Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an adjustable corn seedling tray. Background Technology

[0002] Corn seedling trays are an indispensable tool in the corn seedling stage. They are usually made of plastic and have a disc-shaped structure with many regularly arranged seedling cups on them.

[0003] In terms of assembly, most traditional corn seedling trays lack effective connection structures, resulting in poor stability after assembly. This not only reduces the overall efficiency of seedling cultivation but also may cause seedlings to separate during handling and movement due to weak assembly and the fact that seedling trays are mostly injection molded and have a thin overall structure, making them prone to deformation. This can damage the seedlings. During seedling growth, the roots exhibit hydrotropism and nutrient tropism. Existing seedling trays usually have drainage holes at the bottom of the tray bowls for drainage. However, seedling roots can easily penetrate these drainage holes. When seedlings need to be removed from the tray bowls for transplanting (demolding), the entanglement of the roots with the drainage holes makes demolding extremely difficult. Forced demolding will severely damage the seedling roots, reduce the seedling survival rate, and affect the subsequent growth and yield of corn. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable corn seedling tray. By setting multiple sets of connecting columns, rubber pads and positioning holes in the tray, the assembly process of the tray and seedling tray is greatly simplified. The deformable cone cover and filter cloth set in the cup effectively prevent the seedling roots from passing through the leakage holes. The deformable cone cover that can be pulled down can easily separate the seedlings from the cup during demolding, significantly improving demolding efficiency and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable corn seedling tray includes a tray and a seedling tray. Multiple positioning columns are fixedly installed at the bottom of the tray, and multiple tray bowls are fixedly installed at the bottom of the tray. The inner cavity of the tray bowls is connected to the inner cavity of the tray. A deformable cone cover is fixedly connected inside the tray bowls, and a filter cloth is movably connected to the deformable cone cover.

[0007] As a further preferred embodiment of this utility model, a connecting column is fixedly installed on the upper end of the positioning column, and a rubber pad is fixedly installed on the upper end of the connecting column. The tray can collect excess water generated during irrigation, and the cooperation of the positioning column, the connecting column, and the rubber pad can position and install the tray, thereby ensuring that when multiple sets of trays and seedling trays are laid for seedling cultivation, there is sufficient operating space between two adjacent sets of trays and seedling trays, which facilitates the placement and removal of trays and seedling trays.

[0008] As a further preferred embodiment of this utility model, two positioning holes are provided on both sides of the seedling tray, and the positioning holes are inserted and installed on the corresponding connecting columns.

[0009] As a further preferred embodiment of this utility model, the cup has a funnel-shaped structure that is narrow at the bottom and wide at the top.

[0010] As a further preferred embodiment of this utility model, the lower end of the cup is provided with multiple water flow channels. When the lower end of the cup contacts the tray, excess irrigation water can be discharged into the tray through the water flow channels.

[0011] As a further preferred embodiment of this utility model, the deformable cone cover is provided with multiple leakage holes, and the deformable cone cover is provided with deformation grooves along its outline on the outside. The leakage holes facilitate the leakage of excess irrigation water into the tray, while the deformation grooves facilitate the deformation of the deformable cone cover. A tie rod is fixedly installed at the top inside the deformable cone cover.

[0012] As a further preferred embodiment of this utility model, the filter cloth is divided into a polyester fiber base cloth layer, a transition layer, and a polypropylene non-woven filter layer. The base cloth layer and the transition layer provide the necessary strength and stability for the support skeleton of the entire filter cloth, ensuring that the filter cloth will not deform or break during use. The finer polyester fiber yarns are sparsely woven to connect the base cloth layer and the filter layer, while initially intercepting larger particles of the culture soil, reducing the burden on the filter layer. The polypropylene non-woven fabric is tightly attached to the transition layer, responsible for accurately intercepting fine particles in the culture soil.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the multiple sets of connecting columns, rubber pads, and positioning holes inside the tray facilitate the assembly of the tray and the seedling tray. The deformable cone cover and filter cloth inside the tray bowl prevent the seedling roots from passing through the leakage holes and affecting the demolding. At the same time, the deformable cone cover that can be pulled down can improve the efficiency of demolding the seedlings from the tray bowl. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, the present invention provides an adjustable corn seedling tray, including a tray 1 and a seedling tray 3. Multiple positioning posts 2 are fixedly installed at the bottom of the tray 1, and multiple cups 4 are fixedly installed at the bottom of the tray 1. The inner cavity of the cups 4 is connected to the inner cavity of the tray 1. A deformable cone cover 5 is fixedly connected inside the cups 4, and a filter cloth 13 is movably connected to the deformable cone cover 5.

