[0002] With the development of technology, agricultural spray guns are also constantly improving. For example, the application of intelligent management and precision spraying technology makes agricultural production more efficient and environmentally friendly. In the future, agricultural spray guns will play an even more important role in modern agriculture, promoting the intelligent and precision development of agriculture. Currently, with quick-connect spray guns, the connection point rotates due to the water flow when spraying water, causing the nozzle to rotate and making it difficult to control the position of the sprayed pesticide or water flow; while with ordinary spray guns, changing the nozzle according to the working conditions is troublesome.

[0003] Therefore, in order to address the problem that in the existing quick-connect spray gun, the connection point rotates due to the water flow when spraying water, which in turn causes the nozzle to rotate and makes it difficult to control the position of the sprayed medicine or water flow, a quick-connect spray gun is needed.

[0027] Example 1:

[0028] A quick-connect spray gun includes a branch pipe 2, a quick-connect plug 3, and a gun body;

[0029] The aforementioned branch pipe 2 is equipped with a nozzle 1;

[0030] One end of the quick-connect plug 3 is fixed to the branch pipe 2, and the other end of the quick-connect plug 3 is inserted into the gun body. A keyway mechanism is provided between the gun body and the quick-connect plug 3 to lock the quick-connect plug 3 in the circumferential direction.

[0031] In the above structure, a keyway mechanism is provided between the quick-connect plug 3 and the gun body, so that the quick-connect plug 3 will not rotate in the circumferential direction and the quick-connect plug 3 is axially engaged; when the quick-connect spray gun is working, the nozzle 1 will not rotate, the sprayed medicine or water is more concentrated, and it is more convenient to replace the nozzle 1 and the bracket according to the actual working conditions.

[0032] The branch pipe 2 is provided with multiple nozzles, and each nozzle is threadedly connected to a nozzle 1. The nozzle 1 is threadedly connected to the nozzle orifice, making it easy to disassemble and replace the nozzle 1.

[0033] The aforementioned gun body includes a gun body 8 and a connecting tube 7. The connecting tube 7 is integrally connected to one end of the aforementioned gun body 8, and the aforementioned quick-connect plug 3 is inserted into the aforementioned connecting tube 7.

[0034] The aforementioned keyway mechanism includes a limiting key 4 and a limiting groove 13. The quick-connect insert 3 has a ring of the aforementioned limiting key 4 in its center, and the inner wall of the connecting pipe 7 has a ring of the aforementioned limiting groove 13. When the quick-connect insert 3 and the connecting pipe 7 are inserted together, the limiting key 4 engages with the corresponding limiting groove 13. The interlocking of the limiting key 4 on the quick-connect insert 3 and the limiting groove 13 on the connecting pipe 7 forms a keyed connection, achieving circumferential positioning of the quick-connect insert 3 and the gun body. Furthermore, the sealing ring 6 ensures airtightness.

[0035] The aforementioned quick-connect plug 3 is also provided with a first card platform 5, which is located below the aforementioned limit key 4, and the bottom of the aforementioned quick-connect plug is provided with a sealing ring 6.

[0036] The aforementioned connecting pipe 7 is a hollow pipe. Connecting pipe 7 is used to transport medicine and water.

[0037] The connecting pipe 7 includes an outer pipe 10 and an inner pipe 11. The outer pipe 10 is slidably sleeved on the inner pipe 11. The bottom of the inner pipe 11 is provided with a first limiting frustum 12, and the inner wall of the top of the outer pipe 10 is provided with a second limiting frustum 14. The first limiting frustum 12 and the second limiting frustum 14 form a cavity to accommodate the compression spring 16. A ring of retaining beads 15 is embedded in the inner wall of the inner pipe 11. The retaining beads 15 are engaged with the first retaining platform 5, and the limiting groove 13 is located above the retaining beads 15. When the outer pipe 10 is pulled down, the retaining beads 15 on the inner wall move towards the outer pipe 10, and the engagement between the retaining beads 15 and the first retaining platform 5 is disengaged, thereby removing the quick-connect insert 3 from the connecting pipe 7. The first limiting frustum 12 serves to hold and limit the spring.

[0038] The aforementioned gun body 8 is equipped with a switch. Specifically, liquid enters the aforementioned connecting pipe 7 through the tail end of the gun body 8, and the switch is used to control the flow of liquid.

[0039] Specifically, by setting a limit key 4 on the quick-connect plug 3 and a limit groove 13 on the connecting pipe 7, the quick-connect plug 3 and the gun body are limited in the circumferential direction, preventing the quick-connect plug 3 from rotating due to water flow, thus ensuring that the liquid spray is more concentrated and the direction is controllable; and by the axial snap-fit ​​between the quick-connect plug 3 and the connecting pipe 7, the convenience of replacing and disassembling different models of nozzles 1 is ensured.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
