Description

Technical Field

[0001] This invention relates to the field of seedling raising equipment technology, and in particular to a seedling raising sunroom. Background Technology

[0002] With the increasing demands for seedling quality and production efficiency in modern agriculture, seedling greenhouses, as an important component of facility agriculture, play a crucial role in optimizing the crop growth environment and improving seedling efficiency. However, existing seedling facilities still have many technical limitations, which restrict further improvement in seedling quality.

[0003] Traditional plant seedling cultivation facilities mainly rely on fixed greenhouse structures, whose lighting is limited by their inherent design. Static lighting design results in uneven light exposure for plants, affecting the uniformity and robustness of seedlings.

[0004] Traditional irrigation systems in seedling greenhouses largely rely on manual operation or simple timed irrigation, resulting in poor uniformity and water waste. Current greenhouse plant fertilization and irrigation technologies mostly require manual intervention, with room for improvement in automation. Uneven irrigation leads to inconsistent seedling growth, affecting overall seedling quality. Furthermore, the lack of a precise control mechanism based on actual water needs hinders efficient integrated water and fertilizer management.

[0005] The Chinese patent application CN202123061089.7 discloses a seedling nursery with an automatic repositioning function. Several culture trays are placed on a tray display platform, each capable of holding at least one floating seedling tray. Each culture tray is equipped with a corresponding seedling tray displacement and lifting comb. The frame also features a seedling tray lifting and repositioning mechanism that can move laterally along the length of the frame. This mechanism has transport combs that are aligned horizontally with each row of seedling trays. The transport combs and the seedling tray displacement and lifting combs work together to move the seedling trays vertically. The seedling nursery described in the above-mentioned literature suffers from the aforementioned problem of uneven light and irrigation. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seedling sunroom.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A seedling greenhouse includes a frame with multiple transparent panel modules mounted on it. A seedling system is housed within the frame, comprising an irrigation device and a cultivation device. The cultivation device includes: The mounting frame has a rotating platform mounted on it via a pivot. The rotating platform is used to support the seedling containers. Multiple rotating platforms are arranged linearly at equal intervals. Ring gear, the ring gear is rotatably mounted on the outside of the turntable; The first one-way limiting component causes the turntable to rotate in one direction along with the ring gear when the ring gear rotates. Angle adjustment mechanism, used to control the rotation of the ring gear; The irrigation device is used to irrigate each seedling container.

[0008] As a preferred embodiment of the present invention, the angle adjustment mechanism comprises: The mounting box is installed on one side of the frame and has a transparent structure. The main airbag is installed in the installation box. An elastic airbag is fixed on one side of the main airbag. The main airbag and the elastic airbag are connected internally. The elastic airbag has a deformable pleated structure on the outside. Guide seat, the guide seat is fixed to one side of the mounting bracket, and a slide is slidably connected inside the guide seat. One end of the slide is fixed to the end of the elastic airbag away from the main airbag. The rack has its end fixedly connected to the end of the carriage, and it meshes with each ring gear.

[0009] As a preferred embodiment of the present invention, the first unidirectional limiting component includes: Upper ratchet, the upper ratchet is fixed to the outer wall of the bottom of the turntable; The first guide frame is fixed to the outer wall of the bottom of the ring gear; The first one-way limiting tooth block is slidably connected to the inner wall of the first guide frame, and the first one-way limiting tooth block and the first guide frame are connected by a first spring.

[0010] As a preferred embodiment of the present invention: a second unidirectional limiting component is mounted on the mounting bracket, the second unidirectional limiting component comprising: The second guide frame has one end fixed to the mounting frame; The lower ratchet is mounted on the rotating shaft of the turntable; The second one-way limiting tooth block is slidably mounted on the inner wall of the second guide frame, and one end of the second one-way limiting tooth block is connected to the second guide frame by a second spring.

[0011] As a preferred embodiment of the present invention, the irrigation device comprises: Liquid supply device, with a liquid tank support installed at the bottom of the liquid supply device; The delivery pipe is installed at the output end of the liquid supply device. The support frame has a rotatable mounting shaft. A circumferentially distributed liquid box is fixed on the outside of the mounting shaft. A leak is provided on the side of the liquid box away from the mounting shaft. The position of the leak is adapted to the position of the turntable. The end of the delivery pipe extends to the side of the mounting shaft near the turntable. When the liquid box rotates to the side of the mounting shaft near the turntable, its opening faces upward to receive the water output from the delivery pipe.

