By grinding and crushing the water-soluble fertilizer, the granular water-soluble fertilizer can be ground into powder and put into the water in the pretreatment barrel, thereby greatly improving the dissolution efficiency of the water-soluble fertilizer and avoiding the precipitation of the water-soluble fertilizer in the pretreatment barrel; since the influence of the sediment on the inside of the equipment, especially the wear on the pump and other mechanical parts, is reduced, the service life of the relevant agricultural facilities is extended as a whole, and the replacement and maintenance costs are reduced.

[0013] 2. When the water-soluble fertilizer is dissolved, the stirring shaft drives the stirring blades to rotate, and the stirring blades stir the water-soluble fertilizer, accelerate the dissolution of the powdered water-soluble fertilizer in the water, and improve the dissolution effect of the water-soluble fertilizer. The arc-shaped stirring plate in the circulating material turning component rotates, and can stir in the vertical direction to achieve the turbulence effect on the water and fertilizer in the pretreatment barrel, and can drive the bottom water and fertilizer to move upward, thereby avoiding the formation of precipitation at the bottom of the pretreatment barrel; the stirring component and the circulating material turning component work together, not only promoting uniform mixing in the horizontal direction, but also strengthening the stirring effect in the vertical direction. In this way, the concentration of the solution in the pretreatment barrel can be ensured to be consistent, avoiding the precipitation problem caused by excessive local concentration.

[0014] 3. When the device is in use, the granular fertilizer is crushed into finer powder through the grinding and feeding assembly, which increases the contact area between the fertilizer and water, thereby accelerating the dissolution rate. This helps to ensure that the nutrients in the fertilizer can be more fully absorbed and utilized by the plants, reducing nutrient loss; at the same time, the crushed fertilizer is easier to flow in the irrigation system, reducing the risk of pipes or nozzles being blocked by large particles, and ensuring the long-term stable operation of the irrigation system.

The above working principle: when the device is fertilizing, irrigation water is injected into the pretreatment barrel 20 through the water inlet pipe 201, and the granular water-soluble fertilizer is added into the pretreatment barrel 20 through the lower hopper 30. The fertilizer enters the horizontally arranged feeding barrel 401 from the lower hopper 30. Inside the feeding barrel 401, the rotating shaft 403 drives the auger 404 to rotate, and the fertilizer is gradually pushed between the fixed grinding disc 405 and the active grinding disc 406. The fixed grinding disc 405 and the active grinding disc 406 are arranged opposite to each other. When the rotating shaft 403 rotates, the active grinding disc 406 is driven by the rotating shaft 403. The grinding disc 406 rotates accordingly and interacts with the fixed grinding disc 405 to grind the passing fertilizer and crush it into finer powder. The ground water-soluble fertilizer falls into the water in the pretreatment barrel 20 through the opening at the bottom of the protective shell 402. The ground fine fertilizer powder falls into the water and begins to dissolve. The rotation of the stirring assembly 50 realizes the stirring of the irrigation water, further promoting the dissolution of the fertilizer. When the fertilizer is completely dissolved and fully mixed, it can be discharged from the pretreatment barrel 20 through the drain pipe 202 for irrigation or further use.

[0019] The stirring assembly 50 includes: a stirring shaft 501, the stirring shaft 501 is rotatably installed at the center of the bottom surface of the inner wall of the pretreatment barrel 20, the lower end of the stirring shaft 501 is connected to the bottom surface bearing of the inner wall of the pretreatment barrel 20, and the stirring shaft 501 is connected to the rotating shaft 403 through the transmission assembly 60; stirring blades 502, a plurality of evenly distributed stirring blades 502 are fixedly installed on the periphery of the stirring shaft 501; the outer side of the stirring blade 502 is provided with a circulating material turning assembly 70 connected to the stirring blade 502.

[0020] When the device is in use, the driving motor is energized to drive the rotating shaft 403 connected thereto to rotate. At the same time, the rotating shaft 403 drives the stirring shaft 501 to rotate through the transmission assembly 60. The stirring shaft 501 drives the stirring blade 502 connected thereto to rotate synchronously. The rotation of the stirring blade 502 realizes the stirring of the irrigation water in the pretreatment barrel 20, thereby promoting uniform mixing of the fertilizer.

[0021] The transmission assembly 60 includes: a transmission shaft 601, a horizontally arranged transmission shaft 601 is rotatably installed inside the pretreatment barrel 20, both ends of the transmission shaft 601 are respectively connected to the corresponding side bearings of the inner wall of the pretreatment barrel 20, and the transmission shaft 601 is located above the stirring shaft 501; a main synchronous wheel 602, a main synchronous wheel 602 is fixedly installed at one end of the rotating shaft 403 located outside the protective shell 402; a secondary synchronous wheel 603, a secondary synchronous wheel 603 arranged opposite to the main synchronous wheel 602 is fixedly installed on one side of the transmission shaft 601, and the main synchronous wheel 602 and the secondary synchronous wheel 603 are connected by a transmission belt 604; a first bevel gear 605, a first bevel gear 605 is fixedly installed in the middle of the transmission shaft 601; a second bevel gear 606, a second bevel gear 606 meshing with the first bevel gear 605 is fixedly installed on the upper end of the stirring shaft 501.

