Unmanned aerial vehicle for pesticide spraying

Abstract

The invention discloses an unmanned aerial vehicle for pesticide spraying. The unmanned aerial vehicle includes a main body, and a spraying frame arranged on the bottom of the main body; a pesticide storage chamber is arranged in the spraying frame; a stirring impeller is arranged on an inner bottom wall of the pesticide storage chamber; the bottom of the stirring impeller is in matching connection with a motor which is embedded in and is fixedly connected to the inner bottom wall of the pesticide storage chamber; a transmission chamber is arranged in the spraying frame under the pesticide storage chamber; guide grooves are symmetrically formed in the left side and the right side of an inner bottom wall of the transmission chamber; a guide block is arranged in each guide groove; a first supporting plate and a second supporting plate which are vertically symmetrical to each other are arranged on the internal center of the transmission chamber, and the first supporting plate and the second supporting plate extend forward and backward; a rotation shaft extending vertically is arranged on the center between the first supporting plate and the second supporting plate; and a top extensionsection of the rotation shaft passes through a top end surface of the first supporting plate and is rotatably connected. The unmanned aerial vehicle is simple in structure, can achieve automatic demounting, can facilitate later maintenance and carrying, can prolong the service life, can enlarge the coverage area of pesticide spraying, and can allow the even concentration of the pesticide.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an unmanned aerial vehicle for spraying pesticides. Background technique [0002] At present, most agricultural pesticides in my country are sprayed by manpower or agricultural machinery. The efficiency of the operation is low. People were poisoned or even died. With the rapid development of science and technology, the use of drones has become more and more extensive, and the infrastructure related to agriculture is also constantly improving. Spraying drones use intelligently controlled spraying drones to replace artificial traditional Spraying pesticides with spraying equipment greatly reduces the demand for labor in agricultural production, while UAVs have low operating height, less drift, can hover in the air, do not need special take-off and landing airports, and the downward airflow generated by the rotor helps to increase The fog flow has many advantages such a...

Problems solved by technology

[0002] At present, most agricultural pesticides in China are sprayed by manpower or agricultural machinery, and the operation efficiency is low. The sprayed liquid can only cover the surface of the crops, and there is still the possibility of being harmed by pests. Moreover, the use of manpower to spray pesticides directly endangers the personal health of workers and is easy to cause People were poisoned or even died. With the rapid development of science and technology, the use of drones has become more and more extensive, and the infrastructure related to agriculture is also constantly improving. Spraying drones use intelligently controlled spraying drones to replace artificial traditional Spraying pesticides with spraying equipment greatly reduces the demand for labor in agricultural production, while UAVs have low operating height, less drift, can hover in the air, do not need special take-off and landing airports, and the downward airflow generated by the rotor helps to increase The fog flow has many advantages such as penetrability to crops and high control effect. The medicine box of the existing pesticide spraying drone is set inside the drone, and the liquid in the medicine box will also cause corrosion and damage to the internal structure of the drone. The lifespan of the UAV is greatly reduced. In addition, the area covered by the existing spraying device for spraying pesticides is limited, and the efficiency of spraying pesticides has great limitations.

In addition, pesticide precipitation certainly has its own rules, and precipitation leads to uneven concentration of pesticides after spraying from the nozzle.
