Description

Technical Field

[0001] This utility model relates to the field of vibrating screen plate technology, and in particular to a vibrating screen plate that is easy to maintain. Background Technology

[0002] Easy-to-maintain vibrating screen plates are widely used in mining and mineral processing for screening large quantities of ore, thanks to their quick replacement and convenient maintenance features. They can quickly replace worn parts under high-load operation to maintain efficient production. In the field of sand and gravel aggregate processing, they can adapt to the screening needs of sand and gravel of different particle sizes, and their simple maintenance reduces downtime and improves the operating rate of the production line.

[0003] In the existing technology, some easy-to-maintain vibrating screen plates are based on the principle of vibrating screening. The vibration generated by the vibrator is transmitted to the screen plate, causing the screen plate to vibrate at high frequency. The material jumps forward on the screen plate under the action of vibration, and the material smaller than the screen hole size falls through the screen hole to complete the screening.

[0004] However, in actual use, due to the inability to self-adapt to installation, the screen plate may need to be forcibly fixed by means of forceful hammering or adjusting bolt torque during maintenance and replacement. This will aggravate the plastic deformation of components such as the screen plate frame and screen frame groove. In order to address the above problems, a vibrating screen plate that is easy to maintain is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-maintain vibrating screen plate, aiming to improve the problem that some easy-to-maintain vibrating screen plates in the prior art cannot be adaptively installed on the machine.

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

[0007] An easy-to-maintain vibrating screen plate includes a screen plate body, an extension plate fixedly connected to the outside of the screen plate body, multiple self-adaptive mounting mechanisms fixedly connected to the upper and lower ends of the extension plate, and wear-resistant mechanisms fixedly connected to the upper and lower ends of the outside of the screen plate body.

[0008] The adaptive installation mechanism includes a connecting frame, with multiple rotating plates rotatably connected inside the connecting frame. A connecting frame is rotatably connected to the other end of each rotating plate. A damping slider is fixedly connected to the bottom of the connecting frame. A clamping plate is slidably connected to the outside of the damping slider. A groove is provided inside the clamping plate, and a reset component is provided inside the groove.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a fixing rod, which is externally fixedly connected to the inside of the clamping plate, and a mounting spring is sleeved on the outside of the fixing rod;

[0011] As a further description of the above technical solution:

[0012] The wear-resistant mechanism includes a wear-resistant liner plate. The wear-resistant liner plate is fixedly connected to the upper and lower ends of the screen plate body. The wear-resistant liner plate is provided with a wear-resistant layer inside. A buffer layer is fixedly connected to the bottom of the wear-resistant layer. A reinforcing layer is fixedly connected to the bottom of the buffer layer.

[0013] As a further description of the above technical solution:

[0014] The buffer layer is externally fixedly connected to the inside of the wear-resistant liner, and the reinforcement layer is externally fixedly connected to the inside of the wear-resistant liner;

[0015] As a further description of the above technical solution:

[0016] The clamping plate has multiple resistance grooves on its outside, and the rotating plate is rotatably connected to the outside of the extension plate.

[0017] As a further description of the above technical solution:

[0018] The wear-resistant liner is fixedly connected to the four outer corners with mounting bolts, and the mounting bolts are externally fixedly connected to the four outer corners of the screen plate body.

[0019] As a further description of the above technical solution:

[0020] The damping slider is internally slidably connected to the outside of the fixed rod, and the rotating plate is externally rotatably connected to the outside of the extension plate;

[0021] As a further description of the above technical solution:

[0022] One end of the mounting spring is fixedly connected to the inside of the slide groove, and the other end of the mounting spring is fixedly connected to the outside of the damping slider.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the design uses a pressing clamp to squeeze the rotating plate, which in turn drives the damping slider to compress the installation spring, creating installation space. After the clamp is released, the spring rebounds, allowing the clamp to adaptively clamp the machine slot. With the help of spring elasticity and damping buffer, the screen plate can be installed quickly without tools, and it can automatically adapt to screen plates of different sizes, ensuring a stable installation. This not only improves the maintenance efficiency of the vibrating screen, but also reduces the damage to the connection parts caused by vibration through elastic clamping, thus extending the service life of the equipment.

