Description

Technical Field

[0001] This utility model relates to the field of seedling tray technology, specifically an easy-to-demold seedling tray for crop seedling cultivation. Background Technology

[0002] A seedling tray is a container with multiple regularly arranged holes (or "seedling cups") specifically designed for centralized sowing and seedling cultivation. It provides each seed with an independent, standardized, and optimized initial growth environment, thereby achieving high germination rates, uniform seedling cultivation, and facilitating subsequent transplanting.

[0003] In the process of crop seedling cultivation, seedlings in seedling trays need to be transplanted when they grow to a certain size. To remove the seedlings from the seedling tray, it is necessary to grasp the rootstock of the seedling and lift it upwards to demold. During this process, it is very easy to damage the seedlings due to excessive force, which will affect the survival rate later. Moreover, when demolding in batches, it is necessary to exert a lot of effort to control the grip to avoid damaging the seedlings, which is not only tiring but also affects work efficiency. Based on this, an easy-to-demold seedling tray for crop seedling cultivation is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-demold seedling tray for crop seedling cultivation in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-demold seedling tray for crop seedling raising, comprising a seedling tray assembly, wherein the seedling tray assembly consists of a top plate, a seedling trough, a conical soft rubber sleeve, a bottom conical cavity, a bottom plate, and permeable holes; Multiple seedling troughs are provided, and the multiple seedling troughs are arranged in a matrix on the top of the top plate. The conical soft rubber sleeve is fixed to the bottom of the top plate and is aligned with and connected to the seedling trough. The bottom conical hole is fixed to the bottom of the conical soft rubber sleeve. The seedling trough, the conical soft rubber sleeve, and the bottom conical hole form a pit for placing nutrient soil. The base plate is fixed to the bottom of multiple bottom cone-shaped holes, and the water-permeable holes are opened at the bottom of the base plate and communicate with the bottom cone-shaped holes; Pressing the top plate downwards close to the bottom plate allows the seedling trough to fold outwards and shrink, thus enabling the nutrient soil to be demolded from the seedling trough. A support assembly is also provided between the bottom plate and the top plate. The support assembly is used to provide support and reinforcement when the top plate and the bottom plate are far apart.

[0006] As a further embodiment of this utility model: the support assembly includes a fixing sleeve, a concave support frame, and a C-shaped card holder; The fixing sleeve is symmetrically fixed to the top of the base plate, and the C-shaped card holder is symmetrically fixed to the top of the top plate; The two longitudinal sections at the bottom of the concave support frame are rotatably connected to the inner sides of the two fixed sleeves. When the concave support frame is rotated to the vertical position, the top longitudinal section of the concave support frame is engaged with the inner side of the C-shaped bracket to provide support for the top plate and bottom plate in the opposite direction.

[0007] As a further improvement of this utility model: the bottom of the opening of the C-shaped card holder is formed with a protrusion, and a straight groove is opened in the middle of the bottom of the opening of the C-shaped card holder.

[0008] As a further embodiment of this utility model: the top longitudinal center of the concave support frame is formed with an arc-shaped concave portion, and the concave support frame and the arc-shaped concave portion are integrally formed by plastic injection molding.

[0009] As a further embodiment of this utility model: the top plate, seedling trough, conical soft rubber sleeve, bottom conical hole, bottom plate, water-permeable hole, fixing sleeve, C-shaped card seat, protrusion and straight groove are integrally formed by composite injection molding process.

[0010] As a further embodiment of this utility model: two sets of the support components are symmetrically arranged at both ends of the top plate and the bottom plate, and one or more sets of support components can be selectively arranged on both sides of the top plate and the seedling trough.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting up a seedling tray assembly with a conical soft rubber sleeve, the top plate moves down close to the bottom plate, causing the conical soft rubber sleeve to fold outward and shrink into an "N" shape. This allows the nutrient soil inside the conical soft rubber sleeve to detach from the sleeve and be exposed to the top of the top plate. In this way, the exposed nutrient soil can be grasped and lifted to transplant the seedlings. This effectively avoids damage to the seedlings caused by direct contact, and no precise control of force is required during the transfer process, making the overall operation easier and more efficient.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 In this embodiment of the utility model, an easy-to-demold seedling tray for crop seedling raising includes a seedling tray assembly 1, which is composed of a top plate 101, a seedling trough 102, a conical soft rubber sleeve 103, a bottom conical hole 104, a bottom plate 105, and a water permeable hole 106. Multiple seedling troughs 102 are provided, and the multiple seedling troughs 102 are arranged in a matrix on the top of the top plate 101. The conical soft rubber sleeve 103 is fixed to the bottom of the top plate 101 and is aligned and connected with the seedling troughs 102. The bottom conical hole 104 is fixed to the bottom of the conical soft rubber sleeve 103. The seedling troughs 102, the conical soft rubber sleeve 103, and the bottom conical hole 104 form a trough for placing nutrient soil. The base plate 105 is fixed to the bottom of multiple bottom cone cavities 104, and the water permeable hole 106 is opened at the bottom of the base plate 105 and communicates with the bottom cone cavities 104; The top plate 101 is pressed down near the bottom plate 105 to make the seedling trough 102 turn outward and shrink, thereby realizing the demolding operation of the nutrient soil from the seedling trough 102. A support assembly 2 is also provided between the bottom plate 105 and the top plate 101. The support assembly 2 is used to provide support and reinforcement for the top plate 101 and the bottom plate 105 when they are far apart. Support component 2 includes a fixing sleeve 201, a concave support frame 202, and a C-shaped bracket 204; The fixing sleeve 201 is symmetrically fixed to the top of the base plate 105, and the C-shaped bracket 204 is symmetrically fixed to the top of the top plate 101; The two longitudinal portions at the bottom of the concave support frame 202 are rotatably connected to the inner sides of the two fixed sleeves 201. When the concave support frame 202 is rotated to the vertical position, the longitudinal portion at the top of the concave support frame 202 is engaged with the inner side of the C-shaped card seat 204 to provide support for the top plate 101 and the bottom plate 105 in the away position.

