Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural drones, and particularly relates to a seed capsule sowing device. Background Art

[0002] As a carrier, the seed capsule places seeds, water-retaining agents, fertilizers, etc. in a degradable capsule shell. In the desert, the traditional planting method is manual sowing.

Moreover, manual sowing is not suitable for large-area sowing operations. When manual sowing is carried out under complex terrain conditions, such as sowing in an area with a certain slope, the sowing efficiency will be further reduced. Content of the Utility Model

[0032] (III) Beneficial effects

[0033] Compared with the prior art, the beneficial effects of the utility model are:

[0034] 1. In the present utility model, the use of drones can quickly spread seed capsules to the target area, and can be used for large-scale seeding operations, greatly improving seeding efficiency.

[0035] 2. In the utility model, the wind blown out by the fan blows the rolling seed capsule, providing a thrust for the seed capsule to move along the guide surface. During the movement, the seed capsule can be adjusted from a horizontal state to a vertical state with the previous state by the provided guide block, ensuring that after being ejected from the discharge port, the impact of wind resistance on the seed capsule is reduced. The fan makes the seed capsule be ejected from the discharge port with a certain acceleration, so that after the seed capsule contacts the soil, the seed capsule still has a part of inertia and pierces into the soil, thereby fixing the seed capsule to prevent the seed capsule from rolling to other places due to the influence of wind after falling to the ground.

[0036] III. In the present utility model, the second driving motor drives the second driving gear to rotate through the output shaft. Under the meshing action with the toothed plate, the feeding box will move in the sliding groove through the slide rail, thereby adjusting the angle of the discharge port. Compared with shooting the seed capsule vertically onto the slope, when the seed capsule is shot onto the slope at a certain inclination angle, the contact area between the end of the seed capsule and the slope will be larger, so that the seed capsule can more easily penetrate into the soil, effectively preventing side slip.

[0037] IV. In the present utility model, during the counterclockwise rotation of the baffle of the material guiding cavity, the air supply cavity will be blocked, and the gas inside the air supply cavity can be ensured to be discharged in time through the provided air leakage grooves.

[0038] V. In the present utility model, after the baffle of the material guiding cavity and the air leakage baffle are reset, the first magnet is re-attracted to the baffle of the material guiding cavity, and the second magnet is re-attracted to the air leakage baffle, preventing the baffle of the material guiding cavity and the air leakage baffle from automatically drooping and opening due to their own gravity.

[0039] VI. In the present utility model, the wind speed is detected by the wind resistance detector and fed back to the drone in a timely manner. When the wind resistance received is greater, the flight height of the drone will be correspondingly reduced, thereby shortening the distance between the discharge port and the ground, shortening the travel of the seed capsule, and reducing the influence of the wind resistance on the seed capsule.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0054] Embodiment 1

[0055] As Figures 1 - 12 shown, a seed capsule sowing device includes an unmanned aerial vehicle 1, a docking rack 2 is fixedly connected to the bottom of the unmanned aerial vehicle 1, a fan 3 is installed on one side of the unmanned aerial vehicle 1, a feeding box 4 is slidably connected to the docking rack 2, a material guiding air cavity 5 is fixedly installed at the bottom of the feeding box 4, the feeding box 4 is communicated with the material guiding air cavity 5, one end of the material guiding air cavity 5 is open and the other end is communicated with the air outlet of the fan 3;

[0056] The feeding box 4 and the material guiding air cavity 5 are provided with the same discharging structure on the same side;

[0057] An angle adjustment structure for driving the material guiding air cavity 5 is installed at the bottom of the drone 1.

[0058] Further, as Figure 4 shown, a discharge port 401 is formed at the bottom of the material pushing box 4. The material pushing box 4 is rotatably connected with a material pushing plate 41. Inner grooves 4101 are formed in a circular pattern on the material pushing plate 41. The material pushing plate 41 is located in the inner cavity of the material pushing box 4, and one of the inner grooves 4101 communicates with the material guiding air cavity 5.

[0059] As Figure 5 shown, seed capsules 6 are placed in the inner cavity of the material pushing box 4.

[0060] During the rotation of the material pushing plate 41, the seed capsules 6 in the material pushing box 4 will fall into the inner grooves 4101, and are discharged from the discharge port 401 and fall into the material guiding air cavity 5 as the material pushing plate 41 rotates.

[0061] Further, in combination with Figure 4 and Figure 5 , the material guiding air cavity 5 includes a material guiding cavity 501 and a air supply cavity 502. One end of the material guiding cavity 501 communicates with the discharge port 401, and the other end communicates with the air supply cavity 502.

