Description

Technical Field

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

[0002] Forest resources are a vital foundation for maintaining ecological balance and promoting sustainable development, and the cultivation of forest seedlings is a crucial link in afforestation and greening. During seedling cultivation, it is typically necessary to use cultivation racks supplemented with artificial lighting to simulate a suitable growth environment and promote healthy seedling growth. Existing cultivation equipment generally includes cultivation racks, cultivation trays placed on the racks, and lighting fixtures to provide illumination for the seedlings. The growth needs of the seedlings are met through artificial control of light, temperature, and other conditions.

[0003] However, existing cultivation devices still have some shortcomings in practical applications. Firstly, the lamps are usually fixed in position, making it impossible to flexibly adjust the light intensity according to the actual needs of seedlings at different growth stages. Excessive or insufficient light can affect seedling growth, and the fixed lighting distance limits the means of adjusting light intensity, often requiring control of lamp switching duration or replacement with lamps of different wattages, which is inconvenient and has limited effectiveness. Secondly, the connection between the cultivation trays and the cultivation racks is mostly simple placement or fixed connection, making it difficult to remove them from the device for thorough cleaning, disinfection, or transplanting of seedlings. Long-term use can easily lead to bacterial growth, affecting the hygiene of the cultivation environment and also causing inconvenience for daily maintenance. Utility Model Content

[0004] This invention provides a forest seedling cultivation device that allows for flexible adjustment of light intensity and facilitates the placement and removal of cultivation trays.

[0005] The technical solution adopted by this utility model is as follows: a forest seedling cultivation device, including a cultivation rack, with a base plate fixedly connected to the bottom of both ends of the cultivation rack, a motor fixedly installed at the top inside the cultivation rack, a bidirectional lead screw provided at the output end of the motor, two symmetrically arranged lead screw sleeves threaded onto the bidirectional lead screw, two connecting seats one fixedly connected to the bottom of each of the two lead screw sleeves, a lamp holder slidably connected below the bidirectional lead screw inside the cultivation rack, two symmetrically arranged connecting seats two fixedly installed on the top of the lamp holder, the connecting seats one and connecting seats two on the same side being connected by a connecting rod, a fluorescent lamp installed at the bottom of the lamp holder, and two sliding seats provided below the lamp holder on the inner side wall of the cultivation rack, with a cultivation tray slidably connected between the two sliding seats.

[0006] As a further improvement of this utility model, a bearing seat is fixedly installed at the top of the cultivation rack, and the end of the bidirectional lead screw away from the motor is connected to the bearing seat.

[0007] As a further improvement of this utility model, the top of each of the two lead screw sleeves is fixedly connected to a limiting slider, and the top wall of the cultivation rack is provided with a limiting groove for the limiting slider to slide.

[0008] As a further improvement of this utility model, both ends of the connecting rod are hinged to connecting seat one and connecting seat two respectively via rotating shafts.

[0009] As a further improvement of this utility model, both sides of the lamp holder are fixedly connected with guide sliders that pass through the side wall of the cultivation rack, and both sides of the cultivation rack are provided with guide grooves for the guide sliders to pass through and slide.

[0010] As a further improvement of this utility model, both sides of the cultivation tray are fixedly connected with sliding blocks that are slidably connected to the sliding seat. The rear end of the sliding seat is a closed structure and the front end of the sliding seat is provided with a limiting mechanism that cooperates with the sliding blocks.

[0011] As a further improvement of this utility model, the limiting mechanism includes a movable block disposed above the sliding seat, a limiting post that passes through the top wall of the sliding seat and cooperates with the sliding block is fixedly connected to the bottom of the movable block, the movable block and the sliding seat are connected by a spring sleeved on the outside of the limiting post, and a pull ring is fixedly connected to the top of the movable block.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a motor to drive a bidirectional lead screw to rotate, causing the lead screw sleeve to move in opposite directions. This, in turn, pushes or pulls the lamp holder to rise and fall smoothly through the hinged connecting rod, achieving stepless adjustment of the distance between the fluorescent lamp and the cultivation tray. This effectively meets the differentiated light intensity requirements of seedlings at different growth stages. At the same time, the cultivation tray, through the cooperation of the sliding connection and the limiting mechanism, enables convenient pushing and pulling for placement and removal, greatly facilitating the cleaning, disinfection, and seedling transplanting of the cultivation tray, and significantly improving the convenience of use and cultivation efficiency.

[0015] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0016] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] This utility model provides the following: Figure 1-5 The illustrated forest seedling cultivation device includes a cultivation rack 1. Base plates 2 are fixedly connected to the bottom of both ends of the cultivation rack 1. A motor 3 is fixedly installed at the top inside the cultivation rack 1. A bidirectional lead screw 4 is provided at the output end of the motor 3. Two symmetrically arranged lead screw sleeves 5 are threaded onto the bidirectional lead screw 4. Two connecting seats 6 are fixedly connected to the bottom of each of the two lead screw sleeves 5. A lamp holder 7 is slidably connected below the bidirectional lead screw 4 inside the cultivation rack 1. Two symmetrically arranged connecting seats 8 are fixedly installed on the top of the lamp holder 7. Connecting seats 6 and 8 on the same side are connected by a connecting rod 9. A fluorescent lamp 10 is installed at the bottom of the lamp holder 7. Two sliding seats 11 are provided below the lamp holder 7 on the inner side wall of the cultivation rack 1. A cultivation tray 12 is slidably connected between the two sliding seats 11.

