Automatic liquid chemical filling machine of plant protection unmanned plane

Abstract

The invention discloses an automatic liquid chemical filling machine of a plant protection unmanned plane. The automatic liquid chemical filling machine comprises a water feeding device, a storage device, a chemical tank device and a liquid outlet device. The water feeding device comprises a water sucking pipe, a micro pump and a program-controlled controller. The storage device comprises a box and a stirring mechanism arranged in the box. The liquid outlet device comprises an intelligent driver, a guide pipe and a quantifier filling device. The water sucking pipe is connected with an external water tank. The program-controlled controller controls the micro pump to pump water into the box of the storage device. The stirring mechanism stirs liquid chemicals, addition agents and water added into the box, so that mixed liquid is formed. The mixed liquid is driven by the intelligent driver to enter the guide pipe. The quantifier filling device is provided with an oil injection nozzle, a quantifier and a switch controlling the oil injection nozzle. The quantifier filling device controls the oil injection nozzle to stop adding liquid when the quantity of liquid chemicals added into a chemical tank of the unmanned plane reaches a specific level. The specification of the added liquid chemicals is adjusted at any time by additionally arranging the intelligent driver, waste of the liquid chemicals in the filling process is avoided, the automatic liquid chemical filling machine is simple and practical, and manpower and material resources are greatly saved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle liquid filling, in particular to an automatic liquid filling machine for plant protection unmanned aerial vehicles. Background technique [0002] When the existing plant protection unmanned helicopters in the field of aircraft are filled with liquid medicine, they are all filled manually, which requires the division of labor and cooperation of many people to complete. The man-machine runs anytime and anywhere. After the plant protection drone lands stably, move all the relevant things in place, mix the water, liquid medicine, and additives together, and use the corresponding things to stir the mixture evenly, and then put the Pour the mixed medicine into the medicine box of the plant protection drone. This is very inconvenient for the person who pours the medicine. The way can't be done accurately, either the medicinal liquid is not enough or there will be a surplus of medicinal l...

[0002] When the existing plant protection unmanned helicopters in the field of aircraft are filled with liquid medicine, they are all filled manually, which requires the division of labor and cooperation of many people to complete. The man-machine runs anytime and anywhere. After the plant protection drone lands and stabilizes, move all the relevant things in place, mix the water, liquid medicine, and additives together, and use the corresponding things to stir the mixture evenly, and then put the Pour the mixed liquid medicine into the medicine box of the plant protection drone. This is very inconvenient for the person who pours the liquid medicine. The method cannot be done accurately, either the liquid medicine is not enough or there will be a surplus of liquid medicine, causing unnecessary waste, and in addition, poisoning incidents of people pouring the liquid medicine will also occur

For small plant protection drones, it doesn’t need too much water, and manual handling is not too laborious. Like the current large plant protection drones, when the volume of the hanging cartridge reaches 60L or even larger, it is very laborious and troublesome to carry it manually.
