Description

Technical Field

[0001] This utility model relates to the field of agricultural tools technology, and in particular to a seedling raising device that is easy to promote. Background Technology

[0002] Seedling cultivation means nurturing seedlings. Originally, it referred to cultivating seedlings in nurseries, hotbeds, or greenhouses in preparation for transplanting into the ground. It can also refer to the stage when various small organisms, after being artificially protected, can survive independently. As the saying goes, "Strong seedlings are half the harvest." Seedling cultivation is a labor-intensive, time-consuming, and technically demanding task.

[0003] Seedling trays are widely used in various agricultural sectors, including fruits, vegetables, and landscaping seedlings. Conventional seedling trays are simply plastic containers with multiple compartments, lacking temperature control capabilities. This means temperature control relies on adjusting the external environment, such as greenhouse temperatures. However, different plants require different temperatures, necessitating separate seedlings in different greenhouses or areas within greenhouses in colder regions, which is time-consuming and labor-intensive. Furthermore, temperature significantly affects the seedling cultivation of some plants, making traditional seedling trays unsuitable for promoting seedling technology. Therefore, designing a simple, convenient, and temperature-controlled seedling device is crucial for the widespread adoption of seedling technology. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a seedling raising device that is easy to promote. The addition of a top cover structure makes the entire seedling raising device form a relatively sealed structure, which is beneficial for temperature control. Furthermore, a temperature-controlled opening and closing component is provided on the top of the top cover to control the size of the through hole, making it convenient to adjust the temperature and maintain temperature stability.

[0005] The technical solution of this utility model is a seedling raising device that is easy to promote, including a top cover, a seedling cup group, a side plate and a tray;

[0006] The side panels are installed on the tray and, when combined with it, form a support for supporting the seedling cups; at the same time, the support forms a limiting structure for the top cover, which is used to limit and fix the top cover during installation.

[0007] The seedling cup set is used to support the soil and plants; when the seedling cup set is installed with the support, both the upper and lower parts are suspended; the top cover is transparent and has a temperature-controlled opening and closing device at the top to maintain a relatively stable temperature inside the device.

[0008] Preferably, several through holes are reserved on the top cover; the opening and closing device is located at the center of the top cover and at the through hole; the opening and closing device increases the opening area of ​​the through hole as the temperature rises, and decreases the opening area of ​​the through hole as the temperature falls.

[0009] Preferably, the opening and closing components include a base in the middle, an openable cover, a support, and a movable component;

[0010] The base has a hollow center to form a cavity that can accommodate expandable materials; a cover plate is placed on the base to seal the cavity; multiple sets of support members are provided to connect with the top cover and form a support structure for the entire opening and closing mechanism; the cavity of the base is provided with several elastic conduits, which are connected to the movable parts.

[0011] The moving part slides along the upper surface of the through hole;

[0012] As the temperature rises, the expansion material stored in the cavity expands, the internal pressure gradually increases, and the conduit gradually changes from a contracted state to an expanded state, pushing the moving part out and moving it away from the base, thus increasing the opening area of ​​the through hole.

[0013] Preferably, the upper surface of the through hole is an inclined surface, with the side closer to the base being lower and the side farther from the base being higher;

[0014] As the temperature gradually decreases, the expansion material contracts, and the conduit gradually enters a contracted state; under the action of gravity, the moving part moves closer to the base relative to the inclined sliding support, causing the opening area of ​​the through hole to gradually decrease.

[0015] Preferably, the cover plate and the base are connected by a threaded connection.

[0016] Preferably, the seedling cup set is designed with a flat-topped pyramidal structure that is larger at the top and smaller at the bottom; the seedling cup set is a biodegradable pulp seedling cup.

[0017] Preferably, snap-fit ​​elements are provided along both sides of the tray; the snap-fit ​​elements are protruding elastic thin plate structures; and they are provided with inclined surfaces for guidance facing outwards from the tray.

[0018] Preferably, the side panel slides along the inclined surface on the snap-fit ​​when assembled with the pallet, so that the snap-fit ​​abuts against the side panel; there is an interference fit between the side panel and the pallet.

[0019] Preferably, the top cover has slots on both the left and right sides; when the top cover is installed with the tray, the slots and the snap-fit ​​parts engage; and the edge of the top cover is snapped into the stepped structure formed between the side panel and the tray.

[0020] Preferably, several air holes are symmetrically arranged along both sides of the tray; the air holes are used for air flow and nutrient solution overflow; when the seedling cup group is assembled in the support, the bottom of the cup group is lower than the horizontal height of the air holes and in contact with the liquid surface.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] 1. This utility model provides a simple seedling raising device, which is formed by the combination of a top cover, a seedling cup assembly, a side plate, and a tray to form an overall structure; the top cover is made of transparent material and does not affect photosynthesis; at the same time, the opening and closing parts set on the top cover can control the opening area of ​​the through hole, which is conducive to maintaining temperature balance and promoting plant growth; by adding different expansion materials to the base, different temperatures can be set for different plants, and the opening area of ​​the through hole can be adjusted within the specified temperature range.

