[0002] Seedling trays can be used to cultivate various types of plants. From the perspective of crops, they cover various vegetables, such as leafy vegetables like lettuce and spinach, and fruit vegetables like tomatoes and peppers. In the seed germination stage, plants rely on the appropriate temperature, humidity in the seedling tray, and the conditions provided by the seedling substrate to start growing. The seedling substrate not only provides physical support for the seeds but also stores and supplies the water and nutrients required for seed germination. After these vegetable seeds germinate into seedlings in the seedling tray, they are then transplanted to the field or greenhouse for subsequent growth, which can improve the yield and growth uniformity.
[0003] In the prior art, some seedling trays are usually used to cultivate various types of plants. During the cultivation process, due to the parts of the seedling tray near the edge or ventilation openings being at a relatively low temperature while the middle part is at a relatively high temperature, this temperature difference will cause inconsistent growth of the seedlings.

[0023] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figure 2 , Figure 3 and Figure 5 , an embodiment provided by the present utility model: a plant seedling tray, a chassis 1, the chassis 1 is the basic part of the entire seedling tray, and a load-bearing component for supporting the whole is fixedly connected to its bottom end. This load-bearing component includes a plurality of support legs 2, and the number of support legs 2 depends on the design requirements of the seedling tray. The plurality of support legs 2 work together to provide stable support for the seedling tray. The bottom ends of the support legs 2 are fixedly connected with suction cups 3, and these suction cups 3 can tightly adsorb on the placement plane by using the negative pressure principle, making the seedling tray more stable during placement and not easy to shake or tip over. The top ends of the plurality of support legs 2 are firmly fixedly connected to the bottom end of the chassis 1, thus constructing a stable bottom support structure. A water delivery hole 4 is opened at the left end of the rear side of the chassis 1, and the existence of the water delivery hole 4 is to realize specific water flow functions in the seedling tray. For example, when performing irrigation or drainage-related operations, it can serve as a channel for water to flow in and out. A water chute 5 is opened at the inner bottom end of the chassis 1;
[0025] The water chute 5 is an important structure inside the chassis 1 for guiding the flow direction of water. It can make the water flow along a predetermined path to meet the water requirements during the seedling cultivation process. Inside the chassis 1, there is also a fixed connection with a circulation pipe 6. At the top of the chassis 1, there is a fixed connection with a support plate 7. The outer bottom end of the support plate 7 is slidably connected to the inner top end of the chassis 1. Multiple cell grooves 8 are opened at the top of the support plate 7. The cell grooves 8 are an important part of the seedling tray, and their quantity and size can be designed according to the types and requirements of the seedlings. Inside the cell grooves 8, there is a slidable connection with a container 9. The container 9 is the place directly used for cultivating plant seedlings. At the outer top end of the container 9, there is a fixed connection with a support ring 10. The support ring 10 provides an additional support structure for the container 9, making the placement of the container 9 in the cell grooves 8 more stable;
[0026] At the bottom end of the support ring 10, there is a fixed connection with a limiting rod 11. The outer part of the limiting rod 11 is slidably connected to the inner top end of the support plate 7. The limiting rod 11 and the support ring 10 work together. They can not only prevent the container 9 from slipping out of the cell grooves 8, but also, during the daily use of the container 9, limit the moving direction of the container 9, ensuring that the container 9 is always in a proper position, which is beneficial to the normal growth of plant seedlings. Multiple ventilation holes 12 are opened at the outer bottom end of the support plate 7. The setting of the ventilation holes 12 is crucial for the air circulation inside the seedling tray. They can allow fresh air to enter the inside of the seedling tray and at the same time discharge the waste gas generated by the plant's respiration, providing sufficient oxygen for the growth of the seedlings. In addition, multiple through holes 13 are opened at the bottom end of the support plate 7.
