Description

Technical Field

[0001] This invention relates to the field of warehousing and transportation technology, and specifically to a drone-based transportation and warehousing system. Background Technology

[0002] Litsea cubeba fruit is rich in citral (60%-90%). The fruit and seeds of Litsea cubeba can not only be used to extract fragrances, but also possess various medicinal values ​​such as antibacterial and anti-inflammatory properties. It has extremely high development value in the fields of fragrance, food, medicine, and biological control. The fruit of Litsea cubeba is nearly spherical, about 4-6 mm in diameter, with a thin and brittle outer skin. When ripe, the high oil content makes the peel even more fragile, and it may crack under slight external impact.

[0003] Currently, most Litsea cubeba is grown in mountains, leading to transportation difficulties. To improve transportation efficiency, drone transportation has emerged as a technology that can greatly solve transportation problems. Transportation warehousing is also used in conjunction with drones. However, during the harvesting process, leaves are easily mixed into the containers used to transport the Litsea cubeba fruit. These leaves are then transported by drone to the transportation warehousing facility for initial sorting and packaging (without separating the leaves), followed by further cleaning and processing at a sorting center, resulting in wasted transportation capacity. Furthermore, the fruit peel is fragile and easily broken during drone unloading, leading to high natural losses during drone transportation. Therefore, a drone transportation warehousing system that can pre-sort Litsea cubeba fruit and reduce natural losses is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drone-based transportation and storage system that can sort Litsea cubeba in advance and reduce the natural loss of Litsea cubeba.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A drone-based transportation and warehousing system includes a transportation module and a warehousing module;

[0007] The storage module includes a storage bin, a fan, and an annular air guide assembly; an air inlet is provided at the bottom of the side wall of the storage bin, and the fan is located outside the storage bin and connected to the air inlet; the top of the storage bin is open, and the air guide assembly is connected to the edge of the open to guide the airflow blown out of the storage bin according to the air guide direction of the air guide assembly to obtain a deflected airflow area;

[0008] The transport module includes a drone, a sling, and a lifting container. The lifting container is detachably suspended on the belly of the drone via the sling. The drone's unloading position is directly above the opening and outside the deflecting airflow area. The minimum length of the sling is the length of the line connecting the drone's hovering unloading position to the lifting container when it is inside the storage bin. The maximum cross-sectional area of ​​the lifting container is less than or equal to half the maximum area of ​​the opening. The bottom of the lifting container has a release port.

[0009] When the drone flies, the deflected airflow area is set as a no-fly zone. When the drone flies to the unloading position, the fan works to continuously send air into the storage barrel through the air inlet. The drone sends the lifting container through the air guide component into the opening and keeps it in a hovering state. Then the release port is opened to feed the material. The airflow generated by the fan slows down the fed material and blows out the impurities mixed in with the material along the deflected airflow area. After the feeding is completed, the release port is closed, and the drone flies vertically upward to carry the lifting container away from the storage barrel.

[0010] Preferably, the opening is rectangular in shape;

[0011] The air guiding assembly includes a first air guiding plate, a second air guiding plate, a first connecting plate, and a second connecting plate, which are respectively connected to the four edges of the opening.

[0012] The first air guide plate and the second air guide plate are arranged in parallel. The two ends of the first connecting plate are respectively connected to the first air guide plate and the second air guide plate, and the two ends of the second connecting plate are respectively connected to the first air guide plate and the second air guide plate.

[0013] Preferably, the angle between the first air guide plate and the vertical direction of the storage tank is 30°-45°.

[0014] Preferably, the edges of the first air guide plate, the second air guide plate, the first connecting plate, and the second connecting plate are rounded and then polished.

[0015] Preferably, the air guide assembly is detachably connected to the edge of the opening.

[0016] Preferably, a plurality of NFC tags are disposed within the opening;

[0017] The bottom of the hoisting container is equipped with an electric valve, a battery, and an NFC reader. The battery is electrically connected to both the electric valve and the NFC reader. The electric valve is located at the release port. The battery and the NFC reader are surrounded by a protective shell.

[0018] When the NFC reader reads the NFC tag, the electric valve opens to open the release port.

[0019] When the NFC reader fails to read the NFC tag, the electric valve closes to shut off the release port.

[0020] Preferably, reinforcing ribs are also provided on the outer peripheral surface of the storage hopper.

[0021] Preferably, a filter screen is provided on the air inlet.

[0022] Preferably, the storage hopper includes an upper hopper body and a lower hopper body, and an air inlet is provided at the bottom of the side wall of the lower hopper body.

