[0011] The technical effects and advantages of this utility model are as follows:

[0012] Compared with the prior art, this utility model pressurizes the spray bar with a pressurizing device so that the spray bar sprays liquid to the outside. Then, the liquid vortex radius is adjusted by a variable diameter mechanism set on the surface of the spray bar nozzle. In this case, the connecting rod is rotated by a toggle block, so that the hose between the rotating plate and the base plate is gathered in the middle, thereby adjusting the liquid vortex radius.

[0018] Example 1

[0019] As attached Figures 1 to 3 The variable diameter vortex spray bar assembly for densely planted crops shown includes a connector 1, a handle 2 at one end of the connector 1, a connecting plate 4 at the end of the handle 2 away from the connector 1, a spray bar 5 at the end of the connecting plate 4 away from the handle 2, and a variable diameter mechanism 6 at the other end of the spray bar 5. The variable diameter mechanism 6 corresponds to the nozzle of the spray bar 5. A pressurizing device 3 is provided below the handle 2 and is connected to the spray bar 5.

[0020] Specifically: the spray bar 5 is pressurized by the pressurizing device 3 so that the spray bar 5 sprays liquid to the outside. Then, the liquid vortex radius is adjusted by the variable diameter mechanism 6 set on the nozzle surface of the spray bar 5. The connecting rod 12 is rotated by the toggle block 13, so that the hose 10 between the rotating plate 8 and the base plate 9 is gathered in the middle, thereby adjusting the liquid vortex radius.
