Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, specifically to a cold-proof protective cover for Chinese medicinal herb seedlings. Background Technology

[0002] In the practice of protecting Chinese medicinal herb seedlings from the cold, methods such as small arched sheds, fixed-height plastic covers, or direct covering with straw mats or non-woven fabrics are commonly used. These traditional methods have obvious limitations. First, many Chinese medicinal herb seedlings, such as Panax notoginseng, Coptis chinensis, and Bletilla striata, have biological characteristics of preferring shade, being intolerant of severe cold, and being averse to intense heat. Moreover, the height of seedlings varies significantly among different species or at different growth stages. Existing fixed-height protective covers cannot be flexibly adjusted to accompany the growth process of the seedlings, resulting in wasted space in the early stages and pressure on the stems and leaves and restriction of their expansion in the middle and later stages, which may cause mechanical damage or leaf rot. Second, Chinese medicinal herb seedlings are extremely sensitive to microenvironmental fluctuations. Their healthy growth requires stable temperature and humidity and moderate airflow to prevent diseases. However, the existing methods mainly rely on manually lifting the covering for ventilation, making it difficult to accurately control the size of the opening and adapt to the specific environmental needs of the seedlings. This results in extensive management and difficulty in guaranteeing effectiveness. Therefore, there is an urgent need for a cold-proof protective cover for Chinese medicinal herb seedlings.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a transparent cover 1, and several ventilation holes 2 with rounded corners are opened on the annular side wall of the transparent cover 1. An annular groove 13 is opened on the outer annular wall of the transparent cover 1, and a reflective strip 14 is fixedly installed in the annular groove 13. By utilizing the reflective properties of the reflective strip 14, a warning can be provided to personnel at night to avoid personnel accidentally colliding with it and damaging the seedlings. It also includes: The support ring 3 is fixedly sleeved on the transparent cover 1. A telescopic cover 4 is fixedly installed at the bottom of the support ring 3. A support bottom edge 5 is fixedly installed at the bottom of the telescopic cover 4. Several connecting blocks 11 with equal rounded corners are distributed on the outer ring wall of the support bottom edge 5. Ground nails 12 are fixedly installed at the bottom of the connecting blocks 11. The protective cover can be well fixed on the ground through the connecting blocks 11 and the ground nails 12 to prevent the protective cover from being blown away by the wind. A ventilation adjustment mechanism 6 is provided on the transparent cover 1. The internal threaded cylinder 7 consists of several cylinders, which are distributed with equal rounded corners on the upper part of the support bottom edge 5, and the internal threaded cylinder 7 is located on the outer side of the telescopic cover 4. The adjusting screws 8 are multiple in number and are respectively inserted into several internally threaded cylinders 7 by threaded rotation. The adjusting screws 8 are rotatably mounted on the support ring 3 by bearings. The support ring 3 is provided with a synchronous adjusting mechanism 9 connected to the adjusting screws 8. A telescopic sleeve 10 is fixedly provided at the upper end of the internally threaded cylinder 7 and is movably sleeved on the adjusting screws 8. The upper end of the telescopic sleeve 10 is fixedly connected to the bottom of the support ring 3. The telescopic sleeve 10 can protect the adjusting screws 8 and prevent dust and other impurities from falling on the adjusting screws 8 and causing the adjusting screws 8 to jam. The ventilation regulating mechanism 6 includes: Ventilation plate 6-1 is fixedly installed in the upper opening of the transparent cover 1. A rotating rod 6-2 is rotatably installed on ventilation plate 6-1 through a bearing. A rotating handle 6-3 is fixedly installed at the upper end of the rotating rod 6-2. Several ventilation holes 6-4 of type 2 are opened on ventilation plate 6-1 with rounded corners. The second ventilation plate 6-5 is movably abutting against the bottom of the first ventilation plate 6-1, and the second ventilation plate 6-5 is fixedly sleeved on the lower end of the rotating rod 6-2. The second ventilation plate 6-5 is provided with a third ventilation hole 6-6 that cooperates with the second ventilation hole 6-4. Connecting rods 6-7, there are several connecting rods 6-7, evenly distributed with rounded corners on the second ventilation plate 6-5. The lower end of the connecting rods 6-7 is fixedly provided with a sealing plate 6-8 that cooperates with the first ventilation hole 2. The ventilation adjustment mechanism 6 can not only adjust the size of the ventilation opening formed by the second ventilation hole 6-4 and the third ventilation hole 6-6, but also realize the synchronous adjustment of the opening size of the first ventilation hole 2, thereby realizing the precise control of the ventilation state of the transparent cover 1. The synchronization adjustment mechanism 9 includes: A fixing ring 9-1 is fixedly installed on the upper part of the support ring 3. An internal gear ring 9-2 is rotatably installed in the ring side wall of the fixing ring 9-1 through a bearing. Gears 9-3, there are several gears 9-3, which are respectively fixedly sleeved on several adjusting screws 8. The internal gear ring 9-2 is meshed with several gears 9-3. The upper end of the adjusting screw 8 passes through the fixing ring 9-1 and is fixedly equipped with an adjusting handle 9-4. The synchronous adjusting mechanism 9 can realize the synchronous control of several adjusting screws 8. It can not only make more convenient adaptation and adjustment according to the height of the seedling, but also avoid the adjusting screw 8 from being jammed due to the tilting of the support ring 3.

