Description

Technical Field

[0001] The present application relates to the technical field of material screening, and in particular to a high-compatibility vibrating screen device. Background Art

[0002] In the field of material screening technology, vibrating screens are widely used in various industrial production processes due to their high efficiency and stability. This type of equipment significantly improves production efficiency and product quality, especially when processing large quantities and diverse materials. With the continuous advancement of industrial production, the requirements for material screening accuracy are also gradually increasing, which has prompted the development and improvement of screening technology. However, how to improve the adaptability and flexibility of vibrating screen equipment while maintaining screening accuracy has become a key issue.

[0003] Traditional vibrating screens primarily use single or multi-layer screens to classify materials to meet varying production needs. To accommodate the screening requirements of materials with varying particle sizes, different screen sizes are often required. Existing technologies primarily include linear vibrating screens, circular vibrating screens, and vibrating screens with automatic screen-changing capabilities. While these methods can meet changing screening requirements to a certain extent, they still have certain limitations.

[0004] A Chinese patent with announcement number CN221790060U discloses a vibrating screen device, including a base, with columns fixedly connected at the four corners of the top of the base, shock-absorbing springs fixedly connected to the top of the columns, a screen box fixedly connected to the top of the shock-absorbing springs, a vibration motor fixedly connected to the bottom of the screen box, a linear motor fixedly connected to the outer wall of the screen box, a driving end of the linear motor passes through the screen box and is fixedly connected to a lifting door, a screen is provided inside the screen box, positioning strips are provided on both sides of the inner wall of the screen box, and driving mechanisms corresponding to the screen are provided on both sides of the outer wall of the screen box.

[0005] The above-mentioned vibrating screen device utilizes the mutual cooperation between the motor, the conveying wheel and the positioning bar. The motor drives the rotation of multiple conveying wheels, which can drive the screen to automatically slide in and out of the screen box, making it convenient for auxiliary staff to replace the screen. In actual application, replacing the screen often requires more time and manpower, and with the improvement of the degree of automation, facing materials with diverse particle sizes and certain special shapes, it is necessary to prepare several screens of different specifications in advance, which increases the equipment cost accordingly. In addition, when faced with diversified materials, conventional vibrating screen equipment is difficult to quickly adapt to changes in demand, resulting in limited overall production efficiency. Especially in the process of replacing the screen, the frequent use of motor assistance not only increases maintenance costs, but also reduces the flexibility of the equipment when facing diversified materials. Utility Model Content

[0006] In order to improve the flexibility of the vibrating screen in adjusting the screening standard, the present application provides a high-compatibility vibrating screen device.

[0007] The highly compatible vibrating screen equipment provided in this application adopts the following technical solutions:

[0008] A highly compatible vibrating screen device comprises a frame with an inclined top surface, a plurality of parallel filter rods distributed on the top of the frame along its own length direction, each of the filter rods is inclined along the inclined direction of the top surface of the frame, a mounting hole is opened on the frame corresponding to each filter rod, the upward inclined rod body of the filter rod slides through the corresponding mounting hole, and a positioning piece is provided on the end of each filter rod extending out of the mounting hole, which abuts against the side wall of the frame, a screen is provided on the frame directly below the plurality of filter rods, and a vibration motor for driving the screen to vibrate is provided on the frame of the screen.

[0009] By adopting the above technical solution, the highly compatible vibrating screen equipment can achieve efficient material screening. When the vibrating motor is started, the material first falls onto the inclined filter rod, where it is screened for the first time. The material after the first screening then falls onto the vibrating screen and passes through the screen under the vibration of the screen, thus achieving a secondary screening. The filter rod used for the primary screening has its end inserted into the frame and fixed to the frame by positioning parts. The staff can adjust the size of the material screened for the first time as needed by removing the spaced filter rods, thereby improving the flexibility of the equipment in adjusting the screening standard.

[0010] Optionally, the filter rods on the frame are arranged in two rows in parallel along the vertical direction, and the filter rods in the lower row are located directly below the corresponding filter rods in the upper row.

[0011] By adopting this technical solution, when material falls onto the upper filter bars, the upper filter bars deform to a certain extent due to the downward pressure of the material. The deformed upper filter bars collide with the lower filter bars, which are stationary relative to the frame. The resulting vibration reduces the possibility of material getting stuck between adjacent filter bars. This allows for more efficient primary screening of the material, improving its efficiency and accuracy, as well as the uniformity of material distribution.

[0012] Optionally, a through hole is provided on the end of the filter rod extending out of the mounting hole perpendicular to its own length direction, the positioning member is a safety pin inserted into the through hole, and the safety pin is arranged to interfere with the side wall of the frame.

[0013] By adopting the above technical solution, the through hole on the end of the filter rod extending out of the mounting hole cooperates with the safety pin as a positioning piece, so that the filter rod can be firmly positioned on the frame. At the same time, it is convenient for the staff to flexibly adjust the number and position of the filter rods according to the screening requirements, thereby adjusting the distance between two adjacent filter rods in the horizontal direction, and improving the flexibility of the vibrating screen equipment in adjusting the screening standard.

[0014] Optionally, one vibration motor is provided on both sides of the screen along the length direction of the frame, and elastic vibration supports are also provided on both sides of the screen along the length direction of the frame. The elastic vibration supports are connected to the opposite side walls of the screen and the frame, and one elastic vibration support is provided on the same side on both sides of the vibration motor.