[0019] like Figure 4As shown, in this utility model, a bearing seat 13 is fixedly installed on the top of the cultivation rack 1, and the end of the bidirectional lead screw 4 away from the motor 3 is connected to the bearing seat 13. This enables the bidirectional lead screw 4 to remain stable during rotation, reducing transmission errors caused by axial movement, thereby improving the smoothness and accuracy of the lamp holder 7 lifting and lowering. In addition, the setting of the bearing seat 13 also shares the radial load of the output end of the motor 3, extending the service life of the motor 3 and the bidirectional lead screw 4.

[0020] like Figure 4 As shown, in this utility model, the tops of the two lead screw sleeves 5 are fixedly connected to limit sliders 14. The top wall of the cultivation rack 1 is provided with a limit groove for the limit sliders 14 to slide, which prevents the lead screw sleeves 5 from rotating circumferentially during the rotation of the bidirectional lead screw 4, ensuring that it only moves in a straight line along the axial direction. The fit clearance between the limit sliders 14 and the limit grooves is precisely calculated, which can ensure smooth sliding and effectively suppress shaking, thereby improving the operational stability of the entire device.

[0021] like Figure 1 and Figure 4 As shown, in this utility model, both ends of the connecting rod 9 are hinged to the connecting seat 6 and the connecting seat 8 respectively through a rotating shaft, so that the connecting rod 9 can automatically adjust the angle according to the lifting height of the lamp holder 7, avoiding the problem of jamming or stress concentration caused by rigid connection.

[0022] like Figure 1-4 As shown, in this utility model, both sides of the lamp holder 7 are fixedly connected with guide sliders 15 that pass through the side wall of the cultivation rack 1. Both sides of the cultivation rack 1 are provided with guide grooves for the guide sliders 15 to pass through and slide. The cooperation between the guide sliders 15 and the guide grooves restricts the rotational freedom of the lamp holder 7 and also distributes the load through surface contact, reducing the risk of deformation caused by single-point force. This ensures that the lamp holder 7 remains horizontal during the lifting process, ensuring the parallelism between the fluorescent lamp 10 and the cultivation tray 12, thereby improving the uniformity of illumination.

[0023] like Figure 1 , Figure 3 , Figure 4 As shown, in this utility model, both sides of the cultivation tray 12 are fixedly connected with sliding blocks 16 that are slidably connected to the sliding seat 11. The rear end of the sliding seat 11 is a closed structure and the front end of the sliding seat 11 is provided with a limiting mechanism 17 that cooperates with the sliding blocks 16, so that the cultivation tray 12 can be easily pushed in or pulled out like a drawer, which greatly facilitates daily cleaning, disinfection and seedling transplanting operations. In addition, the design of the limiting mechanism 17 also ensures that the cultivation tray 12 will not slide out due to vibration or misoperation during the operation of the device, thus improving the safety of use.

[0024] like Figure 5As shown, the limiting mechanism 17 of this utility model includes a movable block 1701 disposed above the sliding seat 11. A limiting post 1702 is fixedly connected to the bottom of the movable block 1701, which passes through the top wall of the sliding seat 11 and cooperates with the sliding block 16. The movable block 1701 and the sliding seat 11 are connected by a spring 1703 sleeved on the outside of the limiting post 1702. A pull ring 1704 is fixedly connected to the top of the movable block 1701.

[0025] When the culture tray 12 needs to be removed, simply pull the pull ring 1704 upwards to disengage the limiting post 1702 from the limiting hole on the sliding block 16, and the culture tray 12 can be pulled out smoothly. When inserting, simply align the sliding block 16 with the sliding seat 11 and push it in. The limiting post 1702 will automatically reset under the action of the spring and lock into the limiting hole to complete the fixation. This design not only ensures the reliability of the limiting but also simplifies the operation steps and significantly improves the convenience of use.

[0026] Working Principle: In practical implementation, the motor 3 is first started, driving the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 has two symmetrically arranged lead screw sleeves 5 threadedly connected to it, and the top of each lead screw sleeve 5 engages with a limiting slide groove on the top wall of the cultivation rack 1 via a limiting slider 14, the lead screw sleeves 5 will move towards or away from each other as the bidirectional lead screw 4 rotates. During this process, the connecting seat 1 6 moves along with the lead screw sleeves 5, and transmits force to the connecting seat 2 8 through the hinged connecting rod 9, thereby driving the lamp holder 7 to perform a smooth lifting and lowering motion.

[0027] The raising and lowering of the lamp holder 7 enables stepless adjustment of the distance between the fluorescent lamp 10 and the cultivation tray 12. When the seedlings are at different growth stages and have different light intensity requirements, the height of the lamp holder 7 can be adjusted by controlling the forward and reverse rotation of the motor 3, thereby changing the distance between the fluorescent lamp 10 and the cultivation tray 12 to meet the light conditions required for seedling growth.

[0028] Meanwhile, the cultivation tray 12, through the sliding connection between the sliding block 16 and the sliding seat 11, and the cooperation of the limiting mechanism 17, enables convenient pushing and pulling for placement and removal. When cleaning, disinfection, or seedling transplanting is required, simply pull the pull ring 1704 upwards to disengage the limiting post 1702 from the limiting hole on the sliding block 16, allowing the cultivation tray 12 to be pulled out smoothly. After completing the relevant operations, align the sliding block 16 with the sliding seat 11 and push it in. The limiting post 1702 automatically resets under the action of the spring 1703 and engages with the limiting hole, completing the fixation.

[0029] This design not only effectively meets the different light intensity requirements of seedlings at different growth stages, but also greatly facilitates the cleaning, disinfection and seedling transplanting of the cultivation tray 12, significantly improving the convenience of use and cultivation efficiency.
