Description

Technical Field

[0001] This utility model relates to the field of seed soaking equipment technology, specifically to a seed soaking and germination seedling raising device. Background Technology

[0002] The main reasons for soaking seeds before sowing include promoting germination, softening the seed coat, and sterilization. Soaking activates cell metabolism by increasing the free soaking solution content, shortening germination time; it also softens the seed coat, breaks dormancy, and creates favorable conditions for seed germination. Soaking allows seeds to absorb the soaking solution, increasing the free soaking solution content, promoting cell metabolism, and helping seeds break dormancy and begin germination more quickly. For example, peony seeds require freezing to break dormancy, while most crops can achieve a similar effect through soaking. For some crops with thick seed coats or a dormant period, soaking softens the seed coat and activates internal physiological activities, making it easier for the embryo to break through the seed coat. Soaking in warm solution can kill pathogens and insect eggs on the seed surface, reducing the threat of pests and diseases to seedlings.

[0003] In agricultural planting, such as rice, cotton, and vegetable planting, soaking seeds before planting is an important process. For seeds that germinate slowly, soaking them before sowing can promote earlier germination and also kill harmful insect eggs and viruses.

[0004] Chinese utility model patent application number CN202223005327.7 discloses a seed soaking container for rice seed soaking. During the seed soaking process, a large number of seeds need to be placed in the seed soaking solution tank. After soaking for a certain period of time, the plump seeds will sink, while the shriveled and insect-damaged seeds will float. When there are a large number of seeds, after being put into the seed soaking solution tank, the seeds sometimes clump together. The shriveled and insect-damaged seeds are squeezed and do not easily float, resulting in incomplete removal of bad seeds. Furthermore, the clumping together makes it inconvenient to remove the already suspended bad seeds. Utility Model Content

[0041] Those skilled in the art should understand that the accompanying drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily essential for implementing this utility model.

[0042] like Figures 1 to 8As shown, this embodiment provides a seed soaking and germination device, including: a fixed box 1; a box door 2 is pivotally connected to one side of the fixed box 1; multiple seed soaking boxes 3 are arranged sequentially from top to bottom inside the fixed box 1; the seed soaking boxes 3 store seeds to be soaked, and each seed soaking box 3 is connected to an inlet branch pipe 4 and an outlet branch pipe 5. In specific application, the soaking solution enters the seed soaking box 3 through the inlet branch pipe 4 to soak and germinate the seeds in the seed soaking box 3. After use, the soaking solution is discharged through the outlet branch pipe 5. After soaking is completed, the box door 2 is opened and the seeds in the seed soaking box 3 are taken out.

[0043] To ensure thorough soaking of the seeds and improve soaking efficiency by agitating the seed soaking solution within the soaking tank 3, a stirring rod 9 is installed in each soaking tank 3. This stirring rod 9 agitates the mixture of seeds and soaking solution within the tank, accelerating the soaking process. Specifically, a drive device 6 is located at the top of the fixed tank 1. This drive device 6 drives a rotatable conveying pipe 7 that extends into the fixed tank 1; the drive device 6 rotates the conveying pipe 7. The conveying pipe 7 passes through multiple soaking tanks 3 sequentially and extends out to the bottom of the fixed tank 1, connecting to a conveying pump 8. In practical applications, the drive device 6 can be a servo motor.

[0044] Each of the soaking tanks 3 is equipped with a collection shell 10. Both the stirring rod 9 and the collection shell 10 are connected to the conveying pipe 7 and rotate with it. The stirring rod 9 is located near the bottom of the soaking tank 3, and the collection shell 10 is located near the top of the soaking tank 3, and the collection shell 10 is connected to the conveying pipe 7. During the rotation of the conveying pipe 7, the stirring rod 9 slowly stirs at the bottom of the soaking tank 3. Defective seed shells, impurities, etc., can be suspended near the surface of the soaking liquid or float on the surface. Under the action of the conveying pump 8, the empty shells, impurities, etc., are collected by the collection shell 10 along with the flow of the soaking liquid and sent into the conveying pipe 7, where they are transported to the outside by the conveying pump 8. Simultaneously, to ensure sufficient soaking liquid in the soaking tank 3, the inlet branch pipe 4 continuously supplies soaking liquid.

