizontal plate 20, and both the main drive shaft 15 and the first drive shaft 18 pass through the inside of the gear transmission 21.

[0040] A vibrator assembly 22 is provided on the side of the horizontal plate 20 away from the substrate 13.

[0041] A spring 23 is fixedly connected to the upper inner side of the first screening box 1, and the spring 23 is fixedly connected to the screen plate 9.

[0042] A slide plate 24 is fixedly connected below the screen plate 9, and a second screening box 25 is provided on the side of the first screening box 1 near the slide plate 24.

[0043] In this embodiment, a base plate 13 is fixedly connected to the side of the screen plate 9. When the triaxial vibration mechanism outside the base plate 13 is activated, the second motor 14 fixedly installed outside the base plate 13 starts to run. When the second motor 14 runs, it starts to control the main drive shaft 15 located at its output end to rotate. The main drive shaft 15 rotates inside the horizontal plate 20. When the main drive shaft 15 rotates, it drives the first gear 16 fixedly connected to its side to rotate. When the first gear 16 rotates, it drives the second gear 17 meshed with its side to start rotating. When the second gear 17 rotates, it drives the first drive shaft 18 fixedly connected to its outside to rotate inside the horizontal plate 20. On the other side of the main drive shaft 15, the same set of second gears 17 meshes and drives another set of second drive shafts 19 to start rotating in the same way. The main drive shaft 15, the first gear 16, the second gear 17, the second gear 18, the second gear 19, the third gear 18, the fourth gear 19, the fifth gear 18, the sixth gear 19, the seventh gear 18, the eighth gear 19, the ninth gear 18, the eleventh ... Both drive shaft 18 and second drive shaft 19 rotate inside the horizontal plate 20, achieving three-axis rotation. The main drive shaft 15, first drive shaft 18, and second drive shaft 19 are all connected to the gear transmission 21, which can adjust the rotation speed of the main drive shaft 15, first drive shaft 18, and second drive shaft 19. On the other side of the horizontal plate 20, there is a vibrator assembly 22. By connecting with the three shafts, the vibrator assembly 22 starts to vibrate. The vibrator assembly 22 vibrates the screen plate 9 through multiple sets of springs 23 connected to the screen plate 9 and the first screening box 1, achieving the three-axis vibration function. This enables the vibration screening function of the ore above the screen plate 9. In cooperation with the reciprocating shaking mechanism, smaller ore falls into the first screening box 1, while larger ore moves to the slide plate 24 and falls into the second screening box 25 for storage.
