AI Technical Summary
During the crushing process, existing concrete crushers are prone to concrete blocks not being completely broken, which requires manual selection and re-brokenness, which is time-consuming and labor-intensive.
A concrete block crusher is designed, including a structure such as the feed hopper, support legs, annular plate, annular storage tank, storage box and motor. The filter bucket is driven to rotate through the motor. The broken concrete blocks are filtered through the filter bucket. Large pieces that are not completely broken are poured into the feed hopper for re-broken, avoiding manual selection.
The complete crushing of concrete blocks can be achieved without manual selection, which improves the crushing efficiency and reduces the time and labor of manual operation.
