AI Technical Summary
Technical Problem
When the existing coal leveler is leveling coal, the return spring is easily compressed under low load, causing the scraper plate to return to its original position and affecting the leveling effect.
Method used
A buffer mechanism, including hydraulic oil and a pressure sensor, is adopted to control the buffer compression by sensing the rated pressure to avoid hard collisions. The smooth movement of the scraper plate is achieved by the cooperation of hydraulic oil and return spring.
Benefits of technology
This method avoids hard collisions during the leveling process, improves the leveling effect, and ensures a smooth coal surface.
