[0002] Unmanned aerial vehicles, or "drones" for short, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Drones can be divided into military and civilian applications according to their fields of application. In the military, drones are divided into reconnaissance aircraft and target aircraft. Drones are currently also used in aerial photography, agricultural plant protection, surveying and mapping, and other fields, greatly expanding the use of drones themselves. Drones used in the agricultural field can be used to sow seeds or spray pesticides, but traditional drones directly pour materials when sowing seeds. When pouring materials, they cannot automatically adjust the sowing range according to the width of the ridges, which will cause a certain degree of waste of seeds.

[0027] The disclosed embodiments are intended to solve the problem that traditional drones directly pour materials when sowing seeds, and cannot automatically adjust the sowing range according to the width of the ridges when pouring materials, which will cause a certain degree of seed waste. In view of this, the disclosed embodiments propose an airborne sowing device for agricultural drones, which can control the flow rate of seeds by setting a sowing mechanism, and can control the flow rate of seeds by adjusting the gap between the guide plate and the closed baffle. At the same time, a guide baffle is set under the guide plate to achieve the range of seed sowing. By controlling the flow rate of seeds and the sowing range, automatic adjustment can be achieved for ridges of different widths, thereby avoiding seed waste.

[0028] like Figures 1 to 5 As shown, an airborne sowing device of an agricultural UAV includes a control unit 1, a material box 2, a sealing cover 3 and a sowing mechanism 4. The control unit 1 is installed at the bottom of the UAV, a material box 2 is installed on one side of the control unit 1, a sealing cover 3 is installed on the upper end of the material box 2, and a sowing mechanism 4 is installed at the bottom of the material box 2. The sowing mechanism 4 is used to automatically adjust the sowing range according to the width of the ridge, and automatically clear the sowing mechanism 4 when it is blocked.

[0029] like Figures 1 to 5 As shown, the sowing mechanism 4 includes a rotating motor 41, a rotating shaft 42, a rotating disk 43, a stirring piece 44, a closed baffle 45, a guide disk 46 and a guide baffle 47. The rotating motor 41 is installed at the bottom of the drone, and the rotating motor 41 is used to provide power to the entire sowing mechanism 4; the output shaft of the rotating motor 41 passes through the sealing cover 3, and the output shaft of the rotating motor 41 is connected to one end of the rotating shaft 42, and the rotating shaft 42 is coaxially installed with a rotating disk 43 and a guide disk 46, and the rotating shaft 42 can be extended and retracted up and down, and the rotating shaft 42 is used to drive the rotating disk 43 and the guide disk 46 to rotate; the rotating disk 43 is arrayed with stirring pieces 44, and the stirring pieces 44 are used to scatter the seeds in the material box 2; the closed baffles 45 are symmetrically installed at the bottom of the material box 2, and the closed baffles 45 are used to adjust the descending speed of the seeds; the guide disk 46 is surrounded by guide baffles 47; the guide baffles 47 are used to guide the seeds;

[0030] During operation, the staff controls the drone to take off, and the rotating motor 41 rotates at this time, and the closed baffle 45 closes the entire material box 2. When the drone flies to the specified position, the distance of the field ridge is measured by its smart chip, and then the control unit 1 controls the closed baffle 45 to open a certain amplitude, and at the same time adjusts the distance between the guide plate 46 and the closed baffle 45 by adjusting the rotating shaft 42 to control the efficiency of the discharge, and at the same time, the control unit 1 adjusts the inclination angle of the guide baffle 47 to complete the sowing work;

[0031] By adopting the above-mentioned sowing mechanism 4, the flow rate of seeds can be controlled by adjusting the gap between the guide plate 46 and the closed baffle 45. At the same time, a guide baffle 47 is set under the guide plate 46 to achieve the range of seed sowing. By controlling the flow rate of seeds and the sowing range, automatic adjustment can be achieved for ridges of different widths, thereby avoiding seed waste.

[0032] like Figures 2 to 3 As shown, the stirring blades 44 are made of soft plastic material. The stirring blades 44 are set to be made of soft plastic material to avoid damage to the seeds by the stirring blades 44, and also to better disperse the seeds in the material box 2; and the stirring blades 44 are arranged in three groups in the longitudinal array. The stirring blades 44 are arranged in three groups to prevent some seeds from not being hit by the stirring blades 44, thereby causing seed agglomeration.

[0033] like Figures 2 to 3 As shown, the diameter of the stirring blade 44 decreases from top to bottom. The diameter of the stirring blade 44 is set to gradually decrease in order to match the gradually decreasing diameter of the material box 2, thereby avoiding the situation that some seeds cannot be hit by the stirring blade 44.

[0034] like Figure 5 As shown, the closed baffle 45 is composed of two pieces and one end of the closed baffle 45 is provided with a semicircular groove 451 which is consistent with the diameter of the rotating shaft 42; the seeds at the bottom of the material box 2 can be sealed by the two closed baffles 45, and the semicircular groove 451 is provided to prevent the closed baffle 45 from interfering with the rotation of the rotating shaft 42.

[0035] like Figure 4 As shown, the combination of the two closed baffles 45 is in an inverted cone shape; the guide plate 46 is in a cone shape, and the guide plate 46 is provided with a flow dividing thread 461 in an array. The closed baffle 45 is set in an inverted cone shape to cooperate with the guide plate 46 in a positive cone shape, thereby achieving control of the sowing efficiency.

[0036] like Figure 2 As shown, there are four guide baffles 47, and the guide baffles 47 are trapezoidal. The sowing angle is changed by changing the inclination angle of the guide baffles 47, thereby avoiding the inability to automatically adjust the sowing range according to the width of the ridge when pouring the material, which will cause a certain degree of seed waste.

[0037] The working principle of the utility model is as follows: the staff controls the UAV to take off, at which time the rotating motor 41 rotates, and the closing baffle 45 closes the entire material box 2. When the UAV flies to the specified position, the distance of the field ridge is measured by its intelligent chip, and then the control unit 1 controls the closing baffle 45 to open a certain amplitude, and at the same time adjusts the distance between the guide plate 46 and the closing baffle 45 by adjusting the rotating shaft 42 to control the discharge efficiency. At the same time, the control unit 1 adjusts the inclination angle of the guide baffle 47 to complete the sowing work.

[0038] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
