Description

Technical Field

[0001] This invention relates to the field of liquid fertilizer technology for fruit trees, specifically to a liquid fertilizer application device for fruit trees. Background Technology

[0002] Suspension liquid compound fertilizers have high nutrient content. They are highly concentrated saturated solutions, and their nutrient content is comparable to that of traditional powdered water-soluble fertilizers containing macronutrients and even general compound fertilizers, significantly higher than that of clear liquid fertilizers. For example, some high-quality suspension fertilizers can have a nutrient content of 40% or even higher, which is 2 to 3 times that of traditional liquid fertilizers.

[0003] During the topdressing process for mangoes, a suspension liquid compound fertilizer is used. The existing suspension liquid compound fertilizer is stored in buckets, each sealed with a lid. When topdressing, the lid is first opened, and then a certain ratio of water is added, such as a 1:5 ratio of suspension liquid compound fertilizer to water. The staff uses a long-arm ladle to thoroughly stir the suspension liquid compound fertilizer in the bucket, and then pours the suspension liquid compound fertilizer directly onto the uphill part of the fruit tree through the long-arm ladle.

[0004] However, manual mixing relies on the operator's experience and physical strength, making it difficult to ensure that the mixing force, time, and scope are completely consistent each time. This results in uneven fertilizer concentration in different areas of the container. Some areas have excessively high fertilizer concentrations, causing localized nutrient overload on the mango trees, leading to root burn and leaf scorching. On the other hand, some areas have excessively low fertilizer concentrations, which cannot meet the nutritional needs of mango growth, affecting the yield and quality of the mangoes. Therefore, we propose a liquid fertilizer application device for fruit trees. Summary of the Invention

[0063] The pusher 85 includes a pusher gear 851, a pusher rack 852, a pusher plate 853, a pusher support rod 854, and a rotating plate 855. The pusher gear 851 is fixedly sleeved on the outside of the support shaft 845, and the pusher gear 851 is meshed with the pusher rack 852. The pusher rack 852 is fixedly installed on the bottom of the pusher plate 853. A slide rail is provided on one side of the support plate 846, and the pusher plate 853 is slidably sleeved on the outside of the slide rail.

[0064] One end of the push rod 854 is rotatably connected to the push plate 853 via a hinge support, and the other end of the push rod 854 is rotatably connected to the rotating plate 855 via a hinge support. The rotating plate 855 is rotatably sleeved on the outside of the crossbar 54.

[0066] The stirring assembly 6 includes a rotating frame 61, a rotating component 62, a vertical rod 63, a rotating gear 64, an external gear disk 65, and a stirring component 66. The rotating frame 61 is rotatably sleeved on the outside of the support platform 81. The rotating component 62 is disposed on the sealing cover plate 3 and is used to drive the rotating frame 61.

[0067] The vertical rod 63 is provided in multiple ways, and the rotating frame 61 is provided with multiple extensions 8551, and the vertical rod 63 is rotatably connected to the bottom of the extension 8551;

[0068] Rotating gear 64 is fixedly sleeved on the top of vertical rod 63, and external gear disk 65 is fixedly sleeved on the outside of liquid guide tube 4. Multiple rotating gears 64 are meshed with external gear disk 65, and the width of rotating gear 64 is greater than the width of external gear disk 65.

[0069] The stirring element 66 is installed on the outside of the vertical rod 63, and the guide element 67 is also provided on the outside of the liquid guide tube 4. The guide element 67 is connected to multiple stirring elements 66.

[0070] As a further supplementary explanation, the stirring component 66 includes a rotating sleeve 661 and a stirring disc 662. The rotating sleeve 661 is slidably sleeved on the outside of the vertical rod 63. Multiple stirring discs 662 are provided, and multiple stirring discs 662 are respectively fixedly sleeved on the outside of the rotating sleeve 661. The stirring disc 662 is provided with an inlet 6621, and the outer wall of the stirring disc 662 is provided with an outlet hole 6622. Multiple stirring blades are also fixedly installed inside the stirring disc 662.

[0071] In this application, multiple mixing discs 662 are alternately installed on the rotating sleeve 661 with the inlet 6621 facing upwards or downwards. As the rotating sleeve 661 rotates, it synchronously drives the multiple mixing discs 662 to rotate synchronously. As the mixing discs 662 rotate, a vortex is generated at the inlet 6621. At this time, the suspended compound fertilizer and water enter through the inlet 6621. At the same time, multiple mixing blades mix and stir the suspended compound fertilizer and water. As the mixing discs 662 rotate, the mixed suspended compound fertilizer is discharged through multiple outlet holes 6622. This process is repeated to achieve the effect of fully and evenly mixing the suspended compound fertilizer.

[0072] The guide component 67 includes a guide sleeve 671, a guide rod 672 and a connecting sleeve 673. The guide sleeve 671 is slidably sleeved on the outside of the liquid guide tube 4, and the guide sleeve 671 is fixedly installed at the bottom of the two lifting screws 82. In this application, the external gear disk 65 is provided with through holes corresponding to the positions of the two lifting screws 82.

[0073] The guide sleeve 671 has a continuous V-groove 6711 on its outer periphery. Multiple guide rods 672 are provided. One end of the multiple guide rods 672 is slidably connected to the V-groove 6711, and the other end of the guide rod 672 is fixedly connected to the connecting sleeve 673. The connecting sleeve 673 is rotatably sleeved on the outside of the top of the rotating sleeve 661.