[0018] When using this utility model, the transparent cover 1 is placed over the seedling, and the bottom edge 5 of the support is in contact with the ground. The ground nail 12 is inserted into the ground for fixation. If it is necessary to adjust according to the height of the seedling, any one of the adjustment handles 9-4 can be rotated. The adjustment handle 9-4 drives the adjustment screw 8 connected to it to rotate. By using the meshing of several gears 9-3 with the inner gear ring 9-2, the inner gear ring 9-2 can be rotated. The several gears 9-3 and the adjustment screw 8 also rotate synchronously, changing the height between the support ring 3 and the bottom edge 5 of the support. The telescopic cover 4 also extends and retracts accordingly. When it is necessary to adjust the ventilation status, the handle 6-3 can be rotated. The handle 6-3 drives the second ventilation plate 6-5 to rotate through the rotating rod 6-2, changing the size of the ventilation opening formed by the second ventilation hole 6-4 and the third ventilation hole 6-6. During this process, the second ventilation plate 6-5 can also drive the sealing plate 6-8 to rotate inside the transparent cover 1 through the connecting rod 6-7, and simultaneously change the range of the sealing plate 6-8 blocking the first ventilation hole 2, so as to adjust the ventilation status inside the transparent cover 1.

[0019] Compared with the prior art, the beneficial effects of this utility model are: With the cooperation of the synchronous adjustment mechanism 9, the single adjustment handle 9-4 can drive all the adjustment screws 8 to raise and lower the support ring 3 and the transparent cover 1 synchronously and smoothly, realizing stepless adjustment of the overall height of the protective cover. It can accurately adapt to the height requirements of Chinese medicinal seedlings of different heights or different growth stages of the same seedling, effectively avoiding the spatial restriction and physical pressure on seedling growth caused by the fixed cover, and significantly improving the applicability of the equipment and its friendliness to crop growth. With the cooperation of the ventilation adjustment mechanism 6, the operator only needs to rotate the handle 6-3 to simultaneously change the size of the ventilation opening formed by the top and side walls of the transparent cover 1, thus achieving precise and efficient control of the ventilation environment inside the transparent cover 1. The telescopic sleeve 10 added to the outside of the adjusting screw 8 can effectively isolate the contact between the adjusting screw 8 and impurities such as mud and dust, fundamentally preventing the problem of adjustment failure caused by thread jamming, ensuring the long-term reliability and durability of the height adjustment function in harsh field environments, and reducing the maintenance frequency and failure risk. With the help of the ring-shaped reflective strip 14, the visibility of the transparent cover 1 is greatly enhanced at night or in low light conditions, which can effectively warn passing personnel and agricultural machinery and prevent damage to the protective cover and seedlings inside due to accidental collisions.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
