A direct injection real-time variable concentration online mixing spray device and its control method

Abstract

The invention relates to a direct injection type real-time concentration variation on-line pesticidesmixing spraying device. The device comprises a water supply through-line module, a precision amount pesticide supply through-line module, a pesticide mixing applying module and a control module. The water supply through-line module and the precision amount pesticide supply through-line module are both connected with the pesticide mixing applying module. The control module is connected with the water supply through-line module to collect the flow and pressure signals of the water supply through-line module. The control module is connected with the precision amount pesticide supply through-line module to control the amount of the pesticides entering the pesticides mixing applying module based on the flow, pressure and the pesticide mixing ratio of the water supply through-line module. Water and pesticides are mixed in the pesticide mixing applying module, and sprayed out in time. The invention further relates to a control method for the direct injection type real-time concentration variation on-line pesticidesmixing spraying device. In the applying process, the injection amount of a variety of pesticides is controlled in a real-time mode, and the injected pesticides are mixed uniformly online. The device can be installed on any pre-mixing spraying machine, and has a simple and reliable structure.

Description

technical field [0001] The invention relates to the technical field of intelligent agricultural machinery and plant protection machinery, in particular to a direct-injection variable spray device with real-time variable concentration and online drug mixing and a control method thereof. Background technique [0002] Crop diseases and insect pests are the main crop disasters in my country. They have the characteristics of various types, large impacts, and easy outbreaks. If they are not prevented and managed in time, they will cause great losses to our national economy, especially in the field of agricultural production. Therefore, strengthening crop field management is an important measure to build stable and high-yield farmland. The prevention and management of crop diseases and insect pests in the field have a great impact on the growth, development and yield of crops. At present, the policy of my country's plant protection work is "prevention first, comprehensive preventi...

AI Technical Summary

Problems solved by technology

While chemical pesticides suppress pests and diseases, many problems also arise: such as pesticide residues, environmental pollution and waste of resources caused by unreasonable use of pesticides

Therefore, the current online drug mixing device is limited by the liquid flow detection technology, drug mixing delay and suitability, etc., and it is difficult to meet the market demand
