Description

Technical Field

[0001] This utility model relates to the field of ginger cultivation equipment, and in particular to a high-yield, disease-resistant, high-quality ginger cultivation and fertilization device. Background Technology

[0002] Traditional ginger cultivation fertilization devices mostly use single-pipe direct application or mechanical trenching and spreading methods, resulting in chaotic fertilization layers. Single fertilization depth leads to insufficient nutrition on the shallow leaves and fertilizer accumulation and root burn in the deep root zone. Some solutions also use multi-stage fertilization, but they rely on manual valve adjustment for layering, which makes operation complicated and limits precision, resulting in low overall fertilization efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-yield, disease-resistant, and high-quality ginger cultivation and fertilization device. The technical problem to be solved by the present invention is: how to optimize the growth environment of ginger and improve the efficiency of fertilization by using a graded fertilization strategy.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-yield, disease-resistant, high-quality ginger cultivation and fertilization device, comprising an outer tube and an inner tube, with an annular gap between the outer tube and the inner tube, and a sealing end cap provided at the top of the annular gap, the end cap being connected to the outer tube, the end cap connecting a pump body filled with liquid fertilizer to the hollow inner tube, the inner tube having several internal nozzles, each internal nozzle having a guide plate elastically hinged thereto, the inner wall surface of the guide plate being flush with the outer wall surface of the internal nozzle, wherein the elastic force on the guide plate near the end cap is less than the elastic force on the guide plate far from the end cap.

[0005] In a preferred embodiment, the width of the annular gap is 3-5 mm.

[0006] In a preferred embodiment, each external nozzle is equipped with a one-way valve.

[0007] In a preferred embodiment, an atomizing nozzle is installed at the outlet of a one-way valve located inside the upper external nozzle.

[0008] In a preferred embodiment, the external nozzle is spirally formed on the side wall of the outer tube.

[0009] In a preferred embodiment, a plug is fixed to the end cap, the outer wall of the plug is fitted to the inner wall of the inner tube, and the plug is connected to the output end of the pump body, which is connected to liquid fertilizer, through a flexible tube.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] Through the constraint of elastic force, the liquid fertilizer sprayed from the outer tube located in the soil has multiple functions. The liquid fertilizer sprayed from the outer nozzle above the soil acts on the leaves of ginger, with a wider range of action. The liquid fertilizer sprayed from the outer nozzle below the soil acts on the roots of ginger. Due to sufficient pressure, it has stronger penetration and will not burn the roots due to excessive fertilizer in some areas. This allows the liquid fertilizer to provide sufficient nutrients for root growth evenly. Attached Figure Description

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] Example

[0020] like Figures 1-4 The fertilization device enables differential fertilization of the shallow and deep layers of the soil. The shallow layer is for fertilizing the ginger leaves, while the deep layer is for fertilizing the ginger roots.

[0021] The system includes an outer tube 11, an inner tube 12, an end cap 13, an outer nozzle 14, an inner nozzle 15, and a guide plate 16. The inner tube 12 is threadedly connected to the outer tube 11, with an annular gap between them. The top of the outer tube 11 is threadedly connected to the end cap 13 to seal the annular gap. The inner tube 12 is also hollow, with a plug at the center of the end cap 13 to fit against the inner wall of the inner tube 12. A pump body is connected to the plug, and the pump body can deliver the mixed liquid fertilizer into the inner tube 12 through a flexible pipe. The method of delivering the liquid fertilizer is existing technology and will not be described in detail.

[0022] The inner tube 12 has several internal nozzles 15, and each nozzle 15 is elastically hinged with a guide plate 16. Without external interference, the guide plate 16 naturally closes onto the nozzle 15, creating a sealed space inside the inner tube 12. When the pump delivers liquid fertilizer into the inner tube 12 and the hydraulic pressure reaches a certain level, the guide plate 16 can be driven to open under sufficient pressure, connecting the spaces inside and outside the inner tube 12.

[0023] Specifically, the deflector plate 16 is connected to the side of the inner nozzle 15 via a spring hinge.

[0024] Defining the tip of the outer tube 11 as the bottom and the direction of the end cap 13 as the top, the elastic force of the spring on the guide plate 16 gradually decreases from bottom to top. That is, the guide plate 16 near the end cap 13 experiences a lower elastic force, and a small pressure is sufficient to open the guide plate 16; the guide plate 16 near the tip of the outer tube 11 experiences a higher elastic force, requiring a larger pressure to open the guide plate 16. Because the guide plate 16 is designed to fit the outer side of the inner tube 12, its inner surface is arc-shaped. Therefore, the liquid fertilizer sprayed from the inner nozzle 15 moves along the arc-shaped guide plate 16 into the annular gap, carrying more energy.

[0025] The outer pipe 11 has several external nozzles 14. After passing through the gaps, the liquid fertilizer can be sprayed out of the external nozzles 14 to fertilize the soil.

[0026] It should be noted that because the gap is small, usually 3-5mm, the liquid fertilizer sprayed from the inner tube 12 will pass through the gap in a turbulent manner and be sprayed out from the corresponding outer nozzle 14, instead of settling within the gap.

[0027] Each external nozzle 14 of the outer pipe 11 is equipped with a one-way valve. Since there are many types of one-way valves and their installation methods are flexible, they will not be described in detail in this embodiment.

[0028] For example, a plastic ball check valve can be used. The base of the check valve has an annular groove. The groove is locked on the side of the external nozzle 14, which can stably connect the plastic ball check valve to the external nozzle 14, preventing soil and dust from the external environment from entering the gap. Moreover, the plastic ball check valve is low in cost.

[0029] The liquid fertilizer ejected from the external nozzle 14 enters the corresponding soil layer laterally. The external pipe 11, as a rigid separator, can effectively block the longitudinal flow of liquid fertilizer between different soil layers.

[0030] Preferably, the external nozzle 14 is spirally formed in the side wall of the external tube 11, and can be a single spiral structure or a multi-spiral structure. The spiral structure design creates multi-dimensional fertilization angles in the horizontal / vertical directions, avoiding direct application through a single tube.

[0031] Preferably, the orifice diameter of the external nozzle 14 gradually decreases from top to bottom. Therefore, atomizing nozzles with more holes can be installed at the outlet of the one-way valve on the upper external nozzle 14, allowing the ginger leaves to be fertilized by atomization. Since the orifice diameter is smaller at the bottom of the external nozzle 14, a single-beam nozzle with fewer holes is usually installed at the outlet of the one-way valve, allowing the liquid fertilizer to penetrate into the soil gaps further under a certain pressure.

[0032] The working principle of the above structure is as follows:

[0033] The outer tube 11 is inserted into the soil where ginger is planted. By controlling the pump, pressurized liquid fertilizer is injected into the inner tube 12 through a hose. As the pressure gradually increases, the guide plate 16 at the top of the inner tube 12 gradually opens, but not completely. The liquid fertilizer passes through the annular gap and is then forced outward from the corresponding nozzle 14. Subsequently, the guide plate 16 at the bottom of the inner tube 12 also gradually opens, while the guide plate 16 at the top of the inner tube 12 fully opens, ensuring that the amount of liquid fertilizer sprayed from the top of the outer tube 11 is always greater than that sprayed from the bottom. This achieves the goal of applying more fertilizer to the leaves and less fertilizer to the roots.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
