Description

Technical Field

[0001] This utility model belongs to the field of seedling equipment technology, and in particular relates to a seed germination device for forestry seedling cultivation. Background Technology

[0002] In forestry seedling cultivation, seed germination is a key step in improving germination rate and shortening the seedling cycle. Seed soaking is a commonly used physical germination method. By controlling water temperature, soaking time and dissolved oxygen, seed dormancy can be effectively broken and embryo germination can be promoted. Repeated soaking and air-drying of seeds can achieve the effect of seed germination. However, when germinating large quantities of seeds, it is necessary to constantly take the seeds out of the soaking solution and put them back in, which increases the workload of staff and is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a seed germination device for forestry seedling cultivation, which can conveniently perform intermittent soaking of seeds.

[0004] The aforementioned forestry seed germination equipment includes a U-shaped fixed frame with several soaking components for soaking groups of seeds. Each soaking component includes a soaking basket for holding soaking solution, a support plate above the soaking basket, and several limiting holes on the support plate. Each limiting hole contains a seedling tray for placing seeds. The left and right inner side walls of the fixed frame have grooves. A threaded rod is rotatably connected in one groove, with the top end of the threaded rod passing through the fixed frame and connecting to a motor. A sliding rod is fixed in the other groove. Adjustment plates are fixed on the support plate. One adjustment plate has a threaded hole that is threaded to the threaded rod, and the other adjustment plate has a fixed hole that is slidably engaged with the sliding rod.

[0005] Furthermore, two movable slots are provided on both sides of the fixed frame, which are arranged in a front-to-back manner. Each movable slot is provided with a movable plate fixed on the soaking basket. After the movable plate extends out of the movable slot, it is connected to the connecting plate. The two connecting plates are connected by a fixed plate. The fixed plate is provided with several threaded holes, and screws are threaded into each threaded hole. The tightening end of the screw abuts against the side wall of the fixed frame.

[0006] Furthermore, two symmetrically distributed sliding grooves are provided in the groove, and each sliding groove is provided with a slider fixed to the adjusting plate.

[0007] Furthermore, the bottom edge of the seedling pot is provided with several evenly distributed insertion rods, and several insertion holes are provided on the top of the support plate corresponding to the insertion rods for mutual insertion.

[0008] Furthermore, the seedling pot is cut into two parts, left and right, along the vertical direction, and the bottom of the two parts are hinged together.

[0009] Furthermore, the movable plate, connecting plate, and fixed plate are integrally formed structures.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention uses a motor to drive the output shaft of a threaded rod to rotate. Under the action of two adjusting plates, several seedling trays on the support plate are moved to soak the seeds in the seedling trays. After soaking, the support plate is driven to move upward, so that the seeds in the seedling trays are removed from the soaking solution. This allows for convenient intermittent soaking of seeds, improves seed germination rate, reduces the workload of staff, and saves time and effort. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0018] This embodiment describes a forestry seed germination device, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a U-shaped frame 1, on which several soaking components for soaking groups of seeds are installed. The soaking components include a soaking basket 3 for holding soaking solution, a support plate 6 above the soaking basket 3, and several limiting holes on the support plate 6. Seedling pots 7 for placing seeds are installed in each limiting hole. Grooves are provided on the left and right inner side walls of the frame 1. A threaded rod 8 is rotatably connected in one of the grooves. The top of the threaded rod 8 passes through the frame 1 and is connected to a motor 9. A sliding rod 2 is fixed in the other groove. Adjusting plates 5 are fixed on the support plate 6. One adjusting plate 5 has a threaded hole that is threaded to the threaded rod 8, and the other adjusting plate 5 has a fixed hole that is slidably engaged with the sliding rod 2.

