Description

Technical Field

[0001] This utility model belongs to the field of fruit tree planting technology, specifically, it relates to a fruit tree fixed-point drip irrigation and fertilization device. Background Technology

[0002] Fruit tree drip irrigation and fertilization systems are a modern agricultural technology designed to improve fruit tree growth efficiency and fruit quality through precise irrigation. Consumers are increasingly demanding higher standards of food quality and safety. Precise fertilization and irrigation can improve fruit quality, reduce fertilizer residues, and meet the health needs of modern consumers.

[0003] Existing fixed-point fertilization devices typically use liquid bags hung around fruit trees. While this simplifies the fertilization process to some extent, it also has several significant drawbacks. First, liquid bag fertilization devices cannot dynamically adjust the amount of fertilizer applied based on the fruit tree's growth stage and seasonal needs. This can lead to the fruit trees receiving too much or too little fertilizer, affecting their growth and fruit quality. Second, the solution in the liquid bag cannot self-regulate once opened; if not collected promptly, the entire solution will drip out, resulting in significant waste and soil pollution. Furthermore, the liquid bags cannot be reused, further contributing to waste.

[0004] In summary, existing fixed-point fertilization devices have the problems of not being able to be reused and not being able to flexibly adjust the amount of fertilizer applied. Utility Model Content

[0005] In view of this, the present invention provides a fruit tree fixed-point drip irrigation fertilization device, which can solve the problems of existing fixed-point fertilization devices that cannot be reused and cannot flexibly adjust the amount of fertilizer.

[0036] like Figure 1-2 The image shows an embodiment of a fruit tree drip irrigation fertilization device provided by this utility model. In this embodiment, it includes a fertilizer tank 10, a guide pipe 20, an annular water pipe 30, a moving component 40, drip irrigation heads 50, and a rebound component 70. The fertilizer tank 10 is used to store liquid fertilizer nutrients. A guide pipe 20 is provided below the fertilizer tank 10 and is connected to the fertilizer tank 10. The guide pipe 20 includes an inner pipe 21, an outer pipe 22, and an insert 23. The inner pipe 21 and the outer pipe 22 are used to drain the fertilizer water in the fertilizer tank 10. The insert 23 is used to fix the fertilization device. An annular water pipe 30 is fixedly connected to the outside of the outer pipe 22. Multiple drip irrigation heads 50 are evenly arranged on the annular water pipe 30. A moving component 40 is fixedly connected to the inner pipe 21. The moving component 40 is used to control the drip irrigation time of the drip irrigation heads 50. A rebound component 70 is provided inside the inner pipe 21 and is used to assist the movement of the moving component 40.

[0037] In the above technical solution, the insert 23 is fixedly connected to the outer tube 22, the outer tube 22 is sleeved on the outside of the inner tube 21, the outer tube 22 is slidably connected to the inner tube 21, the insert 23 is a conical structure, and a wing plate 60 is provided on the outside of the insert 23. The wing plate 60 is a spiral structure.

[0038] Furthermore, in the above technical solution, the bottom of the inner tube 21 is evenly arranged with multiple drainage holes 211, the bottom of the outer tube 22 is provided with an inner cavity 221, the drainage holes 211 are used to guide the liquid fertilizer in the fertilizer box 10 into the inner cavity 221, the inner cavity 221 is provided with a rebound component 70, and the annular water pipe 30 is connected to the inner cavity 221.

[0039] Furthermore, in the above technical solution, the rebound assembly 70 includes an inner cylinder 71, an outer cylinder 72, and a spring 73. The outer cylinder 72 is sleeved outside the inner cylinder 71 and is slidably connected to the inner cylinder 71. A protrusion is provided on the outer wall of the inner cylinder 71, and the protrusion is adapted to the sliding groove on the inner wall of the outer cylinder 72. The outer cylinder 72 is located above the inner cylinder 71 and is fixedly connected to the lower bottom surface of the inner tube 21. The lower bottom surface of the inner cylinder 71 is fixedly connected to the upper top surface of the insert 23. A spring 73 is provided between the inner cylinder 71 and the outer cylinder 72.

[0040] Furthermore, in the above technical solution, the moving component 40 includes a pedal 41, a first connecting rod 42, and a second connecting rod 43. One end of the first connecting rod 42 is fixedly connected to the inner tube 21, and the other end of the first connecting rod 42 is fixedly connected to one end of the second connecting rod 43. The other end of the second connecting rod 43 is rotatably connected to the pedal 41 via a pin.

[0041] Furthermore, in the above technical solution, the first connecting rod 42 is perpendicular to the inner tube 21, and the second connecting rod 43 is perpendicular to the first connecting rod 42.

[0042] Furthermore, in the above technical solution, the pedal 41 has an arc-shaped structure, and the pedal 41 fits against the outer wall of the outer tube 22.

