Description
Technical field
The utility model relates to a kind of sprayer, relates in particular to that a kind of piston rod action of water drawing device is smooth and easy does not worry seepage, and the agricultural manpower back-pack smei antomobile sprayer that improves of practicality and ease of use.
Background technology
Agricultural manpower back-pack smei antomobile sprayer is often used in spraying insecticide in rice field, orchard or the woods, fertilizer and water etc., spray evenly owing to have on it uses, can carry on the back during operation and wear and tool mobility, and various spray agents of splendid attire according to need, so be the indispensable utensil of agro-farming work.
As Fig. 1,2,3, shown in 4, be a kind of existing agricultural manpower back-pack smei antomobile sprayer, it is by a water drawing device B is set in the container A, water drawing device B upper end passes the container A end face and connects a rocker arrangement C and a flusher D, this water drawing device B comprises that group is established a piston rod 20 in the valve cylinder 10, the rocker arrangement C that cooperates the outside is by pressure-controlled, to reach extrusion effect via built-in piston end, make the effect of inner tool supercharging gasification, a pressure storage tube 30 is fixed in the welding of valve cylinder 10 sides, valve cylinder 10 upper ends are arranged in a metal fixed head 40 default circular hole 401 interior welding and fix, and on the spiro union portion 402 that these circular hole 401 peripheries are convexly equipped with a sheathed interlock ring 403, fix with a locking ring 404 and the sheathed lock nut 201 lock knots of piston rod 20 outer rims again, valve cylinder 10 bottoms are provided with a feed liquor valve 50, brace 3011 welding of lower end one side and pressure storage tube 30 bases 301 are fixing, and the welding one syphon shape liquid valve 60 that is communicated with between lower end and pressure storage tube 30 bottoms, it is fixing that pressure storage tube 30 upper ends are set in the welding of fixed head 40 bottom surfaces, the screw 405 default with fixed head 40 opposite sides is corresponding, and supply output duct 70 insert groups that have edge clipping 701 and be arranged with a ring spacer 702 in pressure storage tube 30 with this screw 405, it is fixing to cooperate hand-screw nut 703 to be spirally connected.
Whereby, piston rod 20 tops and interlock ring 403 articulate with rocker arrangement C, output duct 70 is connected with flusher D, and by rocker arrangement C piston rod 20 knee-actions, make liquid in the reciprocal supercharging gasification vessel of piston end 10 to pressure storage tube 30, and be able to spray with vaporific by flusher D through output duct 70.
But aforesaid existing agricultural manpower back-pack smei antomobile sprayer when practical application, has following shortcoming:
