Description

Technical Field

[0001] This utility model relates to the field of agricultural germination technology, and more specifically, to an agricultural planting germination device. Background Technology

[0002] In the field of modern agricultural planting technology, the seed germination process is the starting stage of crop growth, and its treatment effect directly affects the germination rate, growth rate and final yield of subsequent crops. However, although germination technology plays a crucial role in agricultural production, the agricultural planting germination devices widely used in the market still have many technical defects that urgently need to be solved.

[0003] Firstly, from the perspective of the seed contact environment, in traditional germination devices, due to the large number and small size of seeds, they easily accumulate and form dense clusters during water immersion. This non-ideal accumulation state leads to a series of deep-seated technical problems: seeds inside the accumulation are tightly surrounded by other seeds, making it difficult for external oxygen to penetrate to the inner area, resulting in a relatively oxygen-deficient environment; at the same time, seeds in the center of the accumulation cannot fully contact the external water, leading to severely uneven water absorption among the seeds. This uneven treatment environment directly results in significant differences in germination speed among seeds in the same batch, seriously affecting the overall uniformity and production efficiency of the germination batch. It also increases the technical difficulty and labor costs of subsequent planting stages. This situation is particularly prominent in large-scale commercial agricultural production. Uneven germination not only prolongs the overall germination cycle but may also increase the risk of seed rot, ultimately leading to waste of planting resources and a decline in economic benefits.

[0004] Secondly, regarding the technological deficiencies in the oxygen supply system, while some improved germination devices recognize the importance of oxygen for seed germination and utilize oxygen delivery jets at the bottom of the pool to generate numerous tiny bubbles in the water to ensure sufficient contact between seeds and oxygen, and the water flow disturbance generated by the rising bubbles helps to break up seed clumps and improve the uniformity of seed water absorption, these devices still have serious technical flaws: the oxygen delivery system uses a simple constant-speed pump, making the oxygen delivery speed a fixed, unadjustable value. This results in the intensity and density of bubble generation in the water remaining constant. This rigid design completely ignores the different types of seeds (such as soybeans and corn). Significant differences exist in the volume, shape, and epidermal characteristics of seeds (such as wheat), and these differences affect the different requirements for bubble intensity. For example, seeds with hard, smooth surfaces require strong bubble impact to effectively break up the pile and keep them suspended; while small, lightweight seeds may be washed to the surface by excessive bubble impact, resulting in some seeds not being fully soaked. The fixed oxygen delivery rate cannot be dynamically adjusted according to these changes, causing the bubble jet intensity to remain constant. Either it is too strong, causing energy waste and excessive seed distribution, or it is too weak, failing to effectively solve the seed accumulation problem. In both cases, the best germination effect cannot be achieved, seriously affecting the efficiency of agricultural production and resource utilization.