[0022] When the device is working, when the rotating shaft 403 rotates, the main synchronous wheel 602 fixed thereon also starts to rotate. The main synchronous wheel 602 is connected to the auxiliary synchronous wheel 603 through the transmission belt 604. Due to the action of the transmission belt 604, the auxiliary synchronous wheel 603 will rotate with the main synchronous wheel 602. In this way, the power of the rotating shaft 403 is transmitted to the transmission shaft 601. The first bevel gear 605 fixedly installed in the middle of the transmission shaft 601 can rotate with the transmission shaft 601. The first bevel gear 605 is meshed with the second bevel gear 606 fixed at the upper end of the stirring shaft 501. The meshing action between the first bevel gear 605 and the second bevel gear 606 can change the direction of the force, so that the original horizontal rotational motion is converted into a vertical rotational motion. Therefore, when the first bevel gear 605 rotates, it will drive the second bevel gear 606 and the entire stirring shaft 501 to rotate, thereby achieving a stirring effect on the irrigation water.

[0023] The circulating material turning component 70 includes: a shell 701, the shell 701 is sleeved on the stirring shaft 501, the stirring shaft 501 vertically penetrates the shell 701 and is connected to its bearing; a horizontal shaft 702, through holes are respectively provided on both sides of the shell 701, and the horizontal shaft 702 is respectively installed with bearings in the through holes; an arc stirring plate 703, the outer end of the horizontal shaft 702 is fixedly installed with an arc stirring plate 703; an L-shaped bracket 704, the L-shaped bracket 704 is respectively fixed on both sides of the shell 701; an inner gear ring 705, the lower end of the L-shaped bracket 704 is jointly fixedly installed with the inner gear ring 705, the lower end of the L-shaped bracket 704 is fixedly connected to the top surface of the inner gear ring 705, the stirring shaft 501 vertically penetrates the inner gear ring 705 and is coaxially arranged with it; a fixed shaft 706, a side of the bottom surface of the inner wall of the pretreatment barrel 20 is fixedly installed A fixed shaft 706, wherein the fixed shaft 706 is located in the inner gear ring 705; a first gear 707, wherein the first gear 707 is fixedly installed on the lower part of the stirring shaft 501; a second gear 708, wherein the upper bearing of the fixed shaft 706 is installed with a second gear 708 meshing with the first gear 707, and the second gear 708 is meshing with the inner gear ring 705 at the same time; a third bevel gear 709, wherein the third bevel gear 709 is fixedly installed on the middle part of the stirring shaft 501, and the third bevel gear 709 is located in the housing 701; a fourth bevel gear 710, wherein the inner end of the horizontal shaft 702 is fixedly installed with a fourth bevel gear 710 meshing with the third bevel gear 709, and a plurality of evenly distributed scrapers are fixedly installed on the outer side of the inner gear ring 705, wherein the scrapers are all inclined, and the bottom of the scrapers is slidably matched with the bottom surface of the inner wall of the pretreatment barrel 20.

[0024] When the irrigation water in the pretreatment barrel 20 is stirred, the stirring shaft 501 drives the first gear 707 fixed at the lower part thereof to rotate, and the second gear 708 meshing with it rotates synchronously at this time, and the second gear 708 drives the inner gear ring 705 with its core to rotate at the same time, so that the entire shell 701 performs a circular motion around the stirring shaft 501. During the rotation of the shell 701, the horizontal shaft 702 installed on the bearings on both sides of the shell 701 drives the corresponding first bevel gear 710 to rotate. The rotation speeds of the shell 701 and the stirring shaft 501 are different. At this time, the fourth bevel gear 710 meshing with the third bevel gear 709 can drive the corresponding horizontal shaft 702 and the arc-shaped stirring plate 703 connected thereto to rotate around their respective axes. The rotation of the stirring shaft 501 not only directly drives the arc-shaped stirring plate 703 to perform local stirring, but also makes the entire shell 701 and the stirring plate thereon perform an overall circular rotation through the gear and inner gear ring mechanism, thereby ensuring that the materials in the pretreatment barrel 20 are efficiently and evenly turned and mixed.

[0025] A water pump 80 is fixedly mounted on the top surface of the four bases 10, and the lower end of the drain pipe 202 is fixedly connected to the water inlet of the water pump 80.
