Description

Technical Field

[0001] This utility model relates to the field of germination box technology, and in particular to a germination box for soaking plant seeds. Background Technology

[0002] Plant soaking and germination boxes are key equipment in agricultural seedling cultivation, mainly used for the germination treatment of rice and other crop seeds after soaking. Their core function is to promote rapid and uniform seed germination by controlling the temperature, humidity, and oxygen environment.

[0003] Traditional germination boxes typically employ a single-layer structure, with seeds piled on perforated trays. Warm water or an electric heating device supplies heat to the bottom, and the lid has fixed vents for ventilation. While this type of equipment has been widely used for many years, it suffers from significant drawbacks. In practice, because the seed layer is often over 20 centimeters thick, residual moisture after soaking and water vapor from seed respiration easily form a water layer at the bottom. Prolonged submersion of the bottom seeds creates an oxygen-deficient environment, inducing anaerobic respiration and accompanied by ethanol accumulation, causing seeds to stick together, mold, and resulting in a rotten seed rate generally exceeding 10%. Furthermore, the insulation performance of existing equipment is insufficient to meet the requirements for continuous constant temperature, necessitating the replenishment of warm water five to eight times during a single germination cycle. Frequent opening and closing not only exacerbates heat loss but also causes drastic temperature fluctuations within the box, leading to severely uneven seed germination progress. These structural deficiencies in drainage and heat management have become key technical bottlenecks restricting the development of modern agriculture.

[0004] Therefore, this application provides a germination box for soaking plant seeds to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a germination box for soaking plant seeds, which solves the problems of existing germination boxes where water is difficult to drain after soaking, leading to oxygen deficiency and mold growth in the bottom seeds, and where the heat preservation time is too short, requiring frequent manual intervention to replenish the temperature.

[0006] To solve the above-mentioned technical problems, this utility model provides a germination box for soaking plant seeds, which includes an insulated box, a germination box nested inside the insulated box, and a box cover on the top of the germination box; The incubator has an annular sealing ring at the top edge and a horizontal overflow pipe installed on the side wall. The bottom of the box is a centrally raised first conical bottom, with the outer annular area of ​​the first conical bottom recessed downwards to form an annular water channel. The germination box has an inverted convex concentric cylindrical structure, with a small-diameter cavity at the bottom for seeds and a large-diameter cavity at the top for air. The bottom of the germination box has a second conical bottom that matches the first conical bottom. The diameter of the air cavity is equal to the inner diameter of the incubator. The outer edge of the bottom of the air cavity abuts against the sealing ring of the incubator to form a seal. The side wall of the air cavity and the side wall of the incubator form a continuous vertical sealing surface. An incubation cavity is formed between the outer wall of the seed cavity and the inner wall of the incubator. The sealing ring and the first conical bottom of the incubator together support the germination box to prevent horizontal displacement.

[0007] The further improvement of this utility model is that: the diameter of the seed chamber is 0.6-0.8 times the diameter of the air chamber; drainage holes are evenly opened on the bottom and side wall surface of the seed chamber, with a hole diameter of 2.5-3.0 mm and an opening rate of 40%-60%; the drainage holes penetrate through the seed chamber wall, so that the seed chamber and the heat preservation chamber are directly connected to form a three-dimensional drainage network.

[0008] A further improvement of this utility model is that: after the second conical bottom and the first conical bottom are nested together, a radial drainage channel with a consistent slope is formed at the bottom of the insulation box; the center of the bottom of the second conical bottom is a circular boss with a diameter equal to half the diameter of the seed cavity; drainage holes are distributed in the outer annular area of ​​the second conical bottom, and the width of the annular area is 1 / 4 to 1 / 2 of the diameter of the seed cavity; the first conical bottom and the second conical bottom boss are in contact and support each other.

[0009] A further improvement of this utility model is that two U-shaped handles are symmetrically installed on the outer edge of the top of the air chamber, with a 5cm gap reserved between the inner wall of the handle and the outer wall of the air chamber; the axis of the handle is parallel to the plane of the box cover, and the center of gravity passes vertically through the center of the seed chamber when it is lifted.

[0010] A further improvement of this utility model is that the radial thickness of the insulation cavity is 10-20cm, and the wall of the insulation box is made of a high thermal resistance composite material with a thermal resistance value ≥6.0m²K / W.

[0011] A further improvement of this utility model is that the inner opening of the overflow pipe is level with the lowest point of the seed chamber, and the overflow pipe extends through the side wall of the insulated box to the outside.

[0012] A further improvement of this utility model is that: the annular water channel is located directly below the annular area on the outer side of the first conical bottom, and its width is the same as the distribution area of ​​the drain hole, and its depth is 20-30cm; the warm water flowing out of the drain hole falls directly into the annular water channel, and continuously heats the insulation cavity through water heat radiation.

