Description

Technical Field

[0001] This invention relates to the field of seed breeding and germination technology, and in particular to a modular seed breeding and germination device. Background Technology

[0002] In existing seed germination devices, such as the circulating soaking and germination device disclosed in CN105684869B, a rotating cultivation rack structure is used. A transmission system causes the seedling trays to pass sequentially through a light-emitting zone and a liquid-soaking zone, achieving alternating nutrient supply and light exposure for the seeds. This device achieves a certain degree of automation, reducing manual intervention, and provides water and nutrients to the seeds through periodic soaking. However, this type of device still has significant drawbacks: First, the seedling trays often rotate or become unstable during rotation, causing seeds to shift or even accumulate within the trays. This not only affects the uniformity of germination but also makes it easier for the already germinated young shoot tips to break due to mechanical compression, severely impacting the germination survival rate and seedling quality. Second, the nutrient solution usually uses an open circulation or soaking method, with insufficient precision in controlling the liquid level and soaking time. This easily leads to the large-scale exposure, evaporation, and deterioration of the nutrient solution, resulting in resource waste and potentially causing seeds to float or rot due to lack of oxygen caused by excessive soaking.

[0003] Furthermore, the germination process of photosensitive seeds (such as lettuce, celery, basil, cyclamen, and petunia) depends on light stimulation. The phytochrome in their embryos needs to absorb specific wavelengths of red light to initiate physiological metabolism and break dormancy. However, existing equipment cannot reconcile the contradiction between light and moisture: continuous light, while meeting the light requirement, easily leads to excessively high temperatures and rapid water evaporation in the seedling tray, causing seed scorching or drying; while frequent soaking can replenish water and lower the temperature, it deprives the seeds of necessary light exposure time, prolonging the germination cycle and even causing germination failure. Most existing technologies employ intelligent control systems, adding lighting and water spraying mechanisms to the germination device, intelligently controlling the light and water spraying times. However, such products consume a lot of electricity, which is not conducive to the current environmental protection requirements of agricultural production. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a modular seed seedling germination device to solve the problems mentioned in the background art.

[0008] Preferably, the speed-regulating drive mechanism includes a bracket, a liquid storage tank is fixedly connected to the outside of the right side of the bracket, and sliding chambers are fixedly connected to the upper and lower ends of the inside of the right side of the bracket. A driving continuously variable speed wheel is slidably connected inside the lower sliding chamber, and a driven continuously variable speed wheel is slidably connected inside the upper sliding chamber. The driving continuously variable speed wheel and the driven continuously variable speed wheel are connected by a continuously variable speed steel belt. A dual-head motor is fixedly connected to the lower middle part of the bracket. A first driving gear is fixedly connected to the left driving end of the dual-head motor. A steering speed increaser is fixedly connected to the upper middle part of the bracket. A driving bevel gear is fixedly connected to the upper output end of the steering speed increaser. A driven bevel gear is meshed with the upper end of the driving bevel gear. A second driving shaft is fixedly connected to the middle part of the driven bevel gear.

[0009] Preferably, the left end of the bracket is fixedly connected to the middle right side of the water delivery mechanism, the liquid storage tank is connected to the interior of the lower sliding tank through a conduit, and the lower end of the drive gear meshes with the driven gear plate.

[0010] Preferably, the right drive end of the dual-head motor is fixedly connected to the left end of the drive continuously variable speed wheel, the right input end of the steering speed increaser is fixedly connected to the left end of the driven continuously variable speed wheel, and the front and rear ends of the second drive shaft are both fixedly connected to the inside of the second drive pulley.

[0011] Preferably, the water delivery mechanism includes a liquid storage tank, an soaking tank fixedly connected to the upper end of the liquid storage tank, a delivery tank fixedly connected to the middle of the front end of the liquid storage tank, a connecting pipe one fixedly connected to the lower water inlet end of the delivery tank, a connecting pipe two fixedly connected to the upper water outlet end of the delivery tank, an impeller rotatably connected to the middle of the delivery tank, a drive shaft one fixedly connected to the middle of the impeller, a driven pulley one fixedly connected to the front end of the drive shaft one, and a drive pulley one connected to the driven pulley one via a transmission belt one.

[0012] Preferably, the lower end of the first connecting pipe is connected to the lower inner part of the liquid storage tank, the upper end of the second connecting pipe is connected to the lower inner part of the soaking tank, and the rear end of the first driving pulley is fixedly connected to the front end of the second driven pulley.

