PURPOSE: A snow removal device for a plastic greenhouse is provided to efficiently remove stacked snow by a reciprocating process of a housing installed with a snow removal wing, and an air blower through a guardrail installed on top of the greenhouse. CONSTITUTION: Frames(100) are installed along to the exterior of a plastic greenhouse, and are located at both ends of the plastic greenhouse(10). A guardrail(200) is fixed and installed on the surface of the frames, and a guide hole is formed on the sides. A housing(300) comprises at least one air blower(330) installed toward the top of the plastic greenhouse. A driving motor(310) is arranged in the housing, and delivers power to a driven axis. A snow removing wing(360) is installed adjacent to the top of the plastic greenhouse on the housing. A first sensor(220) controlling the device movement is comprised in each end of the guiderail. A second sensor detects stacked snow on top of the greenhouse. The controller(322) receives signals from the second sensor to operate the driving motor. The air blower is equipped with a heater. Between the air blower and the housing, a wind controller(340) is equipped to control the wind. The housing is comprised with an extra supporting pole comprised with a bearing of the driven axis. The snow removal wing is comprised with a brush forming waves through the longitudinal direction. |
