[0017] Beneficial Effects

[0018] The utility model provides a high-performance vibrating rubber screen for mines. Compared with the prior art, it has the following beneficial effects:

[0019] 1. The high-performance vibrating rubber screen for mines can be fixed on the vibrating equipment and installed on the support ring through the positioning frame. Then, the support ring can stably support the screening component and can be installed and fixed in conjunction with the limit component, thereby improving the stability of the use of the screening component. Then, the screening component can be used to screen and filter the ore and reduce the wear of the ore on it. At the same time, it can also increase the rebound force of the material, avoid ore scaling, and improve the screening efficiency.

[0020] 2. The high-performance vibrating rubber screen for mines can not only clamp the wear-resistant rubber plate through the support ring and the pressure ring in the screening assembly, but also stably clamp and fix the wear-resistant rubber plate through multiple first step holes and multiple connecting bolts, thereby improving the stability of the wear-resistant rubber plate. Since multiple screening holes are provided on the top surface of the wear-resistant rubber plate, and the multiple screening holes are distributed in a rectangular array, and each of the screening holes is arranged in an inclined manner, and the inner diameter of each screening hole is the same, the wear-resistant rubber plate and the screening holes can not only screen the ore, but also reduce the ore. It can reduce noise during screening and improve its wear resistance, thereby increasing its service life. At the same time, due to the good resilience of the wear-resistant rubber plate, it can increase the rebound force of the material, avoid mineral scale, and improve the screening efficiency. The wear-resistant rubber plate is flexible, and the probability of ore stuck in the screening hole is extremely small. Under the same screening hole rate conditions, the screening hole yield is more than 1.3 times that of the steel mesh, and the service life is long, generally 15 to 20 times that of ordinary steel screens. At the same time, due to the design of the screening hole is inclined, when the maximum size of the ore passes through the constraint part of the screening hole, it will automatically slide down, thereby realizing the process of 0 hole blockage.

[0021] 3. The high-performance vibrating rubber screen of the mine can provide space for the second step hole through the limit ring in the limit assembly, and can be fixed to the top surface of the support ring through the second step hole and the positioning screw, so as to achieve the purpose of limiting and fixing the screening assembly, thereby improving the stability of the use of the screening assembly. Then, the second step hole can be sealed by the rubber plug, thereby reducing the damage of the ore to the positioning screw and increasing the service life of the positioning screw.

[0030] Through the positioning frame 1, it can be fixed on the vibration equipment and the support ring 3 can be installed and fixed. Then, through the support ring 3, the screening component 2 can be stably supported and the limiting component 4 can be cooperated to install and fix the screening component 2, thereby improving the stability of the use of the screening component 2. Then, through the screening component 2, the ore can be screened and filtered, and the wear of the ore on it can be reduced. At the same time, the rebound force of the material can be increased, the mineral scale can be avoided, and the screening efficiency can be improved.

[0031] See also Figure 3 , Figure 4 The screening component 2 includes a wear-resistant rubber plate 21, and a plurality of screening holes 22 are provided on the top surface of the wear-resistant rubber plate 21, and the plurality of screening holes 22 are distributed in a rectangular array; a support ring 23 and a pressure ring 24 are provided on the bottom and bottom surface of the wear-resistant rubber plate 21, respectively, and first stepped holes 25 are provided on the four sides of the bottom surface of the support ring 23 and the four sides of the top surface of the pressure ring 24, and the upper and lower first stepped holes 25 are connected by connecting bolts 26; through holes 27 are provided at the four corners of the top surfaces of the support ring 23 and the pressure ring 24, and each screening hole 22 is arranged in an inclined manner, and the inner diameter of each screening hole 22 is the same;

[0032] The support ring 23 and the pressure ring 24 in the screening assembly 2 can not only clamp the wear-resistant rubber sheet 21, but also can stably clamp and fix the wear-resistant rubber sheet 21 through the multiple first step holes 25 and the multiple connecting bolts 26, thereby improving the stability of the use of the wear-resistant rubber sheet 21. Since the top surface of the wear-resistant rubber sheet 21 is provided with multiple screening holes 22, and the multiple screening holes 22 are distributed in a rectangular array, and each screening hole 22 is arranged in an inclined manner, and the inner diameter of each screening hole 22 is the same, the wear-resistant rubber sheet 21 and the screening hole 22 can not only screen the ore, but also reduce the ore on the screen.

