Automatic targeting and spraying system

Abstract

The invention discloses an automatic targeting and spraying system. The automatic targeting and spraying system comprises an all-directional moving platform, an image acquisition device, a spraying device and a control device are mounted on the all-directional moving platform, and the control device is used for receiving and analyzing crop image information outputted by the image acquisition device and controlling operations of the spraying device and the all-directional moving platform; the spraying device comprises a drug container, a liquid outlet pipe, a delivery pump and a mechanical arm, one end of the liquid outlet pipe is communicated with the drug container while the other end of the liquid outlet pipe is connected with a spraying rod, a plurality of nozzles are fixed onto the spraying rod, the delivery pump is mounted on the liquid outlet pipe and used for pumping fertilizer or pesticide from the drug container into the liquid outlet pipe, and the spraying rod is fixed onto the mechanical arm; the image acquisition device comprises a CMOS (complementary metal oxide semiconductor) camera and a distance sensor, the CMOS camera and the distance sensor are fixed onto the mechanical arm. Since the CMOS camera, the distance sensor and the spraying rod are mounted on the mechanical arm, all-directional image acquisition of crops can be completed while pesticide or fertilizer can be sprayed on the crops intensively in all directions, and accordingly pesticide or fertilizer utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an automatic target spraying system. Background technique [0002] Pest control is an important part of the crop planting process. In China, nearly 80% of pesticide application operations still use manual sprayers to spray pesticides on crops in a large area. The pesticide application method is simple and extensive, and the phenomenon of "running, dripping, dripping, and leaking" is serious, and the utilization rate of pesticides is only about 20%, which causes serious waste and environmental pollution, and also affects the sales, consumption and export of crops. Every year, there are many pesticide poisoning incidents caused by pesticide application. It is imperative to develop pesticide application systems and methods that can effectively control the development of pests and diseases, ensure the ecological environment, and improve the utilization rat...

Problems solved by technology

But there are still some problems: First, the laying of guide rails increases the cost.

[0006] Second, the application environment is limited to hedge plants planted in the greenhouse; third, because the robot of the pesticide application system is suspended on the guide rail, the weight of the robot will cause deformation of the guide rail and the mechanical arm, resulting in a certain error, and Errors may accumulate, which will affect the precision and accuracy of spraying