[0025] 2. In this utility model, the screen plate adopts a three-layer composite structure. The wear-resistant layer is made of high-hardness material to resist scratching and impact, disperse external force and extend service life; the buffer layer uses elastic material to absorb energy and reduce vibration, reduce impact transmission and reduce friction and loosening; the reinforcing layer uses high-strength metal to evenly distribute the load, prevent deformation and breakage, maintain screen hole accuracy, and the three layers work together to improve the wear resistance, vibration resistance and structural stability of the screen plate and extend its service life.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of an easy-to-maintain vibrating screen plate, comprising a screen plate body 1. The screen plate body 1 has high structural strength and can withstand the impact and friction of materials during the screening process, ensuring that the screen plate is not easily deformed or damaged during long-term use. It is the foundation for realizing the material screening function. An extension plate 2 is fixedly connected to the outside of the screen plate body 1. The extension plate 2 can enhance the strength of the edge of the screen plate body 1, prevent the screen plate from breaking due to concentrated force on the edge during use, and extend the service life of the screen plate. Multiple self-adaptive mounting mechanisms 3 are fixedly connected to the upper and lower ends of the extension plate 2. Wear-resistant mechanisms 5 are fixedly connected to the upper and lower ends of the screen plate body 1. The wear-resistant mechanism 5 includes a wear-resistant liner 51, which directly bears the friction and impact of materials during the screening process, protecting the screen plate body 1 from damage. Wear-resistant liner 51 has good wear resistance and impact resistance, and can maintain a long service life even in harsh working environments, reducing the frequency of screen plate replacement and reducing maintenance costs. The wear-resistant liner 51 is externally fixed to the upper and lower ends of the screen plate body 1. The wear-resistant liner 51 is provided with a wear-resistant layer 52 inside. The wear-resistant layer 52 is attached to the inner surface of the wear-resistant liner 51 by processes such as thermal spraying, sintering or bonding. Its surface hardness is extremely high, which can effectively resist the wear of materials and further improve the wear resistance of the wear-resistant liner 51. A buffer layer 53 is fixedly connected to the bottom of the outer side of the wear-resistant layer 52. The buffer layer 53 has a moderate thickness and can play a buffering role when materials impact the wear-resistant layer 52, reducing the impact force on the wear-resistant layer 52 and the wear-resistant liner 51. Meanwhile, the buffer layer 53 can also absorb the vibration energy generated by the vibrating screen during operation, reduce the vibration amplitude of the screen plate, reduce the resonance phenomenon between the screen plate and other components, improve the working stability and service life of the screen plate. The bottom of the buffer layer 53 is fixedly connected to the reinforcing layer 54. The reinforcing layer 54 can evenly disperse the impact force and vibration energy of the material, improve the load-bearing capacity of the wear-resistant mechanism 5, ensure that the wear-resistant mechanism 5 maintains good performance during long-term use, and provide reliable protection for the screen plate body 1. The buffer layer 53 is fixedly connected to the inside of the wear-resistant liner 51, and the reinforcing layer 54 is fixedly connected to the inside of the wear-resistant liner 51.

