Description

Technical Field

[0001] The utility model relates to the technical field of corn seedling cultivation, and more specifically, to an observation device for corn seedling raising. Background Art

[0002] Corn seedling raising refers to the germination and growth of corn seeds under specific conditions for subsequent transplantation into large fields. First, select high-quality corn seeds suitable for local climate and soil conditions to ensure that the seeds are fresh and free from pests and diseases. Secondly, prepare the seedling raising medium: use fertile, well-drained soil or special seedling raising soil, and an appropriate amount of organic fertilizer can be added to provide nutrients. Then sow the seeds: evenly scatter the seeds in a seedling tray or seedling box, and the sowing depth is generally 2-3 times the diameter of the seeds, about 1-2 cm deep. During this process, appropriate temperature and humidity need to be maintained: the suitable temperature for corn seeds to germinate is 20-25°C, keep the seedling raising medium moist but not overly wet to avoid seed rot.

[0003] During the corn seedling raising process, the seeds do not require particularly strong sunlight. Generally, in the initial stage, corn seedlings can be placed in a seedling box to control the light. When the seedling raising soil or soil is dry, irrigation is required, but the moisture of the seedling raising soil or soil needs to be controlled. Moreover, during irrigation, the impact of water may cause the surface seedling raising soil or soil to move, affecting the planting depth of corn seeds. Additionally, operational errors during the irrigation process are likely to lead to over-irrigation, causing seed rot. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0027] Please refer to Figures 1-5 , in the present utility model, an observation device for corn seedling raising includes a corn seedling raising box 1. A partition board 2 is fixedly installed inside the corn seedling raising box 1. The inside of the corn seedling raising box 1 above the partition board 2 is filled with seedling raising soil. A water adding pipe 3 is inserted through the corn seedling raising box 1. One end of the water adding pipe 3 located inside the corn seedling raising box 1 is bent at a right angle and then rotatably connected to a drip irrigation pipe 4. A leakage prevention mechanism 5 is installed inside the water adding pipe 3 and the drip irrigation pipe 4. The drip irrigation pipe 4 is in a grid shape, and uniformly distributed drip irrigation holes 6 are opened at the bottom of the drip irrigation pipe 4. A return spring 7 is fixedly installed between the water adding pipe 3 and the drip irrigation pipe 4. A pad 8 is integrally formed on the right side of the inner wall of the corn seedling raising box 1. A transparent plate 9 is embedded in the front of the corn seedling raising box 1. The bottom of the transparent plate 9 extends to the top of the partition board 2, and the top of the transparent plate 9 extends to the top of the pad 8.

[0028] In this utility model, corn seeds are placed in the seedling-raising soil on the partition plate 2 for seedling cultivation. Then, when the seedling-raising soil needs to be watered, the drip irrigation pipe 4 is turned downward. During the turning process, the gap of the leak-proof mechanism 5 will be opened, facilitating the water in the water supply pipe 3 to enter the interior of the drip irrigation pipe 4. By connecting the right side of the drip irrigation pipe 4 to the cushion block 8, it not only limits the downward turning angle of the drip irrigation pipe 4 but also prevents the drip irrigation pipe 4 from turning upward due to the elastic force of the return spring 7. The irrigation water leaks out through the drip holes 6 and drips into the interior of the seedling-raising soil. The lower height of the drip irrigation pipe 4 as close as possible to the seedling-raising soil can reduce the impact on the seedling-raising soil, avoiding the slow development or inability to develop of the exposed corn seeds. When watering is not required, the drip irrigation pipe 4 can be disengaged from the cushion block 8, and the drip irrigation pipe 4 is turned upward by the elastic force of the return spring 7, closing the gap of the leak-proof mechanism 5, avoiding waterlogging caused by water leakage due to valve operation errors. During the watering process, the watering degree of the seedling-raising soil can be visually observed through the transparent plate 9, effectively controlling the watering amount and facilitating the control of the soil humidity environment for corn planting and development.

[0029] Please refer to Figure 4 and Figure 5 , wherein: The leak-proof mechanism 5 includes two semi-circular sealing blocks 51. One semi-circular sealing block 51 is fixedly installed inside the water supply pipe 3, and the other semi-circular sealing block 51 is rotatably installed inside the water supply pipe 3, and the two semi-circular sealing blocks 51 are rotatably connected to each other. A linkage ring 52 is fixedly installed inside the drip irrigation pipe 4, a connecting rod 53 is fixedly installed on the linkage ring 52, and the other end of the connecting rod 53 is fixedly connected to the semi-circular sealing block 51 rotatably installed inside the water supply pipe 3.

[0030] In this utility model, during the rotation process of the drip irrigation pipe 4 with the pipe orifice of the water supply pipe 3 as the axis, the drip irrigation pipe 4 can drive one of its semi-circular sealing blocks 51 to rotate and move, enabling the two semi-circular sealing blocks 51 to rotate relative to each other. When the drip irrigation pipe 4 is turned downward, it means that watering work is to be carried out, and the gap between the two semi-circular sealing blocks 51 is opened, facilitating water flow. When the drip irrigation pipe 4 is turned upward to reset, it means that the watering work is over, and the gap between the two semi-circular sealing blocks 51 is closed. The structure is simple and reasonable, replacing the valve work. When adjusting the position of the drip irrigation pipe 4, the opening and closing action can be completed, improving the use efficiency and reducing the probability of misoperation at the same time.

[0031] Please refer to Figure 3 , wherein: The drip irrigation pipe 4 is composed of three or more straight pipes connected in communication, and the corn seedling-raising position is located below the gap between two adjacent straight pipes.

[0032] In this utility model, the drip irrigation pipe 4 composed of multiple straight pipes connected in communication can improve the drip irrigation uniformity of the seedling-raising soil, ensure the humidity balance of the seedling-raising soil, and facilitate the adjustment and control of the humidity of the seedling-raising soil.

[0033] Please refer to Figure 2, wherein: a clamping groove 81 is formed in the spacer block 8, and the clamping groove 81 is adapted to and used for clamping the drip irrigation pipe 4.

[0034] In the present utility model, through the clamping groove 81, the right side of the drip irrigation pipe 4 can be easily inserted, so that the drip irrigation pipe 4 is connected to the spacer block 8, and the stability of the drip irrigation pipe 4 during the drip irrigation process is maintained.

[0035] Please refer to Figure 1 and Figure 2 , wherein: the interior of the corn seedling raising box 1 is separated into a seedling raising cavity and a leakage cavity by a partition plate 2, and uniformly distributed leakage holes 21 are formed in the partition plate 2.

[0036] In the present utility model, through the leakage holes 21 and the leakage cavity, when the drip irrigation amount of the seedling raising soil is excessive, the excess water can leak into the interior of the leakage cavity through the leakage holes 21, avoiding the influence of waterlogging on the corn seeds for a long time.

[0037] Please refer to Figure 1 and Figure 2 , wherein: a receiving box 22 is slidably installed inside the corn seedling raising box 1, and the receiving box 22 is located inside the leakage cavity.

[0038] In the present utility model, through the receiving box 22, the liquid leaking into the leakage cavity can be collected, facilitating subsequent secondary utilization and reducing pollution.

[0039] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
