Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen for preventing material jumping. Background Technology

[0002] Vibrating screens are widely used mechanical devices in industrial production for material screening and grading. Their core function lies in utilizing vibration technology to generate vibrations at specific frequencies within the screen, thereby achieving precise separation of materials with different particle sizes. This equipment is used in industrial applications of all sizes, from small laboratories to large factory production lines.

[0003] Existing vibrating screens are prone to material jumping during the screening process, requiring manual picking up of the jumping material. This not only increases the number of steps for workers but also leads to low screening efficiency. Therefore, a vibrating screen with anti-jumping technology is proposed. Utility Model Content

[0016] 1. This anti-slip vibrating screen, through the setting of the adjustment mechanism, when in use, connect the power supply and start the electric push rods on both sides of the vibrating chamber. The electric push rods extend and retract, driving the baffles on the extension blocks connected at the ends to adjust the height.
