Unmanned aerial vehicle for plant protection

Abstract

The invention relates to an unmanned aerial vehicle for plant protection. The unmanned aerial vehicle for plant protection comprises a center disk, a maintenance end cover and a medicine box, wherein the maintenance end cover and the medicine box are arranged on the center disk; a plurality of mounting holes for being matched with vehicle arms are formed in the center disk; motors and rotors which are connected with rotating shafts of the motors and arranged on the upper portions of the vehicle arms are arranged at the ends of the vehicle arms; a control device is arranged in the center disk and is in signal connection with the motors; the positions, on the lower portions of the rotors, of the bottoms of the vehicle arms are detachably connected with hanging rods connected with nozzles through sleeves; the nozzles communicate with the bottom of the medicine box through a medicine pipe equipped with a medicine pump; buffer gaskets are integrally arranged at the bottom of the medicine box; a limiting nail is fixedly arranged in the position, where the inner walls of the buffer gaskets make contact with the medicine box, of the bottom of the medicine box; the limiting nail is sleeved with a damping spring, and the sharp portion of the limiting nail is arranged downward; and one end of the damping spring is fixedly connected with the medicine box, and the other end of the damping spring is located on the upper portion of the sharp portion of the limiting nail. According to the unmanned aerial vehicle for plant protection, the structure is simple, the design is ingenious, vibration impact in the falling process of the unmanned aerial vehicle can be effectively buffered, and damage to the unmanned aerial vehicle structure is prevented.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for plant protection. Background technique [0002] The plant protection UAV can spread pesticides and fertilizers in the air. It has high flexibility and is not affected by the ground terrain. It is especially suitable for mountainous areas with low ground flatness. [0003] Compared with traditional agricultural plant protection machinery, UAVs have obvious advantages: 1) UAVs fly in the air without leaving tracks or damaging crops; 2) UAVs can hover in the air, take off and land vertically, and require The take-off and landing space is small, and it can take off and land in the field, and the take-off and landing are flexible; 3) The sprayers operate the pesticide by remote control, away from the spraying environment, and avoid the health hazards caused by close contact with pesticides; 4) With a GPS navigation system, it can Automatically pl...

AI Technical Summary

Problems solved by technology

When the body lands on the ground, the medicine box is in contact with the ground. On the one hand, the vibration will easily damage the body; machine life

Moreover, the existing plant protection UAV housing has poor sealing due to the connection problem between parts and parts, and cannot achieve dustproof and waterproof effects. Man-machine maintenance, especially cleaning, causes great disturbance
