[0022] Reference Figures 1 - 4 Figures 1 - 4 , an embodiment provided by the utility model: a sealing structure of a quick-acting insecticide mixing tank, including a mixing tank body 1. Four feeding ports 11 are opened at the upper end of the mixing tank body 1. Four electric butterfly valves 12 are arranged inside the mixing tank body 1. The electric butterfly valves 12 are respectively fixedly connected to the inner side walls of the feeding ports 11 in a sealed manner. One end of the electric butterfly valve 12 away from the mixing tank body 1 is fixedly connected to a storage bin 13 in a sealed manner. A servo motor 17 is fixedly connected to the upper end of the mixing tank body 1. The output end of the servo motor 17 is fixedly connected to a threaded rod 18. A sealing cover 2 is threadedly connected to the side wall of the threaded rod 18. One end of the sealing cover 2 close to the servo motor 17 is fixedly connected to four second sealing rings 21. The second sealing rings 21 are respectively located directly above the storage bin 13. A telescopic rod 22 is fixedly connected to the lower end of the sealing cover 2. One end of the telescopic rod 22 away from the sealing cover 2 is fixedly connected to the upper surface of the mixing tank body 1.

[0023] This setting is to separately place different raw materials into the storage bin 13, and then start the servo motor 17, so that the servo motor 17 drives the threaded rod 18 to rotate, the threaded rod 18 drives the sealing cover 2 to move vertically downward, the sealing cover 2 drives the four second sealing rings 21 to move vertically downward, and the four second sealing rings 21 respectively seal the storage bin 13 at the same time. Then, the opening and closing of the electric butterfly valves 12 are controlled in sequence by an external controller, and the addition order is determined according to the solubility of the medicaments. Generally, it is arranged in the order of granule, wettable powder, suspension, aqueous solution, and emulsifiable concentrate. And when adding medicaments subsequently, the gas leaked outside the mixing tank body 1 enters the storage bin 13 and is sealed by the second sealing rings 21.

[0024] A first air outlet 201 is opened on the side wall of the sealing cover 2. Four air inlets 202 are opened at the lower end of the sealing cover 2, and the air inlets 202 are all located directly above the storage bin 13. A telescopic pipe 23 is arranged on the side wall of the sealing cover 2. The telescopic pipe 23 is fixedly connected to the inner side wall of the first air outlet 201 in a sealed manner. One end of the telescopic pipe 23 away from the sealing cover 2 is fixedly connected to an air suction machine 231 in a sealed manner. The output end of the air suction machine 231 is fixedly connected to an air purification component 3 in a sealed manner. A second air outlet 31 is fixedly connected to the side wall of the air purification component 3. It is used to, after the medicament addition is completed, start the air suction machine 231, so that the air suction machine 231 sucks out the gas leaked from the mixing tank body 1 to the storage bin 13 through the telescopic pipe 23, the first air outlet 201 and the air inlets 202, and then inputs it into the air purification component 3 and is discharged from the second air outlet 31 after being purified by the air purification component 3.

[0025] A limiting plate 24 is fixedly connected to the end of the threaded rod 18 away from the servo motor 17, which is used to limit the sealing cover 2 and prevent the sealing cover 2 from separating from the threaded rod 18.

[0026] Two mounting plates 14 are fixedly connected to the side wall of the storage bin 13. Ultrasonic generators 15 are fixedly connected to the adjacent side walls of the mounting plates 14. The ultrasonic generators 15 are used to vibrate the medicaments in the storage bin 13, accelerate the adding speed of the medicaments, and reduce the amount of gas generated by the mixing of the medicaments leaking out into the storage bin 13.

[0027] The inner ring diameter of the second sealing ring 21 is smaller than the diameter of the storage bin 13, and the outer ring diameter of the second sealing ring 21 is larger than the diameter of the storage bin 13. It is used to ensure the sealing performance at the connection between the second sealing ring 21 and the storage bin 13.

[0028] A first sealing ring 16 is fixedly connected at the connection between the electric butterfly valve 12 and the mixing tank body 1, which is used to increase the sealing performance at the connection between the electric butterfly valve 12 and the mixing tank body 1.

[0029] Working principle: First, different raw materials are respectively put into the storage bin 13. Then, the servo motor 17 is started. The servo motor 17 drives the threaded rod 18 to rotate. The threaded rod 18 drives the sealing cover 2 to move vertically downward. The sealing cover 2 drives the four second sealing rings 21 to move vertically downward. The four second sealing rings 21 respectively seal the storage bin 13 at the same time. Then, the opening and closing of the electric butterfly valve 12 are sequentially controlled by an external controller, and the adding order is determined according to the solubility of the medicaments. Generally, it is arranged in the order of granule, wettable powder, suspending agent, aqueous agent, and emulsifiable concentrate. And when subsequent medicaments are added, the gas leaking out of the mixing tank body 1 enters the storage bin 13 and is sealed by the second sealing ring 21. Then, when the addition of the medicaments is completed, the air suction machine 231 is started. The air suction machine 231 sucks out the gas leaking out of the mixing tank body 1 into the storage bin 13 through the telescopic pipe 23, the first air outlet 201, and the air suction port 202, and then inputs it into the air purification component 3. After being purified by the air purification component 3, it is discharged from the second air outlet 31.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
