Description

Technical Field

[0001] This utility model belongs to the field of seedling tray technology and relates to a seedling device for rice cultivation. Background Technology

[0002] Rice is a staple food crop for humans. The traditional method of rice seedling cultivation involves soaking the seeds until they begin to germinate, followed by field management. However, the fields are often moistened by rainwater, which can cause the soil to become compacted, preventing the rice seedlings from growing vigorously. To save on seed usage, reduce production costs, ensure uniform seedling emergence, and facilitate centralized management, a more comprehensive approach is needed.

[0003] Most existing rice seedling trays have a flat, plate-like structure, with the trays tightly packed together in the water tank, resulting in insufficient air contact between the seedlings and the soil. Furthermore, after the seedlings are raised, they need to be removed from the trays one by one. Currently, the removal method involves taking them out from the top of the tray, which requires overcoming the gravity of the soil to remove the seedlings. Soil easily sticks to the seedling tray's groove, making the removal of seedlings time-consuming, laborious, and prone to damaging the seedlings.

[0004] To address the aforementioned problems, this utility model proposes a seedling raising device for rice cultivation. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a seedling raising device for rice cultivation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a seedling raising device for rice cultivation, comprising a support plate, wherein the support plate is hollowed out;

[0007] Several seedling frames are arranged side by side on the support plate; each seedling frame has a seedling trough extending through it along its height, and the seedling trough is shaped to be smaller at the top and larger at the bottom.

[0008] A drainage baffle is installed between the support plate and the plurality of seedling frames, and the drainage baffle has a lower drainage hole adapted to the plurality of seedling frames.

[0009] A pressure partition is located at the upper end of several seedling frames. The pressure partition is provided with a pressure part that is adapted to each of the several seedling frames. The pressure part is hollow and extends into the seedling trough along the upper end of the seedling trough.

[0010] The clamping mechanism secures the support plate, several seedling frames, drainage partitions, and pressure partitions together.

[0011] Furthermore, the support plate includes several ventilation chambers, and each of the ventilation chambers is adapted to one of the seedling frames; the side wall of the support plate is evenly provided with ventilation slots that communicate with the ventilation chambers.

[0012] Furthermore, the drainage baffle is provided with a number of limiting protrusions at equal intervals, and the number of limiting protrusions is adapted to the number of seedling frames; the limiting protrusions can extend into the seedling trough accordingly.

[0013] Furthermore, the pressing part includes a water collection tank, and the bottom of the pressing part is provided with an upper drainage hole and a seedling exposure hole that are connected to the water collection tank.

[0014] Furthermore, the clamping mechanism includes multiple clamping components, which are respectively located at the four corners of the support plate, the drain baffle, and the lower pressure baffle and are fixed thereto.

[0015] Furthermore, the fastening component includes a first connecting arm, a second connecting arm, a third connecting arm, a limiting sleeve, a fastening bolt, and a fastening nut; the first connecting arm is mounted on the support plate, the second connecting arm is mounted on the leaking baffle, the third connecting arm is mounted on the pressing baffle, the limiting sleeve is positioned between the second connecting arm and the third connecting arm, and the fastening bolt passes through the third connecting arm, the limiting sleeve, the second connecting arm, and the first connecting arm in sequence and is fastened to the fastening nut.

[0016] Compared with the prior art, this utility model has the following advantages: In this utility model, the seedling tray is shaped like a top that is smaller than the bottom by combining the support plate, the seedling frame, the drainage partition, and the pressure partition. When it is necessary to remove the seedlings, force is applied to the soil from the top of the seedling tray, causing the soil to carry the seedlings from the bottom of the seedling tray out of the seedling frame. By removing the seedlings downwards, the force is applied to the soil, making it easier to apply force to remove the soil carrying the seedlings from the bottom of the seedling tray. This saves time and effort and does not damage the seedlings. Attached Figure Description

[0024] 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.

[0025] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: a seedling raising device for rice planting, including a support plate 1, several seedling frames 2, a water-draining partition 3, a pressing partition 4, and a clamping mechanism.

[0026] In this embodiment, the support plate 1 is hollowed out, which improves the drainage of seedlings placed in the seedling frame 2 and improves the air and soil aeration, so that the seedlings can be fully exchanged with the air, promoting the respiration and development of the seedling roots.

[0027] In this embodiment, several seedling frames 2 are arranged side by side on the support plate 1 to facilitate modular cultivation and management of seedlings.

[0028] In this embodiment, a seedling tray 21 is provided through the seedling frame 2 along its height, and the seedling tray 21 is shaped like a small top and a large bottom. When it is necessary to remove the seedlings, force is applied to the soil from the top of the seedling tray 21, so that the soil carries the seedlings out of the seedling frame 2 from the bottom of the seedling tray 21. By removing the seedlings downwards, the force point is applied to the soil, which makes it easier to apply force to remove the soil carrying the seedlings out from the bottom of the seedling tray 21. This saves time and effort and will not damage the seedlings.

[0029] In this embodiment, the pressure partition 4 is located above the seedling frame 2. The pressure partition 4 has an integrally formed pressure part 41 that adapts to each of the seedling frames 2. The pressure part 41 is hollowed out and extends into the seedling trough 21 along its upper end. When it is necessary to remove the seedlings from the seedling trough 21, the pressure part 41 abuts against the soil carrying the seedlings, pushing the soil and removing the seedlings. The hollowed-out design of the pressure part 41 facilitates air entry into the seedling trough 21, allowing for sufficient air exchange between the seedlings and the air. It also allows the seedling stems to protrude through the hollowed-out portion, thus improving the seedling survival rate.

