The invention belongs to the technical field of water-saving irrigation of a farmland, and particularly relates to a folding type secondary irrigation water distribution device with an adjustable water amount of a three-dimensional space. Secondary distribution can be performed for irrigation water, pressure and pulsation can be reduced due to arrangement of branch pipes, and the consistency of the pressure difference of every branch pipe and the uniformity of water sprayed by every nozzle can be improved. The opening/closing and the spraying amplitude of a single nozzle can be adjusted separately by a user according to actual conditions, included angles of two end sections and a middle section of a folding device can also be adjusted, and the amount of irrigation water of the three-dimensional space can be adjusted in combination with adjustment of the running speed of an irrigation vehicle. The structure of a pipeline and the requirements of pipe diameters are set according to fluid analysis and needs of us