[0012] As a preferred embodiment of the present invention: the liquid box is provided with equally spaced grooves, the position of the grooves is adapted to the turntable, the liquid box is provided with guide blocks, the guide blocks and the grooves are staggered, and the two sides of the guide blocks are inclined structures. When the liquid box moves to the side of the mounting shaft close to the turntable and is in a horizontal state, the height of the outlet is higher than the groove, but lower than the height of the top surface of the guide block.

[0013] As a preferred embodiment of the present invention: an annular seat is fixed on the support frame, a turntable is fixed on the mounting shaft, an elastic protrusion is fixed on the outer side of the turntable, an annular plate is fixed on the inner side of the annular seat, and a groove adapted to the elastic protrusion is opened on the annular plate, the position of the elastic protrusion corresponds one-to-one with the liquid box; the turntable rotates in the annular seat.

[0014] As a preferred embodiment of the present invention, a counterweight is fixed to one side of the outer wall of the liquid box.

[0015] As a preferred embodiment of the present invention, the top of the skeleton has an arc-shaped structure.

[0016] As a preferred embodiment of the present invention: a mounting base is installed on one side of the outer wall of the liquid box, and a counterweight is used in conjunction with the mounting base. Both the counterweight and the mounting base have threaded grooves on one side, and a stud is provided on the other side of the counterweight. The counterweight is detachably installed in the threaded groove of another counterweight or the mounting base through the stud.

[0017] The beneficial effects of this invention are as follows: This invention, through the design of a main airbag and elastic airbags, enables the rack to reciprocate based on the thermal expansion and contraction of the gas inside the main airbag. During this process, it drives the ring gear and turntable to rotate, thereby adjusting the angle of the seedling container. This allows the plants inside the seedling container to receive sufficient light from multiple angles. Because a transparent installation box is used, under sufficient light conditions, the temperature inside the main airbag is affected by the light, which in turn drives the rack to move better under higher light intensity, allowing the plants inside the seedling container to receive better light.

[0018] This invention, by setting a first one-way limiting component and a second one-way limiting component, enables the turntable to rotate with the ring gear during the rotation of the rack. In this case, the first one-way limiting component limits the rotation, with the first one-way limiting tooth block engaging the upper ratchet, while the second one-way limiting component does not limit the rotation. The second one-way limiting tooth block, under the deformation of a second spring, avoids the lower ratchet, allowing the turntable to rotate. When the rack moves in the opposite direction, the ring gear rotates in the opposite direction. In this case, the first one-way limiting component does not limit the rotation, with the first one-way limiting tooth block, under the deformation of the first spring, avoids the upper ratchet, while the second one-way limiting component limits the rotation, with the second one-way limiting tooth block engaging the lower ratchet, allowing the ring gear to rotate while the turntable cannot. Based on this scheme, the goal of allowing the turntable to rotate only in one direction is achieved. This method avoids insufficient rack travel, which could prevent the turntable from failing to achieve a movement of more than 360°, thus preventing uneven light exposure to the plants and improving reliability.

[0019] This invention, by setting up structures such as liquid boxes, enables water to be output through a delivery pipe based on a liquid supply device, so that the water reaches the liquid box. As the amount of water in the liquid box increases, the mounting shaft rotates due to gravity, and then the water is input into each seedling container through the leak.

[0020] This invention, by setting grooves and guide blocks, allows water to first fill the groove below the delivery pipe when it enters the liquid box. As the groove is filled, the water gradually overflows into other grooves. Finally, when the liquid box rotates, the corresponding grooves can output water to the corresponding seedling containers, achieving uniform irrigation. The guide blocks act as guides, preventing water from being spilled between two seedling containers.

[0021] This invention, through the design of a turntable, elastic protrusions, annular seats, and annular plates, enables the liquid box to temporarily stop rotating when water is output from the delivery pipe. This is achieved by the engagement of the elastic protrusions and the slots. As the water fills the slots, the elastic protrusions deform under pressure, disengaging from the current slot. The turntable and mounting shaft then rotate, pouring the water into each seedling container. Finally, as the turntable rotates, the elastic protrusions move to the next slot and engage again. This process is repeated, achieving uniform irrigation and avoiding the problem of the liquid box rotating before the slots are fully filled. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1: A seedling greenhouse, such as Figure 1-6 As shown, it includes a frame 1, on which multiple transparent panel modules are installed. A seedling system is set inside the frame 1, and the seedling system includes an irrigation device and a cultivation device.

[0032] The cultivation device includes a mounting frame 4, a ring gear 12, a first one-way limiting component, and an angle adjustment mechanism.

