[0002] In the production of water-soluble fertilizers, multiple raw materials typically need to be mixed, dissolved, and reacted to form a fertilizer solution with specific nutrient components. Stepwise dissolution technology is a method that dissolves fertilizer raw materials in stages. In the production of water-soluble fertilizers, stepwise dissolution technology ensures that all raw materials are fully dissolved and avoids fertilizer quality degradation due to incomplete dissolution.

[0003] By combining stepwise dissolution technology with gradient spraying technology, a highly efficient water-soluble fertilizer conversion device can be designed. This device enables the staged dissolution and precise spraying of fertilizer raw materials, thereby improving fertilizer dissolution efficiency, mixing uniformity, and utilization rate. Furthermore, the device can be flexibly adjusted according to crop growth needs and soil conditions to meet the requirements of different agricultural production scenarios.

[0004] When fertilizers are not mixed sufficiently during dissolution and the spraying intensity is not adjustable, problems such as uneven distribution of nutrients in the solution and uneven spraying occur. In view of this, a water-soluble fertilizer conversion device that combines step dissolution and gradient spraying is provided. Utility Model Content

[0005] The main purpose of this invention is to provide a water-soluble fertilizer conversion device that combines stepwise dissolution and gradient spraying, so as to solve the problems of uneven distribution of nutrients in the solution and uneven spraying when the fertilizer is not fully mixed during the dissolution process and the spraying intensity is not adjustable, as mentioned in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a water-soluble fertilizer conversion device combining step dissolution and gradient spraying is provided, comprising a first dissolution chamber, a second dissolution chamber fixedly disposed at the bottom of the first dissolution chamber, a plurality of support legs for support disposed at the bottom of the second dissolution chamber, a rotating shaft rotatably disposed in both the first and second dissolution chambers, a plurality of stirring rods disposed on each rotating shaft, a plurality of guide plates fixedly disposed on each stirring rod, and a spraying section with adjustable spraying intensity fixedly connected to one side of both the first and second dissolution chambers.

[0007] Furthermore, the first dissolving chamber includes a bottom plate, which is conical in shape with a higher center and a lower center near the edges. A through hole is provided in the center of the bottom plate, and a conduit is fixedly installed on the bottom plate. The conduit connects the first dissolving chamber and the second dissolving chamber, and a solenoid valve is provided at the lower end of the conduit.

[0008] Furthermore, a top cover is fixedly installed on the top of the first dissolution chamber, and a column hole is opened through the center of the top cover. A power source is fixedly installed at the top of the top cover concentric with the column hole.

[0009] Furthermore, a first rotating shaft is rotatably provided in the first dissolving chamber, with one end of the first rotating shaft rotatably installed in the through hole and the other end of the first rotating shaft rotatably installed in the column hole. Similarly, a second rotating shaft is rotatably provided in the second dissolving chamber.

[0010] Furthermore, the first rotating shaft has several grooves, one end of the stirring rod is inserted into the groove, and a screw is threaded through the stirring rod and onto the side wall of the first rotating shaft.

[0011] Furthermore, a screw hole is provided at the bottom of the first rotating shaft, and a fixing block is fixedly provided at the top of the second rotating shaft, with the fixing block threaded into the screw hole.

[0012] Furthermore, the guide plate is inclined at different angles on the stirring rod, and two symmetrically arranged fixing plates are fixed at the other end of the stirring rod, the fixing plates being trapezoidal.

[0013] Furthermore, the spraying section includes a connecting pipe that penetrates the side wall of the dissolving chamber. A water pump is connected to the water inlet end of the connecting pipe. The connecting pipe has two water outlets, each with several sets of connecting ports of different diameters. Each water outlet end of the connecting pipe is threaded with a nozzle, and the water inlet end of the nozzle has symmetrically arranged liquid outlets.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this water-soluble fertilizer conversion device that combines step dissolution and gradient spraying, a guide plate and a fixing plate are installed on the rotating stirring rod. By tilting the guide plate, a more complex flow field can be generated, which helps the fertilizer solution to be more fully mixed in the dissolution chamber. The guide plate can also reduce eddies and dead corners during the stirring process, ensuring that the fertilizer solution can be evenly distributed, thereby improving the stirring efficiency. The trapezoidal fixed plate can better stir the fertilizer at the bottom of the dissolution chamber, ensuring the uniform dissolution of the fertilizer.

[0016] 2. In this water-soluble fertilizer conversion device that combines step dissolution and gradient spraying, a conical base plate with a high center and low edges is set up. This design allows the fertilizer solution to flow along the inclined surface of the base plate towards the central area of ​​the conduit due to gravity during the dissolution process, ensuring that the fertilizer solution can be collected and guided more effectively.

