[0035] A water inlet is also provided on the upper portion of the outer surface of the mixing barrel 1 for injecting water thereinto. This structure is a conventional structure and will not be marked or described in detail in the present invention.

[0036] It should be noted that the above-mentioned drip irrigation pump 2 is a conventional drip irrigation water pump, which has been widely used in the prior art. In the present invention, it is only used to realize the function of extracting the mixed water and fertilizer in the mixing barrel 1 for drip irrigation, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0037] Further, in order to achieve the processing of solid fertilizers, see Figure 3 and Figure 4The solid fertilizer processing structure 5 includes a driving shaft 51 which is connected to the output end of the driving motor 7 through a telescopic coupling, a grinding driving assembly 53 is fixedly connected to the middle of the outer surface of the driving shaft 51, and a revolution driving assembly 52 is provided on the upper part of the outer surface of the driving shaft 51 and the top wall of the inner cavity of the mixing barrel 1, a screen 56 which is rotatably connected to the outer surface of the driving shaft 51 is fixedly connected to the middle of the inner cavity of the mixing barrel 1, grinding rollers 54 are symmetrically arranged on the outer surface of the grinding driving assembly 53, and screening scrapers 55 are symmetrically arranged on the outer surface of the grinding driving assembly 53, and a conical plate 57 is fixedly connected to the position below the screen 56 on the inner surface of the mixing barrel 1.

[0038] During the operation of this embodiment, the drive shaft 51 is connected to the output end of the drive motor 7, and the drive motor 7 drives the drive shaft 51 to rotate, thereby driving the grinding drive assembly 53, the grinding roller 54, and the screening scraper 55 to revolve above the screen 56, grinding and crushing the solid fertilizer particles input through the feed port 4, breaking up the agglomerated particles in the solid fertilizer, improving its fusion efficiency with water, and then increasing the fertilizer ratio in unit water and fertilizer, improving the fertilization efficiency and crop absorption efficiency, reducing waste, and avoiding uneven distribution of fertility.

[0039] Further, for mixing solid fertilizer with water, see Figure 3 The water-fertilizer mixing structure 6 includes an air pump 61 fixedly connected to the upper end, an air sliding ring 65 sleeved on the outer surface of the driving shaft 51 and rotatably connected to the driving shaft 51 is fixedly connected to the output end of the air pump 61, a gear ring 62 is fixedly connected to the portion of the inner surface of the mixing barrel 1 below the conical plate 57, a limiting ring 67 is fixedly connected to the portion of the inner surface of the mixing barrel 1 below the gear ring 62, and a stirring assembly 63 transmission-connected to the driving shaft 51 is jointly provided at one end of the limiting ring 67 and the gear ring 62 close to each other, and a connecting rod 64 is provided at the lower end of the stirring assembly 63.

[0040] The fertilizer crushed into particles or powder will fall into the lower part of the inner cavity of the mixing barrel 1 through the screen 56, and the driving shaft 51 will drive the stirring assembly 63 to rotate between the gear ring 62 and the limit ring 67, so that the stirring assembly 63 and the gear ring 62 are used to stir the mixture of water and solid fertilizer, so as to promote the dissolution of solid fertilizer to form water fertilizer. Furthermore, stirring can improve the uniformity of the distribution of nutrients in the water and avoid uneven distribution in the subsequent fertilization process.

[0041] Embodiment 2. On the basis of Embodiment 1, this embodiment drives the installation box 531 to rotate through the drive shaft 51, and through the limiting effect of the revolution drive assembly 52 on the first bevel gear 532, it prompts the second bevel gear 533 meshed with the first bevel gear 532 to rotate self while revolving following the installation box 531. Thus, it drives the grinding roller 54 to rotate self while revolving above the screen 56, and grinds and crushes the large particle agglomerated fertilizer staying above the screen 56.

[0042] Furthermore, by using the cooperation of the corrugated groove 571 and the limiting wheel 572, it drives the drive shaft 51 to move up and down synchronously during rotation, and further drives the grinding drive assembly 53 and the grinding roller 54 to move up and down, so as to further realize knocking the agglomerated fertilizer particles during grinding, improve the processing efficiency of solid fertilizer, and provide a solid foundation for subsequent water-fertilizer mixing.

[0043] Specifically, to drive the grinding roller 54 to revolve around the axis of the drive shaft 51 and knock and crush the solid fertilizer, refer to Figure 5 , the grinding drive assembly 53 includes an installation box 531 fixedly connected to the outer surface of the drive shaft 51. The second bevel gears 533 are symmetrically and rotatably connected to the left and right inner surfaces of the installation box 531. The first bevel gear 532 meshing with the two second bevel gears 533 is rotatably connected to the top wall of the inner surface of the installation box 531. The upper end of the first bevel gear 532 is fixedly connected to the revolution drive assembly 52. One end of each of the two second bevel gears 533 away from the drive shaft 51 penetrates through the inner surface of the installation box 531 and is fixedly connected to the adjacent grinding roller 54.

[0044] Furthermore, to limit the first bevel gear 532 and prompt the second bevel gear 533 to rotate self, refer to Figure 5 , the revolution drive assembly 52 includes a fixed ring 521 fixedly connected to the top wall of the inner cavity of the mixing cylinder 1 and rotatably connected to the outer surface of the drive shaft 51. A number of limiting rods 522 are fixedly connected to the lower end of the fixed ring 521 in a circular distribution. A sliding ring 523 slidably connected to the outer surface of the drive shaft 51 is slidably connected to the outer surfaces of the number of limiting rods 522. The lower end of the sliding ring 523 is fixedly connected to the upper end of the first bevel gear 532.

