Description

Single pipe high pressure sprayer

The utility model relates to a kind of sprayer, and particularly a kind of push-and-pull is light, continuously the single tube high-pressure sprayer of spraying.

Existing single-tube sprayer all adopts the pump type structure, sprayer must be put into explosive barrel when utilizing vacuum to realize spraying thereby use, fragile explosive barrel, and operation effort, inconvenient maintenance, the replacement of consumable accessory is more difficult, moreover general similar sprayer air pressure is not high, and liquid medicine is penetrated high less, spray medicine inconvenience to forest, fruit tree and other long-stalked crop disease and pest, in addition owing to all adopt metallic element, easily get rusty or corrode, directly influence the service life and the cost of sprayer.Disclose a kind of Straight pull three valve sprayers in CN2076454U, it only is fit to spraying among a small circle, to forest, the contour bar crop spraying medicine of fruit tree weak effect.

It is long that the purpose of this utility model designs a kind of life-span exactly, and operating maintenance is the single tube high-pressure sprayer easily.

The purpose of this utility model realizes by following structure: the single tube high-pressure sprayer includes shower nozzle, playpipe, flexible pipe and the piston rod of taking water valve out of, bring the piston sleeve of water valve and outlet valve into, pressure tank and filter-tipped water inlet pipe, its principal character is: the push-and-pull action bars that a control piston bar is arranged on the piston rod outside pressure tank, lower end at pressure tank is connected to a lower end pin by seal cover, during use, as long as the water inlet pipe in the pin of lower end is inserted in the explosive barrel, push-and-pull action bars liquid medicine just can spray continuously from nozzle high-voltage, to forest, fruit tree and other long-stalked crop disease and pest spray medicine.

The utility model compared with prior art has simple in structure, and is easy to use, and the laborsaving wind advantage of action bars push-and-pull especially is fit to forest, and fruit tree is used during contour bar crop spraying medicine.

Description of drawings of the present utility model is as follows:

Fig. 1 is the utility model structural representation;

Fig. 2 is the low pressure shower nozzle.

Among the figure: 1, low pressure shower nozzle, 2, high-pressure nozzle, 3, coupling head, 4, playpipe, 5, handle, 6, switch, 7, flexible pipe, 8, hose coupling, 9, Discharging bent-tube, 10, action bars, 11, stop collar, 12, coupling nut, 13, sealing ring, 14, nut, 15, upper end cover, 16, top cover labyrinth, 17, outlet valve, 18, piston rod, 19, glass marble, 20, outlet valve, 21, the suction leather cup, 22, steadying plate, 23, water intaking valve, 24, lower sealing cover, 25, lower end pin, 26, articulation, 27, the water inlet bend pipe, 28, filter tip, 29, piston sleeve, 30, pressure tank.

The utility model will be further described below in conjunction with drawings and Examples.

As shown in Figure 1: the utility model includes the playpipe 4 of band high-pressure nozzle 2 or low pressure shower nozzle 1, flexible pipe 7 and the piston rod 18 of taking water valve 20 out of, bring the piston sleeve 29 of water valve 23, outlet valve 17 into, the water inlet pipe of pressure tank 30 and band filter tip 28, one push-and-pull action bars 10 is arranged on the piston rod outside pressure tank, be connected to a lower end pin 25 by lower sealing cover 24 in the lower end of pressure tank.For easy to use, the flow velocity and the range height of medicine sprayed in control arbitrarily, and push-and-pull action bars 10 can be a T type bar, and can be connected to a switch 6 on playpipe or flexible pipe 7, for in use piston rod and piston sleeve are stable, the steadying plate 22 of an intrinsic piston sleeve in pressure tank; In order to reduce production costs, increase the service life, the parts of this sprayer all adopt working of plastics to replace the metalwork that is subject to the liquid medicine corrosion in the general sprayer.
