Description

Technical Field

[0001] This invention relates to the field of seedling cultivation and breeding technology, specifically to a highly efficient and automated seedling cultivation device for forestry engineering that optimizes seedling cultivation results. Background Technology

[0002] With the development of technology, hydroponic seedling cultivation in forestry has gradually become large-scale. In the process of automated hydroponic seedling cultivation in forestry, the quality of water has a direct impact on the survival rate. However, the existing hydroponic seedling cultivation equipment in forestry cannot effectively guarantee water quality. During the cultivation process, sediment and root rot will quickly decompose, directly affecting the internal water quality. Filtration and water circulation structures can only achieve a certain effect in filtering out floating impurities, but cannot deal with fallen and rotten roots. At the same time, the circulation filtration structure cannot achieve the best filtration effect on the excrement that settles to the bottom. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] The present invention provides a highly efficient and automated seedling raising device for forestry engineering that optimizes seedling raising effects. Internally, it incorporates a highly efficient, large-scale oxygenation and flow guiding structure. During the aquaculture process, multiple sets of fixedly arranged flow guiding and oxygenating pipes within the flow guiding and oxygenating mechanism, along with multiple sets of flow guiding fan blades on the outer side of these pipes, enable the flow guiding fan blades to rotate during internal airflow, thereby driving the internal water flow. Simultaneously, the arrayed flow guiding and oxygenating pipes and vertically distributed flow guiding fan blades significantly optimize the distribution of seedlings within the hydroponic seedling raising pond, preventing seedling rot. The accumulation and dense distribution of roots can lead to oxygen deficiency and other problems that affect survival rates. However, the function of the flow-guiding and oxygenation mechanism is connected by the outer ring plate and the load-bearing rod, and an internal air transmission channel is set up. The flow-guiding and oxygenation pipes are equipped with oxygenation holes for oxygenation gas output. With the uniform array distribution of the flow-guiding and oxygenation pipes, the water in the hydroponic seedling pond can be oxygenated in all directions. In addition, the oxygenation structure, together with the setting of the flow-guiding fan blade plate, can prevent roots from sticking together and accumulating. At the same time, it is also conducive to increasing the oxygen intake of seedling roots during the cultivation process and avoiding root burn.

[0017] The present invention provides a highly efficient and automated seedling raising device for forestry engineering that optimizes seedling raising effects. The device includes a bottom-circulation recycling and treatment mechanism. This mechanism consists of a fixed docking and retraction long box and a long box driven by a rotating end seat. A drive motor starts the drive shaft and rotating end seat, causing the long box to rotate. Through the forward-facing recycling storage chamber and the front docking plate of the long box, excrement and other impurities are moved into the recycling storage chamber during rotation. The front docking plate, in contact with the bottom wall of the hydroponic seedling raising pool, moves these impurities into the recycling storage chamber. A fine filter screen is installed on the rear end wall of the recycling storage chamber to ensure water flow while reducing resistance and preventing impurities from passing through. Simultaneously, metabolic impurities and detached roots are collected during rotation and blocked by a partition door. The separator, positioned in front of the temporary storage chamber, prevents the seedlings from being collected in the front cavity. After rotating nearly one revolution, the seedlings enter the rearward cavity of the re-drawing long box via the front connection of the long box. This merges the long box with the re-drawing long box. Once the re-drawing pump is activated, re-drawing air pressure is generated through the re-drawing port. This air pressure causes the sealing separator to open backward while rotating towards the re-drawing long box. During this process, metabolic impurities and detached roots are pushed into the re-drawing long box. The re-drawing effect also draws impurities and seedlings from the long box back to the filter discharge box for interception. These are then collected in the storage chamber through the discharge port at the bottom of the filter discharge box. This prevents sediment and detached roots from remaining in the water for extended periods, thus avoiding problems with the health of the water and the seedlings inside. Attached Figure Description

[0038] Specific usage of this invention:

[0039] In use, the hydroponic seedlings are placed in the hydroponic seedling pool 11 after the roots are fixed by the hydroponic frame. The water circulation port on the side of the hydroponic seedling pool 11 is connected to the external circulation equipment to realize the circulation and filtration of the internal hydroponic solution during the breeding process.

[0040] The efficient and automated seedling raising device for forestry engineering, which optimizes seedling raising effects according to the present invention, is equipped with a highly efficient and wide-range oxygenation and flow guiding structure. During the aquaculture process, multiple sets of fixedly arranged flow guiding and oxygenation pipes 26 in the flow guiding and oxygenation mechanism 20, and multiple sets of flow guiding fan blades 28 arranged on the outside of the flow guiding and oxygenation pipes 26, can drive the flow guiding fan blades 28 to rotate during the internal airflow, thereby driving the internal water flow. At the same time, the arrayed flow guiding and oxygenation pipes 26 and the vertically distributed flow guiding fan blades 28 can greatly optimize the distribution of seedlings in the water-based seedling raising pond 11, avoiding seedling rot. Accumulation and dense distribution can lead to oxygen deficiency and other problems affecting survival rates.

The flow-guiding oxygenation pipe 26 is equipped with oxygenation holes 27 for oxygenation gas output. With the uniform array distribution of the flow-guiding oxygenation pipe 26, the water in the hydroponic seedling pond 11 can be oxygenated in all directions. In addition, the oxygenation structure, together with the setting of the flow-guiding fan blade plate 28, can prevent the roots from sticking together and accumulating. At the same time, it is also conducive to increasing the oxygen intake of the seedling roots during the cultivation process and avoiding root burn.

[0041] The efficient automated seedling raising device for forestry engineering, which optimizes seedling raising effects according to the present invention, is equipped with a bottom circulation and recycling mechanism. This recycling mechanism 30 consists of a fixedly mounted docking and retraction elongated box 40 and a recycling elongated box 34 driven to rotate by a rotating end seat 31. The drive motor 21 starts the drive shaft 29 and the rotating end seat 31, causing them to rotate. Through the forward-facing recycling storage chamber 35 and the front docking plate 39 of the recycling elongated box 34, excrement and other impurities are moved into the recycling storage chamber 35 during rotation. The docking plate 39, in contact with the bottom wall of the hydroponic seedling pool 11, moves these impurities into the recycling storage chamber 35. A fine filter screen 55 is installed on the rear end wall of the recycling storage chamber 35 to ensure water flow while reducing resistance. Simultaneously, it prevents impurities from passing through. During the rotation process, metabolic impurities and detached roots are collected and blocked by the partition door 37 at the front of the recycling temporary storage chamber 35. While the partition door 37 blocks these seedlings from being collected in the front cavity of the recycling temporary storage chamber 35, after rotating nearly one revolution, the seedlings are joined to the rear cavity of the docking and return long box 40 through the front of the recycling long box 34. This merges the recycling long box 34 with the docking and return long box 40. After the return pump 52 is started, return air pressure is generated through the return port 41. Under the influence of air pressure, the sealing partition door 58 opens rearward while the partition door 37 rotates towards the docking and return long box 40. During this process, metabolic impurities and detached roots are pushed into the docking and return long box 40. The internal drive, combined with the back-pull effect, causes impurities and seedlings in the long box 34 to be drawn back from the back-pull port 41 to the filter discharge box 53 for interception. They are then placed in the storage chamber 49 through the discharge port at the bottom of the filter discharge box 53 for collection. This avoids the problem of sedimented impurities and detached roots remaining in the water for a long time, which could affect the health of the water and the seedlings inside.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
