Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, and in particular to a fertilization device for seedling cultivation. Background Technology

[0002] When cultivating seedlings in forestry, fertilization is required. Generally, for convenience, fertilizer is dissolved in water and applied as a liquid fertilizer. However, this method can easily lead to excessive fertilization, resulting in a soil solution concentration that is significantly higher than the cell sap concentration of the plant's root hair cells. This causes water to flow back into the soil from the root hair cells through osmosis, causing the plant cells to lose water and wilt, leading to seedling burn. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that easily lead to excessive fertilization and seedling burn, and to propose a fertilization device for seedling cultivation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a fertilization device for seedling cultivation, including a holding box, two shoulder straps fixedly connected to the holding box, a first rigid pipe connected to the holding box, a connecting shell connected to the first rigid pipe, a connecting hose connected to the connecting shell, a second rigid pipe connected to the connecting hose, and a rotating ring connected inside the connecting shell via a rotating mechanism, the rotating ring having a through hole.

[0006] Preferably, the rotating mechanism includes a connecting block, a rotating shaft is fixedly connected to the connecting block, and a rotating block is fixedly connected to the rotating shaft.

[0007] Preferably, a connecting ear is fixedly connected to the connecting shell, a connecting rod is provided through the connecting ear, an abutment block is fixedly connected to the connecting rod, the abutment block abuts against the rotating shaft, and a spring is fixedly connected between the connecting ear and the abutment block, the spring being in a compressed state.

[0008] Preferably, the connecting shell has two markings at equal intervals around its circumference.

[0009] Preferably, the rotating ring is made of rubber material and abuts against the inner wall of the connecting shell.

[0010] The fertilization device for seedling cultivation proposed in this utility model has the following advantages: by using a rotating mechanism to drive the rotating ring to rotate, when the through hole is connected to the first rigid tube, fertilizer enters the connecting shell. Since the amount of fertilizer that the connecting shell can hold is fixed, it plays a quantitative role. When the through hole on the rotating ring is connected to the connecting hose, the liquid in the connecting shell flows out, grasps the second rigid tube, and enters the roots of the plant, which plays a quantitative role in fertilizing the plant, preventing the amount of fertilizer from being too much and avoiding the situation of burning the seedlings.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1: Refer to Figure 1-3 A fertilization device for seedling cultivation includes a holding box 1, two carrying straps 2 fixedly connected to the holding box 1, a liquid inlet on the holding box 1, and a sealing cap threaded onto the liquid inlet. The carrying straps 2 are used to carry and move the holding box 1 to apply fertilizer. A quantitative amount of water and a quantitative amount of fertilizer are mixed to form a liquid fertilizer.

[0017] A first rigid pipe 3 is connected to the holding box 1, and a connecting shell 4, made of transparent material, is connected to the first rigid pipe 3. A connecting hose 5 is connected to the connecting shell 4, and a second rigid pipe 6 is connected to the connecting hose 5. A rotating ring 9, made of rubber material, is connected to the inner wall of the connecting shell 4 via a rotating mechanism. The rotating ring 9 abuts against the inner wall of the connecting shell 4 and acts as a seal. A through hole 10 is opened on the rotating ring 9. When the rotating mechanism drives the rotating ring 9 to rotate, the through hole 10 connects with the first rigid pipe 3, and fertilizer enters the connecting shell 4. Since the connecting shell 4 can hold a fixed amount of fertilizer, it plays a quantitative role. When the through hole 10 on the rotating ring 9 connects with the connecting hose 5, the liquid in the connecting shell 4 flows out, grasps the second rigid pipe 6, and enters the roots of the plant, which plays a quantitative role in fertilizing the plant and prevents excessive fertilizer and avoids burning the seedlings.

[0018] The rotating mechanism includes a connecting block 11, a rotating shaft 8 is fixedly connected to the connecting block 11, and a rotating block 7 is fixedly connected to the rotating shaft 8. Two markings 15 are equidistantly arranged around the circumference of the connecting shell 4. One end of the rotating block 7 has a triangular structure, which serves as an indicator. When it coincides with the marking 15, it can correspond to the position of the through hole 10, so that liquid can be filled into or drained from the connecting shell 4.

[0019] Example 2: Refer to Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, a connecting ear is fixedly connected to the connecting shell 4, a connecting rod 14 is provided through the connecting ear, and an abutment block 12 is fixedly connected to the connecting rod 14. The abutment block 12 abuts against the rotating shaft 8. A spring 13 is fixedly connected between the connecting ear and the abutment block 12. The spring 13 is in a compressed state. Through the restoring force of the spring 13, the abutment block 12 will abut against the rotating shaft 8, increasing the resistance required for rotation. This is so that when the triangular structure of the rotating block 7 coincides with the mark 15, the rotating block 7 can be fixed. This avoids the situation where the rotating block 7 rotates when it is not needed, and the rotating block 7 vibrates due to the movement of people, causing the state of the through hole 10 to change.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