[0062] One end of the air supply cavity 502 is open, and the other end communicates with the air outlet of the fan 3.

[0063] As Figure 10 shown, a material guiding block 56 is fixedly installed in the air supply cavity 502. A material guiding surface 5601 is arranged on one side of the material guiding block 56. The material guiding surface 5601 and the air supply cavity 502 form a discharge port 57.

[0064] Further, as Figures 8 - 11 shown, a material guiding cavity baffle 51 is rotatably connected to the inner wall of the material guiding air cavity 5. The material guiding cavity baffle 51 is located at the junction of the material guiding cavity 501 and the air supply cavity 502. A first magnet 52 is embedded on one side of the bottom of the material guiding cavity 501. The first magnet 52 attracts the free end of the material guiding cavity baffle 51.

[0065] Further, as Figure 6 shown, the discharging structure includes a pressing T-plate 7. The pressing T-plate 7 is slidably connected to the material guiding air cavity 5 and its bottom extends into the material guiding cavity 501 and is located above the material guiding cavity baffle 51.

[0066] As Figure 9 shown, sliding rods 71 are symmetrically arranged at the horizontal end face of the pressing T-plate 7. Corresponding sliding grooves 503 are formed at the top of the material guiding air cavity 5. The bottom ends of the sliding rods 71 are slidably connected in the corresponding sliding grooves 503. Springs 72 are sleeved on the sliding rods 71. The two ends of the springs 72 respectively abut against the horizontal end face of the pressing T-plate 7 and the top of the material guiding air cavity 5.

[0067] As shown Figure 6 in the figure, pressing rods 73 are symmetrically arranged on both sides of the pressing T-plate 7.

[0068] Specifically, as the feeding disc 41 rotates, the seed capsule 6 is discharged from the inner groove 4101 and falls into the material guiding cavity 501, and moves along the track surface of the material guiding cavity 501 to the top of the material guiding cavity baffle 51, pressing down the pressing T-plate 7. During the descending process of the pressing T-plate 7, its end will squeeze the material guiding cavity baffle 51, and the material guiding cavity baffle 51 stops attracting the first magnet 52 and rotates counterclockwise. At this time, the material guiding cavity 501 and the air supply cavity 502 are in a communicating state, and the seed capsule 6 in the material guiding cavity 501 will fall into the air supply cavity 502 and roll along the discharge port 57;

[0069] Furthermore, as shown Figures 6 - 12 in the figure, the discharging structure further includes a first driving motor 74. The first driving motor 74 is installed on one side of the feeding box 4 by bolts. The output shaft of the first driving motor 74 is fixedly connected to the feeding disc 41 and extends out from the other side of the feeding box 4. Symmetrically fixed sleeves are provided on the output shaft of the first driving motor 74 with first driving gears 75, and the two first driving gears 75 are located on both sides of the feeding box 4;

[0070] Docking shafts 53 are symmetrically rotatably connected to both sides of the material guiding air cavity 5. A driven gear 76 is fixedly sleeved on the docking shaft 53 close to the first driving gear 75, and the first driving gear 75 and the driven gear 76 on the same side are meshed with each other;

[0071] Ratchet wheels 77 are fixedly sleeved on both docking shafts 53, and the ratchet teeth of the two ratchet wheels 77 are abutted against the corresponding pressing rods 73;

[0072] The first driving motor 74 is electrically connected to the drone 1.

[0073] Specifically, the first driving motor 74 drives the feeding disc 41 and the first driving gear 75 to rotate counterclockwise through the output shaft, thereby providing rotational power for the feeding disc 41. At the same time, under the meshing action, the two driven gears 76 are driven to rotate clockwise, and the driven gear 76 drives the corresponding ratchet wheel 77 to rotate clockwise. When the ratchet wheel 77 rotates, it will squeeze the corresponding pressing rod 73 through the ratchet teeth, thereby pressing down the pressing T-plate 7.