[0033] In this embodiment, a turntable 15 is rotatably mounted on the mounting frame 4 via a rotating shaft. The turntable 15 is used to support the seedling container 5, and multiple turntables 15 are arranged linearly at equal intervals.

[0034] In this embodiment, the ring gear 12 is rotatably mounted on the outside of the turntable 15.

[0035] In this embodiment, the first one-way limiting component causes the turntable 15 to rotate unidirectionally following the ring gear 12 when the ring gear 12 rotates.

[0036] In this embodiment, the angle adjustment mechanism is used to control the rotation of the ring gear 12, while the irrigation device is used to perform irrigation operations on each seedling container 5.

[0037] To facilitate control of the rotation of the ring gear 12; such as Figure 2 , Figure 3 , Figure 4 As shown, the angle adjustment mechanism includes a mounting box 6, a main airbag 7, a guide seat 13, and a rack 10.

[0038] In this embodiment, the mounting box 6 is installed on one side of the frame 1. The mounting box 6 is a transparent structure. The main airbag 7 is installed inside the mounting box 6. An elastic airbag 9 is fixed on one side of the main airbag 7. The main airbag 7 and the elastic airbag 9 are internally connected. The outer side of the elastic airbag 9 is provided with a pleated structure that is easy to deform. The guide seat 13 is fixed on one side of the mounting frame 4. A slide 14 is slidably connected inside the guide seat 13. One end of the slide 14 is fixed to the end of the elastic airbag 9 away from the main airbag 7. The end of the rack 10 is fixedly connected to the end of the slide 14. The rack 10 meshes with each ring gear 12.

[0039] By setting up structures such as the main airbag 7 and the elastic airbag 9, the rack 10 can reciprocate based on the thermal expansion and contraction of the gas inside the main airbag 7. During this process, it can drive the ring gear 12 and the turntable 15 to rotate, thereby adjusting the angle of the seedling container 5. This allows the plants in the seedling container 5 to receive sufficient light from multiple angles. Because the installation box 6 has a transparent structure, under sufficient light conditions, the temperature inside the main airbag 7 can be affected by the light, thus better driving the rack 10 to move under higher light intensity, allowing the plants in the seedling container 5 to receive better light.

[0040] Preferably, a convex lens can be installed on the outside of the mounting box 6 to allow sunlight to better heat the main airbag 7, thereby increasing the influence of sunlight on angle adjustment.

[0041] To enable the turntable 15 to move in one direction following the ring gear 12; such as Figure 3 , Figure 4 As shown, the first one-way limiting component includes an upper ratchet 22, a first guide frame 21, and a first one-way limiting tooth block 20.

[0042] In this embodiment, the upper ratchet 22 is fixed to the bottom outer wall of the turntable 15, the first guide frame 21 is fixed to the bottom outer wall of the ring gear 12, the first one-way limiting tooth block 20 is slidably connected to the inner wall of the first guide frame 21, and the first one-way limiting tooth block 20 and the first guide frame 21 are connected by the first spring 19.

[0043] To better limit the movement of turntable 15; such as Figure 3 , Figure 4As shown, a second one-way limiting component is installed on the mounting bracket 4. The second one-way limiting component includes a second guide bracket 24, a lower ratchet 26, and a second one-way limiting tooth block 25.

[0044] In this embodiment, one end of the second guide frame 24 is fixed to the mounting frame 4, the lower ratchet 26 is mounted on the rotating shaft of the turntable 15, and the second one-way limiting tooth block 25 is slidably mounted on the inner wall of the second guide frame 24. One end of the second one-way limiting tooth block 25 is connected to the second guide frame 24 by the second spring 23.

[0045] By setting a first one-way limiting component and a second one-way limiting component, the rack 10 can rotate clockwise as viewed from above during the rotation of the ring gear 12. At this time, the first one-way limiting component limits the rotation, and the first one-way limiting tooth block 20 engages the upper ratchet 22, while the second one-way limiting component does not limit the rotation. The second one-way limiting tooth block 25 avoids the lower ratchet 26 under the deformation of the second spring 23, allowing the turntable 15 to rotate with the ring gear 12. When the rack 10 moves in the opposite direction, the ring gear 12 rotates in the opposite direction, corresponding to a counterclockwise rotation as viewed from above. At this time, the first one-way limiting component... The one-way limiting component is not limited. The first one-way limiting tooth block 20 avoids the upper ratchet 22 under the deformation of the first spring 19, while the second one-way limiting component limits the ratchet 26. The second one-way limiting tooth block 25 clamps the lower ratchet 26, so that the ring gear 12 can rotate, but the turntable 15 cannot rotate. Based on the above scheme, the purpose of the turntable 15 can only rotate in one direction is achieved. This method can avoid the situation where the rack 10 has insufficient stroke, which would cause the turntable 15 to fail to achieve an angle of more than 360°, thus resulting in uneven light exposure to the plants and improving reliability.

