- the scraping unit 200 of the foreign matter removal apparatus 1 of the present invention includes a scrubbing member 216.
- the rod cleaner 213 of the removal device 1 one end is coupled to the portion of the support block member 215 adjacent to the through hole 215a, the other end is in the form of a trumpet contacting the rod member 211 It may include a scrubbing member 216 is provided.
- the road cleaner 213 may further include a scrub member 216.
- the other end portion of the scrub member 216 is provided as a free end that is not coupled to any configuration, and is configured to be provided on the outer surface of the rod member 211 that is reciprocally moved, and accordingly, the rod member ( 211) foreign matter such as a spatter attached to the other end of the scrubbing member 216, so that the spatter attached to the rod member 211 can be removed from the rod member 211. .
- the scrub member 216 is formed to correspond to the diameter of the rod member 211 so that only the other end is in contact with the outer surface of the rod member 211. It does not affect the reciprocating movement of the rod member 211, there is an advantage that can be removed by scraping only foreign matter such as spatter attached to the rod member 211.
