Description

Technical Field

[0001] This utility model belongs to the technical field of vibrating screen tilt angle control, specifically relating to a vibrating screen tilt angle control structure with dual-axis linkage. Background Technology

[0002] A vibrating screen is a mechanical device used in processes such as material grading, screening, dewatering, and desliming. It is widely used in various industries including mining, coal, chemical, food, and pharmaceuticals. The vibrating screen achieves separation and screening by generating vibrations that cause materials to move on the screen surface.

[0003] The working principle of a vibrating screen is based on the interaction of vibration and gravity. When material is fed into the vibrating screen, the screen surface vibrates through an eccentric block driven by an electric motor or other vibration source. This vibration causes the material to jump, slide, or roll on the screen surface, thereby separating materials of different particle sizes through the screen openings.

[0004] Currently, in order to ensure that the vibrating screen can be set with two vibration points and that the vibration frequencies of the two vibration points are the same, a dual-axis connection is achieved through a core shaft connected by two eccentric blocks to achieve stable vibrating screening. This type of vibrating screen not only needs to ensure a stable vibration frequency, but also needs to adjust the tilt angle of the vibrating screen according to the type of material being screened during vibration to meet the actual vibrating screening requirements.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides a dual-axis linkage vibrating screen tilt angle adjustment structure, including: The screening mechanism 1 includes a side seat 10, a screening plate 11, a guide table 12, and screening holes 13. The side seats 10 are arranged in two sets and symmetrically distributed. The screening plate 11 for receiving materials is slidably sleeved inside the two side seats 10. The upper end of the side seat 10 is provided with a guide table 12 for assisting material feeding. The upper end of the guide table 12 has an inclined structure. The surface of the screening plate 11 is provided with a number of screening holes 13 for screening materials. The screening holes 13 on the surface of the screening plate 11 can be used for screening materials. The aperture of the screening holes 13 can be set according to actual needs. The guide table 12 plays an auxiliary role in receiving materials, so that the materials falling above the side seat 10 can slide down the inclined surface of the guide table 12 onto the screening plate 11. The tilt adjustment mechanism 2 includes a base 20, a support column 21, a hinge 22, a cylinder 23, a connecting seat 24, and a top ball 25. The base 20 has a U-shaped structure. Support columns 21 for supporting the side seat 10 are fixed to both ends of the base 20. The upper end of the support column 21 is equipped with a hinge 22. The rotating part of the hinge 22 is fixedly installed with the lower end of the side seat 10. The two ends of the base 20 are fixed with cylinders 23. The cylinder 23 is equipped with a piston rod for extension and retraction. The upper end of the piston rod is equipped with a connecting seat 24. The upper end of the connecting seat 24 is fixed with a top ball 25 for pushing the side seat 10. A ball is installed below the side seat 10 distributed along one side. There are two cylinders 23, which can be pneumatic or hydraulic cylinders, depending on the actual size of the screening plate 11. One of the two cylinders 23 can be used for normal pushing, and the other can be used for auxiliary pushing support after pushing. When it is necessary to adjust the angle of the screening plate 11, the piston rod of the cylinder 23 extends, so that the top ball 25 can push the side seat 10 to flip based on the hinge 22, so that the screening plate 11 changes from horizontal to inclined, and the inclination angle does not exceed 60 degrees. The top ball 25 is made of solid stainless steel, which can prevent the top ball 25 from deforming during pushing. At the same time, its arc surface can make smoother contact with the lower end of the side seat 10 during pushing.

[0020] The side seat 10 has several sleeves 14 fixedly installed inside. A reset rod 15 is slidably connected inside the sleeve 14. The end of the reset rod 15 away from the sleeve 14 is fixed to the side wall of the screening plate 11. When the screening plate 11 performs left and right reciprocating vibration screening, the reset rod 15 slides inside the sleeve 14, which can ensure the stability of the left and right movement of the screening plate 11 based on the side seat 10.

[0021] The surface of the reset rod 15 is covered with a spring 16. The two ends of the spring 16 are fixedly assembled with the end face of the sleeve 14 and the side of the screening plate 11, respectively. When the screening plate 11 vibrates back and forth, it is reset by the deformation of the spring 16, which can ensure the stable reset of the screening plate 11.