[0013] The modular seed germination and seedling raising device provided by this invention has the following advantages: 1. The drive shaft three, driven pulley three, and transmission belt three drive the module germination mechanism to rotate inside the triangular frame, allowing all the module germination mechanisms to move to the sun-facing side in turn. At the same time, through the cooperation of drive gear two and rack and pinion belt, the connecting block and rotating inner frame are driven to rotate, thereby causing all the germination trays to rotate and take turns to be exposed to sunlight. Furthermore, through the cooperation of driven gear one and drive gear two, the opening of the germination tray always faces upward when rotating, and the seeds inside the germination tray will not be displaced. After all the germination trays move into the soaking tank, they can take turns soaking in the nutrient solution in the soaking tank, thereby keeping the seeds moist and providing nutrients for germination, and taking turns to be fully exposed to sunlight. After the seeds are exposed to sunlight and heated up, they move into the shade of the germination trays above to avoid excessive heating or excessive loss of nutrient solution due to continuous exposure to sunlight, which would affect the germination effect.

[0014] 2. By rotating the drive gear, in conjunction with the driven gear plate, the upper support rotation mechanism and the modular germination mechanism of the water delivery mechanism rotate, ensuring that the right-side modular germination mechanism always faces the sun to guarantee the effectiveness of sunlight. As the temperature gradually rises in the morning, the liquid inside the storage tank expands due to heat and enters the lower sliding tank, squeezing the lower continuously variable drive wheel to retract, thereby increasing the transmission ratio. This increases the revolution speed of all modular germination mechanisms around the support rotation mechanism, and simultaneously increases the revolution speed of all germination discs around the drive gear. This not only shortens the light exposure time for the seeds in all germination discs but also increases the frequency of nutrient solution soaking, allowing the seeds to maintain a relatively constant temperature for germination. As the temperature gradually drops in the afternoon, the liquid inside the lower sliding tank gradually contracts and flows back into the storage tank, while the upper sliding tank is pulled back to its original position due to air pressure, thus reducing the rotation speed. This achieves automatic adjustment of the germination disc rotation speed during the germination process, ensuring the germination effect.

[0015] 3. The driven pulley 1 and transmission belt 1 drive the driven pulley 1 to rotate, which in turn drives the impeller to rotate inside the infusion chamber via the drive shaft 1. This pumps the nutrient solution from the storage chamber into the soaking tank through connecting pipes 1 and 2. This prevents excessive nutrient solution from leaking out and deteriorating, thus avoiding waste. It also prevents seeds from floating in the nutrient solution due to excessive soaking depth. At the same time, as the speed of drive pulley 2 increases, the speed of the impeller also increases, resulting in more nutrient solution being pumped into the soaking tank. This ensures that the nutrient solution is increased in tandem with the speed of the germination tray, allowing the seeds in the germination tray to be fully soaked in the nutrient solution at all times.

[0016] 4. By cultivating seeds under outdoor sunlight for germination, the current mainstream intelligent control system that controls the lighting, nutrient solution spraying, and ventilation in the germination device is eliminated. This not only saves electricity consumption, which is in line with the current requirements for environmentally friendly agricultural production and saves farmers' electricity, but also results in seeds that germinate under natural conditions having stronger stress resistance potential and a higher survival rate after germination, which is beneficial to farmers' production needs.

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] like Figures 1-10 As shown, this embodiment proposes a modular seed germination device, including a water supply mechanism 2. A movable base 1 is rotatably connected to the lower end of the water supply mechanism 2. A driven gear 6 is fixedly connected to the outer periphery of the upper end of the movable base 1. A speed-regulating drive mechanism 3 is fixedly connected to the right side of the water supply mechanism 2. A supporting rotation mechanism 4 is fixedly connected to the upper end of the water supply mechanism 2. Modular germination mechanisms 5 are evenly distributed inside the supporting rotation mechanism 4. The modular germination mechanism 5 includes a germination disc 51, a connecting rod 54, and a rotating outer frame 56. Mounting devices are fixedly connected to the front and rear sides of the upper end of the germination disc 51. The groove 52 and the mounting groove 52 are both fitted with mounting blocks 53. The mounting blocks 53 are all fixedly connected to the outer periphery of the front and rear ends of the middle part of the connecting rod 54. The outer periphery of the front and rear ends of the connecting rod 54 are all fixedly connected with driven gear 55. The rotating outer frame 56 is rotatably connected to the side of the germination tray 51. The rotating inner frame 57 is fixedly connected to the middle part of the rotating inner frame 57. The side of the rotating rod 58 away from the germination tray 51 is fixedly connected with a connecting block 59. The side of the rotating rod 58 near the germination tray 51 is fixedly connected with a drive gear 510.

