Description

Technical Field

[0001] This utility model relates to the field of sieve plate skeleton technology, specifically a rubber sieve plate skeleton structure. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. It can be divided into metallic minerals and non-metallic minerals. In the process of ore production and processing, it is necessary to extract and smelt the minerals inside the ore. To facilitate processing, the ore usually needs to be crushed and screened. Ore screening requires screening through screen plates on a vibrating screen. The screen plates need to be supported by a frame to increase the stability of the screen plate installation.

[0003] Chinese Utility Model Patent Publication No. CN222197841U discloses a rubber screen plate skeleton structure. This rubber screen plate skeleton structure facilitates the assembly and installation of the main skeleton and vibration device by setting a fixing plate with fixing holes. The cooperation of the connecting plate helps to stably support the screen plate assembly installed in the retaining ring. The setting of a limiting plate with connecting rods and the cooperation of multiple connecting rods and fixing bolts increase the stability of the installation of the limiting plate and the main skeleton. However, this rubber screen plate skeleton structure is not convenient to adjust the length according to different working conditions, which easily leads to its great limitations. It is not convenient to select its length to cope with different working conditions, and it is not convenient to promote its use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rubber screen plate skeleton structure, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a rubber screen frame structure, including a frame frame, with mounting grooves at both the upper and lower ends and slots at the four corners. There are two frames. One frame has slots on both sides. A first positioning screen adapted to the mounting groove is provided on the inner surface of the frame frame. Positioning blocks adapted to the slots are fixedly installed at the four corners of the first positioning screen. A second positioning screen is provided on the inner surface of the other frame frame. Limiting blocks and extension blocks adapted to the positioning blocks are fixedly installed at the four corners of the second positioning screen. The extension blocks pass through the slots and are inserted into the slots of one of the frame frames.

[0006] Preferably, both sides of the two skeleton frames are provided with connecting grooves, and the two skeleton frames are connected to a connecting frame through the connecting grooves. The outer side of the connecting frame is provided with a second positioning hole, and the connecting frame is fixedly installed with a second positioning bolt through the second positioning hole.

[0007] Through the above technical solution, by designing a connecting groove, after the two skeleton frames are spliced ​​together, a connecting frame can be inserted into the connecting groove to limit the position of the two skeleton frames.

[0008] Preferably, the second positioning bolt passes through the connecting frame and the two skeleton frames and extends to their bottom, and there are multiple identical second positioning bolts distributed at equal intervals.

[0009] Through the above technical solution, multiple second positioning bolts that are equidistantly distributed and penetrate the bottom of the connecting frame and the two skeleton frames can fasten the connecting frame and the skeleton frame at multiple positions. Compared with a single positioning bolt, this greatly enhances the stability of the connection and further prevents the two skeleton frames from relative displacement or loosening due to external impacts, vibrations, or other factors during use. This ensures the stability of the entire rubber screen frame structure and extends its service life.

[0010] Preferably, a reinforcing rail is fixedly installed on the side of the skeleton frame near the mounting groove, and the reinforcing rail has a cross-shaped structure.

[0011] Through the above technical solution, the cross-shaped reinforcing rail significantly enhances the structural strength of the skeleton frame near the mounting groove. After the first or second positioning screen is installed, the reinforcing rail can better withstand the pressure from the screen plate and the impact force generated during the screening process, effectively preventing the skeleton frame from deforming in this part, thereby ensuring the shape stability of the entire rubber screen plate skeleton structure, providing solid and reliable support for the normal operation of the screen plate, and improving the overall performance and durability of the rubber screen plate.

[0012] Preferably, the first positioning screen has a plurality of first screen holes distributed at equal intervals from top to bottom, and the second positioning screen has a plurality of second screen holes distributed at equal intervals from top to bottom, and the first screen holes and the second screen holes have the same structure.

[0013] Through the above technical solution, the first and second screen holes with equal spacing can ensure that the material is subjected to uniform screening when passing through the rubber screen plate. The screen holes with the same structure make the two positioning screens consistent in screening efficiency and effect. No matter whether the material enters from the first positioning screen or the second positioning screen, a stable and standard screening result can be obtained, which effectively improves the screening quality and accuracy of the rubber screen plate.