[0045] In one specific embodiment, combined with Figure 5 , Figure 6 As shown, the collecting shell 10 is rectangular, and one side of the collecting shell 10 is a collecting port 36. The driving device drives the conveying pipe to rotate in the same direction as the opening direction of the collecting port 36. During the rotation, empty shells, impurities, etc. can enter the collecting shell 10 through the collecting port 36 and then flow into the conveying pipe from the collecting shell 10.

[0046] In one specific embodiment, combined with Figure 2 , Figure 4 , Figure 7As shown, the soaking tank 3 includes a fixed shell 11 fixed inside the fixed box 1, and a support shell 16 mounted on the fixed shell 11. A storage shell 13 is movably inserted into the support shell 16, and the support shell 16 and the storage shell 13 together form a soaking space. Seeds and soaking solution can be stored in the soaking space, where the seeds undergo soaking. The fixed shell 11 includes a bottom shell 14 fixed inside the fixed box 1. One side of the bottom shell 14 is a liquid storage shell 15, and one side of the liquid storage shell 15 is a movably mounted support shell 16 on the bottom shell 14. The liquid storage shell 15 is connected to the liquid outlet branch pipe 5, and the support shell 16 is connected to the liquid inlet branch pipe 14; the bottom of the support shell 16 is provided with a drain hole 17. The supporting shell 16 includes a bottom plate 18 with the drainage hole 17 and a baffle 19 on the bottom plate 18. The baffle 19 is semi-enclosed on the bottom plate 18, with an opening 20 on one side and grooves 21 on both sides of the opening 20 for the insertion of the storage shell 13. A connecting hole 33 is provided on the baffle 19, which is connected to the inlet branch pipe 4. The soaking solution enters the supporting shell 16 through the connecting hole 33 via the inlet branch pipe 4 and is stored in the soaking space formed by the storage shell 13 and the supporting shell 16, where the seeds are soaked. After the seeds have soaked, the storage shell 13 is slowly pulled out from the supporting shell 16, and the soaking solution is discharged from the bottom plate 18 of the supporting shell 16 to the bottom plate 18 and the storage shell 15. A connecting hole (not shown in the figure) is also provided on the side plate of the storage shell 15, which is connected to the outlet branch pipe 5, through which the soaking solution is discharged.

[0047] Specifically, the storage shell 13 includes a support plate 22 that matches the semi-enclosed shape formed by the baffle 19, and a plug-in shell 23 connected to one side of the support plate 22 corresponding to the opening 20. The outer side of the plug-in shell 23 is opposite to the box door 2, and the two sides of the plug-in shell 23 are slidably connected to the sliding grooves 21 on both sides of the opening 20. The support plate 22 can fit and match the bottom plate 18 and the baffle 19. The support plate 22 can be inserted into the top of the bottom plate 18 through the opening. The two sides of the plug-in shell 23 are slidably matched with the sliding grooves 21. When the support plate 22 and the plug-in shell 23 are plugged and matched with the support shell 16, the support shell 16 and the storage shell 13 together form a soaking space.

