Description

Technical Field

[0001] This application relates to the field of agricultural planting, and in particular to a novel corn breeding and cultivation rack device. Background Technology

[0002] In maize breeding and large-scale seedling production, cultivation racks are core equipment. However, traditional products have many defects and are difficult to adapt to the needs of precision breeding. Maize seedlings need to adjust the plant spacing from 5-10cm to 15-20cm according to the growth stage (germination to tillering stage). However, traditional cultivation rack containers are mostly fixed installations or require manual overall movement and adjustment. There are no standardized settings, which easily leads to crowded seedlings and uneven growth, affecting the consistency of experiments. Moreover, breeding often requires multi-variety and multi-stage comparative experiments. The traditional container's "integrated cavity" design means that seedlings of different varieties or growth stages share the same cultivation space. The roots are prone to intertwining and competing for nutrients and water, resulting in distorted experimental data. Furthermore, it is impossible to flexibly adjust the cultivation conditions for individual seedlings. Utility Model Content

[0003] To address the above problems, this application provides a novel corn breeding and cultivation rack device.

[0004] The novel corn breeding and cultivation rack device provided in this application adopts the following technical solution: A novel corn breeding cultivation rack device includes: a concave main frame, serving as the main support structure of the device; two sets of T-shaped frames, symmetrically distributed at both ends of the top surface of the concave main frame; two sets of side rails, respectively fixedly connected to the top sides of the two sets of T-shaped frames, with the length direction of the side rails aligned with the length direction of the T-shaped frames, forming a horizontal support track; multiple cultivation troughs, evenly distributed between the two sets of side rails along the length direction of the side rails; a sliding groove, formed along the length direction of the side rails on the side wall opposite to the cultivation trough, for providing sliding guidance; and two positioning sleeves, respectively installed on the outer walls of the two sides of the cultivation trough by screws, and slidingly engaging with the corresponding side rails.

[0005] Preferably, it also includes a plurality of slots, which are evenly formed on the wall of the groove along the length of the side rail; two locking plates, which are slidably disposed at both ends of the slot, with one end of the locking plate extending into the groove and the other end located inside the slot, and can slide within the slot in a direction perpendicular to the length of the side rail; a fixing plate, which is fixedly disposed at the center of the slot between the two locking plates; and two springs, which are fixed between the fixing plate and the two locking plates respectively.

[0006] Preferably, it also includes a rectangular opening that passes through the positioning sleeve and is connected to the sliding groove. The length direction of the rectangular opening is consistent with the sliding direction of the card plate. There are two push plates that are slidably disposed at both ends of the rectangular opening. One end of the push plate extends to the outside of the positioning sleeve, and the other end extends into the rectangular opening and connects to the corresponding card plate.

[0007] Preferably, it also includes a rectangular plate disposed at the top opening of the cultivation tank; and multiple cultivation holes, which are horizontally and equidistantly opened on the top surface of the rectangular plate for placing the breeding substrate and seedlings.

[0008] Preferably, it also includes rectangular retaining rings, multiple of which are respectively disposed below each incubation hole, with their bottom surfaces connected to the inner bottom surface of the incubation tank; a rectangular retaining frame, which is fitted inside the rectangular retaining rings, with its top surface connected to the bottom surface of the rectangular plate; and multiple ventilation holes, which are evenly distributed and opened through the four side walls of the rectangular retaining frame.

[0009] Preferably, the distance between two adjacent slots is 5cm, providing multiple fixed positions for positioning the incubation tank.

[0011] Preferably, one end of the spring is fixedly connected to the fixing plate, and the other end is fixedly connected to the locking plate. In its natural state, the spring pushes the locking plate into the locking groove, thereby blocking and limiting the positioning sleeve.

[0012] In summary, this application includes the following beneficial technical effects: 1. The flexible positioning structure allows the cultivation trough to slide along the side rail, and the plant spacing can be adjusted in 5cm increments to meet the space requirements of corn at different growth stages. It can also limit the vertical and horizontal displacement of the positioning sleeve during the sliding process to ensure smooth sliding and prevent the cultivation trough from tilting, which could cause substrate spillage or seedling lodging. 2. Independent micro-cultivation units avoid root entanglement and nutrient competition among seedlings of different varieties and stages, facilitate individual substrate control and management, ensure accurate breeding data, improve success rate, and promote air circulation in the trough to regulate substrate humidity and oxygen content, reduce root rot and other problems, and improve seedling survival rate.

