Description

Technical Field

[0001] The utility model relates to an intelligent water-fertilizer integrated machine. Background Art

[0002] The intelligent water-fertilizer integrated machine is an intelligent device that uses water-fertilizer integrated technology for fertilization. It can adjust soluble solid or liquid fertilizers into fertilizer liquid of appropriate proportion according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, and then fertilize the crops.

[0003] During the operation of the intelligent water-fertilizer integrated machine, soluble solid or liquid fertilizers enter the fertilizer barrel through the feeding port or infusion joint on the fertilizer barrel. At the same time, irrigation water enters the fertilizer barrel through the water inlet joint on the fertilizer barrel, and then is stirred by the stirring device inside the fertilizer barrel to mix the soluble solid or liquid fertilizers with the irrigation water into the actually required fertilizer liquid, and finally flows out from the water outlet joint of the fertilizer barrel to the corresponding pipe for fertilization. The stirring device in the fertilizer barrel of the traditional intelligent water-fertilizer integrated machine uses a motor to drive the stirring blades to rotate. This stirring method only uses centrifugal force to mix the fertilizer and irrigation water. The stirring method is relatively rough, and it is difficult to ensure that the fertilizer can be fully mixed with the irrigation water. The proportion of fertilizer contained in the final fertilizer liquid will deviate from the actually required proportion, affecting the fertilization effect.

[0004] When the fertilizer is not fully mixed with the irrigation water, some of the fertilizer will adhere to the inner wall of the fertilizer barrel before flowing out. The fertilizer required for mixing the fertilizer liquid in the fertilizer barrel each time is not necessarily the same. At this time, the remaining fertilizer will pollute the new fertilizer liquid and affect the quality of the new fertilizer liquid. If the fertilizer remaining on the inner wall of the fertilizer barrel is to be cleaned, the entire stirring device must be removed from the fertilizer barrel, and then the inner wall of the fertilizer barrel must be scrubbed clean with a brush. The entire cleaning process is extremely troublesome and seriously affects the cleaning efficiency. Summary of the invention

[0005] The utility model aims to solve the existing technical problem by providing an intelligent integrated fertilizing machine, which can not only ensure that the fertilizer can be fully mixed with the irrigation water to form a fertilizer liquid with an actual required proportion, but also can quickly clean the inside of the fertilizing barrel to ensure cleaning efficiency.

[0033] A tubular lower outer connecting portion 48 is extended downward from the outer edge of the lower end surface of the fertilizer barrel 2; a tubular upper inner connecting portion 49 is extended upward from the inner edge of the upper end surface of the barrel seat 10, and the upper inner connecting portion 49 is embedded in the lower outer connecting portion 48; the upper inner connecting portion 49 is provided with a plurality of third screw holes 50 evenly distributed on the circumference; the outer wall of the lower outer connecting portion 48 is provided with a plurality of second countersunk holes 51 which are connected with the third screw holes 50; the third screws 52 pass through the second countersunk holes 51 and are screwed to the third screw holes 50; an annular lower sealing groove 53 is provided on the outer edge of the upper end surface of the barrel seat 10; a lower sealing ring 54 which matches it is provided in the lower sealing groove 53; the outer wall on the right side of the lower part of the barrel seat 10 is provided with a drainage joint 55 which is connected with its internal space, and a sealing cover 56 which matches it is screwed to the right end port of the drainage joint 55.

[0034] An auxiliary conical surface 57 which is wider at the top and narrower at the bottom is provided at the outer edge of the notch at the upper end of the stirring tank 18 .

[0035] The method of using the utility model is as follows:

[0036] Liquid fertilizer can be directly delivered to the barrel cover 4 through the infusion connector 5, and fixed fertilizer can be added into the barrel cover 4 through the feeding hole 7. When it is necessary to add fertilizer through the feeding hole 7, the plug 8 can be first unscrewed from the feeding hole 7 by screwing the cover 9, and the irrigation water used for mixing the fertilizer can enter the barrel cover 4 through the water inlet connector 6.

[0037] When the fertilizer enters the barrel cover 4, the fertilizer will fall into the stirring tank 18 under the action of gravity, and the irrigation water entering the barrel cover 4 will also enter the stirring tank 18 and come into contact with the fertilizer. At this time, the motor 12 can be started. When the motor 12 is started, the motor shaft 1201 of the motor 12 will drive the rotating shaft 16 to rotate, thereby realizing the synchronous rotation of the stirring seat 17. When the stirring seat 17 rotates, the stirring blade 19 will rotate accordingly. At this time, the stirring blade 19 will fully stir and mix the fertilizer and irrigation water in the stirring tank 18. Since the stirring seat 17 generates centrifugal force, when the stirring blade 19 stirs and mixes the fertilizer and irrigation water in the stirring tank 18, the mixed fertilizer liquid will be thrown outward, so that it can be far away. The mixing tank 18 is separated from the liquid hole 21, thereby effectively mixing the fertilizer liquid for a time to stay in the mixing tank 18, effectively prolonging the mixing time, and further fully mixing the fertilizer and the irrigation water. As the mixing tank 18 is filled with fertilizer liquid, a portion of the fertilizer liquid will be directly squeezed into the liquid hole 21, and then enter the drainage tank 20. In the process of a portion of the fertilizer liquid being squeezed into the liquid hole 21, the other portion of the fertilizer liquid will impact the inner groove wall of the mixing tank 18. This impact can break up the undissolved fertilizer in the irrigation water, making it easier to mix evenly in the irrigation water, further ensuring the mixing quality of the fertilizer liquid. After the fully mixed fertilizer liquid enters the drainage tank, it will directly fall downward into the bucket seat 10, and finally be sent from the water outlet joint to the pipeline connected thereto for fertilization.

