The invention relates to the technical field of hinge type tractors, and discloses a hinge type tractor with a mire escape mechanism. The hinge type tractor comprises a tractor rear box, wherein the front side and the rear side of the tractor rear box are respectively provided with a mire escape mechanism and an escape screening mechanism; the mire escape mechanism comprises driving rollers, fixing discs, connecting rings, tires, arc-shaped holes, a first electric telescopic cylinder and an electric sliding ring; and the driving rollers are rotationally connected to the left side and the right side of the bottom of the tractor rear box, the fixing discs are fixedly connected to the front sides and the rear sides of the driving rollers, the connecting rings are welded to the outer sides of the fixing discs, the tires are movably connected to the outer sides of the connecting rings, and the arc-shaped holes are formed in the left side, the right side, the upper side and the lower side in each connecting ring. The arc-shaped plates and the electric telescopic cylinder are arranged in the connecting rings, when the hinge type tractor sinks into mire, the four unfolded arc-shaped plates are utilized, the contact area between tires and the mire is increased, the situation that the tractor rapidly sinks into the mire is avoided, and then the tractor escapes from the mire.

    本发明涉及铰链式拖拉机技术领域,公开了一种具有泥沼逃脱机构的铰链式拖拉机,包括拖拉机后箱,所述拖拉机后箱前后两侧设置有泥沼逃脱机构和逃脱筛分机构;所述泥沼逃脱机构包括驱动辊、固定盘、连接环、轮胎、弧形孔、第一电动伸缩缸和电动滑环;所述拖拉机后箱底部左右两侧均转动连接有驱动辊,所述驱动辊前后两侧均固定连接有固定盘,所述固定盘外侧焊接有连接环,所述连接环外侧活动连接有轮胎,所述连接环内部左右两侧和上下两侧均开设有弧形孔。本发明通过在连接环内设置弧形板和电动伸缩缸,可以在铰链式拖拉机陷入泥沼时,利用展开的四个弧形板,增加轮胎与泥沼的接触面积,避免快速陷入泥沼,从而从泥沼中脱出。
