Abstract
Description
Technical Field
[0001] This utility model relates to the field of forestry seedling cultivation, specifically to a layered forestry seedling cultivation device. Background Technology
[0002] When sowing seedlings in forestry, it is necessary to fill the seedling trays with substrate. The prepared substrate is then filled into the holes of the trays, and after filling, it is leveled with a scraper or wooden board to ensure a uniform substrate height in each hole. After filling the substrate, the seedling trays need to be pressed into the holes. Different seeds have different sowing depth requirements, and it is difficult to precisely control the depth of each hole to perfectly match the optimal sowing depth for the seed. If the holes are pressed too deep, the seeds may have difficulty germinating due to the thick soil cover, and the poor aeration of the deep soil can lead to oxygen deficiency, affecting germination. If the holes are pressed too shallow, the seeds are easily exposed to the air, making it difficult to retain moisture and making them more susceptible to environmental factors such as temperature fluctuations and drying out, which is also detrimental to germination.
[0003] Meanwhile, improper tools or operating methods during the pressing process may damage the seedling trays. For example, excessive force may deform the holes in the tray, affecting subsequent seed placement and seedling growth space. Furthermore, deformed holes may lead to uneven substrate filling, indirectly affecting seed germination and seedling root development. Moreover, after pressing, sowing is required, placing one seed per hole in the pressed tray to avoid omissions. The tray is then covered with substrate. For large-scale seedling production, manual sowing is relatively slow. Mechanical sowing, on the other hand, involves higher equipment costs. Utility Model Content
[0004] This invention addresses the problem that existing seedling trays often struggle to precisely control the depth of each hole to match the optimal sowing depth for the seeds, which can lead to seed hypoxia due to excessive soil cover and impaired germination. Therefore, this invention provides a layered forestry seedling raising device.
[0005] The technical solution of this utility model is:
[0006] A layered forestry seedling raising device comprises a tray box and seedling trays. The seedling trays are installed inside the tray box, and the bottom of the tray box supports the bottom of the seedling trays. Each seedling tray has a set of plug trays arranged in a rectangular array. The tray box is equipped with a perforated plate and a seeding plate. The perforated plate is positioned above the seedling trays, and the seeding plate is positioned above the perforated plate. The perforated plate and the seeding plate work together to form a plug tray sowing assembly, which enables sowing in each plug tray of the seedling trays.
[0007] The tray box is also equipped with a layered board, and there is at least one layered board. The layered board is positioned above the seedling tray and is used to cover each seedling tray with soil.
[0008] The tray box has rectangular soil drainage holes symmetrically opened on both sides. The top end face of the seedling tray is higher than the bottom surface of the soil drainage hole. The soil drainage holes of the tray box allow excess substrate and seeds above the seedling tray to be discharged.
[0009] Furthermore, the perforated plate has a rectangular structure and is laid on top of the seedling tray;
[0010] The perforated plate has a set of seed dropping holes arranged in a rectangular array, and the center of the seed dropping holes of the perforated plate is on the same Y-axis as the center of each cell of the seedling tray.
[0011] Furthermore, the seeding plate is laid flat on top of the perforated plate, the seeding plate is L-shaped, and there is a gap between the longitudinal surface of the seeding plate and the inner side of the tray box.
[0012] The seeding plate has a set of tapered holes arranged in a rectangular array, with a large opening at the top and a small opening at the bottom.
[0013] Furthermore, the diameter of the seed drop holes in the perforated plate and the conical holes in the sowing plate is larger than the size of the seeds.
[0014] Furthermore, when there is a gap between the longitudinal plate surface of the seeding plate and the inner side of the tray box, the seed dropping holes of the perforated plate and the conical holes of the seeding plate are arranged alternately.
[0015] When the longitudinal plate of the seeding plate approaches the inner side of the tray box, the seed dropping holes of the perforated plate and the conical holes of the seeding plate are on the same Y-axis.
