PURPOSE: An apparatus for automatically removing tar on a scraper is provided to prevent tar from being adhered onto the backside of the scraper of the lower part of a coke oven chamber, and prevent gas leakage due to cohesion defects of doors. CONSTITUTION: The apparatus for automatically removing tar on a scraper comprises a guide rail(19) which is installed by being connected to the lower part of a base(22) of a jump cleaner of a pusher car; guide beams which are installed so that they are moved along the guide rail(19); a cylinder moving back and forth(17) which is fixed to the base(22) so as to operate the guide beams; disk gears(10a,10b) which are rotationally fixed to the front of upper guide beams(21a,21b) in the guide beams; an upper plate(7) which is perpendicularly installed to a length direction of the upper guide beams(21a,21b) so that the upper guide beams(21a,21b) are stationed; horizontal gears(11a,11b) which are rotationally fixed to the upper plate(7) by a hinge, and on the opposite surfaces of which toothed wheels being in gear with the disk gears(10a,10b) are formed; fixed rollers(12a,12b) and touch rollers which are installed at both ends of the operation shaft(8) so that the fixed rollers(12a,12b) and touch rollers are rolled around an operation shaft(8) fixed to the horizontal gears(11a,11b) and the upper plate(7); and touch parts which are fixed to the rear of the upper guide beams(21a,21b) so that the touch parts contact the touch rollers.
