Background

In the modern agricultural production management process, most links realize mechanized operation, but the prevention and control of crop diseases and insect pests are not realized, so that the problems of unprofessional prevention and control, disordered application, large pesticide residue, serious environmental pollution and the like exist.

In order to improve the spraying efficiency of pesticide to crops, an unmanned aerial vehicle is adopted to spray a farmland, when the unmanned aerial vehicle in the prior art is applied to agriculture, most unmanned aerial vehicles can only fly above the crops to perform mechanical spraying operation, and cannot spray according to the actual requirement, namely the wind speed, if the wind speed is too high, the flying height cannot be adjusted in time, the sprayed pesticide can be blown away by strong wind, the spraying effect cannot reach the expectation, in addition, as the unmanned aerial vehicle carries a large amount of liquid medicine, when the unmanned aerial vehicle flies, slight shaking can cause the vibration of the liquid medicine; the in-process that sprays again, for making the nozzle be close to crops, and lead to fuselage inclination too big, in addition very fast flight speed, the liquid medicine acutely vibrates and must influence unmanned aerial vehicle's flight situation, consequently an agricultural unmanned aerial vehicle adjustable equipment based on Bernoulli's principle takes place at the right moment

Disclosure of Invention

In order to achieve the purposes of enabling the liquid medicine to be not influenced by wind power and reducing the vibration degree of the liquid medicine by being close to the surface of crops, the invention provides the following technical scheme: the utility model provides a reduce agricultural unmanned aerial vehicle that sprays of sectional type that liquid medicine rocked, includes the organism, the fixed surface of organism is connected with the liquid reserve tank, and the both sides swing joint of liquid reserve tank has prevents shaking the mechanism, prevents shaking one side that the mechanism kept away from the liquid reserve tank and rotates and be connected with the wing, and the upper portion swing joint of wing has the screw, the lower part fixedly connected with nozzle of wing, prevent shaking the mechanism and include the pivot, the surface of pivot has the rotor through delivery stem swing joint, and the inside roll connection of rotor has the rolling element, and the inside of rotor just is located the fixed surface of rolling element and is connected with the infusion passageway, and one side fixedly connected.

The invention has the beneficial effects that:

1. the propeller is driven to rotate to drive the body to fly in the air, the propeller rotates to form an air flow layer on the surface of the propeller, and the Bernoulli principle is utilized: the flow rate at the top is high, the pressure is small, the flow rate at the bottom is low, and the pressure is high; the pressure difference that causes like this has produced the uplift power, consequently can be with the liquid medicine in the liquid reserve tank from the liquid flow pipe suction in the wing, and carry to in preventing shaking the mechanism, when meetting strong wind weather, change the rotational speed of organism both sides screw, make both produce different uplift power, the one side that the uplift power is big drives the rolling element in the rotor and carries out clockwise rotation on rotating the cover surface, make the wing kickup, otherwise the one side wing that the uplift power is little is crooked downwards, the wing that the kickdown made the nozzle be close to the crops surface, thereby reached and pressed close to the crops surface and made the liquid medicine not influenced by the wind-force effect.

2. The wings on the two sides are at different heights due to different uplifting forces, and the liquid storage tank is not changed along with the movement of the wings due to the fixed connection of the rotating cover and the liquid storage tank in the anti-shaking mechanism, and in addition, the liquid medicine in the liquid storage tank flows into the liquid conveying channel in the wings at the lower part under the action of gravity, so that the effect of reducing the vibration degree of the liquid medicine is achieved.

Preferably, teeth are fixedly connected to the inner portion of the rotating body and located on two sides of the infusion channel.

Preferably, the inside of the wing is fixedly connected with a liquid flow pipe.

Preferably, a gear channel is fixedly connected to the inside of the liquid storage tank.

Preferably, the interior of the gear channel is movably connected with the rotating shaft.

Preferably, the liquid pesticide is contained in the liquid storage tank.

Preferably, the liquid collecting groove is in a conical design, and one side far away from the liquid storage tank is provided with a wide opening.

Preferably, the surface of the rotating body is movably connected with a rotating cover, and the rotating cover is fixedly connected with the liquid storage tank.
