Abstract: A variable-rate spraying nozzle device includes a chemical supply assembly and an atomization spray assembly for atomizing and spraying a chemical solution. The atomization spray assembly includes spray housings arranged sequentially from top to bottom, chemical solution channels are provided between two adjacent spray housings, and the spray housings are assembled together to form an inverted tapered exterior structure; spray holes are densely and circumferentially provided in each spray housing; spray housings are connected with an atomization power mechanism including atomization rotation shafts and a power mechanism including motors and transmission mechanisms for connecting main spindles of the motors with the atomization rotation shafts correspondingly; the atomization rotation shafts in the atomization power mechanism corresponding to the spray housings are coaxially disposed; the motors in the atomization power mechanism are connected with a speed control module.