[0022] In this embodiment, the supporting rotation mechanism 4 includes a tripod 41. There are two tripods 41, and each tripod is rotatably connected to a drive shaft 42. The side of the drive shaft 42 closest to the germination tray 51 is fixedly connected to a driven pulley 43. The three driven pulleys 43 are connected by a transmission belt 44. The right end of the drive shaft 42 away from the germination tray 51 is fixedly connected to a driven pulley 45. The driven pulleys 45 are connected to a drive pulley 47 by a transmission belt 46. A rack and pinion belt 48 is fixedly connected to the outer periphery of the side of the tripod 41 closest to the germination tray 51.

[0023] In this embodiment, the second drive gear 510 meshes with the first driven gear 55 and the rack and belt 48. The front and rear ends of the connecting rod 54 are rotatably connected to the outer periphery of the middle of the rotating inner frame 57. The end of the rotating rod 58 away from the germination plate 51 is slidably connected to the middle of the tripod 41. The lower end of the tripod 41 is fixedly connected to the upper end of the water delivery mechanism 2.

[0024] In this embodiment, the speed-regulating drive mechanism 3 includes a bracket 31. A liquid storage tank 32 is fixedly connected to the outside of the right side of the bracket 31. Sliding tanks 33 are fixedly connected to the upper and lower ends of the right side of the bracket 31. A continuously variable speed wheel 34 is slidably connected inside the lower sliding tank 33, and a driven continuously variable speed wheel 35 is slidably connected inside the upper sliding tank 33. The driven continuously variable speed wheel 34 and the driven continuously variable speed wheel 35 are connected by a continuously variable speed steel belt 36. A double-headed motor 37 is fixedly connected to the lower middle part of the bracket 31. A drive gear 38 is fixedly connected to the left drive end of the double-headed motor 37. A steering speed increaser 39 is fixedly connected to the upper middle part of the bracket 31. A drive bevel gear 310 is fixedly connected to the upper output end of the steering speed increaser 39. A driven bevel gear 311 is meshed with the upper end of the drive bevel gear 310. A drive shaft 312 is fixedly connected to the middle part of the driven bevel gear 311.

[0025] In this embodiment, the left end of the bracket 31 is fixedly connected to the middle right side of the water delivery mechanism 2, the liquid storage tank 32 is connected to the interior of the lower sliding tank 33 through a conduit, and the lower end of the drive gear 38 meshes with the driven gear 6.

[0026] In this embodiment, the right drive end of the dual-head motor 37 is fixedly connected to the left end of the drive continuously variable speed wheel 34, the right input end of the steering speed increaser 39 is fixedly connected to the left end of the driven continuously variable speed wheel 35, and the front and rear ends of the drive shaft 2 312 are both fixedly connected to the inside of the drive pulley 2 47.

