Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, and in particular to a layered multi-plant pre-cultivation rack. Background Technology

[0002] In modern agricultural cultivation, tiered plant cultivation racks are widely used due to their high space utilization and high planting density. However, in practical applications, existing tiered plant cultivation racks have significant drawbacks that cannot be ignored. Because of the structural design of the cultivation trays, water easily drips directly onto the lower layers of plants through the bottom holes. This phenomenon can lead to several adverse consequences: firstly, the dripping water may carry pathogens and impurities from the upper layers, causing cross-contamination between different layers, increasing the risk of plant diseases and affecting healthy plant growth; secondly, the continuous dripping of water onto the lower layers creates an overly wet environment, easily leading to root rot, damaging the normal physiological functions of the root system, and thus hindering the growth and development of the lower layers, reducing overall cultivation efficiency and yield.

[0020] Example 1

[0021] Please see Figure 1-4 A multi-plant pre-cultivation rack with tiers, comprising at least four support rods 10 and cultivation layers.

[0022] Specifically, the support rod 10 is made of high-strength aluminum alloy and has a square structure. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which can ensure the stability and durability of the main frame. The support rod 10 has a sliding groove 11 on its side, which adjusts the distance between adjacent cultivation layers by cooperating with the slider 31. The cultivation layer is installed between the support rods 10 for plant cultivation. The cultivation layer includes a cultivation tray 30, which is made of food-grade plastic and is square in shape. The bottom of the cultivation tray 30 has multiple sets of ventilation holes 33 evenly distributed to facilitate the drainage of excess water and prevent water accumulation and rot of plant roots. A support net 34 is placed inside the cultivation tray 30. The support net 34 is made of metal (with protection against corrosion and rust) and is used to support plant seedlings and cultivation substrate while ensuring good air permeability. Two parallel sliders 31 are fixedly connected to the outer walls on both sides of the cultivation tray 30. The sliders 31 are slidably connected in the sliding groove 11. The distance between adjacent cultivation layers is adjusted by sliding the sliders 31 up and down in the sliding groove 11.

[0023] The bottom of the support rod 10 can also be fitted with self-locking casters, making it easy to move and fix the pre-training frame in different locations.

[0024] An adjustment component 20 is provided between adjacent cultivation trays 30 to adjust the vertical distance between them and to keep the cultivation trays 30 in a fixed position after adjustment. The adjustment component 20 includes a sleeve 21 and an adjustment rod 22. The sleeve 21 is fixedly connected to the top of the cultivation tray 30, and the adjustment rod 22 is slidably fitted inside the sleeve 21. The top of the adjustment rod 22 is fixedly connected to the bottom of the cultivation tray 30 adjacent to the cultivation tray 30 with the sleeve 21 installed (taking the bottommost cultivation tray 30 as an example). Limiting holes are provided on both the sleeve 21 and the adjustment rod 22. The adjustment rod 22 can be limited and fixed inside the sleeve 21 by inserting a pin. Through the sliding cooperation between the sliding groove on the side wall of the support rod and the slider of the cultivation tray, combined with the multiple limiting holes of the sleeve-adjustment rod assembly, the vertical spacing between adjacent cultivation layers can be adjusted to ensure the growth of different types of plants at different growth stages.

[0025] The bottom cultivation layer serves as the base, and the upper two cultivation layers can be adjusted by adjusting component 20 to facilitate plant growth.

[0026] Both the sleeve 21 and the adjusting rod 22 are made of high-strength aluminum alloy, which can improve the overall support strength of the adjusting assembly 20.

[0027] The four corners of the bottom of the cultivation tray 30 are fixedly connected to the mounting blocks 32, which have threaded holes. The water receiving tray 40 is detachably installed at the bottom of the cultivation tray 30 using bolts. It is used to receive water and other impurities flowing out of the cultivation tray 30, which can prevent them from falling into the cultivation tray 30 of the next layer and ensure the normal growth of the plants.

[0028] The water tray 40 is made of food-grade plastic and is cone-shaped. The cone design allows water to flow quickly to the drain outlet reserved in the center of the bottom, which is convenient for cleaning the water tray 40 later. U-shaped grooves are opened on the front and rear sides of the water tray 40 to reserve installation space for the adjustment rod 22, and will not hinder the disassembly and assembly of the water tray 40 later.

[0029] A drain outlet is provided at the center of the bottom of the water tray 40, and a removable plug is provided inside the drain outlet.

[0030] Taking oat seed pre-cultivation as an example, the seeds of different qualities are layered for cultivation. First, four high-strength aluminum alloy support rods are connected to the cultivation trays through sliders, ensuring that each layer of cultivation trays is embedded in the groove of the support rods through the sliders. The initial spacing is adjusted, and self-locking casters are installed at the bottom of the support rods. The pre-cultivation rack is moved to a greenhouse or indoor place with sufficient light (temperature controlled at 15-20℃). A conical water receiving tray is fixed to the bottom of each layer of cultivation tray with bolts, ensuring that the U-shaped groove avoids the adjusting rods. A plug is installed at the drain outlet to close the drain outlet.

[0031] Oat seeds were divided into three categories (thousand-grain weight: Category A ≥25g, Category B 20-25g, and Category C ≤20g) by wind selection or sieving, and labeled accordingly for later use;

[0032] In each layer of the cultivation tray, lay a 2cm thick layer of substrate, place a metal support mesh, and then cover with another 3cm of substrate. Evenly sow type C seeds on the surface of the substrate (in the bottommost cultivation tray), cover with a 1cm thin layer of soil, and water thoroughly (until a small amount of water accumulates in the water collection tray). Adjust the middle layer cultivation tray to 20cm above the bottom layer (by moving it upwards using the adjusting rod), and repeat the bottom layer operation. Sow type B seeds in the middle layer cultivation tray. Adjust the upper layer cultivation tray to 20cm above the middle layer, and repeat the bottom layer operation. Sow type A seeds in the upper layer cultivation tray.

[0033] During the seed growth period, ensure the necessary light, water, and other growth conditions, and regularly observe the seedling height to adjust the vertical spacing of the cultivation trays.

[0034] In actual operation of this embodiment, the pre-cultivation rack is placed outdoors or indoors (indoors, the light and temperature required for plant growth must be guaranteed). The water tray 40 is bolted to the bottom of the cultivation tray 30, the support net 34 is placed inside the cultivation tray 30, the pre-cultivation substrate (a mixture of soil and fertilizer) is poured into the cultivation tray 30, and then the pre-cultivation seeds or pre-cultivation seedlings are planted in the cultivation tray 30 and watered for cultivation. The same type of plant can be cultivated in layers according to seeds of different qualities. The growth status of the plants can be observed under the same planting environment to select or cultivate higher quality plant seedlings. During the plant growth period, the distance between adjacent cultivation trays 30 can be adjusted appropriately according to the plant growth status to ensure normal plant growth. The water tray 40 can be removed regularly for cleaning. Alternatively, the drain outlet of the water tray 40 can be connected to a drain pipe and fixed to the bottom of the water tray 40, extending outwards from the frame so that the water in the water tray 40 can be directly discharged. The water tray 40 can then be removed occasionally for cleaning.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
