The invention discloses a tractor locking device, and relates to the technical field of tractors, a traction clamp and a tractor traction rod are provided with mounting holes, and pin shafts are movably connected with the mounting holes; the fixing plate is installed on the surface of one side of the traction clamp, threaded holes are formed in the upper surfaces of the locking handle and the fixing plate, and one end of the bottom fastening bolt penetrates through the threaded holes to be connected with the nut. According to the invention, the trailer can be simply and effortlessly hung on the tractor; meanwhile, the reliable locking of the fixed pin shaft is realized; the gravity of the object is fully downward, and the power moment is greater than the resistance moment to realize the self-locking principle, so that self-locking is realized; the rotating operation of the handle is used for replacing R pin dismounting, dismounting is convenient, a mounting hole of the R pin is not machined in the pin shaft any more, the material consumption and the machining amount are reduced, and cost is reduced.

    本发明公开了一种拖拉机锁紧装置,涉及拖拉机技术领域,本发明牵引卡以及拖拉机牵引杆均设有安装孔,销轴与安装孔活动连接;固定板安装于牵引卡一侧表面,锁紧手柄以及固定板上表面均设有螺纹孔,底紧固螺栓一端穿过螺纹孔与螺母连接。本发明不仅能够拖拉机在挂结拖斗时简单、省力;而且同时实现固定销轴的可靠锁紧;充分物体重力向下,动力力矩大于阻力力矩实现自锁的原理,实现自锁;利用手柄的旋转操作代替R销拆卸,又同时方便了拆卸,销轴不再加工R销的安装孔,减少材料用量和加工量,成本降低。
