Description

Technical Field

[0001] This utility model relates to the field of watermelon seedling cultivation technology, specifically a watermelon seed soaking device. Background Technology

[0002] Watermelon seeds have a hard seed coat with a waxy layer, and direct sowing can lead to uneven water absorption, affecting germination speed. Soaking allows the seed coat to absorb water, swell, and soften, making it easier for the radicle to break through the seed coat. Soaking also accelerates the activity of enzymes inside the seed, breaking down stored nutrients and providing energy for germination. For example, soaking in 55℃ warm water can sterilize and stimulate embryo awakening, while cell membrane permeability is optimal when the water temperature is maintained at 25-30℃. Proper soaking can increase the germination rate by 20%-30% and shorten the germination time (from 5-7 days to 2-3 days).

[0003] Watermelon seed germination requires extensive soaking of the seeds. The conventional soaking method is as follows: place the watermelon seeds in a container, pour in warm water and soak for 6-8 hours, then place the seeds on a damp gauze and wait for germination. Currently, there are two sources of watermelon seeds: those purchased from the market and those cultivated at home. The former contains chemicals on the surface of the seeds, which will cause the water to contain these chemicals after soaking. The latter leaves the seeds with a slippery surface after soaking. Neither method is convenient for spreading the seeds evenly by hand. Therefore, a soaking device that can spread the seeds evenly is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a watermelon seed soaking device that has the advantage of evenly spreading the soaked seeds, thus solving the aforementioned problems.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of evenly spreading soaked seeds, this utility model provides the following technical solution: a watermelon seed soaking device, comprising an outer shell, a drain pipe fixedly installed at the bottom of the outer shell, a drain valve fixedly installed at the other end of the drain pipe, an inner shell inserted inside the outer shell, a limiting strip fixedly installed on the inner wall of the inner shell, a mesh plate slidably installed inside the inner shell via the limiting strip, two symmetrically arranged handles fixedly installed on the top of the mesh plate, a central ring embedded in the center of the top of the mesh plate, a shaft inserted inside the central ring, scrapers fixedly installed on both sides of the bottom of the shaft, a horizontal plate fixedly installed on the top of the shaft, and a rotating handle rotatably installed on one end surface of the horizontal plate.

[0008] Preferably, the inner wall of the central ring is provided with an installation groove, a spring is fixedly installed inside the installation groove, a T-shaped clamp is fixedly installed on one side of the spring, and an annular grooves with equal spacing are provided on the outer side of the shaft.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a watermelon seed soaking device, which has the following beneficial effects:

[0014] 1. This watermelon seed soaking device involves placing the seeds in the inner shell, then using the handle to cover the inner shell with a mesh plate on its stepped surface. The inner shell is then positioned on the inner stepped surface of the outer shell through the hand-holding holes. Water from the outer shell rises from the bottom holes of the inner shell, while the mesh plate ensures all seeds are submerged. A rotating handle drives a horizontal plate, which in turn rotates the shaft within the central ring. The inclined scraper at the bottom of the shaft evenly spreads the seeds, eliminating the need for manual spreading and solving the problems of seeds containing chemicals or slippery seeds requiring manual spreading during soaking.

[0015] 2. This watermelon seed soaking equipment, by applying force to the horizontal plate to pull it up or press it down, the shaft can squeeze the T-shaped clamp head through the annular groove. In this way, the T-shaped clamp head and the annular groove slide out of place, which can realize the upward or downward movement of the shaft, thereby controlling the distance between the scraper and the bottom wall of the inner shell, and thus controlling the thickness of the seed spreading.

[0022] 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.

[0023] Please see Figure 1-3 A watermelon seed soaking device includes an outer shell 1, the inner bottom wall of which is gradually inclined from the outside to the inside to facilitate the flow of water towards the center; a drain pipe 2 is fixedly installed at the bottom of the outer shell 1, and a drain valve 3 is fixedly installed at the other end of the drain pipe 2, so that the water in the outer shell 1 can be discharged by opening the drain valve 3; an inner shell 4 is inserted inside the outer shell 1, and the inner wall of the outer shell 1 and the outer and inner walls of the inner shell 4 are provided with stepped steps; the inner bottom wall of the inner shell 4 is provided with eye holes, and the outer wall of the inner shell 4 is provided with hand grip holes 17; the outer shell 1, the inner shell 4 and the mesh plate 6 are all made of transparent plastic to facilitate the observation of the seeds.

[0024] Please see Figure 1-3 A limiting strip 5 is fixedly installed on the inner wall of the inner shell 4. A mesh plate 6 is slidably installed inside the inner shell 4 through the limiting strip 5. Two symmetrically arranged handles 7 are fixedly installed on the top of the mesh plate 6. A limiting notch corresponding to the limiting strip 5 is opened on the outer side of the mesh plate 6. The mesh plate 6 is slidably installed on the stepped steps of the inner wall of the inner shell 4 through the limiting strip 5 and the limiting notch, so as to ensure that the mesh plate 6 can only slide up and down and cannot rotate on its own.

[0025] Please see Figure 4-5A central ring 8 is embedded in the top center of the mesh plate 6. A shaft 9 is inserted and installed inside the central ring 8. Scrapers 10 are fixedly installed on both sides of the bottom of the shaft 9. There are two scrapers 10, which are symmetrically arranged and inclined, and flush with the bottom of the shaft 9. A horizontal plate 15 is fixedly installed on the top of the shaft 9. A handle 16 is rotatably installed on one end of the horizontal plate 15. The handle 16 can drive the horizontal plate 15, the shaft 9, and the scrapers 10 to rotate, and the scrapers 10 can spread and flatten the seeds.

[0026] Please see Figure 4-5 The inner wall of the central ring 8 has an installation groove 11, and a spring 12 is fixedly installed inside the installation groove 11. A T-shaped clamp 13 is fixedly installed on one side of the spring 12. The outer side of the shaft 9 has annular grooves 14 arranged at equal intervals. The shaft 9 is movably engaged with the central ring 8 through the spring 12, the T-shaped clamp 13, and the annular grooves 14. By driving the shaft 9 to move up or down in the central ring 8, the distance between the scraper 10 and the bottom wall of the inner shell 4 can be controlled, thereby controlling the thickness of the seed spreading.

[0027] Working principle: When in use, place the seeds in the inner shell 4, and then cover the inner shell 4 with the mesh plate 6 through the handle 7. Place the inner shell 4 on the inner step of the outer shell 1 through the hand grip hole 17. In this way, the water in the outer shell 1 rises and emerges from the hole at the bottom of the inner shell 4, and the mesh plate 6 ensures that the seeds are submerged in the water.

[0028] The horizontal plate 15 can be driven to rotate by the handle 16. The horizontal plate 15 rotates with the shaft 9 in the central ring 8. The inclined scraper 10 at the bottom of the shaft 9 can spread the seeds evenly, ensuring that the user does not need to spread the seeds by hand. This solves the problem of seeds containing pesticides or seeds that are slippery after soaking in water and need to be spread by hand in traditional methods.

[0029] By applying force to the horizontal plate 15 to pull it up or press it down, the shaft 9 can squeeze the T-shaped clamp 13 through the annular groove 14. In this way, the T-shaped clamp 13 and the annular groove 14 slide out of alignment, which can realize the upward or downward movement of the shaft 9, thereby controlling the distance between the scraper 10 and the bottom wall of the inner shell 4, and thus controlling the thickness of the seed spreading.

[0030] After the shaft 9 slides up and down, the spring 12 will push the T-shaped clamp 13 into the annular groove 14, which can restrict the position of the shaft 9 without affecting its rotation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