[0023] like Figures 1-4 As shown, a connecting column 6 is fixedly installed on the upper end of the positioning column 2, and a rubber pad 7 is fixedly installed on the upper end of the connecting column 6. The tray 1 is designed to collect excess water generated during irrigation. The positioning column 2, the connecting column 6, and the rubber pad 7 work together to position the tray 1, thereby ensuring that when multiple sets of trays 1 and seedling trays 3 are laid out for seedling cultivation, there is sufficient operating space between two adjacent sets of trays 1 and seedling trays 3, which facilitates the placement and removal of trays 1 and seedling trays 3. Two positioning holes 8 are opened on both sides of the seedling tray 3, and the positioning holes 8 are inserted into the corresponding connecting column 6.

[0024] like Figure 5As shown, the support bowl 4 has a funnel-shaped structure that is narrower at the bottom and wider at the top. Multiple water channels 9 are provided at the lower end of the support bowl 4. When the lower end of the support bowl 4 contacts the tray 1, excess irrigation water can be drained into the tray 1 through the water channels 9. Multiple leakage holes 10 are provided inside the deformable cone shroud 5. Deformation grooves 11 are provided along the outline of the deformable cone shroud 5. The leakage holes 10 facilitate the leakage of excess irrigation water into the tray 1, while the deformation grooves 11 facilitate the deformation of the deformable cone shroud 5. A tie rod 12 is fixedly installed at the top inside the deformable cone shroud 5. The filter cloth 13 consists of a polyester fiber base cloth layer, a transition layer, and a polypropylene non-woven filter layer. The base cloth layer and the transition layer provide the necessary strength and stability for the support skeleton of the entire filter cloth 13, ensuring that the filter cloth 13 will not deform or break during use. The finer polyester fiber yarns are sparsely woven to connect the base cloth layer and the filter layer, while also initially intercepting larger particles of the culture soil, reducing the burden on the filter layer. The polypropylene non-woven fabric is tightly attached to the transition layer, responsible for accurately intercepting fine particles in the culture soil.

[0025] It should be noted that this utility model is an adjustable corn seedling tray. During assembly, the positioning post 2 fixed at the bottom of the tray 1 fits tightly with the positioning holes 8 on both sides of the seedling tray 3. The connecting post 6 at the upper end of the positioning post 2 is inserted into the positioning hole 8. The rubber pad 7 on the connecting post 6 provides buffering and stabilizing effect when the two are connected, thus enabling the tray 1 and the seedling tray 3 to be assembled quickly and accurately. Furthermore, when multiple sets of trays 1 and seedling trays 3 are used for seedling cultivation, this design ensures that a suitable distance is maintained between adjacent sets, facilitating the placement and removal of trays 1 and seedling trays 3, and effectively improving the efficiency of seedling cultivation. In addition, the tray bowl 4 has a funnel-shaped structure that is narrow at the bottom and wide at the top, with a water channel 9 at the bottom to allow excess water to flow through during irrigation. Water first flows into the bowl 4 and then through the water channel 9 into the tray 1, thus completing the drainage process. At the same time, the filter cloth 13 inside the bowl 4 prevents the seedling roots from passing through the seepage hole 10. The seepage hole 10 inside the deformable cone 5 is used to drain excess water. The filter cloth 13 is composed of a polyester fiber base layer, a transition layer, and a polypropylene non-woven filter layer, which can effectively intercept the potting soil particles, prevent them from clogging the seepage hole 10, and prevent the seedling roots from passing through. When it is necessary to demold the seedlings, by pulling the pull strip 12 at the top inside the deformable cone 5, the deformable cone 5 deforms from the deformation groove 11, easily separating the seedlings from the bowl 4, significantly improving the efficiency of demolding the seedlings from the bowl 4 and reducing damage to the seedling roots.