[0046] To facilitate irrigation operations; such as Figure 1 , Figure 2 , Figure 3 As shown, the irrigation device includes a liquid supply device 2, a delivery pipe 8, and a support frame 11.

[0047] In this embodiment, a liquid tank bracket 3 is installed at the bottom of the liquid supply device 2, and a delivery pipe 8 is installed at the output end of the liquid supply device 2. An installation shaft 29 is rotatably installed on the support frame 11. A circumferentially distributed liquid box 16 is fixed on the outside of the installation shaft 29. A leak is provided on the side of the liquid box 16 away from the installation shaft 29. The position of the leak is adapted to the position of the turntable 15. The end of the delivery pipe 8 extends to the side of the installation shaft 29 near the turntable 15. When the liquid box 16 rotates to the side of the installation shaft 29 near the turntable 15, its opening faces upward and is used to receive the water output by the delivery pipe 8.

[0048] By setting up structures such as liquid box 16, water can be output through delivery pipe 8 based on liquid supply device 2, so that water reaches liquid box 16. As the amount of water in liquid box 16 increases, the mounting shaft 29 rotates based on gravity, and then water is input into each seedling container 5 through the leak.

[0049] To ensure more even watering; such as Figure 3 As shown, the liquid box 16 has equally spaced grooves 17 inside, the position of which is adapted to the turntable 15. A guide block 18 is provided inside the liquid box 16. The guide block 18 and the grooves 17 are staggered, and the two sides of the guide block 18 are inclined. When the liquid box 16 moves to the side of the mounting shaft 29 close to the turntable 15 and is in a horizontal state, the height of the outlet is higher than the grooves 17, but lower than the height of the top surface of the guide block 18.

[0050] By setting the groove 17 and the guide block 18, when the water enters the liquid box 16, it first fills the groove 17 below the delivery pipe 8. As the groove 17 is filled, the water gradually overflows into the other grooves 17. Finally, when the liquid box 16 rotates, the corresponding groove 17 can output the water to the corresponding seedling container 5, so as to achieve uniform irrigation. The guide block 18 plays a guiding role to prevent the water from being spilled between the two seedling containers 5.

[0051] To ensure that a certain amount of water is collected before irrigation; for example... Figure 5 As shown, an annular seat 30 is fixed on the support frame 11, and a turntable 28 is fixed on the mounting shaft 29. Circumferentially distributed elastic protrusions 27 are fixed on the outer side of the turntable 28. An annular plate 32 is fixed on the inner side of the annular seat 30. The annular plate 32 has slots 31 that are adapted to the elastic protrusions 27. The positions of the elastic protrusions 27 correspond one-to-one with the liquid box 16. The turntable 28 rotates within the annular seat 30.

[0052] By setting up structures such as turntable 28, elastic protrusion 27, annular seat 30, and annular plate 32, when water is output from the delivery pipe 8, the liquid box 16 can temporarily stop rotating based on the engagement of the elastic protrusion 27 and the slot 31. As the water fills each groove 17, the elastic protrusion 27 is squeezed and deformed, disengaging from the current slot 31. The turntable 28 and the mounting shaft 29 rotate, pouring the water into each seedling container 5. Finally, as the turntable 28 rotates, the elastic protrusion 27 moves to the next slot 31 and engages again. This process is repeated, achieving uniform irrigation and avoiding the problem of the liquid box 16 rotating when the groove 17 is not full.

[0053] like Figure 5 As shown, a counterweight 33 is fixed to one side of the outer wall of the liquid box 16.

[0054] like Figure 1 As shown, the top of the skeleton 1 has an arc-shaped structure.

[0055] Example 2: A seedling greenhouse, such as Figure 1 As shown, in order to facilitate the adjustment of the counterweight, this embodiment makes the following improvements based on embodiment 1: a mounting base 35 is installed on one side of the outer wall of the liquid box 16, and a counterweight 33 is used in conjunction with the mounting base 35. A threaded groove 34 is provided on one side of both the counterweight 33 and the mounting base 35, and a stud is provided on the other side of the counterweight 33. The counterweight 33 can be detachably installed in the threaded groove 34 of another counterweight 33 or the mounting base 35 through the stud.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
