A traction machine with changeable and adjustable crawler belt shapes belongs to the technical field of agricultural machinery and comprises a traction machine body, a driving unit and a transmission unit, the driving unit and the transmission unit are arranged on the traction machine body, and the transmission unit comprises a crawler belt, a fixed wheel, a tensioning wheel and a land wheel, the tensioning wheel is switched between the position of the horizontal line where the fixed wheel is located and the position of the horizontal line where the land wheel is located by means of a switching mechanism, and the switching mechanism comprises a first connecting rod and a second connecting rod which are hinged to the machine body and is further provided with a third connecting rod hinged between the first connecting rod and the second connecting rod. The conversion structure further comprises a first telescopic device and a second telescopic device which are arranged on the machine body, the first telescopic device is connected with the lifting point, and the second telescopic device is connected with the second connecting rod. By arranging the switching mechanism, the tensioning wheel forms displacement, the shape of the crawler belt can be freely switched according to the property of the field, and therefore the contact area between the crawler belt and the field can be selectively increased or decreased.

    一种履带形状变换可调的牵引机,属于农业机械技术领域,包括牵引机机体以及设于所述机体上的驱动单元和传动单元,传动单元包括履带及包覆于履带中且与之配合的固定轮、张紧轮和地轮,所述张紧轮借助转换机构在固定轮所在水平线和地轮所在水平线的位置之间进行切换,所述转换机构包括与机体铰接的第一连接杆和第二连接杆,还设有铰接于第一连接杆与第二连接杆之间的第三连接杆,转换结构还包括设于机体上的第一伸缩装置和第二伸缩装置,所述第一伸缩装置与提拉点连接,第二伸缩装置与第二连接杆连接。通过设置转换机构使张紧轮形成位移,可以根据田地的性质自由切换履带的形状,从而选择增加或减少履带与田地之间的接触面积。