[0023] 2. The seedling cup set has a flat-topped pyramidal structure, wider at the top and narrower at the bottom; the seedling cups are made of biodegradable pulp. After seedling cultivation, there is no need to remove the plants from the seedling cup set; simply separate the cups and plant directly. The easily biodegradable material will not damage the soil. Furthermore, the flat-topped pyramidal structure reduces the amount of soil needed for hilling and increases the space between different plants, facilitating root respiration.

[0024] 3. The side panels form an auxiliary support device between the tray and the top cover. Together with snap-fit ​​connectors, they securely attach the top cover to the tray, facilitating plant transport. Additionally, the air holes on the side panels not only allow for air circulation and plant respiration but also function as overflow holes, ensuring the water level in the tray remains at a suitable height. This reduces the frequency of watering and is more beneficial for seedling cultivation. Using this device for seedling cultivation effectively reduces watering frequency and eliminates the need to regulate external temperature. Different temperature ranges can be set for different plants, allowing cultivation to proceed outside of greenhouses or polytunnels. This invention has a simple structure and multiple functions, significantly reducing manual labor intensity and promoting the widespread adoption of plant seedling cultivation technology.

[0032] Example 1

[0033] like Figure 1 As shown, the present invention proposes a seedling raising device that is easy to promote, including a top cover 1, a seedling cup group 2, a side plate 3, and a tray 4;

[0034] Side plate 3 is installed on tray 4, and together they form a support to support the seedling cup group 2. At the same time, the support forms a limiting structure for the top cover 1, which is used to limit and fix the top cover 1 during installation. The seedling cup group 2 is used to support the soil and plants. When the seedling cup group 2 is installed with the support, its upper and lower parts are suspended. The top cover 1 is transparent, which facilitates sunlight exposure and does not affect the photosynthesis of plants. Furthermore, an opening and closing device 5 that can be opened and closed according to temperature is provided on the top of the top cover 1 to maintain a relatively stable temperature inside the device.

[0035] like Figure 5 As shown, the top cover 1 has several through holes 11; the opening and closing element 5 is located at the center of the top cover 1 and at the through hole 11; the opening and closing element 5 increases the opening area of ​​the through hole 11 as the temperature rises, and decreases the opening area of ​​the through hole 11 as the temperature falls. In this embodiment, the opening and closing element 5 includes a base 52 in the middle, an openable cover plate 51, a support member 53, and a movable member 54; the base 52 is hollow in the middle to form a cavity that can accommodate expandable materials; the cover plate 51 is set on the base 52 to seal the cavity; the support member 53 is provided with multiple sets for connection with the top cover 1 to form a support structure for the entire opening and closing element 5; the cavity of the base 52 is provided with several elastic conduits 55, which are connected to the movable member 54; the movable member 54 slides along the upper surface of the through hole 11; the through hole 11 can be configured as a spindle-shaped hole structure, while the corresponding movable member 54 is an arc-shaped structure; the initial state is as follows. Figure 5 As shown, the movable part 54 covers most of the through hole 11, leaving only gaps on both sides to facilitate gas exchange.

[0036] As the temperature rises, the expandable material stored in the cavity expands, the internal pressure gradually increases, and the guide tube 55 gradually changes from a contracted state to an expanded state, pushing the movable part 54 outwards and moving it away from the base 52, increasing the opening area of ​​the through hole 11, and finally forming... Figure 6As shown in the diagram; in this embodiment, a expandable material is added to the base 52, specifically a material with a large gas volume expansion coefficient or a solid-liquid phase change material can be selected; when a gas is used, since the gas itself is greatly affected by temperature, its volume will increase when the temperature rises and decrease when the temperature falls; common examples include nitrogen and helium; during use, nitrogen / helium is pre-injected into the base 52 to maintain a certain internal pressure, and the air intake is adjusted to form a state as shown in the diagram at the temperature most suitable for the growth of the plant. Figure 5 As shown in the diagram; when the temperature rises, the opening area of ​​the through hole 11 increases to facilitate heat dissipation; while when the temperature decreases, the opening area of ​​the through hole 11 gradually decreases to help with heat preservation.

[0037] When solid-liquid phase change materials are selected, their phase change temperature is adjusted to the optimal temperature for the growth of the plant by changing the composition or ratio of the solid-liquid phase change materials. When the temperature rises, the solid-liquid phase change materials absorb the heat and gradually liquefy, and the volume of the liquefied phase change materials increases. This drives the moving part 54 to move, thereby increasing the opening area of ​​the through hole 11. At the same time, the phase change materials absorb the heat and store heat. When the nighttime temperature is low, the heat absorbed by the phase change materials is gradually released, which helps to maintain temperature stability. As the temperature further decreases, the liquid phase material gradually turns into a solid and flows from the conduit 55 into the base 52 under the action of gravity.

