Description

Technical Field

[0001] This utility model relates to a paper flower seedling tray with a tearable rim around the seedling cup. Background Technology

[0002] Against the backdrop of rapid scientific and technological development, agricultural production is also following the trend of the times by undergoing automation and mechanization. Seedling trays are an important planting device in automated and mechanized agriculture, and they are widely used in factory-style plant seedling cultivation and planting processes.

[0003] In actual production, common seedling trays are injection molded in one piece, consisting of multiple seedling cups connected together. In factory-style seedling cultivation, this type of tray allows for efficient use of space during seed germination, achieving intensive breeding. For example, Chinese Patent Publication No. CN222108683U discloses a novel tobacco seedling tray, including a paper seedling tray and a base plate used in conjunction with it. Tear lines are provided at the connections between the seedling cells, allowing the individual seedling cells to be separated by tearing along these lines. However, existing seedling trays use ordinary straight-line die-cut structures for tearing, requiring two hands and making it difficult to control the force, easily leading to deviations in the tear path or damage to the edges of the seedling cells, affecting planting efficiency and the integrity of the seedling cells. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing a paper flower seedling tray with a tearable rim around the seedling cup.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a paper flower seedling tray with tearable edges around the seedling cups, comprising a paper seedling tray body, wherein the seedling tray body is provided with multiple seedling cups, and wavy tearable lines are distributed around the connection points above each seedling cup.

[0006] Furthermore, the wavy tearable line is made by pre-pressing wavy die-cutting and creasing.

[0007] Furthermore, the bottom of the seedling cup has a mesh-like fragile layer.

[0008] Furthermore, the seedling tray body is made of paper material containing slow-release fertilizer and insect repellent.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed, with wavy tearable lines distributed around the connection point above each seedling cup. The stress concentration point is formed by the wave crest, and the forced tearing path extends along the wave crest, realizing one-handed operation and controllable tearing direction.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] Example 1: As Figures 1-4 As shown, this utility model discloses a paper flower seedling tray with tearable edges around the seedling cups. It includes a paper tray body 1, which has multiple seedling cups 2 arranged in a matrix. Wavy tearable lines 3 are distributed around the upper connecting points of each seedling cup 2. After tearing along these wavy tearable lines, the individual seedling holes can be separated, resulting in multiple independent seedling cups. The wavy peaks create stress concentration points, forcing the tearing path to extend along the peaks, enabling one-handed operation. Furthermore, the tearing path strictly follows a preset direction, preventing damage to the edges of the seedling holes or tearing deviation that could reduce planting efficiency. This directly solves the problems of inconvenient tearing operation and uncontrollable tearing paths in existing technologies.

[0014] In this embodiment, the wavy tearable line 3 is made by pre-pressed wavy die-cutting and indentation. The continuous wavy indentation allows for controllable indentation depth, and the wavy geometry guides stress concentration through periodic undulations, ensuring that tearing always occurs along the line connecting the wave crests. Compared to the straight tear lines of existing technologies, the mechanical guiding characteristics of the wavy indentation reduce sensitivity to operational force, allowing separation to be completed with a single hand, and also reducing path deviation. In this embodiment, the wavy geometric parameters are: the wavy tearable line is a periodic wavy continuous indentation.

[0015] The processing technology for the wavy tearable line is as follows: a customized wave-shaped die-cutting machine is used to simultaneously complete the forming and creasing of the seedling trays.

[0016] When using it, the wavy tear-out line makes it easy to tear off the appropriate seedling cup and put it directly into the flower pot as needed.

[0017] Example 2: Figures 2-4 As shown, the only difference between this embodiment and Embodiment 1 is that the bottom of the seedling cup 2 is a mesh-like fragile layer 4. During transplanting, the mesh-like fragile layer breaks easily with light pressure, allowing the roots to detach along with the substrate, thus avoiding root damage during seedling removal. Furthermore, designing the bottom of the seedling cup as a mesh-like fragile layer allows plant roots to grow faster and break through the tray material, while also preventing root rot.

[0018] Existing paper seedling trays have a common permeable bottom structure. During transplanting, seedlings must be manually pulled out or forcibly removed from the tray, which easily leads to roots sticking to the tray, causing root breakage or damage, and prolonging the recovery period. In this embodiment, the mesh-like fragile layer forms a vulnerable surface through high-density indentation. This high-density indentation divides the bottom paper layer into tiny, fragile units, which can withstand the swelling force of moisture during the seedling stage. During transplanting, only slight pressure is needed to cause directional cracking. Light pressure during transplanting causes the bottom to crack evenly, allowing the roots to detach as a whole with the substrate, avoiding direct mechanical damage to the roots from pulling the seedlings. This facilitates the plant's roots breaking through the tray and quickly taking root in the new pot. In short, this design reduces root damage and shortens the recovery period.

[0019] In this embodiment, the mesh-like fragile layer adopts an integrated molding process: the seedling cup is formed and the mesh is indented simultaneously through a hot press mold, which is different from the traditional secondary processing process.

[0020] The wavy tear line and the fragile mesh layer at the bottom of the seedling cup simplify the seedling-transplanting process and reduce manual intervention.

[0021] Example 3: The difference between this example and Example 1 lies in the material used to manufacture the seedling tray. Specifically, the seedling tray is made of paper material containing slow-release fertilizer and insect repellent. Specifically, the slow-release fertilizer and insect repellent are uniformly dispersed in a pulp suspension and integrally formed using a long-wire paper machine. Premixing the slow-release fertilizer and insect repellent into the paper material ensures continuous nutrient supply and simultaneous pest and disease control during the seedling stage, reducing the frequency of manual fertilization and pesticide spraying. This design reduces the incidence of tobacco seedling diseases, improves pest control efficiency, and increases fertilizer utilization.

[0022] In this embodiment, the slow-release fertilizer and insect repellent are made of coated granules. Both the slow-release fertilizer granules and the insect repellent are coated with a biodegradable polymer coating, gradually releasing nutrients as the paper degrades, with a release period covering 30-60 days of seedling growth. Specifically, the insect repellents are Bacillus subtilis, thiamethoxam, and carbendazim. This design reduces the incidence of tobacco seedling diseases, improves pest control efficiency, and increases fertilizer utilization.

[0023] Functional paper materials release nutrients and pesticides simultaneously during degradation, forming a "simplified seedling system" that significantly reduces overall planting costs (e.g., reducing fertilization frequency by 3-4 times per cycle).

[0024] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).

[0025] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0026] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
