The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides an anti-clogging seedling water and fertilizer mixing spraying device, including a main pipe 1. The main pipe 1 is made of PVC or stainless steel, which has good corrosion resistance and ensures that it is not easily damaged after contact with the water and fertilizer mixture.

[0025] The main pipe 1 has connectors 4 fixedly installed on both sides by welding or injection molding. The connectors 4 have external threads on the outside for connecting to external liquid supply pipes. The main pipe 1 and connectors 4 are internally connected to realize the input of water-fertilizer mixture. The nozzle pipe 21 is fixedly installed at the bottom of the main pipe 1. The nozzle pipe 21 is set perpendicular to the main pipe 1 and the two are internally connected. The main pipe 1, nozzle pipe 21 and connectors 4 form a three-way joint structure, in which the main pipe 1 is the main pipe and the nozzle pipe 21 is the branch pipe.

[0026] The nozzle assembly 2 includes a nozzle tube 21 and a spray head 22. The spray head 22 has a conical structure with multiple spray holes at the bottom to ensure uniform spraying of the water-fertilizer mixture. An external threaded cylinder 24 is welded to the top of the spray head 22 and communicates with the interior of the spray head 22. An internal threaded hole 26, adapted to the external threaded cylinder 24, is formed on the inner wall of the nozzle tube 21. The external threaded cylinder 24 is screwed into the internal threaded hole 26, allowing for detachable installation of the spray head 22 for easy cleaning or replacement.

[0027] The inner wall of the mounting external threaded cylinder 24 has the same diameter as the inner wall of the nozzle pipe 21 to avoid the formation of a stepped structure that would cause impurities to accumulate and clog. A sealing gasket 25 is fixedly installed on the top of the mounting external threaded cylinder 24 by adhesive bonding. The sealing gasket 25 is made of rubber. When the mounting external threaded cylinder 24 is fully screwed to the bottom of the internal threaded hole 26, the sealing gasket 25 fits tightly against the connection between the top of the mounting external threaded cylinder 24 and the nozzle pipe 21 to achieve a seal and prevent water and fertilizer leakage.

[0028] A dispersing net 23 is fixedly installed at the bottom of the nozzle pipe 21 by a clip. The dispersing net 23 is made of stainless steel mesh, and the mesh size can be selected according to the needs of seedling cultivation. It can disperse the water-fertilizer mixture into fine droplets and intercept large particles of impurities. The dispersing net 23 is located below the external threaded cylinder 24 and is connected to the inside of the spray head 22 to ensure that the dispersed mixture is sprayed out smoothly.

[0029] A cleaning assembly 3 is fixedly installed on the top of the main body pipe 1. The cleaning assembly 3 includes a top block 31, which is fixedly installed on the top of the main body pipe 1 by welding or bolts, and is located directly above the nozzle pipe 21 and coaxially arranged with the nozzle pipe 21. An internal groove 35 is formed inside the top block 31. The internal groove 35 is a cylindrical groove, and a rubber block 36 is slidably connected inside it. The rubber block 36 is cylindrical and made of wear-resistant and corrosion-resistant rubber material.

[0030] The internal groove 35 is connected to the inside of the main tube 1 through a reserved through hole. The rubber block 36 is located at the connection point, and an arc-shaped groove is opened at its bottom. The arc of the groove is completely fitted with the inner wall of the main tube 1, ensuring that the rubber block 36 does not affect the normal flow of the water-fertilizer mixture inside the main tube 1 when not being cleaned. At the same time, the sealing properties of the rubber material prevent the water-fertilizer mixture from seeping into the internal groove 35.

[0031] A fixing post 32 is welded to the top of the top block 31. The fixing post 32 is a cylindrical structure, and a screw rod 33 is threaded through it and connected to the inside of the top wall of the top block 31. The bottom of the screw rod 33 is fixed to the top of the rubber block 36 by adhesive or thread. A knob 34 is welded to the top of the screw rod 33. The knob 34 has anti-slip texture on the outside for easy rotation by the operator. The cross-section of the rubber block 36 and the cross-section of the internal groove 35 are both circular and the same as the inner diameter of the nozzle pipe 21, ensuring that the rubber block 36 can be completely embedded inside the nozzle pipe 21 when it descends, so as to thoroughly clean the pipe wall and the dispersion net 23.

[0032] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0033] Working principle: Equipment installation: Connect the connectors 4 on both sides of the main pipe 1 to the external liquid supply pipe to ensure a firm connection; check the installation status of the spray head 22, and fix the spray head 22 to the bottom of the spray head pipe 21 by screwing the external threaded cylinder 24 and the internal threaded hole 26, ensuring that the sealing gasket 25 fits tightly and there is no leakage.

[0034] Normal spraying: Upon activation of the external liquid supply system, the water-fertilizer mixture enters the main tube 1 through connector 4, flows along the main tube 1 to the nozzle tube 21, is dispersed into fine droplets by the dispersing net 23, and then evenly sprayed onto the seedling area through the spray holes of the nozzle 22, providing nutrients and water to the seedlings. During this process, the arc-shaped groove at the bottom of the rubber block 36 fits snugly against the inner wall of the main tube 1, without affecting the normal flow of the mixture.

[0035] Clog Clearing: When uneven spraying or reduced flow is observed at the spray head 22, it indicates blockage or impurities on the inner wall of the dispersion net 23 or the spray head tube 21. In this case, there is no need to shut off the liquid supply system. Simply turn the knob 34 to rotate the screw 33. Since the screw 33 is screwed into the fixed column 32 and the top block 31, it will drive the rubber block 36 to slide downwards along the internal groove 35 and embed itself inside the spray head tube 21. As the rubber block 36 descends, its outer side makes close contact with the inner wall of the spray head tube 21, scraping and cleaning the adhering impurities on the tube wall; simultaneously, it squeezes the blockage particles on the dispersion net 23, causing them to be discharged through the spray head 22 with the water flow, achieving rapid cleaning. After cleaning, turn the knob 34 in the opposite direction to return the rubber block 36 to its original position in the internal groove 35, restoring normal spraying.

[0036] Deep maintenance: If the blockage is severe, the spray head 22 can be unscrewed and the spray head 22, the external threaded cylinder 24 and the dispersion net 23 can be thoroughly cleaned or replaced. After maintenance, the spray head 22 can be re-screwed and installed.

[0037] Equipment storage: After the operation is completed, turn off the liquid supply system, drain the residual water and fertilizer mixture inside the equipment, and clean the surface of the equipment to avoid impurities causing blockage during the next use.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
