The invention discloses a
plant factory adopting double-rotation mist spray planting. The factory includes a box-type main body. The box-type main body is internally provided with support frames, a cultivation main body, a rotating device, a
nutrient solution circulation device, a light supplementing device, a ventilation device and an
electric control device. The support frames are installed on the two sides of the inner wall of the box-type main body, and the cultivation main body includes an upper cover, a planting
barrel body, a lower cover and connection screw rods. The rotating device includes an autorotation contact point, a hook, a rotating bearing, a bearing fixing frame, a driving motor, a driving wheel, driven wheels, a chain and a chain rail. The
nutrient solution circulation device includes a
liquid storage tank, a water pump, a liquid supply
pipe, a liquid supply turntable, a return
water pipe, a
water collection tank, a centralized
reflux pipe and atomizing nozzles. Theventilation device comprises vent holes, air inlets and exhaust fans. The light supplementing device includes a light-supplementing lamp and foldable brackets. The
plant factory adopts three-dimensional planting, the yield per unit area is increased, the cultivation main body adopts two
modes of autorotation and revolution so that the problem of non-uniform
plant lighting can be solved better, andthe factory adapts to urban communities, residential roofs and island frontier areas and has the advantages of being convenient, efficient, simple in operation and the like.
