Technical Field
[0001] This invention relates to the field of triaxial elliptical horizontal screen technology, specifically a triaxial composite horizontal screen device. Background Technology
[0002] The triaxial composite horizontal screen is a screening device whose core structure consists of three cooperating screen shafts. Through a unique shaft system design and motion mode, the screen surface generates a complex three-dimensional motion trajectory. This device is mainly used for fine screening and grading of various granular and powdery materials. It is widely used in mining, chemical, food, building materials and other industries, and can efficiently separate materials of different particle sizes and properties according to set requirements, realizing the screening, purification and grading of materials to meet the requirements of particle size distribution and quality in production and processing.
[0003] Existing screens have fixed angles, making it difficult to adapt to diverse material screening needs. For materials with different properties, the fixed angle leads to low screening efficiency, material clogging of the screen, and inability to guarantee screening accuracy, thus limiting the applicability and versatility of screening equipment under different working conditions. Summary of the Invention

[0006] By adopting the above technical solution, the rotation of the knob drives the worm gear to rotate, which in turn drives the worm wheel and the second gear to rotate. The second gear meshes with the first rack, driving the moving box and connecting frame to rotate around the hinge, thus realizing rapid adjustment of the screen angle. At the same time, the second gear drives the third gear, which pushes the grid plate to slide through the second rack, changing the screen aperture size so that the angle and aperture are synchronously adapted to the material characteristics.

[0008] Preferably, the leveling component includes a feeding hopper, which is fixedly connected to the outer shell. A reciprocating screw is rotatably connected to the right side of the feeding hopper. A moving block is threadedly connected to the surface of the reciprocating screw. A support frame is fixedly connected to the top of the connecting frame. A push plate is slidably connected to the surface of the support frame. A groove is provided on the surface of the push plate. The moving block slides inside the push plate through the groove.
[0009] Preferably, the vibration assembly includes multiple connecting shafts, each of which is rotatably connected to the housing. Each of the multiple connecting shafts has a first gear fixedly connected to both ends, and each of the multiple first gears has an eccentric wheel fixedly connected to the end away from the connecting shaft. Adjacent first gears are meshed together.
[0010] Preferably, a plurality of third springs are fixedly connected to the inner wall of the outer shell, a fine sieve plate is fixedly connected between the plurality of third springs, and a high-frequency vibrator is fixedly connected to the bottom of the fine sieve plate.
[0011] Preferably, the support assembly includes a plurality of first springs, one end of each of the plurality of first springs being fixedly connected to the outer shell, and the other ends of the plurality of first springs being fixedly connected to a base.
[0012] Preferably, the drive assembly includes a motor, which is fixedly connected to the base. A first rotating wheel is fixedly disposed at the output end of the motor. Multiple mounting boxes are fixedly connected to the surface of the housing. Multiple second rotating wheels are rotatably connected to the surface of the mounting boxes. Each of the multiple second rotating wheels is fixedly connected to an adjacent eccentric wheel. A second belt is disposed between the first rotating wheel and the adjacent second rotating wheel.
[0013] Preferably, a support rod is rotatably connected to the top of the base, a support wheel is rotatably connected to the top of the support rod, the support wheel is tightly fitted with the second belt, and a second spring is fixedly connected between the support rod and the base.
[0014] Preferably, a third rotating wheel is fixedly connected to one end of the reciprocating lead screw, and a first belt is provided between the third rotating wheel and the adjacent second rotating wheel.
[0015] Preferably, a sliding rod is slidably connected inside the movable block, and both ends of the sliding rod are fixedly connected to the outer shell.
[0016] Working principle: When using the device, the user first rotates the knob according to the material characteristics to drive the worm gear to rotate. The worm gear drives the worm wheel and the second gear to rotate. Since the second gear meshes with the first rack, the rotation of the second gear drives the moving box and the connecting frame to rotate around the hinge, synchronously adjusting the angle of the connecting frame. At the same time, the second gear drives the fixedly connected third gear to rotate. The third gear drives the second rack and the grid plate to slide within the connecting frame, changing the size of the hole combination between the two, thus achieving linkage and adaptation between the angle and the hole diameter. The starter motor drives the first rotating wheel to rotate, which in turn drives the second rotating wheel to rotate via the second belt. The second rotating wheel drives the eccentric wheel and the connecting shaft to rotate. The meshing of adjacent first gears causes the eccentric wheel to rotate in two forward directions and one in reverse, generating elliptical vibration that vibrates the outer shell, connecting frame, and grid plate. The material falls from the discharge hopper. At the same time, the second rotating wheel on the left side drives the third rotating wheel via the first belt, causing the reciprocating screw to rotate. The moving block drives the push plate to reciprocate on the support frame via the slide groove, spreading the material evenly on the connecting frame. The material is screened by vibration and jumping. Fine particles fall into the fine screen plate below. The high-frequency vibrator drives the fine screen plate to vibrate independently via the third spring, realizing the tiered screening of fine materials.
