Description

Technical Field

[0001] This utility model relates to the field of rice breeding technology, and in particular to a temperature and humidity control seedling raising box for rice breeding. Background Technology

[0002] Rice breeding is a process of improving yield, resistance, and adaptability by selecting and cultivating high-quality rice varieties. Seedling trays, as an important tool in the breeding process, are used to cultivate rice seeds and provide suitable environmental conditions for rice growth. Through proper management and control of factors such as temperature and humidity, seedling trays can help rice seeds germinate successfully in the early stages and provide strong seedlings for subsequent transplanting.

[0003] Traditional rice seedling trays typically consist of a box, a base, a drainage system, and a surface covering material. The box provides space to hold the seedling soil and water, the base helps support and stabilize the soil, and the drainage system ensures excess water is drained away, preventing waterlogging from affecting rice growth. The surface covering material provides appropriate shading, helps regulate ambient temperature and humidity, and creates conditions favorable for rice growth.

[0004] Traditional seedling trays cannot be used for tiered seedling cultivation, usually because the tray design does not take into account tiered planting functionality. This leaves rice seedlings of different heights facing problems of insufficient light and space, resulting in uneven growth. Within the same seedling tray, seedlings cannot receive even light due to mutual shading, which not only affects the overall growth and development of the seedlings but also leads to a lower survival rate after transplanting. Seedling trays lacking tiered design fail to maximize the use of space and resources, reducing seedling cultivation efficiency and increasing breeding costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temperature and humidity controlled seedling raising box for rice breeding, which aims to improve the problems of traditional seedling raising boxes that cannot be layered for seedling raising, making it difficult to maximize the use of space and resources, reducing seedling raising efficiency and increasing breeding costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature and humidity control seedling raising box for rice breeding, comprising a box body, wherein multiple layered plates are provided inside the box body, and multiple fixed seats are fixedly connected inside the box body, and a limit component is provided on the side wall of each layered plate.

The sliding shaft is slidably connected inside the sleeve shaft. A spring is sleeved on the outer wall of the sleeve shaft and the sliding shaft. Both ends of the spring are fixedly connected to the outer wall of the sleeve shaft and the outer wall of the sliding shaft, respectively. A sealing assembly is provided on the top of the housing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a rice breeding temperature and humidity control seedling box, including a box body 1. The box body 1 is made of PP plastic, which is moisture-resistant and resistant to decay in the rice seedling environment. It can provide a closed growth space for seedlings, avoid external dust and impurities from polluting the seedling environment, and bear the weight of the layered plates 2 and the seedlings to ensure the stability of the overall structure. This is common knowledge and will not be described in detail here. The box body 1 is provided with multiple layered plates 2. The layered plates 2 can divide the interior of the box body 1 into multiple independent seedling areas, which can cultivate rice seedlings at different growth stages at the same time. This avoids the problem of low space utilization in traditional single-layer seedling boxes, and at the same time prevents the upper layer seedlings from blocking the lower layer seedlings from the light, ensuring that each layer of seedlings can get balanced light and promote uniform growth. Multiple fixed seats 3 are fixedly connected inside the box body 1, and each layered plate 2 has a limit component on its side wall.

[0031] The limiting assembly includes multiple limiting shafts 10, whose sidewalls are fixedly connected to the sidewalls of each layer plate 2. Each limiting shaft 10 can be inserted between two clamping plates 5. Through its own structure and the clamping force of the clamping plates 5, it restricts the lateral and vertical movement of the layer plate 2, preventing loosening or displacement after installation. Each fixing seat 3 has multiple fixing shafts 4 fixedly connected inside. The fixing shafts 4 cooperate with the clamping plates 5 for rotational support. The clamping plates 5 can rotate flexibly around the fixing shafts 4, providing opening and closing space for the insertion of the limiting shafts 10, ensuring that the limiting shafts 10 can smoothly engage between the two clamping plates 5. The outer wall of each fixing shaft 4 is rotatably connected to... There are clamping plates 5, and each clamping plate 5 has a connecting plate 6 fixedly connected to its side wall. The right connecting plate 6 has a sliding shaft 8 rotatably connected inside, and the left connecting plate 6 has a sleeve shaft 7 rotatably connected inside. The sliding shaft 8 is slidably connected inside the sleeve shaft 7. The sleeve shaft 7 and the outer wall of the sliding shaft 8 are fitted with a spring 9. The spring 9 is made of 65Mn spring steel, which has excellent elasticity and fatigue resistance, and can provide continuous clamping force for the clamping plate 5 to avoid the spring force from weakening after long-term use and causing the layered plate 2 to loosen. This is common knowledge and will not be elaborated on here. The two ends of the spring 9 are fixedly connected to the outer walls of the sleeve shaft 7 and the sliding shaft 8, respectively. A sealing component is provided on the top of the box body 1.

