A smart agricultural plant seedling planting rack

Abstract

This invention belongs to the field of agricultural seedling cultivation technology, specifically a smart agricultural plant seedling planting rack, including an upright frame, a support frame, a rack, a first gear, a rotating shaft, and a power component. In this invention, the power component drives one of the rotating shafts to rotate, which, through a pulley and belt, drives the first gears at both ends of another rotating shaft to rotate. This, in turn, drives the first gears inside the four uprights to rotate, thereby achieving synchronous movement of each position of the support frame. This allows for simultaneous adjustment of the frame's height, thus adjusting the planting rack's layer height. Because the support frame adjusts synchronously, it moves more stably, providing better safety when adjusting with seedling pots on it. Users only need to control the movement of the power component to adjust the planting rack's layer height, making the adjustment operation simple and easy, thus improving the practicality of the planting rack.

Description

Technical Field

[0001] This invention belongs to the field of agricultural seedling cultivation technology, specifically a smart agricultural plant seedling planting rack. Background Technology

[0002] Seedling cultivation is a crucial step in plant planting. During seedling cultivation, planting racks are typically used to hold seedling pots for unified cultivation and management. Commonly used planting racks are tiered vertically to facilitate layered storage of seedling pots and improve space utilization. However, since the growth stages and heights of seedlings vary in each pot, a fixed tiered planting rack often results in inconsistent layer heights. Insufficient height hinders seedling growth, while excessive height wastes space. Both outcomes reduce the practicality of the planting rack. Therefore, a planting rack with adjustable tier height is needed. However, most methods involve removing the tiers, adjusting their positions, and then reinstalling them, leading to cumbersome and difficult-to-operate adjustments. Summary of the Invention

[0011] Preferably, sealing plates are symmetrically arranged on both sides of the upright frame; the sealing plates are fixedly connected to the upright frame.

[0012] The beneficial effects of this invention are as follows: 1. In this invention, the movement of a power component causes one of the rotating shafts to rotate, which in turn causes the first gears at both ends of the shaft to rotate, thus moving the gears relative to the rack and achieving vertical movement. The rotation of one shaft, through the transmission of pulleys and belts, causes the second gear to rotate, which in turn drives the third gear to rotate. This motion is then transmitted to another rotating shaft through another set of pulleys and belts, causing the first gears at both ends of that shaft to rotate. This, in turn, through the operation of the power component, drives the first gears inside the four columns to rotate. The transmission between the second and third gears ensures that the first gears on the two rotating shafts rotate in opposite directions. With the meshing position of the rack and pinion reversed, when the power component drives one of the rotating shafts to rotate, the first gears in all four columns move in the same vertical direction, thus achieving synchronous movement of all positions on the support frame. This allows for adjustment of the height of the support frame and, consequently, the height of the planting rack layers. Because the support frame adjusts synchronously, it moves more smoothly, providing better safety when adjusting with seedling trays on it. Furthermore, since the user only needs to control the movement of the power component to adjust the height of the planting rack layers, the adjustment operation is simple and easy to perform, thereby improving the practicality of the planting rack.

[0013] 2. In this invention, a worm gear is installed on one side of the support frame, followed by a bracket at the lower part of the support plate, and a turbine at the lower part of the bracket. The force of the worm gear is then transmitted to the rotating shaft via gears four and five. This satisfies the installation space requirements of the worm gear, facilitating the installation of the power components. During operation, the user rotates the handle, causing the worm gear to rotate, which in turn drives the turbine, which in turn drives gear four, which in turn drives gear five, ultimately rotating the rotating shaft. This allows for the vertical adjustment of the support frame. Since the user only needs to rotate the handle during adjustment, operation is simple and the position of the support frame can be controlled more accurately. Furthermore, because the worm gear has a self-locking characteristic, no additional locking is required after adjustment, further simplifying the adjustment process and improving the practicality of the planting frame.

[0014] 3. In this invention, the rotating handle is positioned on the front of the planting rack for ease of operation. However, this can obstruct the user when placing seedling pots, resulting in a poor user experience and an unsightly outer frame. Therefore, in this solution, the rotating handle is designed as a rotating plate and a handrail. During use, rotating the handrail makes it perpendicular to the rotating plate, facilitating rotation. When not in use, rotating the handrail keeps it flush with the rotating plate, allowing it to rest against the side wall of the support frame. This reduces the thickness of the protruding handle, minimizing obstruction when placing seedling pots and improving user comfort. Furthermore, a compression spring between the rotating plate and the handrail keeps them in a stretched state, preventing easy rotation of the handrail and ensuring the handle remains stably flush with the support frame when not in use, resulting in a more aesthetically pleasing planting rack.

