Description

Technical Field

[0001] This utility model relates to the field of rice breeding technology, and in particular to a breeding isolation cover for rice breeding. Background Technology

[0002] As one of the world's major food crops, rice is crucial for ensuring food security by increasing its yield through breeding. However, in the process of rice breeding, some seedlings or special breeding materials may be more sensitive to pests and diseases. In order to prevent pests from invading, it is necessary to use isolation covers to cover the rice seedlings and isolate them. This not only reduces pest damage but also prevents some animals from contacting the rice and cross-pollinating it, thus affecting the purity of the rice.

[0003] While the current isolation covers can effectively isolate pests and prevent cross-pollination of rice, they have certain requirements for ventilation at different stages of rice breeding. For example, during seed germination, seed respiration is relatively weak, so a small amount of ventilation is sufficient to meet the seed's needs. As the seed grows, the required ventilation is also larger. The existing isolation covers are not convenient for adjusting the ventilation required according to the different stages of rice breeding.

[0004] Therefore, based on the above situation, it is necessary to design a breeding isolation cover for rice breeding to solve the above problems. Utility Model Content

[0005] This invention provides a breeding isolation cover for rice breeding, which solves the problem in the prior art of easily adjusting the ventilation volume according to the different stages of rice breeding.

[0007] A breeding isolation cover for rice breeding includes a breeding rack for placing rice seedlings. A transparent cover cylinder is detachably mounted on the breeding rack via a connector. The transparent cover cylinder is used to isolate the rice seedlings on the breeding rack. The transparent cover cylinder includes an inner cover cylinder and an outer cover cylinder coaxially arranged and rotatably connected to the inner cover cylinder. Both the inner cover cylinder and the outer cover cylinder have multiple ventilation windows of the same number at equal intervals. By rotating the outer cover cylinder, the overlapping area of ​​the ventilation windows of the inner cover cylinder and the outer cover cylinder can be adjusted, thereby adjusting the amount of ventilation inside the transparent cover cylinder.

[0008] Preferably, the connector includes a magnet one disposed on the inner cover cylinder and a magnet two disposed on the breeding rack, wherein the magnet one and the magnet two are attracted to each other.

[0009] Preferably, the inner cover is provided with a rotating rod, which is damped and rotatably connected to the outer cover.

[0010] Preferably, the ventilation window on the outer cover cylinder is detachably equipped with a protective net, which is used to prevent foreign objects from entering the interior of the transparent cover cylinder.

[0012] Preferably, the outer wall of the inner cover is fitted to the inner wall of the outer cover.

[0013] The beneficial effects of this utility model are: by isolating the rice seedlings on the breeding rack through the transparent cover cylinder, the damage of the external environment to the rice seedlings is reduced; and at different stages of rice breeding, by rotating the outer cover cylinder, the overlapping area of ​​the ventilation windows of the outer cover cylinder and the inner cover cylinder is adjusted, so that the ventilation volume inside the transparent cover cylinder can be adjusted to meet the growth needs of rice seedlings at different breeding stages.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figure 1-Figure 5 As shown, a breeding isolation cover for rice breeding includes a breeding rack 1. In use, rice seeds are planted on the breeding rack 1. To prevent the rice seeds from being damaged by external pests, a transparent cover cylinder is detachably mounted on the breeding rack 1 via a connector. The transparent cover cylinder includes an inner cover cylinder 31 and an outer cover cylinder 32 coaxially arranged and rotatably connected to the inner cover cylinder 31. The transparent cover cylinder covers the rice seedlings to isolate them from the rice seedlings on the breeding rack 1, reducing pest damage. The transparent cover cylinder can be made of materials such as PC or PE. In its transparent state, it allows for timely observation of the rice's growth and development. However, since different stages of rice growth require specific ventilation conditions, it is necessary to... Proper ventilation is provided for rice seedlings. When ventilating rice seedlings, the outer cover cylinder 32 is rotated. At this time, the multiple ventilation windows 5 of the same number on the inner cover cylinder 31 and the outer cover cylinder 32 are staggered. When the overlapping area of ​​the ventilation windows 5 on the inner cover cylinder 31 and the outer cover cylinder 32 increases, the ventilation volume is larger. When the overlapping area of ​​the ventilation windows 5 on the inner cover cylinder 31 and the outer cover cylinder 32 decreases, the ventilation volume decreases. For example, during the germination stage of rice seeds, the ventilation volume requirement is small, so the overlapping area of ​​the ventilation windows 5 on the inner cover cylinder 31 and the outer cover cylinder 32 can be reduced. During the growth stage of rice seedlings, the overlapping area of ​​the ventilation windows 5 on the inner cover cylinder 31 and the outer cover cylinder 32 can be increased, thereby adapting to the ventilation volume requirements of different growth stages of rice breeding.

