Description

Technical Field

[0001] This utility model relates to the field of seed harvesting, and in particular to a device for collecting seeds from natural plant communities. Background Technology

[0002] Native species are preferred during ecological restoration, as they possess good adaptability and are unlikely to cause biological invasions or extinction due to maladaptation to the local environment. Using seeds from natural communities to restore degraded ecosystems acts as a "seed transporter," accelerating the natural restoration process while ensuring the biodiversity and ecological adaptability of the restored vegetation community. However, seed collection from natural vegetation communities is quite challenging. While there are many seed collection devices for specific plant populations or economic forest trees, few are suitable for seed collection in natural communities. This is partly due to the complexity of vegetation types in natural communities, requiring highly versatile seed collection equipment; and partly due to the complex terrain and dense vegetation in the wild, making collection operations difficult with ordinary equipment. Utility Model Content

[0003] The main objective of this invention is to provide a natural plant community seed collection device that can be applied to various terrains to efficiently collect seeds from various vegetation communities. The collected natural seeds are used as a material basis for the restoration of degraded vegetation communities, simulating the surrounding vegetation environment to construct vegetation communities. This ensures the species diversity and ecological adaptability of the vegetation communities during the restoration process, thereby achieving rapid and effective restoration.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a natural plant community seed collection device, wherein a collection box is provided at the bottom of the drone, the bottom of the collection box is connected to a collection cover extending out of the range of the drone's fan blades, and a camera is also provided at the bottom of the collection box, facing the direction of the collection cover;

[0005] The collection box is equipped with a motor, and the motor output end is equipped with an impeller for ventilation. The collection box is also equipped with a second screen plate, which divides the collection box into upper and lower chambers. The motor and impeller are located in the upper chamber, and the lower chamber is connected to the collection cover through the collection inner pipe.

[0006] In the preferred embodiment, the lower part of the collection box is provided with a vertical tube, the lower end of which is hinged to one end of the collection rod, and the hinge position is provided with damping. The other end of the collection rod extends out of the range of the UAV fan blades and is connected to the collection cover.

[0007] In the preferred embodiment, both the vertical tube and the collecting rod are hollow structures. The tail of the collecting hood is connected to the lower chamber of the collecting box through an inner collecting tube, which is located inside the vertical tube and the collecting rod.

[0008] In the preferred embodiment, the collection hood has a horn-shaped opening structure, and a first mesh plate is provided at the opening of the collection hood, with the mesh plate having a hole diameter of 15-20mm.

[0009] In the preferred embodiment, a collection net bag is also provided inside the lower chamber of the collection box, and the opening of the collection net bag is connected to the end of the collection inner tube by a snap ring or by a thread.

[0010] In the preferred embodiment, a material retrieval door is also provided on one side of the lower chamber of the collection box. The material retrieval door is snapped into the collection box around its perimeter and connected to the tail of the collection net bag.

[0011] In the preferred embodiment, the top of the upper chamber of the collection box is provided with multiple exhaust ports, and the outer ring of the motor is provided with a conical guide surface, which guides the airflow of the impeller to the multiple exhaust ports and discharges it.

[0012] In the preferred embodiment, a filter screen is installed at the exhaust port.

Detailed Implementation

[0022] like Figure 1-3 As shown, a natural plant community seed collection device is provided. The drone 1 is equipped with a collection box 4 at the bottom. The bottom of the collection box 4 is connected to the collection cover 7 that extends out of the range of the drone 1's blades. The bottom of the collection box 4 is also equipped with a camera 3, which is set towards the collection cover 7.

[0023] The collection box 4 is equipped with a motor 14, and the output end of the motor 14 is equipped with an exhaust impeller 13. The collection box 4 is also equipped with a second mesh plate 12, which divides the collection box 4 into upper and lower chambers. The motor 14 and the impeller 13 are located in the upper chamber, and the lower chamber is connected to the collection cover 7 through the collection inner pipe 8.

[0024] In operation, the drone 1 flies along a pre-set "S-shaped" trajectory, covering the target vegetation area and collecting plant seeds using the collection hood 7 below. The motor 14 drives the impeller 13 to generate suction, drawing the seeds through the collection hood 7 and inner collection tube 8 into the lower chamber of the collection box 4 for centralized storage. Simultaneously, the camera 3 monitors the operation of the collection hood 7 area in real time, ensuring the effectiveness and accuracy of the collection process. This device is suitable for various complex terrains and can efficiently collect seeds from multiple vegetation types without direct human intervention.

[0025] Non-contact seed collection via drone 1 minimizes disturbance to natural vegetation communities while ensuring the randomness and diversity of seed collection. The layered design and ventilation system within the collection box 4 effectively separate and preserve seeds, improving collection efficiency. Furthermore, this equipment can be widely applied in scientific research fields such as biodiversity conservation, vegetation degradation diagnosis, and ecological restoration. It can also be integrated with existing engineering technologies for slope ecological protection and mine ecological restoration, ensuring species diversity and ecological adaptability, and avoiding disasters caused by indiscriminate introduction of species due to biological invasion or environmental unsuitability.

[0026] In the preferred embodiment, the lower part of the collection box 4 is provided with a vertical tube 402, the lower end of the vertical tube 402 is hinged to one end of the collection rod 6, and the hinge position is provided with damping. The other end of the collection rod 6 extends out of the fan blade range of the UAV 1 and is connected to the collection cover 7.

