Description

Technical Field

[0001] The present invention relates to the technical field of seedling raising devices, and particularly relates to a device for raising seedlings of legume seeds. Background Art

[0002] Legume seedling raising equipment is specifically used for cultivating legume seedlings, and generally consists of parts such as a seedling tray, a substrate container, a moisturizing system, a drainage structure, and auxiliary accessories. The seedling tray adopts a porous cell design, which is convenient for separating and managing seeds. The material is mostly plastic or degradable material to ensure independent root growth. The substrate container is filled with a loose and breathable seedling raising substrate, such as coconut coir, vermiculite, or nutrient soil, to provide nutrients and support for seed germination. The moisturizing system includes a transparent cover or film covering, and some high-end devices are also equipped with an automatic spraying function to maintain appropriate humidity and temperature and promote rapid seed germination. Drainage holes or diversion grooves are provided at the bottom to avoid waterlogging and causing seed rot.

[0003] Chinese Patent Publication No. CN215684000U discloses a seedling raising device for bean sprouts production, including a base, a control box, a box body, a water tank, a collection box, a seedling tray, and a watering mechanism. The inner wall surface of the seedling tray is slidably connected with a placement groove, and a water filtering hole is opened at the bottom end of the inner wall surface of the placement groove. An electromagnetic valve is fixedly connected to the outer wall surface of the seedling tray. The watering mechanism includes a water pump, a first water pipe, a controller, and a sprinkler head. The water tank is fixedly connected to the outer wall surface of the top end of the base. By placing a placement groove on the top of the seedling tray, it is convenient to put seeds into the placement groove. And by filling the seedling tray with water, when the seeds germinate, the placement groove can be slid out from the inside of the seedling tray, and water filtering holes are opened at the bottom end of the placement groove, which is convenient for separating water from the seeds. And by controlling the electromagnetic valve to open through the controller, the water flows into the collection box through the second water pipe, which is convenient for preventing workers from damaging the newly germinated seeds when separating the seeds from the water, resulting in seed loss and affecting germination.

[0004] During the use of the device in the above patent document, although it can achieve the effect of raising seedlings for beans, in actual use, it is impossible to automatically screen the soaked beans, so that the bad beans and the good beans compete for nutrients, thereby reducing the subsequent seedling raising efficiency.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0039] Further, the seedling raising assembly 5 includes a slider 51. A threaded hole 52 penetrating through the lower end of the slider 51 is provided at the upper end of the slider 51. A bearing plate 53 is fixedly connected to the rear end of the slider 51. On the left and right sides of the upper front horizontal part of the bearing plate 53, photoelectric water level sensors 54 are fixedly connected. A scraping plate 55 is slidably connected to the upper parts of the front side wall and the rear side wall of the inner surface of the bearing plate 53. An L-shaped top plate 56 is fixedly connected to the lower right end of the bearing plate 53. A water injection port 57 penetrating through the right end of the bearing plate 53 is provided at the lower middle part of the left end of the bearing plate 53. Chute grooves 58 are provided at the middle parts of the left end and the right end of the bearing plate 53. A cultivation assembly 59 is slidably mounted on the inner surface of the bearing plate 53. A number of impact assemblies 595 are fixedly mounted in a linear array on the lower part of the rear side wall of the inner surface of the bearing plate 53. Three water retaining assemblies 50 are fixedly mounted in a linear array on the left side wall of the inner surface of the right water storage tank 21.

[0040] Further, the cultivation assembly 59 includes a seedling raising plate 591. Guide bars 592 are fixedly connected to both the left end and the right end of the seedling raising plate 591. A number of bearing holes 593 penetrating through the lower end of the seedling raising plate 591 are arranged in an array at the upper end of the seedling raising plate 591. A communicating hole 594 is provided in common on one side where the bearing holes 593 are close to each other. The upper parts of the inner surfaces of the bearing holes 593 are all arc-shaped.

[0041] Further, the impact component 595 includes a connecting rope 5951 fixedly connected to the lower part of the rear side wall of the inner surface of the bearing plate 53. The other end of the connecting rope 5951 is fixedly connected with an impact ball 5952. A number of flow disturbance holes 5953 are formed on the outer surface of the impact ball 5952, and three flow disturbance balls 5954 are arranged in the inner cavity of the impact ball 5952.

[0042] Further, the water blocking component 50 includes a water blocking plate 501. Four rectangular plates 502 are fixedly connected to the right end of the water blocking plate 501 in a linear array. Three springs 503 are fixedly connected to the rear ends of the four rectangular plates 502 in a linear array. A convex block 504 is fixedly connected to the lower part of the front ends of the four rectangular plates 502. The convex block 504 and the water blocking plate 501 are respectively located on the inner surface of the same side water outlet groove 22.