[0016] Furthermore, the layered plate has a rectangular structure, and a set of substrate drainage holes are formed in a rectangular array on the layered plate. The diameter of the substrate drainage holes is the same as the maximum diameter of the plug tray on the seedling tray.
[0017] Furthermore, the depth of the substrate drainage holes in the layered plate is equal to the thickness of the substrate covering soil above the seedling tray;
[0018] A scraper is vertically installed on the layered plate. The scraper slides horizontally above the layered plate to discharge the substrate above the layered plate through the soil discharge hole of the pallet box.
[0019] Furthermore, the length and width of the perforated plate and the layered plate are the same as the length and width of the seedling tray;
[0020] The length and width of the perforated plate and the layered plate are the same as the inner length and width of the pallet box, and the pallet box serves to limit the position of the perforated plate and the layered plate.
[0021] Furthermore, a baffle is vertically connected to the inner wall of the pallet box, and the baffle is integrally connected to the pallet box.
[0022] Compared with the prior art, the present invention has the following advantages:
[0023] This invention, through the cooperation of the tray box, seedling tray, and layered board, ensures the substrate depth and guarantees that the seeds are sown at the same depth, thus maintaining relatively consistent temperature, humidity, and oxygen conditions around the seeds. This avoids situations where some seeds are buried too deep, making it difficult for them to obtain sufficient oxygen for respiration and thus preventing germination; or where some seeds are buried too shallow, easily failing to germinate due to excessive moisture loss.
[0024] This invention provides a uniform growth space for seedling roots. During growth, roots need to extend outwards and downwards; a uniform substrate depth allows the roots to naturally spread out in a similar physical environment.
[0025] This invention, through the combination of perforated plates and seeding plates, enables rapid and uniform sowing for large-scale seedling production, which is more efficient than manual sowing.
[0026] This invention eliminates the need for pressing holes in the seedling cultivation process, improves the efficiency of seedling cultivation, and ensures that the thickness of the soil substrate covering each seed is the same, thereby increasing the seed survival rate and facilitating subsequent seedling management.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0045] Specific implementation method one: Combining Figure 1 — Figure 3 This embodiment describes a layered forestry seedling raising device, comprising a tray box 1 and seedling trays 2. The tray box 1 contains the seedling trays 2, and the bottom of the tray box 1 supports the bottom of the seedling trays 2. Each seedling tray 2 has a set of plug trays 3 arranged in a rectangular array. The tray box 1 contains a perforated plate 4 and a sowing plate 5. The perforated plate 4 is positioned above the seedling trays 2, and the sowing plate 5 is positioned above the perforated plate 4. The perforated plate 4 and the sowing plate 5 work together to form a plug tray sowing assembly S, which enables sowing in each plug tray 3 of the seedling tray 2.
[0046] The tray box 1 is also equipped with a layered board 6. There is at least one layered board 6, and the layered board 6 is positioned above the seedling tray 2. The layered board 6 enables the covering of soil for each cell 3 of the seedling tray 2.
[0047] The tray box 1 has rectangular soil discharge holes 7 symmetrically opened on both sides. The top end face of the seedling tray 2 is higher than the bottom hole face of the soil discharge hole 7. The soil discharge hole 7 of the tray box 1 allows excess substrate and seeds above the seedling tray 2 to be discharged.
[0048] Specific Implementation Method Two: Combining Figure 4 — Figure 5 This embodiment describes a layered forestry seedling raising device, wherein the perforated plate 4 has a rectangular structure and is laid on top of the seedling tray 2.
[0049] The perforated plate 4 has a set of seed dropping holes 41 arranged in a rectangular array. The center of the seed dropping holes 41 on the perforated plate 4 is on the same Y-axis as the center of each seedling tray 3 in the seedling tray 2.
[0050] Each seed hole 41 on the perforated plate 4 corresponds to the center of the seed tray 3. When the seed 8 falls from the seed hole 41 on the perforated plate 4, the seed falls directly to the center of each seed tray 3 on the seedling tray 2. The substrate in the seed tray 3 is on the same horizontal plane as the top of the seed tray 3.