[0048] In one specific embodiment, to facilitate the extraction of the storage shell 13, the conveying pipe 7 includes branch pipes 25 connected sequentially via multiple adapters 24; each adapter 24 connects two adjacent branch pipes 25, one end of the uppermost branch pipe 25 is connected to the output shaft of the drive device 6, and one end of the lowermost branch pipe 25 is connected to the conveying pump 8. Wherein, combined with Figure 8As shown, the adapter 24 includes a rotatable adapter pipe 26 located in the middle of the support plate 22, with each end of the adapter pipe 26 detachably connected to a branch pipe 25. Specifically, to achieve a rotatable connection between the adapter pipe 26 and the support plate, a mounting hole 31 is provided in the middle of the support plate 22, and a sealing bearing 32 is provided inside the mounting hole 31, with the adapter pipe 26 arranged within the inner ring of the sealing bearing 32. To achieve a detachable connection between the adapter pipe 26 and the branch pipe 25, each end of the adapter pipe 26 extending beyond the two sides of the support plate 22 is provided with a locking platform 27. The two locking platforms 27 are positioned correspondingly. At the other end of the topmost branch pipe 25, the other end of the bottommost branch pipe 25, and both ends of the other branch pipes 25, there are locking grooves 28 that mate with the locking platforms 27. The locking grooves 28 slide and engage with the locking platforms 27, thus achieving communication and detachable connection between the branch pipe 25 and the adapter pipe 26. When it is necessary to remove the storage shell, the locking platforms 27 and locking grooves 28 can be removed. The detachable connection between the support shell and the storage shell facilitates cleaning and maintenance of the device.

[0049] To achieve a rotatable connection between the branch pipe 25 and the bottom shell 14 and the bottom plate 18, mounting holes 31 can also be provided in the middle of the bottom shell 14 and the bottom plate 18. A sealed bearing (not shown in the figure) is installed in the mounting hole 31, and the branch pipe is fixedly connected to the inner ring of the sealed bearing, thus achieving a rotatable connection between the branch pipe and the bottom shell 14 and the bottom plate 18. To facilitate the insertion and removal of the storage shell 13, two grooves 29 are provided on the outer side of the insertion shell 23, and handles 30 are provided in the grooves 29. Users can easily insert and remove the storage shell by holding the two handles 30. The plug-in shell 23 and the support plate 22 are detachably connected to ensure that the plug-in shell 23 can be removed separately to facilitate the placement of seeds to be soaked on the support plate 22. Specifically, the detachable connection can be achieved by bolts (not shown in the figure). For example, a threaded hole is provided on the outer wall of the plug-in shell, and a corresponding threaded hole is provided on the side of the support plate 22. The support plate 22 and the plug-in shell 23 are detachably connected by bolts that fit into the threaded holes.

[0050] In the specific use of the seed soaking and germination device described in this embodiment of the invention, first open the box door 2, remove the connector shell 23 from the support plate 22, place the seeds to be soaked on the support plate 22, then insert the connector shell 23 into the opening 20 and install it on the support plate 22, close the box door, and connect the external liquid inlet pump (not shown in the figure) to the main liquid inlet pipe 34, which in turn connects to the branch liquid inlet pipes. The soaking solution is pumped into the main liquid inlet pipe 34 by the liquid inlet pump (not shown in the figure), and then enters the soaking space through the branch liquid inlet pipes. The seeds are soaked. During the soaking process, the drive device 6 can be turned on to rotate the conveying pipe 7. The rotation of the conveying pipe 7 drives the stirring rod 9 to rotate, which agitates the soaking solution in the soaking space, improving the soaking efficiency. The drive speed of the drive device 6 does not need to be too fast, just enough to ensure that the seeds do not sink to the bottom and accumulate. During the agitation, empty shells or impurities will float to the top and be collected by the collection shell 10 into the conveying pipe 7. The conveying pump 8 will then pump them to the external collection tank (not shown in the figure) for further processing. After soaking is completed, the drive device is turned off, the conveying pipe stops rotating, the box door is opened, and the plug shell 23 along with the support plate 22 is slowly pulled out by holding the two handles 30 until the drain hole 17 leaks out. The soaking solution flows from the drain hole 17 to the bottom shell, flows into the outlet branch pipe through the connecting hole on one side of the liquid storage shell, and then converges into the outlet main pipe 35 by the outlet branch pipe 4. The outlet pump (not shown in the figure) will then pump the solution to the soaking solution collection tank for further reuse or other processing.

[0051] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that, based on the technical solutions disclosed in the present utility model, all modifications or variations that can be made by those skilled in the art without creative effort should be included within the scope of protection of the present utility model.
