[0019] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] See also Figure 1-4A new type of spray control valve provided by an embodiment of the utility model includes a frame 8 and a medicine box 1. The medicine box 1 is fixed on the frame 8. A water pump 2, a pressure regulating valve 3, a distributor 4 and a filter 5 are also fixedly connected to the frame 8. The water outlet port of the medicine box 1 is connected to the filter 5 through a water supply pipe 11, and the water outlet port of the filter 5 is connected to the water pump 2 through a pipeline. The water outlet port of the water pump 2 is connected to the water inlet port on the distributor 4 through an inlet pipe 41. A pressure regulating valve 3 is installed on the distributor 4, and the pressure regulating valve 3 is communicated with the distributor 4. The water outlet port of the pressure regulating valve 3 is connected to the water pump 2 through a return pipe 42, and the water outlet port of the return pipe 42 is connected to the side wall of the pipeline. The water outlet port on the distributor 4 is respectively connected to one end of a stirring pipe 91 and one end of a water outlet pipe 6, and the other end of the stirring pipe 91 is connected to a stirrer 9. The stirrer 9 is arranged in the medicine box 1 and fixedly connected to the inner side wall of the medicine box 1.

[0021] The distributor 4 is provided with a pressure gauge 7 for displaying the liquid pressure.

[0022] A plurality of water outlet ports are fixedly connected to the bottom end of the distributor 4, and one of the water outlet ports is connected to the stirring tube 91, and the remaining water outlet ports are connected one by one to a plurality of water outlet pipes 6, and the plurality of water outlet pipes 6 are respectively connected to the left spray rod, the middle spray rod and the right spray rod on the sprayer, so that while the liquid medicine flows to the spraying device through the water outlet pipe 6, part of the liquid medicine can also flow back into the medicine box 1, and in the process of flowing back to the medicine box 1, the liquid medicine in the medicine box 1 is jet-stirred, thereby ensuring that the liquid medicine in the medicine box 1 is fully mixed.

[0023] The water outlet port of the return pipe 42 is connected to the pipe connecting the filter 5 and the water pump 2 to form a three-way pipe, so that the returned liquid medicine directly passes through the water pump 2 and enters the distributor 4 without secondary filtration of the liquid medicine.

[0024] During use, the frame 8 is first fixed on the sprayer, and then the medicine box 1, the water pump 2, the pressure regulating valve 3, the distributor 4 and the filter 5 are sequentially installed and fixed on the frame 8, and the water outlet port of the distributor 4 is respectively connected to the left spray rod, the middle spray rod and the right spray rod on the sprayer through the water outlet pipe 6. When the water pump 2 is working, the liquid medicine in the medicine box 1 is extracted, and after being filtered by the filter 5, it reaches the water pump 2, and then flows from the water pump 2 to the pressure regulating valve 3. The pressure regulating valve 3 controls the pressure inside the system by rotating the two pressure regulating handles, and the pressure inside the pressure valve The force can be displayed by the pressure gauge 7. When the pressure reaches the required requirement, the liquid will flow out of the water outlet pipe 6 and the stirring tube 91 through the distributor 4 respectively. The medicine liquid flowing out of the water outlet pipe 6 will eventually flow to the spraying device and be sprayed by the nozzles on the left spray rod, the middle spray rod and the right spray rod to spray the seedlings. The medicine liquid flowing out of the stirring tube 91 will flow to the agitator 9 and be sprayed by the agitator 9, thereby performing a jet stirring operation on the medicine liquid inside the medicine box 1, realizing real-time stirring of the medicine liquid in the medicine box 1 and ensuring sufficient mixing of the medicine liquid.