[0027] Refer to Figure 1 and Figure 4 , the internal structure at the four corners of the support plate 7. Inside the four corners of the support plate 7, there are fixed connections with fixed columns 14. The outer bottom end of the fixed columns 14 is slidably connected to the inner top end of the chassis 1. This slidable connection allows the fixed columns 14 to have a certain range of movement at the top of the chassis 1, which has special significance in the structural design of the seedling tray. For example, in some cases such as assembly or disassembly, it can facilitate the adjustment of the relative position between the support plate 7 and the chassis 1. Inside the top inner wall of the fixed column 14, there is a slidable connection with a sliding rod 15. The sliding rod 15 can perform up and down sliding operations inside the top inner wall of the fixed column 14. The outer part of the engaging ball 20 is in contact with the inner bottom end of the sliding rod 15. On the outer part of the sliding rod 15, there is a strong spring 16. The other end of the strong spring 16 is fixedly connected to the inner bottom end of the fixed column 14. The strong spring 16 plays a key role of elastic support and reset in this structure. There is also a fixed connection with a limiting disk 17 on the outer part of the sliding rod 15. One end of the strong spring 16 is fixedly connected to the bottom end of the limiting disk 17;
[0028] The limit plate 17 can limit the extension and contraction range of the strong spring 16, and play an auxiliary positioning role during the sliding process of the sliding rod 15. A movable groove 18 is provided on the outside of the sliding rod 15. The movable groove 18 is a special structural design, which is related to the movement trajectory of the locking ball 20. The bottom end of the sliding rod 15 is fixedly connected with a baffle 19, and the outside of the baffle 19 is slidably connected to the inside of the bottom end of the fixed column 14. The baffle 19 can prevent the sliding rod 15 from slipping off the bottom end of the fixed column 14, and also limit the sliding stroke of the sliding rod 15 to a certain extent. The outer bottom end of the fixed column 14 is movably connected with a locking ball 20, and the outside of the locking ball 20 is in contact with the inside of the movable groove 18. When it is necessary to clean the water trough 5 opened in the chassis 1, by pressing the sliding rod 15, during the pressing process, the sliding rod 15 slides upward, because the locking ball 20 is in contact with the inside of the bottom end of the sliding rod 15;
[0029] The upward sliding of the sliding rod 15 causes the engaging ball 20 to fall off from the interior of the fixed column 14 and then move into the interior of the movable groove 18. Because the outer portion of the engaging ball 20 was previously engaged with the inner portion of the top of the chassis 1, when the engaging ball 20 moves into the interior of the movable groove 18, the engaging state between the support plate 7 and the chassis 1 is released, and the support plate 7 is separated from the chassis 1. This separation greatly facilitates the cleaning of the water trough 5 provided in the chassis 1, thereby reducing the difficulty of maintenance. The staff can more thoroughly remove the dirt and impurities accumulated in the water trough 5, ensuring the normal function of the water trough 5 and thus ensuring the normal operation of the entire seedling tray.
[0030] Working Principle: During the seedling raising process, when the temperature of the seedling tray needs to be adjusted, the heating element activates. It is connected to a heating tube located outside the multiple cells 8. Hot air generated by the heating element enters the heating tube, flows along the heating tube, and passes through the exterior of each cell 8. Because each cell 8 is surrounded by an independent heating tube, each cell is provided with a relatively independent and uniform heat supply. This effectively avoids temperature variations caused by the different positions of the cells in the seedling tray, ensuring a more uniform temperature across the cells within the tray.
[0031] When it is necessary to clean the water chute 5 inside the chassis 1, the staff manually presses the sliding rod 15. The sliding rod 15 slides upward on the inner wall of the top end of the fixed column 14, and the upward sliding of the sliding rod 15 drives the limiting disc 17 outside it to move upward together. When the limiting disc 17 moves upward, it applies pressure to the strong spring 16. One end of the strong spring 16 is fixed to the bottom end of the limiting disc 17, and the other end is fixed to the inner bottom end of the fixed column 14. The strong spring 16 begins to contract under the extrusion of the limiting disc 17. At the same time, the upward sliding of the sliding rod 15 causes the engaging ball 20 that was originally in contact with the inner part of the bottom end of the sliding rod 15 to move. The engaging ball 20 is driven by the sliding rod 15 to fall off from the inside of the fixed column 14 and move into the movable groove 18 outside the sliding rod 15. Since the engaging ball 20 was previously engaged with the inner part of the top end of the chassis 1, after the engaging ball 20 moves into the movable groove 18, the engagement state between the support plate 7 and the chassis 1 is released, causing the support plate 7 to separate from the chassis 1. This provides convenience for cleaning the water chute 5 opened inside the chassis 1, enabling the staff to more thoroughly remove the dirt, impurities, etc. accumulated in the water chute 5, thereby reducing the difficulty of equipment maintenance.
[0032] The chassis 1 is supported by a plurality of support legs 2. The top ends of the support legs 2 are fixedly connected to the bottom end of the chassis 1, and the bottom ends of the support legs 2 are fixedly connected with suction cups 3. The entire seedling tray can be stably placed through the suction cups 3. A water delivery hole 4 is opened at the left end of the rear side of the chassis 1, a water chute 5 is opened at the inner bottom end thereof, and a circulation pipe 6 is also fixedly connected inside. These structures jointly participate in the related functions such as the water flow circulation inside the chassis 1. The outer bottom end of the support plate 7 is slidably connected to the inner part of the top end of the chassis 1. A plurality of cell grooves 8 are opened at the top end of the support plate 7, and a container 9 is slidably connected inside the cell grooves 8. The support ring 10 at the outer top end of the container 9 and the limiting rod 11 at its bottom end cooperate. The limiting rod 11 slides inside the top end of the support plate 7 to stably place the container 9 in the cell grooves 8. In addition, a plurality of ventilation holes 12 and through holes 13 are opened at the outer bottom end of the support plate 7, and these holes contribute to functions such as air circulation.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