[0032] Reference Figure 1 and Figure 4The sealing assembly includes a lid 11, which is rotatably connected to the top of the box body 1. The lid 11 closes the top opening of the box body 1, preventing the controlled temperature and humidity inside the box from escaping. It also isolates the seedling environment from external dust and airflow, providing stable growth conditions for rice seedlings and solving the problem of large temperature and humidity fluctuations caused by poor sealing in traditional seedling boxes. This improves the quality of seedling cultivation. (Details omitted here.) A top shell 12 is fixedly connected to the side wall of the lid 11, and a bottom shell 13 is fixedly connected to the side wall of the box body 1. The top shell 12 and bottom shell 13 correspond vertically. When the lid 11 is closed, the top shell 12 fits over the outside of the bottom shell 13, forming the first sealing barrier and reducing the loss of temperature and humidity from the joint between the box body 1 and the lid 11. A positioning cavity 18 is provided inside the top shell 12, and the bottom shell 13... An internally fixed horizontal shaft 14 is connected, and multiple sliders 15 are slidably connected to the outer wall of the horizontal shaft 14. The sliders 15 cooperate with the horizontal shaft 14 and spring 19 to slide in linkage. When the positioning block 17 is squeezed by the positioning cavity 18, the slider 15 will slide to both sides along the horizontal shaft 14, and the spring 19 will be compressed. When the positioning block 17 is fully inserted into the positioning cavity 18, the spring 19 elastically resets and pushes the slider 15 to move in the opposite direction, causing the positioning block 17 to fit tightly against the inner wall of the positioning cavity 18, thereby achieving a stronger sealing effect. Each slider 15 has a positioning block 17 fixedly connected to its side wall, and the positioning block 17 is slidably connected inside the positioning cavity 18. Each slider 15 has a pressure plate 16 fixedly connected to its side wall. The outer wall of the horizontal shaft 14 is fitted with a spring 19, and the two ends of the spring 19 are fixedly connected to the side walls of multiple sliders 15 respectively.

[0033] Working principle: When installing the layered plate 2, the limiting shaft 10 on the side wall of the layered plate 2 will squeeze the clamping plate 5 inside the fixing seat 3. The clamping plate 5 rotates around the fixing shaft 4 and drives the connecting plate 6 on the side wall to move synchronously. The right connecting plate 6 drives the sliding shaft 8 to slide into the left sleeve shaft 7. The spring 9 on the outer wall of the sleeve shaft 7 and the sliding shaft 8 is stretched and produces elastic deformation. When the limiting shaft 10 is fully inserted between the two clamping plates 5, the spring 9 elastically returns to its original position, pulling the sleeve shaft 7 and the sliding shaft 8 to move in opposite directions, thereby driving the clamping plate 5 to clamp the limiting shaft 10, and firmly fixing the layered plate 2 in the box body 1. The spacing of the layered plates 2 can be flexibly adjusted according to the height of the seedlings, solving the problem of traditional seedling boxes not being able to be layered and improving space utilization. To address the low efficiency issue, when the lid 11 is closed, the top shell 12 on the side wall of the lid 11 moves down synchronously with the lid 11. The positioning cavity 18 inside the top shell 12 gradually fits onto the positioning block 17 on the bottom shell 13. The positioning block 17 is compressed, causing the slider 15 to slide along the horizontal axis 14. The second spring 19 on the outer wall of the horizontal axis 14 is compressed. When the positioning cavity 18 and the positioning block 17 are fully aligned, the second spring 19 elastically returns to its original position, pushing the slider 15 to tightly engage the positioning block 17 within the positioning cavity 18. At the same time, the pressure plate 16 on the side wall of the slider 15 adheres to the joint between the top shell 12 and the bottom shell 13, forming a double seal to prevent the loss of temperature and humidity inside the box, thus providing a stable growth environment for the rice seedlings.