[0023] Preferably, the lower barrel is funnel-shaped, and a discharge port is provided at the bottom of the lower barrel, with a discharge valve provided on the discharge port.

[0024] The beneficial effects of this invention are as follows: By setting up a fan and an annular air guide assembly, and with an air inlet located at the bottom of the side wall of the storage hopper, the upward airflow generated by the fan can slow down the tipping of the Litsea cubeba, preventing the thin-skinned Litsea cubeba from colliding and breaking during the tipping process by the drone, thereby reducing natural losses—this is the first effect. Furthermore, the airflow generated by the air guide assembly can be redirected along the direction of the air guide assembly, preventing it from blowing vertically upwards and affecting the drone—this is the second effect. Additionally, the generated airflow can also carry away Litsea cubeba leaves or dust. This achieves preliminary impurity removal and filtration, the third effect. Furthermore, the blown-out leaves or dust from the Litsea cubeba can return to the planting site or nearby areas, achieving degradation and resource reuse, similar to fallen leaves returning to their roots, realizing a natural cycle. The airflow also provides preliminary drying and cooling for the Litsea cubeba, preventing rotting due to excessive humidity or temperature, the fourth effect. Additionally, since the drone also generates a downward airflow, it can combine with the airflow in the deflection area, making it easier for the airflow in the deflection area to deflect outwards, thus eliminating the need for excessively tilted air guide components that would affect the convenience of loading and unloading. The maximum cross-sectional area of ​​the lifting container is less than or equal to half the maximum open area, facilitating easy entry into the storage bin, improving efficiency, and preventing the lifting container from blocking the air guide components, thus avoiding airflow difficulties and the inability to form airflow.

[0025] Because the bottom of the hoisting container has a release port, the release of Litsea cubeba is rapid, meaning a large amount of Litsea cubeba is discharged quickly. If the wind force generated by the fan is not strong enough, it will not be able to slow down a large amount of Litsea cubeba at the same time. At the same time, the wind speed of the airflow generated by the fan and discharged through the air guide component is greater than the downwind speed generated by the drone hovering at the unloading position, which can ensure that the Litsea cubeba blades can be discharged smoothly.

[0029] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please refer to Figure 1 as well as Figure 2 A drone 11 for transport and storage includes a transport module 1 and a storage module 2;

[0031] The storage module 2 includes a storage bin 21, a fan 22, and an annular air guide assembly 23. An air inlet 24 is provided at the bottom of the side wall of the storage bin 21. The fan 22 is located outside the storage bin 21 and connected to the air inlet 24. The top of the storage bin 21 is open. The air guide assembly 23 is connected to the edge of the open opening and guides the airflow blown out of the storage bin 21 according to the air guide direction of the air guide assembly 23 to obtain a deflected airflow area 25.

[0032] The transport module 1 includes a drone 11, a hoisting rope 12, and a hoisting container 13. The hoisting container 13 is detachably hoisted onto the belly of the drone 11 via the hoisting rope 12. The drone 11 is positioned directly above the open end and outside the deflecting airflow area 25. The minimum length of the hoisting rope 12 is the length of the line connecting the drone 11 at its unloading position to the hoisting container 13 when it is inside the storage bin 21. The maximum cross-sectional area of ​​the hoisting container 13 is less than or equal to half the maximum area of ​​the open end. The bottom of the hoisting container 13 has a release port 14.

[0033] When the drone 11 flies, the deflecting airflow area 25 is set as a no-fly zone. When the drone 11 flies to the unloading position, the fan 22 works to continuously send air into the storage tank 21 through the air inlet 24. The drone 11 sends the hoisting container 13 through the air guide assembly 23 into the opening and keeps it in a hovering state. Then, the release port 14 is opened to feed materials. The airflow generated by the fan 22 decelerates the fed materials and blows out the impurities mixed in with the materials along the deflecting airflow area 25. After feeding is completed, the release port 14 is closed, and the drone 11 flies vertically upward to carry the hoisting container 13 away from the storage tank 21.

