How Does Screening Bucket Work? | Screening Bucket Work Principle
The screening bucket is driven by dual-vibration motors. When the
two vibration motors are rotated synchronously and in reverse, the
exciting force generated by the eccentric blocks cancels each other
in the direction parallel to the axis of the motor and superimposes
a resultant force in the direction perpendicular to the axis of the
motor, so the motion trajectory of the screen machine for a
straight line. The two motor shafts have an inclination angle
relative to the screen surface. Under the combined force of the
exciting force and the self-gravity of the material, the material
is thrown up on the screen surface and moves forward in a straight
line, so as to achieve the purpose of screening and grading the
material.
Screening Bucket Features
- Our excavator sieve bucket is not easy to block, the operation is
stable, the noise is low, the structure is simple, and the
maintenance is convenient.
- The screening drum can be rotated forward and reverse, which is
easy to screen.
- The product realizes the material screening work through the
rotation of the drum,
- The high-torque low-speed hydraulic motor is highly sealed and can
work underwater.
- Adopting a two-speed design, the high and low speeds can be
switched arbitrarily as needed.
- Respond to different needs by replacing sieve plates with different
apertures,
- The whole machine adopts high-performance steel plate mortise and
tenon joint welding, which is more firm, not easy to open welding
and cracking, high strength, and maintenance-free.
- Weighing support shafts and bearings extend the maintenance period,
saving costs and increasing profits.
