Description

Electrostatic spray equipment and work car with electrostatic spray equipment

Technical field

The utility model is related to an electrostatic spray equipment, especially a kind of electrostatic spray equipment for agricultural spray operation With the work car with electrostatic spray equipment.

Background technology

What is be commonly used in traditional agricultural spray work is the mode of Direct spraying.After atomizing the liquid into, it is sprayed on work On object, general pesticide is often in this way.

But because the liquid of atomization can be affected by gravity, left directed along the surface of blade or stalk, So the liquid fraction that can be used effectively is not high.It does not have not only for crop and timely operates, such as because pesticide It is insufficient and insect pest is caused to spread, and be also huge test for the cost of liquid.Because agriculture scale is whether great or small, all it is Complete spray operation according to a certain percentage.
