[0022] Please see Figure 1-4 This embodiment provides a technical solution: a mixing device for the production of water-soluble fertilizer, including a mixing cylinder 1, an installation unit 4, and a filter tube bottom 14;

[0023] Mixing cylinder 1: A main stirring rod 5 is rotatably connected to its middle section. The mixing cylinder 1 provides a mixing space for the raw materials. The lower end of the main stirring rod 5 is equipped with stirring blades 6. The main stirring rod 5 drives the stirring blades 6 to rotate, and the stirring blades 6 mix and stir the water in the lower layer. The upper end of the mixing cylinder 1 is equipped with a feed hopper 2. The solid raw materials of water-soluble fertilizer are first added into the feed hopper 2. The lower end of the feed hopper 2 is equipped with a filter tube 3. The upper end of the mixing cylinder 1 is rotatably connected with a secondary stirring rod 10. The lower end of the secondary stirring rod 10 extends through the feed hopper 2 into the interior of the filter tube 3. The lower end of the outer arc surface of the secondary stirring rod 10 is equipped with evenly distributed stirring blades 11. The secondary stirring rod 10 drives the stirring blades 11 to rotate, and the stirring blades 11 stir the raw materials inside the filter tube 3, promoting their dissolution and discharge with the liquid. The upper end of the outer arc surface of the main stirring rod 5 is equipped with evenly distributed rectangular blades 7. The rectangular plate 7 agitates the upper water, causing the water to flush the filter tube 3, thereby accelerating the dissolution and mixing of the raw materials. A control switch group 13 is provided on the outer arc surface of the mixing cylinder 1. The input end of the control switch group 13 is electrically connected to an external power source. An auxiliary motor 12 is provided on the left side of the upper surface of the mixing cylinder 1. The output shaft of the auxiliary motor 12 is fixedly connected to the upper end of the auxiliary stirring rod 10. A main motor 9 is provided on the right side of the upper surface of the mixing cylinder 1. A bevel gear 8 is provided on the left end of the output shaft of the main motor 9 and the upper end of the main stirring rod 5. The two bevel gears 8 are meshed and connected. When the main motor 9 runs, the output shaft of the main motor 9 drives the main stirring rod 5 to rotate through the two meshing bevel gears 8. The input ends of the auxiliary motor 12 and the main motor 9 are electrically connected to the output end of the control switch group 13. When the auxiliary motor 12 works, the output shaft of the auxiliary motor 12 drives the auxiliary stirring rod 10 to rotate.

[0024] Filter tube bottom 14: It is located below filter tube 3. Insoluble impurities accumulate inside filter tube bottom 14. Filter tube bottom 14 can pass through the through hole at the upper end of mixing cylinder 1 to facilitate the removal of insoluble impurities in the raw materials.

[0025] Mounting unit 4: Used for fixing the filter tube bottom 14. Mounting unit 4 includes a connecting rod 41, a handwheel 42, and a pressure plate 43. The connecting rod 41 is movably inserted into the upper end of the mixing cylinder 1, and the lower end of the connecting rod 41 is fixedly connected to the filter tube bottom 14. The upper end of the connecting rod 41 is threadedly connected to the handwheel 42, and the lower end of the handwheel 42 is rotatably connected to the pressure plate 43. The pressure plate 43 is located on the upper side of the upper surface of the mixing cylinder 1, ensuring that the handwheel 42 is above the mixing cylinder 1. Rotating the handwheel 42, the handwheel 42 is threadedly connected to the connecting rod 41, thereby causing the connecting rod 41 to move the filter tube bottom 14 downward, and the auxiliary stirring rod 10 moves out from the inside of the filter tube bottom 14. Mounting unit 4 It also includes a rectangular positioning block 44 and a baffle 45. The rectangular positioning block 44 is located at the upper end of the outer arc surface of the connecting rod 41 and restricts the rotation of the connecting rod 41. The baffle 45 is located on the lower surface of the pressure plate 43. Both the rectangular positioning block 44 and the baffle 45 are movably inserted into the through hole on the upper surface of the mixing cylinder 1. The baffle 45 blocks the through hole. The installation unit 4 also includes a handle strip 46. The handle strip 46 is located at the upper end of the connecting rod 41. By controlling the handle strip 46 to rotate the connecting rod 41, the connecting rod 41 drives the filter tube bottom 14 to rotate 180 degrees and no longer correspond to the filter tube 3. Then, the handle strip 46 is pulled upward, and the handle strip 46 drives the connecting rod 41 to move upward.

