According to the novel seedling raising tray, the seedling raising trays on the upper layer and the lower layer can be stacked in a staggered mode and form interlocking, so that the seedling raising trays on the upper layer are prevented from sliding down to the seedling raising trays on the lower layer, and the novel seedling raising tray can still be manufactured through traditional compression molding and plastic uptake.

Description

Technical Field

[0001] The utility model relates to the field of pot seedling raising trays. Background Art

[0002] Seedling trays made of pressed plastic film are widely used for growing seedlings of crops such as vegetables and grains. These trays typically consist of a rectangular plastic film sheet, formed into a series of recessed bowls arranged in a specific order. The bowls have water holes at the bottom. Crop seeds are placed in the bowls, and soil and water are added to cultivate the seedlings for transplanting. To improve seedling emergence, seedling trays are often placed in a specific temperature and humidity environment (seedling chamber) after sowing to promote germination and seedling success. To increase space utilization in the seedling chamber, seedling trays are typically stacked and placed inside the chamber. Common seedling trays currently on the market have recessed bowls on the front and corresponding raised bowls on the back. When stacked and placed in the chamber, the raised bowls on the top tray press against the recessed bowls on the bottom tray, hindering germination and seedling emergence. If the seedlings are stacked in a staggered manner, the connection area between the bowls on the upper surface of the tray is small and cannot be positioned, so the seedlings often slide into the bowls, making the stacked tray seedling cultivation effect poor. In order to better promote the application of stacked tray seedling cultivation, the seedling tray must be improved to solve the problem of overlapping bowls. Utility Model Content

[0003] The purpose of this utility model is to provide a new seedling raising tray in pots, so as to solve the problem that the pots and bowls overlap when the seedling raising trays are stacked and the growth of seedlings is affected. To this end, the utility model adopts the following technical solutions:

[0004] A seedling raising tray that can be staggered and stacked comprises a tray body, on which are arranged a plurality of bowls that are recessed in the tray body, and a central water-permeable hole is provided at the bottom of the bowls. The tray body is characterized in that protrusions are provided between the bowls, and the protrusions and the central water-permeable hole are configured to be able to be inserted and matched, so that when the seedling raising trays are staggered and stacked, the central water-permeable hole of the upper seedling raising tray is inserted and locked by the protrusion of the lower seedling raising tray.

[0005] On the basis of adopting the above technical solutions, the present invention can also adopt the following further technical solutions or use them in combination:

[0006] The protrusions are hollow protrusions, and when the seedling raising trays are stacked and stored, the protrusions of the lower seedling raising trays can be inserted into the hollows on the back sides of the protrusions of the upper seedling raising trays.

[0007] The protrusion is in the shape of a truncated cone.

[0008] The tray body is rectangular, and the plurality of bowls are arranged vertically and horizontally on the tray body. The spacing between adjacent bowls in the vertical direction is equal, and the spacing between adjacent bowls in the horizontal direction is equal.

[0009] The protrusions are located in rows on the plate body between the mouths of adjacent bowls.

[0010] The center distance between adjacent protrusions in the same row of protrusions is consistent with the center distance between the central water-permeable holes in the same row.

[0011] The protrusions in the same row and the central water holes of the corresponding bowls in the same row are on the same straight line.

[0012] The seedling raising tray is an integrated structure formed by vacuum molding or compression molding of a plastic hard film sheet.

[0013] Due to the technical solution of the present invention, the upper and lower seedling trays can be stacked in an offset manner and interlocked, thereby preventing the upper seedling tray from sliding onto the lower seedling tray. Moreover, the new seedling tray of the present invention can still be manufactured using traditional compression molding and vacuum molding. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] With reference to the accompanying drawings, the utility model provides a seedling raising tray for seedlings in pots that can be staggered and stacked, comprising a tray body 1, on which a plurality of bowls 2 that are recessed in the tray body are arranged, a central water hole 20 being provided at the bottom of the bowls, and a protrusion 4 being provided on the tray body 1 between the bowls 2, the protrusion 4 and the central water hole 20 being configured to be insertable and compatible, for example, the contour shapes are similar, but the water hole is slightly larger than the plane size of the protrusion 4, so that when the seedling raising trays are staggered and stacked, the central water hole 20 of the upper seedling raising tray 100 is inserted and locked by the protrusion 4 of the lower seedling raising tray 200; or the contour shapes are not similar, but it is also possible that when the seedling raising trays are staggered and stacked, the central water hole 20 of the upper seedling raising tray 100 is inserted and locked by the protrusion 4 of the lower seedling raising tray 200.

[0019] The protrusion 4 is a hollow protrusion, so that when the seedling trays are stacked, the protrusion of the lower seedling tray 200 can be inserted into the hollow 40 on the back of the protrusion of the upper seedling tray 100. Preferably, the shape of the protrusion is a truncated cone, which can have an insertion guide effect.

[0020] The seedling tray is an integrated structure formed from a plastic hard film sheet through vacuum molding or compression molding. The hollow protrusions and bowls 2 are both formed during the vacuum molding or compression molding process. The bowls 2 are of uniform size, equidistantly spaced vertically and horizontally, and are shaped like an inverted truncated cone, a square truncated cone, or other polygonal truncated cone, with a larger top and smaller bottom. The central water holes at the bottom of each bowl are uniform in size. The protrusions 4 are arranged in rows on the tray body between the mouths of adjacent bowls. The protrusions 4 can be circular, square, polygonal, or any other shape. Their outer contours should be equal to or smaller than the size of the central water holes at the bottom of the bowls. The center-to-center distance between adjacent protrusions 4 in the same row is consistent with the center-to-center distance between the central water holes 20 in the same row. The protrusions 4 in the same row and the central water holes 20 of the corresponding bowls in the same row are aligned on the same straight line.

[0021] like Figure 1 As shown, in the present invention, the protrusion 4 can be arranged between each two adjacent rows of bowls 2, such as Figure 4 As shown, the protrusion 4 can be set between the bowls 2 of two adjacent columns in every other column, or the protrusion 4 can be set between the bowls 2 of two adjacent columns in more columns. Figure 1 、 Figure 4 In the embodiment shown, the protrusions 4 may also be arranged in alternate rows or multiple rows.

[0022] With the seedling raising tray of the above structure, after sowing, the trays are staggered and stacked together with the bottom of the bowl of the upper seedling raising tray being located on the tray body between two adjacent bowls of the lower seedling raising tray. The central water-permeable hole 20 of the bowl of the upper seedling raising tray 100 is put on the protrusion of the lower seedling raising tray 200 to stably position it, so that the seedling raising trays can be staggered when stacked together for raising seedlings and germinating seedlings, so that the upper seedling raising tray has no effect on the germination of the lower seedling raising tray.

[0023] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the field of the present invention are included in the protection scope of the present invention.