[0023] Reference Figure 5 As shown, further, in order to keep the inner cover cylinder 31 fixed to the breeding rack 1, the connecting parts include a magnet 21 on the inner cover cylinder 31 and a magnet 22 on the breeding rack 1. The magnet 21 and the magnet 22 attract each other. When the transparent cover cylinder is covered on the breeding rack 1, a magnetic field is generated between the magnet 21 and the magnet 22 to fix the transparent cover cylinder on the breeding rack 1. No tools or complicated connecting parts are needed. At the same time, the fixing of the inner cover cylinder 31 also makes it easy to rotate the outer cover cylinder 32 to change the overlapping area of ​​the ventilation window 5 of the inner cover cylinder 31 and the outer cover cylinder 32, which is more convenient to use.

[0024] Reference Figure 1-Figure 4As shown, furthermore, to facilitate the adjustment of the overlapping area of ​​the ventilation window 5 at the inner cover cylinder 31 and the outer cover cylinder 32, a rotating rod 4 is provided on the inner cover cylinder 31. The rotating rod 4 is connected to the outer cover cylinder 32 in a damped rotational manner. When the outer cover cylinder 32 is rotated, the rotating rod 4 allows for relatively easy rotation of the outer cover cylinder 32. The damped rotation provides appropriate resistance, ensuring that the rotation is not difficult due to excessive resistance, nor that the outer cover cylinder 32 rotates arbitrarily due to insufficient resistance. This allows the user to precisely control the size adjustment of the ventilation window 5 to meet the ventilation requirements of rice seedlings at different stages. When the rotation of the outer cover cylinder 32 stops, the damped rotational connection can maintain the relative position of the inner cover cylinder 31 and the outer cover cylinder 32 to a certain extent, preventing the outer cover cylinder 32 from rotating due to slight external interference, such as a breeze or a slight collision, which would change the size of the ventilation window 5. This ensures that the set ventilation conditions are relatively stable, providing a continuous and stable ventilation environment for rice seedlings, which is beneficial to the growth and development of the seedlings.

[0025] Reference Figure 1-Figure 4 As shown, furthermore, in order to prevent pests and other external objects from affecting the rice growth process, a protective net 6 can be detachably connected to the ventilation window 5 on the outer cover cylinder 32 through screws, buckles and other structures. The protective net 6 can act as a physical barrier to effectively prevent pests (such as rice planthoppers, rice leaf rollers, thrips, etc.) from entering the isolation cover. These pests can cause serious damage to rice seedlings and plants. They may suck plant sap, spread diseases or bite leaves. The protective net 6 can block them outside, providing a relatively safe space for rice growth and reducing the probability of pests and diseases. In addition, a protective net 6 with a suitable mesh size can be installed according to actual use needs to prevent pollen from entering the inside of the transparent cover cylinder and affecting the purity of the rice. The detachable connection method also makes it easy to replace and disassemble the protective net 6.

[0026] Reference Figure 1-Figure 4 As shown, furthermore, in order to record the opening amount of the ventilation window 5 each time, a pointer 7 is connected to the outside of the outer casing 32, with one end of the rotating rod 4 extending to it. The outer casing 32 has a circular scale line 8, and the rotating rod 4 is located at the center of the circular scale line 8. When the outer casing 32 is rotated, the pointer 7 will change the value indicated on the circular scale line 8. For example, when the outer casing 32 is rotated, the pointer 7 initially points to the 0 mark. After rotation, the pointer 7 points to the 3 mark. At this time, the position pointed to by the pointer 7 can be manually recorded. The use of the pointer 7 and the circular scale line 8 can clearly and intuitively display the opening amount of the ventilation window 5 each time. When ventilation is carried out again, the value of this time can be compared, and the operator can accurately know the degree to which the ventilation window 5 is opened.

[0027] Reference Figure 3As shown, furthermore, to prevent a large gap between the inner cover 31 and the outer cover 32, the outer wall of the inner cover 31 is fitted with the inner wall of the outer cover 32. When the inner cover 31 and the outer cover 32 are fitted together, they support each other, which can enhance the structural stability of the entire cover. When facing various forces from the external environment, such as wind, slight collisions or vibrations, the fitted structure can better resist these external forces and prevent the cover from deforming or being damaged. This helps to extend the service life of the isolation cover and ensure that it can continuously and stably protect rice seedlings during rice seedling cultivation. At the same time, the fitted structure can reduce air leakage to a certain extent. Especially when it is necessary to adjust the ventilation window 5 for ventilation, it can ensure that the ventilation volume can be precisely controlled according to the design requirements, avoiding the impact of air leakage caused by the gap between the inner and outer covers on the environmental control effect, and making the environmental conditions inside the cover more in line with the needs of different stages of rice seedling cultivation.
