Description

Technical Field

[0001] This utility model relates to a vibrating screen, and more particularly to a square vibrating screen with quick screen replacement. Background Technology

[0002] Currently, there are significant limitations in the way square vibrating screens are fixed on the market. Most square vibrating screens use bolts to secure the screen. This method has revealed numerous problems in practical use, especially during screen replacement, where its drawbacks are particularly pronounced.

[0003] When a screen needs replacement due to wear, blockage, or damage from prolonged use, operators must use specialized tools to disassemble the bolts securing the screen one by one. Since screens are typically secured by multiple bolts, this process is not only time-consuming and labor-intensive, but also difficult to perform within the confined space of the equipment. According to actual operational data, replacing a screen can take several hours just to disassemble and install the bolts. Furthermore, frequent disassembly and installation of bolts can easily lead to stripped bolt threads and wear on the screen mounting holes, thus affecting the installation accuracy and stability of the screen.

[0004] Therefore, there is an urgent need to develop a square vibrating screen with quick screen replacement to solve the above-mentioned technical problems. Utility Model Content

[0026] Please refer to the following: Figures 1-10This invention provides a square vibrating screen with quick screen replacement. The square vibrating screen with quick screen replacement includes a support 1, a hopper 2, a hinge structure, a vibrating frame 7, a vibrating structure, a screen plate 10, and a fixing structure. The top of the support 1 has a downwardly recessed hopper 2, through which screened materials are discharged. The upper part of the support 1 is connected to the vibrating frame 7 via the hinge structure. A vibrating structure providing power for screening is installed on the support 1 below the vibrating frame 7. The vibrating structure provides power for screening the materials, which is transmitted to the vibrating frame 7 via the hinge structure. The vibrating frame 7 is installed with its left side higher than its right side, and has a discharge port on its right side. The bottom of the vibrating frame 7 is detachably connected to the screen plate 10 via a fixing structure. The fixing structure includes a left fixing structure 11 and a right fixing structure 12, which fix the screen plate 10 to the vibrating frame. The bottom of frame 7; the hinge structure includes a rotating sleeve 3, a connecting sleeve 4, a hinge rod 5, and a connecting shaft 6. Rotating sleeves 3 are symmetrically arranged on the upper front and rear sides of the support 1. The rotating sleeves 3 are rotatably connected to the support 1.

The output shaft of the motor 9 is connected to one end of the convex shaft 8. The protruding part of the convex shaft 8 is hinged to the vibration frame 7 through a connecting rod.

[0027] This embodiment provides a square vibrating screen with quick screen replacement. Compared with the prior art, when screening materials, the materials are placed in the vibrating frame 7. By controlling the motor 9 to rotate, the cam shaft 8 is driven to rotate, causing the vibrating frame 7 to vibrate. Materials smaller than the aperture of the screen plate 10 fall through the screen plate 10 and are discharged into the discharge hopper 2, while materials larger than the aperture of the screen plate 10 are discharged through the right side of the vibrating frame 7. When the screen plate 10 needs to be replaced, the left side of the screen plate 10 is first loosened through the left fixing structure 11, and then... The left side of the screen plate 10 rotates upward to detach from the vibration frame 7. The right side fixing structure 12 assists in popping out the loosened screen plate 10, which can then be removed. Through the cooperation of the left side fixing structure 11 and the right side fixing structure 12, both sides of the screen plate 10 can be fixed, allowing the screen plate 10 to perform screening work stably. When the screen plate 10 needs to be disassembled, simply loosen the left side fixing structure 11 to quickly remove the screen plate 10.

When installing the mesh plate 10, the elastic pad 124 is tightly attached to the mesh plate 10 to ensure the stability of the mesh plate 10 installation. At the same time, the mesh plate 10 also has a certain buffer space to protect the mesh plate 10. When the mesh plate 10 needs to be removed, after the left-side fixing structure 11 is released, the spring II 123 is reset, which helps to push the mesh plate 10 out for removal and reduces the difficulty of removal.

[0032] In a preferred embodiment, it can be adopted Figure 5 The structure shown also includes a pad 71. A pad 71 is provided on the vibration frame 7 below the left wall of the mesh plate 10 to support the left side of the mesh plate 10, facilitate the replacement of the mesh plate 10, and share the weight borne by the mesh plate 10, thereby improving the service life of the equipment.