[0030] In this embodiment, the seedling tray 21, the drainage partition 3, and the pressure partition 4 within the seedling frame 2 form a space for storing seedling soil. Each seedling frame 2 has its own space, and the drainage partition 3 and the pressure partition 4 prevent the roots of adjacent seedlings from tangling together, ensuring that each seedling can be smoothly removed from the seedling tray 21. At the same time, the drainage partition 3 and the pressure partition 4 prevent soil loss from the seedling tray 21, ensuring the survival rate of the seedlings.

[0031] In this embodiment, the support plate 1, several seedling frames 2, drainage partition 3, and pressing partition 4 are fixed together by a clamping mechanism to ensure the overall stability of the seedling device.

[0032] In this embodiment, the support plate 1 includes several ventilation chambers 11, which are adapted to several seedling frames 2 one by one, and the ventilation chambers 11 correspond to and communicate with the lower drainage holes 31 on the drainage partition 3; ventilation slots 12 are evenly distributed on the side wall of the support plate 1, which communicate with the ventilation chambers 11. Air is ventilated into the ventilation chambers 11 through the ventilation slots 12 and enters the seedling troughs 21 through the lower drainage holes 31, where it exchanges air with the roots of the seedlings in the seedling troughs 21.

[0033] In this embodiment, a plurality of limiting protrusions 32 are evenly spaced on the drainage baffle 3. These limiting protrusions 32 are adapted to a plurality of seedling frames 2, and can extend into the seedling trough 21. The seedling frames 2 are pre-installed on the drainage baffle 3 via the corresponding limiting protrusions 32. It should be noted that the limiting protrusions 32 do not affect the normal use of the lower drainage hole 31. Of course, for ease of modular management, the plurality of seedling frames 2 can be installed as a single unit to improve installation efficiency.

[0034] In this embodiment, the pressing part 41 protrudes along the surface of the pressing partition 4 so that it can smoothly extend into the seedling trough 21 from the upper end, thereby pushing the soil and allowing the seedlings to detach smoothly from the seedling trough 21. The protruding pressing part 41 forms a water collection trough 411, which can temporarily store the collected fertilizer water for the seedlings to use. The bottom of the pressing part 41 has an upper drainage hole 412 and a seedling exposure hole 413 that are connected to the water collection trough 411. The fertilizer water can enter the seedling trough 21 through the upper drainage hole 412 and the seedling exposure hole 413. The seedling stalks protrude from the seedling trough 21 through the seedling exposure hole 413. It should be noted that the seedling exposure hole 413 is preferably located at the middle of the bottom of the pressing part 41, and its diameter is much larger than the outer diameter of the cultivated seedling so that the seedlings can detach from the seedling exposure hole 413.

[0035] In this embodiment, the clamping mechanism includes multiple clamping components, which are located at the four corners of the support plate 1, the water leakage baffle 3, and the lower pressure baffle 4 and are fixed thereto.

[0036] In this embodiment, the fastening component includes a first connecting arm 51, a second connecting arm 52, a third connecting arm 53, a limiting sleeve 54, a fastening bolt 55, and a fastening nut 56. The first connecting arm 51 is integrally formed on the support plate 1, the second connecting arm 52 is integrally formed on the drainage partition 3's receiving compartment, and the third connecting arm 53 is integrally formed on the pressing partition 4. When assembling the support plate 1, seedling frame 2, drainage partition 3, and pressing partition 4, the limiting sleeve 54 is installed between the second connecting arm 52 and the third connecting arm 53. The fastening bolt 55 passes sequentially through the third connecting arm 53, the limiting sleeve 54, the second connecting arm 52, and the first connecting arm 51, and is fastened with the fastening nut 56. In this state, due to the action of the limiting sleeve 54, the pressing part 41 of the pressing partition 4 only slightly extends into the seedling trough 21, without affecting the growth of the seedlings.

[0037] In this embodiment, several seedling frames 2 are set up as a whole for convenient modular management.

[0038] When seedlings need to be cultivated: First, place the drainage partition 3 on the support plate 1; then install the modular seedling frame 2 one by one on the drainage partition 3 through the corresponding limiting protrusion 32; then place the seedling seeds and soil one by one into the seedling trough 21; then place the pressing partition 4 on the seedling frame 2 and let the pressing part 41 extend into the corresponding seedling trough 21 one by one; then place the limiting sleeve 54 between the second connecting arm 52 and the third connecting arm 53, and the fastening bolt 55 passes through the third connecting arm 53, the limiting sleeve 54, the second connecting arm 52, and the first connecting arm 51 in sequence and is fastened with the fastening nut 56; then pour fertilizer water onto the pressing partition 4, the fertilizer water flows into the water collection tank 411, and enters the seedling trough 21 through the upper drainage hole 412 and the seedling exposure hole 413, and the excess fertilizer water is discharged through the seedling trough 21 and the lower drainage hole 31.

[0039] When it is necessary to remove the seedlings: First, loosen the fastening bolts 55 and fastening nuts 56; then press down the lower partition 4 while lifting the modular seedling frame 2 upward; several seedlings with soil will detach from the seedling trough 21 and fall onto the drainage partition 3; then move the modular seedling frame 2 and the lower partition 4 upward and detach the seedlings.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
