Abstract
The utility model relates to a high pressure knapsack sprayer which is used for spraying liquid medicine for trees, fruit trees, and crops. The utility model is composed of a medicine barrel with a pair of harnesses, a liquid infusing pipe, a spray head, a spray rod, a ball valve switch, a high pressure bag. The convex part of a host machine barrel which is arranged on the upper part of a high pressure cylinder and a water filling opening on the host machine barrel are flat. A liquid returning hole which is communicated with the host machine barrel is arranged on the high pressure cylinder. The lower end of the high pressure cylinder is provided with a filtering screen, a skeleton is arranged in the filtering screen, and the outside of the filtering screen is inlaid with a filter screen. The utility model which further solves the problem that the liquid medicine is spayed out of a cylinder cap has the advantages of long service life and good sealing performance for a switch; in addition, because the skeleton is arranged in the filtering screen, and the filter screen is inlaid on the outside of the filtering screen, the utility model has the advantages of solving the phenomenon that the spray head is plugged at the time of work and effectively preventing poisoning.
Description
The utility model ridge of high pressure minus formula sprayer is a kind ofly can produce high pressure, and the outer sprayer that spatters soup has better spraying effect to a high crop especially.
China's sprayer commonly used can not produce high pressure during use at present, the shower nozzle atomization badness, and not good to a high crop spraying effect, the sealing of high pressure pump is bad, and soup spatters outward, uses very inconvenient.
The utility model improves according to above deficiency, and having reached soup can not spatter outward, can produce high pressure during operation, and medical liquid atomizing is good, to a high good high-pressure fog of crop spraying effect.
The design of the utility model sprayer is finished like this, high-pressure sprayer, comprise the explosive barrel of being with braces, the transfusion sebific duct is connected shower nozzle, spray boom, ball valve switch, high voltage package, high pressure pump position is installed, main frame bucket boss height and main frame bucket filler level, the penstock internal upper part has the hole for back flow that communicates with the main frame bucket.Water intaking valve communicates with water inlet screen pack and main frame bucket.The turnover water valve communicates with high voltage package.Piston, connecting rod, be connected with handle.
According to above-mentioned technical scheme, high pressure pump installation position main frame bucket exceeds the use water surface, and hole for back flow is arranged, so reach the purpose that soup can not spatter outward.The high pressure pump dwindles internal diameter, has thickeied the pump wall, has strengthened the ability of bearing pressure, so improved ejection pressure.High voltage package adopts buries a floating blow molding of part, does not have interface, can bear high pressure, so reached and the supporting purpose of high pressure pump.The sealing of ball valve switch is tight, and long service life is spattered short defective in service life outward so solved soup.In have skeleton to inlay filter screen outward, solved other shower nozzle phenomenon of blocking at work.
Accompanying drawing is the utility model front view.
Do with reference to the accompanying drawings below and describe in further detail.
High pressure is born sprayer, include the explosive barrel 15 of braces, woven hose 1 links to each other with spray boom 4 shower nozzle with high voltage package 8, there is filler 2 on the bucket top, it is characterized in that the main frame bucket protrusion position on high pressure pump 9 tops and filler 2 levels of main frame bucket 15 are installed, the hole for back flow 6 that communicates with the main frame bucket is arranged on the high pressure pump 9; There is screen pack 14 high pressure pump 9 lower ends, and screen pack 14 has skeleton to inlay filter screen outward in being.Pump cap 5 is equipped with on high pressure pump 9 tops, and water intaking valve 11 is equipped with in the bottom, and outlet valve 10 communicates with high voltage package 8.High voltage package 8 is buried a floating blow molding of part, and high voltage package is connected with ball valve switch 3, spray boom 4 spirals by sebific duct.Piston 13, connecting rod 7 link to each other with handle 12.
