Abstract

The utility model relates to a sprayer from which liquid can be obtained by that an operator controls a floating piston in a pressure container, comprising a base, an air chamber, a piston cylinder, a nonreturn valve and a transmission device; the air chamber, the piston cylinder and the nonreturn valve are installed on the base; a piston is controlled to do upward and downward movement by the transmission device which is composed of a piston rod, a draw rod, a pressure bar fork and a handle. The utility model is characterized in that a conical top surface is arranged on a leather cup. An oil filling hole is arranged on a pressing cover. Therefore, lubrication oil can be supplemented to reduce the friction of the leather cup. The utility model has the advantages of convenient maintenance, reliable work, quick water feeding, high pressure, long service life, etc., and is particularly suitable for preventing and curing the insect pest of fruit trees, mulberries and woodland gardens.

Description

The pressure lever type high-pressure sprayer

The utility model relates to a kind of injection apparatus of discharge liquid, is particularly obtained the sprayer of liquid by the floating piston in operating personnel's controlled pressure container.

Existing single cylinder 28 type compression sprayers, because lubricating oil is in time in the input piston tube, piston cylinder and leather cup friction will increase, cause piston to be difficult to pulling, the phenomenon that leather cup damages easily, and this sprayer keeps in repair, changes other parts inconvenience, cost height.

The purpose of the utility model is to provide a kind of both long service life, easy to maintenance, goes up water piece, console mode sprayer that pressure is high again.

The purpose of the utility model is realized by following technical scheme: it comprises support, be fixed on and bring the pedestal that water is chewed on the support into, be contained in air chamber and piston cylinder on the pedestal, place piston cup and piston rod in the piston cylinder, the piston rod top is connecting pull bar, the other end of pull bar is connected depression bar and sticks, the prong dead axle of depression bar fork is fixed on the pedestal, the other end is connecting handle, on pedestal and the air chamber water inlet check valve is housed, leather cup has put a garden vertex of a cone face, and the gland of garden vertex of a cone face has oil filler point relatively.

Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

The pressure lever type high-pressure sprayer comprises the support 21 that has roller 20, is fixed on to bring water on the support 21 into and chew 19 base 18, is contained in piston cylinder 10 and air chamber 7 on the base 18.The water inlet of base 18 is chewed 19 and is communicated with air chamber 7, piston cylinder 10, and the water inlet of air chamber 7 is provided with check valve 6, on air chamber 7 diapires water outlet is housed and chews 8; Check valve 6 between chewing 19, is housed in base 8 and water inlet, gland 9 and the piston rod 11 that passes gland 9 are housed on the piston cylinder 10, piston 15 is being fixed with nut 17, packing ring 16 in the bottom of piston rod 11, the piston 15 outer leather cups 14 that are with, leather cup 14 cooperates with piston cylinder 10 inner wall sealings, the end face of leather cup 14 is the garden conical surface, has 2 oil filler points on the gland 9 of garden vertex of a cone face relatively, and thread plug 22 is arranged on the oil filler point.The other end of piston rod 11 is fixed on the pull bar 24 with pivot pin 1 and latch 23, and pull bar 24 is connected the centre of depression bar fork 5, and an end of depression bar fork 5 also is fixed on the base 18 with pivot pin 1 and latch 23 dead axles, and the other end is twisted with bolt 12 and decided handle 13.

Hang on the gland 9 of piston cylinder 10 outsides and also have 2 or 3 fixing holes, screw rod 4 passes fixing hole and with nut 3 piston cylinder 10 is fixed on the base 18, and gland 9 is fixed on the piston cylinder 10.

Operation principle of the present utility model is such: piston 15 is under the shaking of handle 13, by the transmission of depression bar fork 5, pull bar 22, piston rod 11.Generation moves up and down.When moving on the piston 15, the pressure in the piston cylinder 10 reduces, and the check valve 6 that water inlet is chewed on 19 is open-minded, and the closed check valve on the air chamber 7 at this moment, sucks water in the piston cylinder 10; When piston 15 moved down, the check valve 6 that water inlet is chewed under 19 was closed, and the check valve 6 on the air chamber 7 is open-minded, and the water in the piston cylinder 10 is pressed in the air chamber 7.Piston 15 is successive like this, periodically move up and down, and the water in the air chamber 7 just are filled, and produce bigger pressure, thereby reach the purpose that sprays water with high pressure.

The utility model is owing to have oil filler point on the gland 9 of piston cylinder 10, the lubricating oil that enter in the piston cylinder 10 can flow to the rubbing surface of leather cup 14 by the taper end face of leather cup 14, thus can make things convenient for, make-up oil in time, reduced the friction of leather cup 14.

Obviously, the utility model is simple in structure, and is easy to maintenance, reliable operation, be used as power without motor, therefore, be not subjected to the restriction of workplace, move light, last water is fast, the pressure height, and the life-span is long, except that can be used for fruit tree, mulberry tree, the wooden land prevention and control of plant diseases, pest control, also can be used for storage, deinsectization, health and epidemic prevention, building and whitewash etc.