[0045] When the drive shaft 51 rotates, it will drive the installation box 531 to rotate, so that the two second bevel gears 533 installed therein both revolve around the drive shaft 51. Synchronously, while the second bevel gear 533 revolves, since the fixed ring 521 and the limiting rods 522 are relatively fixed, the sliding ring 523 cannot rotate, and the first bevel gear 532 connected to it cannot rotate either. Therefore, the first bevel gear 532 is stationary relative to the second bevel gear 533. During the revolution of the second bevel gear 533, due to the meshing effect, it will rotate self under the action of the first bevel gear 532, thus driving the grinding roller 54 to rotate self while revolving.

[0046] Further, to guide the drive shaft 51 to drive the milling drive assembly 53 and the milling roller 54 to move up and down, and to pound and crush the solid fertilizer, refer to Figure 6 and Figure 7 , the inner surface of the conical plate 57 is fixedly connected to a central shaft 573 through a support rod. The inner surface of the central shaft 573 is rotationally connected to the outer surface of the drive shaft 51. The inner surface of the central shaft 573 is provided with a corrugated groove 571 that connects end to end. On the outer surface of the drive shaft 51, parts located within the path of the corrugated groove 571 are symmetrically fixedly connected to limit wheels 572 that are slidably connected to the inner surface of the corrugated groove 571.

[0047] The conical plate 57 is mainly used to block the toothed ring 62 to prevent fertilizer from falling on the toothed ring 62. Synchronously, by using the central shaft 573 provided in the central shaft 573, during the rotation of the drive shaft 51, the revolution drive assembly 52 can drive the drive shaft 51 to move up and down cyclically, and then drive the milling drive assembly 53 and the milling roller 54 to move up and down, so as to pound and break the agglomerated fertilizer, and further improve the processing efficiency.

[0048] Further, to prompt the pulverized solid fertilizer powder to pass through the screen 56, refer to Figure 8 , one side of the screening scraper 55 close to the drive shaft 51 is fixedly connected to the adjacent end face of the mounting box 531. The screening scraper 55 is trapezoidal, and a number of sieve holes 551 communicating with the lower end are opened at its upper end. A number of rubber scrapers 552 that are closely attached to the upper end of the screen 56 are linearly distributed and fixedly connected to the inner surface of the screening scraper 55.

[0049] The sieve holes 551 opened at the upper end of the screening scraper 55 are used for screening the solid fertilizer. Powders or small particles will enter the inner side of the screening scraper 55 and be scraped and rolled by the rubber scrapers 552 to make them pass through the pores on the screen 56, while the large agglomerated particles cannot enter.

[0050] Embodiment 3: On the basis of Embodiment 2, this embodiment further uses the cooperation of the transmission shaft 642 and the Y-shaped plate 631 to drive the Y-shaped plate 631 to rotate following the drive shaft 51. Then, through the cooperation of the toothed ring 62 and the spur gear 632, the stirring blade 633 is driven to rotate, and the water and fertilizer in the lower part of the inner cavity of the mixing cylinder 1 are stirred cyclically to ensure uniform distribution of the fertility therein, improve the water and fertilizer mixing efficiency, and further improve the distribution uniformity during fertilization and the absorption efficiency of vegetation.

[0051] Specifically, to realize the mixing and stirring of the solid fertilizer, refer to Figure 9 , the stirring assembly 63 includes a Y-shaped plate 631 located between the toothed ring 62 and the limit ring 67. A number of spur gears 632 meshing with the toothed ring 62 are rotationally connected in a circular distribution at the upper end of the Y-shaped plate 631. The lower ends of the spur gears 632 penetrate through the upper end of the Y-shaped plate 631 and extend to the lower end of the Y-shaped plate 631 and are fixedly connected to the stirring blades 633.

[0052] Furthermore, to drive the Y-shaped plate 631 to revolve around the axis of the drive shaft 51 and supply air to the connecting rod 64 by means of the air pump 61, the air slip ring 65 and the air supply pipe 66, providing bubble assistance for stirring and mixing, refer to Figure 9 and Figure 10 , a transmission shaft 642 which is fixedly connected to the upper end of the Y-shaped plate 631 and is slidably connected to the inner surface of the drive shaft 51 is provided. The lower end of the transmission shaft 642 penetrates through the upper end of the Y-shaped plate 631 and extends to the bottom wall of the inner cavity of the mixing cylinder 1 and is fixedly connected to the connecting rod 64. An air supply pipe 66 communicating with the air slip ring 65 is jointly provided on the transmission shaft 642, the connecting rod 64 and the drive shaft 51. The lower end of the connecting rod 64 is fixedly connected to an air diffuser pipe 641 communicating with the air supply pipe 66.

[0053] The transmission shaft 642 is slidable on the inner surface of the drive shaft 51 and can rotate following the rotation of the drive shaft 51, but will not move following the up and down movement of the drive shaft 51, thereby driving the Y-shaped plate 631 to rotate. During the rotation of the Y-shaped plate 631, the spur gear 632 inside its upper end can generate self-rotation under the action of the gear ring 62, thereby driving the stirring blade 633 to rotate and stirring the water fertilizer.

[0054] Synchronously, during the stirring, the air pump 61 supplies air into the air supply pipe 66 through the air slip ring 65, and then sends the air into the water fertilizer mixture in the lower part of the inner cavity of the mixing cylinder 1 in the form of bubbles through the transmission shaft 642 and the connecting rod 64. At the same time, the bubbles are ejected in a spiral form through the rotation of the connecting rod 64, and then the dissolution of the solid fertilizer particles in the water is further enhanced through the floating and bursting of the bubbles, improving the mixing efficiency and uniformity.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
