Holder adopts the top that is formed by connecting by 4 blocks of vertical side plates and bottom to be the square box structure of opening, and the open top of holder is docked with the bottom opening of seed-box;
By quantitatively sowing roller, roller blade and common cooperation of holder realizing quantitative seeding;
The seed of discharge dispelled realize loose kind of wind-force by wind-force kind of the device that falls apart, thus be conducive to sowing evenly;
The process that seeding and wind-force fall apart kind is as follows:
During quantitative sowing roller non rotating, quantitatively sowing roller and roller blade seal the passage between holder open top and bottom opening jointly, prevent seed from falling from holder bottom opening, and now seeding apparatus is in and suspends sowing state;
When quantitative sowing roller rotates, seed first drains to adjacent roller blade from the outlet of seed-box and quantitatively sow between roller the common kinds of bank deposits cavity formed, along with the rotation of roller blade, when this kinds of bank deposits cavity moves to the below of holder, the seed stored in kinds of bank deposits cavity is released, and wind-force fall apart kind of device wind-force effect under disperse and fall, now seeding apparatus is in seeding operation state;
The bottom of aircraft is provided with 2 parallel stationary pipes (3); Be provided with 2 suspension members (23) in the both sides of holder, described suspension member is provided with the half slot with described stationary pipes adaptation, and 2 suspension members buckle respectively in 2 stationary pipes;
Described aircraft is provided with wireless receiver, and wireless receiver receives remote signal and controls the flight attitude of aircraft and control the action of quantitatively sowing roller and fan.
Seeding apparatus is multiple, and multiple seeding apparatus is unified to be controlled, or each seeding apparatus controls separately;
The outer place of roller blade is provided with sheet rubber;
Described aircraft is single rotor craft, adopts battery or fuel oil to drive;
Described aircraft comprises fuselage (5) and the power take-off mechanism be connected with fuselage, gearbox (8), main rotor (9), tail rotor (10) and foot rest (12);
Power take-off mechanism is connected with gearbox transmission by main synchronous belt drive mechanism (7); Gearbox drives main rotor to rotate; Gearbox is also in transmission connection by tail step tape handler and tail rotor; Foot rest is arranged on the bottom of fuselage.
