Abstract

The utility model relates to a manual high pressure type sprayer used for the sprayof plant protection, epidemic prevention and spray construction, which aims at reducing labor intensity, extending the service life of a piston and increasing work efficiency. The utility model has the structure that elastic one-way valves are both adopted by a water outlet valve with a water inlet pipe 5 assembled on a horizontal type air storing chamber 9 and a water outlet valve on the lower end of a cylinder body, and the piston are assembled on a piston rod by a concave type pad bowl and nuts. The utility model has the advantages that the closing of the elastic valves is good, the frequency of reciprocating operation is 12 times / minute, spray quantity reaches 3 litres / minute, the center of gravity of the complete machine is lowered, the manual high pressure type sprayer is difficult to turn over, the human body is not easy to contact, and the use is convenient.

Description

Hand high-pressure sprayer

The utility model relates to the high pressure manual formula sprayer that is used for plant protection, epidemic prevention, spraying building spray wine.

In the background technology of the present utility model, sell non-motor-driven high-pressure sprayer on the market and have two kinds, a kind of is pedal, its weak point is: during cylinder body work is that pressured sealing cushion for cover, oil ring carry out isolating seal, if the V-seal pad leaks, must compress gland, so but increase the frictional force of cylinder body and sealing gasket, when causing work, labour intensity strengthens.Another kind is that ground is wheeled, its weak point is: do not allow to cylinder body and piston seal face apply oil, cause the coefficient of friction of rubber piston and metal cylinder body to increase, wearing and tearing increase, and service life is short, labour intensity is also big, and too high because of machine gravity, easily turn over machine when mobile, its pedal is fixed, not only not easy to store, and easily collide human body.Above-mentioned two kinds of sprayers are the rigidity valve, and the valve sealing is bad, and it is serious to reflux, and efficiency is not high.

The purpose of this utility model is the weak point that overcomes in the above-mentioned background technology, and a kind of high pressure manual formula sprayer is provided, and reaches to reduce labor intensity, improve rubber piston service life and efficiency, and reduces fault, purpose easy to use.

Technical solution of the present utility model is:

Assembling land wheel 8 and dismountable movable treadle 7 and depression bar 4 on the frame, cylinder body 2, water inlet pipe and water outlet pipe 5 and 10 are assemblied on the air receiver 9, its special character is, water inlet pipe 5 flowing water Valves of assembling adopt elastic one-way valve 6 on the horizontal air receiver 9, valve 6 is communicated with cylinder body 2 lower ends through pipeline, the flowing water Valve of cylinder body 2 lower ends adopts elastic one-way valve 6, and the piston 1 usefulness concave bowl 3 and the nut of work done are assemblied on the piston rod up and down in the cylinder body 2.

Technical solution of the present utility model also comprises:

Active foot plate 7 front ends have in steady pin 15 and the back plate 14 through hole edge one groove do to insert to extract out to cooperate, and movable block 13 usefulness removable pins 12 are assemblied on the header board 11, pedal 7 by movable block 13 and after plate 14 through holes assemble.

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

Fig. 1 is a front view.

Fig. 2 is a vertical view.

Number in the figure is described as follows:

The 1-piston, 2-cylinder body, 3-concave bowl, 4-depression bar, 5-water inlet pipe, 6-elastic one-way valve, 7-Active foot plate, 8-land wheel, 9-air receiver, 10-outlet pipe, 11-header board, 12-removable pin, 13-movable block, plate behind the 14-, 15-steady pin.

Embodiment of the present utility model is described as follows:

Referring to illustrated in figures 1 and 2, frame both sides assembling land wheel 8, horizontal air receiver 9 of assembling and dismantled and assembled movable treadle 7 on the frame, header board 11 and back plate 14 all are connected as a single entity with air receiver 9, the rotating piston block 13 of header board 11 usefulness removable pins, 12 assemblings, back plate 14 endoporus have a groove, be used for movable treadle 7 end steady pins 15 by assembling, make pin 15 respective slot, extract out and leave back plate 14 when treadle 7 rotates, treadle 7 is rotated, so that user's carrying, easy to operate up and down.Also assemble depression bar 4 on the frame, adopt the lever operation principle, make depression bar 4 usefulness wear pin and connect piston rod upper end in the cylinder body 2, manually depression bar 4 moves up and down, piston rod moves up and down thereupon, piston-rod lower end all adopts elastic one-way valve 6 with the also work done thereupon of piston 1 of concave bowl and nut assembling, the inlet valve of the flowing water Valve of cylinder body 2 lower ends and connection water inlet pipe 5, and valve 6 is made up of assembling rubber pad on the valve rod front end of suit in the stage clip.The complete machine operation principle is like this, when manual depression bar is about in the of 4, and piston work done about in the of 1, liquid medicine in the suction and pumping water inlet pipe 5 extrudes (ejection) liquid medicine with certain pressure, and liquid medicine sprays from outlet pipe 10 through air receiver 9.

Advantage of the present utility model and effect are:

1, owing to save gland and V-shaped seal ring, with concave bowl clamping rubber piston, but charging-up lubricant oil during work is saved component wear and is increased work efficiency.

2, the rigidity ball valve is feather valve owing to change in the past, and sealing is good, and the reciprocal number of operations of per minute is 12 times, is 40% of ground roller type or pedestal mounted sprayer number of times.

3, air receiver changes into horizontally by vertical, reduces machine gravity, turns over the phenomenon of machine when having avoided mobile.

4, because employing activity treadle so complete machine structure diminishes, is deposited conveniently, and it is little to take up space, and be difficult for the collision human body.

5, spray amount improves, and reaches 3L/min, and atomizer wheel improves 45%, and operating pressure improves 7.5%, improves 51.7% than pedestal mounted sprayer, and operating pressure improves 38.3%.
