AI Technical Summary

Technical Problem

Existing sand and gravel feeding devices are prone to clogging in water-containing sand and gravel mixtures and cannot effectively screen and remove impurities, resulting in low feeding efficiency and poor product quality.

Method used

A precise metering and feeding device for sand and gravel was designed, comprising a feeding hopper, a pushing component, a filter plate, and a motor. Through the screening by the filter plate, the rotation number and speed of the rotating shaft controlled by the motor, and the stable pushing by the pushing component, the device achieves precise metering and double screening of sand and gravel, removes large particle impurities, and ensures product purity.

Benefits of technology

It achieves precise control of sand and gravel feeding, reduces feeding errors and product quality fluctuations, improves feeding efficiency and product purity, and extends equipment service life.