[0017] This invention provides a triaxial composite horizontal screen device. It has the following beneficial effects: 1. In this invention, rotating the knob drives the worm gear to rotate, which in turn drives the worm wheel and the second gear to rotate. When the second gear rotates, it drives the connecting frame to rotate through the hinge, thereby enabling rapid adjustment of the angle of the connecting frame and the internal grid plate. This allows for quick adaptation to different material characteristics and production process requirements, significantly improving screening efficiency and quality.
[0018] 2. In this invention, rotating the knob drives the worm gear to rotate, which in turn drives the worm wheel, the second gear, and the third gear to rotate. At this time, the third gear drives the second rack and the mesh plate to move. By adjusting the relative position between the mesh plate and the connecting frame, the size of the holes between the mesh plate and the connecting frame is changed. For wet and sticky materials, the aperture can be reduced while the screen angle is increased, allowing the material to slide down faster while preventing clogging of the screen holes. For materials with large particle size differences, enlarging the aperture and adjusting the appropriate angle can improve the material throughput and screening efficiency.
[0019] 3. In this invention, when the motor drives multiple eccentric wheels to rotate via the first rotating wheel, the second belt, and the second rotating wheel, it causes the outer casing and its connected structure to vibrate in an elliptical shape. At the same time, the second rotating wheel, the first belt, and the third rotating wheel drive the reciprocating screw to rotate, causing the moving block and push plate to move back and forth. This pushes the material from the discharge hopper to a flat surface, preventing material from accumulating locally on the screen surface. This ensures that the material can be screened comprehensively and evenly, reducing blind spots and blockages caused by material accumulation, and significantly improving the processing capacity and screening quality of the screening equipment.
[0020] 4. In this invention, the fine screen plate is driven to vibrate by a high-frequency vibrator, which realizes the tiered screening of fine materials by high-frequency low-amplitude vibration. Furthermore, the fine screen plate is connected to the outer shell by a third spring, so that the vibration of the fine screen plate is independent of the outer shell, avoiding interference. This solves the problems of large footprint, high energy consumption, and complex maintenance when using multiple devices in series to screen coarse and fine materials in the prior art. The integrated design can simultaneously complete the efficient screening of coarse and fine materials, improve accuracy and efficiency, and simplify the structure. Attached Figure Description

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.
[0024] Please see the appendix Figure 1 -Appendix Figure 6 This invention provides a triaxial composite horizontal screen device, including a housing 1. Multiple hinges 34 are fixedly connected to the left side of the inner wall of the housing 1. A connecting frame 21 is fixedly connected between the multiple hinges 34. A movable box 16 is fixedly connected to the front side of the connecting frame 21. A knob 17 is rotatably connected to the surface of the movable box 16. A worm gear 23 is fixedly connected to one end of the knob 17 near the movable box 16. A worm wheel 24 is meshed with the surface of the worm gear 23. One end of the worm wheel 24 is rotatably connected to the movable box 16. A second gear 25 is fixedly connected to the other end of the worm wheel 24. A first rack 18 is meshed with the surface of the second gear 25. The first rack 18 is fixedly connected to the housing 1. A support assembly is provided at the bottom of the housing 1. A drive assembly is fixedly connected to the top of the support assembly. An adjustment assembly is provided at the end of the second gear 25 away from the worm wheel 24. A leveling assembly is provided at the top of the housing 1. A vibration assembly is provided inside the housing 1.
[0025] Specifically, when the user operates the device, turning the knob 17 drives the worm gear 23 to rotate, which in turn drives the worm wheel 24 and the second gear 25 to rotate. Since the first rack 18 is fixed to the outer casing 1, the second gear 25, during its rotation, meshes with the first rack 18, causing the moving box 16 to move. The moving box 16 then drives the connecting frame 21 to rotate via the hinge 34, thereby adjusting the angle of the connecting frame 21 and its internal grid plate 22. At this time, the appropriate angle can be quickly adjusted according to the material characteristics and production process requirements. The first rack 18 is arc-shaped, with its center being the rotation axis of the hinge 34, thus ensuring that the second gear 25 always meshes with the first rack 18 when the connecting frame 21 rotates via the hinge 34.
