Description

Technical Field

[0001] This utility model relates to the field of vibrating screen fixing technology, and in particular to a multi-layer screen fixing mechanism for a mining vibrating screen. Background Technology

[0002] A mining vibrating screen is a widely used screening equipment in the mining industry. It mainly uses vibration to make the material move in a directional jumping motion on the screen surface, thereby achieving the separation of materials of different particle sizes. Mining vibrating screens are usually powered by a vibrating motor or other vibration source to make the screen box vibrate at high frequency. After the material enters the screen box from the feed inlet, under the action of vibration, particles smaller than the screen hole size pass through the screen and become undersize material, while particles larger than the screen hole size remain on the screen surface and continue to move forward, eventually being discharged from the discharge outlet, thus achieving the screening and grading of materials.

[0003] Existing mining vibrating screens have some shortcomings in their fixing methods. Traditionally, most screens are fixed with bolts. Over time, the screens are prone to damage when screening ore, requiring disassembly and reassembly. Bolts are prone to oxidation and rust outdoors, making disassembly difficult and increasing the burden on workers, which is time-consuming and labor-intensive. To address these issues, a multi-layer screen fixing mechanism for mining vibrating screens has been proposed for improvement and upgrading. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer screen fixing mechanism for a mining vibrating screen to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a multi-layer screen fixing mechanism for a mining vibrating screen, including a mounting frame, a vibrating screen frame fixedly mounted on the upper end of the mounting frame, a first screen and a second screen respectively mounted inside the vibrating screen frame, T-shaped sliders fixedly mounted on both sides of the outer walls of the first screen and the second screen, each T-shaped slider being slidably connected to a guide slide plate, both sets of guide slide plates being fixedly mounted on both sides inside the vibrating screen frame, each set of guide slide plates being fixedly connected to a mounting frame at one end, and each set of guide slide plates being provided with a limit structure at the other end;

[0006] The mounting frame has a fixing structure inside, which includes mounting plates. There are three mounting plates in total, and all three mounting plates are fixedly installed on the inner wall of the mounting frame. The mounting plates are rotatably connected to a first limiting clamp and a second limiting clamp. The outer sides of the first limiting clamp and the second limiting clamp are provided with buffer springs. Three limiting rods are fixedly installed on the outer wall of one end of the first screen and the second screen. The diameter of the limiting rods is adapted to the size of the first limiting clamp and the second limiting clamp.

[0007] As a preferred embodiment of the above technical solution, a fixing rod is fixedly installed inside the mounting plate, two limiting protrusions are fixedly provided on the outer wall of the first limiting clamp, and one limiting protrusion is fixedly provided on the outer wall of the second limiting clamp, with the limiting protrusion intersecting with the other two limiting protrusions.

[0008] As a preferred embodiment of the above technical solution, all three limiting protrusions are rotatably mounted on the fixed rod, and the outer walls of the first and second limiting clamps are fixedly connected to a fixing block, with the bottom of the fixing block connected to one end of the buffer spring, and the other end of the buffer spring fixedly mounted on the outer wall of the mounting plate.

[0009] As a preferred embodiment of the above technical solution, the limiting structure includes a positioning seat fixedly installed on one end of the guide slide plate, a limiting plate slidably connected inside the positioning seat, and limiting blocks provided on the outer wall of the limiting plate, with the limiting blocks slidably connected inside the positioning seat.

[0010] As a preferred embodiment of the above technical solution, the outer wall of the limiting plate is symmetrically threaded with two threaded rods, one end of which is fixedly connected to a threaded knob, and the other end of which is connected to the outer wall of the positioning seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The device of this utility model is equipped with components such as a T-shaped slider, a guide slide, a mounting plate, a first limiting clamp, a second limiting clamp, and a buffer spring. When the two screens slide into the interior along the guide slide via the T-shaped slider, the limiting rod on one end of the screen presses against the first and second limiting clamps. Under the elastic force of the buffer spring, the limiting rod is pre-tightened and fixed. At the same time, when the screen is damaged after long-term use, the principle is the same as above, and the screen can be directly pulled out for replacement, avoiding the problems of disassembly difficulties caused by bolt fixing, saving time and effort.

