Description

Technical Field

[0001] This utility model relates to the field of sweet potato seedling technology, specifically a sweet potato seedling raising device. Background Technology

[0002] Sweet potato seedling cultivation is a key link in ensuring high yield and quality: centralized seedling cultivation allows for precise control of environmental conditions such as temperature, humidity, and light, breaking seed dormancy and accelerating germination, while also selecting healthy seed potatoes to avoid direct infection by soil-borne diseases; intensive management promotes seedling root development.

[0003] In the prior art, such as the sweet potato seedling raising equipment proposed in patent application number "CN201821661644.5", a seedling box and a cover plate are included. The cover plate is detachably fixed on the seedling box. The cover plate is divided into an upper chamber and a lower chamber by a transparent plate. A lamp tube is provided in the upper chamber and a nozzle is provided in the lower chamber. The nozzle is connected to a spray pipe.

[0004] However, in the aforementioned patent application, watering for sweet potato seedlings is done directly from above the soil using a sprinkler head. Direct watering can easily lead to water accumulation in the surface soil, causing seed rot and soil compaction, hindering the emergence of seedlings and increasing the risk of "stunted sprouts". The impact of water flow can easily cause seed displacement or loss of soil covering, reducing the uniformity of seedling emergence. At the same time, water concentrated on the surface inhibits root growth, resulting in shallow roots and poor resistance in seedlings. Utility Model Content

[0005] The purpose of this invention is to provide a small sweet potato seedling raising device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A seedling raising device for sweet potatoes includes a seedling box. The seedling box has a water replenishment tray that can move up and down inside. The water replenishment tray contains clean water for replenishing the sweet potato seedlings. A support frame is set inside the seedling box and above the water replenishment tray. The support frame has evenly spaced annular openings, and seedling trays are set at the annular openings.

[0008] The seedling tray includes a tray body for holding the culture soil and cultivating small sweet potatoes in the culture soil. The tray body passes through the opening on the support frame and extends to the bottom of the support frame. Multiple through holes are opened around the sides and bottom of the tray body. A support ring is fixedly connected to the outer surface of the tray body above the support frame. The support ring is used to restrict the downward movement of the tray body.

[0009] Preferably, the top of the seedling box is equipped with a light-transmitting cover, and the sides of the seedling box are equipped with breathable nets to improve the air permeability inside the seedling box.

[0010] Preferably, the top of the seedling box is fixedly connected to a threaded shaft, the bottom of the water supply tray is provided with a support plate, the bottom of the support plate is rotatably connected to a threaded sleeve, and the threaded sleeve and the threaded shaft are threadedly connected.

[0011] Preferably, the support plate has a positioning slot, and a support block is fixedly connected to the bottom of the water replenishment tray inside the positioning slot.

[0012] Preferably, a guide rod is fixedly connected to the bottom of the inner wall of the seedling box, a sliding block is slidably connected to the guide rod, an inclined connecting rod is rotatably connected to the top of the sliding block, and the top of the inclined connecting rod is rotatably connected to the bottom of the support plate.

[0013] Preferably, both sides of the inner wall of the seedling box are equipped with supporting steel plates, the supporting frame is provided with positioning holes, and a positioning shaft is fixedly connected to the top of the supporting steel plate and inside the positioning hole.

[0014] The beneficial effects of this utility model are:

[0015] This invention involves raising sweet potato seedlings in a seedling tray at a constant height. A water-filled tray inside the tray moves up and down, immersing the seedlings in water from the bottom. Capillary action ensures the substrate is evenly moistened from bottom to top, avoiding direct watering that could lead to surface water accumulation, seed rot, and soil compaction. This keeps the surface of the potting soil loose and porous, making it easier for the seedlings to emerge, reducing the risk of "stunted growth," and promoting deeper root development, resulting in stronger seedlings. It also maintains stable substrate moisture while reducing water on the leaves, thus preventing the spread of soil-borne diseases. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 and Figure 4 A seedling raising device for sweet potatoes includes a seedling box 1 with an openable door (not shown in the figure) on the outside. Inside the seedling box 1 is a water replenishment tray 2 that can move up and down. The water replenishment tray 2 contains clean water for replenishing the sweet potato seedlings. Inside the seedling box 1 and above the water replenishment tray 2, there is a support frame 3. The support frame 3 has evenly spaced annular openings, and seedling trays 4 are set at each annular opening. Each annular opening corresponds to a seedling tray 4.

[0025] The seedling tray 4 includes a tray body 401, which is used to hold the culture soil and cultivate small sweet potatoes in the culture soil. The culture soil contains the following components:

[0026] Coconut coir / peat soil: Its loose structure can improve compaction.

