Mechanical structure for crop carrying

The utility model relates to a mechanical structure for crop carrying. The mechanical structure comprises a machine frame. The mechanical structure is characterized in that a spline shaft capable of rotating relative to the machine frame is longitudinally arranged on one side inside the machine frame, a screw rod is longitudinally arranged on the other side of the machine frame and sleeved with a lifting nut, the lifting nut is fixedly connected with a lifting table slidably connected with the spline shaft, the lifting table is provided with a rotating arm, a telescopic mechanism arm is hinged to the rotating arm, a tail end mechanism arm is hinged to the telescopic mechanism arm, and an end effector for carrying crops is hinged to the tail end mechanism arm. The mechanical structure is simple and convenient to operate, farmer's labor in carrying the crops is saved, working efficiency of the farmland operation process is accelerated, and the mechanical structure is favorable for boosting whole farmland production mechanization and automation.