[0005] Furthermore, from the perspective of equipment reliability, while a few technologies on the market do indeed achieve flexible adjustment of oxygen delivery speed, these devices still face severe stability challenges in practical applications. The adjustment mechanism typically employs a simple mechanical structure, making the system highly susceptible to various interference factors during gas delivery, such as pressure pulsations within the pipeline and vibration transmission from the air pump. This causes the carefully adjusted flow control components to gradually experience small but cumulative displacements over long periods of operation. In actual agricultural production environments, germination equipment often needs to run continuously for hours or even days, making the cumulative effect of these small displacements even more significant. Ultimately, these minute displacements cause the adjusted oxygen delivery speed to drift continuously, resulting in constant changes in the distribution and intensity of air bubbles in the water. This severely affects the stability and controllability of the germination process. In actual production, this problem can lead to uneven growth and significant differences in germination rates within the same batch of seeds, not only reducing the overall seed quality but also increasing the labor intensity and management difficulty of subsequent planting stages, ultimately causing a significant negative impact on agricultural production efficiency and economic benefits. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides an agricultural planting germination device to solve the technical problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an agricultural planting germination device, comprising a water tank, a germination device installed inside the water tank, and a speed regulating device installed outside the water tank. The speed regulating device includes an input pipe, a distribution pipe, an adjusting sleeve, an adjusting plate, an adjusting shaft, an adjusting groove, and a movable shaft. One end of the distribution pipe extends into the inside of the water tank. Both ends of the adjusting sleeve are rotatably connected to the input pipe and the distribution pipe, respectively. The input end of the input pipe is connected to an external air supply device. The adjusting shaft and the movable shaft are rotatably mounted on the adjusting plate, and one end of the movable shaft rotates with the distribution pipe. The connection is as follows: one end of the adjusting shaft slides in the adjusting groove, which is located on one side of the input pipe; a locking mechanism is installed on the outside of the distribution pipe; the locking mechanism includes a locking sleeve, a movable plate, a movable hole, a movable rod, a locking block, a locking spring, and a locking block; the locking sleeve is slidably installed on the outside of the distribution pipe; the movable plate is rotatably installed on the outside of the distribution pipe; the movable hole is located on the movable plate; the movable rod is fixedly connected to one side of the locking sleeve; multiple locking blocks are movably arranged on one side of the adjusting sleeve; the two ends of the locking spring are respectively connected to two adjacent locking blocks; and multiple locking blocks are fixedly installed on the outside of the distribution pipe.

[0010] The present invention is further configured such that the germination device includes a storage chamber, through holes, a water inlet pipe, a water outlet, and nozzles. The storage chamber is detachably placed inside the water tank. Multiple through holes are formed on the side wall and bottom of the storage chamber. The water inlet pipe is fixedly connected to both sides of the top of the water tank. The water outlet is formed at the bottom of the water tank. An external valve is connected to the outside of the water outlet. Multiple nozzles are fixedly installed on the top of the distribution pipe. This structural design allows the seeds in the storage chamber to fully contact water and air bubbles, avoiding seed accumulation and ensuring uniformity of water absorption and oxygen contact. At the same time, the multiple through hole design facilitates water and air bubbles to enter the storage chamber from multiple directions, forming an all-round impact, further improving the uniformity and efficiency of germination.

[0011] The present invention is further provided that a handle is fixedly connected to the top of the storage chamber. The handle design makes it easy for operators to take out the storage chamber, which simplifies the collection of germinated seeds and the process of putting in new seeds, and improves the convenience of operation and work efficiency.

[0012] The present invention is further configured such that a movable spring is connected to one side of the locking sleeve, the movable spring is sleeved on the outside of the movable rod, and the other end of the movable spring is in contact with the movable plate. The movable spring provides a reliable automatic reset function for the locking sleeve, and at the same time, the elastic force of the movable spring provides a preload force for the locking sleeve.

[0013] The present invention is further configured such that a locking groove is provided in the locking block, and a plurality of locking rails are connected to one side of the adjusting sleeve. The locking groove is adapted to the locking rails, and the sliding cooperation between the locking groove and the locking rails ensures that the locking block maintains a stable movement trajectory during movement.

[0014] The present invention is further configured such that the adjustment plate has multiple adjustment holes.

[0015] The present invention is further configured such that a locking wheel is rotatably provided on one side of the locking block, and the locking wheel is engaged between the two locking blocks. The design of the locking wheel reduces the frictional resistance during the locking process, and the point contact engagement between the locking wheel and the locking block can form a reliable self-locking effect.

