Description

Technical Field

[0001] The present invention relates to a modular greening device based on an unmanned aerial vehicle, belonging to the technical field of plant protection unmanned aerial vehicles. Background Art

[0002] With the increasing frequency of construction activities at transmission line tower bases, the greening work in the construction disturbance areas becomes particularly important. The current situation of greening in the construction disturbance areas of transmission line tower bases faces many challenges. Due to the special geographical location, it is difficult and costly to transport ecological restoration materials. At the same time, the project area often lacks water sources and power supplies, which pose great obstacles to vegetation construction and subsequent maintenance. In addition, the excavation of the tower base destroys the original vegetation and soil structure, resulting in a serious decline in soil fertility and water retention function. Due to the complex terrain and harsh construction conditions, the greening work often requires a large amount of manpower, material resources and financial resources. Ecological restoration is a long-term process that requires continuous monitoring and maintenance, which also increases the difficulty and cost of the greening work. Some special environmental factors, such as climate, soil, vegetation type, etc., will also affect the greening work. Therefore, the greening work in the construction disturbance areas of transmission line tower bases is extremely difficult;

[0003] Currently, the greening means in the construction disturbance areas of transmission line tower bases mainly rely on manual seeding, which is widely used for its low cost and easy operation. Although this method is simple and direct, it also has limitations. On the one hand, due to the complex and changeable mountain terrain, it is difficult to ensure the uniformity of grass seed distribution during manual seeding, thus affecting the vegetation restoration effect. On the other hand, manual seeding of grass seeds has high requirements for soil conditions. If the soil is poor or the water content is insufficient, it will directly affect the germination rate and survival rate of the grass seeds.

[0004] Unmanned aerial vehicle technology has shown significant application value in the agricultural field, and its flexibility and high efficiency provide innovative solutions for modern agriculture. In plant protection operations, unmanned aerial vehicles equipped with spraying systems can achieve directional spraying; while in the sowing link, large-scale aerial sowing operations can be carried out through sowing equipment.

[0005] However, the aerial sowing technology has significant defects: when the seeds are directly scattered on the ground surface, due to the lack of an effective fixing mechanism, they are extremely vulnerable to the action of wind and are prone to displacement, resulting in uneven sowing density, etc. The bare sowing not only reduces the seed germination rate but also may affect the vegetation restoration effect. Summary of the Invention

[0006] The purpose of the present invention is to provide a modular greening device based on an unmanned aerial vehicle to solve the problems raised in the above background art.

[0007] The technical solution of the present invention is as follows:

[0009] The seeding module includes a seed storage box, a sandwich layer, seeding needles and a return spring. The sandwich layer is arranged directly below the seed storage box, and the upper end of the seeding needle penetrates through the sandwich layer into the interior of the seed storage box;

[0010] The seeding needles slide up and down in the sandwich layer. The seeding needles are in the shape of nails, and a seeding channel inlet is arranged at the upper end of the seeding needles.

[0021] Preferably, the lower end of the seeding needle is in a tip structure, and a seeding channel outlet is arranged on the side wall of the lower end of the seeding needle. The seeding channel outlet at the lower end of the seeding needle is driven by the return spring to tend to be exposed outside the sandwich layer;

[0022] When the seeding needle touches the ground, the seeding needle moves upward so that the outlet of the seeding channel moves to be hidden in the sandwich layer.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1:

[0041] A modular greening device based on a drone, as Figures 1 - 5 shown:

[0042] The drone can be a rotary-wing drone.

[0043] The drone is detachably connected with a rotary spraying module, a rotary drilling module, a water supply module and a seeding module. As Figure 1 shown in the figure, it is a schematic diagram of four groups of rotary spraying modules mounted on the four rotors of the drone.

[0044] A liquid delivery pipeline is provided on the drone;

[0045] As Figure 2 shown, the rotary spraying module includes a spraying ring 1-1 and a support frame 1-3. Spraying holes are arranged inside the spraying ring 1-1, and a spraying delivery pipe is arranged inside the support frame 1-3. The spraying ring 1-1 is a hollow ring, and a number of spraying holes are uniformly arranged at an angle of 45° obliquely downward inside the spraying ring 1-1. The support frame 1-3 is in a "V" shape, and one end of the spraying delivery pipe arranged inside the support frame 1-3 is connected to the inner cavity of the spraying ring 1-1, and the other end of the spraying delivery pipe is connected to the inner interface 1-5 of the rotary spraying module. The inner interface 1-5 of the rotary spraying module is fixed in a concave cylindrical shape at the narrower end of the support frame 1-3, and connecting threads are arranged on the inner wall of the inner interface 1-5 of the rotary spraying module.

[0046] The rotary spraying module is detachably connected to the liquid delivery pipeline of the drone through the inner interface 1-5 of the rotary spraying module by threads, and the rotor 1-2 of the drone is located at the center of each spraying ring 1-1. The rotation of the rotor 1-2 provides the flight power for the drone to rise / fall on the one hand, and on the other hand, the spraying water vapor is atomized through the rotating airflow to achieve uniform irrigation.

