Detailed Implementation
[0017] 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.
[0018] Please see Figure 1-4This utility model provides a technical solution: an adjustable-angle pesticide filling anti-drip guide device, including a guide pipe 1 and a connector 4. A flexible conduit 2 connects the guide pipe 1 and the connector 4. The outer end of the guide pipe 1 is provided with a connecting circular plate 3 for installing the connector 4. The connection between the connecting circular plate 3 and the outer end of the guide pipe 1 is connected by a rotating assembly consisting of a rotating sleeve 8 and a rotating column 9. The rotating sleeve 8 is welded and fixed to the outer end of the guide pipe 1, and the rotating column 9 is welded and fixed to the connecting end face of the connecting circular plate 3. The rotating column 9 extends into the interior of the rotating sleeve 8 and is fitted by a limiting ring. The outer end of the guide pipe 1 is also provided with a tension limiting mechanism 7 for quickly fixing the connecting circular plate 3 after the angle is adjusted by rotation. The bottom end of the connecting circular plate 3 is provided with an upper sealing ring 5 and a lower sealing ring 5. The lower sealing ring 6 is movably positioned outside the upper sealing ring 5, and its upper part is also movably fitted onto the outside of the connector 4. A sealing gasket is bonded and fixed to the edge of the lower sealing ring 6's outer end. The upper sealing ring 5 and the lower sealing ring 6, fitted onto the outside of the connector 4, form a dynamic sealing structure. When the filling angle of the connector 4 needs to be adjusted at the outer end of the guide tube 1, the operator can easily adjust the angle of the connecting plate 3 using the rotating sleeve 8 and rotating column 9 of the rotating assembly. Simultaneously, the tension limiting mechanism 7 can quickly lock the adjusted angle of the connecting plate 3, ensuring the stability of the connector 4's position during filling. The upper sealing ring 5 and the lower sealing ring 6 can cooperate to flexibly press against the outside of the container's filling port, ensuring a tight fit between the connector 4 and the container, even when... Even after adjusting the angle of connector 4, a good sealing effect can be maintained, effectively reducing pesticide dripping and overflow, lowering the risk of environmental pollution and operator contact with pesticides, making the pesticide filling process safer, more convenient, and more environmentally friendly. This solves the dripping problem commonly found in existing pesticide filling equipment, improving filling efficiency and safety. A strip groove is provided on one side of the connecting circular plate 3, and a flipping component 11 is provided within the strip groove. The inner end of the flipping component 11 is movably connected to the inner wall of the strip groove of the connecting circular plate 3 via a pin. The top of connector 4 is screwed to the bottom wall of the flipping component 11, and the top of the flipping component 11 is connected to the inside of the top of the strip groove of the connecting circular plate 3 via an elastic sheet 10. This structure allows operators to adjust the connection. The rotating part 11 changes the angle of the connector 4. During angle adjustment, the elastic sheet 10 can quickly respond using its toughness and support further precise adjustment of the angle of the connector 4, thereby achieving a better tight fit between the connector 4 and the container, reducing the risk of pesticide leakage, and meeting the needs of efficient and safe filling of containers of different shapes and sizes. The tension limiting mechanism 7 includes a fixed ring 71 fixedly sleeved on the outside of the outer end of the guide tube 1. A movable ring 72 is provided on the outside of the fixed ring 71 and movably sleeved on the outside of the outer end of the guide tube 1. Hand push rings are welded and fixed on both sides of the movable ring 72. A compression spring 73 is provided between the fixed ring 71 and the movable ring 72 and is also sleeved on the outside of the outer end of the guide tube 1. The outer edge of the movable ring 72 is symmetrically provided with locking posts 74.Furthermore, the inner end face of the connecting circular plate 3 is provided with several locking holes that match the structure of the locking post 74. When it is necessary to adjust the angle of the connecting circular plate 3 and lock its position, the operator can move the movable ring 72 towards the fixed ring 71, thereby squeezing the compression spring 73, causing the locking post 74 to disengage from the locking hole currently engaged on the inner end face of the connecting circular plate 3, allowing the connecting circular plate 3 to be adjusted in angle. Once the required angle is reached, the movable ring 72 is released, and under the restoring force of the compression spring 73, the movable ring 72 moves outward, causing the locking post 74 to re-engage in the corresponding locking hole, thus achieving a stable lock on the connecting circular plate 3 and its components, effectively preventing angle deviation caused by external interference, ensuring sealing effect and filling efficiency. The outer wall of the top of the lower sealing ring 6 is provided with a slider 12, and the inner walls on both sides of the lower end of the upper sealing ring 5 are provided with grooves that cooperate with the structure of the slider 12. Furthermore, the inner walls on both sides of the upper sealing ring 5 are connected to the top of the lower sealing ring 6 by support blocks. A spring 13 connects the walls. In this structure, when the lower sealing ring 6 contacts the container filling port and needs to adapt to containers of different shapes and sizes, i.e., when the lower sealing ring 6 presses against the container, it drives the slider 12 to slide along the grooves on both sides of the lower end of the upper sealing ring 5 for appropriate displacement adjustment. Simultaneously, the spring 13 provides the necessary elastic support force to ensure that the lower sealing ring 6 can tightly fit the container surface, forming a good sealing effect. This automatically adjusts the pressure according to the actual contact situation, ensuring a tight fit between the upper and lower sealing rings 5 and good adaptability to the container surface. A mating ring 14 is provided at the bottom edge of the connecting circular plate 3, and the top of the upper sealing ring 5 is inserted into the mating ring 14 and fixed with bolts. When equipment maintenance, cleaning, or replacement of upper and lower sealing rings 5 and 6 of different sizes to adapt to different container filling ports is required, the upper sealing ring 5 can be easily removed from the mating ring 14 simply by loosening the bolts, making the operation simple and quick.
[0019] Working principle: When using this adjustable-angle pesticide filling anti-drip diversion device, the operator first needs to adjust the angle of the connector 4 according to the specific shape and size of the container to be filled. This is achieved by manually rotating the rotating assembly consisting of the rotating sleeve 8 and the rotating column 9, which easily adjusts the angle of the connecting plate 3, thereby changing the position of the connector 4 for better alignment with the container filling opening. Once a suitable angle is found, the operator pushes the movable ring 72 towards the fixed ring 71, causing the locking pin 74 to disengage from the locking hole on the connecting plate 3, allowing for free adjustment. After adjustment, the movable ring 72 is released, and under the restoring force of the compression spring 73, the locking pin 74 re-engages into the corresponding position. Inside the locking hole, the connecting disc 3 and its components are securely locked. If the seal between the connector 4 and the container is not complete or further fine-tuning is required, the elastic sheet 10 can be used to adjust the flipping part 11 to precisely adjust the angle of the connector 4. Next, the connector 4 is brought close to the container filling port. When the lower sealing ring 6 presses against it, it will drive the slider 12 to slide along the grooves set on the inner walls of the lower end of the upper sealing ring 5. During this process, the spring 13 provides the necessary elastic support force. The upper sealing ring 5 and the lower sealing ring 6 ensure the best sealing performance. After all adjustments are completed and the seal is confirmed to be good, the pesticide filling operation begins, thus completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