[0027] The collecting rod 6 and the vertical tube 402 are hinged and have a damping design, allowing the operator to adjust the posture of the collecting hood 7 as needed and maintain its stable operation, avoiding angular deviation caused by airflow or vibration. Simultaneously, driven by the impeller 13 by the motor 14, the seeds pass through the collecting hood 7 and the inner collecting tube 8 into the lower chamber inside the collecting box 4 for storage, completing an efficient and directional seed collection process.

[0028] In the preferred embodiment, both the vertical tube 402 and the collecting rod 6 are hollow structures. The tail of the collecting cover 7 is connected to the lower chamber of the collecting box 4 through the inner collecting tube 8, which is located inside the vertical tube 402 and the collecting rod 6.

[0029] The seeds are drawn in and transported through the inner collection tube 8, located inside the vertical tube 402 and the collection rod 6, to the lower chamber of the collection box 4 for centralized storage. This structural design avoids interference from external airflow, improving seed transport efficiency and collection density.

[0030] The inner collecting tube 8 is placed inside the vertical tube 402 and the collecting rod 6. Its hollow structure enables closed-loop seed transport, reducing wind resistance and seed loss, and enhancing collection density and efficiency.

[0031] In the preferred embodiment, the collecting hood 7 has a funnel-shaped opening structure, and a first mesh plate 701 with a aperture of 15-20mm is provided at the opening of the collecting hood 7. The collecting hood 7 expands the collection entrance range through its funnel-shaped structure, allowing more seeds to be sucked in by the suction. The motor 14 drives the impeller 13 to generate negative pressure, and the seeds enter the collecting hood 7 under the airflow. Larger impurities are filtered out by the first mesh plate 701 to prevent blockage of the pipes; seeds of suitable size are transported through the inner collecting tube 8 to the lower chamber inside the collecting box 4 for centralized storage.

[0032] The collection hood 7, with its horn-shaped opening structure, can effectively improve the coverage area and feeding efficiency of seed collection. At the same time, the reasonable aperture design of the first screen plate 701 can filter out large particles of impurities, retain the suitable range of seed particle sizes for collection, and improve collection accuracy and subsequent processing efficiency.

[0033] In the preferred embodiment, a collection net bag 10 is also provided inside the lower chamber of the collection box 4. The opening of the collection net bag 10 is snapped or threaded to the end of the collection inner tube 8 through a retaining ring 9.

[0034] The lower chamber of the collection box 4 is also provided with a material retrieval door 11. The material retrieval door 11 is engaged with the collection box 4 around its perimeter and is connected to the tail of the collection net bag 10.

[0035] After being filtered by the collection cover 7 and the first mesh plate 701, the seeds are transported through the inner collection tube 8 to the inside of the collection mesh bag 10 for centralized storage. After collection, the collection mesh bag 10 is removed as a whole by opening the material handling door 11, realizing the rapid transfer and processing of seeds and avoiding seed residue or cross-contamination inside the collection box 4.

[0036] By setting up a detachable collection net bag 10 and a snap-fit ​​material gate 11, the efficiency of seed collection and processing is improved, making it easier to quickly replace and clean the seed, and reducing equipment maintenance time.

[0037] In the preferred embodiment, the upper chamber of the collection box 4 is provided with multiple exhaust ports 15, and the outer ring of the motor 14 is provided with a conical guide surface 16. The guide surface 16 guides the airflow from the impeller 13 to the multiple exhaust ports 15 and discharges it. A filter screen is provided at the exhaust port 15. During the exhaust process, after the air enters the upper chamber, it is pressurized by the impeller 13 and guided by the guide surface 16 to the exhaust port 15 for discharge. During the exhaust process, dust and other particles are intercepted by the filter screen to prevent environmental pollution and blockage of the channel.

[0038] By setting multiple exhaust ports 15 and conical guide surfaces 16, the airflow path is optimized, the working efficiency of the impeller 13 is improved, and the overall ventilation capacity is enhanced, thereby increasing the seed collection speed and density.

[0039] The filter design at the exhaust port 15 effectively prevents dust and debris from being discharged with the airflow, reducing the risk of environmental pollution. It also protects the motor 14 from dust intrusion, extending the equipment's lifespan. This structure enhances the stability and environmental performance of the equipment, making it suitable for seed collection tasks requiring long-term continuous operation in complex field environments.

[0040] In the preferred embodiment, the second mesh plate 12 has a concave structure, with the concave facet surrounding the impeller 13 and maintaining a distance between them. The aperture of the second mesh plate 12 is 3-4 mm. The motor 14 drives the impeller 13 to generate a suction effect, causing the seeds to be transported through the collection hood 7 and the inner collection tube 8 into the collection mesh bag 10. During this process, air is drawn in along with the seeds and filtered through the second mesh plate 12. This concave structure effectively blocks larger particles of impurities from entering the upper chamber while avoiding contact interference with the impeller 13, ensuring smooth airflow and stable operation of the impeller 13.

[0041] The second mesh plate 12 adopts a concave structure design, conforming to the shape of the impeller 13 while maintaining a safe distance. This enhances the filtration effect while avoiding obstruction of the impeller 13's operation, thus improving the stability of the overall airflow system. The pore size is set at 3-4mm, effectively preventing weeds, debris, and other foreign objects from entering the upper chamber, protecting the motor 14 from damage and extending the equipment's service life. This structure improves cleanliness and safety during the collection process, making it suitable for long-term, high-efficiency operation in complex vegetation environments.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
