The invention discloses a pivot-adjustable gear-and-rack rock-loading bucket traction mechanism, and belongs to the field of loading and transport machines for mine roadways. The mechanism mainly comprises a framework, a bucket system, a basket system, an adjustable traction system and a storage bin. The mechanism integrates the functions of loading, transport and unloading, and the basket systemis driven by a chain to enable the bucket system to work; the adjustable traction system makes a chain wheel supporting arm stretch out and draw back under rack-and-gear transmission, and the length for which the chain wheel supporting arm stretches out and draws back is coupled with the motion of a bucket. The mechanism optimizes the working space of all the systems and integrates the functions of loading, transport and unloading; the motions of the mechanism do not mutually interfere on the premise that the occupied space is small, therefore, the mechanism can work with high efficiency in anadit with a narrow space, the technological dependence on workers is reduced, and the gangue collecting work is safer and more reliable.
