Description

The back-pack electric sprayer

Technical field

The utility model relates to the back-pack electric sprayer, mainly is applicable to the control of damage by disease and insect such as orchard, gardens, flowers, booth, grain, belongs to agricultural plant protection machinery.

Background technology

Present most popular sprayer is to be born by the operator, with the manual sprayer of rocking bar operation liquid pump, the shortcoming of its existence is that people are more tired when operating, and should bear a heavy burden, the operating grip spray boom adopts battery-driven power spraye so developed in recent years again.Described power spraye is except that prior arts such as medicinal liquor barrel, spray boom, spray gun, base of specialized designs (electronic case) also, electric pump, battery and controller etc. are installed in the base, prior art is when final assembly, at first pump, battery and controller are installed in the base, then base and electrical components are connected the medicinal liquor barrel bottom together, when needing repairing or change battery, must remove whole base, therefore, the shortcoming of its existence: the one, need special-purpose position bulging staving in the junction of medicinal liquor barrel and base, make the machine volume heaviness; The 2nd, staving and base do not turn-over, and installation and maintenance are pretty troublesome; The 3rd, because the base bulging backs on the body and has contacted sense of discomfort with human body; The 4th, prior art adopts piston pump, and volume is big, Heavy Weight, and power consumption is big.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of base volume little, and the soup staving is connected dexterous with base (electronic case), and it is convenient that electric pump, battery etc. are installed repair and replacement, and pump is light, the back-pack electric sprayer that power consumption economizes.

The technical scheme of the utility model back-pack electric sprayer is: a staving of containing soup is arranged, staving connects base down, be shaped on inlet on the staving, battery and electric pump are installed in the base, the import of pump connects feed tube, feed tube leads in the staving, delivery side of pump connects woven hose, woven hose connects Switch of spray pistol, spray boom and shower nozzle, it is characterized in that the bottom of staving is shaped on the connecting ring of bulging, described base is shaped on bulge loop and inwall is shaped on fixed head in external wall of upper portion, the periphery size and the shape of bulge loop and connecting ring are consistent, and bulge loop has weld layer to link to each other with the connecting ring end face, is shaped on the bottom joint pin below fixed head, the electric pump fixed leg, the battery dead lever, in the electric pump bottom brace is housed, brace is connected by securing member with the electric pump fixed leg, is shaped on the connection ear at the edge of battery case, connects ear and battery dead lever and fixes, bottom at base connects bottom, and bottom links to each other with the bottom joint pin by securing member.

Compared with the prior art back-pack electric sprayer of the present utility model, has following characteristics: the one, and the connecting ring of staving bottom links to each other through weld layer with the bulge loop both ends of the surface of base, becomes as a whole, has both dwindled volume, and closure is good, and external form is attractive in appearance again; The 2nd, be shaped on fixed head and each fixture at base inner wall, so when mounted, can be inverted staving, be base last, bung is placed on corresponding position (corresponding recess is arranged) on the base to battery case and electric pump respectively down, and battery case and electric pump be connected ear and brace is linked to each other with dead lever, fixed leg by securing member, the location is very accurate and be difficult for displacement, by screw, spacers, bottom is fixed on the base seals at last.During maintenance,, just can directly take out battery and electric pump as long as unload lower bottom cover, simple to operation.

Back-pack electric sprayer of the present utility model, its described electric pump is the miniature diaphragm pump, weight is lighter, reduce operator's burden, and spray pressure is big, helps the sprinkling to tall and big fruit tree.In the inlet of its staving screen pack is installed, is guaranteed to enter pump soup interior and shower nozzle and be as good as grain etc.
