[0001] This utility model relates to a corn seedling cultivation device, which relates to the field of corn seedling cultivation technology, and specifically to a corn seedling cultivation device. Background Technology

[0002] In modern agricultural production, corn has become an important global food, feed, and industrial raw material crop. The seedling stage, as a key process at the beginning of corn planting, has a decisive impact on seedling survival rate, growth uniformity, and later stress resistance. For example, robust seedlings can shorten the field growth period and improve resistance to diseases and pests.

[0003] Traditional seedling trays are mostly placed in a single layer, occupying a large amount of land or seedling space. In the case of large-scale seedling production, the site cost is high. At the same time, traditional multi-layer seedling devices require the installation of a support structure first, and then the laying of external drainage pipes, connecting the drainage holes of each layer of seedling trays one by one. The installation process is complicated and inefficient. Utility Model Content

[0004] This utility model provides a corn planting and seedling raising device. One purpose is to have a multi-layer connection function to solve the problem of low space utilization in traditional devices. Another purpose is to solve the problem of low installation efficiency of multi-layer devices, so as to improve installation efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A corn seedling raising device includes a seedling tray, a support module fixedly connected to the outside of the seedling holes, a drainage outlet at the bottom of the seedling holes and a filter screen above the drainage outlet, and a drainage module fixedly connected to the bottom of the drainage holes.

[0006] A further improvement of the present invention is that the support module includes two flow guide support frames and two support frames. A flow guide folding frame is rotatably connected to the bottom of each of the two flow guide support frames, and a folding frame is rotatably connected to the bottom of each of the two support frames. A limiting seat is fixedly connected to the outer side of each flow guide folding frame and the folding frame.

[0007] A further improvement of this utility model is that: a connecting seat is fixedly connected to the top of the flow guide support frame and the support frame, and the four connecting seats are fixedly connected to the seedling tray. A sealing ring is fixedly connected inside the connecting seat, and a float ball is provided inside the connecting seat connected to the flow guide support frame, and a limiting seat II is fixedly connected above the float ball.

[0008] A further improvement of this utility model is that: the seedling tray is fixedly connected to a storage rack on the inner side of the two folding frames and the two flow guiding folding frames, and the outer side of the two storage racks is provided with a sliding groove and is slidably connected to the limiting seat on the outer side of the storage rack. The storage rack is slidably connected to a sliding lock on the outer side of the sliding groove.

[0009] A further improvement of the present invention is that the drainage module includes two water collection pipes, the inlets of the two water collection pipes are fixedly connected to the drainage holes in the seedling tray, the pipes in the two water collection pipes are inclined to the horizontal plane and have an outlet at the lowest point, the outlets of the two water collection pipes are fixedly connected to a drainage pipe, and the inner side of the two flow guide support frames has a main water inlet and is fixedly connected to the other end of the drainage pipe.

[0010] A further improvement of this utility model is that: both of the two flow guide support frames have a main drain outlet on their outer sides and are threaded with a plug; the two flow guide support frames have a secondary drain outlet on the upper side of the main inlet; the secondary drain outlet of the flow guide support frame is fixedly connected to a drain hose; the flow guide folding frame has a water channel inside; the flow guide folding frame has an inlet on its side and is fixedly connected to the other end of the drain hose; and the flow guide folding frame has a drain outlet at its bottom.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a corn planting and seedling raising device. When multiple layers need to be placed, the sliding lock is pushed in the opposite direction to unlock the slide groove, and the limiting seat is slid out of the storage rack. The folding frame and the flow guiding folding frame are rotated downward and unfolded to a horizontal support state. The unfolded folding frame and the flow guiding folding frame can be inserted into the connecting seat of the lower layer device to provide stable support for the upper layer seedling trays and realize the vertical stacking of multiple layers of seedling trays.

[0015] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1 As shown, this utility model provides a corn seedling cultivation device, including a seedling tray 1. A support module 2 is fixedly connected to the outside of the holes in the seedling tray 1. A drainage outlet is opened at the bottom of the holes in the seedling tray 1 and a filter screen is installed above the drainage outlet. A drainage module 3 is fixedly connected below the drainage hole in the seedling tray 1. The holes opened on the surface of the seedling tray 1 are used to place corn seedling substrate and seeds. At the same time, the drainage outlet is pre-set at the bottom of the holes, and the filter screen installed above the drainage outlet can prevent the substrate from being lost with water and drain excess water from the holes, thus avoiding water accumulation and root rot in the corn seedlings.

