PROBLEM TO BE SOLVED: To automatically and continuously clean post cones by forming a shell case having void parts reaching the rear from the front of a main part, rotatably and obliquely arranging brush bodies on both sides of the void parts, and synchronously rotating the brush bodies by a drive source. SOLUTION: A shell case which is a box unit whose front and rear are obliquely formed is provided with void parts in the vertical direction and, in the bottom part thereof and to the upper surface thereof, a cover 2 is fitted, and close to the cover 2, stays 3 each having a through-hole are installed. In the void parts, large-diameter brush parts and small-diameter brush parts are alternately installed to form brush bodies 4-6 in parallel in the form of assembled cylinders. The brush bodies 4-6 are rotatably supported on a hydraulic motor 10 appropriately by support members. In this way, post cones can be continuously and efficiently cleaned without applying large pressure to the post cones. |