[0043] Further, the driving component 6 includes a first fixing block 61 fixedly connected to the lower side of the middle part of the front end of the storage box 3. A housing 62 is fixedly connected to the middle part of the right side of the front end of the storage box 3. A motor 63 is fixedly connected to the top wall of the housing 62. A second fixing plate 64 is fixedly connected to the upper part of the right side of the rear end of the seedling raising box 2. A first belt pulley 65 is rotatably connected to the upper end of the second fixing plate 64. The inner surface of the first belt pulley 65 is fixedly connected to the output end of the motor 63 through a coupling. A second belt pulley 66 is rotatably connected to the lower end of the first fixing block 61. A transmission belt 67 is wound around the outer surfaces of the second belt pulley 66 and the first belt pulley 65. A threaded rod 68 is fixedly connected to the inner surface of the second belt pulley 66. A limiting groove 69 penetrating the inner surface of the seedling raising box 2 is formed in the middle part of the front end of the seedling raising box 2. A third fixing plate 60 is fixedly connected to the lower side of the middle part of the rear end of the seedling raising box 2. The upper end of the third fixing plate 60 is rotatably connected to the lower end of the threaded rod 68.

[0044] Further, the three sliders 51 are all slidably connected to the inner surface of the limiting groove 69, and the three threaded holes 52 are all threadedly connected to the threaded rod 68.

[0045] First, lift the cover plate 31 from the upper end of the storage box 3. Then, pour the water required for seedling raising into the inner cavity of the storage box 3. Then, cover the cover plate 31. Then, sprinkle the beans to be cultivated on the upper ends of the three seedling raising plates 591 respectively. As can be seen from the above, the upper parts of the inner surfaces of a number of bearing holes 593 formed on the upper ends of the three seedling raising plates 591 are all arc-shaped. Therefore, during the process of pulling the scraping plate 55, the beans can be pushed into the bearing holes 593. The beans with a diameter smaller than the inner diameter of the bearing holes 593 are defective products that cannot be used for seedling raising and will fall to the bottom wall of the bearing plate 53. Then, the beans clamped in the inner cavity of the bearing holes 593 are used for subsequent seedling raising.

[0046] When raising seedlings for the first time, just start the motor 63, so that the output end of the motor 63 drives the pulley one 65 fixedly connected thereto to rotate on the upper end of the fixing plate two 64 through a coupling. A transmission belt 67 is wound around the outer surfaces of the pulley one 65 and the pulley two 66, and the upper end of the pulley two 66 is rotatably connected to the fixing block one 61. Therefore, the pulley two 66 rotates under the action of the transmission connection of the transmission belt 67;

[0047] When the pulley two 66 rotates, the threaded rod 68 fixedly connected to its inner surface also rotates on the upper end of the fixing plate three 60. The three sliders 51 are all slidably connected to the inner surface of the limiting groove 69, and the three threaded holes 52 are all threadedly connected to the threaded rod 68. Therefore, when the threaded rod 68 rotates, it can drive the three sliders 51 to move upward on the inner surface of the limiting groove 69 at the same time. When the three sliders 51 move upward, they can drive the bearing plate 53 fixedly connected thereto to move upward at the same time;

[0048] During the process of the three bearing plates 53 moving upward, the L-shaped top plate 56 fixedly connected to their lower ends will pass by the convex block 504 on the same side, and then squeeze the convex block 504 into the water outlet groove 22 on the same side. At this time, the motor 63 stops running;

[0049] When the convex block 504 is squeezed into the water outlet groove 22 on the same side, since the thickness of the water baffle 501 is less than the depth of the water outlet groove 22 on the same side, and the water injection port 57 and the water outlet groove 22 have the same size, the water outlet groove 22 corresponding to the water injection port 57 on the right side is kept interconnected. The water injection port 57 on the left side leaves the corresponding water inlet groove 23 and is blocked by the right inner side wall of the seedling raising box 2. Then start the water pump 32 on the right side, so that the input end of the water pump 32 on the right side pumps the water in the inner cavity of the cover plate 31 through the L-shaped pipe 34 into the water storage tank 21 on the right side. The water pumped into the water storage tank 21 will flow into the water injection port 57 through the water outlet groove 22 on the right side, and then gradually spread upward until the photoelectric water level sensor 54 senses the maximum water level, and then control the water pump 32 on the right side to stop injecting water. At this time, the water just submerges the beans;

[0050] After waiting for the beans to soak in water for about eight hours, the output end of the motor 63 can be reversed. During the process of its output end reversing, the threaded hole 52 drives the bearing plate 53 to move downward, so that the L-shaped top plate 56 no longer squeezes the convex block 504 on the same side. Under the action of the three springs 503 on the same side, the rectangular plate 502 rebounds to the initial state, so that the rectangular plate 502 drives the water baffle 501 and the convex block 504 on the same side to return to the initial state. At this time, the water baffle 501 and the convex block 504 on the same side block the water outlet groove 22 on the same side respectively;

[0051] When the carrier plate 53 moves to the initial state, the water injection port 57 on the right is communicated with the water inlet tank 23 on the right. Subsequently, water will flow into the water inlet tank 23 from the water injection port 57 and enter the water storage tank 21 on the left, waiting for the water in the water injection port 57 to drain;

