Detailed Implementation
[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] A portable agricultural directional spraying device, such as Figures 1-5As shown, the system includes a first liquid storage tank 1, pulleys 2, a second liquid storage tank 3, a third liquid storage tank 4, a handle 5, an injection pipe 6, a connecting pipe 7, a mounting bracket 8, a connecting shaft 9, a fixing plate 10, a volume controller 11, a nozzle 12, a twist cap 13, a mounting block 14, and a shoulder strap 15. The pulleys 2 are rotatably connected to the lower sides of both the front and rear of the first liquid storage tank 1. The second liquid storage tank 3 is connected to the left side of the first liquid storage tank 1 via a damping sliding mechanism. The third liquid storage tank 4 is also connected to the lower side of the third liquid storage tank 4 via a damping sliding mechanism. The first liquid storage tank 1, the second liquid storage tank 3, and the third liquid storage tank 4 are interconnected. The handle 5 is connected to the upper middle part of the first liquid storage tank 1, and the injection pipe is connected to the upper rear part of the first liquid storage tank 1. 6. The lower front of the first liquid storage tank 1 is connected to the connecting pipe 7 via a water pump. The upper front of the first liquid storage tank 1 is connected to two fixing plates 10, one above the other.