At the same time, due to the good resilience of the wear-resistant rubber plate 21, the rebound force of the material can be increased, scale can be avoided, and the screening efficiency can be improved. The wear-resistant rubber plate 21 is flexible, and the probability of ore being stuck in the screening hole 22 is extremely small. Under the same screening hole rate conditions, the yield of the screening hole 22 is more than 1.3 times that of the steel mesh, and the service life is long, which is generally 15 to 20 times that of ordinary steel screens. At the same time, due to the design of the screening hole 22 with an inclination, when the maximum size of the ore passes through the constraint part of the screening hole 22, it will automatically slide down, thereby realizing the process of 0 hole blockage.

[0033] See also Figure 4 The top view shape of the wear-resistant rubber plate 21 is the same as the top view shape and size of the support ring 23 and the pressure ring 24, which can facilitate the support ring 23 and the pressure ring 24 to clamp and fix the wear-resistant rubber plate 21 stably and firmly.

[0035] Through the limiting ring 41 in the limiting assembly 4, it can provide space for opening the second step hole 42, and can also be fixed to the top surface of the support ring 3 through the second step hole 42 and the positioning screw 43, so as to achieve the purpose of limiting and fixing the screening assembly 2, thereby improving the stability of the use of the screening assembly 2, and then the second step hole 42 can be sealed by the rubber plug 44, thereby reducing the damage of the positioning screw 43 by the ore and increasing the service life of the positioning screw 43.

[0036] See also Figure 3-Figure 5The top view shape of the limiting ring 41 is the same as the top view shape of the pressing ring 24, and the outer diameter of the limiting ring 41 is the same as the inner diameter of the positioning frame 1, which can improve the stability of the limiting ring 41 pressing the pressing ring 24 and the firmness of the installation of the limiting ring 41.

[0037] During operation, the positioning frame 1 can be fixed on the vibration equipment and the support ring 3 can be installed and fixed. Then, the support ring 3 can be used to stably support the screening component 2 and can cooperate with the limiting component 4 to install and fix the screening component 2, thereby improving the stability of the use of the screening component 2. Then, the screening component 2 can be used to screen and filter the ore and reduce the wear of the ore on it.

The noise during the screening process can be reduced, and its wear resistance can be improved, thereby increasing its service life. At the same time, due to the good resilience of the wear-resistant rubber plate 21, the rebound force of the material can be increased, scale can be avoided, and the screening efficiency can be improved. The wear-resistant rubber plate 21 is flexible, and the probability of ore being stuck in the screening hole 22 is extremely small. Under the same screening hole rate conditions, the yield of the screening hole 22 is more than 1.3 times that of the steel mesh, and the service life is long, which is generally 15 to 20 times that of ordinary steel screens. At the same time, due to the design of the screening hole 22 with an inclination, when the maximum size of the ore passes through the constraint part of the screening hole 22, it will automatically slide down, thereby realizing the process of 0 hole blockage.

[0039] Through the limiting ring 41 in the limiting assembly 4, it can provide space for opening the second step hole 42, and can also be fixed to the top surface of the support ring 3 through the second step hole 42 and the positioning screw 43, so as to achieve the purpose of limiting and fixing the screening assembly 2, thereby improving the stability of the use of the screening assembly 2, and then the second step hole 42 can be sealed by the rubber plug 44, thereby reducing the damage of the positioning screw 43 by the ore and increasing the service life of the positioning screw 43.
