Rotary wing type unmanned aerial vehicle for spraying pesticides

Abstract

The invention discloses a rotary wing type unmanned aerial vehicle for spraying pesticides. The rotary wing type unmanned aerial vehicle comprises a main body and a spraying rack body arranged at the bottom of the main body, wherein a pesticide storage cavity is formed in the spraying rack body; stirring blades are arranged on the inner bottom wall of the pesticide storage cavity; the bottoms of the stirring blades are in fit connection with a motor which is embedded in the inner bottom wall of the pesticide storage cavity and is fixedly connected with the inner bottom wall of the pesticide storage cavity; a transmission cavity is formed in the position, below the pesticide storage cavity, in the spraying rack body; guide grooves are symmetrically formed in the left and right sides of the inner bottom wall of the transmission cavity; guide blocks are arranged in the guide grooves; a first supporting plate and a second supporting plate which are symmetrically arranged up and down are arranged in the middle in the transmission cavity; the first supporting plate and the second supporting plate extend to the front and back sides; a rotating shaft which extends up and down is arranged in the middle position between the first supporting plate and the second supporting plate; and an extension section of the top of the rotating shaft penetrates through the end face of the top of the first supporting plate and is in rotational fit connection with the end face of the top of the first supporting plate. According to the rotary wing type unmanned aerial vehicle, the structure is simple, automatic disassembly and assembly can be achieved, later maintenance and carrying are facilitated, the service life is prolonged, the pesticide spraying covering area is increased, and pesticide concentration is uniform.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rotary-wing 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 advant...

AI Technical Summary

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.
