Description

Technical Field

[0001] This utility model relates to the technical field of magnetic mineral separation equipment in mineral processing engineering, and in particular to a seedling raising device for improving the germination rate of Japanese cedar seeds. Background Technology

[0002] The branches of the Japanese cedar (Cunninghamia lanceolata) are tough yet slightly flexible and elastic, giving it superior resistance to wind, snow pressure, and icing compared to Chinese fir. Japanese cedar prefers neutral to slightly sunny conditions, tolerates shade when young, and thrives in warm, humid climates, requiring an average annual temperature of 14–19°C and annual rainfall exceeding 1000 mm. It is particularly well-suited to maritime or mountainous climates with high humidity, frequent fog, and relatively cool summers. Before seedling cultivation, Japanese cedar seeds need to be disinfected by soaking them in a 0.5% potassium permanganate solution or a 1% bleaching powder solution for 30 minutes. To ensure the quantity and quality of Japanese cedar seedlings, seeds need to be sampled for cultivation testing to determine their germination rate. Current technology involves burying Japanese cedar seeds in the soil of a cultivation rack before cultivation. However, due to the strict requirements of Japanese cedar regarding air temperature, humidity, and air stability within the cultivation area, the germination and survival rates of Japanese cedar seeds are relatively low. Therefore, a seedling cultivation device to improve the germination rate of Japanese cedar seeds is proposed. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-3 This utility model provides a seedling raising device for improving the germination rate of Japanese cedar seeds, comprising:

[0029] Germination box, with a detachable light-blocking top cover 1 at the top;

[0030] The insulation mechanism includes four sets of insulated water tanks 2, which are respectively installed on the four side walls outside the germination box. The insulated water tanks 2 are detachably connected to the germination box. An insulation pad 3 is detachably connected to the outer wall of the insulated water tank 2. The insulation pad 3 is made of opaque material.

[0031] The seedling bed includes a water storage tank 4 fixed at the bottom of the seedling box, a perforated plate 5 fixedly connected to the top of the water storage tank 4, and a sponge 6 laid on the top surface of the perforated plate 5.

[0032] The humidification mechanism is located on the bottom surface of the shading top cover 1. The humidification mechanism and the insulated water tank 2 are fixedly connected by a connecting pipe 7, and a water pump 8 is installed on the connecting pipe 7.

[0033] Temperature and humidity monitoring device, which is installed inside the germination box and electrically connected to a host computer;

[0034] A visual monitoring component is installed inside the germination box, and the visual inspection mechanism is electrically connected to the host computer.

[0035] Among them, water pump 8 is electrically connected to the host computer.

[0036] When using this invention, firstly, the soaked Japanese cedar seeds are evenly spread on top of the sponge 6, then covered with a moistened gauze, and the entire cover is sealed. The temperature inside the germination box is kept constant by the setting of the heat preservation water tank 2. When the humidity inside the germination box decreases, the water in the heat preservation water tank 2 is directly pumped into the humidification mechanism by the water pump 8 for atomization and humidification, ensuring that the temperature and humidity inside the germination box meet the requirements for germination. Finally, the germinated seeds are hardened off and transplanted.

[0037] This utility model connects the heat preservation mechanism and the humidification mechanism, uses constant temperature water heating, and the humidification mechanism directly extracts water from the heat preservation water tank 2 for atomization, thus avoiding the influence of water mist on the temperature inside the germination box.

[0038] The design is further optimized. The germination box includes a base plate 9, with four sets of support columns 10 vertically fixedly connected to the top of the base plate 9. The four sets of support columns 10 are symmetrically arranged in pairs. The light-shielding top cover 1 is detachably connected to the top surface of the four sets of support columns 10. A transparent enclosure 11 is fixedly connected between adjacent support columns 10. The transparent enclosure 11 has ventilation holes. The four sets of heat-insulating water tanks 2 are arranged one-to-one with the four sets of transparent enclosure 11. The heat-insulating water tanks 2 and the support columns 10, as well as the heat-insulating water tanks 2 and the heat-insulating pads 3, are detachably connected by several connecting components.

[0039] The top cover and the support column 10 are fixed with screws to enable the placement and removal of the seedling bed. After the seeds germinate, the heat preservation water tank 2 on the outer wall of the transparent enclosure 11 is removed. The inner wall of the seedling box exchanges air with the outside through the ventilation holes, so that the seedling box can be used for transplanting seedlings after the seeds germinate.

