Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and more specifically, to a layered seedling device. Background Technology

[0002] Seedling raising is a crucial stage in crop growth, directly impacting survival rate, growth rate, and final yield. Layered seedling raising devices, through their multi-layered design, fully utilize vertical space, significantly increasing seedling density. However, existing layered seedling raising devices suffer from several drawbacks. The upper layers of crops can shade the lower layers, resulting in insufficient sunlight. This uneven light distribution directly affects the photosynthetic efficiency of the lower-layer crops, thus slowing their growth. Furthermore, after seedling raising, workers must dig up the seedlings for replanting. This process easily damages the roots, further reducing survival rates. Utility Model Content

[0028] Please see Figure 1-5A layered seedling raising device includes a base 1, two support frames 2 fixedly mounted on the base 1, two rotating frames 3 rotatably mounted between the two support frames 2, and multiple seedling boxes 4 rotatably mounted on each rotating frame 3. The base 1 is provided with a drive groove 5, and a bidirectional lead screw 6 is rotatably mounted in the drive groove 5. A motor 7 is fixedly mounted on one side of the base 1, and the drive end of the motor 7 extends into the drive groove 5 and is fixedly connected to the bidirectional lead screw 6. Two movable seats 8 are threaded on the bidirectional lead screw 6. A push frame 9 is fixedly mounted on the upper end of each movable seat 8 through the drive groove 5. Two limit seats 10 are respectively hinged to both ends of the push frame 9. The limit seats 10 are slidably connected to the rotating frames 3. Two limit grooves 11 that cooperate with the limit seats 10 are provided on one side of the rotating frame 3. Two connecting columns 12 are fixedly mounted on the lower end of each seedling box 4, and a counterweight bar 13 is fixedly connected to the two connecting columns 12.

[0029] In this embodiment, the entire device is controlled by controller 23. Since the device matched with controller 23 is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here. When the plants that need to be cultivated are exposed to sunlight, controller 23 controls motor 7, which drives the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 is provided with two threaded areas in opposite directions, which causes the two moving seats 8 to move in the direction of separation. The moving seats 8 drive the push frame 9 to move, and the push frame 9 drives the limit seat 10 to move, so that the limit seat 10 moves along the limit groove 11 and pushes the rotating frame 3 to rotate. During the rotation of the rotating frame 3, it will drive multiple seedling boxes 4 to move, so that the multiple seedling boxes 4 are arranged in a stepped shape. Due to the action of the counterweight 13, the crops in the seedling chamber 14 are always in a vertical direction. When the entire device is not in use, it can be retracted and stored by the reverse operation.

[0030] Please see Figures 1-5 As one method of crop removal: the seedling box 4 is provided with multiple seedling chambers 14, each seedling chamber 14 is fixedly provided with a limiting ring 15, a tray 16 is movably provided on the limiting ring 15, the tray 16 is provided with a drainage hole 17, each tray 16 is fixedly provided with two pull rods 18, the seedling chamber 14 is provided with two positioning grooves 19 that cooperate with the pull rods 18, one end of each pull rod 18 passes through the positioning groove 19 and is fixedly provided with a pull ring 20, each seedling box 4 is provided with a collection chamber 21, the collection chamber 21 is connected to multiple seedling chambers 14, the collection chamber 21 is fixedly connected with a hose 22, and a controller 23 is fixedly provided on one side of the base 1.

[0031] More specifically, when raising seedlings in the seedling room 14, the tray 16 is placed on the limiting ring 15 for positioning. The required nutrient soil is placed on the tray 16 in the seedling room 14 for seedling raising. During the watering of the crops, excess water or nutrient solution will enter the collection chamber 21 through the drain hole 17. Since the hose 22 is connected to the external collection box, the excess water or nutrient solution enters the collection box through the hose 22 for collection and can be recycled. When the seedlings are finished and need to be removed, pull the two pull rings 20. The pull rings 20 drive the pull rod 18 to move along the positioning groove 19. The pull rod 18 drives the tray 16 to move, so that the tray 16 moves the crops and nutrient soil together out.

[0032] In summary, during use or operation of the entire device: the entire device is controlled by controller 23. Since the device matched with controller 23 is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here. When seedling cultivation is required, tray 16 is placed on limiting ring 15 for limiting, and the required nutrient soil is placed on tray 16 in seedling chamber 14 for seedling cultivation. During the watering of crops, excess water or nutrient solution will enter the collection chamber 21 through the drain hole 17. Since the hose 22 is connected to the external collection box, excess water or nutrient solution enters the collection box through hose 22 for collection and can be recycled. When the seedlings are finished and need to be removed, pull the two pull rings 20. The pull rings 20 drive the pull rod 18 to move along the positioning groove 19. The pull rod 18 drives the tray 16 to move, so that the tray 16 moves the crops and nutrient soil together.

[0033] When the crops need to be exposed to sunlight during the seedling stage, the controller 23 controls the motor 7, which drives the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 has two threaded areas with opposite directions, causing the two moving seats 8 to move in the opposite direction. The moving seats 8 drive the push frame 9 to move, and the push frame 9 drives the limit seat 10 to move, causing the limit seat 10 to move along the limit groove 11 and push the rotating frame 3 to rotate. During the rotation of the rotating frame 3, multiple seedling boxes 4 will move, so that the multiple seedling boxes 4 are arranged in a stepped manner. Due to the action of the counterweight 13, the crops in the seedling chamber 14 are always in a vertical direction. When the entire device is not in use, it can be retracted and stored by using the reverse operation.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