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Please see Figures 1-10 As shown, the purpose of this embodiment is to provide a water-soluble fertilizer conversion device that combines step dissolution and gradient spraying, including a first dissolution chamber 1, a second dissolution chamber 2 fixedly disposed at the bottom of the first dissolution chamber 1, a plurality of support legs 23 for support disposed at the bottom of the second dissolution chamber 2, a rotating shaft rotatably disposed in both the first dissolution chamber 1 and the second dissolution chamber 2, a plurality of stirring rods 111 disposed on the rotating shaft, a plurality of guide plates 115 fixedly disposed on the stirring rods 111, and a spray section with adjustable spray intensity fixedly connected to one side of both the first dissolution chamber 1 and the second dissolution chamber 2.

[0032] The first dissolving chamber 1 includes a base plate 12, which is conical in shape, higher in the middle and lower near the edges. A through hole 121 is formed in the center of the base plate 12. A conduit 14 is also fixedly mounted on the base plate 12, connecting the first dissolving chamber 1 and the second dissolving chamber 2. A solenoid valve is installed at the lower end of the conduit 14 to control the flow of fertilizer solution. When the fertilizer solution in the first dissolving chamber 1 reaches a predetermined concentration or degree of dissolution, the solenoid valve opens, allowing the fertilizer solution to flow into the second dissolving chamber 2. The surface of the base plate 12 around the conduit 14 is inclined towards the center of the conduit 14, which helps the fertilizer solution to gather towards the center during the dissolution process, facilitating its subsequent flow into the second dissolving chamber 2 through the conduit 14.

[0033] A top cover 13 is fixedly installed on the top of the first dissolving chamber 1. A column hole 131 is opened through the center of the top cover 13, and a power source 4 is fixedly installed at the top of the top cover 13 and the column hole 131 concentrically. The power source 4 is preferably an electric motor. The top cover 13 is inserted and installed on the top of the first dissolving chamber 1. The top cover 13 is fixed on the top of the first dissolving chamber 1 by bolts to form a reliable seal and prevent leakage of dissolved substances during the dissolving process.

[0034] The second dissolving chamber 2 has a liquid injection port 22 through the side wall. The liquid injection port 22 is inclined inward, which helps the liquid to flow downward along the slope when the substance for dissolving fertilizer is injected, and to be more evenly distributed in the second dissolving chamber 2, so as to ensure that it can be further fully dissolved with the existing fertilizer. The liquid injection port 22 is equipped with a sealing plug to keep it sealed when the liquid injection port 22 is not in use.

[0035] A first rotating shaft 11 is rotatably installed in the first dissolving chamber 1. One end of the first rotating shaft 11 is rotatably installed in the through hole 121, and the top end of the first rotating shaft 11 is fixedly connected to the motor output shaft. The other end of the first rotating shaft 11 is rotatably installed in the column hole 131. When the motor starts, its output shaft will drive the first rotating shaft 11 to rotate together. Similarly, a second rotating shaft 21 is rotatably installed in the second dissolving chamber 2. The second rotating shaft 21 is rotatably installed on the lower plate of the second dissolving chamber 2.

[0036] The first rotating shaft 11 has several grooves 112. One end of the stirring rod 111 is inserted into a groove 112, and a screw 113 is threaded through the stirring rod 111 and onto the side wall of the first rotating shaft 11. The end of the screw 113 can be pressed against the stirring rod 111. Depending on the amount and concentration of fertilizer to be stirred and dissolved, the operator can manually adjust the tilt angle of the stirring rod 111. The tilt angle of the stirring rod 111 only needs to be adjusted beforehand, and then it can be fixed by pressing the screw 113 against the stirring rod 111, thus allowing for angle adjustment. Generally, when the amount of fertilizer is large or the concentration is high, the tilt angle of the stirring rod 111 needs to be increased to better mix the fertilizer solution; conversely, the tilt angle of the stirring rod 111 can be appropriately reduced. After the tilt angle of the stirring rod 111 is adjusted to the required position, it needs to be fixed to the side wall of the first rotating shaft 11 with screws 113. The screws 113 penetrate the side wall of the stirring rod 111 and are threadedly connected to the side wall of the first rotating shaft 11, thereby providing sufficient fastening force to prevent the stirring rod 111 from loosening or falling off during rotation.

[0037] The first rotating shaft 11 has a screw hole 114 at its bottom, and the second rotating shaft 21 has a fixing block 211 fixedly installed at its top. The fixing block 211 is threaded into the screw hole 114, and the tightening direction of the fixing block 211 is opposite to the rotation direction of the first rotating shaft 11. When the first rotating shaft 11 rotates during the stirring process, since the fixing block 211 has been pre-tightened into the screw hole 114 and its threaded connection provides sufficient friction, it will not fall off during the stirring process. This ensures that the connection between the first rotating shaft 11 and the second rotating shaft 21 will not loosen or fail even when rotating at high speed or under great resistance.

