Plant protection unmanned aerial vehicle capable of keeping curve uniform spraying and control method thereof

Abstract

The invention belongs to the field of unmanned aerial vehicles, and in particular relates to a plant protection unmanned aerial vehicle capable of keeping curve uniform spraying. The unmanned aerial vehicle comprises a rack, and a pesticide box is arranged in the rack; two liquid discharging pipes are arranged on the two sides of the bottom of the pesticide box; an arc-shaped groove is formed in the upper side of the pesticide box; three magnetic sliding blocks are arranged in the arc-shaped groove; partition plates are arranged among the three magnetic sliding blocks; the sides, away from themiddle magnetic sliding block, of the magnetic sliding blocks on the left side and the right side are fixedly connected with steel wire ropes; rope grooves are formed in the two sides of the pesticide box; the steel wire ropes are arranged in the rope grooves, the outer side of each steel wire rope is sleeved with a first spring, the two ends of each first spring are fixedly connected with the magnetic sliding blocks and the side wall of the arc-shaped groove correspondingly, a fixing block is arranged in the middle of the liquid discharging pipes, a sliding groove is formed in the fixing block, and a staggered sliding plate is arranged in the sliding groove. When the unmanned aerial vehicle makes a turn, the spraying amount of pesticide on the inner side of the turn can be reduced, and crops are prevented from being damaged due to excessive pesticide receiving.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and in particular relates to a plant protection unmanned aerial vehicle capable of maintaining uniform spraying on curves and a control method thereof. Background technique [0002] Traditional agricultural crop spraying methods have backward spraying equipment, serious waste and loss of pesticides, poor control effect, repeated use of pesticides, resulting in serious pesticide residues, direct contact between pesticide applicators and pesticides, frequent occurrence of productive poisoning, and continuous increase in labor costs, etc. series of questions. [0003] In recent years, drones have been favored by farmers due to their simple structure, easy maintenance, low maintenance cost, small size, and light weight, and have gradually entered agricultural production. The existing plant protection UAV spraying method relies entirely on the manual operation of the UAV driver, and the driver...

AI Technical Summary

Problems solved by technology

The existing plant protection UAV spraying method relies entirely on the manual operation of the UAV driver, and the driver decides the location and flow of chemical spraying. However, when the UAV turns, the rotation angle is the same, but the distance from the outside to the rotation point It is greater than the distance from the inner side to the rotation point, which causes the outer nozzle to pass a longer distance, so that, at the same time, the spraying density of the inner and outer sides of the UAV is different, causing the seedlings to die, especially in the land with a large curvature. When the drone is spraying, the drone needs more time when turning, so that the spraying agent is more, which can easily cause the death of the seedlings