[0015] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0016] This application discloses a novel corn breeding cultivation rack device, referring to... Figure 1 The device includes a concave main frame 1, which serves as the main support structure. Compared to traditional straight rod supports, its concave structure can distribute the overall weight of the device, reduce the risk of center of gravity shift, and provide a stable foundation support for the upper structure. There are two sets of T-shaped frames 2, which are symmetrically distributed at both ends of the top surface of the concave main frame 1 to form a two-point stable fixation, preventing the side rails 3 from bending and deforming due to unilateral force, and further enhancing the overall rigidity of the device.

[0017] Reference Figure 1 and Figure 3 The side rails 3 are provided in two sets, which are fixedly connected to the top of the two T-shaped frames 2 on both sides respectively. The length direction of the side rails 3 is consistent with the length direction of the T-shaped frames 2, forming a horizontal support track. The inner wall of the side rails 3 is provided with a wear-resistant coating (polytetrafluoroethylene material) to reduce the wear of the positioning sleeves 10 when sliding. The incubation tank 4 is provided in multiple sets, which are evenly distributed between the two sets of side rails 3 along the length direction of the side rails 3. The sliding groove 17 is opened on the side wall opposite to the side rail 3 and along the length direction of the side rail 3 to provide sliding guidance. There are two positioning sleeves 10, which are installed on the outer walls of the two sides of the incubation tank 4 by screws and slide with the corresponding side rails 3 respectively. The distance between two adjacent slots 12 is 5cm, providing multiple fixed positions for positioning the incubation tank 4. The cross-section of the sliding groove 17 is U-shaped, and the inner side wall of the positioning sleeve 10 fits against the outer side wall of the side rail 3.

[0018] The sliding fit between the positioning sleeve 10 and the side rail 3 breaks the limitation of the traditional fixed and immovable cultivation trough box 4. Planters can push the cultivation trough box 4 to slide along the side rail 3 according to the plant spacing requirements of different growth stages of corn seedlings, and adjust the spacing between adjacent cultivation trough boxes 4. The concave cross section of the slide groove 17 fits the inner side wall of the positioning sleeve 10, which can limit the vertical and horizontal displacement of the positioning sleeve 10 during the sliding process, ensuring smooth sliding and preventing the cultivation trough box 4 from tilting, which may cause the substrate to spill or the seedlings to fall over. The setting of the 5cm fixed position provides a standardized reference for spacing adjustment, eliminating the need for additional measurement, improving operational efficiency, and ensuring uniform plant spacing, which is beneficial to seedling photosynthesis and nutrient absorption.

[0019] Reference Figures 3-5 It also includes multiple slots 12, which are evenly distributed along the length of the side rail 3 on the wall of the slide groove 17. Two locking plates 13 are slidably disposed at both ends of the slots 12, with one end of the locking plate 13 extending into the slide groove 17 and the other end located inside the slot 12, allowing it to slide within the slot 12 in a direction perpendicular to the length of the side rail 3. A fixing plate 15 is fixedly disposed at the center of the slot 12 between the two locking plates 13. The multiple slots 12 are evenly distributed along the length of the side rail 3, and are pushed by the spring 14. The design of the plate 13 extending into the slide groove 17 allows the plate 13 to automatically engage with the groove 12 under the elastic force of the spring 14 when the cultivation tank box 4 slides to the target position, thus achieving automatic locking of the cultivation tank box 4 without the need for external bolts, clips, or other tools, making operation convenient. At the same time, the two sets of plates 13 extend from both ends of the groove 12 respectively, forming a bidirectional limit on the positioning sleeve 10. Compared with single-sided limit, this can effectively prevent the cultivation tank box 4 from shifting under the action of external forces such as wind or collisions during manual operation, ensuring a stable seedling growth environment.