[0052] When the water drains, a gauze can be covered on the surface of the beans to block light and avoid the influence of light on subsequent seedling cultivation;

[0053] When water flows in the water injection port 57, it will drive the impact balls 5952 fixedly connected by a number of connecting ropes 5951 to be disturbed. During the disturbance of the impact balls 5952, a number of turbulence balls 5954 are placed inside, and under the action of the turbulence holes 5953, the impact balls 5952 can produce a turbulence effect, thereby promoting the impact balls 5952 to irregularly impact the inner surface of the carrier plate 53, so that the surface of the carrier plate 53 generates vibration;

[0054] When vibration is generated on the surface of the carrier plate 53, the soaked or rotten beans can be shaken off the bearing holes 593, and then the shaken-off bad beans will enter the water storage tank 21 on the right along with the water flow;

[0055] When the water is drained and the gauze is covered on the surface of the beans, water needs to be added to the beans once in the morning and once in the evening. When water needs to be added, start the motor 63 to drive the carrier plate 53 to move upward. The subsequent operation steps are the same as those in the above, so no more details will be described. The difference is that there is no need to soak for eight hours later. It only needs to wait until the water spreads upward to the position where the communication holes 594 are located. The water level can be judged by two photoelectric water level sensors 54;

[0056] All the bearing holes 593 are interconnected through the communication holes 594. Therefore, when the water level spreads to the position of the communication holes 594, the water can fully contact the surface of the beans. Then, by starting the motor 63, the carrier plate 53 is moved downward. This process is the same as the above process, so no more details will be described about it;

[0057] The water entering the left water storage tank 21 can be pumped by starting the water pump 32 on the left. The lower end of the water suction pipe 35 is close to the bottom wall of the left water storage tank 21. Therefore, the input end of the water pump 32 can pump the water in the left water storage tank 21 upward through the L-shaped pipe 34 and the water suction pipe 35, and then inject it into the storage box 3 for recycling;

[0058] And during use, to prevent the rotten beans in the left water storage tank 21 from blocking the water suction pipe 35, a filter screen can be added at the lower end of the water suction pipe 35 to filter the rotten beans. At the same time, when the rotten beans need to be cleaned later, a door for cleaning can be opened at the lower left part of the seedling cultivation box 2 in this solution;

[0059] If there is no bad bean falling when several impact balls 5952 generate vibrations on the surface of the bearing plate 53, the beans staying on the surface of the bearing holes 593 at this time are the beans that can be normally used for seedling cultivation;

[0060] Repeat the above operations after soaking the beans about three to five days in sequence, and the seedling cultivation work can be completed.

[0061] The filter screen mentioned above is a conventional setting in the prior art. In this solution, it only needs to meet the requirement of filtering out bad beans, so this solution will not elaborate on it in detail;

[0062] The door opened at the lower left end of the seedling cultivation box 2 for cleaning mentioned above is a conventional setting in the prior art. In this solution, it only needs to meet the effect of taking out the bad beans inside the left water storage tank 21 later. Its specific shape, size and installation method are all conventional designs in the prior art, and this solution will not elaborate on it in detail;

[0063] The two photoelectric water level sensors 54 mentioned above are both conventional settings in the prior art. Their specific working principle is:

[0064] Utilize the refractive index difference of light in different media, air / liquid, to trigger a signal;

[0065] There are infrared LEDs and photosensitive receivers inside the photoelectric water level sensor 54;

[0066] When there is no water, the light is totally reflected to the receiver. When there is water, the light refracts into the liquid and the receiver signal weakens.

[0067] Therefore, the two photoelectric water level sensors 54 mentioned above are both conventional settings in the prior art. Their specific installation method, circuit connection method and control method all belong to conventional designs, and this solution will not elaborate on them in detail.

[0068] Embodiment 3. On the basis of Embodiment 2, this embodiment aims to take out the bean sprouts after the seedling cultivation is completed.

[0069] Specifically, referring to Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 12 , on the rear sides of the vertical parts at the upper ends of the bearing plates 53 close to each other, clamping grooves 511 are respectively opened. The inner surfaces of the two clamping grooves 511 are jointly and slidably connected with a limiting plate 513. On the rear sides of the middle parts of the bearing plates 53 close to each other, guiding grooves 512 are respectively opened. The guiding grooves 512 on the same side respectively penetrate through the clamping grooves 511 on the same side and communicate with the inner cavities of the sliding grooves 58 on the same side. The guiding strips 592 on the same side are respectively slidably connected to the inner surfaces of the sliding grooves 58 on the same side.

[0070] When it is necessary to take out the seedling-raising plate 591 after the seedling raising is completed, first open the observation door 4, and then sequentially pull up the three limiting plates 513 upwards, so that the left and right ends of the limiting plate 513 are disengaged from the two side slots 511 on both sides.