[0038] A plurality of scrapers 22 evenly distributed in a circle are provided on the outer edge of the lower surface of the stirring seat 17. The scrapers 22 are in contact with the inner wall of the fertilizer barrel 2, and the lower ends of the scrapers 22 extend into the barrel seat 10. The lower ends of the scrapers 22 are in contact with the inner circumference of the barrel seat 10. When the stirring seat 17 rotates, the scrapers 22 will rotate synchronously. Even if some fertilizer liquid or fertilizer adheres to the inner wall of the fertilizer barrel 2, it will be directly scraped off by the scrapers 22, thereby effectively avoiding adhesion. The scraped fertilizer liquid or fertilizer can be dissolved again when most of the fertilizer flows, further ensuring the quality of the fertilizer liquid. When the inner walls of the fertilizer barrel 2 and the inner walls of the barrel seat 10 are scraped and cleaned, only clean water needs to be introduced in the later stage to thoroughly ensure the cleanliness of the inside of the fertilizer barrel 2 without affecting the new fertilizer put in later.

[0039] If it is necessary to thoroughly clean the inside of the fertilizer barrel 2, the second screw 45 can be directly unscrewed to separate the barrel cover 4 from the fertilizer barrel 2, and then the fixing screw 26 can be unscrewed from the screw hole 25 through the upper end port of the fertilizer barrel 2. At this time, it is only necessary to lift the stirring seat 17 to directly remove the stirring seat 17 and the scraper 22 from the fertilizer barrel 2. The entire disassembly process is extremely simple. After losing the interference of the stirring seat 17, a high-pressure water gun or other high-pressure equipment can be used to flush high-pressure water into the fertilizer barrel 2, so that the fertilizer barrel 2 can be fully cleaned, and the sewage after cleaning can be discharged through the drainage joint 55. Before using the drainage joint 55, the sealing cover 56 screwed to the outside of the drainage joint 55 can be unscrewed, and then the corresponding drainage pipeline can be connected to facilitate the discharge of sewage.

[0040] In summary, the utility model can gather fertilizer and irrigation water in the stirring tank 18, and then use the stirring blades 19 in the stirring tank 18 to stir and mix the fertilizer and irrigation water. The plurality of stirring blades 19 can hit the fertilizer and irrigation water multiple times every time the stirring seat 17 rotates one circle, so that the two are mixed more evenly and fully, and the centrifugal force generated by the rotation of the stirring seat 17 can be used to effectively prolong the time that the fertilizer and irrigation water are in the stirring tank 18, effectively prolong the stirring time, further improve the uniformity during stirring, and ensure that the fertilizer is fully dissolved in the irrigation water to the greatest extent. Finally, before the fertilizer liquid mixed with the fertilizer and the irrigation water enters the drainage trough 20 through the liquid through hole 21, the fertilizer and the irrigation water in the stirring tank 18 can be further mixed by utilizing the suddenly narrowed aperture of the liquid through hole 21, thereby ensuring the mixing ratio of the fertilizer and the irrigation water to the greatest extent, thereby effectively ensuring the quality of the fertilizer. At the same time, the scraper 22 will rotate synchronously with the stirring seat 17, and the scraper 22 can effectively scrape off the fertilizer or fertilizer liquid adhering to the inner wall of the fertilizer barrel 2 to avoid adhesion, thereby effectively ensuring the cleanliness of the fertilizer barrel 2 after use, and effectively avoiding affecting the ratio of the new fertilizer next time.

[0041] The end of the liquid through hole 21 that intersects the drainage groove 20 is inclined upward. This structural design can effectively prolong the time for the fertilizer liquid in the stirring groove 18 to enter the drainage groove 20 through the liquid through hole 21, and at the same time effectively increase the degree of dispersion formed when the fertilizer liquid impacts the hole opening that intersects the liquid through hole 21 and the stirring groove 18, further ensuring that the fertilizer is fully dissolved in the irrigation water.