[0026] See appendix Figure 6 and attached Figure 7 The adjustment component includes a third gear 26, which is fixedly connected to a second gear 25. A grid plate 22 is slidably connected to the inner wall of the connecting frame 21. A second rack 27 is fixedly connected to the side of the grid plate 22 near the third gear 26. The second rack 27 is meshed with the third gear 26.
[0027] Specifically, when the knob 17 is turned, the worm gear 23 rotates, which in turn drives the worm wheel 24, the second gear 25, and the third gear 26 to rotate. The third gear 26 meshes with the second rack 27. When the third gear 26 rotates, it pushes the second rack 27 and the grid plate 22 to slide within the connecting frame 21, thereby adjusting the relative position between the grid plate 22 and the connecting frame 21. Since both the connecting frame 21 and the grid plate 22 have holes on their surfaces, the aperture of the combined mesh plate 22 is changed. Adjusting the aperture also causes the connecting frame 21 to adjust its angle. This allows for a reduction in the screen aperture and an increase in the tilt angle when processing wet and sticky materials. This reduces the probability of material getting stuck in the screen holes and accelerates the material's sliding speed, preventing blockage and improving processing efficiency. For materials with large particle size differences, enlarging the aperture and adjusting it to a suitable angle can ensure the material throughput while allowing large particles to move faster towards the bottom of the screen and fine particles to pass through more fully, avoiding the mixing of coarse and fine materials that affects the screening accuracy.
[0028] See appendix Figure 8 The leveling component includes a feeding hopper 12, which is fixedly connected to the outer shell 1. A reciprocating screw 28 is rotatably connected to the right side of the feeding hopper 12. A moving block 30 is threadedly connected to the surface of the reciprocating screw 28. A support frame 33 is fixedly connected to the top of the connecting frame 21. A push plate 31 is slidably connected to the surface of the support frame 33. A groove 32 is opened on the surface of the push plate 31. The moving block 30 slides inside the push plate 31 through the groove 32.
[0029] Specifically, when the reciprocating screw 28 rotates, the moving block 30 reciprocates linearly along the reciprocating screw 28. The moving block 30 is slidably connected to the push plate 31 through the slide groove 32, and the push plate 31 is slidably connected to the support frame 33. When the moving block 30 moves, it drives the push plate 31 to reciprocate linearly on the surface of the support frame 33 through the slide groove 32. The hopper 12 feeds the material onto the connecting frame 21 and the grid plate 22. The reciprocating motion of the push plate 31 evenly spreads the material, preventing material accumulation. The slide groove 32 is arc-shaped, with the hinge at its center. The 34 rotating shaft allows the support frame 33 and push plate 31 to move synchronously when the angle of the connecting frame 21 is adjusted. No matter how the tilt angle of the connecting frame 21 changes, the push plate 31 can always be in contact with the material surface at the top of the connecting frame 21 for uniform spreading. This avoids the spreading effect being affected by the change in the distance between the push plate 31 and the screen surface due to the angle adjustment, ensuring that the material is evenly distributed on the screen surface, so that the material can be fully and completely screened, improving screening efficiency and quality, and reducing screening blind spots and blockages caused by material accumulation.
[0030] See appendix Figure 3 and attached Figure 5The vibration assembly includes multiple connecting shafts 36, all of which are rotatably connected to the outer casing 1. Each end of the multiple connecting shafts 36 is fixedly connected to a first gear 14, and each end of the multiple first gears 14 away from the connecting shafts 36 is fixedly connected to an eccentric wheel 15. Adjacent first gears 14 are meshed together.
[0031] Specifically, motor 4 drives the connecting shaft 36 and the first gear 14 on the right side to rotate via the first rotating wheel 5, the second belt 37, and the second rotating wheel 6. Since the adjacent first gears 14 mesh with each other, the rotation of the first gear 14 will drive the adjacent first gear 14 to rotate in the opposite direction, thereby realizing the forward rotation of two shafts and the reverse rotation of one shaft. The centrifugal force generated by the eccentric wheel 15 during rotation is superimposed to form an elliptical vibration trajectory, which drives the outer shell 1, connecting frame 21, grid plate 22 and other structures to produce elliptical vibration, so that the material jumps and rolls fully on the screen surface. Through the synchronous reverse rotation of multiple sets of eccentric wheels 15, the equipment produces stable and efficient elliptical vibration, which promotes the uniform distribution of material on the screen surface and full contact with the screen mesh, improves screening efficiency and accuracy, and reduces the phenomenon of material clogging the screen holes.
