Technical Field
[0001] This invention belongs to the field of vegetable seedling technology, and in particular relates to a seedling rack for vegetable planting. Background Technology
[0002] In the vegetable cultivation industry chain, seedling raising is a crucial foundational step that determines the subsequent growth quality and yield. To improve seedling raising efficiency and save cultivation space, seedling racks are widely used in greenhouses and seedling bases. Their main function is to provide a stable supporting platform for seedlings and, in conjunction with supplemental lighting equipment, meet their light requirements for growth. Currently, most vegetable seedling racks on the market adopt a horizontal multi-layer design, that is, by setting up several layers of horizontal placement boards to achieve layered placement of seedling trays.
[0003] Research has found that to ensure seedlings on each layer receive uniform light in a horizontally tiered seedling rack system, a complete cultivation light typically needs to be installed on each layer. This not only leads to high equipment purchase costs but also high operating energy consumption, resulting in high seedling costs. Summary of the Invention

[0005] The technical solution of the present invention is as follows: A seedling placement rack for vegetable cultivation includes an outer shell, a control module installed in the outer shell, a chassis inside the outer shell, circumferentially distributed support rods rotatably connected to the chassis, a fixed frame fixedly connected to the support rods, a plurality of pairs of support members arranged in a circular array on the fixed frame, each pair of support members jointly holding a cultivation tray, a cultivation lamp inside the outer shell located between all the support rods, the cultivation lamp being electrically connected to the control module, a drive mechanism on the chassis for driving the support rods to rotate, and a power mechanism on the fixed frame for driving all the support members on the same fixed frame to move.
[0006] Preferably, the cultivation lamp is a circular lamp tube.
[0007] Preferably, the axis of the cultivation lamp coincides with the axis of the chassis.
[0008] Preferably, the drive mechanism includes: a first motor, fixedly connected to the chassis and electrically connected to the control module; a drive gear, fixedly connected to the output shaft of the first motor, the drive gear being rotatably connected to the cultivation lamp; and a plurality of driven gears distributed circumferentially, each fixedly connected to an adjacent support rod, the driven gears meshing with the drive gears.
[0009] Preferably, the power mechanism includes a second motor, which is fixedly connected to the fixed frame and electrically connected to the control module. A chain drive module is installed on the fixed frame, and the second motor is used to drive the chain drive module. Several pairs of connecting frames are rotatably connected to the chain of the chain drive module in a circular array, and the connecting frames are fixedly connected to the adjacent support members.
[0010] Preferably, the fixing frame has symmetrically distributed guide grooves inside, and the connecting frame has a cross structure. The guide grooves are used to guide the crosses of adjacent connecting frames, so that the connecting frame can translate along the adjacent guide grooves.
[0011] Preferably, the system further includes: a third motor, fixedly connected to the housing and electrically connected to the control module; a drive frame, fixedly connected to the output shaft of the third motor; the fixed frame and the cultivation lamp are both rotatably connected to the drive frame; and the chassis is rotatably connected to the housing.
[0012] Preferably, each pair of the support members is slidably connected to a water replenishment tray, and the water replenishment tray is located on the lower side of the corresponding culture tray.
[0013] Preferably, an elastic element is fixedly connected between the support member and the adjacent water replenishment tray, and the elastic element is used to drive the adjacent water replenishment tray to move.
[0014] Preferably, the cultivation tray has evenly distributed water-absorbing elements on the side near the water replenishment tray.
[0015] Combining the above technical solutions, the beneficial effects of the present invention are as follows: The present invention concentrates the light source and heat by arranging the fixed frame circumferentially and placing the cultivation lamp between all the cultivation trays. At the same time, the fixed frame is used to arrange the cultivation trays vertically so that all seedlings can receive light, thereby achieving efficient use of space while reducing the number of cultivation lamps.
[0016] This invention uses the cooperation of a first motor and a second motor to make the fixed frame rotate while driving all the cultivation trays on it to move vertically, so that the seedlings on the cultivation trays are evenly irradiated by the cultivation lamp on the inside and outside.
[0017] This invention uses a watering tray to water the lower side of the seedlings, improving the uniformity of irrigation and reducing the differences in growth between seedlings in different positions on the same cultivation tray. The height of the watering tray is controlled by an elastic element to ensure that the water and fertilizer in the watering tray always irrigate the lower side of the seedlings.

