Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a vibrating screen for mining, which is convenient for screen replacement. Background Art

[0002] In the mining industry, a vibrating screen is a key device used to separate different particle sizes in ores to improve the quality and output of ores. However, there are many challenges in screen replacement of traditional vibrating screens, such as complex and time-consuming operation, and the problem of possible production downtime. Screen replacement of traditional vibrating screens usually requires a long downtime and the intervention of professional technicians. This not only increases the maintenance cost, but also may affect the production efficiency and the continuity of the production line.

[0003] Screen replacement usually involves multiple steps, such as unclamping the screen fixture, removing the old screen, installing the new screen and refixing it, etc. These steps require a high level of operation skills and time costs. Since screen replacement involves the shutdown of the equipment, this may lead to the stagnation of the production line and the reduction of production capacity, especially in the case of high output and continuous production, the impact is particularly significant. Summary of the Utility Model

[0004] In order to overcome the disadvantages of troublesome operation and time-consuming when replacing the screen, which affect the production efficiency, the purpose of the utility model is to provide a vibrating screen for mining, which is simple and convenient for screen replacement.

[0005] A vibrating screen for mining, which is convenient for screen replacement, includes a support frame, shock absorbers, vibration motors, a vibration frame, a guide frame, hinged clamping plates, a screen, bolts, a disassembly mechanism and a pulling mechanism. Four shock absorbers are fixedly connected to the middle of the support frame, a vibration frame is fixedly connected to the top of the support frame, vibration motors are installed at the bottom of the vibration frame, at least two pairs of guide frames are fixedly connected to the front and rear sides inside the vibration frame, a hinged clamping plate is slidably connected between the front and rear corresponding guide frames, a screen is installed in the hinged clamping plate through bolts, a disassembly mechanism for clamping the hinged clamping plate is connected to the right side of the vibration frame, a pulling mechanism for cooperating with the disassembly mechanism is connected to the right side of the vibration frame, and the number of the disassembly mechanism and the pulling mechanism is at least two.

[0006] As a further preferred solution, the disassembly mechanism includes guide frames, sliding rods, wedge blocks and elastic members.

[0008] As a further preferred solution, clamping grooves are formed on the sides of the hinged clamping plates close to each other.

[0009] As a further preferred solution, the rear sides of each pair of guide frames are connected to each other.

Detailed Embodiment

[0018] The technical solutions of the present utility model will be further described below with reference to the drawings.

[0019] A vibrating screen for mining that facilitates the replacement of the sieve, as Figures 1-5As shown in the figure, it includes a support frame 1, shock absorbers 2, vibration motors 3, vibration frames 4, guide frames 5, hinged splints 6, screen meshes 7, bolts 8, a disassembly mechanism and a pulling mechanism. Four shock absorbers 2 are fixedly connected to the middle of the support frame 1. The shock absorbers 2 can effectively reduce the noise and vibration generated during the operation of this vibrating screen, protect the equipment and improve the work efficiency at the same time. The vibration frame 4 is fixedly connected to the top of the support frame 1. The vibration motor 3 is installed at the bottom of the vibration frame 4. Two pairs of guide frames 5 are fixedly connected to the front and rear sides inside the vibration frame 4. A hinged splint 6 is slidably connected between the front and rear corresponding guide frames 5. The screen meshes 7 are installed in the hinged splints 6 through bolts 8. When screening ores, the vibration frame 4 is driven to vibrate by the vibration motor 3, and the ores are placed on the topmost screen mesh 7 for screening. A disassembly mechanism for clamping the hinged splint 6 is connected to the right side of the vibration frame 4, and a pulling mechanism for cooperating with the disassembly mechanism is connected to the right side of the vibration frame 4. The numbers of the disassembly mechanism and the pulling mechanism are the same as the number of the screen meshes 7, and one screen mesh is correspondingly equipped with a disassembly mechanism and a pulling mechanism.

[0020] When the screen mesh 7 needs to be replaced, through the cooperation of the pulling mechanism and the disassembly mechanism, the disassembly mechanism no longer clamps the hinged splint 6, the hinged splint 6 is pulled outwards from the guide frame 5, the hinged splint 6 is opened, the bolt 8 is taken out and then the screen mesh 7 is removed. The new screen mesh 7 is placed into the hinged splint 6, and the new screen mesh 7 is installed in the hinged splint 6 through the bolt 8, and then the hinged splint 6 is reset. The operation is simple and convenient, and the screen mesh 7 can be quickly replaced without affecting the production efficiency.

