The unmanned spraying device for a green house in the present invention comprises guide rods arranged on the lower part of a ceiling frame of the green house by coupling pieces arranged in a certain interval to be vertically separated; a cart part moved along the guide rods; and a spray part installed in the cart part to spray chemicals. The cart part is characterized by comprising a body; an operating roller part including multiple operating rollers horizontally arranged in a line on the upper part of the body, circumscribed about the upper half part of the guide rods, and rotated by a rotatory force supplied from a driving motor; and a support roller part including multiple support rollers arranged to be separate from the lower part of the operating roller part to be rotated by being circumscribed about the lower half part of the guide rods circumscribed about the operating rollers. The cart part has the operating rollers of the operating roller part circumscribed about the upper half part of the guide rods, and has the support rollers of the support roller part circumscribed about the lower half part of the guide rods to be moved along the guide rods by operation of the operating rollers. |