[0026] The working principle of the mixing device for water-soluble fertilizer production provided by this utility model is as follows: First, the solid raw material of the water-soluble fertilizer is added to the inside of the feed hopper 2. The raw material slides into the filter tube 3 and the filter tube bottom 14, forming a whole. Then, liquid raw material is added to the inside of the feed hopper 2. Simultaneously, the control switch group 13 is adjusted, and the auxiliary motor 12 operates. The output shaft of the auxiliary motor 12 drives the stirring blade 11 to rotate via the auxiliary stirring rod 10. The stirring blade 11 stirs the raw material inside the filter tube 3, causing it to dissolve and flow out with the liquid from the filter tube 3 and the filter tube bottom 14. The raw materials are discharged through the circular holes on the surface of the bottom 14, allowing for initial dissolution and mixing. After the raw materials are added, the lower end of the filter tube 3 is immersed in the liquid. The raw materials in the filter tube 3 will dissolve in the upper layer of the water. Simultaneously, the main motor 9 operates, and the output shaft of the main motor 9 drives the main stirring rod 5 to rotate through two meshing bevel gears 8. The main stirring rod 5 drives the stirring blades 6 and rectangular plates 7 to rotate. The stirring blades 6 mix and stir the lower layer of water, while the rectangular plates 7 agitate the upper layer of water, causing the water to flush the filter tube 3, thereby accelerating the dissolution of the raw materials. After mixing and stirring for a period of time, the auxiliary motor 12 and the main motor 9 stop running. Then, the valve below the mixing cylinder 1 is opened to discharge the mixed water-soluble fertilizer. Insoluble impurities in the raw materials will accumulate inside the bottom 14 of the filter tube. Then, the handwheel 42 is rotated. The handwheel 42 is threadedly connected to the connecting rod 41. The rectangular positioning block 44 restricts the rotation of the connecting rod 41, which in turn causes the connecting rod 41 to move the bottom 14 of the filter tube downward. The auxiliary stirring rod 10 moves out of the bottom 14 of the filter tube, and at the same time, the rectangular positioning block 44 moves out of the rectangular groove on the upper side wall of the mixing cylinder 1. Then, the rotation of the connecting rod 41 is no longer restricted. The connecting rod 41 is rotated by the control handle bar 46. The connecting rod 41 drives the bottom of the filter tube 14 to rotate 180 degrees and no longer correspond to the filter tube 3. Then, the handle bar 46 is pulled upward. The handle bar 46 drives the connecting rod 41 to move upward. The connecting rod 41 drives the handwheel 42, the rectangular positioning block 44, the bottom of the filter tube 14, the pressure plate 43, and the baffle 45 to move upward. The rectangular positioning block 44 and the bottom of the filter tube 14 can pass through the through hole at the upper end of the mixing cylinder 1, which facilitates the removal of insoluble impurities in the raw materials, thereby ensuring the production quality of water-soluble fertilizer.

[0027] It is worth noting that the auxiliary motor 12 and the main motor 9 disclosed in the above embodiments can be freely configured according to the actual application scenario. The main motor 9 can be a three-phase asynchronous motor of model Y112M-4, and the auxiliary motor 12 can be a DC brushless motor of model 80BLDC. The control switch group 13 is equipped with switch buttons corresponding to the auxiliary motor 12 and the main motor 9 for controlling their switching operation.
