Description

Technical Field

[0001] The present application relates to the technical field of vibrating screens, and specifically relates to a vibrating screen spring mechanism that is convenient for replacement. Background Art

[0002] A vibrating screen works by using the reciprocating spiral vibration generated by the excitation of a vibrator. The upper rotating weight of the vibrator causes the screen surface to generate a planar gyratory vibration, while the lower rotating weight causes the screen surface to generate a conical gyratory vibration. The combined effect is to cause the screen surface to generate a compound spiral vibration. The vibrating screen is connected to the support components through a spring mechanism.

[0003] Patent No. CN214260932U discloses a double-spring mechanism for preventing a vibrating screen from resonating. In this double-spring mechanism for preventing a vibrating screen from resonating, the lower spring is installed between the lower sleeve and the lower pressing block, and the upper spring is installed on the upper sleeve and is located between the lower pressing block and the upper pressing block. Through the lower limit of the lower pressing block and the upper limit of the upper pressing block, it is convenient to install, has a low cost, a wide range of applications, avoids the harm caused by the resonance of the vibrating screen, and reduces the operating noise of the equipment. However, the connection method of this spring mechanism with the vibrating screen and the bottom support components is welding. When some parts of the spring mechanism are damaged, it cannot be directly replaced, resulting in an increase in the time and cost required for the maintenance of the vibrating screen, affecting the service life of the vibrating screen, and having a relatively low cost performance.