[0051] Specific implementation method three: Combining Figure 4 — Figure 5 This embodiment describes a layered forestry seedling raising device, wherein the seeding plate 5 is laid flat on top of the perforated plate 4, the seeding plate 5 has an overall L-shaped structure, and there is a gap between the longitudinal surface of the seeding plate 5 and the inner side of the tray box 1.
[0052] The seeding plate 5 has a set of conical holes 51 arranged in a rectangular array, with a large opening at the top and a small opening at the bottom.
[0053] The width of the seeding plate 5 is the same as the width of the perforated plate 4, and the length of the seeding plate 5 is less than the length of the perforated plate 4. The seeding plate 5 is set in an L-shaped structure to facilitate horizontal movement of the seeding plate 5 above the perforated plate 4.
[0054] Specific implementation method four: Combination Figure 4 — Figure 5 This embodiment describes a layered forestry seedling raising device, wherein the diameter of the seed drop hole 41 of the perforated plate 4 and the conical hole 51 of the sowing plate 5 is larger than the size of the seed 8.
[0055] When the perforated plate 4 and the seeding plate 5 are used together, the seeds are first poured onto the seeding plate 5. The seeds 8 can be pushed horizontally on the seeding plate 5 using the scraper 9. Some of the seeds 8 will fall into the conical holes 51 on the seeding plate 5, with one seed 8 falling into each conical hole 51. When the conical holes 51 of the seeding plate 5 are full of seeds 8, the seeding plate 5 and the seeds 8 in the conical holes 51 of the seeding plate 5 are close to the same horizontal plane. The excess seeds 8 are discharged from the soil discharge hole 7 of the tray box 1 through the scraper 9. After the seeds 8 are completely discharged, the seeding plate 5 is pulled horizontally. The conical holes 51 on the seeding plate 5 will align with the seed drop holes 41 on the perforated plate 4 below. At this time, the seeds 8 in the conical holes 51 on the seeding plate 5 will fall into the seed tray 3 filled with substrate through the seed drop holes 41 on the perforated plate 4, completing the sowing.
[0056] Specific Implementation Method Five: Combining Figure 4 , Figure 5 , Figure 10 and Figure 11 This embodiment describes a layered forestry seedling raising device. When there is a gap between the longitudinal surface of the seeding plate 5 and the inner side of the tray box 1, the seed dropping holes 41 of the perforated plate 4 and the conical holes 51 of the seeding plate 5 are arranged alternately.
[0057] When the longitudinal plate surface of the seeding plate 5 approaches the inner side of the tray box 1, the seed dropping hole 41 of the perforated plate 4 and the conical hole 51 of the seeding plate 5 are on the same Y-axis.
[0058] The seed dropping holes 41 of the perforated plate 4 and the conical holes 51 of the sowing plate 5 are arranged alternately. The above structure can prevent the seeds 8 in the conical holes 51 of the sowing plate 5 from falling directly into the seed tray 3. At the same time, the cooperation between the perforated plate 4 and the sowing plate 5 can quickly complete the seed sowing work.
[0059] Specific Implementation Method Six: Combination Figure 8 — Figure 9 This embodiment describes a layered forestry seedling raising device. The layered plate 6 has a rectangular structure, and a set of substrate holes 61 are arranged in a rectangular array on the layered plate 6. The diameter of the substrate holes 61 is the same as the maximum diameter of the plug tray 3 on the seedling tray 2.
[0060] The layered plate 6 can be multiple layers of different thicknesses. Multiple layers of layered plates 6 can be stacked and used according to different needs. The depth of the substrate holes 61 on the layered plate 6 is the thickness of the substrate laid above the seed tray 3, so as to ensure that the thickness of the soil covering each seed tray 3 is the same.
[0061] Specific implementation method seven: Combination Figure 12This embodiment describes a layered forestry seedling raising device, wherein the depth of the substrate drainage holes 61 in the layered plate 6 is equal to the thickness of the substrate covering soil above the seedling tray 2.
