LIQUID SPRINKLING APPARATUS IN PLANT GROWING HOUSE

PURPOSE:To attain cost reduction by setting the drive source of a running truck to one and to achieve the wt. reduction of a house by arranging a running passage change-over mechanism to the connection part of a running guide rail on a central side and a communication running passage and arranging a reversal mechanism to the other end part thereof and allowing one running truck to run on a plurality of running guide rails. CONSTITUTION:A plurality of running guide rails 1 are arranged to the upper part of a house in parallel and the endless wire 17 of an endless wire type transfer mechanism 5 is stretched over along said rails and the mutual end parts of the adjacent running guide rails 1 are connected on one side part of the house by communication running passages 2. Running passage change-over mechanisms 8 are arranged to the connection parts of the running guide rails 1b on the central side excepting the running guide rails 1a positioned on the outermost side among the running guide rails 1 arranged in parallel and the communication running passages 8 and reversal mechanisms 9 are arranged to the other end parts of said rails 1b. By this constitution, one running truck 3 equipped with a liquid sprinkler 4 successively runs on a plurality of the running guide rails 1 to sprinkle a liquid to the whole of the house.
