PURPOSE: A snow removal device for a plastic greenhouse is provided to prevent snow from covering the upper side of a greenhouse, and damage the plastic cover. CONSTITUTION: A snow removal device for a plastic greenhouse comprises the following: a front frame(10) and a rear frame(20) located on the front and rear sides of the plastic greenhouse; a rotary shaft(30) rotatably supported by the front frame; a heat generating sheet(40) winded to the rotary shaft, covering the upper side of the plastic greenhouse, and generating heat to melt snow; first and second guide rails(62, 64) guiding the movement of the heat generating sheet by being installed in between the front and rear frames; a driver operating the rotary shaft, and a power supply unit(50) supplying power to the heat generating sheet. A storage case(32) for storing the heat generating sheet is installed on the front frame by fixing both ends of the storage case to the front frame. The storage case includes an inlet for inserting and discharging the heat generating sheet. The heat generating sheet includes a heat generating layer connected to the power supply unit, a heat transfer layer receiving the heat from the heat generating layer for melting the snow, a heat blocking layer located on the opposite side of the heat generating layer, and plural drain paths for discharging water generated from the melted snow.