[0019] The two side walls of the fixing frame 1 are arranged left and right. Several sets of soaking components are installed on the fixing frame 1. Each set of soaking components includes a soaking basket 3, into which soaking solution is poured. A support plate 6 is installed above each soaking basket 3. Several limiting holes on the support plate 6 are used to embed seedling trays 7, which hold seeds. Several liquid inlet holes are provided on the bottom and side walls of the seedling trays 7. When the seedling trays 7 are placed in the soaking basket 3, the soaking solution enters the seedling trays 7 through the liquid inlet holes to soak the seeds. The diameter of the liquid inlet holes is smaller than the diameter of the seeds to avoid... Seeds leak from the liquid inlet, and soaking softens the seed coat, enhances oxygen permeability, accelerates seed water absorption and swelling, and activates intracellular enzyme systems, thereby breaking dormancy. After absorbing water, the seeds' metabolic activity increases, and the heat released by respiration further raises the temperature of the seed pile, forming a virtuous cycle. Sufficient water absorption allows the seeds to reach the moisture content required for germination, significantly shortening germination time. Empty shells and shriveled seeds floating on the water surface after soaking can be removed, leaving healthy seeds at the bottom, improving seedling efficiency. Seedlings germinated from soaked seeds have more developed root systems, stronger resistance, and more vigorous growth.

[0020] The inner walls of both the left and right sidewalls of the fixing frame 1 are provided with grooves. A threaded rod 8 is rotatably connected to the groove on the left side via a bearing. A through hole is provided at the top of the groove. A motor 9 is installed at the top of the left sidewall of the fixing frame 1, and the output shaft of the motor 9 extends into the through hole and connects to the top of the threaded rod 8. A sliding rod 2 is welded or glued into the groove on the right side. Adjusting plates 5 are welded or glued to the left and right sidewalls of the support plate 6. The adjusting plates 5 have an "L" shape. A threaded hole is provided on the left adjusting plate 5, and the threaded rod 8 passes through the threaded hole and is threadedly engaged with it. The sliding rod 2 passes through the fixing hole on the right adjusting plate 5 and slides up and down with it. In use, the motor 9 is started, causing its output shaft to drive the threaded rod 8 to rotate in the groove. The threaded rod 8 engages with the threaded hole of the adjusting plate 5, thereby driving the adjusting plate 5 to move up and down on the threaded rod 8, which in turn drives the other adjusting plate 5 to move up and down on the sliding rod 2, causing the support plate 6 to move down. The seedling pot 7 is then immersed in the soaking solution in the soaking basket 3. After sufficient soaking time... The motor 9 is driven to rotate in the opposite direction, causing the threaded rod 8 to rotate. This drives the adjusting plate 5 to move the support plate 6 and several seedling pots 7 upwards, removing them from the soaking solution. This causes the seeds on several sets of soaking components to be repeatedly soaked. The alternating wet and dry conditions stimulate seed respiration and metabolism, improving oxygen exchange efficiency and avoiding the risk of rotting due to lack of oxygen caused by prolonged soaking. Each repeated soaking increases the seed moisture content, and the intermittent soaking causes the seed coat to undergo a physical cycle of "water absorption and contraction," increasing the seed coat cracking rate of hard-shelled seeds and accelerating radicle breakthrough. Furthermore, different agents can be used for each repeated soaking, which can eliminate surface pathogens and insect eggs. The soaking solution can penetrate the seed coat to form an internal protective layer. By repeatedly flotating, defective seeds exposed at different developmental stages are removed, such as empty shells in the first flotation and moldy seeds in the second, resulting in a higher germination rate for the remaining seeds. At the same time, controlling the repeated soaking of a large number of seeds enables standardized operation, avoiding the tedious manual retrieval and placement of seeds. This method is suitable for large-scale seedling cultivation, improving seed soaking efficiency and saving time and labor.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, two movable slots 12 are provided on both side walls of the fixed frame 1, arranged in a front-to-back pattern. Movable plates 16, fixed to the soaking basket 3, are installed in each movable slot 12. The movable plates 16 extend out of the movable slots 12 and connect to connecting plates 4. The two connecting plates 4 are connected by a fixed plate 13. The fixed plate 13 has several threaded holes, each threaded with a screw 14. The tightening end of the screw 14 presses against the side wall of the fixed frame 1. Two movable plates 16 are provided on both the left and right sides of the soaking basket 3. Corresponding to the four movable plates 16, movable slots 12 are provided on the left and right side walls of the fixed frame 1. The two movable plates 16 on the left and right sides extend out of the movable slots 12 and connect to connecting plates 4. The front side walls of the two connecting plates 4 are connected to a fixed plate 13. The fixed plate 13 has two threaded holes, each threaded with a screw 14. Furthermore, the movable plates 16, connecting plates 4, and fixed plates 13 are integrally formed, facilitating manufacturing. The connection with the fixing plate 13 is more secure. When in use, pour the soaking solution into the soaking basket 3. When it is necessary to move the basket to soak one or more groups of seeds individually, loosen the screw 14 to release the binding of the fixing plate 13. Move the fixing plate 13 to move the two connecting plates 4. The two connecting plates 4 move the moving plate 16 up and down in the moving groove 12, which in turn moves the soaking basket 3 up and down. The soaking basket 3 moves up to below the seedling tray 7 so that the seeds in the seedling tray 7 are soaked in the soaking solution in the soaking basket 3. Then tighten the screw 14 so that the top end is pressed against the side wall of the fixing frame 1 to fix the position of the soaking basket 3. The soaking time or temperature can be adjusted for seeds with different seed coat thickness and dormancy levels. Soaking parameters such as time and water temperature can be adjusted for seeds of the same variety but in different states to avoid insufficient or excessive water absorption in the same batch of seeds. Soak seeds with inconsistent maturity in groups to ensure synchronous water absorption, so that the growth rate of the same batch of seeds is uniform and the germination efficiency is improved.

