Unmanned aerial vehicle used for fruit tree spraying

Abstract

The invention discloses an unmanned aerial vehicle used for fruit tree spraying. The unmanned aerial vehicle used for fruit tree spraying comprises a unmanned aerial vehicle, a camera, a canopy relative height sensor, a front green sensor, a lower green sensor, a wind speed sensor and a spraying device. The spraying device comprises a servo motor, a pressure nozzle, a medicine chest, a supporting rod and a medicine delivery pipe. The method is characterized in that an unmanned aerial vehicle for surveying and mapping carries out surveying and mapping on a orchard so that an area where fruit trees are located is calculated; through a ground controller, a plant-protected unmanned aerial vehicle is controlled to dot each fruit tree; the camera shoots canopy images so as to calculate a canopy area and a circle center position; after flying to the circle center position, the plant-protected unmanned aerial vehicle is dropped to a position which has a h distance with a canopy; and a control module sends an instruction and the plant-protected unmanned aerial vehicle starts to spray. In the invention, according to a density of the crown canopy, variable insecticide spraying is realized, a pesticide application is accurate, efficiency is high and wastes of pesticide application are avoided.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to an unmanned aerial vehicle for spraying fruit trees. Background technique [0002] In our daily life, fruits are not uncommon, but in the production of fruit trees, pests and diseases often cause serious harm to the production of fruit trees, which reduces the yield and quality of fruit trees, causing great troubles to fruit farmers. With the development of science and technology, drone spraying has become a new method of pest control. Compared with traditional manual spraying, it has its unique advantages and plays a huge role in the field of agricultural plant protection, but there are also problems. , such as: poor spraying accuracy, especially for crops with large spacing, which often causes waste, and the spraying is not uniform enough, and the effect is not very good. Contents of the invention [0003] In view of the deficiencies in the above tech...
