[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When spraying pesticides, traditional agricultural sprayers require the addition of pesticide solution, which means that the solution cannot be fully mixed with water and thus the sprayed pesticide cannot reach the specified concentration standard; 2. When spraying, traditional agricultural sprayers require the spraying range diameter to be adjusted according to the planting density of crops in the field, which requires the spraying structure to be able to adjust the spraying angle.

Then, the user can add the liquid medicine into the storage tank 12 through the medicine filling cylinder 4, and control the pressure inside the storage tank 12 through the pressure booster 3. At the same time, the liquid medicine inside the storage tank 12 moves upward, and after being atomized by the mist generator 11 inside the sealed pipe 6, it flows into the inside of the conical pipe 7. The water flow will be limited by the flow restrictor 14, and pass through the first spiral shaft 13 at a uniform speed to drive the first spiral shaft 13 to rotate and stir the mixture.
[0037] The water then flows through the inside of the separating pipe 8, splits, and flows to the inside of the rotating connecting arm 9. At the same time, it is stirred and mixed again by the rotation of the second spiral shaft 16 and sprayed out through the spray nozzle 10. The user can turn the adjustment knob 17 on the front of the rotating shaft 15, which drives the linkage gear 19 on one side to rotate through the worm gear assembly 18 and the belt, thereby driving the rotating connecting arm 9 to adjust the angle. The linkage gear 19 can be locked by sliding the sliding engagement ring 20 and the sawtooth block.