[0034] As described above, by setting up a fan 22 and an annular air guide assembly 23, and with an air inlet 24 located at the bottom of the side wall of the storage bin 21, the upward airflow generated by the fan 22 can slow down the tipping of the Litsea cubeba, preventing the thin-skinned Litsea cubeba from colliding and breaking during the tipping of the drone 11, thus reducing natural losses—this is the first effect. Furthermore, the air guide assembly 23 allows the generated airflow to be redirected along its direction, preventing it from blowing vertically upwards and affecting the drone 11. The second effect is that the generated airflow can also carry away the leaves or dust of the Litsea cubeba, achieving preliminary impurity removal and filtration, which is the third effect. The airflow can also perform preliminary drying and cooling of the Litsea cubeba, preventing it from rotting due to excessive humidity or temperature, which is the fourth effect. Furthermore, since the drone 11 also generates a downward airflow, it can create a resultant force with the airflow in the deflection airflow area 25, making it easier for the airflow in the deflection airflow area 25 to deflect outward, thus avoiding the need to set the air guide component 23 too tilted, which would affect the convenience of loading and unloading. The maximum cross-sectional area of ​​the hoisting container 13 is less than or equal to half of the maximum open area, which can facilitate entry into the storage bin 21, improve efficiency, and also prevent the hoisting container 13 from blocking the air guide component 23, causing difficulty in airflow and thus preventing the formation of airflow.

[0035] Furthermore, the opening is rectangular in shape;

[0036] The air guide assembly 23 includes a first air guide plate 231, a second air guide plate 232, a first connecting plate 233, and a second connecting plate 234. The first air guide plate 231, the second air guide plate 232, the first connecting plate 233, and the second connecting plate 234 are respectively connected to the four edges of the opening.

[0037] The first air guide plate 231 and the second air guide plate 232 are arranged in parallel. The two ends of the first connecting plate 233 are respectively connected to the first air guide plate 231 and the second air guide plate 232, and the two ends of the second connecting plate 234 are respectively connected to the first air guide plate 231 and the second air guide plate 232.

[0038] Furthermore, the angle between the first air guide plate 231 and the storage tank 21 in the vertical direction is 30°-45°.

[0039] As can be seen from the above description, the angle between the first air guide plate 231 and the storage bucket 21 in the vertical direction is 30°-45°, so as to avoid the angle being too large and blocking the opening.

[0040] Furthermore, the edges of the first air guide plate 231, the second air guide plate 232, the first connecting plate 233, and the second connecting plate 234 are rounded and then polished.

[0041] As can be seen from the above description, rounding the corners before polishing prevents the sharp edges from scratching the hoisting container 13.

[0042] Furthermore, the air guide assembly 23 is detachably connected to the edge of the opening.

[0043] As can be seen from the above description, the detachable air guide assembly 23 facilitates the disassembly and transportation of the storage module 2.

[0044] Furthermore, a number of NFC tags 235 are provided inside the opening;

[0045] The bottom of the hoisting container 13 is equipped with an electric valve 131, a battery 132, and an NFC card reader 133. The battery 132 is electrically connected to the electric valve 131 and the NFC card reader 133 respectively. The electric valve 131 is located on the release port 14. The battery 132 and the NFC card reader 133 are surrounded by protective shells.

[0046] When the NFC reader 133 reads the NFC tag 235, the electric valve 131 opens to open the release port 14.

[0047] When the NFC reader 133 fails to read the NFC tag 235, the electric valve 131 closes, thereby closing the release port 14.

[0048] As described above, the use of NFC facilitates near-field sensing and enables automatic opening and closing of the release port 14 for unloading. The protective casing prevents damage from impacts during use.

[0049] Furthermore, reinforcing ribs 236 are also provided on the outer peripheral surface of the storage hopper 21.

[0050] As can be seen from the above description, by setting the reinforcing rib 236, a better load-bearing effect can be achieved in the storage hopper 21.

[0051] Furthermore, a filter screen is provided on the air inlet 24.

[0052] As can be seen from the above description, the filter screen can prevent Litsea cubeba from entering the fan 22 and causing an accident.

[0053] Furthermore, the storage hopper 21 includes an upper hopper body 237 and a lower hopper body 238, and an air inlet 24 is provided at the bottom of the side wall of the lower hopper body 238.

[0054] Furthermore, the lower barrel body 238 is funnel-shaped, and a discharge port 239 is provided at the bottom of the lower barrel body 238, with a discharge valve provided on the discharge port.

[0055] As can be seen from the above description, the funnel-shaped lower barrel 238 facilitates material discharge and packaging, while the funnel-shaped lower barrel 238 also facilitates the upward blowing of airflow, ensuring the deceleration effect of the airflow on the Litsea cubeba.

[0065] The edges of the first air guide plate 231, the second air guide plate 232, the first connecting plate 233, and the second connecting plate 234 are rounded and then polished.