[0016] like Figure 2As shown, this utility model provides a technical solution: the support module 2 includes two flow guide support frames 21 and two support frames 24. A flow guide folding frame 22 is rotatably connected to the bottom of each of the two flow guide support frames 21, and a folding frame 25 is rotatably connected to the bottom of each of the two support frames 24. A limiting seat 23 is fixedly connected to the outer side of each flow guide folding frame 22 and folding frame 25. The flow guide support frame 21 and the flow guide folding frame 22 are rotatably connected and can rotate around the connection point. When idle, the flow guide folding frame 22 can be rotated upwards and retracted into the storage frame 210 to save storage space. When multiple layers need to be connected, the flow guide folding frame 22 can be rotated downwards and unfolded to provide support points for the lower layer devices. The support frame 24 and the folding frame 25 are also rotatably connected and are symmetrically distributed on both sides of the seedling tray 1 along with the flow guide support frame 21 and the flow guide folding frame 22. When unfolded, the folding frame 25 and the flow guide folding frame 22 together form a support structure, ensuring uniform force distribution when multiple layers are stacked and preventing the seedling tray 1 from tilting or deforming.

[0017] like Figure 3 As shown, this utility model provides a technical solution: Connecting seats 26 are fixedly connected to the top of both the flow guide support frame 21 and the support frame 24. All four connecting seats 26 are fixedly connected to the seedling tray 1. A sealing ring 27 is fixedly connected inside each connecting seat 26. Each connecting seat 26 connected to the flow guide support frame 21 has a float 29 inside, and a limiting seat 28 is fixedly connected above the float 29. When the upper layer of accumulated water flows into the connecting seat 26 through the flow guide folding frame 22, the water level gradually rises. The buoyancy overcomes the weight of the float 29, causing the float 29 to float upwards, exposing the drain outlet at the bottom of the limiting seat 28, allowing the accumulated water to flow smoothly into the lower layer. When water accumulates in the lower layer device and attempts to flow back upward through the connecting seat 26, the reverse water flow impacts the bottom of the float 29, giving the float 29 an upward pressure. This causes the float 29 to fit tightly against the drain outlet of the limiting seat 28, forming a physical seal and completely blocking the backflow path. At the same time, one end of the connecting seat 26 is fixedly connected to the seedling tray 1, and the other end is used to insert the flow guide 22 of the lower layer device. It is a key connecting component for multi-layer drainage. The sealing ring 27 fixed inside the connecting seat 26 can fit tightly against the insertion end of the flow guide 22, eliminating connection gaps and preventing water from leaking from the connection.

[0018] like Figure 4 As shown, this utility model provides a technical solution: the seedling tray 1 has a storage rack 210 fixedly connected to the inner side of the two folding frames 25 and the two flow guiding folding frames 22. The outer side of the two storage racks 210 is provided with a sliding groove and is slidably connected to the outer limit seat 23. The storage rack 210 is slidably connected to a sliding lock 211 on the outer side of the sliding groove.

[0019] like Figure 5As shown, this utility model provides a technical solution: the drainage module 3 includes two water collection pipes 31, the inlets of the two water collection pipes 31 are fixedly connected to the drainage holes in the seedling tray 1, the pipes in the two water collection pipes 31 are inclined to the horizontal plane and have water outlets at the lowest point, the water outlets of the two water collection pipes 31 are fixedly connected to drainage pipes 32, the inner sides of the two flow guide support frames 21 are opened with main water inlets and fixedly connected to the other end of the drainage pipes 32, when the sliding lock 211 blocks the slide groove, the sliding path of the limiting seat 23 is restricted, so that the limiting seat 23 cannot slide out of the storage frame 210, thereby maintaining the storage state of the folding frame 25 and the flow guide folding frame 22, which is convenient for the device to be transported or for the use of a single seedling device.