[0022] like Figure 2 and Figure 4 As shown, two symmetrically distributed sliding grooves are provided in the groove, and each sliding groove is equipped with a slider 10 fixed on the adjusting plate 5. Slider 10s distributed front and back are welded or glued to the two adjusting plates 5 on the left and right side walls of the support plate 6. With the slider 10 sliding in the sliding groove, the two adjusting plates 5 move up and down more smoothly, further improving the smoothness of the movement of the support plate 6 and avoiding violent shaking that could damage the embryo or seed coat. The smooth movement of the support plate 6 can maintain the integrity of the seed. The smooth movement of the seed into the soaking solution allows the soaking solution to come into full contact with the seed, improving its germination efficiency.

[0023] like Figure 2 and Figure 4As shown, the bottom edge of the seedling pot 7 is provided with several evenly distributed insertion rods 11, and several insertion holes 15 are opened on the top of the support plate 6 corresponding to the insertion rods 11, which are inserted into each other; several insertion rods 11 are welded or glued to the bottom edge of the seedling pot 7, and the insertion rods 11 are inserted into each other with several insertion holes 15 at the upper limit hole, fixing the seedling pot 7 on the support plate 6, further ensuring the stability during seed soaking or movement.

[0024] The seedling tray 7 is cut vertically into two parts, left and right, and the bottom of the two parts are hinged together (not shown in the figure). After the seeds are soaked, the seedling tray 7 is taken out from the limiting hole. The left and right parts of the seedling tray 7 are rotated to better retrieve the seeds stored in the seedling tray 7, so as to avoid the seeds sticking to the inner wall of the seedling tray 7 and being difficult to remove. Forcibly removing the seeds may damage the seed embryo and affect its germination efficiency.

[0025] In practical use, seeds are placed into several seedling trays 7 in several sets of soaking components, and soaking solution is poured into the soaking baskets 3 in several sets of soaking components. The motor 9 is started so that its output shaft drives the threaded rod 8 to rotate. The threaded hole on one of the adjustment plates 5 is threadedly engaged with the threaded rod 8, which drives the adjustment plate 5 to move down, thereby driving another adjustment plate 5 to slide up and down on the slide rod 2, driving several seedling trays 7 on the support plate 6 to move. The seedling trays 7 enter the soaking baskets 3. After soaking, the support plate 6 is driven to move up, so that the seeds in the seedling trays 7 are removed from the soaking solution. Repeated soaking of seeds can improve the seed germination rate and reduce the workload of staff, which is more time-saving and labor-saving.
