[0002] Currently, in the mining industry, the GDZS1836 vibrating screen is a type of ore screening equipment. The GDZS1836 vibrating screen has a large dustproof enclosure. Its advantages include screening operations within the sealed dustproof enclosure, preventing dust leakage and creating a superior working environment. However, its disadvantages include difficulty in detecting potential malfunctions within the sealed dustproof enclosure during routine inspections; the accumulation of ore slime at the damping springs, accelerating spring wear; and the potential for ore jamming at the damping springs, leading to sudden spring breakage. These problems severely affect the normal operation of the vibrating screen. Therefore, to solve these problems, we propose a vibrating screen spring isolation protection device.

These problems seriously affect the normal operation of vibrating screens.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Preferably, the materials of the back dustproof shield and the dustproof isolation cover are wear-resistant, corrosion-resistant and have a certain degree of elasticity, such as metal or composite materials. The dustproof isolation cover is designed to include an adjustable fastening mechanism to adjust the installation tightness between the dustproof isolation cover and the vibrating screen protection box. The edges of the upper dustproof shield and the side dustproof shield are provided with sealing strips or sealing gaskets.

[0007] Preferred design: The dustproof isolation cover is equipped with an observation window.

[0016] EMBODIMENT

[0017] According to Figure 1, and Figure 2 As shown in the drawings, the technical scheme in the embodiment of the application effectively solves the technical problem that the fault hidden danger of the vibrating screen in the dustproof box is difficult to find during the inspection and patrol of the equipment, the ore slurry is easy to accumulate at the damping spring, the wear of the spring is aggravated, and the ore stuck at the damping spring will cause the spring to suddenly break, which seriously affects the normal operation of the vibrating screen, and the general idea is as follows:

[0018] In view of the problems in the prior art, the utility model provides a vibrating screen spring isolation protection device, including vibrating screen 4, vibrating screen 4 one side is provided with the protection box 5, vibrating screen 4 is fixedly installed with back dustproof ore baffle 1, dustproof isolation cover 2 is fixedly installed on the protection box 5, and the upper end of dustproof isolation cover 2 is provided with upper dustproof ore baffle 3, forms sealed cover, and upper dustproof ore baffle 3 covers the upper portion of back dustproof ore baffle 1, dustproof isolation cover 2 is provided with side dustproof ore baffle 7 on both sides, and side dustproof ore baffle 7 is close to back dustproof ore baffle 1, and dynamic contact is formed between the two, when vibrating screen 4 is vibrated and screened, the dynamic contact structure ensures that vibrating spring 6 and vibrating screen 4 screening space are in isolation state, and effectively prevent dust, mud and ore from entering vibrating spring 6 area.

[0019] The material of back dustproof ore baffle 1 and dustproof isolation cover 2 is selected from metal or composite material with wear resistance, corrosion resistance and certain elasticity, so as to enhance its durability and sealing performance, the design of dustproof isolation cover 2 includes adjustable fastening mechanism, which is used to adjust the installation tightness between dustproof isolation cover 2 and protection box 5, ensures the dustproof effect and facilitates disassembly and maintenance, the edge of upper dustproof ore baffle 3 and side dustproof ore baffle 7 is provided with sealing strip or sealing pad, so as to further enhance the sealing performance between dustproof isolation cover 2 and back dustproof ore baffle 1.

[0020] The observation window is arranged on dustproof isolation cover 2, which is convenient for observing the working state of damping spring without disassembling dustproof isolation cover 2, and potential faults can be found in time, the design of dustproof isolation cover 2 considers the vibration characteristics of vibrating screen 4, through optimizing structure design and material selection, it is ensured that it remains stable in the vibration environment, and does not affect the normal work of vibrating screen 4.

[0021] Working principle:

[0022] The working principle of the vibration screen spring isolation protection device of the present application mainly depends on the dynamic contact design between the back dustproof mine blocking skin 1 and the dustproof isolation cover 2. When the vibration screen 4 is working normally, due to the continuous vibration of the screen body, the back dustproof mine blocking skin 1, as the first line of defense, is directly fixed on the screen frame and vibrates with the vibration of the screen body. The dustproof isolation cover 2 is stably installed on the protection box 5 outside the vibration screen 4, and the upper dustproof mine blocking skin 3 on the dustproof isolation cover 2 closely adheres to the back dustproof mine blocking skin 1 to form a preliminary sealing barrier. At the same time, the side dustproof mine blocking skin 7 on both sides of the dustproof isolation cover 2 also closely adheres to the back dustproof mine blocking skin 1, and the three are effectively isolated from the vibration screen 4 screening space and the vibration spring 6 area through dynamic contact. The key of this dynamic contact design is that it can adapt to the vibration characteristics of the vibration screen 4, which not only ensures the sealing effect, but also avoids the aggravation of wear caused by fixed connection. During the vibration process, the slight displacement and friction between the back dustproof mine blocking skin 1 and the dustproof isolation cover 2 actually play the role of self-cleaning and sealing enhancement, further improving the isolation protection effect. In addition, the material selection and structure design of the dustproof isolation cover 2 also fully consider the factors of wear resistance, corrosion resistance and elasticity, etc., to ensure its long-term stable operation in harsh working environment.

[0023] Secondly, the device not only effectively prevents dust, mud and impurities such as ore from entering the vibration spring 6 area, but also makes the originally hidden vibration spring 6 area easy to observe and maintain through its unique design structure. The observation window provided on the dustproof isolation cover 2 provides an intuitive inspection channel for the operator, and the working state of the vibration spring 6 can be observed without disassembling the dustproof isolation cover 2, so that potential fault hazards can be found in time. This design not only improves the fault troubleshooting efficiency, but also reduces the maintenance cost. When the vibration spring 6 is found to have wear or failure, the operator can quickly locate the problem and take appropriate maintenance measures. In addition, due to the adjustable fastening mechanism design between the dustproof isolation cover 2 and the protection box 5, the disassembly and installation process of the whole device becomes simple and fast, further improving the maintainability and flexibility of the equipment.

[0024] Finally, it should be pointed out that: obviously, the above examples are only examples for clearly illustrating the present application, and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation modes. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
