Description

Technical Field

[0001] This utility model relates to the field of seedling tray technology, and in particular to a seedling tray structure that facilitates the injection of nutrient substrate. Background Technology

[0002] Rice seedling trays are specialized equipment used in the rice seedling raising process. They are mainly used to provide a standardized growth environment for rice seedlings and to facilitate mechanized transplanting.

[0003] In standardized seedling raising systems, maintaining healthy seedling growth requires periodic replenishment of nutrients, with the application of nutrient substrate being particularly crucial. However, in practice, it has been found that traditional drip irrigation methods suffer from low nutrient transport efficiency due to the coupling effect between the fluid characteristics of liquid fertilizers and the thickness of the seedling substrate layer. Specifically, fertilizer solutions struggle to accurately reach the root distribution area, requiring repeated additions to maintain an effective nutrient concentration in the substrate layer. This results in a complex nutrient regulation process. Such high-frequency manual intervention not only significantly increases the labor load of seedling raising operations but may also lead to decreased seedling growth uniformity due to differences in operational standards, creating a potential risk point for seedling quality control. Utility Model Content

[0004] The purpose of this invention is to address the problem of low nutrient delivery efficiency in traditional drip irrigation methods. Specifically, fertilizer solutions are difficult to accurately reach the root zone, requiring repeated additions to maintain an effective nutrient concentration in the substrate layer. This results in a complex nutrient regulation process. Such frequent manual intervention not only significantly increases the labor load of seedling cultivation but also may lead to decreased seedling growth uniformity due to differences in operational standards, creating a potential risk point for seedling quality control.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seedling tray structure for easy injection of nutrient substrate, comprising: a base plate, on which a seedling platform is mounted; multiple sets of grids are arranged in an alternating pattern within the seedling platform, the alternating areas of the grids forming planting units for placing soil and seedlings, each planting unit having through holes, and each planting unit having a percolation pipe installed inside, the percolation pipe being hollow, and having multiple evenly distributed percolation heads on the end face of the percolation pipe facing the middle of the planting unit. By setting a percolation pipe in each planting unit, nutrient substrate liquid can be injected into the percolation pipe during use, and the nutrient substrate can be slowly released into soil layers at different depths through the percolation pipe, allowing for a more reasonable distribution of the nutrient substrate in the soil, making the injection of nutrient substrate more efficient, reducing the number of times nutrient substrate needs to be added manually, and making the injection of nutrient substrate more convenient.

[0006] In a preferred embodiment, the output diameter of the percolation head gradually increases from bottom to top. By setting different heights and different hole sizes, the amount of nutrient substrate solution percolating at each layer is made as even as possible, thereby making the nutrient substrate solution more uniformly distributed at different soil depths and providing a more stable growth environment for seedlings.

[0007] In a preferred embodiment, support plates are fixedly connected to the four corners of the chassis, and the four lower corners of the seedling platform abut against the support plates. By setting the support plates, a gap is left between the seedling platform and the chassis, allowing water and seepage liquid to temporarily remain in the gap between the seedling platform and the chassis, preventing contamination of the seedling platform surface.

[0008] In a preferred embodiment, the ends of the seepage heads are all wrapped with mesh, with a mesh size of ≤ 100 mesh. This prevents soil particles, algae, and other impurities from clogging the pores.

[0009] In a preferred embodiment, the top of the seepage tube is hinged with a cap, which can slow down the natural evaporation of the nutrient substrate inside the seepage tube.

[0010] In a preferred embodiment, the top of the cap is provided with a through hole. This through hole allows atmospheric pressure inside the seepage tube to communicate with the outside, preventing backflow and blockage of the seepage head.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention features an infiltration pipe in each planting unit. During use, nutrient substrate solution is injected into the infiltration pipe, and the nutrient substrate is slowly released into soil layers at different depths through the infiltration pipe. This allows the nutrient substrate to be distributed more rationally in the soil, making the injection of nutrient substrate more efficient, reducing the number of times nutrient substrate needs to be added manually, and making the injection of nutrient substrate more convenient.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a seedling tray structure that facilitates the injection of nutrient substrate, comprising: a base plate 2, on which a seedling platform 1 is provided; multiple sets of grids 3 are arranged in an alternating manner inside the seedling platform 1, the alternating areas of the grids 3 forming planting units for placing soil and seedlings, the planting unit is provided with through holes 6, and each planting unit is equipped with a drainage pipe 4, the drainage pipe 4 is hollow inside, and multiple evenly distributed drainage heads 8 are provided on the drainage pipe 4 facing the middle end face of the planting unit;

[0021] By installing an infiltration pipe 4 in each planting unit, nutrient substrate liquid can be injected into the infiltration pipe 4 during use. The nutrient substrate is then slowly released into soil layers at different depths through the infiltration pipe 4, which allows the nutrient substrate to be distributed more reasonably in the soil. This makes the injection of nutrient substrate more efficient, reduces the number of times nutrient substrate needs to be added manually, and makes the injection of nutrient substrate more convenient.

[0022] like Figure 1-4 As shown, the diameter of the nutrient substrate solution output from the bottom to the top of the percolation head 8 gradually increases. By setting different heights and different hole sizes, the amount of nutrient substrate solution percolating at each layer is made as even as possible, so that the nutrient substrate solution is more evenly distributed at different soil depths, providing a more stable growth environment for the seedlings.

[0023] like Figure 1-4 As shown, support plates 7 are fixedly connected to the four corners of the base 2, and the four corners of the lower end of the seedling platform 1 abut against the support plates 7. By setting the support plates 7, a gap is left between the seedling platform 1 and the base 2, so that water and seepage liquid can be temporarily stored in the gap between the seedling platform 1 and the base 2, preventing contamination of the seedling platform surface.

[0024] like Figure 1-4 As shown, the ends of the seepage head 8 are all wrapped with a mesh 9 with a mesh size of ≤50 mesh; to prevent soil particles, algae and other impurities from clogging the holes.

[0025] like Figure 1-4 As shown, a cap 10 is hinged to the top of the seepage pipe 4. The cap 10 can slow down the natural evaporation of the nutrient substrate inside the seepage pipe 4.

[0026] like Figure 1-4 As shown, a through hole is provided at the top of the cap 10; by providing a through hole, the atmospheric pressure inside the seepage pipe 4 can be connected with the outside, preventing backflow that could cause blockage of the seepage head 8.

[0027] Working principle: When adding nutrient substrate, liquid nutrient substrate is directly added into the percolation pipe 4. The nutrient substrate is slowly percolated through multiple percolation heads 8. According to Bernoulli's equation, the output diameter of the percolation heads 8 is gradually increased from bottom to top to ensure that the mass of liquid nutrient substrate percolated by each layer of the percolation head 8 per unit time is as uniform as possible. However, as the height decreases, the liquid nutrient in the upper layer will not be output, thus forming a pyramid-shaped output curve. This can match the absorption and utilization rate of plant root nutrient acquisition levels, thereby making the nutrient substrate more rationally distributed in the soil, making the injection of nutrient substrate more efficient, reducing the number of times nutrient substrate is added manually, and making the injection of nutrient substrate more convenient.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
