Description
Technical field
The utility model relates to agricultural machinery technological field, and more particularly, it relates to a kind of knapsack sprayer.
Background technology
Knapsack sprayer is extensively with ten all kinds of crops at present, orchard herbal sprinkling and diseases and pests controlling and public places sanitary epidemic prevention, sterilization: particularly in wide rural area, peasant is used for spraying insecticide to large stretch of rice field or mountain forest: knapsack sprayer is easy to carry, with it mostly operator is to be born, switch on power after switch and can use, but with it will being born during because of operation, knapsack sprayer in prior art, comprise liquid receiver, pressue device, described liquid receiver top is provided with sealable filling opening, the bottom of liquid receiver is provided with liquid outlet, the drain pipe being connected with liquid outlet, the spray gun being connected with drain pipe, after operation a period of time, operator easily perspires and feels tired, hot weather in full summer particularly, when working on the Jian Huo mountain ridge, field, because of the as easy as rolling off a log generation heatstroke phenomenon not in time of preventing heatstroke and lower the temperature, and this sprayer, heat abstractor is not set between liquid receiver and human body back, do not there is radiating and cooling effect and the damp proof effect to human body back.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of knapsack sprayer, and this knapsack sprayer has advantages of radiating and cooling, damp proof to human body back, can avoid staff to occur the phenomenon of heatstroke.
For achieving the above object, the utility model provides following technical scheme: a kind of knapsack sprayer, comprise liquid receiver, pressue device, described liquid receiver top is provided with sealable filling opening, the bottom of liquid receiver is provided with liquid outlet, the drain pipe being connected with liquid outlet, the spray gun being connected with drain pipe, the face that described liquid receiver contacts with human body back forms installed surface, described installed surface is provided with depressed part, in described depressed part, be provided with at least 2 heat abstractors, described heat abstractor includes impeller, power supply, the motor being connected with power supply, described depressed part opening part is provided with protective cover, described protective cover is provided with several air-vents, described impeller is connected with motor output end, the other end of the relative output of described motor is connected with installed surface.
By adopting technique scheme, at installed surface, depressed part is set, heat abstractor is set in depressed part, driven by motor wheel rotation, air-flow blows by the air-vent being arranged on protective cover the effect that not only reaches damp proof to human body back to the back of human body, but also play the effect of radiating and cooling, can avoid staff to occur the phenomenon of heatstroke.
The utility model is further set to: described depressed part is groove, and described groove forms air inlet along extending liquid receiver bottom.
By adopting technique scheme, in liquid receiver bottom, air inlet is set, can provide sufficient origin for heat abstractor, further improve radiating and cooling, the damp proof effect of human body back.
The utility model is further set to: the quantity of described heat abstractor is two.
By adopting technique scheme, the quantity of heat abstractor is arranged to 2, can further improve radiating and cooling effect and the effect damp proof to human body back.
