Folding three-prism-shaped spray rod atomizing frame and operation method thereof

The invention provides a folding three-prism-shaped spray rod atomizing frame and an operation method thereof. Spray rod big arms are hinged to two ends of a spray rod middle section through first hinging structures, and big arm expansion driving mechanisms for driving the spray rod big arms to rotate around the first hinging structures are mounted between the spray rod big arms and the spray rodmiddle section; and big arm hinging plates are fixed on the side walls of the tail ends of the spray rod big arms and are hinged with one ends of small arm hinging plates through third pin shafts, thesmall arm hinging plates are fixedly mounted on spray rod small arms, and double crank driving mechanisms for driving the spray rod small arms to be unfolded are mounted among the spray rod big arms,the big arm hinging plates and the small arm hinging plates. The atomizing frame can be matched with an atomizing vehicle in use and is used for spraying medicines to crops; and the atomizing frame utilizing a multi-stage fold