[0027] Specifically, the germination tray 51 containing seeds is installed between the rotating inner frame 57 via the mounting slot 52 and mounting block 53. After sunrise, the germination device is pushed outdoors, and the speed-regulating drive mechanism 3 is oriented towards the sun. The hydroponic germination nutrient solution is added into the storage tank 21. The dual-head motor 37 is started, which drives the driven continuously variable speed wheel 35 to rotate via the continuously variable speed belt 36 and the drive continuously variable speed wheel 34. This drives the drive bevel gear 310 to rotate via the steering speed increaser 39, which in turn drives the drive shaft 312 to rotate via the driven bevel gear 311. The driven belt pulley 47 and the transmission belt 46 then drive the driven belt pulley 45 to rotate. Simultaneously, the driven belt pulley 45 rotates via the drive shaft 42 and the driven belt pulley 46. The pulley 3 43 and the transmission belt 3 44 drive the modular germination mechanism 5 to rotate inside the tripod 41, allowing all the modular germination mechanisms 5 to move to the sun-facing side in turn. Simultaneously, through the engagement of the drive gear 2 510 and the rack and pinion belt 48, the connecting block 59 and the rotating inner frame 57 are driven to rotate, thereby causing all the germination trays 51 to rotate and take turns irradiating sunlight. Furthermore, through the engagement of the driven gear 1 55 and the drive gear 2 510, the opening of the germination tray 51 always faces upwards during rotation, preventing the seeds inside from shifting. And when all the germination trays 51 move into the soaking tank 22, they can take turns soaking in the nutrient solution within the soaking tank 22, thus moisturizing and... It provides nutrients for germination and alternates between full exposure to sunlight. After the temperature rises from sunlight, it moves into the shade of the germination tray 51 to avoid excessive heating or rapid loss of nutrient solution due to continuous sunlight, which would affect the germination effect. When the dual-head motor 37 drives the continuously variable speed drive wheel 34 to rotate, it synchronously rotates through the drive gear 38. In cooperation with the driven gear plate 6, it drives the support rotation mechanism 4 at the upper end of the water delivery mechanism 2 and the modular germination mechanism 5 to rotate, so that the right-side modular germination mechanism 5 can always face the sun to ensure the effect of light. When the temperature gradually rises in the morning, the liquid inside the liquid storage tank 32 expands due to heat and enters the lower sliding tank 33, squeezing the lower continuously variable speed drive wheel 31. The speed wheel 34 retracts, thereby increasing the transmission ratio and thus increasing the revolution speed of all the module germination mechanisms 5 around the supporting rotating mechanism 4. At the same time, it increases the revolution speed of all the germination discs 51 around the drive gear 2 510. This not only shortens the light exposure time of the seeds inside all the germination discs 51, but also increases the frequency of soaking in nutrient solution, so that the seeds can always maintain a relatively constant temperature for germination. As the temperature gradually drops in the afternoon, the liquid inside the lower sliding chamber 33 gradually contracts and flows back into the liquid storage chamber 32, while the upper sliding chamber 33 will also be pulled back to its original position due to the influence of air pressure, thereby reducing the rotation speed. This achieves automatic adjustment of the rotation speed of the germination discs 51 during the germination process, ensuring the germination effect.

[0028] It should be noted that the steering speed increaser 39 is an existing technology that achieves steering and speed increase. It adopts a structure similar to that disclosed in publication number CN207889805U, and its internal structure and working principle will not be described in detail here.

[0029] In this embodiment, the water delivery mechanism 2 includes a liquid storage tank 21. An soaking tank 22 is fixedly connected to the upper end of the liquid storage tank 21. A delivery tank 23 is fixedly connected to the middle of the front end of the liquid storage tank 21. A connecting pipe 24 is fixedly connected to the lower water inlet end of the delivery tank 23. A connecting pipe 25 is fixedly connected to the upper water outlet end of the delivery tank 23. An impeller 26 is rotatably connected to the middle of the delivery tank 23. A drive shaft 27 is fixedly connected to the middle of the impeller 26. A driven pulley 28 is fixedly connected to the front end of the drive shaft 27. The driven pulley 28 is connected to a drive pulley 210 through a transmission belt 29.

[0030] In this embodiment, the lower end of the first connecting pipe 24 is connected to the lower inner part of the liquid storage tank 21, the upper end of the second connecting pipe 25 is connected to the lower inner part of the soaking tank 22, and the rear end of the first driving pulley 210 is fixedly connected to the front end of the second driven pulley 45.

[0031] Specifically, when the driven pulley 25 rotates, it simultaneously drives the driven pulley 28 to rotate via the drive pulley 210 and the transmission belt 29. This, in turn, drives the impeller 26 to rotate inside the infusion chamber 23 via the drive shaft 27. Consequently, the nutrient solution inside the storage chamber 21 is pumped into the soaking tank 22 through the connecting pipe 24 and the connecting pipe 25. This prevents excessive leakage and spoilage of the nutrient solution, thus avoiding waste. It also prevents the seeds from floating in the nutrient solution due to excessive soaking depth. At the same time, as the speed of the drive pulley 27 increases, the speed of the impeller 26 also increases, resulting in more nutrient solution being pumped into the soaking tank 22. This ensures that the nutrient solution is increased simultaneously as the speed of the germination tray 51 increases, allowing the seeds in the germination tray 51 to be fully soaked in the nutrient solution at all times.

[0032] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
