Terrace orchard air-assisted variable toward-target sprayer and toward-target spraying method

Abstract

The invention provides a terrace orchard air-assisted variable toward-target sprayer and a toward-target spraying method, and belongs to the technical field of agriculture and forestry machinery. Thetoward-target sprayer comprises an upper air-assisted sprayer body and a lower air-assisted sprayer body which are installed at different heights, and when the terrace orchard air-assisted variable toward-target sprayer works, an industrial personal computer obtains the spraying delay time, the plant height and the crown volume according to point cloud data collected by a laser radar; a control chip adjusts the fog drop air supply distance, the spraying height and the spraying vertical direction angle accordingly; and the industrial personal computer further carries out fusion processing on information obtained by a GPS integrated navigation device and the point cloud data collected by the laser radar, the control chip controls a crawler-type chassis according to a processing result, and an advancing path is planned. According to the terrace orchard air-assisted variable toward-target sprayer, the pesticide applying uniformity and accuracy of the toward-target sprayer are improved, andthe pesticide applying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry machinery, and in particular relates to an air-driven variable target sprayer for terraced orchards and a target spray method. Background technique [0002] The forest and fruit industry is an important part of China's modern agriculture and forestry. By the end of 2013, the country's orchard planting area reached 12.8 million hectares 2 , the output reached 150 million tons, and the corresponding orchard pest control has become the most important and time-consuming operation in orchard management. The use of pesticides plays an important role in the control of fruit tree pests and diseases, and is currently irreplaceable. The control of orchard pests and diseases is mainly based on spraying chemical agents. However, in the traditional pesticide spraying technology for tree pests and diseases control, the adjustment accuracy of the spray distance between the nozzle and the targe...

Problems solved by technology

[0005] Chinese patent (CN110388225A) discloses an infrared random induction spray dust suppression system, through the detection system composed of external sensors, processors, CAN controllers, CAN transceivers and photoelectric isolators, using infrared sensors and pressure sensors to receive signals to judge Spraying time and spraying volume; this system is not effective in detecting the spraying of orchard plants in the field, the adaptability is not strong, and the recognition effect is not accurate enough

Chinese patent (CN110463672A) discloses the automatic spraying system of the orchard based on the single-chip microcomputer, and the wire sensor and the infrared converter are connected with the single-chip microcomputer, and the electromagnetic valve, the regulating mechanism and the swinging mechanism of the spray bar are arranged on the output end of the single-chip microcomputer, and are connected with the nozzle, In order to achieve the purpose of improving the utilization rate of pesticides and reducing labor intensity; however, the patent does not introduce the specific design of the control mechanism and the swing mechanism of the spray boom in detail

Chinese patent (CN104996387A) discloses a hand-push air sprayer, which uses a hand cart to carry out spraying operations, and uses a battery pack to supply power to the diaphragm pump. This small sprayer is used for the prevention and control of plant diseases and insect pests in tea gardens; For orchards, the spray volume and spray effect are not suitable, and the labor cost is high
