AI Technical Summary
When weighing concrete, existing large weighbridges often leave concrete residue that hardens and becomes difficult to clean completely, affecting weighing accuracy.
The system uses a drive motor and a transmission belt to move the mounting frame, high-pressure nozzles spray high-pressure water to rinse, a servo motor drives the cleaning rollers to rotate and scrub, and a scraper pushes the wastewater out of the weighbridge body.
It effectively improves the cleaning effect of the weighbridge body and increases the weighing accuracy.