[0015] 4. In this invention, the height of each layer of the planting rack is adjusted to be close to the height of the plant seedlings. This makes it difficult to lift the seedling pots directly when removing them, as the pots are essentially flush with the seedlings. Therefore, a sliding plate is provided on the upper part of the support frame. When placing the seedling pots, they are placed on the sliding plate. When removing the pots, the sliding plate is pulled to move the pots between the two support frames, making it easier for the user to remove them. This improves the ease of removing the seedling pots and enhances the usability of the planting rack.

[0016] 5. In this invention, when the seedling tray is removed, the sliding plate extends outward, causing the center of gravity of the planting frame to shift forward, which may lead to the risk of the planting frame tipping over and reduce its safety. Therefore, in this solution, during use, the user steps on one end of the pedal, causing the pedal to deflect, which in turn causes the other end of the pedal to deflect, thus pressing the piston rod of the first hydraulic cylinder. This causes the piston rod of the first hydraulic cylinder to press inward, causing the medium inside the first hydraulic cylinder to move into the second hydraulic cylinder. This causes the movable rod of the second hydraulic cylinder to extend outward, pushing the moving frame outward. This causes the bottom of the planting frame to spread, thus changing the fulcrum for the planting frame to flip. As a result, after the sliding plate moves outward, the center of gravity of the planting frame is still behind the fulcrum, effectively preventing the planting frame from tipping over. This design improves the safety of the plant stand. Furthermore, by making the cross-section of hydraulic cylinder number one larger than that of hydraulic cylinder number two, the movable rod of hydraulic cylinder number two can extend more when the piston rod of hydraulic cylinder number one moves only a small amount. This allows for rapid extension of the mobile stand and reduces the displacement caused by the user's footing, making the support operation of the mobile stand easier and improving the user's comfort. After removing the seedling pots, when the user releases their foot from the pedal, the piston rod of hydraulic cylinder number one extends under the action of the return spring, causing the movable rod of hydraulic cylinder number two to retract. This moves the mobile stand inwards, preventing it from obstructing the user's movement and further improving the safety of the plant stand. It also eliminates the need for further user intervention, thus enhancing the ease of use of the plant stand. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 10 As shown, a smart agricultural plant seedling planting rack includes a frame 1, a support frame 2, a rack 3, a first gear 4, a support wheel 5, a mounting frame 6, a rotating shaft 7, a second gear 8, a third gear 9, and a power component; the frame 1 includes symmetrically arranged columns; the columns are provided with sliding grooves; a rack 3 is provided on one side of the sliding groove; the rack 3 is fixedly connected to the columns; A mounting bracket 6 is provided inside the slide groove; a rotating shaft 7 is provided on one side of the mounting bracket 6; the rotating shaft 7 is rotatably connected to the mounting bracket 6; a gear is provided on one side of the mounting bracket 6; the gear is fixedly connected to the rotating shaft 7; the gear meshes with the rack 3; support wheels 5 are symmetrically arranged on the other side of the mounting bracket 6; the support wheels 5 are rotatably connected to the mounting bracket 6; the support wheels 5 abut against the side wall of the slide groove. The support frames 2 are spaced apart between the uprights 1; the rotating shafts 7 are symmetrically arranged at the lower part of the support frames 2; the support frames 2 are rotatably connected to the rotating shafts 7; the second gear 8 and the third gear 9 are arranged on the support frames 2 between the rotating shafts 7; the second gear 8 and the third gear 9 are both rotatably connected to the support frames 2 by pins; the second gear 8 and the third gear 9 mesh; the second gear 8 is connected to one of the rotating shafts 7 by a pulley and a belt; the third gear 9 is connected to the other rotating shaft 7 by a pulley and a belt. The power component is provided on one side of the support frame 2; the power component is used to drive the rotating shaft 7 to rotate; the power component is capable of self-locking.

[0021] During operation, when the planting rack needs to be repositioned, the movement of the power components causes one of the rotating shafts to rotate. This, in turn, causes the first gear 4 at both ends of the rotating shaft 7 to rotate, which in turn moves relative to the rack 3, thus achieving vertical movement. The rotation of one rotating shaft 7, through the transmission of pulleys and belts, causes the second gear 8 to rotate, which in turn drives the third gear 9 to rotate. This motion is then transmitted to another rotating shaft 7 through another set of pulleys and belts, causing the first gear 4 at both ends of this rotating shaft 7 to rotate. This, in turn, through the operation of the power components, drives the first gear 4 inside each of the four uprights to rotate. The transmission of the second gear 8 and the third gear 9 further drives the movement of the two rotating shafts 7. The first gear 4 rotates in the opposite direction. Because the meshing position of the rack 3 is opposite, when the power component drives one of the rotating shafts 7 to rotate, the first gear 4 in each of the four columns moves in the same direction in the vertical direction. This allows the support frame 2 to move synchronously, thereby adjusting the height of the support frame and the height of the planting rack. Because the support frame 2 is adjusted synchronously, it moves more smoothly and is safer during adjustment. At the same time, since the user only needs to control the movement of the power component to adjust the height of the planting rack, the adjustment operation is simple and easy to operate, thus improving the practicality of the planting rack.