[0016] The present invention is further provided with multiple anti-slip strips on the outer sides of the adjusting sleeve, locking sleeve and movable plate. The anti-slip strips enhance the operator's control over each component, prevent slippage during adjustment, and improve the accuracy and safety of operation.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an agricultural planting germination device, which has the following features:

[0019] Beneficial effects:

[0020] 1. The germination device solves a series of deep-seated technical problems caused by the easy accumulation of seeds during water immersion in existing technologies by setting up a detachable storage chamber in the water tank and designing multiple through holes on the side wall and bottom of the storage chamber. The multiple through holes on the side wall and bottom ensure that water can penetrate into the storage chamber from multiple directions and angles, so that each seed can fully contact the water. In particular, when the nozzle at the top of the distribution pipe sprays out fine air bubbles, these air bubbles enter the storage chamber through the through holes, creating a comprehensive micro-impact on the seeds, effectively preventing the seeds from piling up and allowing the seeds inside to concentrate. This structural design, which ensures ample contact with oxygen while guaranteeing uniform water absorption by the seeds, greatly improves the seed germination environment, making the germination speed of seeds in the same batch more consistent. This significantly improves the overall uniformity and production efficiency of the germination batch. In addition, the handle design at the top of the storage chamber allows operators to easily remove the storage chamber from the water tank, facilitating the collection of germinated seeds and the addition of a new batch of seeds. This scientific and reasonable germination environment control system effectively shortens the overall germination cycle, reduces the risk of seed rot, avoids the waste of planting resources, and improves the economic benefits of agricultural production.

[0021] 2. The speed control device employs an innovative combination of an input pipe, distribution pipe, adjusting sleeve, adjusting plate, adjusting shaft, adjusting groove, and movable shaft. This fundamentally solves the technical shortcomings of existing oxygen supply systems. Unlike traditional devices that use simple constant-speed pumps resulting in a fixed oxygen delivery speed, this device achieves precise control of the internal flow area of ​​the pipeline through the rotational connection of the adjusting sleeve with the input and distribution pipes, and the sliding engagement of the adjusting shaft in the adjusting groove. This allows for precise control of the oxygen delivery speed. This flexible speed control design completely overcomes the limitations of rigid design concepts in existing technologies, enabling adjustments based on different seed types (such as soybeans, corn, and wheat). Based on differences in size, shape, and surface characteristics, the system dynamically adjusts the intensity of bubble jets. For example, for seeds with hard, smooth surfaces, the flow area can be increased to improve oxygen delivery speed and generate a stronger bubble impact force, effectively breaking up seed accumulation and keeping them suspended. For small, lightweight seeds, the flow area can be reduced to decrease oxygen delivery speed, avoiding the problem of seeds being washed to the water surface and not being fully soaked due to excessive bubble impact. This adjustable oxygen supply system can be adjusted according to different seed characteristics and germination stage requirements to ensure optimal germination results, significantly improving agricultural production efficiency and resource utilization.

[0022] 3. The locking mechanism is precisely assembled from components such as the locking sleeve, movable plate, movable hole, movable rod, locking block, locking spring, and locking block. This effectively solves the problem of insufficient reliability in existing technologies. Compared to devices on the market that rely solely on simple mechanical structures for speed adjustment but face stability challenges, this mechanism incorporates multiple safety mechanisms to ensure stable oxygen delivery speeds during long-term operation. First, the engagement design between the locking wheel and the locking block forms the first layer of locking. Second, the inner wall of the locking sleeve limits the outer wall of the locking wheel, providing the second layer of protection. Third, the rotating mechanism of the movable rod and the movable hole provides the third layer of safety. Finally, the sliding engagement of the locking block on the locking rail via the locking groove provides the fourth layer of protection. This multi-stage locking structure effectively resists various interference factors during gas delivery, such as pressure pulsations in the pipeline and vibration transmission from the air pump, preventing damage even after adjustment. When the adjustment system becomes loose or displaced, especially when the movable plate rotates to a position where the movable hole and movable rod do not align, the movable rod supports the locking sleeve, and the inner wall of the locking sleeve limits the outer wall of the locking wheel, putting the entire system into a fully locked state and ensuring that the adjustment sleeve cannot rotate at all. In addition, multiple anti-slip strips on the outer sides of the adjustment sleeve, locking sleeve, and movable plate enhance the operator's control over the components and prevent slippage during adjustment. In actual agricultural production applications, this highly stable locking mechanism can prevent the cumulative effect of small displacements, even if the equipment needs to run continuously for several hours or even days. This ensures that the adjusted oxygen delivery speed remains stable and that the distribution and intensity of air bubbles in the water do not change, thereby guaranteeing the stability and controllability of the germination process, improving the overall seed quality, and ultimately providing a solid guarantee for agricultural production efficiency and economic benefits.