[0013] 2. The device of this utility model is equipped with components such as a positioning seat, a limiting plate, a threaded knob, and a threaded rod. After the screen is fixed, the limiting plate slides along the positioning seat to limit the bottom of the screen. Finally, the threaded knob is rotated to drive the threaded rod to rotate and limit the limiting plate. This facilitates the double-fixed installation of the screen and improves the screening stability of the screen.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the figure, this embodiment provides a multi-layer screen fixing mechanism for a mining vibrating screen, including a mounting frame 1. A vibrating screen frame 3 is fixedly installed on the upper end of the mounting frame 1. A first screen 2 and a second screen 4 are respectively installed inside the vibrating screen frame 3. T-shaped sliders 61 are fixedly installed on both sides of the outer wall of the first screen 2 and the second screen 4. Guide slide plates 6 are slidably connected to the T-shaped sliders 61. The two sets of guide slide plates 6 are fixedly installed on both sides inside the vibrating screen frame 3. A mounting frame 7 is fixedly connected to one end of the two sets of guide slide plates 6, and a limit structure 5 is provided at the other end of the two sets of guide slide plates 6.

[0024] The mounting frame 7 has a fixing structure 8 inside, which includes mounting plates 81. There are three mounting plates 81, and all three mounting plates 81 are fixedly installed on the inner wall of the mounting frame 7. The mounting plates 81 are rotatably connected to the first limiting clamp 83 and the second limiting clamp 84 respectively. The outer side of the first limiting clamp 83 and the second limiting clamp 84 is provided with a buffer spring 87. Three limiting rods 21 are fixedly installed on the outer wall of one end of the first screen 2 and the second screen 4. The diameter of the limiting rods 21 is adapted to the size of the first limiting clamp 83 and the second limiting clamp 84.

[0025] like Figures 3 to 4 As shown, a fixing rod 82 is fixedly installed inside the mounting plate 81. Two limiting protrusions 85 are fixedly provided on the outer wall of the first limiting clamp 83, and one limiting protrusion 85 is fixedly provided on the outer wall of the second limiting clamp 84. The limiting protrusion 85 is interlocked with the other two limiting protrusions 85. All three limiting protrusions 85 are rotatably mounted on the fixing rod 82. Fixing blocks 86 are fixedly connected to the outer walls of the first limiting clamp 83 and the second limiting clamp 84. The bottom of the fixing block 86 is connected to one end of the buffer spring 87. The other end of the buffer spring 87 is fixedly installed on the outer wall of the mounting plate 81.

[0026] By staggering the limiting protrusions 85 on the outer wall of the second limiting clamp 84 and the two limiting protrusions 85 on the outer wall of the first limiting clamp 83, the first limiting clamp 83 and the second limiting clamp 84 are positioned relative to each other when they rotate along the fixed rod 82. The limiting rod 21 is compatible with the diameter of the first limiting clamp 83 and the second limiting clamp 84, and the two buffer springs 87 are symmetrically positioned.

[0027] like Figure 5 As shown, the limiting structure 5 includes a positioning seat 51 fixedly installed on one end of the guide slide plate 6. A limiting plate 52 is slidably connected inside the positioning seat 51. Limiting blocks 53 are provided on the outer wall of the limiting plate 52 and are slidably connected inside the positioning seat 51. Two threaded rods 55 are symmetrically threaded on the outer wall of the limiting plate 52, and a threaded knob 54 is fixedly connected to one end of the threaded rod 55. The other end of the threaded rod 55 is connected to the outer wall of the positioning seat 51.

[0028] By sliding the limiting plate 52 along the positioning seat 51 so that one end of it fits against the bottom of the screen, it is easy to limit and fix the screen, avoiding problems such as the screen slipping due to loosening during screening. The limiting plate 52 is positioned and pre-tightened by two sets of threaded rods 55.

[0029] The working principle and process of this utility model are as follows: First, the operator slides the first screen 2 and the second screen 4 inside the two sets of guide slide plates 6 using the T-shaped sliders 61 on both sides. At the same time, when pushing the screen, the three limiting rods 21 on one end of the screen press against the first limiting clamp 83 and the second limiting clamp 84 on the mounting plate 81. This causes the pushing force of the limiting rods 21 to press the limiting protrusions 85 on the first limiting clamp 83 and the second limiting clamp 84 to rotate along the fixed rod 82. Due to the pressure, the first limiting clamp 83 and the second limiting clamp 84 rotate. The force of the relative expansion causes the fixing block 86 to compress the buffer spring 87. When the limiting rod 21 is fully compressed between the two limiting clamps, the buffer spring 87 resets the limiting clamps under the elastic force to pre-tighten and limit the limiting rod 21, which facilitates stable fixing of the screen and easy disassembly and replacement. At the same time, the limiting plate 52 supports and limits the bottom of the screen by sliding the limiting block 53 in the positioning seat 51. Finally, by rotating the two threaded knobs 54, the threaded rod 55 is driven to tighten the limiting plate 52, which facilitates the double fixing installation of the screen.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