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example 1
[0030] The horizontal hierarchical structure results in a large projected area occupied by each layer. To stably support the seedling trays, each layer's placement board must be level, and its size is usually matched to the arrangement requirements of the seedling trays, causing each layer to occupy the same area horizontally. In space-constrained seedling nurseries, this design severely limits the number of seedlings per unit area, resulting in low overall space utilization efficiency. Furthermore, to ensure uniform light exposure for seedlings on each layer, a complete cultivation light is typically required for each layer. This not only leads to high equipment purchase costs but also high operating energy consumption, resulting in high seedling costs.
[0031] A seedling rack for vegetable cultivation, such as Figures 1-9As shown, the device includes an outer casing 1, a control module 2 mounted on the outer casing 1, a chassis 3 inside the outer casing 1, and circumferentially distributed support rods 4 rotatably connected to the chassis 3. A fixed frame 5 is fixed to the support rods 4, and the fixed frame 5 has several pairs of support members 6 arranged in a circular array. Each pair of support members 6 holds a cultivation tray 7, which has evenly distributed through holes (not shown in the figure) for receiving seedlings. A cultivation lamp 8 is installed inside the outer casing 1 and is electrically connected to the control module 2. A drive mechanism is installed on the chassis 3 to rotate the support rods 4. A power mechanism is installed on the fixed frame 5 to move all the support members 6 on the same fixed frame 5. The cultivation lamp 8 is a circular lamp tube. The cultivation lamp 8 is located between all the support rods 4, and its axis coincides with the axis of the chassis 3.
[0032] The above scheme proposes a novel distribution method for the cultivation trays, changing the existing horizontal arrangement to a three-dimensional vertical distribution, which reduces the footprint of the cultivation trays. Lights are placed between all the cultivation trays, reducing the use of lamps and saving energy while ensuring adequate illumination. The control module 2 is electrically connected to all electrical components in this document, controlling the opening and closing of all electrical components. In this embodiment, the chassis 3 and the outer shell 1 are fixedly connected. The number of support rods 4 is four, as shown in the illustration. The cultivation lamp 8 is an existing circular lamp tube with no external obstruction, ensuring consistent light intensity to the surrounding area.
[0033] like Figure 2 and Figure 3 As shown, the drive mechanism includes: a first motor 201, which is fixed to the chassis 3 and electrically connected to the control module 2; a drive gear 202, which is fixed to the output shaft of the first motor 201 and is rotatably connected to the cultivation lamp 8; and a number of passive gears 203 distributed circumferentially, which are fixed to adjacent support rods 4 respectively, and the passive gears 203 mesh with the drive gears 202.
[0034] In the above scheme, a method is proposed to adjust the position of all the culture trays 7 so that the outer culture trays 7 on the same fixed frame 5 can also be illuminated by the culture lamp 8; the first motor 201 is an existing servo motor, the active gear 202 is located on the lower side of the culture lamp 8; the passive gear 203 corresponds one-to-one with the support rod 4.
[0035] like Figures 2-7 and Figure 9As shown, the power mechanism includes a second motor 301, which is a servo motor. The second motor 301 is fixed to the side wall of the fixed frame 5 and electrically connected to the control module 2. The second motor 301 drives the chain drive module 302. The chain drive module 302 is mounted on the fixed frame 5. The chain drive module 302 is a conventional chain conveyor, consisting of two chains, two pairs of upper and lower sprockets, and two upper and lower rotating shafts. The output shaft of the second motor 301 is fixedly connected to the lower rotating shaft. Rotary connecting rods are rotatably connected to the chains of the chain drive module 302. Several connecting frames 303 are arranged in a circular array. The number and distribution of connecting frames 303 are the same as those of the support members 6. The connecting frames 303 are fixedly connected to the adjacent support members 6. The fixed frame 5 is provided with symmetrically distributed guide grooves 51. The connecting frames 303 have a cross structure. The guide grooves 51 are used to guide the crosses of the adjacent connecting frames 303, so that the connecting frames 303 can move along the adjacent guide grooves 51. During the sliding process of the connecting frames 303 along the guide grooves 51, the crosses of the connecting frames 303 cannot rotate, so that the support members 6 cannot rotate, thereby ensuring that the cultivation tray 7 is always in a horizontal state.
