Embodiment 1

[0046] see figure 1 , the airborne device suitable for unmanned aerial vehicle sowing operations in this embodiment includes a spreading device 2 arranged under the unmanned aerial vehicle 1 .

[0047] see figure 1 and figure 2 , the spreading device 2 includes a material box 21, a material stirring mechanism 22, a discharge adjustment mechanism 24, a material spreading mechanism 23 and a load plate 25, wherein the material stirring mechanism 22 is arranged in the material box 21, and the material spreading The mechanism 23 is arranged under the material box 21 , and the load plate 25 is arranged at the upper end of the material box 21 .

[0048] Figure 1 ~ Figure 3 , the material box 21 is composed of a box wall 211 with a circular cross section and a bottom plate 212, wherein the bottom plate 212 is provided with a leak 213 for dropping materials such as seeds or fertilizers. The material box 21 has a rigid body structure and is made of plastic light materials to reduc...

Embodiment 2

[0064] Referring to 4, the difference between this embodiment and Embodiment 1 is that in this embodiment, the material stirring mechanism 22 adopts a blade mechanism, and the blade mechanism includes a motor and a blade connected to the motor. Wherein, the motor is fixed on the load plate 25 through the connecting rod 243 ; the blade is arranged coaxially with the material box 21 , and its turning direction is opposite to that of the wheel disc 231 in the material spreading mechanism 23 . The material particles are directly agitated by the blades, so that the material particles are kept uniformly distributed in the material box 21 , thereby ensuring that the materials around the leak 213 can fall evenly.

Embodiment 3

[0066] The difference between this embodiment and Embodiment 1 is that in this embodiment, on the basis of one ducted fan mechanism in Embodiment 1, the material stirring mechanism is also provided with two other ducted fan mechanisms. The axial direction of the ducted fan of the first ducted fan mechanism is perpendicular to the axial direction of the ducted fan of the first ducted fan mechanism, and the rotation direction of the ducted fan in the two ducted fan mechanisms is opposite. This allows the material to be fully stirred in the material box, so that the intertwined material particles (such as sprouted seeds) are fully separated so that they can evenly fall from the leak.

Abstract

The invention discloses an onboard device suitable for the sowing job of an unmanned aerial vehicle and a sowing method. The onboard device comprises a scattering device arranged below the unmanned aerial vehicle, wherein the scattering device comprises a material box, a material stirring mechanism, a material discharging adjusting mechanism and a material scattering mechanism; the material stirring mechanism is arranged inside the material box; the material scattering mechanism is arranged below the material box; the material box comprises a box wall and a baseboard; a ventage is formed in the baseboard; the material discharging adjusting mechanism comprises a switch baffle arranged in the ventage and an actuating mechanism used for pushing the switch baffle to move in the ventage and adjusting the size of the leak; the material scattering mechanism comprises a side plate connected to the bottom of the material box, a wheel disc motor and a wheel disc connected with the wheel disc motor; the wheel disc is arranged on the inner side of the side plate; a scattering openings are formed in the side plate. According to the invention, the onboard device has the advantages of being small in size, low in cost, high in flexibility and convenient for controlling.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to an airborne device and a sowing method suitable for unmanned aerial vehicle sowing operations. Background technique [0002] Sowing is a quick and easy method of direct seeding for sowing small-sized seeds, and it is also a relatively extensive method of direct seeding, which requires a large amount of seeds and is difficult to control the density. With the rise of agricultural mechanization operations, the sowing method has begun to be favored by the majority of users due to its high operating efficiency. The current sowing operation methods include manpower and mechanical sowing. Manpower sowing not only has high labor intensity and low efficiency, but also has obvious uneven sowing density, which reduces the output of seed production and takes a lot of time; mechanical sowing replaces manpower. Spreading can effectively improve work efficiency. But the exi...
