Description

Sheet structure and seedling raising cup formed by folding same

Technical Field

The utility model relates to a seedling raising device, in particular to a sheet structure and a seedling raising cup formed by folding the sheet structure.

Background

The seedling raising cup is a plastic product for raising seedlings, and has become an important tool in the industrial seedling production process because the seedling raising cup can save the seed consumption and ensure the consistent growth of plant seedlings. However, the seedling raising cup with the existing structure is usually formed by integral injection molding, and the shape of the seedling raising cup is round or square, so that the seedling raising cup is large in volume and occupies a large space, and is not beneficial to boxing, storage or transportation.

The patent of the utility model with the bulletin number of CN 216362775U discloses a single-hole turnover seedling tray, which comprises a first body, a second body, a cover plate, a convex block, a water flowing groove and a folding groove, wherein the tray is flattened in a general state, and can be folded to form a cylinder body when in use. Therefore, the seedling raising cup can be stacked and stored in a stacking manner under the flattened state, occupies small space, has high space utilization rate after being packaged, and solves the problems that the seedling raising cup with the conventional structure is large in size and difficult to store or transport. However, the seedling tray of this structure has the following drawbacks:

one is that the hydrophobic air permeability is not good. The seedling tray is only hydrophobic and breathable through the root guiding opening at the bottom, has small holes and single positions, is not beneficial to respiration and normal growth of seedling root systems, and is especially not suitable for cultivating the exogenous mycorrhizal edible fungus forest seedlings belonging to aerobic bacteria;

and secondly, the cylinder body may be scattered during use. The seedling tray is an independently used seedling raising device, does not have a structure matched with other devices for use, only locks and fixes the second body and the cover plate through the clamping strips and the clamping grooves, and the buckled connecting structure is easy to separate the second body from the cover plate due to growth of seedling roots or other factors when the tray is used for raising seedlings for a long time, so that the barrel is scattered, and damage is caused to the seedling body or the seedling roots.

As shown in fig. 1 and fig. 2, ventilation folding holes 4 are arranged in each inner folding groove 3 at intervals along the length direction of the inner folding groove, and the ventilation folding holes 4 are matched with the inner folding grooves 3 to enable the rectangular substrate 1 or the connecting sheet 2 to be folded more easily, and enable the side wall of the folded seedling cup to have ventilation property, so that the root system of the seedling can breathe more easily and grow normally.

In this embodiment, a side of the rectangular substrate 1 for constituting the inner wall of the seedling cup is defined as a first surface, and a side of the rectangular substrate 1 for constituting the outer wall of the seedling cup is defined as a second surface. As shown in fig. 1, the bottom of the first surface of each rectangular substrate 1 is provided with a bottom sealing block 5 in a protruding manner, the bottom sealing block 5 has a rectangular pyramid shape with an open bottom, and the open bottom surface of the bottom sealing block 5 coincides with the first surface of the rectangular substrate 1. After the embodiment is folded and formed into the seedling raising cup, the bottom sealing blocks 5 at the bottoms of the four rectangular substrates 1 are spliced to form the bottom structure of the seedling raising cup, so that the substrate in the cavity is supported.

Further, each rectangular substrate 1 is provided with a root guide groove 6 recessed from the first surface toward the second surface in the longitudinal direction. In this embodiment, three root guide grooves 6 are provided on each rectangular substrate 1.

The top of the second surface of each rectangular substrate 1 is provided with a clamping block 7 in a protruding mode, the clamping block 7 is in a cuboid shape with an open bottom, and the open surface of the clamping block 7 is overlapped with the second surface of the rectangular substrate 1. The seedling raising cup after the folding molding of the embodiment is matched with the plug support 11 with the existing structure, so that the width of the rectangular substrate 1 is equal to or smaller than the width of the through hole on the plug support 11, the thickness of the two clamping blocks 7 added to the width of the rectangular substrate 1 is larger than the width of the through hole on the plug support 11, and the seedling raising cup can be clamped in the through hole of the plug support 11 by means of the clamping blocks 7.

The connecting piece 2 can be overlapped and press-fit with the leftmost rectangular substrate 1, so that the folded four rectangular substrates 1 maintain a cylindrical structure. In this embodiment, one surface of the connecting piece 2, which is used to form the outer sidewall of the seedling raising cup, is defined as a second surface, and the other surface is defined as a first surface. The connecting piece 2 may be of exactly the same shape as the rectangular substrate 1: the bottom of the first surface is provided with a bottom sealing block 5 in a protruding mode, the top of the second surface is provided with a clamping block 7 in a protruding mode, and a root guiding groove 6 recessed from the first surface to the second surface is formed in a part between the bottom sealing block 5 and the clamping block 7 along the length direction; the connecting piece 2 can also be a structure which omits the bottom sealing block 5 and only arranges the clamping block 7 and the root guiding groove 6 on the basis of the shape of the rectangular substrate 1, as shown in the figure 1 of the embodiment.
