Abstract

The utility model relates to a manual sprayer for paddy farms of a piston pump which is operated by a jiggle handle. The manual sprayer for the paddy farms adopts two piston pumps with large flow quantity to work in an alternation way. After clear water and medicine liquid are sucked into a pipe-shaped mixing device, the clear water and the medicine liquid enter the piston pump, are pressed into an air chamber from the piston pump, and then are sprayed out by way of a flexible pipe spray gun. The utility model has the advantages of simple structure, convenient operation, low cost and little water consumption. A person does not need to launch with spraying, and operational condition is improved. The utility model can be suitable for the spray of the paddy farms and can also be suitable for the spray work of other farmland operation and orchard.

Description

Manual sprayer for paddy field

The utility model is the sprayer about agricultural usefulness, in particular for the sprayer in paddy field.

Present widely used liquid pump formula sprayer (claiming hand-powered knapsack sprayer again), its primary structure is a spray tank, and a piston pump is set in spray tank.By the upper and lower motion of piston in the hand bar drive piston pump, soup is pressed into by outlet valve through water intaking valve sucker Beng ， And and is arranged on the other air chamber of spray tank.Soup transfusion sebific duct, switch and spray boom through being connected with air chamber outlet at bottom place under the approximate pressure stable of air chamber sprayed by shower nozzle.This kind sprayer, simple in structure, easy to manufacture, use easy to maintenance, cheap.But the finite capacity of its spray tank needs often to add soup; The piston pump flow is too little, and range is not far; Need the people bear mobile operating, difficulty in walking not only in the paddy field especially, and the trouble of being stung the liquid of sucking blood by leech is arranged, or by the sorrow of the metal in the rubbish base manure, glass injury.Three cylinder piston pump sprayers by various power drive work, piston pump is pressed into air chamber suck clear water from the paddy field after, the high pressure clear water that flows out from air chamber is introduced into jet type mixer, and the vacuum that denseer soup is caused by jet in the medical liquid container sucks jet type mixer and clear water is mixed into the soup of desired concn through delivery hose, spray gun ejection.The advantage of this kind sprayer is big, the far firing range of piston pump pressure height, flow; Water intaking on the spot reduces and adds soup number of times and spray tank volume; Operator and machine are in limit, the field operation walking of need not going to the field.But this three cylinder piston pump sprayers structure is complicated, and cost height, needs consume diesel oil, gasoline or electric energy.

The purpose of this utility model be to provide a kind of with manpower, only can operate and the walking that need not to go to the field, spray tank volume are little, far firing range, flow is big, expulsion pressure is stable manual paddy field sprayer on the limit, field.

The utility model is achieved in that a kind of manual paddy field sprayer that comprises plunger pump, air chamber, water intaking valve, outlet valve, base, crank handle, medical liquid container, flexible pipe and spray gun, it is characterized in that base is provided with two supports that keep at a certain distance away; The fulcrum of crank handle is hinged on the end of a support away from base; The liquid feeding end of two piston pumps is hinged on another support Shang ， And and above-mentioned two pin joints have certain distance in vertical direction; The other end of two piston pumps is hinged on the both sides of crank handle fulcrum respectively; The inlet of two piston pumps respectively links to each other with mixer for liquid by flexible pipe, and mixer for liquid one end is connected with the suction filter screen by flexible pipe, and the medical liquid container that is arranged on the base links to each other with mixer for liquid by flexible pipe.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the structural representation of the utility model piston pump.

Referring to Fig. 1, the utility model has a tabular base 3.Support 2 and 5 is screwed on base 3, And and be separated with certain distance each other.Crank handle 18 usefulness pins 1 are hinged on the support 2.Two identical piston pumps 4 of structure are brought the mouth of a river 26 and delivery port 27(into referring to Fig. 2) water inlet hinged with pin 19 and support 5, the other end of two piston pumps 4 then is hinged on respectively on the crank handle 18 of pin 1 both sides with pin 17.The pin 19 of two piston pumps 4 has certain distance in vertical direction.The water inlet 26 Shang ， And that two water intaking valves 10 are installed in piston pump 4 link to each other with the mixer for liquid 11 of tubulose by flexible pipe 9.Two outlet valves 15 are installed on the delivery port 26.Air chamber 14 is installed together ， And with an outlet valve 15 and links to each other with another outlet valve 15 by flexible pipe 16.Air chamber 14 is connected with spray gun 13 by flexible pipe 12 again.One end of mixer for liquid 11 is connected with suction filter screen 8 by flexible pipe 7.Also be provided with medical liquid container 6 on base 3, medical liquid container 6 usefulness flexible pipes link to each other with mixer for liquid 11.In medical liquid container 6 and pipeline that mixer for liquid 11 links to each other, be provided with the trunnion 28 or the metering-orifice of control medicinal liquid flow.

Fig. 2 is the structural representation of piston pump.One end of piston cylinder 21 has the extension part of bringing the mouth of a river 26, delivery port 27 and hinge hole 20 into.The other end of piston cylinder 21 is equipped with guide cover 22.An end that is positioned at the piston rod 23 of piston cylinder 21 is equipped with the leather cup 25 at two lip phase backs.The overhanging other end in hole that piston rod 23 passes guide cover 22 is provided with hinge hole 24.

When shaking crank handle 18, two piston pump 4 alternations, in mixer for liquid 11, be mixed into the soup of desired concn by suction filter screen clear water of from the paddy field, drawing and the soup that sucks from medical liquid container 6, this soup is further mixed by piston pump 4 Xi Ru And, be pressed into air chamber 14 by piston pump 4 again, after spray gun 13 ejections.

The piston of piston pump can also be the cylindrical metal piston that is provided with various rubber or metallic packing ring except that leather cup shown in Figure 2.

The utility model is owing to adopt the piston pump alternation of two big flows, so pressure is high and stablize far firing range. And the people need not to descend paddy field operation ， And to have water consumption few, simple in structure, need not power-equipment, the advantage such as cheap. The utility model not only is used for paddy field spraying work, still can be used for the spraying operation in other farmlands and orchard.