[0047] As Figure 3 shown, the rotary drilling module includes a spiral drill bit 2-2 and an external interface 2-1 of the rotary drilling module; the spiral drill bit 2-2 is spiral-shaped, and the cutting edge spirally narrows inward from top to bottom. The spiral drill bit 2-2 is wider at the top and narrower at the bottom, and is overall in the shape of a snail. The spiral cutting edge can effectively till and cover the soil. The external interface 2-1 of the rotary drilling module is in a convex cylindrical shape, and connecting threads are arranged on the annular outer wall. The spiral drill bit 2-2 is detachably connected to the lower end of the rotor 1-2 of the drone through the external interface 2-1 of the rotary drilling module by threads. A non-contact coupler can be arranged between the lower end of the rotor 1-2 of the drone or between the spiral drill bit 2-2 and the external interface 2-1 of the rotary drilling module. The non-contact coupler can adopt a magnetic coupler;

[0048] The rotor 1-2 of the drone rotates to provide rotary tillage power for the auger bit 2-2 at the same time. During the process of the auger bit 2-2 drilling into the soil, a non-contact coupler is used to prevent the sudden stop of the auger bit 2-2 from affecting the flight of the drone.

[0049] The rotary drilling module can drill holes of a certain depth in the soil, which is convenient for subsequent sowing of seeds in the holes to avoid being blown away by the wind.

[0050] As Figure 4 shown, the water supply module includes a water supply pipe 3-2 and a water storage tank 3-3. One end of the water supply pipe 3-2 is fixedly connected to the water storage tank 3-3, and the other end of the water supply pipe 3-2 is provided with a water supply interface 3-1 of the water supply module. The water supply pipe 3-2 is detachably threadedly connected to the liquid delivery pipe of the drone through the water supply interface 3-1 of the water supply module;

[0051] The water supply pipe 3-2 is a hollow circular pipe, and a water pump is provided at the connection between the water storage tank 3-3 and the water supply pipe 3-2 to transport the water source from the water storage tank 3-3 to the rotor spraying module. The inner wall of the water storage tank 3-3 is in a "U" shape to quickly converge the water source, and its external features effectively relieve the load pressure of the drone.

[0052] As Figure 5 shown, the sowing module includes a seed storage box 4-2, a sandwich layer 4-3 and sowing needles 4-4;

[0053] The seed storage box 4-2 is a hollow cylindrical container with a bowl-shaped inner side. Affected by gravity, the seeds can quickly converge to the sowing channel.

[0054] The sandwich layer 4-3 is a hollow straight pipe structure fixed directly below the seed storage box 4-2. The sowing needles 4-4 slide linearly up and down inside the sandwich layer 4-3 in a mating manner. The sowing needles 4-4 penetrate through the sandwich layer 4-3 into the interior of the seed storage box 4-2, and a return spring is provided between the sowing needles 4-4 and the seed storage box 4-2;

[0055] A channel is provided between the upper and lower ends of the sowing needle 4-4. The sowing needle 4-4 is in the shape of a nail, and the upper end of the sowing needle 4-4 with a cover plate is located inside the seed storage box 4-2. A sowing channel inlet is provided on the side wall of the upper end of the sowing needle 4-4, and the sowing channel inlet is relatively located below the cover plate. The channel penetrates from the sowing channel inlet to the bottom of the sowing needle 4-4.

[0056] Under the action of the return spring, without external force, the cover plate at the upper end of the sowing needle 4-4 fits against the bottom plate of the seed storage box 4-2. At this time, the inlet of the sowing channel is hidden inside the interlayer 4-3 and is in a static state. When the lower end of the sowing needle 4-4 touches the ground, the sowing needle 4-4 moves upward, and the inlet of the sowing channel appears to communicate with the inner cavity of the seed storage box 4-2. Seeds enter the channel of the sowing needle 4-4 through the inlet of the sowing channel and fall out from its bottom under the action of gravity to be planted in the soil, being in the sowing state.

[0057] A sowing module external connection interface 4-1 is provided at the top of the seed storage box 4-2. Through the sowing module external connection interface 4-1, seeds can be loaded into the seed storage box 4-2, and the seed storage box 4-2 can also be detachably threadedly connected to the drone through the sowing module external connection interface 4-1.

[0058] The ground can be dug into holes of a certain depth by the rotary drilling module first, and then the sowing module can sprinkle seeds into the holes. During the process of the sowing needle 4-4 being pulled out of the holes, the rotor 1-2 of the drone can blow the nearby soil around, so that a certain amount of soil can cover the holes, further preventing the seeds from flowing randomly.

[0059] Embodiment 2: It includes all the contents of Embodiment 1, the difference is that, as Figure 6 :

[0060] The lower end of the sowing needle 4-4 is in a pointed structure, which is convenient for inserting into the soil.

[0061] The sowing channel outlet at the lower end of the channel is arranged on the side wall of the lower end of the sowing needle 4-4. When the lower end of the sowing needle 4-4 touches the ground, the sowing needle 4-4 moves upward relative to the interlayer 4-3, and the inlet of the sowing channel appears to communicate with the inner cavity of the seed storage box 4-2. At the same time, the sowing channel outlet moves upward relative to the interlayer 4-3 and is hidden by the interlayer 4-3. At this time, the seeds in the seed storage box 4-2 are quantitatively temporarily stored in the channel of the sowing needle 4-4 through the inlet of the sowing channel. The drone is controlled to slowly rise. At this time, under the action of the return spring, the sowing needle 4-4 is first pushed to move downward relative to the interlayer 4-3, so that the sowing channel outlet at the lower end of the sowing needle 4-4 is exposed, and thus the quantitatively seeds in the channel of the sowing needle 4-4 can flow out through the sowing channel outlet.

[0062] The above design not only realizes the quantitative delivery of seeds, but also can prevent the sowing channel from being blocked by soil when the lower end of the sowing needle 4-4 is inserted into the soil.

[0063] The above are only the embodiments of the present invention, and do not limit the scope of the patent of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
