Technical Field
[0001] This invention relates to the fields of ecological planting technology and endangered species protection technology, specifically to a protective device for plant seedlings against predation. Background Technology
[0002] In plant conservation and ecological restoration, ensuring successful seed germination and robust seedling survival after sowing is a crucial core element, whether it's in-situ conservation and reintroduction trials of endangered species, seedling cultivation and breeding base protection of valuable economic species, or pioneer species conservation in desertification control. However, seeds and seedlings are highly vulnerable to predation by birds, rodents, and other animals, leading to planting failures and resource waste. Existing protective measures, such as physical fences, bird nets, or chemical repellents, have significant limitations: physical fences (such as simple enclosures) provide physical barriers, but are often difficult to fix or dismantle, severely hindering the light and ventilation needed for seedling growth, as well as the precision of subsequent watering and fertilization; frequent manual opening and closing of the barriers for maintenance is not only inefficient but may also damage seedlings due to improper handling; chemical repellents pose environmental pollution risks and their effects are not long-lasting. Furthermore, energy supply (such as drive motors) is a major challenge when deploying protective devices in the wild or remote areas. Therefore, there is an urgent need to develop an intelligent integrated device that can dynamically adapt to the growth needs of seedlings, achieve precise water and fertilizer management, provide effective physical and active repellency protection, and solve energy problems in the wild, so as to improve the conservation effectiveness of various high-value or vulnerable plants (such as endangered species, precious seedlings, desert pioneer plants, etc.) and the success rate of ecological restoration projects.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0033] Please see Figure 1-6 The present invention provides the following technical solutions:
[0034] A protective device for preventing predation on plant seedlings includes: a base 1, a protective cover 2 detachably mounted on the top of the base 1, a collection trough 12 in the middle of the base 1, and a protective enclosure 3 detachably connected to the bottom of the base 1 at the collection trough 12; during planting, the protective enclosure 3 is buried in the soil, and the seeds are placed inside the protective enclosure 3, which protects the seeds; a ring 4 is installed on the upper side of the base 1 and located inside the protective enclosure 3; a collection trough 10 is located in the middle of the top of the protective cover 2, and a feed inlet 11 is located in the middle of the collection trough 10, which corresponds vertically to the collection trough 12.
[0035] The protective enclosure 3 has a structure that gradually decreases in size from top to bottom. Multiple nutrient holes 17 are provided on the protective enclosure 3, and the nutrient holes 17 penetrate the inner and outer walls of the protective enclosure 3. The nutrient holes 17 can improve the absorption capacity of seeds and seedlings from the external soil while ensuring protection.
[0036] Multiple filter plates 14 are installed inside the upper part of the protective cover 2. The multiple filter plates 14 can be spliced together. A connecting plate 15 is fixedly installed at one end of the filter plate 14. The connecting plate 15 is a rectangular strip structure. The other end of the connecting plate 15 is fixedly connected to the movable plate 5. When the seeds have not germinated and broken through the soil, the filter plate 14 can block and protect the feed inlet 11 to prevent other things from entering the interior of the movable plate 5, but water or rainwater can enter to further improve the protective effect.
[0037] The bottom of the base 1 has a slot 16, which is a circular groove with threads inside. The top of the protective barrel 3 is installed inside the slot 16 by the threads. The base 1 and the protective barrel 3 can be quickly installed and removed by the threaded connection.
[0038] The flipping mechanism is installed on the protective cover 2 and is used for guiding fertilizer or water and protecting seedlings. The flipping mechanism includes several movable plates 5, movable shafts 8 and movable blocks 9. The top of the protective cover 2 is provided with several mounting slots 7. Movable plates 5 are rotatably connected in the mounting slots 7 through movable shafts 8 and movable blocks 9. The movable plates 5 can fit together to form a cylindrical structure. The rotation of the movable plates 5 can switch the state, switching between protective and deterrent functions.
[0039] Two guide plates 20 are fixedly installed on the outer wall of the movable plate 5. The guide plates 20 are rectangular plates. With the setting of the guide plates 20, when multiple movable plates 5 are unfolded upward, a guide channel is formed between the two guide plates 20 and the movable plate 5. When it rains outside, the rainwater can flow through the movable plate 5 into the inside of the collection tank 10, and then flow through the feed inlet 11 onto the seedlings. When the temperature difference between morning and evening is large, the dew on the movable plate 5 can also be collected and then flow along the slope of the movable plate 5 into the inside of the protective cover 2 to irrigate the seedlings, thus achieving the effect of automatic irrigation under multiple conditions.
[0040] The protective cover 2 has several movable openings 6 equidistantly arranged on its side wall. The movable openings 6 are located on the side wall of the protective cover 2 corresponding to the position of the movable plate 5, so that the movable plate 5 can be rotated to the outside of the protective cover 2. The protective cover 2 is equipped with a motor for driving the movable shaft 8 to rotate.