[0038] The guide plate 115 is a plate-like structure mounted on the stirring rod 111. Its main function is to guide the flow of fertilizer solution within the dissolving chamber, thereby improving stirring efficiency and dissolving effect. The guide plate 115 is inclined at different angles on the stirring rod 111. By tilting the guide plate 115, a more complex flow field can be generated, which helps the fertilizer solution to mix more thoroughly within the dissolving chamber. At the same time, the guide plate 115 can also reduce eddies and dead zones during stirring, ensuring that the fertilizer solution is evenly distributed, thereby improving stirring efficiency and dissolving effect.

[0039] Furthermore, two symmetrically arranged fixing plates 116 are fixedly installed at the other end of the stirring rod 111. The fixing plates 116 are trapezoidal, with the lower fixing plate 116 having a larger diameter. The trapezoidal structure of the fixing plate 116 not only provides a larger support area and enhances the stability of the stirring rod 111, but also extends the service life of the stirring rod 111 by dispersing stress and torque. At the same time, the larger diameter of the lower fixing plate 116 can better stir the fertilizer at the bottom of the dissolving chamber, ensuring the uniform dissolution of the fertilizer. The stirring rod 111 on the second rotating shaft 21 has the same structure, which means that the stirring rod 111 on the second rotating shaft 21 is also equipped with an inclined guide plate 115 and a trapezoidal fixing plate 116, ensuring that the entire stirring system generates a more uniform flow field during the stirring process, further improving the stirring efficiency and dissolution effect.

[0040] The spray unit includes a connecting pipe 3 that penetrates the side wall of the dissolving chamber. A water pump 31 is connected to the inlet end of the connecting pipe 3. The connecting pipe 3 has two outlet ends, each with several sets of connecting ports 33 of different diameters. Each outlet end of the connecting pipe 3 is threaded with a nozzle 32. This connection method is not only firm and reliable, but also easy to disassemble and replace. The inlet end of the nozzle 32 has a screw groove 321, and the outlet end of the connecting pipe 3 is threaded into the screw groove 321. The inlet end of the nozzle 32 has symmetrically arranged liquid outlets 322. The connecting port 33 with the largest diameter has the same diameter as the liquid outlet 322. By rotating the nozzle 32, the connecting ports 33 of different diameters are aligned with the liquid outlets 322 and are concentric, thereby adjusting the spray intensity.

[0041] When the water pump 31 starts, it draws the dissolved fertilizer from the dissolving chamber and delivers it to the nozzle 32 through the connecting pipe 3. During delivery, the water passes through connection ports 33 with different orifices on the connecting pipe 3. By rotating the nozzle 32, the orifice size of the connection port 33 aligned with the liquid outlet 322 can be selected. The larger the orifice size, the greater the spray intensity; the smaller the orifice size, the smaller the spray intensity. The spray intensity is mainly adjusted by rotating the nozzle 32. During rotation, attention should be paid to the alignment of the liquid outlet 322 and the connection port 33 to ensure they are concentric. This ensures that water or fertilizer is sprayed evenly from the nozzle 32, achieving the best spraying effect. To more accurately adjust the spray intensity, corresponding marks or scales are set on the nozzle 32 to clearly indicate the corresponding orifice size of the connection port 33.

[0042] In practical use, as needed, the fixing block 211 is screwed into the screw hole 114 of the first rotating shaft 11. The height of the stirring rod 111 in the first dissolving chamber 1 and the second dissolving chamber 2 is adjusted by rotation. The position of the stirring rod 111 in the groove 112 is fixed by tightening the screw 113. The fertilizer to be dissolved is injected into the first dissolving chamber 1. The top cover 13 is inserted into the first dissolving chamber 1 and fixed by bolts. The power source 4 drives the first rotating shaft 11 to rotate and stir, thereby driving the second rotating shaft 21 to rotate and stir. The rotation direction of the second rotating shaft 21 is opposite to the stirring direction. When the first dissolving chamber... When the fertilizer solution in chamber 1 reaches the predetermined concentration or degree of dissolution, the solenoid valve is opened, allowing the fertilizer solution to flow into the second dissolution chamber 2 through the conduit 14 for further dissolution. The fertilizer-dissolving substance is injected into the second dissolution chamber 2 through the injection port 22. When the fertilizer solution in the second dissolution chamber 2 also reaches the predetermined concentration, the motor is turned off. According to the spray intensity requirements, the nozzle 32 is threaded onto the outlet end of the connecting pipe 3. By rotating the nozzle 32, a suitable orifice size of the connecting port 33 is selected to be aligned with the outlet 322. The fertilizer solution in the two dissolution chambers is pumped to the connecting pipe 3 by the water pump 31 and sprayed onto the crops through the nozzle 32.