[0022] like Figures 3 to 5 As shown, the power component includes a turbine 10, a worm gear 11, a bracket 12, a fourth gear 13, a fifth gear 14, and a rotating handle. The worm gear 11 is located on one side of the support frame 2; the worm gear 11 is rotatably connected to the support frame 2; the turbine 10 is located at the lower part of the worm gear 11; the bracket 12 is located at the lower part of the support frame 2; the bracket 12 is fixedly connected to the support frame 2; the turbine 10 is rotatably connected to the bracket 12 via a rotating shaft; the turbine 10 is fixedly connected to the rotating shaft; the fourth gear 13 is located on the rotating shaft; the fourth gear 13 is fixedly connected to the rotating shaft; the fifth gear 14 is located on one of the rotating shafts 7; the fifth gear 14 is fixedly connected to the rotating shaft 7; the fourth gear 13 meshes with the fifth gear 14; a rotating handle is located at one end of the worm gear 11; the rotating handle is fixedly connected to the worm gear 11.

[0023] In operation, the partitions used for separation in planting racks are usually not very thick to improve space utilization. Similarly, in this design, the support frame 2 is not very thick. Therefore, the power components must be able to directly act on the rotating shaft 7, and the installation space must be fully considered. Thus, in this design, a worm gear 11 is installed on one side of the support frame 2, followed by a bracket 12 at the bottom of the support plate, and a turbine 10 at the bottom of the bracket 12. The force of the turbine 10 and worm gear 11 is then transmitted to the rotating shaft 7 via gears 13 and 14. This satisfies the installation space requirements for the turbine 10 and worm gear 11, thereby facilitating... Regarding the power components, during operation, the user rotates the handle, causing the worm gear 11 to rotate, which in turn drives the turbine 10 to rotate, which in turn drives the fourth gear 13 to rotate, which in turn drives the fifth gear 14 to rotate, thereby causing the rotating shaft 7 to rotate. This allows for the vertical adjustment of the support frame 2. Since the user only needs to rotate the handle during adjustment, the operation is simple and the position of the support frame 2 can be controlled more accurately. At the same time, because the turbine 10 and worm gear 11 have self-locking characteristics, no additional locking is required after adjustment, making the adjustment process simpler and more convenient, thus improving the practicality of the planting rack.

[0024] like Figures 4 to 6 As shown, the rotating handle includes a rotating plate 15, a handrail plate 16, and a compression spring 17; the rotating plate 15 is fixedly connected to the worm gear 11; the handrail plate 16 is provided at one end of the rotating plate 15; the handrail plate 16 is rotatably connected to the rotating plate 15; the handrail plate 16 rotates along the thickness direction of the rotating plate 15; a compression spring 17 is provided between the rotating plate 15 and the handrail plate 16; one end of the compression spring 17 abuts against the rotating plate 15; the other end of the compression spring 17 abuts against the end of the handrail plate 16.

[0025] In operation, the rotating handle is positioned on the front of the planting rack for ease of use. However, this can obstruct the user when placing seedling pots, resulting in a poor user experience and an unsightly appearance of the rack's outer frame. Therefore, in this solution, the rotating handle is configured as a rotating plate 15 and a handrail plate 16. During use, rotating the handrail plate 16 makes it perpendicular to the rotating plate 15, facilitating rotation. When not in use, rotating the handrail plate 16 keeps it and the rotating plate 15 on the same plane. This design allows the rotating handle to fit snugly against the side wall of the support frame 2, reducing the thickness of the protruding handle and minimizing obstruction when placing seedling pots, thus improving the comfort of using the planting rack. Simultaneously, by installing a compression spring 17 between the rotating plate 15 and the handrail plate 16, the rotating plate 15 and the handrail plate 16 are kept in a pulled state, preventing the handrail plate 16 from rotating easily. This ensures that the rotating handle remains stably fitted against the support frame 2 when not in use, resulting in a more aesthetically pleasing planting rack.