[0038] In this embodiment, the upper surface of the through hole 11 is an inclined surface, with the side closer to the base 52 being lower and the side farther from the base 52 being higher. As the temperature gradually decreases, the telescopic material contracts, and the guide tube 55 gradually turns into a contracted state. Under the action of gravity, the movable part 54 slides relative to the side of the inclined surface closer to the base 52, causing the opening area of ​​the through hole 11 to gradually decrease. The guide tube 55 can be made of a material with a large amount of axial expansion and contraction but a small amount of radial expansion and contraction. When the telescopic material expands and contracts, it can better push the movable part 54 to move through the guide tube 55.

[0039] Example 2

[0040] The present invention proposes a seedling raising device that is easy to promote. Unlike embodiment 1, in this embodiment, the cover plate 51 and the base 52 are connected by a threaded connection, forming a relatively sealed structure after connection, which prevents the expansion material stored in the base 52 from overflowing. At the same time, the threaded connection also makes it easier to open and close the cover plate 51 and the base 52, and facilitates the addition of different amounts of expansion material according to different types of plants, making it suitable for seedling raising of different plants.

[0041] Example 3

[0042] This utility model proposes a seedling raising device that is easy to promote, which differs from Embodiment 1 in that, as Figure 1The seedling cup group 2 shown is designed with a flat-topped pyramidal structure, wider at the top and narrower at the bottom. Seedling cup group 2 is made of biodegradable pulp. After seedling cultivation is complete, there is no need to remove the plants from seedling cup group 2; simply separate the seedling cup group 2 and plant directly. The easily biodegradable material will not damage the soil. Furthermore, the flat-topped pyramidal structure helps reduce the amount of soil used for hilling and increases the space between different plants, facilitating root respiration.

[0043] In this embodiment, as Figure 3 As shown, several air holes 42 are symmetrically arranged along both sides of the tray 4; the air holes 42 are used for air flow and overflow; when the seedling cup group 2 is assembled in the support, the bottom of the cup group is lower than the horizontal height of the air holes 42 and is in contact with the liquid surface.

[0044] A certain amount of water or nutrient solution can be added to the tray 4 to meet the needs of plant growth. The air holes 42 not only facilitate gas flow for plant respiration but also serve as overflow holes, ensuring that the water level in the tray 4 is at a suitable height. At this height, the bottom of the cup assembly can directly contact the liquid surface, allowing the cup assembly to absorb the nutrient solution into the soil, thus reducing the frequency of watering and making it more conducive to plant seedling cultivation.

[0045] Example 4

[0046] This utility model proposes a seedling raising device that is easy to promote, which differs from Embodiment 1 in that, as Figure 4 As shown, snap-fit ​​members 41 are provided on both sides of the tray 4; the snap-fit ​​member 41 is a raised elastic thin plate structure; and it is provided with a sloping surface 411 for guidance in the direction of the outer side of the tray 4.

[0047] like Figure 3 As shown, when the side panel 3 is assembled with the tray 4, it can slide along the inclined surface 411 on the snap-fit ​​member 41, so that the snap-fit ​​member 41 abuts against the side panel 3; there is an interference fit between the side panel 3 and the tray 4; a firm connection structure is formed between the side panel 3 and the tray. When a cover plate needs to be installed later, as... Figure 1 As shown, slots 12 are provided on both the left and right sides of the top cover 1; when the top cover 1 is installed with the tray 4, the slots 12 and the snap-fit ​​parts 41 are engaged; and the edge of the top cover 1 is inserted into the stepped structure formed between the side plate 3 and the tray 4; the top cover 1 is engaged with the tray 4 and the side plate 3, so when the device needs to be taken out, it can be lifted directly through the top cover 1 without having to lift the entire device from the bottom, which facilitates the transfer of seedlings.

[0048] In summary, this utility model provides a simple seedling raising device, which is formed by the combination of a top cover 1, a seedling cup assembly 2, a side plate 3, and a tray 4. The plant and soil are pre-placed in the seedling cup assembly 2 and then placed into the device. The transparent top cover 1 does not affect photosynthesis. The opening and closing device 5 on the top cover 1 controls the opening area of ​​the through hole 11, which helps maintain temperature balance and promotes plant growth. The seedling cup assembly 2 is made of biodegradable pulp. After seedling raising is completed, there is no need to remove the plant from the seedling cup assembly 2, and it will not damage the soil. The side plate 3 forms an auxiliary support device between the tray 4 and the top cover 1, and with the snap-fit ​​device 41, the top cover 1 and the tray 4 can be firmly installed together, facilitating plant transportation. The air vent 42, in addition to facilitating gas flow for plant respiration, also serves as an overflow vent, ensuring the water level in the tray 4 is at a suitable height. This helps reduce the frequency of watering and is more conducive to plant seedling raising. When using this device for seedling cultivation, the frequency of watering is effectively reduced, and there is no need to rely on adjusting the external ambient temperature to control the temperature. Different temperature ranges can be set for different plants, so that the cultivation work can be carried out without greenhouses or polytunnels. This utility model has a simple structure and multiple functions, which greatly reduces the intensity of manual labor and is also conducive to the promotion of plant seedling cultivation technology.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