[0032] Please see Figures 1-5 An agricultural germination device includes a water tank 1, with a germination device installed inside the water tank 1 and a speed regulating device installed outside the water tank 1. The speed regulating device includes an input pipe 2, a distribution pipe 3, an adjusting sleeve 4, an adjusting plate 5, an adjusting shaft 6, an adjusting groove 7, and a movable shaft 8. One end of the distribution pipe 3 extends into the inside of the water tank 1. Both ends of the adjusting sleeve 4 are rotatably connected to the input pipe 2 and the distribution pipe 3, respectively. The input end of the input pipe 2 is connected to an external air supply device. The adjusting shaft 6 and the movable shaft 8 are rotatably mounted on the adjusting plate 5. One end of the movable shaft 8 is rotatably connected to the distribution pipe 3, and one end of the adjusting shaft 6 slides in the adjusting groove 7. In the middle, the adjusting groove 7 is opened on one side of the input pipe 2, and a locking mechanism is installed on the outside of the distribution pipe 3. The locking mechanism includes a locking sleeve 9, a movable plate 10, a movable hole 11, a movable rod 12, a locking block 13, a locking spring 14, and a locking block 15. The locking sleeve 9 is slidably installed on the outside of the distribution pipe 3, the movable plate 10 is rotatably installed on the outside of the distribution pipe 3, the movable hole 11 is opened on the movable plate 10, the movable rod 12 is fixedly connected to one side of the locking sleeve 9, multiple locking blocks 13 are movably arranged on one side of the adjusting sleeve 4, the two ends of the locking spring 14 are respectively connected to two adjacent locking blocks 13, and multiple locking blocks 15 are fixedly installed on the outside of the distribution pipe 3.

[0033] The germination device includes a storage chamber 16, through holes 17, an inlet pipe 18, an outlet 19, and nozzles 20. The storage chamber 16 is detachably placed inside the water tank 1. Multiple through holes 17 are opened on the side wall and bottom of the storage chamber 16. The inlet pipe 18 is fixedly connected to both sides of the top of the water tank 1. The outlet 19 is opened at the bottom of the water tank 1. An external valve is connected to the outside of the outlet 19. Multiple nozzles 20 are fixedly installed on the top of the distribution pipe 3.

[0034] The top of the storage compartment 16 is fixedly connected to a handle 22.

[0035] In this embodiment, when the device is needed, first ensure that the valve connected to the outlet 19 is closed. Then, place the seeds into the storage chamber 16. Next, open the water supply device connected to the inlet pipe 18 to deliver clean water into the pool 1, gradually submerging the seeds in the storage chamber 16. Then, close the water supply device. Next, open the air supply device connected to the inlet pipe 2. The air supply device delivers clean oxygen through the inlet pipe 2 to the distribution pipe 3, and then sprays it upwards through multiple nozzles 20 connected above the distribution pipe 3, so that the oxygen... The water is sprayed out in a fine mist by the nozzle 20, forming dense, tiny bubbles that agitate the water flow and create a micro-impact on the seeds in the storage chamber 16. This promotes contact between the seeds, clean water, and oxygen, resulting in uniform germination. Once germination is successful, all external devices can be turned off. Then, the storage chamber 16 can be removed from the water tank 1 using the handle 22. The germinated seeds can then be removed. After all seeds have germinated, they can all be removed, and the storage chamber 16 can be placed back into the water tank 1. Finally, the valve connected to the outlet 19 can be opened to drain the water.