[0014] Preferably, the extension block and the slot are located on the same horizontal line, and the extension block abuts against the positioning block.

[0015] Through the above technical solution, the extension block and the slot are on the same horizontal line, ensuring that the extension block can be smoothly and accurately inserted into the slot, realizing an effective connection between the two skeleton frames. The extension block and the positioning block abut against each other, further enhancing the stability of the connection part of the two skeleton frames. This makes the force on the connection part more uniform after the two skeleton frames are spliced, and it is not easy to have structural instability problems caused by loose connection or misalignment, thus ensuring the integrity and reliability of the rubber screen frame structure during use.

[0016] Preferably, the extension block has a positioning hole from top to bottom, and a first positioning bolt is provided on the outer surface of the extension block. The first positioning bolt passes through the positioning hole and the positioning block and extends to the inner surface of the skeleton frame.

[0017] Through the above technical solution, the first positioning bolt passes through the positioning hole of the extension block and the positioning block and extends to the inner surface of the skeleton frame, firmly fixing the extension block and the positioning block together, thereby making the connection between the two skeleton frames more solid. This not only increases the tensile and shear resistance of the connection part, but also effectively prevents the connection from loosening due to vibration or material impact during equipment operation, ensuring that the rubber screen plate skeleton structure remains stable during long-term use, and providing a reliable structural foundation for the efficient screening operation of the rubber screen plate.

[0018] Compared with the prior art, this utility model provides a rubber screen plate skeleton structure with the following features:

[0019] Beneficial effects:

[0020] 1. The cross-shaped reinforcing bars of this rubber screen frame significantly enhance the structural strength of the frame frame near the mounting groove, effectively preventing deformation of the frame frame due to stress during screen installation and screening, ensuring the shape stability of the entire rubber screen frame structure, and improving overall performance and durability.

[0021] 2. The rubber screen frame structure, through the design of limiting blocks and extension blocks, allows the two frame frames to be assembled according to the actual working length. Then, it is fixed with connecting frames and positioning bolts. This not only allows the length to be adjusted according to different working lengths, but also prevents it from falling off easily, improving its practicality and making it easy to promote and use.

Detailed Implementation

[0029] 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.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides a rubber screen frame structure, including a frame frame 1. The frame frame 1 has mounting grooves 2 at both the top and bottom ends and slots 3 at the four corners. There are two frame frames 1. One frame frame 1 has slots 4 on both sides. The inner surface of the frame frame 1 is provided with a first positioning screen 6 that matches the mounting groove 2. Positioning blocks 8 that match the slots 3 are fixedly installed at the four corners of the first positioning screen 6. The inner surface of the other frame frame 1 is provided with a second positioning screen 9. Limiting blocks 11 and extension blocks 12 that match the positioning blocks 8 are fixedly installed at the four corners of the second positioning screen 9. The extension blocks 12 pass through the slots 4 and are inserted into the slots 4 of one frame frame 1.

[0031] Specifically, both sides of the two skeleton frames 1 are provided with connecting grooves 15. The two skeleton frames 1 are connected to a connecting frame 16 by inserting it through the connecting grooves 15. The outer side of the connecting frame 16 is provided with a second positioning hole 17. The connecting frame 16 is fixedly installed with a second positioning bolt 18 through the second positioning hole 17. The advantage is that, through the design of the connecting grooves 15, when the two skeleton frames 1 are spliced, the connecting frame 16 can be inserted into the connecting grooves 15 to limit the position of the two skeleton frames 1.

[0032] Specifically, the second positioning bolt 18 passes through the connecting frame 16 and the two skeleton frames 1 and extends to their bottom. Multiple second positioning bolts 18 are provided and are distributed at equal intervals. The advantage is that multiple second positioning bolts 18 distributed at equal intervals and passing through the bottom of the connecting frame 16 and the two skeleton frames 1 can fasten the connecting frame 16 and the skeleton frames 1 at multiple positions. Compared with a single positioning bolt, this greatly enhances the stability of the connection and further prevents the two skeleton frames 1 from relative displacement or loosening due to external impact, vibration and other factors during use. This ensures the stability of the entire rubber screen frame structure and extends its service life.

