Description

Technical Field

[0001] This utility model belongs to the technical field of seedling equipment, and in particular relates to a constant temperature and humidity device for germinating larch seeds. Background Technology

[0002] Larch plays a crucial role in forestry ecological protection, timber supply, and carbon sequestration. Effective seed germination is the foundation for large-scale artificial seedling cultivation, directly determining the quantity and quality of seedlings. Due to its dormancy characteristics, larch seeds have an extremely low natural germination rate and require stringent germination environments. The suitable germination temperature needs to be stable at 15-25℃, the relative humidity needs to be maintained at 80%-90%, and air circulation and light conditions also need to be ensured. Any deviation in environmental factors may lead to a decrease in germination rate, a prolongation of germination time, or even seed death.

[0003] Currently, the simple greenhouse germination method used for larch seed germination can regulate temperature through coal-fired or electric heating equipment, but humidity control mainly relies on manual watering at regular intervals. This is not only labor-intensive and costly, but also difficult to achieve even coverage, which can easily cause local water accumulation or dryness, leading to seed mold or dehydration. At the same time, the closed greenhouse environment lacks effective ventilation, and poor air circulation can easily breed harmful bacteria, affecting seed viability.

[0004] To address these issues, we have provided a temperature and humidity control device for germinating larch seeds. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature and humidity device for germinating larch seeds. By combining the storage mechanism, the humidity control component and the ventilation component, it solves the problem that the humidity control of the simple greenhouse germination method used in the prior art for germinating larch seeds mainly relies on manual timed watering, which makes it difficult to achieve uniform coverage and lacks effective ventilation, thus affecting the seed activity.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This invention relates to a constant temperature and humidity device for germinating larch seeds. It includes an insulated shell, a storage mechanism fixedly connected to the inner cavity of the insulated shell, a humidity-regulating component fixedly connected to one side of the insulated shell, and a ventilation component connected to the top of the insulated shell. The storage mechanism includes an inner shell disposed within the inner cavity of the insulated shell. Connecting plates are fixedly connected to the top and bottom of the inner shell. Brackets are fixedly connected to both sides of the connecting plates, and trays are provided on the top of the brackets. Connecting blocks are fixedly connected to both sides of the inner shell, with one side of each connecting block fixedly connected to the insulated shell. Heaters are fixedly connected to both sides of the top of the inner cavity of the insulated shell, and a light is fixedly connected to the top of the inner cavity of the insulated shell. The insulated shell effectively blocks interference from external ambient temperature, reducing internal heat loss or external heat intrusion. The trays on the top of the brackets have good air permeability and drainage, preventing water accumulation during seed germination. The decomposition process, while promoting air circulation, creates a suitable microenvironment for seed germination. The heater can be activated when the ambient temperature is low, heating the internal space of the insulation shell with its radiant heat to ensure that the larch seeds are within a suitable temperature range. At the same time, the lighting simulates natural light conditions, providing the necessary light for seed germination. Different stages of seed germination have different light requirements. By controlling the switching on and off of the lighting and the duration of light exposure, the light requirements of larch seeds during the germination process can be met, promoting seed germination and growth. The combination of the insulation shell and the storage mechanism forms a relatively closed and stable internal space, effectively reducing the interference of external environmental factors on seed germination. The seed storage structure, consisting of trays, racks, and connecting plates, ensures that the seeds have enough space to be placed while also facilitating air circulation among the seeds, preventing uneven local temperature and humidity caused by seed accumulation, and improving the success rate and germination quality of seed germination.

[0008] The present invention is further configured such that the humidification component includes a pump body, one side of which is fixedly connected to the heat insulation shell, the bottom of which is connected to a water inlet pipe, and the top of which is connected to a spray pipe. One side of the spray pipe penetrates one side of the heat insulation shell and extends into the inner cavity of the inner shell, and the bottom of the spray pipe is connected to an atomizing nozzle. The pump body is connected to an external water source through the water inlet pipe to pressurize and deliver water to the spray pipe, which is then sprayed out by the atomizing nozzle at the bottom. Compared with traditional water spraying methods, this invention can quickly adjust the internal humidity, ensuring that the humidity is uniform and stable within the suitable range for larch seed germination, preventing seeds from becoming moldy or dying due to water accumulation, providing an ideal humidity environment for seed germination, and significantly improving the germination success rate.

[0009] The present invention is further configured such that the ventilation component includes a fixed plate, the bottom of the fixed plate is fixedly connected to the insulation shell, the top of the fixed plate is connected to a ventilation hood, the bottom of the inner cavity of the ventilation hood is fixedly connected to a fan, and the top of the ventilation hood is fixedly connected to a grille. When the fan is running, it draws air from inside the insulation shell, accelerates air circulation, and prevents harmful bacteria from growing due to prolonged stagnation of internal air. The top grille can block external debris from entering, while ensuring smooth air discharge and maintaining the cleanliness and hygiene of the inside of the device.

