Description

Technical Field

[0001] The utility model relates to the technical field of stacked screen machines, in particular to a stacked screen with a detachable driving beam. Background Art

[0002] At present, stacked screens are widely used in mineral grading and screening due to their large processing capacity and high screening efficiency. Stacked screens use two vibrators running in opposite directions to drive the screen frame to move in a straight line, so that the material on the screen box is continuously subjected to high-frequency and small-amplitude vibrations, and continuously jumps on the inclined screen box, so that the material is dispersed and the purpose of grading and screening is achieved.

[0003] However, during the long-term use of the stacked screens, problems such as vibration exciter failure and damage and unscheduled maintenance of the vibration exciter are prone to occur, so there is a situation where the vibration exciter is removed from the stacked screens.

[0004] Most of the common stacked screens on the market use welding or direct bolts to fix the vibrator and the driving beam on the vibrator to the transmission frame. When disassembling the vibrator, it is necessary to turn multiple bolts in sequence to disassemble the driving beam. The disassembly efficiency is low and the vibration generated during the operation of the vibrator can easily cause the bolts to loosen, thereby affecting the installation stability of the vibrator.