[0034] The adaptive installation mechanism 3 includes a connecting frame 31, with multiple rotating plates 32 rotatably connected inside the connecting frame 31. This provides a stable rotational support foundation for the rotating plates 32 and transfers the load of the screen plate body 1 to the entire installation mechanism. A connecting frame 33 is rotatably connected to the other end of each rotating plate 32. The connecting frame 33 is connected to the connecting frame 31 via the rotating plates 32, forming a movable four-bar linkage. During screen plate installation, the connecting frame 33 can adjust its position as the rotating plates 32 rotate, allowing the damping slider 34 to accurately slide into the groove 36 of the clamping plate 35. The bottom of the connecting frame 33 is fixedly connected to the damping slider 34. The main function of block 34 is to transfer the vibration load of the screen plate to clamping plate 35 and to achieve lateral positioning of the screen plate through cooperation with slide groove 36. The external sliding connection of damping slider 34 is clamping plate 35. The function of clamping plate 35 is to provide sliding track for damping slider 34 and to apply preload to screen plate through reset component 37 to ensure that screen plate does not shift during vibration. Dust covers are designed on both sides of clamping plate 35 to prevent dust from entering slide groove 36 and affecting sliding performance of damping slider 34. Slide groove 36 is opened inside clamping plate 35. Lubricating oil groove is designed at the bottom of slide groove 36, which can be injected with grease periodically to reduce sliding friction resistance. During the installation of the screen plate, the slide groove 36 provides precise guidance for the damping slider 34, ensuring that the screen plate can be accurately installed in place. The slide groove 36 is equipped with a reset component 37, which includes a fixing rod 371. The function of the fixing rod 371 is to provide support and guidance for the installation spring 372, ensuring that the spring does not bend or shift during compression and extension. The fixing rod 371 is externally fixedly connected to the inside of the clamping plate 35, and the installation spring 372 is sleeved on the outside of the fixing rod 371. The damping slider 34 slides along the slide groove 36 and compresses the installation spring 372. The elastic force generated by the spring is transmitted to the screen plate through the damping slider 34 and the connecting frame 33, so that the screen plate fits tightly with the vibrating screen body.

[0035] Reference Figures 2 to 4The clamping plate 35 has multiple resistance grooves 4 on its exterior. The function of the resistance grooves 4 is to cooperate with the corresponding protrusions on the vibrating screen body after the screen plate is installed in place, forming a mechanical locking effect to prevent the clamping plate 35 from sliding relative to the screen plate during vibration, thereby further enhancing the stability of the screen plate installation. The rotating plate 32 is externally rotatably connected to the exterior of the extension plate 2. The four corners of the wear-resistant liner 51 are fixedly connected with mounting bolts 6. The mounting bolts 6 not only firmly fix the wear-resistant liner 51 to the screen plate body 1, enabling it to effectively withstand the friction and impact of the material, but also protect the screen plate body. 1. Furthermore, during the installation process, the installation position of the wear-resistant liner 51 can be finely adjusted by adjusting the tightening degree of the mounting bolts 6 to ensure that it fits tightly with the screen plate body 1, thereby improving the protective effect and service life of the wear-resistant liner 51. The mounting bolts 6 are externally fixedly connected to the four external corners of the screen plate body 1. The damping slider 34 is internally slidably connected to the outside of the fixed rod 371. The rotating plate 32 is externally rotatably connected to the outside of the extension plate 2. One end of the mounting spring 372 is fixedly connected to the inside of the slide groove 36, and the other end of the mounting spring 372 is fixedly connected to the outside of the damping slider 34.

[0036] Working principle: When installing the screen plate body 1, by pressing the clamping plate 35, the clamping plate 35 is in a squeezed state, which allows the clamping plate 35 to squeeze the rotating plate 32. The rotating plate 32 squeezes the mounting spring 372 through the damping slider 34, which in turn allows the screen plate body 1 to be placed inside the vibrator. When it is placed in the appropriate position, by releasing the clamping plate 35, the mounting spring 372 rebounds, thereby achieving self-adaptive installation of the screen plate body 1.

[0037] The outermost wear-resistant layer 52 is made of high-hardness material. Its surface hardness resists the scraping, cutting and impact of materials, disperses the impact force to avoid excessive local wear, and extends the service life of the screen plate. The middle buffer layer 53 is made of elastic materials such as rubber and sponge. When materials impact and the screen body vibrates, it absorbs and dissipates energy through elastic deformation, reduces the transmission of impact force, attenuates vibration, and reduces friction and loosening between the screen plate and the screen frame. The innermost reinforcing layer 54 is made of high-strength metal material. Its reasonable mechanical structure evenly distributes the load, prevents the screen plate from deforming and breaking, and maintains the shape of the screen plate and the accuracy of the screen holes.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
