Description

Technical Field

[0002] Vibrating screen is a kind of mechanical equipment that uses the principle of mechanical vibration to screen, grade, dehydrate, remove impurities and other processing of materials. It is widely used in mining, coal, metallurgy, building materials, chemical industry, food, medicine and other industries. Its basic working principle is to generate periodic reciprocating vibration through the excitation device, causing the material on the screen surface to continuously jump, roll or slide, so that the material that meets the particle size requirements passes through the screen holes, and the material that does not meet the requirements remains on the screen surface, realizing the separation of materials.

[0003] Nowadays, when vibrating screens are used, they mainly meet their screening requirements through screens. However, the screens on traditional vibrating screens are mostly fixed. Once the angle of the fixed screen is determined, it is difficult to make large or frequent adjustments. When the characteristics of the processed materials and the screening requirements change, it is impossible to optimize the screening effect by simply adjusting the screen angle to adapt to the new working conditions, which may cause excess or insufficient processing capacity, affect production efficiency, and thus reduce the practicality of the vibrating screen.

The base 1 is the basic supporting component of the entire equipment, which is usually made of heavy steel and has sufficient strength and stability to bear the overall weight and vibration load of the screen machine. The elastic support member 2 is used to absorb and alleviate the vibration generated when the screen machine is working, and prevent the vibration from being directly transmitted to The foundation or adjacent equipment, while ensuring the stable operation of the screen box under vibration, multiple groups of elastic support members 2 are evenly distributed, which is helpful to evenly disperse the vibration force and improve the service life of the equipment. The mounting frame 5 is fixedly installed on the frame body 4, and the front end of the screen 7 is installed on the mounting frame 5 through the first threaded column 9 and the mounting hole 12, which mainly plays a positioning role. The rear end of the screen 7 is installed on the mounting frame 5 through the limiting mounting groove 11 and the second threaded column 8. The setting of the limiting mounting groove 11 enables the rear end of the screen 7 to be moved through the positioning of the second threaded column 8 and the limiting of the first threaded column 9 after installation, thereby changing the inclination angle of the screen 7, making the angle adjustment process of the screen 7 simple and quick, without the need to disassemble a large number of parts, greatly improving the operability of the equipment, and when the screen 7 is installed, it can be fastened to the mounting frame 5 by the fixing nut 10.

A discharge port is provided on the collecting tray 3. The collecting tray 3 is fixedly provided on the base 1, and is located directly below the screen 7. The collecting tray 3 is used to collect the material that falls after being screened by the screen 7. The collecting tray 3 is usually provided with a discharge port to facilitate the smooth discharge of the screened material to enter the subsequent processing link or storage and transportation equipment.

[0026] like Figure 1 As shown, a vibrator 6 is fixedly provided on the mounting frame 5. The vibrator 6 is fixed on the mounting frame 5 and is a power source for generating vibration. The vibrator 6 drives the mounting frame 5 and the screen 7 to vibrate periodically through its own vibration, thereby causing the material to jump and roll on the screen 7 to realize the screening process.

[0027] like Figure 8 As shown, multiple groups of fixing parts 13 are arranged on the frame 4, and a retractable electric support column 14 is arranged on the fixing part 13. The output end of the retractable electric support column 14 is movably installed with a plate body 16 through a first connecting part 15 and a spring connecting part 17. When the user needs to adjust the angle of the screen 7 on the vibrating screen, the retractable electric support column 14 on the fixing part 13 is started, and its output end drives the plate body 16 to move, so that the top of the plate body 16 can contact the bottom of the screen 7, providing support and auxiliary adjustment for the screen 7, so that the screen 7 can be faster and more accurate when adjusting the angle. The setting of the first connecting part 15 enables the plate body 16 to adjust its support angle so that it can contact more closely with the bottom of the screen 7. The setting of the two groups of spring connecting parts 17 enables the plate body 16 to return to its original position as the spring connecting part 17 pulls when the support stops.

[0028] Working principle: The base 1 is the basic supporting component of the entire equipment, which is usually made of heavy steel and has sufficient strength and stability to bear the overall weight and vibration load of the screen machine. The elastic support 2 is used to absorb and alleviate the vibration generated when the screen machine is working, prevent the vibration from being directly transmitted to the foundation or adjacent equipment, and ensure the stable operation of the screen box under vibration. Multiple groups of elastic support members 2 are evenly distributed, which helps to evenly disperse the vibration force and improve the service life of the equipment. The mounting frame 5 is fixedly installed on the frame 4, and the front end of the screen 7 is installed on the mounting frame 5 through the first threaded column 9 and the mounting hole 12, which mainly plays a positioning role. The rear end of the screen 7 is installed on the mounting frame 5 through the limiting mounting groove 11 and the second threaded column 8. The setting of the limiting mounting groove 11 enables the rear end of the screen 7 to be moved through the positioning of the second threaded column 8 and the limiting of the first threaded column 9 after installation, thereby changing the inclination angle of the screen 7, making the angle adjustment process of the screen 7 simple and quick, without the need to disassemble a large number of parts, greatly improving the operability of the equipment, and when the screen 7 is installed, it can be fastened to the mounting frame by fixing the nut 10. The collecting tray 3 is fixed on the mounting frame 5 and is located directly below the screen 7. It is used to collect the materials that fall after being screened by the screen 7. The collecting tray 3 is usually provided with a discharge port to facilitate the smooth discharge of the screened materials and enter the subsequent processing links or storage and transportation equipment. The vibrator 6 is fixed on the mounting frame 5 and is the power source for generating vibration. The vibrator 6 drives the mounting frame 5 and the screen 7 to vibrate periodically through its own vibration, so as to cause the materials to jump and roll on the screen 7 to realize the screening process. When the user needs to adjust the angle of the screen 7 on the vibrating screen, the fixed The retractable electric support column 14 on the component 13 is started, and its output end drives the plate body 16 to move, so that the top of the plate body 16 can contact the bottom of the screen 7, providing support and auxiliary adjustment for the screen 7, so that the screen 7 can be adjusted more quickly and accurately when adjusting the angle. The setting of the first connecting member 15 enables the plate body 16 to adjust its supporting angle so that it can contact more closely with the bottom of the screen 7. The setting of the two sets of spring connecting members 17 enables the plate body 16 to return to its original position as the spring connecting member 17 pulls when the support stops.
