[0002] When working, the traditional pesticide sprayer first mixes the pesticide agent with water to prepare a pesticide aqueous solution, pours it into the liquid storage barrel of the sprayer, and is carried by personnel to the spraying area for spraying. When the existing pesticide sprayer is in use, the amount of the pesticide solution is not easy to grasp. If the amount of the pesticide solution is not enough, it needs to be configured multiple times, which is troublesome to operate. Therefore, in practice, a large amount of pesticide solution is often configured once, but this will lead to the situation that the pesticide solution is not used up. This configured pesticide solution cannot be stored for a long time, which will lead to the waste of pesticides. At the same time, the liquid storage barrel of the existing pesticide sprayer has a small barrel mouth and a deep barrel body, which is difficult to clean after the spraying is completed, and it is easy to cause the liquid to remain. In addition, in the process of spraying, it is often encountered that the local area is more serious in insect pests, and the concentration of the pesticide aqueous solution needs to be increased. The traditional pesticide sprayer cannot complete the spraying at one time, and can only re-prepare the pesticide aqueous solution and spray again. Utility Model Content

In addition, after the spraying operation is completed, the unused medicine box 6 can be removed for storage, and the medicine box 6 filled with clean water can be replaced to perform the above-mentioned spraying action, so that the mixed medicine component, the spray component and the intermediate pipeline can be cleaned, and the cleaning process is also more convenient.

[0022] When implementing:

[0023] The above-mentioned spray assembly also includes a pressure pump 11, the suction end of the pressure pump 11 is connected to the liquid outlet pipe 10, and the discharge end of the pressure pump 11 is connected to the end of the spray pipe 2 away from the nozzle 3. When the pressure pump 11 is running, the medicine in the mixed liquid shell 8 can be pumped into the spray pipe 2 and then sprayed out from the nozzle 3 at the front end.

[0024] The liquid mixing housing 8 is also connected with an air vent 12, which is used to balance the air pressure in the liquid mixing housing 8, so that the medicine mixing pump 7 and the water mixing pump 5 can smoothly pump the medicine and water into the liquid mixing housing 8 according to accurate dosages, and the pressure pump 11 can spray the medicine smoothly.

[0025] The aforementioned stirring member includes a stirring shaft 13, which is rotatably arranged in the liquid mixing housing 8, and a plurality of stirring blades 14 are arranged at intervals on the stirring shaft 13, and the liquid medicine and water are mixed evenly by the rotation of the stirring shaft 13. In specific implementation, a driving motor can be separately arranged, and the stirring shaft 13 can be driven by the driving motor to rotate to achieve uniform liquid mixing; in addition, the positions of the liquid inlet pipe 9 and the liquid outlet pipe 10 can also be specifically arranged, so that the liquid inlet pipe 9 and the liquid outlet pipe 10 are both arranged along the rotation tangent direction of the stirring member, when the drug mixing pump 7 and the water mixing pump 5 pump the liquid medicine and water into the liquid mixing housing 8 through the liquid inlet pipe 9, the stirring blades 14 can be impacted to achieve stirring, and when the booster pump 11 extracts the liquid medicine from the liquid mixing housing 8, the stirring shaft 13 can also be driven to rotate to achieve stirring.

[0026] Furthermore, the flow rate of the aforementioned medicine mixing pump 7 is adjustable, and the concentration of the medicine solution in the medicine solution can be changed by adjusting the flow rate of the medicine mixing pump 7. For example, during the spraying process, when encountering that some areas are seriously affected by pests and diseases and it is necessary to increase the concentration of pesticides in the medicine solution, the medicine mixing pump 7 and the water mixing pump 5 can be closed first, and the medicine solution in the mixed liquid housing 8 can be sprayed and drained, and then the flow rate of the medicine mixing pump 7 is increased, and then the medicine mixing pump 7 and the water mixing pump 5 are opened for spraying, and at this time, the high-concentration medicine spraying operation is performed.

[0027] Furthermore, a control box 15 is provided on the top of the housing 1, and a battery and a controller are provided in the control box 15. A high-level liquid gauge and a low-level liquid gauge are provided in the liquid mixing housing 8.

At this time, the medicine mixing pump 7 and the water mixing pump 5 automatically operate under the control of the controller. Specifically: when the liquid level in the mixing liquid shell 8 is lower than the high liquid level (the detection position of the high liquid level gauge), the controller can control the medicine mixing pump 7 and the water mixing pump 5 to continue to operate to mix medicine; when the liquid level in the mixing liquid shell 8 is at the high liquid level, the medicine mixing pump 7 and the water mixing pump 5 both stop running to prevent the medicine in the mixing liquid shell 8 from overflowing from the air vent 12; when the liquid level in the mixing liquid shell 8 is lower than the low liquid level (the detection position of the low liquid level gauge), the booster pump 11 is prohibited from operating to prevent it from sucking air and causing uneven spraying.

[0030] When spraying is finished and concentration adjustment, cleaning, etc. are required, the mode switching button 17 is adjusted to the emptying mode. At this time, the medicine mixing pump 7, the water mixing pump 5, and the booster pump 11 are not restricted by the liquid level. The medicine mixing pump 7 and the water mixing pump 5 are in a stopped state. The booster pump 11 can continue to operate when the spray button 16 is operated to drain the liquid in the mixing liquid shell 8.
