[0002] In agricultural production, pests and diseases are among the main factors affecting crop yield and quality. To effectively control pests and diseases, spraying chemical pesticides or biological agents is currently the most common measure. The effectiveness of the application equipment directly affects the control effect, pesticide utilization rate, and environmental impact.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the application tube equipped with existing crop pest control application devices is usually a long integral structure with a fixed length that cannot be adjusted or shortened. This makes it difficult to effectively store the application tube during daily storage and transportation, and it occupies a large space. In addition, the excessively long application tube is prone to bending or even damage due to external impact during operation and handling, which in turn affects the normal use of the equipment. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing technology has the disadvantage that the length of the pesticide application tube is fixed and cannot be adjusted to shorten it. Therefore, we propose a pesticide application device for crop diseases and pests.

[0021] A connecting assembly is installed at the near ends of the first application tube 5 and the second application tube 6. The connecting assembly includes a connecting tube 10 installed at the adjacent ends of the first application tube 5 and the second application tube 6. Both ends of the connecting tube 10 are fixed with connecting blocks 9. The ends of the first application tube 5 and the second application tube 6 near the connecting blocks 9 are provided with mounting grooves 8 that are threadedly connected to the connecting blocks 9. The connecting tube 10 is a corrugated pipe. The end of the second application tube 6 near the nozzle 7 is fixed with a second boss 25. The top of the second boss 25 is fixed with an arc-shaped buckle 26.

[0022] A fixing component for fixing the sleeve 18 is installed at the bottom of the first application tube 5 near the second application tube 6. The fixing component includes a protrusion 11 fixed to the outer surface of the first application tube 5. The protrusion 11 is located at the end of the first application tube 5 near the second application tube 6. A slot 12 is opened on one side of the protrusion 11. An insert 13 is fixed on the outer surface of the sleeve 18 and is inserted into the slot 12. The insert 13 has an L-shaped structure. Two insertion holes 14 are opened on the side of the slot 12 away from the sleeve 18. Insert rods 15 are installed on both sides of the protrusion 11 away from the first application tube 5. One end of the insert rod 15 passes through the protrusion 11 and is inserted into the insertion hole 14. A control block 16 is fixed to the other end of the insert rod 15. A tension spring 17 is sleeved on the surface of the insert rod 15. One end of the tension spring 17 is fixed to the control block 16, and the other end of the tension spring 17 is fixed to the protrusion 11.

[0023] The first application tube 5 and the second application tube 6 are equipped with anti-detachment components at their close ends. The anti-detachment components include a first boss 19 fixed on both sides of the outer surface of the first application tube 5 and the second application tube 6, a positioning post 20 fixed on the other side of the first boss 19, a limit block 21 fixed at the other end of the positioning post 20, and limit plates 22 provided on both sides of the sleeve 18. The end of the limit plate 22 near the second application tube 6 is provided with a through hole 23 that is rotatably connected to the positioning post 20, and the end of the limit plate 22 near the first application tube 5 is provided with a through groove 24 that is slidably connected to the positioning post 20.

[0024] Specifically: The first application tube 5 and the second application tube 6 are connected via the threaded connection of the mounting groove 8 and the connecting block 9 in the connecting assembly, and in conjunction with the connecting pipe 10. When the first application tube 5 and the second application tube 6 need to be used after connection, the sleeve 18 is inserted into the interior of the connecting groove 27. At the same time, one end of the insert block 13 in the fixing assembly is inserted into the interior of the slot 12. Then, the control block 16 controls the insert rod 15 to be inserted into the interior of the insertion hole 14 to fix the position of the insert block 13. After fixing, the tension generated by the tension spring 17... Force is applied to prevent the insertion rod 15 from disengaging from the insertion hole 14. Through the cooperation of the connecting component and the fixing component, the first application tube 5 and the second application tube 6 are connected as a whole for application. When it is necessary to reduce the length of the pipeline, the control block 16 drives the insertion rod 15 to disengage from the insertion hole 14, releasing the limit on the insertion block 13 and causing the insertion block 13 to disengage from the slot 12. At the same time, the sleeve 18 disengages from the tension spring 17, releasing the limit between the first application tube 5 and the second application tube 6. Then, the second application tube is folded. 6. The first application tube 5 and the second application tube 6 are combined. The connecting tube 10 at the connection point has good ductility due to the characteristics of the corrugated pipe, which can prevent breakage during folding. With the setting of the arc-shaped buckle 26, when the second application tube 6 is folded, it can be connected and fixed to the first application tube 5 through the arc-shaped buckle 26. When the first application tube 5 and the second application tube 6 are disconnected and rotated, they are rotatably connected to the positioning post 20 through the through hole 23 in the limiting plate 22. The other end of the limiting plate 22 is slidably connected to the positioning post 20 through the through groove 24, which can avoid motion interference when the second application tube 6 is folded. By folding the second application tube 6, the overall length of the first application tube 5 and the second application tube 6 after connection is greatly reduced, which can effectively reduce the space occupied during daily storage and transportation, making the first application tube 5 and the second application tube 6 easier to place. At the same time, it can reduce the probability of damage due to bumps and avoid damage to the device affecting the normal use of the equipment.

[0025] Working principle: The first application tube 5 and the second application tube 6 are connected by the threaded connection of the mounting groove 8 and the connecting block 9 in the connecting assembly, and the connecting tube 10. When the first application tube 5 and the second application tube 6 need to be used, the sleeve 18 is inserted into the interior of the connecting groove 27. At the same time, one end of the insert block 13 in the fixing assembly is inserted into the interior of the slot 12. Then, the control block 16 controls the insertion rod 15 to be inserted into the interior of the insertion hole 14, fixing the position of the insert block 13. After fixing, the tension generated by the tension spring 17 can prevent the insertion rod 15 from disengaging from the interior of the insertion hole 14. Through the cooperation of the connecting assembly and the fixing assembly, the first application tube 5 and the second application tube 6 are connected into a whole for application. When it is necessary to reduce the length of the pipeline, the control block 16 drives the insertion rod 15 to disengage from the interior of the insertion hole 14, releasing the limitation on the insert block 13, and allowing the insertion rod 15 to be inserted into the insertion hole 14. Block 13 disengages from the slot 12, and sleeve 18 disengages from the tension spring 17, releasing the restriction between the first application tube 5 and the second application tube 6. Then, by folding the second application tube 6, the first application tube 5 and the second application tube 6 are merged. The connecting tube 10 at the connection point has good ductility due to the characteristics of the corrugated pipe, which can prevent breakage during folding. With the setting of the arc-shaped buckle 26, when the second application tube 6 is folded, the second application tube 6 can be connected and fixed to the first application tube 5 through the arc-shaped buckle 26. When the first application tube 5 and the second application tube 6 are disconnected and rotated, they are rotatably connected to the positioning post 20 through the through hole 23 in the limiting plate 22. The other end of the limiting plate 22 is slidably connected to the positioning post 20 through the through groove 24, which can avoid the problem of motion interference when folding the second application tube 6.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