[0015] By adopting the above technical solution, the setting of elastic vibration support not only improves the uniformity and stability of screen vibration, but also improves the secondary screening effect and screening accuracy of the material, and reduces the wear and noise caused to the frame during the vibration of the screen, thereby significantly improving the working performance of the vibrating screen equipment.

[0016] Optionally, a protective cover covering the vibration motor and elastic vibration support on the same side is provided on both sides of the frame along its own length direction, the screen is clamped between the two protective covers, and the protective covers are located below the filter rod.

[0017] By adopting this technical solution, the protective covers installed on both sides of the frame effectively protect the vibration motor and elastic vibration support on the same side, preventing them from being damaged by external factors. At the same time, the screen is clamped between the two protective covers, improving the stability of the screen position and thus the reliability of the screening process. The design of the protective cover below the filter rod makes the entire equipment structure more compact and reasonable, and optimizes the spatial layout.

[0018] Optionally, the top of each protective cover is provided with a guide surface inclined toward the screen.

[0019] By adopting the above technical solution, the setting of the guide surface can effectively guide the material that has passed the first screening to flow smoothly to the screen when it falls onto the protective cover, reducing the possibility of material accumulation on the top of the protective cover, thereby improving the material flow efficiency and simplifying the cleaning work of the vibrating screen equipment.

[0020] Optionally, a plurality of lifting ears are provided on the top of the frame on both sides of the distribution direction of the plurality of filter rods, and the plurality of lifting ears are symmetrically distributed on both sides of the frame.

[0021] By adopting the above technical solution, the multiple lifting ears arranged on both sides of the top of the frame can facilitate the lifting and transportation of the vibrating screen equipment, thereby improving the convenience of equipment installation and movement.

[0022] Optionally, a thread is provided on the end of the filter rod extending out of the mounting hole, and the positioning member is an end cap which is rotatably sleeved on the end of the filter rod by the thread and is easy to hold, and the end cap is arranged to interfere with the side wall of the frame.

[0023] By adopting the above technical solution, the end of the filter rod extending from the mounting hole is threaded and connected to the end cap, allowing the end cap to be easily rotated and tightened on the filter rod by hand, thereby limiting the tilted filter rod to the frame and achieving stable positioning of the filter rod. This design not only simplifies the installation and removal process of the filter rod, but also improves the convenience and safety of operation, thereby enhancing the flexibility and adaptability of the vibrating screen equipment when adjusting the screening standard.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. High-compatibility vibrating screen equipment can achieve efficient material screening. When the vibrating motor is started, the material first falls on the inclined filter rod, and the filter rod is used to achieve the first material screening; then the material after the first screening falls onto the vibrating screen, and passes through the screen under the vibration of the screen, thus achieving a secondary screening. The filter rod used for the primary screening has its end passed through the frame and fixed to the frame by positioning parts. The staff can adjust the size of the material screened at the first time as needed by removing the spaced filter rods, thereby improving the flexibility of the equipment in adjusting the screening standard;

[0026] 2. When the material falls onto the upper filter rods, they deform to a certain extent due to the downward pressure of the material. The deformed upper filter rods collide with the lower filter rods, which are stationary relative to the frame. The resulting vibration reduces the possibility of material getting stuck between adjacent filter rods, thus more effectively performing the primary screening of the material, improving the efficiency and accuracy of the primary screening, and the uniformity of material distribution.

[0027] 3. The through hole on the end of the filter rod extending out of the mounting hole cooperates with the safety pin as a positioning piece, so that the filter rod can be firmly positioned on the frame. At the same time, it is convenient for the staff to flexibly adjust the number and position of the filter rods according to the screening requirements, thereby adjusting the distance between two adjacent filter rods in the horizontal direction, and improving the flexibility of the vibrating screen equipment in adjusting the screening standard.

[0036] The embodiments of the present application disclose a highly compatible vibrating screen device.

[0040] Reference Figure 1 and Figure 2 The filter rods 2 on the frame 1 are arranged in two rows in parallel along the vertical direction, and the filter rods 2 in the lower row are located directly below the corresponding filter rods 2 in the upper row. Each filter rod 2 is arranged at an angle along the inclination direction of the top surface of the frame 1. A mounting hole 11 is opened on the frame 1 corresponding to each filter rod 2. The upwardly inclined rod body of the filter rod 2 slides through the corresponding mounting hole 11, and a positioning member 5 is provided at the end of each filter rod 2 extending out of the mounting hole 11, which abuts against the side wall of the frame 1.

The positioning member 5 in this embodiment is a safety pin 51 inserted into the through hole 21, and the safety pin 51 is arranged to abut against the side wall of the frame 1.

[0041] Reference Figure 1 and Figure 3 Elastic vibration supports 6 are installed between the inner sidewalls of the frame 1 and the screen 3 along both sides of the frame 1 along its length. Two elastic vibration supports 6 are located on the same side, one on each side of the vibration motor 4. A protective cover 7 is fixedly installed on both sides of the frame 1 along its length.

[0043] The implementation principle of a highly compatible vibrating screen device according to an embodiment of the present application is as follows: the vibrating motor 4 is activated, and the material falls onto the filter rod 2, where it undergoes a primary screening; the material after the primary screening then falls onto the vibrating screen 3, where it passes through the screen 3 under the vibration of the screen 3, thereby achieving a secondary screening.