[0036] like Figure 2 and Figure 3 As shown, it also includes: a third motor 401, fixed to the outer shell 1, the third motor 401 is a servo motor and is electrically connected to the control module 2; a drive frame 402, fixed to the output shaft of the third motor 401, the projection of the drive frame 402 on the horizontal plane is a cross structure, the fixed frame 5 and the cultivation lamp 8 are rotatably connected to the drive frame 402, the cultivation lamp 8 is located between the drive frame 402 and the drive gear 202, the chassis 3 is rotatably connected to the outer shell 1, the front side of the outer shell 1 is provided with an opening, and the outer shell 1 is provided with a shielding door at the opening. By arranging all the cultivation trays 7 vertically in three dimensions and rotating the cultivation trays 7 on the same fixed frame 5 in the vertical direction, the position of all the cultivation trays 7 is automatically adjusted, reducing the workload of placing the cultivation trays 7.
[0037] The working principle of this embodiment:
[0038] When using a seedling tray for seedling cultivation, all seedlings must first be placed into the corresponding cultivation tray 7 in sequence before the seedling cultivation work can begin.
[0039] Place seedlings:
[0040] Open the cover door of the outer shell 1, then control the third motor 401 so that the output shaft of the third motor 401 drives the drive frame 402 to rotate circumferentially. The drive frame 402 drives all the fixed frames 5 to rotate, the fixed frames 5 drive the adjacent support rods 4 to rotate, and all the support rods 4 together drive the chassis 3 to rotate. When one of the fixed frames 5 corresponds to the opening of the outer shell 1, the third motor 401 is turned off. Then the grower places the seedlings on the fixed frame 5 in sequence on all the cultivation trays 7 near the opening of the outer shell 1.
[0041] After all the cultivation trays 7 near the opening have been filled with seedlings, the second motor 301 is turned on. The output shaft of the second motor 301 controls the chain drive module 302 to move slowly. The chain drive module 302 drives all the connecting frames 303 on it to move slowly. The connecting frames 303 drive the adjacent support pieces 6 to move. Each pair of support pieces 6 together drives the adjacent cultivation trays 7 to move slowly, thereby moving the cultivation trays 7 near the opening to the inside and the cultivation trays 7 near the cultivation light 8 to the outside. During the movement of all the cultivation trays 7, the grower continues to place seedlings in the remaining cultivation trays 7. After all the cultivation trays 7 on the fixed frame 5 have been filled with seedlings, the second motor 301 is turned off and the third motor 401 is turned on again. The above operation is repeated to move the next fixed frame 5 to the opening of the outer shell 1. Then the above operation is repeated to place the seedlings into all the cultivation trays 7 on the fixed frame 5 in sequence. After multiple repetitions and all the cultivation trays 7 have been filled with seedlings, the third motor 401 is turned off.
[0042] Cultivation work:
[0043] The cultivation lamp 8 is turned on, illuminating the seedlings around it and enabling them to photosynthesize. Simultaneously, the first motor 201 is activated, and its output shaft drives the drive gear 202 to rotate slowly counter-clockwise. Figure 3 (Based on the top view), the driving gear 202 drives all the driven gears 203 to rotate slowly clockwise. The driven gears 203 drive the fixed frame 5 to rotate (rotate) through the adjacent support rod 4. The fixed frame 5 drives all the supporting parts 6 on it to rotate, thereby causing the right side of the seedling on the right side of the cultivation tray 7 on the fixed frame 5 to rotate to the side closer to the cultivation light 8 (so that...). Figure 3 (For example).
[0044] During the operation of the first motor 201, all the second motors 301 are activated, and all the chain drive modules 302 start working again, driving all the supporting parts 6 on them to move, so as to Figure 3Taking the middle part as an example, all the supporting parts 6 move vertically under the action of the adjacent chain drive module 302. After the left side of the cultivation tray 7 on the left side of the fixed frame 5 receives light, it slowly moves to the right side of the fixed frame 5. At the same time, the cultivation tray 7 on the right side of the fixed frame 5 slowly moves to the left side of the fixed frame 5, so that the left side of the cultivation tray 7 receives light.