[0043] Furthermore, in the above technical solution, multiple isolation strips 44 are evenly arranged on the side wall of the outer tube 22. The isolation strips 44 have an arc-shaped structure, and the distance between two adjacent isolation strips 44 is the same as the thickness of the pedal 41.

[0044] Furthermore, in the above technical solution, the diameter of the annular water pipe 30 is twice the length of the diameter of the outer pipe 22, and multiple connecting pipes are provided between the annular water pipe 30 and the outer pipe 22, and the connecting pipes are straight.

[0045] Furthermore, in the above technical solution, the fertilizer box 10 is made of transparent high-strength plastic, and the fertilizer box 10 is marked with graduations.

[0046] In use, insert the insert 23 into the root zone of the fruit tree. The outer wing plate 60 of the insert 23 rotates into the soil, generating significant friction with the soil and reducing the possibility of the fertilizer applicator tipping over accidentally. Pour the liquid fertilizer into the inlet of the fertilizer tank 10 and then seal the inlet with the lid. At this time, the liquid fertilizer flows along the inner tube 21.

[0047] Since the inner wall of the outer tube 22 is in contact with the outer wall of the inner tube 21, the fertilizer solution cannot flow into the inner cavity 221 through the drainage hole 211. At this time, the fertilizer application device can store the fertilizer solution for a long time and maintain a state of storage without spillage.

[0048] When drip irrigation is needed, the pedal 41 is rotated out from between the separator strips 44 and pressed down, causing the first connecting rod 42 and the second connecting rod 43 to move downwards. This causes the inner tube 21 to slide inside the outer tube 22. With the inner tube 21 no longer obstructed by the inner wall of the outer tube 22, some of the drainage holes 211 are exposed in the inner cavity 221. Fertilizer solution flows from the drainage holes 211 into the inner cavity 221, and then into the annular water pipe 30 for irrigation through the drip head 50. During the movement of the moving component 40, the outer cylinder 72 slides relative to the inner cylinder 71, compressing the internal spring 73. Because there are graduations on the side wall of the outer tube 22, when adjusted to the appropriate position, the pedal 41 is rotated back into the corresponding separator strips 44.

[0049] The amount of fertilizer water entering the inner cavity 221 is controlled by adjusting the sliding distance of the inner tube 21 within the outer tube 22. The greater the sliding distance, the more liquid enters the inner cavity 221 per unit time. When the liquid level in the fertilizer tank 10 drops to a predetermined height, the moving component 40 is reset, at which point the fertilizer liquid cannot flow out of the drainage hole 211. The fertilizer water entering the inner cavity 221 is dripped to the area around the fruit trees through the drip irrigation head 50.

[0050] Specifically, the principle of this utility model is as follows: During use, the insert 23 is inserted into the root zone of the fruit tree. The outer wing plate 60 of the insert 23 rotates into the soil, generating significant friction with the soil, which reduces the possibility of the fertilizer applicator accidentally tipping over. Liquid fertilizer is poured into the fertilizer tank 10 through the inlet, and then the inlet is sealed with a lid. At this time, the liquid fertilizer flows along the inner tube 21.

[0051] Since the inner wall of the outer tube 22 is in contact with the outer wall of the inner tube 21, the fertilizer solution cannot flow into the inner cavity 221 through the drainage hole 211. At this time, the fertilizer application device can store the fertilizer solution for a long time and maintain a state of storage without spillage.

[0052] When drip irrigation is needed, the pedal 41 is rotated out from between the separator strips 44 and pressed down, causing the first connecting rod 42 and the second connecting rod 43 to move downwards. This causes the inner tube 21 to slide inside the outer tube 22. With the inner tube 21 no longer obstructed by the inner wall of the outer tube 22, some of the drainage holes 211 are exposed in the inner cavity 221. Fertilizer solution flows from the drainage holes 211 into the inner cavity 221, and then into the annular water pipe 30 for irrigation through the drip head 50. During the movement of the moving component 40, the outer cylinder 72 slides relative to the inner cylinder 71, compressing the internal spring 73. Because there are graduations on the side wall of the outer tube 22, when adjusted to the appropriate position, the pedal 41 is rotated back into the corresponding separator strips 44.

[0053] The amount of fertilizer water entering the inner cavity 221 is controlled by adjusting the sliding distance of the inner tube 21 within the outer tube 22. The greater the sliding distance, the more liquid enters the inner cavity 221 per unit time. When the liquid level in the fertilizer tank 10 drops to a predetermined height, the moving component 40 is reset, at which point the fertilizer liquid cannot flow out of the drainage hole 211. The fertilizer water entering the inner cavity 221 is dripped to the area around the fruit trees through the drip irrigation head 50.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