[0027] Perlite / vermiculite: Enhances porosity.

[0028] Biochar / decomposed wood chips: combines water retention and air permeability.

[0029] The disc 401 passes through the opening on the support frame 3 and extends to the bottom of the support frame 3. Multiple through holes 402 are provided around the disc 401 and at the bottom. A support ring 403 is fixedly connected to the outer surface of the disc 401 and above the support frame 3. The support ring 403 is used to restrict the downward movement of the disc 401, so that the disc 401 can completely pass through the support frame 3 and descend into the interior of the water replenishment tray 2.

[0030] like Figure 1The top of the seedling box 1 is equipped with a light-transmitting cover 5, and there is a light-emitting device outside the seedling box 1 to provide light during seedling cultivation. Breathable nets 6 are installed on both sides of the seedling box 1 to improve the air permeability inside the seedling box 1.

[0031] like Figure 2 and Figure 3 The top of the seedling box 1 is fixedly connected to a threaded shaft 7, and the bottom of the water replenishment tray 2 is provided with a support plate 8. The bottom of the support plate 8 is rotatably connected to a threaded sleeve 9. The threaded sleeve 9 and the threaded shaft 7 are threadedly connected, so that when the threaded sleeve 9 is rotated, the support plate 8 can be moved up and down, and the support plate 8 can drive the water replenishment tray 2 to move up and down.

[0032] like Figure 2 and Figure 3 The support plate 8 has a positioning slot 10. The bottom of the water replenishment tray 2 and inside the positioning slot 10 are fixedly connected to a support block 11, which can position the water replenishment tray 2 and align the water replenishment tray 2 under the seedling tray 4.

[0033] like Figure 2 and Figure 3 A guide rod 12 is fixedly connected to the bottom of the inner wall of the seedling box 1. A sliding block 13 is slidably connected to the guide rod 12. An inclined connecting rod 14 is rotatably connected to the top of the sliding block 13. The top of the inclined connecting rod 14 is rotatably connected to the bottom of the support plate 8. Two sets of guide rods 12, sliding blocks 13 and inclined connecting rods 14 are symmetrically arranged inside the seedling box 1. When the support plate 8 moves up and down, the sliding block 13 can be driven to slide on the guide rod 12 through the inclined connecting rod 14. The inclined connecting rod 14 plays the role of restricting the movement of the support plate 8 in the vertical direction.

[0034] like Figure 2 and Figure 3 Both sides of the inner wall of the seedling box 1 are equipped with supporting steel plates 15. The support frame 3 is provided with positioning holes 16. The top of the supporting steel plate 15 and inside the positioning hole 16 are fixedly connected to the positioning shaft 17. The supporting steel plate 15 provides support for the support frame 3. The positioning shaft 17 is inserted into the positioning hole 16 to prevent the support frame 3 from moving horizontally. The support frame 3 and the seedling tray 4 are positioned above the water replenishment tray 2.

[0035] The working principle of the sweet potato seedling raising device provided by this utility model is as follows:

[0036] When watering is needed for sweet potato seedlings, the threaded sleeve 9 can be manually rotated clockwise to move the support plate 8 and the watering tray 2 upward, so that the bottom of the seedling tray 4 is immersed in water. Water is then added to the sweet potato seedlings from the bottom of the seedling tray 4 until the surface of the potting soil inside the seedling tray 4 is slightly moist. Then, the threaded sleeve 9 can be manually rotated counterclockwise to move the watering tray 2 downward and separate it from the seedling tray 4, thus completing the watering of the sweet potato seedlings.

[0037] Lift the watering tray 2 directly to remove it from inside the seedling box 1 for easy water replacement. After seedling cultivation, place the support frame 3 directly on the platform, remove the support frame 3 and seedling tray 4 from inside the seedling box 1, and then remove the seedling tray 4 one by one to transplant the cultivated sweet potato seedlings.

[0038] Compared with related technologies, the sweet potato seedling raising equipment provided by this utility model has the following beneficial effects:

[0039] This invention involves cultivating sweet potato seedlings in a seedling tray 4 at a constant height. A water-filled tray 2 moves up and down to immerse the seedlings from the bottom, using capillary action to evenly moisten the substrate from bottom to top. This avoids direct watering that can lead to surface water accumulation, seed rot, and soil compaction. It keeps the surface of the potting soil loose and porous, making it easier for the seedlings to emerge, reducing the risk of "stunted growth," and promoting deeper root development, thus improving seedling vigor. It also maintains stable substrate moisture while reducing water on the leaves, thus preventing the spread of soil-borne diseases.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