[0045] During the operation of the first motor 201 and all the second motors 301, the cultivation lamps 8 are placed between all the cultivation trays 7 so that the seedlings on all the cultivation trays 7 can be evenly irradiated by the cultivation lamps 8.
[0046] Completed cultivation:
[0047] Turn off the cultivation light 8 and the first motor 201. Then, control the four fixed frames 5 to move sequentially to the opening of the outer shell 1 through the third motor 401. At the same time, while all the second motors 301 are working, the seedlings on each cultivation tray 7 are removed sequentially. After all the seedlings have been removed, turn off the second motor 301 and the third motor 401.
[0048] Example 2
[0049] Research has found that existing seedling trays use a spray system to irrigate seedlings in the cultivation trays. However, the spray range and intensity of the spray head are difficult to control precisely. The water-fertilizer mixture tends to accumulate on the leaves of vegetable seedlings, resulting in localized over-wetting of the leaves, which affects photosynthesis and transpiration, leading to slow seedling growth and weakened seedling vigor. Furthermore, the water-fertilizer mixture tends to concentrate on the soil surface during spraying, making it difficult to penetrate evenly to deeper layers. This results in excessive nutrients and water in the surface soil, while the deeper layers are under-supplied. At the same time, the upper leaves can block the water-fertilizer mixture, preventing the soil from evenly contacting the mixture.
[0050] Based on Example 1, such as Figure 4 and Figures 6-9 As shown, each pair of support members 6 is slidably connected to a water replenishment tray 601. The water replenishment tray 601 is filled with a certain amount of water-fertilizer mixture and is located on the lower side of the adjacent cultivation tray 7. It is used to irrigate the seedlings on the cultivation tray 7 from the lower side. The water and fertilizer act directly on the roots or the seedling substrate without spraying onto the leaves. This solves the problem of localized overwetting of the leaves and the induction of diseases caused by spraying, and ensures normal respiration and photosynthesis of the seedling leaves. Without the impact of spray water droplets, the surface of the seedling substrate can be prevented from hardening, ensuring root aeration and rooting environment.
[0051] like Figure 8 and Figure 9As shown, an elastic element 701 is fixedly connected between the support 6 and the adjacent watering tray 601. The elastic element 701 is a spring, and it is initially in a compressed state. That is, the water-fertilizer mixture inside the watering tray 601 is initially compressed by the gravity of the water-fertilizer mixture. The elastic element 701 is used to move the adjacent watering tray 601. As the amount of water-fertilizer mixture in the watering tray 601 gradually decreases, the squeezing force on the elastic element 701 gradually decreases. The elastic element 701 moves the adjacent watering tray 601 upward, so that the water-fertilizer mixture in the watering tray 601 can always irrigate the seedlings on the adjacent cultivation tray 7. The cultivation tray 7 is provided with evenly distributed water-absorbing elements 801 on its lower side. The through holes on the cultivation tray 7 correspond one-to-one with the water-absorbing elements 801 on the upper side. When the seedlings are placed on the cultivation tray 7, the seedlings pass through the corresponding through holes on the cultivation tray 7. The seedling has a through hole and contacts the corresponding water-absorbing component 801. There are two ways in which the seedling and the water-absorbing component 801 are in contact: one is that the lower side of the seedling is attached to the upper side of the corresponding water-absorbing component 801, and the other is that the upper side of the water-absorbing component 801 can be provided with blind holes, and the seedling is located in the blind holes of the corresponding water-absorbing component 801, that is, the water-absorbing component 801 wraps the lower side of the seedling. During use, the seedling is placed on the water-absorbing component 801. The number and distribution of the water-absorbing components 801 on the cultivation tray 7 are the same as those of the seedlings on the cultivation tray 7. The water-absorbing component 801 is a water-absorbing sponge, which is used to slowly and evenly transfer the water in the water replenishment tray 601 to the soil of the corresponding seedling, reducing the occurrence of water accumulation and oxygen deficiency caused by direct soaking of the soil, while maintaining appropriate soil moisture, which not only meets the water absorption needs of the seedling roots, but also ensures soil aeration and prevents root rot.
[0052] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the invention.
