| 简介 |
PURPOSE : A device for guiding taking-up of a plastic film for opening or closing a green house to help to closely and tightly roll-up the plastic film around the winding axis, to prevent the winding axis from being swayed or affected by the wind on the roof top of the green house, thereby preventing the wound-up plastic film from being swelled or torn by the wind, and to allow the snow or rain to get into the earth in the green house so as to maintain fertility of the earth for prolonged period, and improve the growth of the crops or plants in the green house.
CONSTITUTION : The device for guiding taking-up of a plastic film for opening or closing a green house comprises : a winding axis which takes up the plastic film covering the green house by using a motor; a main body(10) where a hollow space for receiving the wound-up plastic film is formed along the lengthwise direction thereof; guiding segments(12, 13) which are integrally formed protruded from one side of the body so as to have a guiding passage(14) for the plastic film, and to communicate with the hollow space on the imaginarily extended vertical line; and at least two coupling rings(15) for holding a weight at the lower part of the main body.