[0062] A scraper 9 is vertically installed on the layered plate 6. The scraper 9 slides horizontally above the layered plate 6 to discharge the substrate above the layered plate 6 through the soil discharge hole 7 of the tray box 1.
[0063] After seeds 8 are placed in each seedling tray 3 of the seedling tray 2, the layering plate 6 is placed above the seedling tray 2, and then the substrate is poured onto the layering plate 6. The substrate on the layering plate 6 is leveled by scraper 9, and the excess substrate is discharged from the soil discharge holes 7 on both sides of the tray box 1.
[0064] Specific implementation method eight: Combination Figure 1 — Figure 15 This embodiment describes a layered forestry seedling raising device, wherein the length and width of the perforated plate 4 and the layered plate 6 are the same as the length and width of the seedling tray 2.
[0065] The length and width of the perforated plate 4 and the layered plate 6 are the same as the inner length and width of the pallet box 1, and the pallet box 1 plays a limiting role for the perforated plate 4 and the layered plate 6.
[0066] The tray box 1 can position the layered plate 6 inside the tray box 1, so that each substrate drop hole 61 on the layered plate 6 aligns with the corresponding seed tray 3. The entire sowing process does not require the pressing of holes, reducing the number of pressing steps. At the same time, it can ensure that the soil covering depth of the seeds sown in the seed tray 3 is consistent.
[0067] Specific Implementation Method Nine: Combining Figure 1 — Figure 15 This embodiment describes a layered forestry seedling raising device, wherein a baffle 10 is vertically connected to the inner wall of the tray box 1, and the baffle 10 is integrally connected to the tray box 1.
[0068] Working principle:
[0069] During seedling cultivation, place the seedling tray 2 inside the tray box 1, pour the substrate onto the seedling tray 2, and use the scraper 9 to horizontally push the substrate across the seedling tray 2 until each cell 3 of the seedling tray 2 is filled with substrate. Excess substrate is pushed to the drainage hole 7 of the tray box 1 to remove it. At this point, each cell 3 of the seedling tray 2 is filled with substrate, and the top is nearly horizontal. Place the perforated plate 4 onto the seedling tray 2, and place the seeding plate 5 above the perforated plate 4. The holes of the conical holes 51 on the seeding plate 5 and the seed holes 41 on the perforated plate 4 are staggered. Sow the seeds 8 onto the seeding plate 5. Some seeds 8 will fall into the conical holes 51 of the seeding plate 5. When each conical hole 51 contains one seed 8, pull the seeding plate 5 horizontally. When pulled a certain distance, the seeds on the seeding plate 5 will... The conical hole 51 of the seeding plate 5 coincides with the seed drop hole 41 of the lower perforated plate 4. At this time, the seeds 8 in the conical hole 51 of the seeding plate 5 fall directly into the middle of each seedling tray 3 in the seedling tray 2 through the seed drop hole 41. The perforated plate 4 and the seeding plate 5 are removed from the tray box 1 in sequence. The layering plate 6 is laid on top of the seedling tray 2, and the substrate is poured onto the layering plate 6. The substrate is pushed into the substrate drop hole 61 of the layering plate 6 by the scraper 9. After the substrate drop hole 61 is filled with substrate, the excess substrate is discharged from the soil discharge hole 7 of the tray box 1 through the scraper 9. At this time, the substrate in the substrate drop hole 61 will cover the seeds in the seedling tray 3 below. The layering plate 6 remains in the tray box 1. Depending on the coverage depth of different substrates, it can continue to be stacked on top of the layering plate 6, thereby ensuring that the substrate thickness of each seedling tray 3 in the seedling tray 2 is the same. The above structure can save the process of pressing the seedlings into holes, improve the efficiency of seedling raising, and at the same time, ensure that the thickness of the substrate covering each seed 8 is the same, thereby improving the seed survival rate.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution.