[0033] Specifically, a reinforcing rail 5 is fixedly installed on the side of the skeleton frame 1 near the mounting groove 2. The reinforcing rail 5 has a cross-section in the shape of a cross. The advantage is that the cross-section of the reinforcing rail 5 significantly enhances the structural strength of the skeleton frame 1 near the mounting groove 2. After the first positioning screen 6 or the second positioning screen 9 is installed, the reinforcing rail 5 can better withstand the pressure from the screen plate and the impact force generated during the screening process, effectively preventing the skeleton frame 1 from deforming in this part, thereby ensuring the shape stability of the entire rubber screen plate skeleton structure, providing solid and reliable support for the normal operation of the screen plate, and improving the overall performance and durability of the rubber screen plate.

[0034] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the first positioning screen 6 has multiple first screen holes 7 evenly distributed from top to bottom, and the second positioning screen 9 has multiple second screen holes 10 evenly distributed from top to bottom. The first screen holes 7 and the second screen holes 10 have the same structure. The advantage is that the evenly distributed first screen holes 7 and the second screen holes 10 can ensure that the material is uniformly screened when passing through the rubber screen plate. The screen holes with the same structure make the two positioning screens consistent in screening efficiency and effect. No matter whether the material enters from the first positioning screen 6 or the second positioning screen 9, a stable and standard screening result can be obtained, which effectively improves the screening quality and accuracy of the rubber screen plate.

[0036] Specifically, the extension block 12 and the slot 4 are located on the same horizontal line, and the extension block 12 abuts against the positioning block 8. The advantage is that the extension block 12 and the slot 4 are on the same horizontal line, which ensures that the extension block 12 can be smoothly and accurately inserted into the slot 4, realizing an effective connection between the two skeleton frames 1. The abutment between the extension block 12 and the positioning block 8 further enhances the stability of the connection part of the two skeleton frames 1, making the force on the connection part more uniform after the two skeleton frames 1 are spliced, and it is not easy to have structural instability problems caused by loose connection or misalignment, thus ensuring the integrity and reliability of the rubber screen frame structure during use.

[0037] Specifically, the extension block 12 has a positioning hole 13 from top to bottom, and a first positioning bolt 14 is provided on the outer surface of the extension block 12. The first positioning bolt 14 passes through the positioning hole 13 and the positioning block 8 and extends to the inner surface of the skeleton frame 1. The advantage is that the first positioning bolt 14 passes through the positioning hole 13 of the extension block 12 and the positioning block 8 and extends to the inner surface of the skeleton frame 1, which firmly fixes the extension block 12 and the positioning block 8 together, thereby making the connection between the two skeleton frames 1 more solid. This not only increases the tensile and shear resistance of the connection part, but also effectively prevents the connection from loosening due to vibration or material impact during equipment operation, ensuring that the rubber screen plate skeleton structure remains stable during long-term use, and providing a reliable structural foundation for the efficient screening of the rubber screen plate.

[0038] Working principle: In use, two skeleton frames 1 are spliced ​​together through a specific structure. The slots 4 on both sides of one skeleton frame 1 are inserted into the extension blocks 12 fixed at the four corners of the other skeleton frame 1. The extension blocks 12 and the slots 4 are on the same horizontal line, ensuring precise alignment. At the same time, the extension blocks 12 abut against the positioning blocks 8 at the four corners of the first positioning screen 6, further stabilizing the connection. In addition, connecting frames 16 are inserted into the connecting slots 15 opened on both sides of the two skeleton frames 1, and are secured by the second positioning holes 17 through the connecting frames 16 and the multiple equidistant second positioning bolts 18 at the bottom of the two skeleton frames 1. The two frame frames 1 are now securely connected from all directions and multiple angles. The first positioning screen 6 is installed on the inner surface of one frame frame 1 by matching the mounting grooves 2 at the upper and lower ends of the frame frame 1 and by the cooperation of the positioning blocks 8 and the slots 3 at the four corners. The second positioning screen 9 is installed on the inner surface of the other frame frame 1 in a similar manner. During installation, the reinforcing rails 5 provide support for the screen plate. The material is screened through the first screen hole 7 of the first positioning screen 6 or the second screen hole 10 of the second positioning screen 9. Since the first screen hole 7 and the second screen hole 10 are evenly distributed and have the same structure, the material can be uniformly screened when passing through the screen plate.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