[0041] The movable plate 5 is equipped with a repulsion mechanism, which includes a mounting groove 21, a mounting shaft 22, and a flipping plate 23. The mounting groove 21 is located on the side wall of the movable plate 5, and the mounting shaft 22 is installed inside the mounting groove 21. The flipping plate 23 is rotatably connected to the mounting shaft 22. One end of the flipping plate 23 is connected to the movable plate 24 via a connecting shaft 25. Both the flipping plate 23 and the movable plate 24 are coated with a reflective coating. Through the repulsion mechanism, when the movable plate 5 is inside the protective cover 2, under the influence of gravity... The flip plate 23 and the movable plate 24 are located inside the mounting slot 21. When the movable plate 5 flips upward, the flip plate 23 and the movable plate 24 will flip out from inside the mounting slot 21 under the action of gravity. At this time, the flip plate 23 and the movable plate 24 will repel some small animals or birds by refracting light. At the same time, the movable plate 24 is rotatably connected to the flip plate 23 through the connecting shaft 25. When there is wind outside, the movable plate 24 can rotate through the connecting shaft 25 to further increase the repulsion effect on small animals.
[0042] The protective cover 2 is equipped with an energy-saving mechanism, which includes a mounting slot 3 26, a solar panel 27, and a mounting shaft 28. The mounting slot 3 26 is located on the side wall of the protective cover 2. The solar panel 27 is installed inside the mounting slot 3 26 via the mounting shaft 28. The solar panel 27 is connected to the motor that drives the movable shaft 8 on the protective cover 2 via a controller. The solar panel 27 can store electricity in the battery during the day when there is sunlight, and then supply power to the motor.
[0043] The energy-saving mechanism also includes a movable slot 29 and a transmission block 30. The movable slot 29 is located on the side wall of the protective cover 2 and connects to the interior of the movable opening 6. The transmission block 30 is a block with multiple inclined surfaces and is movably installed inside the movable slot 29 by a spring. With the setting of the energy-saving structure, when the movable plate 5 flips out from the interior of the movable opening 6, the movable plate 5 can squeeze the transmission block 30. At this time, the transmission block 30 will be squeezed and move towards the interior of the movable slot 29. Subsequently, the transmission block 30 can squeeze the solar panel 27, and the solar panel 27 will flip outward from the interior of the mounting slot 26. At this time, the solar panel 27 can be unfolded, improving the conversion efficiency of sunlight.
[0044] A positioning magnetic block 31 is embedded in the transmission block 30. An electromagnetic block 32 is embedded in the side of the mounting groove 26 near the transmission block 30. The poles of the electromagnetic block 32 and the positioning magnetic block 31 are opposite poles. An inductive switch 33 is embedded in the side wall of the protective cover 2 near the transmission block 30. The inductive switch 33 and the electromagnetic block 32 are electrically connected through a controller. With the positioning magnetic block 31 and the electromagnetic block 32, when the movable plate 5 moves inside the movable opening 6, the movable plate 5 will first pass the position of the inductive switch 33. At this time, the inductive switch 33 will be triggered, so that the inductive switch 33 can supply power to the electromagnetic block 32 through the controller, so that the electromagnetic block 32 becomes strongly magnetic. Subsequently, after the transmission block 30 moves into the interior of the movable slot 29, the position of the positioning magnetic block 31 will correspond to that of the electromagnetic block 32, and the positioning magnetic block 31 and the electromagnetic block 32 will attract each other, thus fixing the angle of the solar panel 27. At night, the movable plate 5 retracts into the interior of the protective cover 2 through the movable opening 6. At this time, the movable plate 5 will pass the position of the induction switch 33 again, and the induction switch 33 will be triggered again. At this time, the induction switch 33 will de-energize the electromagnetic block 32, and the electromagnetic block 32 will lose its magnetism. The positioning magnetic block 31 will reset under the action of the spring, and the solar panel 27 will then return to the interior of the mounting slot 26, thus achieving the effect of automatically unfolding when in use and automatically resetting after use.
[0045] An installation ring 18 is fixedly installed on the upper side of the base 1. A connecting bearing 19 is inlaid on the installation ring 18. The inner wall of the protective cover 2 is fixedly connected to the outer ring of the connecting bearing 19. The protective cover 2 is movably installed on the base 1 through the installation ring 18 and the connecting bearing 19. Since the protective cover 2 is installed on the base 1 through the installation ring 18 and the connecting bearing 19, the protective cover 2 can rotate on the base 1. This allows the movable plate 5 and the mounting groove 26 to rotate with the protective cover 2, further enhancing the deterrent effect on predators.
[0046] The working process of this invention is as follows:
[0047] When planting seeds, the protective enclosure 3 can be buried in the soil first, and then the base 1 can be installed on the protective enclosure 3. The protective cover 2 can be installed on the base 1. Multiple movable plates 5 can form a cylindrical structure at the top of the enclosure 4. At this time, the seeds can be put into the inside of the protective enclosure 3, and the seeds will fall into the inside of the protective enclosure 3. Then, the planting soil can be put into the inside of the protective enclosure 3. When watering the seeds, fertilizer or water can also be poured directly into the inside of the movable plate 5. The movable plate 5 will guide the fertilizer or water, so that the fertilizer and water fall precisely to the position of the seeds, thereby improving the accuracy of planting, fertilization and watering.
[0048] Once the seeds have grown into seedlings, the motor on the protective cover 2 drives the movable shaft 8 to rotate. The movable shaft 8 causes the movable block 9 to flip, which in turn causes the movable plate 5 to flip. At this time, multiple movable plates 5 can flip out from inside the protective cover 2 through the movable opening 6, allowing the seedlings to come into contact with the outside world. The seedlings can photosynthesize with sunlight through the movable opening 6. At the same time, the reflective coating on the opened movable plate 5 reflects light, and the flipping plate 23 can swing under the action of natural wind, which can deter some animals and prevent them from preying on the seedlings.
[0049] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
