Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an adjustable high-frequency vibrating screen. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

[0003] According to a multi-stage adjustable vibrating screen disclosed in China Utility Model Publication No. CN114570635A, an adjusting steel plate is provided on the surface of the vibrating screen body, and the position of the cylinder piston rod in the adjusting groove is adjusted and fixed in advance, so that the vibration amplitude can be limited to a certain extent during internal operation, thereby solving the problem that the vibration amplitude of the traditional vibrating screen structure cannot be adjusted and cannot adapt to the needs under different circumstances. Through the multi-stage adjustable mechanism, the height position of the fork frame and the running frame can be adjusted by swinging, and the height gap between the bottom running frame and the supporting plate can be adjusted, and the anti-twisting steel frame provided on the surface of the supporting plate can prevent the bottom from cracking when the device vibrates, thereby solving the problem that the existing vibrating screen is set as an integral device, and different types of vibrating screens need to be used for screening when screening different materials, which is inconvenient. The current vibrating screen structure is a forced direct vibration transmission vibration force mode, and the box body is chaotically excited, and long-term vibration will cause cracking.

[0004] However, although the device can adjust the vibration amplitude of the vibrating screen, the stability of the device is affected to a certain extent by the existence of the adjustment structure. After the vibrating screen is used for a long time, problems are likely to occur. Utility Model Content
