Description

Technical Field

[0001] This utility model relates to the field of seedling equipment technology, and in particular to a seedling device. Background Technology

[0002] Tobacco is a warm-season crop and is quite sensitive to temperature. Different temperature conditions have a significant impact on the quality and yield of tobacco, therefore, tobacco cultivation requires relatively high standards. Tobacco seeds are small, and the growing process is easily affected by environmental factors such as temperature and humidity, which can lead to quality problems. Therefore, seedling cultivation is necessary before planting to improve the germination and emergence rates of tobacco seeds, laying a good foundation for subsequent transplanting. During seedling cultivation, growers need to control suitable temperature, humidity, and light levels to ensure the quality and health of the tobacco seedlings.

[0003] Tobacco seedlings are typically raised on seedling racks and transplanted after reaching a certain height. However, as the seedlings grow, the stacked seedling racks cause some seedlings to shade each other, resulting in insufficient sunlight for some and uneven seedling height. This, in turn, affects subsequent transplanting. Therefore, a seedling raising device is urgently needed to solve these problems. Utility Model Content

[0040] The following is combined Figures 1-4 The technical solution of the present invention will be further illustrated through specific embodiments.

[0041] In order to ensure that tobacco seedlings receive sufficient light during the seedling cultivation process, this embodiment of the invention provides a seedling cultivation device, which includes a seedling frame 1, seedling components 2, and a light-emitting component. Multiple sets of seedling components 2 are arranged vertically at intervals on the seedling frame 1. Each set of seedling components 2 includes a support member 21 and a seedling tray 22. The position of the support member 21 is adjustable both vertically and horizontally. The seedling tray 22 is mounted on the support member 21. The light-emitting component is mounted on the seedling frame 1 and is used to provide light to the seedling tray 22.

[0042] In detail, multiple seedling trays 22 containing tobacco seedlings are placed one-to-one on multiple support members 21, and the position of each support member 21 is adjusted vertically so that the seedling trays 22 are spaced apart along the height of the seedling rack 1. Then, the position of each support member 21 is adjusted along the first horizontal direction, and adjacent seedling trays 22 are adjusted in opposite directions to increase the distance between adjacent seedling trays 22 on the same side, reducing shading between tobacco seedlings and ensuring that the tobacco seedlings on the seedling trays 22 receive sufficient light, thus ensuring normal growth. As the tobacco seedlings grow, the position of the support members 21 can be adjusted vertically at any time to ensure that the tobacco seedlings receive sufficient light throughout their growth process. The number of seedling components 2 is not specifically limited here; it can be set according to actual cultivation needs.

[0043] To ensure the seedling tray 22 is stably placed on the support member 21 when its position is adjusted, the seedling device also includes a fastening assembly 6, which secures the seedling tray 22 to the support member 21. Furthermore, the support member 21 has a threaded hole. The fastening assembly 6 includes a screw 62 and an abutment 63. The screw 62 is screwed into the threaded hole, and the abutment 63 is located at one end of the screw 62, with both ends abutting against the support member 21 and the seedling tray 22, respectively. By securing the seedling tray 22 to the support member 21 using the fastening assembly 6, the device prevents the seedling tray 22 from shaking during movement on the support member 21, thus avoiding damage to the tobacco seedlings.

[0044] Specifically, refer to Figure 2 In this embodiment, the support member 21 includes a support portion 211 and two connecting portions 212. The two connecting portions 212 are located at both ends of the support portion 211. The connecting portions 212 are L-shaped, and the L-shaped openings on the two connecting portions 212 are opposite to each other. A threaded hole is located at the end of the connecting portion 212 away from the support portion 211. The seedling tray 22 is placed on the support portion 211. The seedling tray 22 includes a seedling tray body and two extensions. The two extensions are located at both ends of the seedling tray body, and the height of the two extensions is lower than the height of the seedling tray body. The two extensions can be inserted into the two L-shaped openings respectively. After the seedling tray 22 is inserted into the support member 21, the screw 62 is inserted into the threaded hole. The end of the screw 62 near the seedling tray 22 is connected to the abutment member 63. Rotating the screw 62 causes the abutment member 63 to abut against the side wall of the seedling tray body and the side wall of the connecting portion 212 respectively, and the screw 62 is screwed into the threaded hole, thereby completing the fixation of the seedling tray 22. This feature facilitates the installation and removal of the seedling tray 22.

