<p>PURPOSE: A device for opening and closing a heat insulation cover for a plastic greenhouse is provided to have a double-clutch mounted on one fixed motor instead of using two motors. CONSTITUTION: A double-clutch(200) is connected to a motor(100) to convert and drive two shafts. A winding shaft(300) of a heat insulation cover is connected to the double-clutch, and coils the heat insulation cover. The heat insulation cover(400) is coiled on the winding shaft. A tug(500) is connected to the end of the heat insulation cover to assist the uncoiling. A tug roller(600) switches the direction of the tug in uncoiling the heat insulation cover. A tug winding shift(700) is connected to the double-clutch to coil the tug which has passed through the tug roller. A controller(800) is connected to the motor and the double-clutch, and controls the driving of a device. A winding support box(710) is fixed to a ring, and supports the coiled heat insulation cover. A roller(711) presses the heat insulation cover when the heat insulation cover is coiled and uncoiled.</p> |