[0036] Please see Figures 3-5 As a further implementation of the overall equipment: a movable spring 23 is connected to one side of the locking sleeve 9. The movable spring 23 is sleeved on the outside of the movable rod 12, and the other end of the movable spring 23 is in contact with the movable plate 10.

[0037] The locking block 13 has a locking groove 24, and the adjusting sleeve 4 has multiple locking rails 25 connected to one side. The locking groove 24 is adapted to the locking rails 25.

[0038] The adjusting plate 5 has multiple adjusting holes 26.

[0039] A locking wheel 27 is provided on one side of the locking block 13, which is rotated and engages between the two locking blocks 15.

[0040] Multiple anti-slip strips are provided on the outer sides of the adjusting sleeve 4, locking sleeve 9 and movable plate 10.

[0041] More specifically, when the oxygen delivery rate needs to be adjusted adaptively, firstly, rotate the movable plate 10 so that it drives the movable hole 11 to rotate to a position concentric with the movable rod 12. Then, push the locking sleeve 9. The locking sleeve 9 will drive the movable rod 12 to gradually pass into the movable hole 11, and the locking sleeve 9 will cooperate with the movable plate 10 to compress the movable spring 23. Then, the inner wall of the locking sleeve 9 will no longer limit the outer side of the locking wheel 27. Then, rotate the adjusting sleeve 4 in the forward direction to fix the input pipe 2 so that the input pipe 2 does not rotate. The adjusting sleeve 4 will drive the locking rail 25 on one side to rotate in the forward direction. Then, the locking rail 25 will drive the lock through the locking groove 24. When the locking block 13 rotates forward, it causes the locking wheel 27 on one side to move out from between the two locking blocks 15. The locking wheel 27 then causes the locking block 13 to slide outward along the locking rail 25 and the locking groove 24. The locking block 13 then causes the locking spring 14 to stretch outward. Simultaneously, the adjusting sleeve 4 moves the adjusting plate 5 via the movable shaft 8. The adjusting plate 5 then moves the adjusting shaft 6 on the other side along the adjusting groove 7, causing multiple adjusting plates 5 to gradually move outward along the adjusting groove 7. The adjusting plates 5 also cause multiple adjusting holes 26 to move outward. The change in position of the adjusting holes 26 and the outward movement of the adjusting plates 5 cause... The internal flow area of ​​the pipeline is expanded to adjust the oxygen delivery speed. After adjusting to a suitable delivery speed, the rotation of the adjusting sleeve 4 is stopped, and the locking rail 25 and locking groove 24 cooperate to drive the locking block 13 to rotate between the corresponding two locking blocks 15. Then, the locking spring 14 resets and pulls the locking block 13 to slide inward along the locking rail 25 and locking groove 24. Then, the locking block 13 drives one side locking wheel 27 to engage between the corresponding two locking blocks 15. Then, the locking sleeve 9 is released, and the movable spring 23 pushes the locking sleeve 9 to slide back to its original position. The locking sleeve 9 will also drive the movable rod 12 to slide back to its original position. When the movable spring 23 is fully reset, the movable rod 12... The moving rod 12 moves back to the side of the movable plate 10, and then the movable plate 10 is rotated again, causing the movable plate 10 to drive the movable hole 11 to rotate and reset to a position that does not correspond to the moving rod 12. Then the moving rod 12 supports the locking sleeve 9 to prevent the locking sleeve 9 from sliding easily. Then the inner wall of the locking sleeve 9 limits the outer wall of the locking wheel 27, so that the locking wheel 27 and the locking block 13 cannot slide, thereby limiting the adjustment sleeve 4 and preventing the adjustment sleeve 4 from rotating. This ensures the structural stability after the oxygen delivery speed is adjusted, ensures the stable delivery of oxygen, and thus ensures the stable progress of the germination work and the final quality.

