Abstract
The invention relates to a windproof spray head, wherein a sealed protective cover is sleeved outside an inner spray head, an inlet and outlet connecting pipe of the inner spray head extends out of the protective cover, a plurality of through holes are formed in the periphery of the bottom surface of the protective cover, the surface of the inner spray head with a nozzle is fixed on the bottom surface of the protective cover, the nozzle is surrounded by the through holes, and the protective cover is communicated with a high-pressure air source. Compared with the prior art, the invention has the following obvious advantages: the high-pressure gas is sprayed out from the through holes around the nozzle to form an air curtain, so that the liquid medicine sprayed out from the nozzle is protected from being influenced by other air flows.
Description
Technical Field
The invention relates to the technical field of pesticide spraying, in particular to a pesticide sprayer.
Background
When spraying insecticide because the effect of surrounding air current or wind-force, often can blow the liquid medicine that sprays to other places, can not effectual attached to on needing crops, great reduction the utilization ratio, cause a lot of unnecessary extravagants.
Disclosure of Invention
The invention aims to provide a windproof spray head aiming at the defects of the prior art.
The purpose of the invention is realized by the following technical means:
the outer surface of the inner spray head is sleeved with a sealed protective cover, an inlet and outlet connecting pipe of the inner spray head extends out of the protective cover, the periphery of the bottom surface of the protective cover is provided with a plurality of through holes, the surface of the inner spray head with a nozzle is fixed on the bottom surface of the protective cover, the nozzle is surrounded by the through holes, and the protective cover is communicated with a high-pressure air source.
In a preferred scheme, the top end of the protective cover is provided with a vent pipe.
Compared with the prior art, the invention has the following obvious advantages: the high-pressure gas is sprayed out from the through holes around the nozzle to form an air curtain, so that the liquid medicine sprayed out from the nozzle is protected from being influenced by other air flows.
Drawings
FIG. 1 is a schematic structural view of the present invention; fig. 2 is a top view of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following description and specific embodiments, taken in conjunction with the accompanying drawings, in which: in the figure, 1 inner spray head, 101 inlet connecting pipe, 102 outlet connecting pipe, 2 protective cover, 201 connecting pipe, 202 through hole and 3 vent pipe.
As shown in the figure, the windproof spray head is characterized in that a sealed protective cover 2 is sleeved outside an inner spray head 1, an inlet connecting pipe 101 and an outlet connecting pipe 102 of the inner spray head 1 extend out of the protective cover 2, a plurality of through holes 202 are formed in the periphery of the bottom surface of the protective cover 2, the surface of the inner spray head 1 with a nozzle 103 is fixed on the bottom surface of the protective cover 2, the nozzle 103 is surrounded by the through holes 202, and a connecting pipe 201 is arranged at the top end of the.
When the sprayer is used, the plurality of sprayers are connected in series, the inlet connecting pipe of the No. 1 sprayer is connected with the liquid medicine pump, the outlet connecting pipes 102 of other sprayers are connected with the inlet connecting pipe 101, finally, the outlet connecting pipes 102 of the sprayers are sealed, the vent pipe 3 of each sprayer is connected with the high-pressure air pump, liquid medicine sprayed from the nozzles is surrounded by air flow sprayed from the through holes, and the influence of surrounding air flow on the liquid medicine is reduced.