[0020] Reference Figure 4 Two springs 14 (cylindrical helical compression springs) are provided, which are respectively fixed between the fixed plate 15 and the two clamping plates 13. One end of the spring 14 is fixedly connected to the fixed plate 15, and the other end is fixedly connected to the clamping plate 13. In the natural state, the spring 14 pushes the clamping plate 13 into the clamping groove 12 to form a blocking limit on the positioning sleeve 10. It also includes a rectangular opening 16, which is opened through the positioning sleeve 10 and is connected to the sliding groove 17. The length direction of the rectangular opening 16 is consistent with the sliding direction of the clamping plate 13. Two press plates 11 are provided, which are slidably set at both ends of the rectangular opening 16. One end of the press plate 11 extends to the outside of the positioning sleeve 10, and the other end extends into the rectangular opening 16 and connects to the corresponding clamping plate 13.

[0021] One end of the push plate 11 extends to the outside of the positioning sleeve 10, and the other end is connected to the clamping plate 13. When the position of the cultivation trough box 4 needs to be adjusted again, the grower only needs to press the outer push plate 11, which will drive the clamping plate 13 to compress the spring 14, so that the clamping plate 13 is retracted into the slide groove 17, releasing the restriction on the positioning sleeve 10. Then, the cultivation trough box 4 can be pushed to slide. The entire adjustment process does not require bending over or using tools to reach into the device, which reduces labor intensity and is especially suitable for multi-layer breeding racks or large-area breeding scenarios, improving management efficiency.

[0022] Reference Figure 2 It also includes a rectangular plate 6, which is set at the top opening of the cultivation trough 4. The edge of the rectangular plate 6 is attached to the inner side wall of the cultivation trough 4. Multiple cultivation holes 5 are set and are horizontally and equidistantly opened on the top surface of the rectangular plate 6 for placing the breeding substrate and seedlings. Each cultivation hole 5 corresponds to one seedling, which can achieve uniform distribution of seedlings and avoid the problems of seedling crowding and uneven growth caused by traditional broadcasting methods.

[0023] It also includes rectangular retaining rings 7, multiple of which are respectively set below each cultivation hole 5, with their bottom surfaces connected to the inner bottom surface of the cultivation trough 4; rectangular retaining frames 8, which are fitted inside the rectangular retaining rings 7, with their top surfaces connected to the bottom surface of the rectangular plate 6; and multiple ventilation holes 9, which are evenly distributed on the four side walls of the rectangular retaining frames 8. The multiple ventilation holes 9 on the four side walls of the rectangular retaining frames 8, fitted inside the rectangular retaining rings 7, form a three-dimensional ventilation channel, which can promote air circulation inside the cultivation trough 4, reduce substrate humidity, and reduce root rot caused by lack of oxygen in corn seedlings. At the same time, in the process of corn breeding, corn seedlings of different growth stages and varieties in the cultivation trough 4 have significant differences in their needs for growth space and nutrient supply. The rectangular retaining frames 8 and rectangular retaining rings 7 restrict the root system to the inside of the rectangular retaining frames 8, avoiding the intertwining of the root systems of different varieties at different growth stages and preventing them from competing for nutrients, thus ensuring the accuracy of breeding test data.

[0024] The implementation principle of a novel corn breeding cultivation rack device in this application embodiment is as follows: When in use, the positioning sleeve 10 slides with the side rail 3, and forms an elastic positioning structure by combining the locking plate 13 driven by the spring 14 and the pressing plate 11. Pressing the pressing plate 11 can unlock the cultivation trough box 4, and the plant spacing can be adjusted by sliding along the side rail 3 (5cm level standardization). After releasing, the spring 14 pushes the locking plate 13 to automatically lock, ensuring that the trough box is stable and does not shift.

[0025] Then, by matching the cultivation holes 5, rectangular clips 7, and clip frames one-to-one, the cultivation trough 4 is divided into independent micro-units, each unit accommodating one seedling, avoiding root intertwining and nutrient competition, and adapting to the differentiated cultivation needs of different varieties and growth stages.

[0026] Finally, the rectangular card frame 8 with ventilation holes 9 on all four sides creates a three-dimensional ventilation channel, accelerates the water and air circulation of the substrate, reduces the risk of root rot, creates a suitable growth environment for the root system, and forms a breeding solution with optimized whole process.
