Description

Technical Field

[0001] The invention relates to the technical field of seedling raising trays, and in particular to a seedling raising tray structure with automatic temperature control performance. Background Art

[0002] Seedling cultivation means cultivating young seedlings. It originally means cultivating seedlings in a nursery, hotbed or greenhouse in preparation for transplanting them into the land for planting. As the saying goes, "strong seedlings mean half the harvest", it can be seen that the quality of seedling cultivation directly affects the later growth of the seedlings. Seedling cultivation is a labor-intensive, time-consuming and highly technical job. Due to the different living habits of plants, different plants can use different seedling cultivation methods.

[0003] In the prior art, seedlings are usually cultivated in a plug tray. The plug tray is a standardized one-piece pot that connects many nutrient pots into one. There are two main categories: one is made of polyethylene or polypropylene thin plates by vacuum molding, and the other is made of polystyrene foam plastic molded by injection molding. The shapes of the holes are round and square. A plug tray is connected to a dozen or even hundreds of conical small pots of the same size, which are larger on the top and smaller on the bottom. Each small pot is called a "hole", and the holes are tightly connected to each other, so as to achieve the maximum planting density.

[0004] The existing patent (Announcement No.: CN221058946U) is a seedling tray equipped with a heating mechanism. When encountering low temperature weather, there is no need to heat the entire space in the greenhouse, but the heating mechanism is used to heat the seedling tray in a targeted manner, thus avoiding energy waste.

[0005] However, there are still some problems in the actual seedling raising process:

[0006] 1. The heat conducting member in the above technical solution heats the seedling raising tray by direct contact with the seedling raising tray, which may easily lead to uneven heating of the parts and soil in direct contact with the seedling raising tray, or even overheating, thereby affecting the cultivation of seedlings;

[0007] 2. In addition, traditional plug trays are usually fixed structures, and after the seedlings are grown, they need to be extracted together with the seedling soil for easy transportation and planting. However, the soil will aggregate during the long-term cultivation process, making it difficult to remove the seedlings and soil. Therefore, the plug tray needs to be destroyed to remove the seedlings, resulting in the inability to reuse the seedling tray, and the discarded seedling tray also causes great pollution to the environment. Summary of the invention

[0008] The purpose of the present invention is to solve the problem that the plug tray in the prior art is usually a fixed structure, and after the seedlings are mature, in order to facilitate transportation and planting, they need to be extracted together with the seedling soil.

Therefore, the plug tray needs to be destroyed to remove the seedlings, resulting in the seedling tray being unable to be reused, and the discarded seedling tray also causes great pollution to the environment.

The hot air heats the air near the seedling raising plate 4, thereby keeping the soil and seeds in an environment with a suitable temperature.

[0041] Embodiment 4: Figure 5 and Figure 7 As shown, the difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that the snap-fit ​​structure 9 includes a snap-fit ​​plate 1 901, a snap-fit ​​plate 2 902, a convex strip 1 903 and a convex strip 2 904; the outer surface of the lower end of the fixing ring 3 is fixedly connected with a snap-fit ​​plate 1 901 near the four corners, and the outer surface of one side of the snap-fit ​​plate 1 901 is fixedly connected with a plurality of groups of convex strips 1 903 at equal distances from top to bottom.

[0042] A slot 910 is provided on the outer surface of the upper end of the planting box 1 at a position corresponding to the snap-fit ​​plate 1 901, and a snap-fit ​​plate 2 902 is provided inside the slot 910. A plurality of groups of convex strips 2 904 are fixedly connected at equal distances from top to bottom on one side of the outer surface of the snap-fit ​​plate 2 902 corresponding to the convex strip 1 903. During the installation of the seedling raising box 2, the snap-fit ​​plate 1 901 is made to correspond to the slot 910, and then the snap-fit ​​plate 1 901 is inserted into the slot 910.

[0043] The top of the second locking plate 902 passes through the outside of the slot 910 and is fixedly connected to the limiting block 905. A sliding groove 906 is provided on the outer surface of the upper end of the planting box 1 at a position corresponding to the limiting block 905, and the interior of the sliding groove 906 is fixedly connected to the limiting column 907. The outer surface of the limiting column 907 is slidably connected with a slider 908, and the outer surface of the limiting column 907 is provided with a spring 909, one end of the spring 909 is fixedly connected to the slider 908, and the other end is fixedly connected to the sliding groove 906, and the limiting block 905 is fixedly connected to the slider 908. In the process of the locking plate 1 901 entering the slot 910, the convex strip 2 904 on the surface of the locking plate 1 902 is repeatedly misaligned and corresponding with the convex strip 1 903 on the surface of the locking plate 1 901 under the action of the spring 909, and finally the convex strip 2 904 is misaligned and engaged with the convex strip 1 903 to ensure the stability of the seedling box 2.

[0044] The working principle and process of the present invention are as follows:

[0045] Step 1: When the seedling raising box 2 is placed separately, a certain amount of seedling raising soil is introduced between each seedling raising plate 4 and the mud retaining net 504, and then the seeds are planted in the soil. After all is completed, the seedling raising box 2 is installed inside the planting box 1, and the elastic ring 505 is located at a position close to the bottom of the support plate 503;

[0046] Step 2: During the installation of the seedling raising box 2, the snap plate 901 is aligned with the slot 910, and then the snap plate 901 is inserted into the slot 910. The convex strip 904 on the surface of the snap plate 902 is snapped with the convex strip 903 on the surface of the snap plate 901 under the action of the spring 909 to ensure the stability of the seedling raising box 2.

[0047] Step 3: When the seedling raising box 2 enters the planting box 1, the seedling raising plate 4 corresponds to the bottom plate 701, and the fixing plate 703 pushes the elastic ring 505 to move toward the top of the support plate 503 and elastically contracts. When the elastic ring 505 moves upward, the support plate 503 drives the rotating block 502 to rotate inward to slightly squeeze and fix the soil, so as to prevent the soil from being too loose and causing the water to be unable to be retained in the soil, thereby affecting the seed germination rate;

[0048] Step 4: During the seedling raising process, the heating wire 803 heats the water inside the heating chamber 12, and the heat is transferred to the heat sink 804 through the guide ring 801. The hot air heats the air near the seedling raising plate 4, thereby keeping the soil and seeds in an environment with a suitable temperature.

[0049] Step 5: When the soil needs to be hydrated, the water pump is turned on. The planting liquid in the liquid storage chamber 6 forms a mist under the action of the atomizing nozzle 704 and slowly enters the soil to humidify the soil evenly. The interval between two adjacent groups of seedling raising plates 4 can provide sufficient space for air circulation to prevent the soil, seeds or seedlings from rotting due to lack of air circulation.

[0050] Step 6. After the seedlings are raised, the seedling raising box 2 is taken out of the planting box 1. After the seedling raising plate 4 is pulled out from the fixed plate 703, the elastic ring 505 rolls outward along the support plate 503 toward the seedling raising plate 4 under the action of its own elastic force. The support plate 503 rotates toward the outside of the mud guard net 504 under its own gravity. The soil has already agglomerated during the planting process and will not scatter. A gap is formed between the mud guard net 504, the support plate 503 and the soil, providing sufficient space for the removal of the seedlings.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
