Description

Technical Field

[0001] This utility model relates to the field of hazelnut tree planting technology, specifically to a seedling protection device for hazelnut tree planting. Background Technology

[0002] In the process of hazelnut tree planting, the seedling stage is the key period for its growth and development. At this stage, the seedlings have slender branches and delicate leaves, and are less resistant to the external environment. They are easily affected by factors such as wind, rain, low temperature damage, and pests and diseases, which can lead to poor growth or even death. Therefore, it is necessary to provide them with a stable growing environment through protective devices.

[0003] Existing seedling protection devices mostly use transparent plastic covers with fixed ventilation holes. This may cause cold air to continuously enter the cover, causing the internal temperature to drop below the minimum threshold required for seedling growth, which can easily lead to frost damage. They are also difficult to adapt to temperature changes. In addition, rainwater can easily seep into the bottom of the cover through the ventilation holes, causing water accumulation at the roots and increasing the risk of root rot. They cannot simultaneously provide protection and ventilation. Utility Model Content

[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] To facilitate flexible adjustment of ventilation volume, combined with the attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 A seedling protection device for hazelnut trees includes a cover 1, with fixing plates 2 at each of the four corners of the cover 1, each fixing plate 2 having a fixing hole 3. It also includes ventilation holes 9 and plugs 10. A plurality of ventilation holes 9 are evenly distributed on the cover 1. A connecting frame 4 is provided at the top of the cover 1. By using a spreading assembly to move the plugs 10, the ventilation holes 9 can be either blocked or opened, achieving internal ventilation. The spreading assembly includes a disc 6 and an arc-shaped through groove 7. A rotating shaft 5 is inserted into the connecting frame 4, with the disc 6 located at the bottom of the rotating shaft 5. A plurality of arc-shaped through grooves 7 are located on the disc 6, and a handle 17 is provided at the top of the rotating shaft 5. The spreading assembly also includes L-shaped connecting rods 8. A plurality of L-shaped connecting rods 8 are slidably connected within the arc-shaped through grooves 7, and a plurality of plugs 10 are fixedly connected to one end of the corresponding L-shaped connecting rod 8. The top end of the L-shaped connecting rod 8 is slidably connected to the bottom end of the connecting frame 4.

[0026] By rotating the shaft 5, the shaft 5 drives the disc 6 to rotate synchronously. The arc-shaped groove 7 on the disc 6 slides with the L-shaped connecting rod 8, pushing the L-shaped connecting rod 8 to move along the T-shaped sliding groove 16 away from the center of the cover, thereby causing the plug 10 to disengage from the vent hole 9, thus achieving ventilation. The moving distance of the plug 10 can be flexibly adjusted according to the temperature or weather requirements to control the opening area of ​​the vent hole 9.

[0027] To facilitate locking and securing the rotating shaft 5 and prevent it from rotating freely, in conjunction with the attached... Figure 4 and attached Figure 5 The top of each L-shaped connecting rod 8 is provided with a T-shaped slider, and the bottom of the connecting frame 4 is provided with multiple T-shaped grooves 16 for use with the T-shaped sliders. The rotating shaft 5 is provided with a ratchet 11, and the top of the connecting frame 4 is provided with a damping rotating shaft 12. The damping rotating shaft 12 is provided with a pawl 13 embedded in the teeth of the ratchet 11. The top of the connecting frame 4 and the side near the pawl 13 is provided with a vertical plate 14. A spring 15 is provided between the vertical plate 14 and the pawl 13. The cover 1 and the plug 10 are both made of transparent material.

[0028] The pawl 13, under the action of the spring 15, engages between the teeth of the ratchet 11, fixing the position of the disc 6 and preventing it from rotating arbitrarily, thus affecting the normal use of the whole. The transparent cover ensures sufficient light intake to meet the photosynthetic needs of the seedlings.

[0029] In specific implementation of this utility model:

[0030] First, level the soil around the hazelnut seedling, then place the cover 1 over the outside of the seedling, so that the seedling is in the center of the cover; take 4 ground nails, pass them through the fixing holes 3 of the 4 fixing pieces 2, and hammer them into the ground to fix the cover 1.

[0031] Then, gently move the pawl 13 away from the ratchet 11 to disengage it from the ratchet teeth. Rotate the shaft 5, which drives the disc 6 to rotate synchronously. The arc-shaped groove 7 on the disc 6 slides with the L-shaped connecting rod 8, pushing the L-shaped connecting rod 8 along the T-shaped groove 16 away from the center of the cover. This causes the plug 10 to disengage from the vent hole 9, achieving ventilation. Release the pawl 13 again, and the pawl will re-engage with the ratchet teeth under the action of the spring 15, fixing the ventilation state.

[0032] During the high temperatures of summer, the ventilation holes 9 can be fully opened to achieve maximum ventilation and reduce the temperature inside the cover. During the low temperatures of spring and autumn mornings and evenings or when it rains, the ventilation holes 9 can be closed to maintain the temperature inside the cover and prevent rainwater from seeping into the bottom of the cover body 1. When the temperature rises at noon, the ventilation holes 9 can be partially opened to balance the temperature and ventilation, ensuring that the seedlings are always in a suitable growth temperature range, thus taking into account both protection and ventilation functions.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