[0032] See appendix Figure 5 Multiple third springs 19 are fixedly connected to the inner wall of the outer shell 1. A fine sieve plate 20 is fixedly connected between the multiple third springs 19. A high-frequency vibrator 35 is fixedly connected to the bottom of the fine sieve plate 20.
[0033] Specifically, when the user turns on the high-frequency vibrator 35, the high-frequency vibrator 35 generates high-frequency vibrations that are transmitted to the fine sieve plate 20. The fine sieve plate 20 is elastically connected to the outer casing 1 through the third spring 19 connected to the bottom, which reduces the vibration transmitted to the outer casing 1.
[0034] See appendix Figure 1 and attached Figure 3 The support assembly includes multiple first springs 3, one end of each of the multiple first springs 3 is fixedly connected to the outer shell 1, and the other end of the multiple first springs 3 is fixedly connected to a base 2.
[0035] Specifically, when the equipment is running, the vibration generated will be transmitted to the outer casing 1. When the outer casing 1 tends to displace due to vibration, the first spring 3 will buffer the vibration energy by compression or stretching, limiting the vibration of the outer casing 1 to a certain range, and preventing the vibration from being directly transmitted to the base 2 and the ground, causing the entire equipment to shake or generate noise.
[0036] See appendix Figure 1 and attached Figure 2The drive assembly includes a motor 4, which is fixedly connected to the base 2. A first rotating wheel 5 is fixedly installed at the output end of the motor 4. Multiple mounting boxes 13 are fixedly connected to the surface of the housing 1. Multiple second rotating wheels 6 are rotatably connected to the surface of the mounting boxes 13. The multiple second rotating wheels 6 are fixedly connected to the adjacent eccentric wheel 15. A second belt 37 is provided between the first rotating wheel 5 and the adjacent second rotating wheel 6.
[0037] Specifically, the motor 4 drives the first rotating wheel 5 to rotate, and the first rotating wheel 5 drives the second rotating wheel 6 to rotate synchronously through the second belt 37. Since multiple second rotating wheels 6 are fixedly connected to adjacent eccentric wheels 15, they are driven to rotate through the meshing transmission between the first gear 14. The eccentric wheels 15 generate centrifugal force during rotation, which in turn causes the outer shell 1 and its connecting structure to produce elliptical vibration.
[0038] See appendix Figure 1 and attached Figure 2 A support rod 7 is rotatably connected to the top of the base 2, and a support wheel 9 is rotatably connected to the top of the support rod 7. The support wheel 9 is tightly fitted with the second belt 37, and a second spring 8 is fixedly connected between the support rod 7 and the base 2.
[0039] Specifically, when the motor 4 drives the first rotating wheel 5 to rotate and transmits power through the second belt 37, the outer casing 1 will cause the second rotating wheel 6 to vibrate. At this time, the support rod 7 will apply pressure to the second belt 37 through the support wheel 9 under the elastic force of the second spring 8. The support wheel 9 is in close contact with the second belt 37. The support wheel 9 can adaptively adjust its angle according to the transmission direction of the second belt 37, always maintaining the tension on the second belt 37, and avoiding slippage of the second belt 37 that would affect the power transmission.
[0040] See appendix Figure 3 and attached Figure 8 A third rotating wheel 11 is fixedly connected to one end of the reciprocating screw 28, and a first belt 10 is provided between the third rotating wheel 11 and the adjacent second rotating wheel 6.
[0041] Specifically, when multiple eccentric wheels 15 rotate, they will drive the second rotating wheel 6 on the left to rotate. At this time, the first belt 10 can drive the third rotating wheel 11 and the reciprocating screw 28 to rotate.
[0042] See appendix Figure 8 The movable block 30 has a sliding rod 29 inside, and both ends of the sliding rod 29 are fixedly connected to the outer shell 1.
[0043] Specifically, the moving block 30 reciprocates in a straight line along the guide direction of the slide bar 29. The slide bar 29 restricts the movement trajectory of the moving block 30 to prevent it from deviating or wobbling during the movement, thus ensuring the movement accuracy and stability of the moving block 30.
