A cylinder protection device for a wheel type excavator dozer blade is provided to have a simple structure, easy maintenance, and a low defect rate, and to reduce noise in operation by forming a diffraction link whose one end is hinged at a rotation center of a hydraulic cylinder located at an upper portion of a fixed frame, and a protection cover having a two-joint structure where one end is hinged to the other end of the diffraction link and the other end is hinged to an upper part of the blade. A wheel type excavator dozer blade(4) ascends and descends by operation of a hydraulic cylinder(6) which is connected to a fixed frame(1) and multiple upper and lower links(3,2), and whose one end is hinged to the fixed frame and the other end(60) is hinged to the lower link. A cylinder protection device for a wheel type excavator dozer blade comprises a protection cover(51) whose one end(54) is hinged to an upper part of the blade, and a diffraction link(50) whose one end(52) is hinged to the other end of the protection cover and the other end(53) is hinged to an upper portion of the fixed frame to be in conformity with a rotation center of the hydraulic cylinder, and rotates according to operation of the hydraulic cylinder. |
