Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a rice seedling tray. Background Technology

[0002] Rice is a staple food in people's lives and plays a very important role. Therefore, rice seedling cultivation is particularly important, and people's requirements for rice seedling trays are getting higher and higher. A rice seedling tray is an agricultural tool used for centralized rice seedling cultivation. Its main function is to provide a stable growth environment for rice seeds, so as to facilitate the cultivation of strong, uniform, and easy-to-transplant seedlings.

[0003] Before filling the seedling tray with seedlings, first lay seedling soil in the seedling tray. Use small tweezers or a seeder to place 1-2 pre-germinated seeds in the center of each hole. After sowing, cover the seedlings with another layer of seedling soil, and then smooth the surface layer of seedling soil by hand.

[0004] However, the applicant believes that the shortcomings are as follows: 1. Some existing seedling trays are watered on the surface, which can cause the surface soil to be washed away by the water flow or damage the semi-mature seedlings; 2. When leveling and laying the surface seedling soil, manual operation is required. Uneven force applied by hand can easily cause the surface soil to be uneven and unable to form a uniform horizontal plane, which in turn affects the consistency of seed implantation depth, resulting in uneven germination time and uneven seedling growth.

[0005] To address this issue, we propose a rice seedling tray. Utility Model Content

[0006] The purpose of this invention is to provide a rice seedling tray to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rice seedling tray, including a water storage tray, the water storage tray being configured as a hollow rectangular structure, a maintenance tray being placed in the middle of the water storage tray, the maintenance tray being configured as a hollow rectangular structure, a sponge and a seedling tray being placed in the middle of the maintenance tray, seedling holes being evenly distributed on the seedling tray, and a circular groove being opened at the lower middle position of each group of seedling holes.

[0008] Preferably, a limiting block is provided at the inner edge of the water storage pan, and a filter screen is placed at the edge of the water storage pan through the limiting block. The limiting block limits the position of the filter screen so that the filter screen is located at the upper end of the water storage pan.

[0009] Preferably, the outer area of ​​the filter screen is larger than the outer area of ​​the maintenance tray, the height of the filter screen is lower than the height of the maintenance tray, the bottom of the maintenance tray is evenly provided with seepage holes, the maintenance tray is connected to the water storage tray through the seepage holes, the filter screen is higher than the maintenance tray, which can control the water level to be lower than the filter screen, so that the seedling tray will not be damaged by excessive water, and the connected structure can make the water supply process smoother.

[0010] Preferably, U-shaped columns are fixedly installed on both the left and right sides of the upper end of the maintenance disc, and a scraper is movably connected between the two sets of U-shaped columns. The U-shaped columns limit the movement path of the scraper, control the range of movement, and improve the stability of movement.

[0011] Preferably, the sponge has grooves evenly distributed on it, and the bottom of the seedling hole contacts the groove, so that the bottom of the seedling hole can form multi-dimensional contact with the groove, increasing the contact area and optimizing water conduction.

[0012] Preferably, the sponge is placed in the maintenance tray, and the outer dimensions of the sponge are the same as the inner dimensions of the maintenance tray. This size matching achieves a tight fit, improving structural stability and functional integrity.

[0013] This utility model provides a rice seedling tray, which has the following beneficial effects:

[0014] The combination of the maintenance tray, drainage holes, and sponge enables even watering from the roots of the seedlings. The water storage tray and filter screen can also filter and collect outdoor rainwater, allowing the roots to absorb water evenly. This reduces growth imbalances and also reduces the loss of surface soil and damage to semi-mature seedlings caused by watering directly from the seedling surface.

[0015] The use of U-shaped columns and scrapers eliminates the need for manual operation in leveling and laying the surface seedling soil, reducing uneven force application and creating a uniform horizontal plane. This ensures consistent seed implantation depth, resulting in uniform germination time and balanced seedling growth. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As Figures 1 to 3 As shown, this embodiment proposes a rice seedling tray, including a water storage tray 1, which is a hollow rectangular structure. A maintenance tray 3 is placed in the middle of the water storage tray 1. The maintenance tray 3 is also a hollow rectangular structure. A sponge 7 and a seedling tray 8 are placed in the middle of the maintenance tray 3. Seedling holes 9 are evenly distributed on the seedling tray 8, and a circular groove 10 is opened at the lower middle position of each group of seedling holes 9. A limiting block is set at the inner edge of the water storage tray 1, and a filter screen 2 is placed at the edge of the water storage tray 1 through the limiting block. The outer area of ​​the filter screen 2 is larger than the outer area of ​​the maintenance tray 3, and the height of the filter screen 2 is lower than the height of the maintenance tray 3. Drainage holes 4 are evenly opened at the bottom of the maintenance tray 3, and the maintenance tray 3 is connected to the water storage tray 1 through the drainage holes 4. Grooves are evenly opened on the sponge 7, and the bottom of the seedling holes 9 contacts the grooves. The sponge 7 is movably placed in the maintenance tray 3, and the outer dimensions of the sponge 7 are the same as the inner dimensions of the maintenance tray 3.

[0025] In the above embodiment, when watering the seedlings is required, water is directly delivered from the top of the filter screen 2. The filter screen 2 filters out weeds, sand, and other debris and delivers the water to the water storage tray 1. The highest water level is the height of the top of the water storage tray 1. This height is lower than the height of the seedling tray, which prevents the seedlings from being damaged by excessive water. The water in the water storage tray 1 is delivered to the maintenance tray 3 through the seepage holes 4. The sponge 7 in the maintenance tray 3 has a large number of tiny pores. When the sponge 7 comes into contact with water, the water molecules will automatically rise and diffuse along these pores due to surface tension and adhesion, absorbing the water. The sponge 7 transfers the water to the seedling holes 9 through the circular groove 10 at the top, replenishing the water for the seedlings in the soil. After the seedlings mature, the seedling tray 8 can be removed directly.

[0026] Example 2: Figure 4 and Figure 5 As shown, based on the same concept as the above embodiment, this embodiment also proposes that: U-shaped columns 5 are fixedly installed on both the left and right sides of the upper end of the maintenance plate 3, and scraper 6 is movably connected between the two sets of U-shaped columns 5.

[0027] In the above embodiment, before filling the seedling tray 8 with seedlings, seedling soil should be laid in the seedling tray first. Use small tweezers or a seeder to place 1-2 pre-germinated seeds in the center of each hole. After sowing, cover the seedlings with another layer of seedling soil. The soil height should be slightly higher than the edge of the tray to leave room for leveling. Then, hold the scraper 6 and scrape off the excess soil along the path of the U-shaped column 5. After completion, observe whether the soil in the seedling tray is level with the edge of the tray and there is no obvious height difference. If there are any omissions, the leveling can be repeated 1-2 times to finally make the soil surface form a uniform and smooth plane.

[0028] Finally, several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may change. Second, the accompanying drawings of the embodiments disclosed in this utility model only involve structures relevant to the embodiments disclosed in this utility model. Other structures can refer to common designs. Where there is no conflict, the same embodiment and different embodiments of this utility model can be combined with each other. Finally, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