[0040] The scheme is further optimized. The connecting components include a positioning sleeve 12 and a bolt 13. A slot 14 is provided on the support column 10. The insulated water tank 2 is snapped into the slot 14. A through groove 15 is provided on the side wall of the slot 14. The through groove 15 has a rectangular cross-sectional shape. A first support plate 16 is slidably connected in the through groove 15. The positioning sleeve 12 is coaxially fixedly connected to the first support plate 16. A second support plate 17 is fixedly connected in the through groove 15. A compression spring 18 is fixedly connected between the second support plate 17 and the first support plate 16. The bolt 13 passes through the insulation pad 3, the first support plate 16, the second support plate 17 and is threadedly connected to the positioning sleeve 12. The compression spring 18 is sleeved on the outer wall of the bolt 13. The first support plate 16 is threadedly connected to the bolt 13 and the second support plate 17 is slidably connected to the bolt 13.

[0041] In this embodiment, in the initial state, the bolt 13 is fully screwed into the positioning sleeve 12, and the end of the bolt 13 abuts against the side wall of the support column 10, so that the positioning sleeve 12 is located in the through groove 15. Then the bolt 13 is loosened, and under the action of the compression spring 18, the positioning sleeve 12 abuts against the outer wall of the insulated water tank 2, thereby positioning the insulated water tank 2. Then the bolt 13 is threaded through the insulation pad 3 and connected to the first support plate 16. In this way, the thrust generated by the compression spring 18 pushes the positioning sleeve 12 to contact the side wall of the insulated water tank 2, and at the same time the tension generated in the opposite direction pulls the bolt 13 through the first support plate 16 to make it fit tightly against the insulation pad 3, thereby positioning and fixing the insulation pad 3.

[0042] The humidification mechanism is further optimized by including a water supply pipe 19 fixedly connected to the bottom surface of the shading cover 1. Several branch pipes 20 are fixedly connected to the water supply pipe 19 at equal intervals. Atomizing nozzles 21 are installed at the ends of the branch pipes 20 respectively. A cover plate 22 is fixedly connected to the bottom surface of the shading cover 1 through a connecting rod 23. The cover plate 22 is located below the atomizing nozzles 21. The cover plate 22 is arranged in an inverted V-shaped structure. Several through holes are arranged at equal intervals on the cover plate 22. A connecting pipe 7 passes through the shading cover 1 and is fixedly connected to the water supply pipe 19.

[0043] In this embodiment, the water source for atomization is directly the water from the insulated box, thereby ensuring that the water mist entering the germination box will not affect the temperature inside the germination box, ensuring a stable seedling environment. At the same time, the cover plate 22 can prevent the water mist from directly contacting the seeds on the seedbed, reducing the disturbance to the air and improving the seed germination rate.

[0044] The scheme is further optimized. The temperature and humidity monitoring mechanism includes a temperature sensor 24 and a humidity sensor 25 installed on the inner wall of the transparent enclosure 11 and the inner wall of the water storage tank 4. The temperature sensor 24 and the humidity sensor 25 are electrically connected to the host computer.

[0045] Temperature sensor 24 and humidity sensor 25 are used to detect the temperature and humidity of the germination box, thereby ensuring a constant temperature and humidity environment for seedling cultivation.

[0046] The host computer can be configured according to the specific usage environment. For example, it can be controlled by a microcontroller or by a PLC, ARM (Advanced RISC Machine), FPGA (Field-Programmable Gate Array), etc. This embodiment does not make specific limitations.

[0047] The solution is further optimized. The visual monitoring component includes a high-definition camera 26 fixedly connected to the inner wall of the transparent enclosure 11. The high-definition camera 26 is electrically connected to the host computer. A supplementary light 27 is installed at the bottom of the inner wall of the transparent enclosure 11. The supplementary light 27 is correspondingly set with the high-definition camera 26.

[0048] In this embodiment, the high-definition camera 26 can detect the inside of the germination box when the device is completely closed, thereby understanding the seedling situation. It should be noted that the supplemental light 27 uses soft light and shines directly on the bottom of the germination box to avoid shining the seedling bed.

[0049] The design has been further optimized by installing a pressure relief valve on the insulated water tank 2.

[0050] In this embodiment, the insulated water tank 2 is heated by a heater. The insulated water tank 2 is connected to an external water source to ensure the water storage level. The pressure relief valve allows water to be pumped out of the insulated water tank 2. The heater needs to constantly monitor the water level in the insulated water tank 2 to ensure that the temperature of the insulated water tank 2 remains relatively constant.

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.
