[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: an anti-volatile sealing structure for a pesticide liquid storage tank, comprising an anti-volatile sealing structure body 1 and a pesticide liquid storage tank 3. The anti-volatile sealing structure body 1 is provided with a sealing snap-fit ​​seat 2, and an inlet / outlet pipe 6 passes through the sealing snap-fit ​​seat 2. A pipe sealing ring 601, which is tightly snapped onto the inlet / outlet pipe 6, is fitted onto the inlet / outlet pipe 6. The pesticide liquid storage tank 3 has an integrally formed tank opening 302 at its upper end, and the sealing snap-fit ​​seat 2 is sealed and snapped into the tank opening 302. A sealing cover 301, threadedly connected to the tank opening 302, is also provided above the pesticide liquid storage tank 3. A cover sealing ring 303, which seals and cooperates with the tank opening 302, is fitted inside the sealing cover 301. A fixed fixture corresponding to the position of the inlet / outlet pipe 6 is fixed at the upper end of the sealing snap-fit ​​seat 2. The positioning seat 5 has a fixed cylinder 501 integrally installed on its upper end, and an anti-volatile sealing hose 4 runs through the fixed cylinder 501. The anti-volatile sealing hose 4 is made of the same material as the rubber fastener 8, and a pipe fitting connector 7 is sealed and snapped onto the upper end of the anti-volatile sealing hose 4. The lower end of the anti-volatile sealing hose 4 is sleeved on the outside of the inlet / outlet pipe 6, and the bottom of the anti-volatile sealing hose 4 is in close contact with the pipe fitting sealing ring 601. This structure, through the hose structure of the anti-volatile sealing hose 4, allows the middle section of the anti-volatile sealing hose 4 to close inward, thereby sealing the inlet / outlet pipe 6 and effectively preventing the evaporation of pesticide liquid. At the same time, the main body 1 of the anti-volatile sealing structure also provides a double seal through the sealing cap 301 to improve the anti-volatile sealing effect. The pipe fitting sealing ring 601 can seal the inlet / outlet pipe. The tube 6 is sealed to the anti-volatile sealing hose 4. On opposite sides of the positioning seat 5 are rubber fasteners 8 that contact and engage with the anti-volatile sealing hose 4. The rubber fasteners 8 have a triangular structure, and their opposite sides have complementary arc-shaped structures. This structure allows the rubber fasteners 8 to move towards the center, where the arc-shaped structure locks the anti-volatile sealing hose 4, creating a wave-like structure at the closed portion of the hose 4, improving the sealing effect and thus enhancing anti-volatile performance. The other side of the rubber fastener 8 is fixed with a limiting rod 12 by welding, and the limiting rod 12 is movably connected to the fixed cylinder 501. This structure allows the rubber fastener 8 to be moved and limited relative to the fixed cylinder 501 by the limiting rod 12, thus improving anti-volatile performance. The middle section of the sealing hose 4 is closed. A movable connecting plate 10 is fixed to the outer end of the limiting rod 12 by screws. A double-helix drive screw 11 passes through the side of the movable connecting plate 10 via a threaded structure. The double-helix drive screw 11 is located outside the fixed cylinder 501, and positioning plates 9 are rotatably connected to both ends of the double-helix drive screw 11. This structure allows the double-helix drive screw 11 to rotate under the positioning of the positioning plates 9, enabling the double-helix drive screw 11 to move and adjust the movable connecting plate 10. The movable connecting plate 10 on the same double-helix drive screw 11 moves in opposite directions through a bidirectional anti-helix structure, thereby adjusting the spacing of the rubber fasteners 8. This allows the anti-volatile sealing hose 4 to be opened during material feeding and discharging.The positioning plate 9 and the positioning seat 5 are integrally formed, and the movable connecting plate 10 is arranged parallel to the positioning plate 9. The fixed cylinder 501 is supported at the lower end of the pipe fitting connecting seat 7. This structure, through the positioning seat 5, forms the external support and positioning structure for the anti-volatile sealing hose 4. The length of the anti-volatile sealing hose 4 is greater than the height of the fixed cylinder 501, ensuring that the anti-volatile sealing hose 4 has sufficient closing distance to prevent the anti-volatile sealing hose 4 from falling off.

[0018] Working principle: When using the anti-volatile sealing structure of this pesticide liquid storage tank, firstly, when storing liquid pesticides, the sealing snap-fit ​​seat 2 snaps into the tank opening 302, which is used for the installation and positioning of the main body 1 of the anti-volatile sealing structure. The inlet and outlet pipes 6 pass through the sealing snap-fit ​​seat 2 and are sealed and fastened by the pipe fitting sealing ring 601, respectively for the inlet and outlet of the liquid pesticides. During the storage of liquid pesticides, the double helix drive screw 11 rotates under the positioning plate 9, allowing the movable connecting plate 10 to drive the rubber fasteners 8 to move through the limit rod 12, shortening the spacing of the rubber fasteners 8 until... The middle section of the anti-volatile sealing hose 4 is tightly closed, and the complementary arc structure between the rubber fasteners 8 improves the sealing tightness of the anti-volatile sealing hose 4 and enhances its anti-volatile performance. The anti-volatile sealing hose 4 is positioned by the fixing cylinder 501 and fastened to the sealing snap-fit ​​seat 2 by the positioning seat 5. After the sealing cover 301 is engaged with the cover body sealing ring 303, the sealing cover 301 is connected to the tank opening 302 by a threaded connection to achieve multiple seals. When feeding or discharging material again, the sealing cover 301 is opened to allow the rubber fasteners 8 to move away from each other, and then the pipe fitting connecting seat 7 is connected to the inlet / outlet pipe 6 to complete a series of operations.
