A Rotary Dust Removal Device Capable of Self Removing Caught Dust

摘要

The present invention relates to a rotary dust remover capable of autonomously removing caught foreign materials. More specifically, an operation load of an operation unit to operate a rake is measured, so the rake is reversely rotated to remove foreign materials caught in a main screen when overload equal to or larger than a predetermined reference occurs. Therefore, the rake or the operation unit is prevented from being damaged or failed, and the foreign materials caught in the main screen can be removed without individual work. Moreover, the foreign materials caught in the main screen are easily removed through a gap maintenance member inserted to be able to rotate and a withdrawal side support unit rounded and sunk inside, and an opening/closing screen can be opened in reverse rotation of the rake, so the foreign materials caught by the reverse rotation of the rake can be smoothly removed.
