The present invention relates to a brush device for exfoliating rocket propulsion fuel that can adjust the length of brushes or can replace the brushes when the brushes are abraded in the process of exfoliating rocket propulsion fuel, and can be manufactured simply owing to the simple configuration of a fixing means as the fixing means is arranged to fix the brushes, which are stuck into the outer circumference of a rotating body part at multiple stages, by pressing the brushes simultaneously. The brush device for exfoliating rocket propulsion fuel according to the present invention comprises the rotating body part having a rotational axis insertion part, which is inserted into the rotational axis of a rotating device, formed to penetrate the center; and comprises, on the outer circumference of the rotating body part, a plurality of brushes for grinding and pulverizing propulsion fuel formed in a rocket. A plurality of brush insertion parts are arranged radially on the outer circumference of the rotating body part, wherein the lower ends of the brush insertion parts are opened and restrict the brushes not to move in the rotating direction of the rotating body part. The rotating body part has a screw part formed at a lower part and includes a coupling ring having a nut part coupled to the screw part to enable the upper end of the coupling ring to pressurize and fix the brushes vertically when the coupling ring is coupled to the rotating body part. |