[0042] An annular auxiliary groove 29 is provided on the inner wall of the upper end port of the fertilizing barrel 2, and a rotating plate 30 is provided on the outer wall of the upper end of the stirring seat 17, which is in contact with the lower side groove wall of the auxiliary groove 29. A blocking ring 31 is extended upward from the outer edge of the upper end of the rotating plate 30, and the outer peripheral surface of the blocking ring 31 is in contact with the inner peripheral surface of the auxiliary groove 29. When the stirring seat 17 rotates, the blocking ring 31 rotates synchronously. When the fertilizer liquid in the stirring tank 18 splashes onto the inner wall of the blocking ring 31, it will be directly thrown back into the stirring tank 18 by the inner wall of the blocking ring 31.

[0043] The outer groove wall of the stirring tank 18 is provided with a plurality of disassembly holes 32 corresponding to the positions of the stirring blades 19. The center of the end of the stirring blade 19 opposite to the outer groove wall of the stirring tank 18 is provided with a screw joint 33 screwed to the disassembly hole 32. This fixing method is conducive to the disassembly and assembly of the stirring blade 19, thereby facilitating the replacement of stirring blades 19 of different models. Different models of stirring blades 19 can be targeted at different fertilizers, which is more conducive to the dissolution of fertilizers in irrigation water.

[0044] The outer wall of the protective cover 13 is provided with a guide cone 34 which is narrow at the top and wide at the bottom. When the fertilizer liquid flows downward through the notch at the lower end of the drainage groove 20, it can flow to the water outlet joint 11 faster under the guidance of the guide cone 34, which is convenient for the transportation of the fertilizer liquid.

[0045] A fixing portion 35 is provided on the outer wall of the lower end of the protective cover 13, and a plurality of evenly distributed first through holes 36 are provided on the fixing portion 35. A plurality of first screw holes 37 which are connected with the first through holes 36 are provided on the inner wall of the lower side of the barrel seat 10. The first screw 38 passes downward through the first through holes 36 and is screwed into the first screw hole 37. This fixing method can not only effectively ensure the stability of the motor 12, but also facilitate the protection of the motor 12.

[0046] An annular groove 39 is provided on the inner wall of the rotating hole 14, and an O-ring 40 is provided in the annular groove 39 and is sleeved on the outside of the motor shaft 1201 of the motor 12. The presence of the O-ring 40 can effectively ensure the sealing between the inner wall of the rotating hole 14 and the motor shaft 1201 of the motor 12, thereby preventing the fertilizer liquid from leaking into the protective cover 13 and invading the motor 12.

[0047] A tubular upper outer connecting portion 41 is extended upward from the outer edge of the upper end surface of the fertilizer barrel 2, and a tubular lower inner connecting portion 42 is extended downward from the inner edge of the lower end surface of the barrel cover 4. The lower inner connecting portion 42 is embedded in the upper outer connecting portion 41. The outer wall of the lower inner connecting portion 42 is provided with a plurality of second screw holes 43 evenly distributed around the circumference, and the outer wall of the upper outer connecting portion 41 is provided with a plurality of first countersunk holes 44 intersecting the second screw holes 43. The second screws 45 pass through the first countersunk holes 44 and are screwed into the second screw holes 43. This fixing method is conducive to the disassembly and assembly between the fertilizer barrel 2 and the barrel cover 4, and is convenient for the disassembly and assembly of the internal components of the fertilizer barrel 2.

[0048] An annular upper sealing groove 46 is provided on the outer edge of the lower end surface of the barrel cover 4, and an upper sealing ring 47 matching it is provided in the upper sealing groove 46. The existence of the upper sealing ring 47 can effectively ensure the sealing between the lower end surface of the barrel cover 4 and the upper end surface of the fertilizer barrel 2 to avoid leakage.

[0049] A tubular lower outer connecting portion 48 is extended downward from the outer edge of the lower end surface of the fertilizer barrel 2, and a tubular upper inner connecting portion 49 is extended upward from the inner edge of the upper end surface of the bucket seat 10. The upper inner connecting portion 49 is embedded in the lower outer connecting portion 48. The upper inner connecting portion 49 is provided with a plurality of third screw holes 50 uniformly distributed around the circumference, and the outer wall of the lower outer connecting portion 48 is provided with a plurality of second countersunk holes 51 which are connected with the third screw holes 50. The third screws 52 pass through the second countersunk holes 51 and are screwed to the third screw holes 50. This fixing method can not only effectively ensure the stability between the fertilizer barrel 2 and the bucket seat 10, but also facilitate the disassembly and assembly between the fertilizer barrel 2 and the bucket seat 10.

[0050] An annular lower sealing groove 53 is provided on the outer edge of the upper end surface of the bucket seat 10, and a matching lower sealing ring 54 is provided in the lower sealing groove 53. The existence of the lower sealing ring 54 can effectively ensure the sealing between the upper end surface of the bucket seat 10 and the lower end surface of the fertilizer bucket 2.

[0051] An auxiliary conical surface 57 which is wide at the top and narrow at the bottom is provided at the outer edge of the notch at the upper end of the mixing tank 18. The auxiliary conical surface 57 can quickly guide fertilizer and irrigation water into the mixing tank 18 for mixing.