[0045] Optionally, a rotating part 61 is provided at the end of the screw 62 away from the abutment 63. The screw 62 is rotated by the rotating part 61, which facilitates the fixing of the seedling tray 22.

[0046] In this embodiment, each seedling tray 22 is fixed by two sets of fastening components 6. Correspondingly, the support member 21 is provided with two threaded holes, and each connecting part 212 is provided with one threaded hole. This arrangement ensures that the seedling tray 22 is subjected to uniform force at both ends, thereby making the seedling tray 22 stably placed on the support member 21.

[0047] The seedling assembly 2 also includes a first connector 23 and a second connector 24. The first connector 23 is slidably mounted on the seedling rack 1 in a vertical direction, and the second connector 24 is connected to the first connector 23. The support member 21 is slidably mounted on the second connector 24 in a first horizontal direction. The first connector 23 drives the support member 21 to move in a vertical direction through the second connector 24, thereby adjusting the height of the support member 21. The support member 21 can slide in the first horizontal direction, thus allowing adjacent support members 21 to be staggered.

[0048] Furthermore, such as Figure 2 and Figure 4 As shown, the seedling rack 1 is equipped with a rack and pinion guide pair, which includes a rack 11 and a guide rail 12. The guide rail 12 is mounted on the seedling rack 1, and the rack 11 is mounted on the guide rail 12, extending vertically. The seedling device also includes multiple first drive mechanisms, which correspond one-to-one with multiple seedling components 2. Each first drive mechanism includes a first drive member 41 and a gear 42. The gear 42 is mounted inside the first connecting member 23 and meshes with the rack 11. The first drive member 41 drives the gear 42 to move along the extension direction of the rack 11, thereby driving the first connecting member 23 to move vertically. Specifically, the guide rail 12 is fixedly mounted on the side of the seedling rack 1, the rack 11 is mounted on the guide rail 12, and the rack 11 extends along the height direction of the seedling rack 1. The first connecting member 23 is located on one side of the guide rail 12. The first driving component 41 is fixed to the first connecting component 23. The first driving component 41 is connected to the gear 42 via a transmission shaft. The gear 42 is located inside the first connecting component 23. The first driving component 41 drives the gear 42 to move along the extension direction of the rack 11. The gear 42 drives the first connecting component 23 to move in the vertical direction, which in turn drives the support component 21 to slide along the height direction of the seedling rack 1, thereby adjusting the seedling tray 22 to a suitable height. By adopting the gear and rack transmission method, the seedling tray 22 can be adjusted to any height. As the tobacco seedlings grow, the spacing between adjacent seedling trays 22 can be adjusted at any time, which is more conducive to the growth of tobacco seedlings. At the same time, the gear and rack transmission method has a simple structure, stable and reliable transmission, and can reduce the shaking of the seedling tray 22 during movement.

[0049] Optionally, the seedling rack 1 is also provided with a limiting member 13, which is located at the top of the guide rail 12. The limiting member 13 is configured to limit the movement of the first connecting member 23 when it moves vertically. In this embodiment, the limiting member 13 is located at one end of the guide rail 12 and near the top of the guide rail 12. When the height of the seedling tray 22 is adjusted vertically, the limiting member 13 can limit the height of movement of the uppermost seedling tray 22, preventing the seedling tray 22 from colliding with the light-emitting component and causing damage to the seedling device.