[0016] In this embodiment: When using this seedling tray for seedling cultivation, the method of use is the same as that of existing seedling trays on the market: First, fill the "conical seedling hole groove" composed of seedling trough 102, conical soft rubber sleeve 103, and bottom conical hole 104 with nutrient soil. Then, use a scraper to level it and press holes on the top of the nutrient soil according to the position of the conical seedling hole groove. Then, put the seeds into each hole one by one, and then cover the seeds with another layer of nutrient soil. Then, place the seedling tray 1 in a suitable environment and perform operations such as temperature control, moisture control, light adjustment, regular ventilation, and disease and pest prevention. In addition, the permeable hole 106 is set to prevent excessive water accumulation in the nutrient soil when watering the seedlings, so as to keep the nutrient soil at a suitable moisture level. During the above operation, the concave support frame 202 is in an upright position and is engaged with the inner side of the C-shaped bracket 204 (e.g., Figure 1 / 2), thereby keeping the top plate 101 and bottom plate 105 in a stable, distant state, that is, keeping the conical soft rubber sleeve 103 in a stable unfolded state. When seedlings need to be transplanted, the procedure is as follows: First, manually open the concave support frame 202 outward (it should be noted that the opening of the C-shaped card seat 204 faces outward). This releases the support limit between the top plate 101 and the bottom plate 105. Then, apply a uniform downward pressing force to the top plate 101, causing the top plate 101 to move down closer to the bottom plate 105. During this process, the conical soft rubber sleeve 103 folds outward and shrinks into an "N"-shaped state. In this way, the nutrient soil inside the conical soft rubber sleeve 103 is demolded from the conical soft rubber sleeve 103 and exposed to the top of the top plate 101. After that, the exposed part of the nutrient soil can be grasped and lifted to transplant the seedlings. This can effectively avoid damage to the seedlings caused by direct contact. Moreover, there is no need to precisely control the force during the transfer process, making the overall operation easier and more efficient. After the seedlings are transplanted, the top plate 101 can be reset so that the conical soft rubber sleeve 103 is returned to its initial state. Then, the concave support frame 202 can be rotated and inserted into the inner side of the C-shaped card seat 203 for easy secondary use.

[0017] Please refer to this carefully. Figure 2 , Figure 4 The bottom of the opening of the C-type card holder 204 is formed with a protrusion 205, and a straight groove 206 is provided in the middle of the bottom of the opening of the C-type card holder 204. The concave support frame 202 has an arc-shaped concave portion 203 formed in the longitudinal center of its top. The concave support frame 202 and the arc-shaped concave portion 203 are integrally formed by plastic injection molding.

[0018] In this embodiment: through the structural arrangement of the protrusion 205, when the concave support frame 202 is inserted into the inner side of the C-shaped card seat 203, the protrusion 205 can provide outward displacement limit for the concave support frame 202, thereby ensuring the stability of the concave support frame 202 in the engagement state; The straight slot 206 provides good elastic restoring force at the bottom of the opening of the C-type card holder 203, making it easy for the concave support frame 202 to be squeezed in or detached. The structure of the arc-shaped concave portion 203 creates a gap between the arc-shaped concave portion 203 and the top plate 101, which facilitates the insertion of a hand into this gap to pull and open the concave support frame 202.

[0019] Please refer to this carefully. Figures 1-3 The top plate 101, seedling trough 102, conical soft rubber sleeve 103, bottom conical hole 104, bottom plate 105, water permeable hole 106, fixing sleeve 201, C-shaped card seat 204, protrusion 205, and straight groove 206 are integrally formed by composite injection molding process.

[0020] In this embodiment, it should be noted that the top plate 101, bottom cone cavity 104, bottom plate 105, fixing sleeve 201, and C-type card seat 204 can be made of polypropylene (PP) material, which is the same as the material of existing seedling trays. The cone-shaped soft rubber sleeve 103 is made of thermoplastic elastomer (TPE / TPR) material, which has good elasticity and flexibility, good recovery after repeated extrusion, is non-toxic and odorless, meets the requirements of plant planting, and has a mature injection molding process, which is easy to combine with hard plastics. The seedling tray component 1 is integrally molded using a composite injection molding process, which facilitates standardized and large-scale processing, keeps costs under control, and makes it easy to promote and use.

[0021] Please refer to this carefully. Figures 1-3 Two sets of support components 2 are symmetrically arranged at both ends of the top plate 101 and the bottom plate 105. One or more sets of support components 2 can be selectively arranged on both sides of the top plate 101 and the seedling trough 102.

[0022] In this embodiment, the support components 2 are symmetrically arranged at both ends to facilitate balanced force distribution and provide sufficient support. If greater support is required, the support components 2 can be arranged on both sides of the top plate 101 and the seedling trough 102, so as to meet more seedling requirements.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