[0042] In summary, when using or operating the entire equipment: First, ensure that the valve connected to the outlet 19 is closed. Then, place the seeds into the storage chamber 16. Next, open the water supply device connected to the inlet pipe 18 to deliver clean water into the water tank 1, gradually submerging the seeds in the storage chamber 16. Then, close the external water supply device. Next, open the air supply device connected to the input pipe 2. The air supply device will then deliver clean oxygen through the input pipe 2 to the distribution pipe 3, and then spray it upwards through multiple nozzles 20 connected above the distribution pipe 3. This allows oxygen to be sprayed out in a finer mist from the nozzle 20, forming dense, tiny bubbles that agitate the water flow and create a micro-impact on the seeds in the storage chamber 16. This promotes contact between the seeds, clean water, and oxygen, resulting in uniform germination. Once germination is successful, all external devices can be turned off. Then, the storage chamber 16 can be removed from the water tank 1 using the handle 22. The germinated seeds can then be removed. After all seeds have germinated, they can all be removed. The storage chamber 16 can then be placed back into the water tank 1, and the water can be drained by opening the valve connected to the outlet 19.

[0043] When the oxygen delivery rate needs to be adjusted adaptively, first rotate the movable plate 10, causing the movable plate 10 to rotate the movable hole 11 to a position concentric with the movable rod 12. Then push the locking sleeve 9, which will cause the movable rod 12 to gradually pass into the movable hole 11. The locking sleeve 9 and the movable plate 10 will cooperate to compress the movable spring 23. Then the inner wall of the locking sleeve 9 will no longer limit the outer side of the locking wheel 27. Then rotate the adjusting sleeve 4 in the forward direction to fix the input pipe 2 so that the input pipe 2 does not rotate. The adjusting sleeve 4 will drive the locking rail 25 on one side to rotate in the forward direction. Then the locking rail 25 will drive the locking block 13 through the locking groove 24. Rotating forward causes the locking block 13 to move the locking wheel 27 on one side out from between the two locking blocks 15. The locking wheel 27 then causes the locking block 13 to slide outward along the locking rail 25 and the locking groove 24. The locking block 13 then causes the locking spring 14 to stretch outward. Simultaneously, the adjusting sleeve 4 moves the adjusting plate 5 via the movable shaft 8. The adjusting plate 5 then moves the adjusting shaft 6 on the other side along the adjusting groove 7, causing multiple adjusting plates 5 to gradually move outward along the adjusting groove 7. The adjusting plates 5 also cause multiple adjusting holes 26 to move outward. The change in position of the adjusting holes 26 and the outward movement of the adjusting plates 5 cause changes in the position of the pipe... The increased flow area allows for adjustment of the oxygen delivery speed. Once the appropriate delivery speed is achieved, the rotating adjusting sleeve 4 is stopped, causing the locking rail 25 and locking groove 24 to engage and rotate the locking block 13 between the corresponding two locking blocks 15. Then, the locking spring 14 resets, pulling the locking block 13 inward along the locking rail 25 and locking groove 24. The locking block 13 then drives one locking wheel 27 to engage between the corresponding two locking blocks 15. The locking sleeve 9 is then released, and the movable spring 23 pushes the locking sleeve 9 to slide back to its original position. The locking sleeve 9 also drives the movable rod 12 to slide back to its original position. Once the movable spring 23 has fully reset, the movable rod... 12 moves back to the side of the movable plate 10, and then rotates the movable plate 10 again, so that the movable plate 10 drives the movable hole 11 to rotate and reset to a position that does not correspond to the movable rod 12. Then the movable rod 12 supports the locking sleeve 9 to prevent the locking sleeve 9 from sliding easily. Then the inner wall of the locking sleeve 9 limits the outer wall of the locking wheel 27, so that the locking wheel 27 and the locking block 13 cannot slide, thereby limiting the adjustment sleeve 4 and preventing the adjustment sleeve 4 from rotating. This ensures the structural stability after the oxygen delivery speed is adjusted, ensures the stable delivery of oxygen, and thus ensures the stable progress of the germination work and the final quality.

For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents.