[0050] Furthermore, the seedling raising device also includes multiple second drive mechanisms, which are arranged one-to-one with multiple seedling raising components 2. Each second drive mechanism includes a second drive member 51, a lead screw 52, ​​and a slider 53. The lead screw 52 extends along the first horizontal direction and passes through the second connector 24. The lead screw 52 is threadedly connected to the slider 53. The support member 21 is connected to the slider 53. The second drive member 51 is used to drive the lead screw 52 to rotate, so as to push the slider 53 to drive the support member 21 to move along the first horizontal direction. In detail, the second driving member 51 is connected to the lead screw 52, ​​which passes through the second connecting member 24. The slider 53 is also located within the second connecting member 24. The support member 21 is fixedly connected to the slider 53. The second driving member 51 drives the lead screw 52 to rotate, thereby pushing the slider 53 to move along the extension direction of the lead screw 52. The slider 53 drives the support member 21 to move along the first horizontal direction, thereby adjusting the position of the seedling rack 1 along the first horizontal direction. This allows adjacent seedling racks 1 to be staggered, ensuring that the tobacco seedlings receive sufficient light and guaranteeing their normal growth. It should be noted that in this embodiment, the first horizontal direction is consistent with the extension direction of the lead screw 52.

[0051] Optionally, the second connector 24 has an open receiving cavity, and the lead screw 52 is disposed on two opposite side walls of the receiving cavity. The opening faces the support member 21 and extends along a first horizontal direction. The slider 53 slides within the opening. The opening limits the range of movement of the slider 53 on the second connector 24, preventing the seedling tray 22 from falling off due to the slider 53 moving out of the second connector 24.

[0052] Optionally, both the first driving component 41 and the second driving component 51 are motors.

[0053] In some other embodiments, each group of seedling components 2 is provided with two first driving mechanisms and two second driving mechanisms. The two first driving mechanisms are respectively located on both sides of the support member 21. The two first driving mechanisms work simultaneously to adjust the position of the seedling tray 22 along the first horizontal direction. The two second driving mechanisms are respectively located on both sides of the support member 21. Correspondingly, a guide rail 12 is provided on both sides of the seedling rack 1. The two second driving mechanisms work simultaneously to adjust the position of the seedling tray 22 along the vertical direction.

[0054] Furthermore, such as Figure 1 and Figure 3As shown, the lighting assembly includes a lighting frame 31 and multiple first lighting elements 32. The lighting frame 31 is located at the top of the seedling rack 1. One end of each of the multiple first lighting elements 32 is positioned on the side of the lighting frame 31 near the seedling rack 1, and the multiple first lighting elements 32 are spaced apart around the circumference of the seedling rack 1. Specifically, the lighting frame 31 includes a first support arm 311 and two second support arms 312. The two second support arms 312 are located at both ends of the first support arm 311, and the first support arm 311 and the two second support arms 312 are arranged in an H-shape. Both second support arms 312 are located at the top of the seedling rack 1. The multiple first lighting elements 32 are spaced apart around the circumference of the seedling rack 1. One end of each first lighting element 32 is positioned on the side of the second support arm 312 near the seedling rack 1, and the other end extends towards the bottom of the seedling rack 1. The multiple first lighting elements 32 illuminate the tobacco seedlings, ensuring their normal growth.

[0055] In this embodiment, four first light-emitting elements 32 are provided, and the two ends of the two second support arms 312 extend out of both sides of the seedling rack 1. Each end of the second support arm 312 is provided with a first light-emitting element 32, so that the tobacco seedlings on the seedling tray 22 receive uniform light, thereby improving the uniformity of the growth height of the tobacco seedlings.

[0056] Furthermore, the lighting assembly also includes a second lighting element 33, which is disposed on the side of the lighting frame 31 near the seedling frame 1. The second lighting element 33 is used to illuminate the area above the seedling tray 22. By setting the second lighting element 33 to illuminate the area above the tobacco seedlings, sufficient light is ensured for the area above the tobacco seedlings.