[0026] like Figure 8 As shown, a sliding plate 18 is provided on the upper part of the support frame 2; the sliding plate 18 is slidably connected to the support frame 2 via a slide rail.

[0027] During operation, since the height of the planting racks in this design is adjusted to be close to the height of the plant seedlings, the mounting rack 6 is basically in close contact with the plant seedlings. Therefore, when removing the seedling pots, it is difficult to lift the seedling pots a certain distance and remove them, making it difficult to remove the seedling pots. Therefore, by setting a sliding plate 18 on the upper part of the support frame 2, the seedling pots are placed on the sliding plate 18 when placing them. When removing the seedling pots, by pulling the sliding plate 18, the seedling pots can be moved horizontally between the two support frames 2 by the support 12, making it easier for the user to remove the seedling pots. This improves the convenience of removing the seedling pots and the ease of use of the planting rack.

[0028] like Figure 7 and Figure 8 As shown, a sliding frame 19 is symmetrically arranged at the lower part of the upright frame 1; the sliding frame 19 is fixedly connected to the upright frame 1; a movable frame 20 is arranged at the lower part of the upright frame 1; the movable frame 20 is slidably connected to the sliding frame 19; a sliding wheel is symmetrically arranged on one side of the movable frame 20; the sliding wheel is fixedly connected to the movable frame 20. A foot pedal 25 is provided at the lower part of the support frame 1; the middle part of the foot pedal 25 is hinged to the support frame 1; a first hydraulic cylinder 21 is provided at one end of the foot pedal 25; the first hydraulic cylinder 21 is fixedly connected to the support frame 1; one end of the foot pedal 25 abuts against one end of the piston rod of the first hydraulic cylinder 21; a return spring is provided at the end of the first hydraulic cylinder 21 away from the piston rod; one end of the return spring abuts against the cylinder body; the other end of the return spring abuts against one end of the piston rod. A second hydraulic cylinder 22 is installed at the lower part of the support frame 1; the second hydraulic cylinder 22 is fixedly connected to the support frame 1; the end of the cylinder body of the second hydraulic cylinder 22 away from the movable rod is connected to the end of the cylinder body of the first hydraulic cylinder 21 away from the piston rod through a hose; the cross-sectional area of ​​the cylinder body of the first hydraulic cylinder 21 is larger than the cross-sectional area of ​​the cylinder body of the second hydraulic cylinder 22; one end of the movable rod of the second hydraulic cylinder 22 is fixedly connected to the movable frame 20.

[0029] During operation, when the seedling tray is removed, the sliding plate 18 extends outward, causing the center of gravity of the planting rack to shift forward, which may lead to the risk of the planting rack tipping over and reduce its safety. Therefore, in this solution, the user steps on one end of the pedal 25, causing the pedal to deflect. This deflects the other end of the pedal 25, which in turn presses the piston rod of the first hydraulic cylinder 21. This causes the piston rod of the first hydraulic cylinder 21 to press inward, which in turn causes the medium inside the first hydraulic cylinder 21 to move into the second hydraulic cylinder 22. This causes the movable rod of the second hydraulic cylinder 22 to extend outward, pushing the moving frame 20 outward. This causes the bottom of the planting rack to spread, thus changing the fulcrum for the planting rack to flip. As a result, after the sliding plate 18 moves outward, the center of gravity of the planting rack is still behind the fulcrum, effectively preventing the planting rack from tipping over. This design improves the safety of the plant stand. Furthermore, by making the cross-section of hydraulic cylinder 21 larger than that of hydraulic cylinder 22, the movable rod of hydraulic cylinder 22 can extend more when the piston rod of hydraulic cylinder 21 moves only a small amount. This allows for the rapid extension of the movable frame 20, reducing the displacement caused by the user's foot and making the support operation of the movable frame 20 easier, thus improving the comfort of using the plant stand. After removing the seedling pot, when the user releases their foot from pedal 25, the piston rod of hydraulic cylinder 21 extends under the action of the return spring, causing the movable rod of hydraulic cylinder 22 to retract. This allows the movable frame 20 to move inwards, preventing it from obstructing the user's movement and further improving the safety of the plant stand. This design also eliminates the need for further user intervention, thus enhancing the ease of use of the plant stand.

[0030] like Figure 9 As shown, a limiting protrusion 24 is provided on one side of the sliding plate 18; the limiting protrusion 24 is fixedly connected to the sliding plate 18; a lever 23 is provided on the upper part of the movable frame 20; one end of the lever 23 is fixedly connected to the movable frame 20; the lever 23 is located on the side of the movable frame 20 near the power component.

