description The invention discloses an opening and closing device of a scuttle at the top end of a greenhouse. The scuttle comprises a frame and a cover, and the frame and the cover are connected through a hinge. The opening and closing device comprises a mechanical pushing rod composed of a pushing rod, an outer cover, a lead screw, a first limit switch, a second limit switch, a direct current motor and a speed reducer. The direct current rotor drives the lead screw to rotate through the speed reducer, the lead screw drives the pushing rod to move up and down, the pushing rod is connected with a first installation base through a first cylindrical pin, the pushing rod is installed on the cover through the first installation base, and linear motion of the pushing rod is converted into rotation of the cover through the first cylindrical pin. The opening and closing device of the scuttle at the top end of the greenhouse can open and close the scuttle of the greenhouse automatically, is simple in structure, strong in environ