[0010] The present invention is further configured such that support columns are fixedly connected to the four corners of the top of the heat insulation shell, and a top plate is fixedly connected to the top of the support columns. The support columns are connected to the top plate, which enhances the overall structural strength and stability of the device and prevents the device from being hit by objects above or eroded by rainwater.

[0011] The present invention is further configured such that a guide groove is provided at the bottom of the inner cavity of the inner shell, and a drain pipe is connected to the bottom of one side of the heat preservation shell. The drain pipe is connected to the guide groove. When the humidifying component sprays too much water or produces condensation, the accumulated water can be quickly collected through the guide groove and discharged through the drain pipe.

[0012] The present invention is further configured such that a cover plate is hinged to one side of the heat insulation shell, and a handle is fixedly connected to one side of the cover plate. The cover plate hinged to one side of the heat insulation shell, together with the handle design, makes it easy for staff to open and close the device.

[0013] The present invention is further configured such that a fixed base is fixedly connected to one side of the pump body, and one side of the fixed base is fixedly connected to the heat insulation shell. The fixed base and the heat insulation shell are fixedly connected to provide stable support for the pump body, effectively reducing vibration and displacement during pump operation and ensuring stable operation of the pump body.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model forms a double-layered heat-insulating space by combining the inner shell and the heat-insulating shell, which effectively reduces heat loss and ensures stable internal temperature. The design of the connecting plate, bracket and tray inside the inner shell makes it convenient to place seeds in layers, which not only improves space utilization, but also ensures that each layer of seeds has a good air circulation environment. The heater quickly raises the internal temperature, and the lighting simulates natural light conditions to provide suitable light for seed germination, which helps to improve the germination rate and germination quality.

[0016] 2. This utility model uses a pump to draw water from the inlet pipe, and then sprays the water evenly into the inner shell through the spray pipe and atomizing nozzle. This can quickly regulate the internal humidity and ensure that the humidity is stable within the range suitable for larch seed germination. Compared with manual watering, atomized water spraying is more uniform, avoids excessively high or low humidity in some areas, reduces the risk of seed mold or dryness, and improves the seed survival rate.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6This utility model is a constant temperature and humidity device for germinating larch seeds, including a heat-insulating shell 1, a storage mechanism 2 fixedly connected to the inner cavity of the heat-insulating shell 1, a humidity-regulating component 3 fixedly connected to one side of the heat-insulating shell 1, and a ventilation component 4 connected to the top of the heat-insulating shell 1. The storage mechanism 2 includes an inner shell 21, which is disposed in the inner cavity of the heat-insulating shell 1. A connecting plate 22 is fixedly connected to the top and bottom of the inner shell 21. A bracket 23 is fixedly connected to both sides of the surface of the connecting plate 22. A tray 24 is provided on the top of the bracket 23. A connecting block 25 is fixedly connected to both sides of the inner shell 21. One side of the connecting block 25 is fixedly connected to the heat-insulating shell 1. A heater 26 is fixedly connected to both sides of the top of the inner cavity of the heat-insulating shell 1. A lighting lamp 27 is fixedly connected to the top of the inner cavity of the heat-insulating shell 1.

[0028] Specifically: the insulation shell 1 effectively blocks interference from external ambient temperature, reducing internal heat loss or external heat intrusion. The tray 24 on top of the bracket 23 has good air permeability and drainage, preventing seeds from rotting due to water accumulation during germination, while also facilitating air circulation and creating a suitable microenvironment for seed germination. The heater 26 can be activated when the ambient temperature is low, heating the internal space of the insulation shell 1 with its emitted heat to ensure that the larch seeds are within a suitable temperature range. Simultaneously, the lighting 27 simulates natural light conditions, providing the necessary light for seed germination at different stages. Different seeds have different light requirements for germination. By controlling the on / off state of the lighting lamp 27 and the duration of light exposure, the light requirements of larch seeds during the germination process can be met, promoting seed germination and growth. The cooperation between the heat preservation shell 1 and the storage mechanism 2 forms a relatively closed and stable internal space, effectively reducing the interference of external environmental factors on seed germination. The seed storage structure composed of the tray 24, the bracket 23 and the connecting plate 22 not only ensures that the seeds have enough space to be placed, but also facilitates air circulation between the seeds, preventing uneven local temperature and humidity caused by seed accumulation, and improving the success rate and germination quality of seed germination.