[0074] Furthermore, as shown Figure 6 and Figure 7 in the figure, the material guiding air cavity 5 is provided with a pressing rod limiting groove 504 corresponding to the pressing rod 73. The pressing rod 73 is slidably connected to the corresponding pressing rod limiting groove 504. The pressing rod 73 can be limited through the pressing rod limiting groove 504 to improve the stability of the pressing rod 73 during sliding;

[0075] When the pressure rod 73 moves downward, the slide rod 71 will slide downward along the corresponding chute 503. At the same time, the spring 72 sleeved on the slide rod 71 is compressed. During the counterclockwise rotation of the material guide chamber baffle 51, the air supply chamber 502 will be blocked, as Figure 6 , Figure 8 , Figure 10 and Figure 11 shown. An air release groove 505 is provided at the top of the air supply chamber 502. A rotatable air release baffle 54 is connected to the inner wall of the material guide air chamber 5. The air release baffle 54 is located at the junction of the air release groove 505 and the air supply chamber 502, as Figure 11 shown. A second magnet 55 is embedded on one side of the bottom of the air release groove 505. The second magnet 55 attracts the free end of the air release baffle 54 to prevent the air release baffle 54 from rotating under its own gravity; the air release baffle 54 is located between the material guide chamber baffle 51 and the fan 3;

[0076] As Figure 8 and Figure 12 shown, one side of the downward pressing T plate 7 is fixedly connected to a reverse L-shaped air release pressing plate 78. The vertical end of the air release pressing plate 78 penetrates through the material guide air chamber 5 and abuts against the top of the air release pressing plate 78.

[0077] When the pressure rod 73 moves downward, it will drive the air release pressing plate 78 to move downward together. When the air release pressing plate 78 moves downward, it will squeeze the air release baffle 54. At this time, the air release baffle 54 stops attracting the second magnet 55 and rotates counterclockwise. The air release groove 505 will be in communication with the air supply chamber 502, and the air in the air supply chamber 502 will be discharged from the air release groove 505.

[0078] When the seed capsule 6 in the material guide chamber 501 falls into the air supply chamber 502 and starts to roll along the opening end of the air supply chamber 502, at this time, the ratchet teeth of the ratchet wheel 77 stop contacting the pressure rod 73. The compressed spring 72 will quickly stretch and reset, pushing the downward pressing T plate 7 to move upward and reset. At this time, the squeezing force of the downward pressing T plate 7 on the material guide chamber baffle 51 and the air release pressing plate 78 on the air release baffle 54 disappears. At this time, under the action of the wind, the air release baffle 54 and the material guide chamber baffle 51 are blown, causing the air release baffle 54 and the material guide chamber baffle 51 to rotate clockwise and reset, waiting for the ratchet teeth of the ratchet wheel 77 to squeeze the pressure rod 73 next time. Among them, when the inner groove 4101 with the seed capsule 6 is in communication with the material guide chamber 501, at this time, the ratchet teeth of the ratchet wheel 77 just contact the corresponding pressure rod 73. The seed capsule 6 is discharged from the inner groove 4101 and falls into the material guide chamber 501. At the same time, the ratchet wheel 77 squeezes the corresponding pressure rod 73 through the ratchet teeth, causing the material guide chamber baffle 51 to open, so as to timely discharge the seed capsule 6 in the material guide chamber 501 into the air supply chamber 502;

[0079] After the air release baffle 54 and the material guiding chamber baffle 51 are reset, the air blown by the blower 3 at this time blows the rolling seed capsule 6, providing a thrust for the seed capsule 6 to move it along the material guiding surface 5601. During the movement, the seed capsule 6 can be adjusted from the horizontal state to perpendicular to the previous state through the arranged material guiding blocks 56, ensuring that after being ejected from the discharge port 57, the impact of air resistance on the seed capsule 6 is reduced. The seed capsule 6 is ejected from the discharge port 57 with a certain acceleration by the blower 3. After the seed capsule 6 contacts the soil, there is still a part of inertia in the seed capsule 6 that pierces into the soil, thereby fixing the seed capsule 6 and preventing the seed capsule 6 from rolling to other places due to the influence of wind after landing.

[0080] When the material guiding chamber baffle 51 and the air release baffle 54 are reset, the first magnet 52 is re-attracted to the material guiding chamber baffle 51, and the second magnet 55 is re-attracted to the air release baffle 54, preventing the material guiding chamber baffle 51 and the air release baffle 54 from automatically sagging and opening due to their own gravity.

[0081] Further, as Figure 2 and Figure 3 shown, the material feeding box 4 is fan-shaped, and arc-shaped sliding rails 402 are symmetrically arranged on both sides of the material feeding box 4. Sliding grooves 201 are symmetrically opened on the inner wall of the docking frame 2, and the sliding rails 402 are slidably connected to the sliding grooves 201 on the same side.

