PURPOSE: To provide an automatic hammering system for improving cleaning efficiency by applying automatic impact to filter housings when backwashing is performed, easily separating foreign materials stuck to filters by vibrating the filters, and reducing leakage possibility due to abrasion by inducing increase of stable flow ultimately. CONSTITUTION: The automatic hammering system is characterized in that a ball valve (1) for filtering flow and a ball valve (2) for backwashing flow are positioned in an upper part of filter housings (7), a ball valve (11) for filtering flow and a ball valve (12) for backwashing flow are positioned in a lower part of the filter housings, automatic hammering is consisted of air knockers (3), timers (6) and solenoid valves (5), clamps (4) welded to the air knockers to give vibration to the filter housings, and a control panel (10) closes the ball valves (1,11), opens the ball valves (2,12) and operates the solenoid valves at the same time when a backwashing signal is generated by sensing a designated pressure so that impact is applied to the filter housings by the air knockers to send the separated foreign materials to a disuse tank through a backwash discharge port by separating foreign materials stuck to the outer surface of filters (8) by backwashing flow.