[0022] The lower end of the screening plate 11 is also provided with a vibration mechanism 3. The vibration mechanism 3 includes a bearing 30 and a mounting frame 32. The upper end of the bearing 30 and the upper end of the mounting frame 32 are assembled and fixed to the lower end of the screening plate 11. The bearing 30 and the mounting frame 32 are distributed along both sides of the screening plate 11, so that the two eccentric blocks 37 set below it have a certain interval.

[0023] The bearing 30 has a rotating drive shaft 31 inside, and a drive pulley 34 is fixedly sleeved on the surface of the drive shaft 31. The drive shaft 31 can rotate stably based on the bearing 30, and the drive pulley 34 can drive the drive shaft 31 to rotate under the transmission action of the belt 36.

[0024] The motor 33 is fixedly mounted on the inner side of the mounting bracket 32 ​​by a bracket. The motor 33 has a rotating shaft for driving inside, and the end of the rotating shaft is fixedly connected to the drive shaft 38 by a coupling. Eccentric blocks 37 are fixedly sleeved on the surface of the drive shaft 38 and the surface of the linkage shaft 31. After the motor 33 is powered on, its rotating shaft can rotate, thereby making the drive shaft 38 rotate synchronously.

[0025] The drive shaft 38 is fixedly fitted with a drive pulley 35, and a belt 36 passes over the surface of the drive pulley 35. The drive pulley 35 is also connected to the linkage pulley 34 through the belt 36. When it is necessary to make the two eccentric blocks 37 rotate synchronously to ensure the vibration screening efficiency of the screening plate 11, the power of the motor 33 is turned on, so that the motor 33 can drive the drive shaft 38 to rotate, and make the drive pulley 35 rotate. Through the transmission effect of the belt 36, the linkage pulley 34 rotates, so that the two eccentric blocks 37 can rotate synchronously, ensuring that the vibration frequency applied to the screening plate 11 is consistent.

[0026] In practice The screening mechanism 1 of this scheme achieves material screening through the synergistic action of the side seat 10 and the screening plate 11. The side seat 10 is symmetrically distributed and internally slides to connect with the screening plate 11. The screening holes 13 on the surface of the screening plate 11 can be adjusted according to the material characteristics to ensure screening accuracy. The upper end of the guide table 12 is a sloping structure, which can guide the material above the side seat 10 to the screening plate 11 to avoid accumulation. The left and right reciprocating vibration of the screening plate 11 is driven by the vibration mechanism 3. The rotation of the eccentric block 37 generates centrifugal force, which drives the screening plate 11 to vibrate laterally. The combination of the reset rod 15 and the spring 16 ensures vibration stability: the reset rod 15 slides in the sleeve 14 to limit the displacement range of the screening plate 11, and the elastic deformation of the spring 16 provides the reset force, so that the screening plate 11 returns to its position quickly. The tilt adjustment mechanism 2 changes the tilt angle of the screening plate 11 through the extension and retraction of the cylinder 23. The U-shaped structure of the base 20 supports the column 21. The upper end of the column 21 is connected to the side seat 10 through the hinge 22 to form a rotatable fulcrum. When the piston rod of the cylinder 23 extends, the top ball 25 pushes the lower end of the side seat 10, forcing the side seat 10 to rotate around the hinge 22, thereby adjusting the tilt angle of the screening plate 11, which does not exceed 60 degrees. The top ball 25 is made of solid stainless steel, and its arc surface design reduces friction with the side seat 10 to ensure smooth pushing. The dual cylinder configuration enhances stability: one cylinder is responsible for the main pushing, and the other provides auxiliary support to prevent the screening plate 11 from shifting during tilt adjustment. The vibration mechanism 3 drives the double eccentric blocks 37 to rotate synchronously via the motor 33, generating uniform vibration. The rotating shaft of the motor 33 is connected to the drive shaft 38 via a coupling. The drive shaft 38 drives the eccentric block 37 fixed on it to rotate. At the same time, the drive pulley 35 and belt 36 drive the linkage pulley 34 to rotate synchronously. The other eccentric block 37 on the linkage shaft 31 is distributed at intervals with the eccentric block 37 on the drive shaft 38 to ensure the balance of vibration force. The bearing 30 and the mounting bracket 32 ​​are respectively fixed to the lower end of the screening plate 11 to provide stable support for the linkage shaft 31 and the drive shaft 38. The synchronous rotation of the double eccentric blocks 37 generates directional vibration force, which drives the screening plate 11 to reciprocate left and right. With the elastic reset of the spring 16, an efficient and stable screening operation is formed.