[0082] Further, the angle adjustment structure includes a second driving motor 8 and a toothed plate 81. The second driving motor 8 is fixedly connected to the bottom of the drone 1, and a second driving gear 82 is fixedly connected to the output shaft of the second driving motor 8. The toothed plate 81 is arc-shaped and its bottom is fixedly connected to the top of the material feeding box 4. The second driving gear 82 meshes with the toothed plate 81;

[0083] The axis of the toothed plate 81 is at the same position as the axis of the sliding rail 402;

[0084] The second driving motor 8 is electrically connected to the drone 1.

[0085] Specifically, when used on land with a certain slope, the second driving motor 8 drives the second driving gear 82 to rotate through the output shaft. Under the meshing action with the toothed plate 81, the material feeding box 4 will move in the sliding groove 201 through the sliding rail 402, thereby adjusting the angle of the discharge port 57. The preferred adjustment angle is that the discharge port 57 forms an angle of 30 - 70 degrees with the horizontal plane. Compared with vertically shooting the seed capsule 6 towards the slope, when the seed capsule 6 is shot towards the slope at a certain inclination angle, the contact area between the end of the seed capsule 6 and the slope will be larger, so that the seed capsule 6 can more easily pierce into the sandy soil on the slope, effectively preventing side slip.

[0086] Embodiment 2

[0087] AsFigures 1 - 12 As shown in the figure, the following improvements are made to this embodiment based on Embodiment 1: Further, as Figure 1 shown, a storage battery 9 is electrically connected to the top of the drone 1 to supply power to the drone 1, the first driving motor 74, and the second driving motor 8;

[0088] A wind resistance detector 10 is electrically connected to one side of the drone 1. The wind resistance detector 10 detects the wind speed and feeds back to the drone 1 in a timely manner. When the wind resistance received is greater, the flight height of the drone 1 will be correspondingly reduced, thereby shortening the distance between the discharge port 57 and the ground, shortening the travel of the seed capsule 6, and reducing the influence of the wind resistance on the seed capsule 6.

[0089] In summary, the working process of the present utility model is as follows:

[0090] The first driving motor 74 drives the feeding disk 41 and the first driving gear 75 to rotate counterclockwise through the output shaft, thereby providing rotational power for the feeding disk 41. During the rotation of the feeding disk 41, the seed capsules 6 in the feeding box 4 will fall into the inner groove 4101 and be discharged from the discharge port 401 and fall into the guiding air cavity 5 as the feeding disk 41 rotates;

[0091] At the same time, the first driving gear 75 drives the two driven gears 76 to rotate clockwise under the meshing action. The driven gears 76 drive the corresponding ratchets 77 to rotate clockwise. When the ratchets 77 rotate, they will squeeze the corresponding pressure rods 73 through the ratchet teeth, thereby pressing down the lower pressing T-plate 7. During the downward movement of the lower pressing T-plate 7, its end will squeeze the guiding cavity baffle 51. The guiding cavity baffle 51 stops attracting the first magnet 52 and rotates counterclockwise. At this time, the guiding cavity 501 and the air supply cavity 502 are in a communicating state. The seed capsules 6 in the guiding cavity 501 will fall into the air supply cavity 502 and roll along the discharge port 57;

[0092] When the air release baffle 54 and the guiding cavity baffle 51 are reset, the wind blown by the blower 3 at this time blows the rolling seed capsules 6, providing a thrust for the seed capsules 6 to move them along the guiding surface 5601. During the movement, the seed capsules 6 can be adjusted from the horizontal state to a state perpendicular to the previous state through the arranged guiding blocks 56, ensuring that after being ejected from the discharge port 57, the impact of the wind resistance on the seed capsules 6 is reduced. The blower 3 makes the seed capsules 6 be ejected from the discharge port 57 with a certain acceleration. After the seed capsules 6 contact the soil, there is still a part of inertia in the seed capsules 6 and they will plunge into the soil, thereby fixing the seed capsules 6 and preventing the seed capsules 6 from rolling to other places due to the influence of the wind after landing;

[0093] When it is necessary to adjust the angle of the discharge port 57, the second drive motor 8 drives the second driving gear 82 to rotate through the output shaft. Under the meshing action with the toothed plate 81, the feeding box 4 will move in the sliding groove 201 through the slide rail 402, so as to adjust the angle of the discharge port 57.

[0094] However, as is well known to those skilled in the art, the working principles and wiring methods of the drone 1, the first drive motor 74, the second drive motor 8, the storage battery 9 and the wind resistance detector 10 are common knowledge. They all belong to conventional means or well-known common sense, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0095] The above different embodiments can be combined, replaced and used in combination with each other.