[0013] A further improvement of this utility model is that: an annular sealing gasket is provided on the lower surface of the box cover, and the box cover is divided into four 90° fan-shaped areas; an array of ventilation holes is opened in two staggered 90° areas, and a horizontally rotating cover plate is installed in the other two 90° areas.

[0014] A further improvement of this utility model is that the rotating cover controls the exposed area of ​​the ventilation holes by adjusting the angle. When rotated to 0°, it fully exposes two ventilation areas to achieve 100% ventilation. When rotated to 30°, it covers one ventilation area to achieve 50% ventilation. When rotated to 90°, it fully covers all ventilation areas to achieve sealing and heat preservation.

[0015] A further improvement of this utility model is that the vent holes are circular holes with a diameter of 5-8 mm, and are arranged in a concentric array within a 90° sector area, with the center distance between the holes being 2-3 times the diameter of the holes.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a germination box for plant seed soaking. The germination box has a double-layer structure formed by nesting an insulated box and a germination box together. A ring-shaped water channel is provided at the bottom of the insulated box to solve the problems of water accumulation and seed rot in traditional germination boxes, as well as heat loss. Drainage holes are opened on the entire surface of the seed chamber at the bottom of the germination box. Residual water after soaking can be quickly drained into the ring-shaped water channel of the insulated box, preventing oxygen deficiency during seed soaking. Simultaneously, the warm water stored in the ring-shaped water channel continuously heats the insulated chamber through thermal radiation, significantly extending the constant temperature time and reducing the frequency of artificial heating.

[0017] 2. This utility model provides a germination box for soaking plant seeds. The germination box achieves a balance between structural stability and efficient drainage through the coordinated support and drainage of a first conical bottom and a second conical bottom. The central boss of the second conical bottom is in close contact with the first conical bottom, forming a rigid support to prevent the germination box from shifting. Meanwhile, the drainage holes in the annular area outside the boss are aligned vertically with the annular waterway, allowing water to naturally flow along the conical surface into the overflow pipe for discharge, thus eliminating the risk of mold growth in the bottom seeds from the outset.

[0018] 3. This utility model provides a germination box for plant seed soaking. The germination box, through the cooperation of a four-zone ventilation hole on the lid and a rotating cover, precisely adapts to the gas requirements of each stage of seed germination. The staggered ventilation hole areas, combined with the rotating cover, allow for three levels of ventilation adjustment with just one hand: 100% ventilation by fully exposing the ventilation holes, 50% ventilation by covering one ventilation area, and sealing and heat preservation by completely covering all ventilation areas. This ensures sufficient sealing and heat preservation during the seed bud break stage, allowing for flexible switching between sufficient oxygen supply during the bud break stage and the heat preservation requirements during the mid-germination stage.

[0019] 4. This utility model provides a germination box for plant soaking, which overcomes the insulation bottleneck of traditional non-electrical equipment through an insulation cavity. The radial thickness of the insulation cavity is 10-20cm, and the box wall is made of high heat-resistant composite material, which effectively inhibits heat conduction; combined with the hydrothermal radiation effect of the annular water channel, it can maintain an effective constant temperature for more than four hours, significantly reducing production energy consumption.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further explained below with reference to specific embodiments.

[0027] like Figures 1-7 As shown, this embodiment provides a germination box for plant seed soaking, comprising an insulated box 1, a germination box 2 nested within the insulated box 1, and a lid 3 covering the top of the germination box 2. An annular sealing ring 13 is provided at the top edge of the insulated box 1, which tightly abuts against the outer edge of the bottom of the air cavity 22 of the germination box 2 to form an axial seal, effectively blocking heat loss channels. A horizontal overflow pipe 14 is installed on the side wall of the insulated box 1, its inner opening height precisely aligned with the lowest point of the bottom of the seed cavity 21. When the water level exceeds a safe threshold, it automatically drains, completely eliminating the risk of seed drowning. The overflow pipe 14 extends through the side wall of the insulated box 1 to the outside, forming the final drainage guarantee. The bottom of the insulated box 1 is designed as a centrally raised first conical bottom 11, with its outer annular area recessed downwards to form an annular water channel 12 with a depth of 20-3 cm. The width of this water channel perfectly matches the distribution area of ​​the drain holes 23 of the germination box 2, allowing the warm water discharged from the seed cavity 21 to accurately fall into the annular water channel 12 for storage.