[0074] Specific implementation process: When the sealing cover plate 3 is sealed to the top of the barrel 1, the rotating component 62 drives the rotating frame 61 to rotate relative to the support platform 81. As the rotating frame 61 rotates, it drives multiple vertical rods 63 to rotate around the outside of the support platform 81. At the same time, due to the meshing of the rotating gear 64 on the vertical rod 63 with the external gear disk 65, the rotating gear 64 causes the vertical rod 63 to rotate. As the vertical rod 63 rotates, it causes multiple stirring discs 662 on it to rotate, generating eddies at multiple points at the bottom, thus achieving full mixing of the suspended liquid compound fertilizer. At the same time, under the limiting action of the V-groove 6711 of the guide sleeve 671, the suspended liquid compound fertilizer inside the barrel 1 is pushed upward or downward during mixing, thereby ensuring that the suspended liquid compound fertilizer is fully mixed.

[0075] Please see Figures 11 to 12 The export component 7 includes an export frame 71, an upper opening tube 72, and an export element 73. The export frame 71 is installed at the bottom of multiple vertical rods 63, and the vertical rods 63 are rotatably connected to the export frame 71. A connecting rod 74 is fixedly installed on the export frame 71, and the connecting rod 74 slides through the bottom of the liquid guide tube 4. The upper opening tube 72 is fixedly installed on the connecting rod 74, and the upper opening tube 72 is rotatably connected to the inner wall of the liquid guide tube 4. Multiple liquid inlet holes 43 are arranged around the bottom of the liquid guide tube 4. The export element 73 is installed on the upper opening tube 72, and the opening tube provides a sealing effect on the liquid inlet holes 43.

[0076] The export component 73 includes an export rod 731 and an export spiral blade 732. The export rod 731 is fixedly installed on the upper open tube 72, and the export spiral blade 732 is fixedly sleeved on the outside of the export rod 731. The export spiral blade 732 is located inside the liquid guide tube 4.

[0077] Specific implementation process: In this application, when the mango tree is not fertilized, the rotating part 62 operates, keeping the inside of the barrel 1 in a state of constant stirring. When moving to the fertilization point where the mango tree needs fertilization, the worker only needs to push the extension 8551 to rotate the rotating plate 855. As the rotating plate 855 rotates, it drives the pusher plate 853 to move relative to the slide rail via the pusher rod 854. As the pusher plate 853 moves, it causes the pusher rack 852 to move relative to the pusher gear 851, causing the pusher gear 851 to rotate. As the pusher gear 851 rotates, it drives the worm gear 844 to rotate via the support shaft 845. The worm gear 844 then drives the worm wheel 843 to rotate. 3. The rotating shaft 841 rotates, and at the same time the rotating shaft 841 rotates, it drives the transmission wheel assembly 842 to rotate synchronously. At this time, the two threaded sleeves 83 rotate, thereby providing driving force to the two lifting screws 82 synchronously. The two lifting screws 82 move vertically downward relative to the sealing cover plate 3. When the lifting screws 82 move downward, on the one hand, they drive the support platform 81 and the guide sleeve 671 to move downward, and on the other hand, they drive the outlet frame 71 to move downward, thereby causing the outer wall of the opening pipe to deviate from the liquid inlet hole 43. At this time, as the outlet frame 71 rotates, it drives the outlet rod 731 and the outlet spiral blade 732 to rotate, thereby realizing the export of the mixed suspended liquid compound fertilizer, which is finally sprayed out through the nozzle 42 of the fertilizer pipe 41.

[0078] Furthermore, according to this application, no manual fertilization is required; simply pushing the handle 56 allows for targeted and thorough liquid fertilization of the mango tree.

[0079] Example 2

[0080] Please see Figures 9 to 10 Embodiment 2 is a further supplementary description of Embodiment 1. Specifically, the rotating component 62 includes a rotating motor 621, a first rotating gear 622, a second rotating gear 623, a gear chain 624, a rotating sleeve 625, a rotating rod 626, a rotating helical gear 627, and a helical gear ring 628. The rotating motor 621 is fixedly installed on the top of the sealing cover plate 3, and the output end of the rotating motor 621 is fixedly connected to the first rotating gear 622. The first rotating gear 622 is connected to the second rotating gear 623 through the gear chain 624. The second rotating gear 623 is fixedly installed on the top of the rotating sleeve 625 through a rotating shaft.

[0081] The rotating sleeve 625 penetrates the top of the sealing cover plate 3 and is rotatably connected to the sealing cover plate 3.

The rotating sleeve 625 is provided with synchronous grooves corresponding to the positions of the two synchronous bars 629.

[0082] The rotating helical gear 627 is fixedly installed at the bottom of the rotating rod 626, and the helical gear ring 628 is fixedly sleeved on the outer side of the top of the rotating frame 61. The rotating helical gear 627 is meshed with the helical gear ring 628, and the rotating rod 625 is rotatably connected to the support platform 81.

[0083] Detailed implementation: When the rotating frame 61 is driven, the rotating motor 621 runs, causing the first rotating gear 622 to rotate. At the same time, the gear chain 624 drives the second rotating gear 623 to rotate synchronously. At this time, the rotating sleeve 625 drives the rotating rod 626 to rotate synchronously through the two internal synchronous sliding grooves. The rotating helical gear 627 drives the helical gear ring 628 to rotate synchronously, which further causes the rotating frame 61 to rotate relative to the support platform 81.

[0084] Meanwhile, in this application, due to the setting of the synchronization bar 629 on the outer side of the rotating rod 626, and in conjunction with the two synchronization grooves of the rotating sleeve 625, when the rotating rod 626 moves upward or downward relative to the rotating sleeve 625, the rotating sleeve 625 still synchronously drives the rotating rod 626 to rotate.