[0021] As Figure 1 , Figure 4 and Figure 5 As shown in the figure, the disassembly mechanism includes guide frames 9, sliding rods 91, wedge blocks 10 and elastic members 11. Guide frames 9 are fixedly connected to the right sides of the front and rear ends of the vibration frame 4. Sliding rods 91 are slidably connected to the middle of the guide frames 9. Wedge blocks 10 are fixedly connected to the ends of the sliding rods 91 close to each other. Elastic members 11 are fixedly connected between the wedge blocks 10 and the guide frames 9. The elastic members 11 are arranged as helical springs. Initially, the elastic members 11 are in their original states, and the wedge blocks 10 are in contact with the hinged splints 6, so that the hinged splints 6 will not slide out of the guide frames 5 when screening ores. The disassembly mechanism can fix the hinged splints 6 through the wedge blocks 10 and can also move the wedge blocks 10 to facilitate the removal of the hinged splints 6.

[0022] When the screen mesh 7 needs to be replaced, the front and rear sliding rods 91 are slid away from each other on the guide frame 9 through the pulling mechanism, so that the wedge block 10 moves away from the articulated clamping plate 6, and the elastic member 11 is compressed. Then, the articulated clamping plate 6 is taken out to replace the screen mesh 7. When the articulated clamping plate 6 needs to be reset, align the articulated clamping plate 6 with the middle of the guide frame 5, and squeeze the wedge block 10 with the articulated clamping plate 6, so that the front and rear wedge blocks 10 move away from each other, and the front and rear sliding rods 91 slide away from each other. The elastic member 11 is compressed. After the articulated clamping plate 6 slides and resets in the guide frame 5, the articulated clamping plate 6 no longer squeezes the wedge block 10, and the elastic member 11 returns to its original state, causing the wedge block 10 and the sliding rod 91 to automatically reset.

[0023] As Figure 1 , Figure 4 and Figure 5 shown, the pulling mechanism includes a wedge plate 12, a guide tube 13 and a pull rod 14. Guide tubes 13 are fixedly connected to the right sides of the front and rear ends of the vibrating frame 4. Pull rods 14 are slidably connected to the right sides of the front and rear ends of the vibrating frame 4 through the guide tubes 13. Wedge plates 12 are fixedly connected to the ends of the pull rods 14 close to the guide frame 9. Through the cooperation of the pulling mechanism and the disassembly mechanism, the disassembly mechanism is disengaged from the locking of the articulated clamping plate 6, facilitating the removal of the articulated clamping plate 6 for the replacement of the screen mesh 7. This process simplifies the replacement steps of the screen mesh 7, reduces the downtime, and improves the production efficiency. Initially, the inclined surface of the wedge plate 12 contacts the sliding rod 91. During the cooperation of the pulling mechanism and the disassembly mechanism, pull the pull rod 14 away from the vibrating frame 4. The movement of the pull rod 14 causes the wedge plate 12 to squeeze the sliding rod 91, making the front and rear sliding rods 91 slide away from each other, and the elastic member 11 is compressed. After the articulated clamping plate 6 is reset, release the pull rod 14, and the elastic member 11 returns to its original state, causing the sliding rod 91 to drive the wedge plate 12 to reset, thereby resetting the pull rod 14, facilitating the replacement of the screen mesh 7 next time.

[0024] As Figure 3 shown, clamping grooves 51 adapted to the edges of the screen mesh are provided on the sides of the articulated clamping plate 6 where the clamping plates are close to each other. When the new screen mesh 7 is placed into the articulated clamping plate 6, the edges of the new screen mesh 7 are clamped to the articulated clamping plate 6 through the clamping grooves 51, and then the new screen mesh 7 is fixed to the articulated clamping plate 6 through the bolts 8. The clamping grooves 51 can limit the position of the screen mesh 7, simplifying the installation and fixation of the screen mesh 7.

[0025] As Figure 2 shown, the rear sides of each pair of guide frames 5 are closed. During the screening operation, the guide frame 5 and the wedge block 10 can fix the articulated clamping plate 6, preventing the articulated clamping plate 6 from shifting due to the vibration of the vibrating frame 4, keeping the screen mesh 7 in the correct position, and ensuring the normal operation of the screen mesh 7.

[0026] As Figure 1 and Figure 4As shown, the mesh number of the upper screen 7 is less than that of the lower screen 7. After the upper screen 7 screens the ore, the ore falls from the upper screen 7 to the lower screen 7, thereby achieving graded screening of the ore and improving processing efficiency and product quality.

[0027] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
