Novel pesticide spraying device

Abstract

The invention provides a novel pesticide spraying device, which comprises a spraying head and a barrel body. The spraying head comprises an atomizing chamber; a plurality of atomized medicine liquid through holes are formed in the conical side face of the atomizing chamber; a spacer is also arranged in a conical structure; a trumpet-shaped pesticide guiding port is also formed in the atomizing chamber; a medicine liquid storage cavity and a gas compression pump are arranged in the barrel body; the gas compression pump is communicated with the inlet end of a high-pressure air flow channel; the outlet end of a medicine liquid output pipe and a high-pressure air flow nozzle connected with the outlet end of the high-pressure air flow channel are arranged side by side; the outlet end of the medicine liquid output pipe and the high-pressure air flow nozzle simultaneously stretch into the atomizing chamber and opposite to the spacer; the high-pressure air flow channel is also communicated with the air inlet end of an air guiding channel; the discharge end of the air guiding channel is located above a medicine liquid level in a medicine liquid storage cavity; an electric reducing valve is arranged on the discharge end; a power module and a controller are also arranged in the barrel body; the controller is in signal connection with the gas compression pump and the electric reducing valve. According to the novel pesticide spraying device provided by the invention, the pesticide spraying atomization efficiency can be improved, so that the pesticide spraying efficiency is improved.

Description

technical field [0001] The invention relates to the field of agricultural production tools, in particular to a novel pesticide spraying device. Background technique [0002] In the process of spraying pesticides to crops in the existing pesticide spraying device, the atomization rate of the sprayed pesticide solution is not high. The reason is mainly due to the low internal pressure of the pesticide spraying device and the unreasonable structure of the pesticide spraying head. due to. [0003] The low atomization rate of pesticide spraying not only leads to waste of pesticides, but also leads to incomplete spraying of crops on leaves. If the spraying rate of pesticides is not high, the pesticides will be mainly sprayed on the upper surface of the leaves, and the excess liquid on the leaves will be lost, so that the pesticides cannot be fully utilized and cause waste. And if the atomization rate is high, the sprayed pesticide mist can fully surround the crop leaves during t...