[0029] Example 2

[0030] Please see Figure 1-6Based on Embodiment 1, the humidification component 3 includes a pump body 31, one side of which is fixedly connected to the insulation shell 1. A water inlet pipe 32 is connected to the bottom of the pump body 31, and a spray pipe 33 is connected to the top of the pump body 31. One side of the spray pipe 33 penetrates one side of the insulation shell 1 and extends into the inner cavity of the inner shell 21. An atomizing nozzle 34 is connected to the bottom of the spray pipe 33. The ventilation component 4 includes a fixing plate 41, the bottom of which is fixedly connected to the insulation shell 1. A ventilation hood 42 is connected to the top of the fixing plate 41, and the bottom of the inner cavity of the ventilation hood 42... A fan 43 is fixedly connected to the top of the ventilation hood 42, a grille 44 is fixedly connected to the top of the insulation shell 1, support columns 5 are fixedly connected to the four corners of the top of the insulation shell 1, a top plate 6 is fixedly connected to the top of the support columns 5, a guide groove 7 is opened at the bottom of the inner cavity of the inner shell 21, a drain pipe 8 is connected to the bottom of one side of the insulation shell 1, the drain pipe 8 is connected to the guide groove 7, a cover plate 9 is hinged to one side of the insulation shell 1, a handle is fixedly connected to one side of the cover plate 9, a fixed seat 10 is fixedly connected to one side of the pump body 31, and one side of the fixed seat 10 is fixedly connected to the insulation shell 1.

[0031] Specifically: Pump body 31 is connected to an external water source through water inlet pipe 32, pressurizing and delivering water to spray pipe 33, which is then sprayed out from atomizing nozzle 34 at the bottom. Compared with traditional water spraying methods, this can quickly regulate internal humidity, ensuring uniform and stable humidity within the suitable range for larch seed germination, preventing seeds from becoming moldy or dying due to water accumulation, providing an ideal humidity environment for seed germination, and significantly improving the germination success rate. When fan 43 is running, it draws air from inside the insulation shell 1, accelerating air circulation and preventing harmful bacteria from growing due to prolonged stagnation of internal air. Top grille 44 can block external debris from entering while ensuring smooth airflow. The device is designed to facilitate drainage and maintain cleanliness inside. The support column 5 is connected to the top plate 6, which enhances the overall structural strength and stability of the device and prevents it from being damaged by objects above or rainwater. When the humidifying component 3 sprays too much water or produces condensation, the accumulated water can be quickly collected through the guide channel 7 and discharged through the drain pipe 8. The cover plate 9 on one side of the insulation shell 1 is hinged and designed with a handle, making it easy for staff to open and close the device. The fixed seat 10 is fixedly connected to the insulation shell 1, providing a stable support for the pump body 31. During the operation of the pump body 31, vibration and displacement are effectively reduced, ensuring the stable operation of the pump body 31.

[0032] The working principle of this utility model is as follows: the staff places the larch seed cultivation pot on the tray 24, and places the tray 24 on top of the bracket 23, closes the cover 9, so that the heat preservation shell 1 and the storage mechanism 2 cooperate to form a relatively closed space, effectively blocking the interference of external environmental temperature, reducing the loss of internal heat or the intrusion of external heat, and providing a stable basic environment for seed germination.

[0033] Once the device is operational, if the ambient temperature is low, the heater 26 will be activated. The evenly distributed design of the heater 26 ensures that the heat emitted by it can diffuse evenly within the insulation shell 1, heating the internal air and ensuring that the larch seeds are always within the suitable temperature range of 15-25℃. Simultaneously, the lighting 27 can simulate natural light conditions by controlling its switch and illumination duration according to the needs of different seed germination stages, providing the necessary light factors for seed germination and promoting seed germination and growth.

[0034] The pump body 31 is connected to an external water source through the water inlet pipe 32. When the device detects that the internal humidity is lower than the suitable range (80%-90%) required for larch seed germination, the pump body 31 is activated, pressurizing and delivering water to the spray pipe 33. The atomizing nozzle 34 refines the water into tiny particles and sprays them evenly. Compared with the traditional water spraying method, it can quickly and evenly adjust the internal humidity, keeping the humidity stable within a suitable range and preventing the seeds from becoming moldy or dying due to water accumulation.

[0035] When the fan 43 is running, it draws air from the insulation shell 1 to accelerate air circulation and prevent harmful bacteria from growing due to prolonged air stagnation. During the entire germination process, if the moisturizing component 3 sprays too much water or produces condensation, the guide channel 7 will quickly collect the accumulated water and discharge it outside the insulation shell 1 through the drain pipe 8 connected to the guide channel 7.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described.