[0020] like Figure 6 As shown, this utility model provides a technical solution: Two main drain outlets are opened on the outer sides of the two flow guide support frames 21 and are threadedly connected to plugs 34. Secondary drain outlets are opened above the main inlets on both flow guide support frames 21. Drainage hoses 33 are fixedly connected to the secondary drain outlets of the flow guide support frames 21. A water channel is opened inside the flow guide folding frame 22. A water inlet is opened on the side of the flow guide folding frame 22 and is fixedly connected to the other end of the drainage hose 33. A drain outlet is opened at the bottom of the flow guide folding frame 22. The water inlet of the water collection pipe 31 is connected to the drain hole at the bottom of the seedling tray 1. The corresponding and fixed connection can simultaneously receive excess water discharged from multiple holes, preventing water from accumulating at the bottom of the seedling tray 1 and reducing uneven substrate moisture. At the same time, gravity can be used to allow the water in the water collection pipe 31 to flow naturally to the lowest outlet, reducing water residue and preventing the water in the pipe from deteriorating and smelling bad. The outlet of the water collection pipe 31 is connected to the drain pipe 32, so that the collected water is transported through the drain pipe 32 to the guide support frame 21 at the other end. The water is then guided into the internal passage of the guide support frame 21 through the main inlet of the guide support frame 21.

[0021] The working principle of this corn planting and seedling raising device will be explained in detail below.

[0022] like Figure 1-6As shown, when multiple seedling devices need to be connected, first slide the sliding lock 211 to connect the slide groove of the storage rack 210, releasing the restriction on the range of motion of the limiting seat 23. Then, slide the limiting seat 23 out of the slide groove of the storage rack 210. The limiting seat 23 drives the folding frame 25 and the flow guiding folding frame 22 to rotate and unfold. Then, insert the unfolded folding frame 25 and the flow guiding folding frame 22 into the connecting seat 26 of the new seedling device. At this time, the flow guiding support frame 21 of the new seedling device is connected to the flow guiding folding frame 22 of the original seedling device through the connecting seat 26, forming a new passage. At the same time, when the flow guiding folding frame 22 unfolds, the drainage hose 33 will move along with it, maintaining the connection with the connecting seat 26 and guiding the flow. The top of the support frame 21 is also equipped with a water inlet and connected to the connecting seat 26. When multiple seedling devices are connected, the water accumulated in the seedling devices will be collected through the water collection pipe 31. The water inlet of the water collection pipe 31 is fixedly connected to the drainage hole in the seedling tray 1. Due to its inclined pipe and the outlet located at the lowest point, the water gradually flows to the outlet under the action of gravity, and then flows from the outlet into the drain pipe 32. At the same time, the other end of the drain pipe 32 is fixedly connected to the main water inlet of the guide support frame 21, so that the water flows from the drain pipe 32 into the guide support frame 21. When the plug 34 on the guide support frame 21 is not opened, the water level in the guide support frame 21 will rise continuously as the water continues to flow in. Until the water level reaches the secondary drain outlet of the flow guide support frame 21, the accumulated water flows from the secondary drain outlet to the drain hose 33. The other end of the drain hose 33 is fixedly connected to the water inlet on the side of the flow guide folding frame 22, allowing the accumulated water to flow into the flow guide folding frame 22. The flow guide folding frame 22 has a drain outlet at the bottom. The accumulated water in the flow guide folding frame 22 will flow from the bottom drain outlet into the connecting seat 26 of the seedling device below. At the same time, the sealing ring 27 set between the connecting seat 26 and the flow guide folding frame 22 can prevent water leakage. When the water flows into the connecting seat 26, it first enters the limiting seat 28 and then flows from the drain outlet at the bottom of the limiting seat 28 to the float 29. As the water level rises, the float 29 is floated up, thus exposing the area below the connecting seat 26. At this point, water flows from the drain outlet of the guide folding frame 22 into the guide support frame 21, and then circulates continuously until the accumulated water reaches the guide support frame 21 where the plug 34 is removed. The accumulated water then flows out from the main drain outlet of the guide support frame 21. When the lower layer of accumulated water attempts to flow back upward through the drain outlet, the water flow will impact the bottom of the float ball 29, giving the float ball an upward force. This causes the float ball 29 to be squeezed by the reverse water flow to the drain outlet at the bottom of the limiting seat 28. At the same time, because the diameter of the float ball 29 is larger than the diameter of the drain outlet of the limiting seat 28, the float ball 29 will fit against the drain outlet of the limiting seat 28, forming a physical seal, blocking the reverse water flow, and ensuring that the substrate and holes of the upper seedling tray are not contaminated by the lower layer of accumulated water.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
