Background technique

UAV abbreviation unmanned plane is not required to the mankind and supports the excellent spy such as device since unmanned plane has small in size Property, it can work under various adverse circumstances.Unmanned air vehicle technique was rapidly developed in recent years, and unmanned plane is according to its knot Structure feature can be there are many type, including fixed-wing unmanned plane, multi-rotor unmanned aerial vehicle, pilotless helicopter etc., wherein solid Determine that the wing is big with its aircraft figure, drugloading rate is big, cruise time length is with the obvious advantage, but also because it needs take-off venue, flight line It is more single, maintenance cost is higher, be not suitable for country plant protection drone market.

Structure is complicated that design maintenance cost is high for pilotless helicopter, and load capacity is limited, and accident rate is also higher, institute's duty Between be it is elongated, be not easy to fortune field, and multi-rotor unmanned aerial vehicle is in recent years because its structure is simple, operation is easy to operate, and at low cost It is honest and clean, favored by many manufacturers.But existing multi-rotor unmanned aerial vehicle downstream field is weak, and can not overturn blade makes medical fluid soak blade back Portion, plant protection effect is undesirable, occurs being easy folding paddle when accident, and fuselage fragility is easily damaged, and is delayed the duration fastly though repairing, is increased Add maintenance cost.

Utility model content

The purpose of the utility model is to provide a kind of power by force, drift is small, structure is simple, high reliablity more rotor plant protection Unmanned plane, to solve the above-mentioned problems of the prior art.

To realize above-mentioned target, the utility model provides following scheme:

A kind of more rotor plant protection drones, including fuselage, horn, undercarriage, rotor, rotor bracket, it is characterised in that also Including sprinkling system, control device and duct；Wherein,

The sprinkling system includes explosive box, peristaltic pump, centrifugal atomizing nozzle, grug transportation tube, and the explosive box is arranged in institute It states on undercarriage, the peristaltic pump is arranged in the drug storage upper box part；

The control device is mounted on the fuselage interior, including middle control module, IMU flight attitude sensor, PMU power supply Control module, GPS module, electron speed regulator；

The rotor has 4 to be mounted on the horn by the rotor bracket respectively, and the centrifugal atomizing nozzle is set It sets on the rotor bracket, is connected by the grug transportation tube with the peristaltic pump；

The duct has 4 to be separately positioned at the rotor, surrounds the rotor and is connected with the rotor bracket.

Preferably, the explosive box is internally provided with anti-surge plate.

Further, the fuselage bottom is provided with section board and drive module, the peristaltic pump and respectively with it is described Drive module is connected with the section board.

Preferably, the undercarriage is two-part structure, and upper portion is connected with the lower section by trapezoid boss structure It connects, the upper portion side is provided with mounting groove, and buffering baffle is equipped in the mounting groove.

Preferably, the guide groove to match with the rotor is provided within one week inside the duct.

For more rotor plant protection drones of the utility model using being driven by pure electric power, duct has reduction effect to blade tip flow-disturbing, Lift is increased dramatically, and load becomes larger.Duct covers entire rotor, and 4 ducts are circumferentially in cross distribution, aircraft weight in fuselage The heart more tends to balance, and is not susceptible to accident, if aircraft is out of control in the sky, air crash situation occurs for aircraft, will not damage machine The components such as the important part of body valuableness control, rotor and swirl atomizer like flying.Downstream field at culvert type structure air outlet is stronger, During sprinkling, downstream field energy, which adds, overturns crop leaf, makes medical fluid infiltration crop lower part and back, the stability of unmanned plane It is all strengthened with spraying efficiency.
