Description

Technical Field

[0001] This utility model relates to the field of protective cylinder technology, and in particular to a retractable transparent protective cylinder for cabbage breeding. Background Technology

[0002] The core of Chinese cabbage breeding is to cultivate superior varieties that better meet market demands and planting environments through genetic improvement. Breeding goals are adjusted according to planting areas, consumer habits, and market demand, mainly focusing on the following three aspects: Quality Improvement: Enhancing taste, such as reducing fiber and increasing crispness; optimizing appearance, such as head compactness and uniform color (e.g., green heads, white heads, yellow hearts); improving flavor and reducing bitterness or earthy taste. Enhanced Resistance: Improving resistance to pests and diseases, with common targets including downy mildew, soft rot, aphids, and cabbage caterpillars; enhancing environmental adaptability, such as tolerance to low temperatures (suitable for early spring / late autumn planting), high temperatures (suitable for summer planting), and salinity. Increased Yield: While ensuring quality, increasing yield by optimizing plant type, shortening the growth cycle, and increasing the weight per plant or planting density per unit area.

[0003] In existing technologies, during cabbage breeding experiments, cabbage undergoes significant morphological changes from the seedling stage to the mature stage, with plant height increasing from approximately 10 cm to 60-70 cm and crown width expanding from 15 cm to 40-50 cm. Traditional fixed protective structures cannot adapt to these dynamic changes, which may lead to restricted plant growth or the need for frequent replacement of protective facilities at different heights, increasing operational complexity and cost. Summary of the Invention

[0004] This utility model mainly provides a retractable transparent protective tube for cabbage breeding that can conveniently improve protection efficiency and prevent plant growth restriction.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a retractable transparent protective tube for cabbage breeding, comprising: a protective tube body 1, a base plate 5 fixedly installed on the outer wall of the protective tube body 1, a support rod 6 fixedly installed on the top of the base plate 5, a plurality of evenly distributed slots 7 opened on the outer wall of the support rod 6, a top seat 4 slidably installed on the outer wall of the support rod 6, the bottom of the top seat 4 being fixedly connected to the top of the protective tube body 1, a limiting groove 9 opened on the inner wall of the top seat 4, a through opening 10 through the top surface of the limiting groove 9, a spring 11 fixedly installed on the inner wall of the limiting groove 9, a locking block 12 fixedly installed on one end of the spring 11, and a pull plate 13 fixedly installed on the end of the locking block 12 near the through opening 10.

[0019] like Figure 1 and Figure 5As shown, a connecting frame 2 is installed through and fixedly mounted on the inner wall of the protective cylinder body 1. A storage slot 16 is opened on the top surface inside the connecting frame 2. A fixing plate 17 is slidably installed inside the storage slot 16. A threaded groove 18 is opened on the top of the fixing plate 17. A threaded rod 19 is threadedly connected inside the threaded groove 18. A handle 20 is fixedly mounted through the connecting frame 2 on the top of the threaded rod 19. When the operator rotates the handle 20, the handle 20 drives the threaded rod 19 to rotate, so that the fixing plate 17 moves along the storage slot 16.

[0020] like Figure 1 and Figure 5 As shown, a ventilation louver 3 is slidably installed inside the connecting frame 2. A fixing groove 15 is provided on the top of the ventilation louver 3. A limit ring 21 is fixedly installed on the inner wall of the connecting frame 2. When the outer wall of the ventilation louver 3 is in contact with the limit ring 21, the fixing groove 15 is located below the fixing plate 17.

[0021] like Figure 5 As shown, the outer wall of the fixing plate 17 is in contact with the inner wall of the storage groove 16 to prevent the fixing plate 17 from rotating when the threaded rod 19 rotates.

[0022] like Figure 4 As shown, a baffle 14 is fixedly installed on the outer wall of the pull plate 13 to prevent external dust from entering the limiting groove 9.

[0023] like Figure 3 As shown, a limit plate 8 is fixedly installed on the top of the support rod 6 to prevent the top seat 4 from moving excessively away from the support rod 6.

[0024] like Figure 5 As shown, the outer wall of the ventilation louver 3 is fitted with the inner wall of the connecting frame 2, and the inner wall of the fixing groove 15 is fitted with the outer wall of the fixing plate 17. When the fixing plate 17 enters the fixing groove 15, the ventilation louver 3 can be fixed.

[0025] The device's usage and working principle are as follows: During use, the operator places the bottom of the protective cylinder body 1 into a pot of cultivated cabbage with an inlet diameter of 20-30 cm. Then, pulling the pull plate 13 causes the locking block 12 to disengage from the slot 7, compressing the spring 11. The operator then pulls the top seat 4, which rises along the support rod 6, stretching the protective cylinder body 1. The stretching length of the protective cylinder body 1 is controlled according to the cabbage's growth. After adjustment, the operator releases the pull plate 13, and the spring force pushes the locking block 12 into the corresponding slot 7, thus securing it. This eliminates the need for frequent replacement of the protective device and adapts to the volume growth requirements of the cabbage throughout its entire growth cycle. During ventilation, the operator can adjust airflow by rotating the angle of the fan blades on the ventilation louvers 3, reducing disease occurrence and improving breeding success rates. When there is too much dust on the ventilation louver 3, the worker rotates the handle 20, which drives the threaded rod 19 to rotate, causing the fixing plate 17 to rise along the storage groove 16 and leave the fixing groove 15. At this time, the worker can pull out the ventilation louver 3 from inside the connecting frame 2, clean it, and then reset the ventilation louver 3. When the outer wall of the ventilation louver 3 is in contact with the limiting ring 21, the worker rotates the handle 20 in the opposite direction, and the fixing plate 17 enters the fixing groove 15. This completes the installation and improves cleaning efficiency. The protective cylinder body 1 is made of transparent PET, PC, or PVC material with a light transmittance of not less than 85%. The good light transmittance ensures that the cabbage can receive normal sunlight, increasing the photosynthetic efficiency of the cabbage by about 10%-15%.
