Folding type secondary irrigation water distribution device with adjustable water amount of three-dimensional space

Abstract

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 users, so as to achieve the best uniformity. The device can be installed on the majority of vehicles for irrigation devices. Since the easy-to-operate folding device is adopted, the width of the water spraying area can be adjusted, the irrigation density of the middle section can be increased, and the space of the whole vehicle-mounted device can also be saved effectively. The device has the advantages of good adaptability and flexible configuration, and is conducive to promotion of the water-saving irrigation technique.

Description

technical field [0001] The invention belongs to the technical field of farmland water-saving irrigation, and particularly relates to a foldable irrigation water secondary distribution device with adjustable water volume in a three-dimensional space. Background technique [0002] The effective use of irrigation water is the goal of modern water-saving agricultural research. The use of advanced engineering technology can improve the distribution uniformity of irrigation water, improve the utilization rate of farmland irrigation water and water production efficiency, increase crop yield, and reduce water waste. To ensure the sustainable and stable development of agriculture. [0003] The main factor affecting the uniformity of water distribution in the field is the water distribution characteristics of the nozzles at the water outlet. When the traditional primary irrigation water distribution device is spraying with a large flow rate, due to the long single pipeline and the lar...