[0031] During operation, the sliding plate 18 remains extended after the seedling tray is removed, requiring manual repositioning by the user, which makes the planting rack inconvenient to use. Therefore, in this solution, a limiting protrusion 24 is provided on the side wall of the sliding plate 18, and a lever 23 is provided on the movable frame 20. After the seedling tray is removed, the user releases the foot pedal 25, causing the movable lever to retract inward, which in turn causes the lever 23 to move inward. The lever 23 then contacts the limiting block, pushing the limiting block inward, which in turn moves the sliding plate 18 inward, thus repositioning the sliding plate 18. After the seedling tray is removed, the user no longer needs to reposition the sliding plate 18, thereby improving the ease of use of the planting rack.

[0032] like Figure 10 As shown, a slider 26 is provided at the upper end of the lever 23; the slider 26 is fixedly connected to the lever 23; a slide rail 27 is provided on one side of the lever 23; the slide rail 27 is fixedly connected to the column on the support frame 1; and the slider 26 is slidably connected to the slide rail 27.

[0033] During operation, the height of the planting frame results in a longer lever 23, leading to a longer cantilever. This causes significant deformation of the lever 23 when moving the sliding plate 18. Over time, this can cause the lever 23 to bend, preventing it from properly resetting the sliding plate 18. Therefore, this solution incorporates a slider 26 on the upper part of the lever 23 and a slide rail 27 on the upright frame 1. The slide rail and slide rail 27 work together to support the lever 23 during use, maintaining its stability and preventing excessive deformation. This improves the lifespan of the lever 23 and, consequently, the lifespan of the planting frame.

[0034] like Figures 1 to 3 As shown, sealing plates 28 are symmetrically arranged on both sides of the upright frame 1; the sealing plates 28 are fixedly connected to the upright frame 1.

[0035] During operation, by setting sealing plates 28 on both sides of the upright 1, the stability of the upright 1 can be improved, thereby improving the stability of the planting rack. At the same time, the sealing plates 28 can prevent dust and debris from entering the interior of the planting rack, thereby maintaining the cleanliness of the interior of the planting rack and improving the cleanliness of the plant rack.

[0036] During operation, when the planting rack needs to be adjusted, the movement of the power unit causes one of the rotating shafts to rotate, which in turn causes the first gear 4 at both ends of the rotating shaft 7 to rotate. This causes the gears to move relative to the rack 3, thus achieving vertical movement. The rotation of one rotating shaft 7, through the transmission of pulleys and belts, causes the second gear 8 to rotate, which in turn drives the third gear 9 to rotate. This motion is then transmitted to another rotating shaft 7 through another set of pulleys and belts, which in turn drives the first gear 4 at both ends of that rotating shaft 7. This, in turn, causes the first gear 4 inside each of the four uprights to rotate, with the second gear 8 and the third gear 9... The transmission causes the first gears 4 on the two rotating shafts 7 to rotate in opposite directions. Because the meshing positions of the racks 3 are opposite, when the power component drives one of the rotating shafts 7 to rotate, the first gears 4 in all four columns move in the same vertical direction, thus achieving synchronous movement of all positions on the support frame 2. This allows for adjustment of the height of the support frame, and consequently, adjustment of the planting shelf height. Because the support frame 2 adjusts synchronously, its movement is more stable, resulting in better safety during adjustments. Furthermore, during adjustment, the user only needs to control the movement of the power component to adjust the planting shelf height. This simplifies the adjustment process and improves the practicality of the planting rack. In planting racks, partitions are typically not very thick to maximize space utilization. Similarly, in this design, the support frame 2 is not very thick. Therefore, the power components must be able to directly act on the rotating shaft 7, and the installation space must be fully considered. Thus, in this design, a worm gear 11 is installed on one side of the support frame 2, followed by a bracket 12 at the bottom of the support plate, and a turbine 10 at the bottom of the bracket 12. The force of the turbine 10 and worm gear 11 is then transmitted to the rotating shaft 7 via gears 9 and 14. This allows the turbine 10 and worm gear 11 to achieve their intended function. The installation space requirement facilitates the installation of power components. During operation, the user rotates the handle, causing the worm gear 11 to rotate, which in turn drives the turbine 10 to rotate, which in turn drives the third gear 9 to rotate, which in turn drives the fifth gear 14 to rotate, thereby rotating the shaft 7. This allows for the vertical adjustment of the support frame 2. Since the user only needs to rotate the handle during adjustment, the operation is simple and the position of the support frame 2 can be controlled more accurately. At the same time, because the turbine 10 and worm gear 11 have a self-locking characteristic, no additional locking is required after adjustment, making the adjustment process simpler and more convenient, thus improving the practicality of the planting rack.
