AI Technical Summary
In existing technologies, solid concrete admixtures are prone to blockage when fed through pipes due to varying particle sizes and poor flowability, which affects weighing efficiency and progress, leading to inaccurate measurement and impacting the quality of concrete products.
The weighing assembly uses a first motor to drive the threaded rod to rotate, which in turn moves the pusher up and down. The second motor drives the protrusion on the round rod to vibrate the hose to prevent blockage. After weighing is completed, the cylinder pushes the placement plate to tilt for easy discharge.
This effectively avoids material blockage, improves the efficiency and accuracy of the weighing process, reduces downtime, ensures smooth material flow, and enhances the quality of concrete products.
