Self-propelled spraying machine with automatic targeting in orchard and spraying method thereof

Abstract

The invention discloses a self-propelled spraying machine with automatic targeting in an orchard and a spraying method thereof. According to the self-propelled spraying machine, the automatic targeting is realized, the influence by the environment is less, the response time is fast, no leaked spraying or more spraying is caused and the waste of pesticide is prevented. The spraying machine comprises a rack, a traveling device, a spraying device with a plurality of spraying nozzles, laser detecting devices and a central processor; the laser detecting devices correspond to the spraying heads in a one-by-one manner; each laser detecting device comprises a laser generator, a laser receiver, a signal processor and a controller; the spraying heads and the laser detecting devices are distributed on the rack at the same corresponding angle; the central processor is connected with all spraying-nozzle control devices. The spraying method disclosed by the invention comprises the steps that the laser generator generates laser transmitting signals, the laser receiver receives reflecting signals, and if the target distance is in the set distance range, the target is the current target; if the former signal does not detect the current target, the latter reflecting signal detects the current target, and then the spraying is carried out; if the three continuous reflecting signals do not detect the target, the spraying is stopped; the other states are maintained to be the original states.

Description

technical field [0001] The technology relates to an orchard sprayer, specifically, a self-propelled orchard automatic target sprayer and a spraying method thereof. Background technique [0002] Existing orchard sprayers generally include a frame, a traveling device, and a spraying device, which require manual control during spraying and cannot realize automatic operation. Even if there is an orchard sprayer that can be operated automatically, it cannot distinguish whether there is a target or not when spraying, and it always sprays continuously. The interval spray between trees is an ineffective spray, which cannot be effectively deposited on the leaves of fruit trees, and the waste of medicinal liquid is large. Air-driven spraying technology is a widely used and very effective orchard spraying technology. This technology can significantly improve the penetration and deposition rate of droplets. By controlling whether to spray according to the interval between fruit trees a...

Problems solved by technology

[0006] The detection technology based on image processing can obtain a large amount of information through the camera, and can accurately judge the type and size of the tree according to the database, but the capital investment is large, the information processing is slow, and the response time is long.
