The invention discloses a spare tire device and a rear scarifier of a land leveler. The spare tire device comprises a winch device, a fixing frame, an upper swing rod, a spare tire supporting frame and a lower swing rod, the fixing frame, the upper swing rod, the spare tire supporting frame and the lower swing rod are sequentially hinged to form a closed four-connecting-rod mechanism, the fixing frame is used for containing a spare tire, the fixing frame is connected with a working equipment support body, and the winch device controls the spare tire supporting frame to ascend and descend. The winch device comprises a lifting rope, a pulley and an electric winch, the pulley and the electric winch are both connected with the fixing frame, one end of the lifting rope is connected with the electric winch, and the other end of the lifting rope penetrates through the pulley to be connected with the spare tire supporting frame. The rear scarifier of the land leveler comprises the spare tire device, and the fixing frame of the spare tire device is connected with a rear scarifier body. The problems that in the prior art, replacement of a spare tire device wastes time and labor, and potential safety hazards exist are solved.
Description
technical field [0001] The invention relates to a spare tire device and a rear ripper for a grader, belonging to the technical field of construction machinery application. Background technique [0002] Motor graders are often used for expressway roadbed leveling and remote mining operations. These operations are usually far away from the suburbs, and graders work for nearly 10 hours a day. Mining graders are usually replaced without changing machines. Tires are common and vulnerable When replacing tires, it is usually necessary to drive to the designated factory. If the factory is far away, the construction period will be affected; [0003] The replacement of the spare tire usually requires the help of a professional service vehicle, which will have a certain waiting time, which will affect the progress of the construction period. The existing spare tire carrying device of the motor grader is too simple, and the carrying device has no power unit. When installing or removing ...
