[0002] The forestry industry includes multiple fields such as timber processing, economic forest planting, and under-forest economy. The occurrence of pests and diseases can have a serious impact on these industries. Effective prevention and control of pests and diseases is conducive to ensuring the stable development of the forestry industry and creating good economic benefits for forest farmers and forestry enterprises. In the process of preventing and controlling pests and diseases, spray nozzles are used to spray pesticides on trees.

[0003] Currently, the openings of existing spray nozzles are always open. In forestry pest and disease control, the working environment is usually quite complex, with a large amount of dust, soil particles, plant debris, and other impurities present. When the nozzle is not in use, these impurities can easily enter the nozzle, causing blockage of the nozzle orifice. This results in uneven spraying, reduced spray volume, or even failure to spray normally, affecting subsequent use and work efficiency. To address these issues, we propose a new spray nozzle for forestry pest and disease control. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A spray nozzle for controlling forest pests and diseases includes a nozzle body 1. One end of the nozzle body 1 is connected to a spray bar 6, and the other end of the nozzle body 1 is connected to a fixed plate 2. The center of the fixed plate 2 is connected to a rotating plate 3 via a bearing. The fixed plate 2 and the rotating plate 3 are respectively provided with strip grooves inside. The nozzle body 1 is provided with a rectangular groove inside. A spring 8 is connected to the inner wall of the rectangular groove. The other end of the spring 8 is connected to a rectangular plate 7. A push rod 9 is connected to one side of the rectangular plate 7 and extends to the outside of the rectangular groove. A limit block 10 is connected to the other side of the rectangular plate 7. The rotating plate 3 is provided with slots that are adapted to the limit block 10 inside. By setting multiple sets of slots, it is convenient for the staff to limit the rotating plate 3 when it is rotated to a suitable position.

[0023] Furthermore, refer to Figure 3 It can be seen that the inner side of the rotating plate 3 is connected to the connecting ring 4, and the inside of the nozzle body 1 is provided with an annular groove that matches the connecting ring 4. Through the setting of the annular groove and the connecting ring 4, the reliability of the rotating plate 3 during the rotation process can be effectively guaranteed.

[0024] Furthermore, refer to Figure 3 It can be seen that the inner wall of the rectangular groove is connected to a fixing rod 11, and the inside of the rectangular plate 7 is provided with a hole that matches the fixing rod 11. When the worker pushes the push rod 9, the rectangular plate 7 connected to its inner side can be subjected to force and slide along the outer surface of the fixing rod 11, thereby ensuring the reliability of the movement of the rectangular plate 7 and the limiting block 10.

[0025] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the side of the rotating plate 3 is connected to a rectangular piece 5, and the rectangular pieces 5 are distributed in a ring array on the outer surface of the rotating plate 3. In use, the arrangement of multiple sets of rectangular pieces 5 makes it easy for the operator to rotate the rotating plate 3.

[0026] Furthermore, refer to Figure 4 It can be seen that a filter screen 12 is provided on the side of the rotating plate 3 away from the fixed plate 2, and a fixed piece 13 is connected to the edge of the filter screen 12. In use, the filter screen 12 can block the clumping of the drug, thereby effectively ensuring the uniformity of the drug spraying process.

[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the rotating plate 3 is symmetrically connected with the insertion rod 14 on its side. The fixed plate 13 has an insertion groove inside that matches the insertion rod 14. The insertion rod 14 is fitted with a nut on its outer side. Through the cooperation of the insertion rod 14 and the nut, the filter screen 12 can be easily removed from the side of the rotating plate 3 by the staff, so that the staff can pour out the impurities from the strip groove inside the fixed plate 2 and the rotating plate 3.

[0028] Furthermore, refer to Figure 3 It can be seen that there are two sets of springs 8 inside the rectangular groove, and the two sets of springs 8 are symmetrically distributed about the central axis of the rectangular plate 7. Through the elastic characteristics of the springs 8 themselves, the normal rebound of the limit block 10 can be effectively guaranteed.

[0029] Working Principle: When using this utility model, the operator can first connect the delivery pipe to the tail end interface of the spray bar 6. Then, the operator can hold the spray bar 6 and aim the nozzle body 1 at the trees to spray the pesticide to achieve the purpose of pest and disease control. After the spraying work is completed, the operator only needs to push the push rod 9 to move the rectangular plate 7 and the limiting block 10, so that the limiting block 10 can be pulled out from the slot opened inside the rotating plate 3. Then, the operator can rotate the rotating plate 3 to make the strip groove opened inside it misalign with the strip groove opened inside the fixed plate 2. At this time, the operator can stop pushing the push rod 9, so that the limiting block 10 is locked into another set of slots inside the rotating plate 3 by the elastic force of the spring 8, so as to seal the opening of the nozzle body 1, thereby preventing foreign objects from entering the interior of the nozzle body 1 and effectively ensuring the service life of the nozzle body 1. The above is the complete working principle of this utility model.
