The invention relates to a rear axle structure of a cotton picker. The invention belongs to the technical field of agricultural machinery. The rear axle structure comprises a rear axle main beam, twotires, a steering wheel shaft, a steering crank arm, a hub and a rim. The rim is installed on the hub, a thrust bearing is arranged between the hub and the steering wheel shaft, a two-way oil cylinderis arranged on a rear axle main beam, and when the two-way oil cylinder extends, an included angle a enabling the two tires to be in an inverted splayed state is formed between the hub and a ground vertical line. The rear axle structure has the advantages that the states of the tires and the ground are controlled through the two-way oil cylinder arranged on the rear axle main beam; specifically,when the cotton picker needs to turn, the tires are in an inverted splayed state through stretching of the two-way oil cylinder, so that the tires and the ground form a certain inclined structure, andthe contact area of the tires and the ground is reduced; in addition, the invention further discloses a cotton picker which comprises the rear axle structure.

    本发明涉及一种采棉机的后桥结构,属于农用机械技术领域,包括后桥主梁、两个轮胎、转向轮轴、转向拐臂、轮毂和轮辋,轮辋安装在轮毂上,轮毂与转向轮轴之间设有推力轴承,后桥主梁上设有双向油缸,当双向油缸伸展时所述轮毂与地面垂直线之间形成一个使两个轮胎呈倒八字状态的夹角a;本发明的优点:通过后桥主梁上设置的双向油缸来控制轮胎与地面的状态,具体的,当采棉机需要转弯时,通过双向油缸的伸展,使轮胎呈倒八字状态,从而使轮胎与地面呈一定的倾斜结构,从而减少了轮胎与地面的接触面积;另外,本发明还公开了一种采棉机,包括上述所述的后桥结构。