[0028] like Figures 2-4As shown, in this embodiment, the germination box 2 adopts an inverted convex concentric cylindrical structure, with a small-diameter lower cavity as the seed cavity 21 and a large-diameter upper cavity as the air cavity 22. The diameter of the seed cavity 21 is designed to be 0.6-0.8 times the diameter of the air cavity 22, ensuring sufficient seed capacity while avoiding excessive accumulation. The bottom of the germination box 2 is provided with a second conical bottom 24, whose cone angle is 0.5°-1° larger than that of the first conical bottom 11, forming an interference fit. When the germination box 2 is nested inside the insulation box 1, the circular boss in the center of the second conical bottom 24 is in rigid contact with the apex of the first conical bottom 11. The diameter of this boss is half the diameter of the seed cavity 21, forming the main load-bearing structure; the outer edge of the bottom of the air cavity 22 is engaged with the sealing ring 13 of the insulation box 1, and together with the continuous vertical sealing surface formed by the side wall of the air cavity 22 and the side wall of the insulation box 1, a double anti-displacement locking is achieved. A heat-insulating cavity 25 with a radial thickness of 10-20cm is formed between the outer wall of the seed chamber 21 and the inner wall of the heat-insulating box 1. The wall of the heat-insulating box 1 is made of a high heat-resistant composite material with a thermal resistance value ≥6.0m²K / W, which significantly inhibits heat conduction.

[0029] like Figures 2-4 As shown, in this embodiment, drainage holes 23 with a diameter of 2.5-3.0 mm are uniformly opened on the bottom and sidewall surfaces of the seed cavity 21, with an opening rate of 40%-60%. These drainage holes 23 penetrate the cavity wall to form a three-dimensional drainage network, allowing direct communication between the seed cavity 21 and the heat preservation cavity 25. Drainage holes 23 are densely distributed in the outer annular area of ​​the second conical bottom 24. The width of this annular area is 1 / 4-1 / 2 of the diameter of the seed cavity 21, while the central boss area remains without holes, achieving separation of dry area support and wet area drainage. After soaking, the water flows into the annular waterway 12 through the drainage holes 23 within three minutes, which is five times more efficient than traditional drainage, eliminating the risk of mold growth in the bottom seeds. The warm water stored in the annular waterway 12 continuously heats the heat preservation cavity 25 through thermal radiation, making the heat energy utilization rate of the irrigation water reach more than 80%, and extending the constant temperature maintenance time to four hours.

[0030] like Figures 2-4 As shown, in this embodiment, two U-shaped handles 26 are symmetrically installed along the outer edge of the top of the air chamber 22. A 5cm gap is reserved between the inner wall of the handle 26 and the outer wall of the air chamber 22 to effectively prevent condensate from contacting and corroding the seeds. The axis of the handle 26 is parallel to the plane of the cover 3, and when lifted, the center of gravity passes vertically through the center of the seed chamber 21, ensuring stable and effortless operation by a single person. An annular sealing gasket is provided on the lower surface of the cover 3, and the cover is divided into four 90° fan-shaped areas: two of the staggered areas have arrayed ventilation holes 31 with a diameter of 5-8mm, arranged in concentric circles with a center-to-center distance of 2-3 times the diameter of the holes, to achieve uniform airflow diffusion; the other two areas are equipped with horizontally rotating cover plates 32. When rotated at 0°, the dual ventilation area 31 is fully exposed to achieve 100% ventilation; when rotated at 30°, the single ventilation area 31 is covered to achieve 50% ventilation; and when rotated at 90°, it is completely sealed. This mechanical air regulation structure precisely matches the high oxygen consumption during the seed bud break stage and the heat preservation requirements during the mid-germination stage.

[0031] This utility model also provides a working principle for a germination box used for soaking plant seeds: After soaking, the seeds are poured into the seed chamber 21 of the germination box 2. Warm water of appropriate temperature is poured into the air chamber 22 according to the seed variety. The warm water is quickly drained from the drainage holes 23 at the bottom and side walls of the seed chamber 21 into the annular water channel 12 of the first conical bottom 11 of the heat preservation box 1. The cover plate 32 of the box cover 3 is rotated to the 0° position to fully expose the ventilation hole 31, which promotes oxygen supply during the seed bud break stage. The poured warm water flows into the annular water channel 12 through the drainage hole 23 and is stored, continuously supplying heat to the heat preservation chamber 25 through hydrothermal radiation. After the seeds bud break and even germinate, the cover plate 32 is rotated to 90° to seal and keep the temperature constant for 4 hours. After germination, the handles 26 on both sides of the air chamber 22 are held vertically and pulled up. The second conical bottom 24 is separated from the first conical bottom 11. The overflow pipe 14 is always flush with the bottom of the seed chamber 21 to prevent water accumulation and seed flooding.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
