Abstract

The utility model discloses a novel portable manual sprayer. A pressure applying cylinder is fixed in the middle in a bucket with a shoulder strap, and a plunger of the pressure applying cylinder extends out of the top of the bucket to be connected with the lever-typed pressure applying cylinder fixed on the top of the bucket; a pressure storage cylinder is arranged beside the pressure applying cylinder; a one-way valve at the inlet position of the pressure applying cylinder is communicated with the inner side of the bucket, and a one-way valve at the outlet position is connected with the inlet of the pressure storage cylinder in which a suction pipe is arranged; one end of the suction pipe passes through a sealing opening of the pressure storage cylinder to be communicated with a pipeline reaching a spray head out of the bucket. The spray head is arranged on the top of a transfusion rigid pipe, one end of which is connected with a handle with a switch; a hose is connected between the handle and the suction pipe. Compared with the existing sprayer, the utility model changes the external leakage into the internal leakage, which avoids the pesticide waste and poisoning created by the leakage. The pressure storage capacity is also increased, the work efficiency is caused to be enhanced, and labor intensity is decreased. In addition, the operating position of a pressure applying rod becomes high, the crops can not be impacted, which causes the operation to be smooth.

Description

A kind of novel sprayer

The utility model relates to a kind of portable manual sprayer.

Now be widely used in agricultural and control the portable manual sprayer of worm, it is the side setting cylinder of exerting pressure outside the staving of a band braces, the piston rod of cylinder of exerting pressure connects an action bars of exerting pressure that can move up and down, a check valve is respectively established in the exert pressure import and the exit of cylinder cylinder body, communicate in import department's check valve and the bucket, the exit check valve links with the pipeline that arrives shower nozzle.In order to accumulate atomisation pressure, on described pipeline, be provided with a spherical accumulator that communicates with pipeline, this accumulator is positioned at the outer top of staving, just in time is in the occipital position of people's back sprayer barrel.The sprayer of said structure is exerted pressure cylinder and accumulator outside bucket, adopts thread seal by interface thereon, under pressure state, leakage is often arranged.The soup that leaks is directly trickled down on spray medicine people's body, accumulator place particularly, and toward dirty, entire back is all soaked has expired agricultural chemicals to the liquid medicine of constantly gushing out along people's collare.This has not only caused waste, more seriously causes poisoning.Exerting pressure, to place outer another defective that is produced of bucket be that because the restriction of volume, they can not do very greatly for cylinder and accumulator, thereby the soup reserves that pistons work is once obtained are less, for the continuous spray of executing, just to have to frequently, operate the bar of exerting pressure continuously, the muscle power that the people is paid is bigger.Aspect in addition, the action bars of exerting pressure be expanding-contracting action up and down at the sagging place of people's arm, because the position is too low, the collision crops make that to execute spray very not smooth.

The purpose of the utility model is to propose a kind of novel sprayer, and the problem of above-mentioned several configuration aspects in the existing sprayer is improved.

The technical solution of the utility model is, the middle part cylinder of fixedly exerting pressure in the staving of band braces, its piston rod stretches out the bucket top, link to each other with a lever that the is fixed in bucket top bar of exerting pressure, the other storage cylinder pressure of existing side by side of the cylinder of exerting pressure, exert pressure cylinder import department check valve with the bucket in communicate, its exit check valve links to each other with the import of storage cylinder pressure, the built-in suction pipe of storage cylinder pressure, the seal that suction pipe one end passes the storage cylinder pressure communicates with the outer pipeline that arrives shower nozzle of bucket, shower nozzle is installed in the top of transfusion hard tube, and the other end of this pipe links to each other with the handle of a belt switch, is connected a flexible pipe between this handle and the suction pipe.Behind the back sprayer barrel, the drop-down bar of exerting pressure that stretches to the human body shoulder, piston stroking upward, the cylinder cylinder body volume of exerting pressure increases, the bucket inner liquid medicine under pressure differential, enter in the cylinder by its import department's check valve, on push away the bar of exerting pressure, descent of piston, the cylinder body inner liquid medicine is squeezed in the storage cylinder pressure by its exit check valve under pressure differential, above repeatedly operation after storage cylinder pressure internal pressure reaches certain value, is opened the switch at shower nozzle front hand grip place, soup just is pressed towards shower nozzle, sprays through nozzle atomization.

The utility model is because the cylinder of will exerting pressure places the interior external leakage that becomes of bucket to be internal leakage with the storage cylinder pressure, and waste and the drug poisoning of having avoided leakage to cause have also increased storage pressure-volume amount simultaneously, and operating efficiency is improved, reduction labour intensity; The cylinder position sidesway outside bucket of exerting pressure uprises the operating position of the bar of exerting pressure that links to each other with piston to the bucket middle part, does not bump with crops, and operation becomes smooth.

Below in conjunction with the accompanying drawing embodiment that has a talk.

Accompanying drawing is depicted as the vertical sectional structure of the utility model.

Make and staving 14 that human body back roughly coincide, irritate, do not spill for making in bucket the fashion of falling the medicine, dash have the bucket top of irritating mouthful with respect to the edge of bucket wall to sinking one segment distance, enclose with formation and to block.The check valve 13 that will have the breach base is loaded on the import department of cylinder 11 bottoms of exerting pressure, near this import department, check valve 12 by a band elbow valve seat connects the outlet of the cylinder of exerting pressure and the import of storage cylinder pressure 6 bottoms, make the cylinder of exerting pressure become as a whole with the storage cylinder pressure, this integral body is put into bucket 14, it is lock onto the bucket top with gland 15.The exert pressure resistance arm of bar 9 of lever is fixed on the gland 15 around the bar alive by connective pole 8, and its fulcrum links to each other with the piston rod top, the bar 9 and exert pressure to add between the cylinder 14 and compress spring 10 of exerting pressure.Suction pipe 7 inserts in the storage cylinder pressure by the seal at storage cylinder pressure 6 tops, and the outer end of cylinder connects handle 4, transfusion hard tube 2 and the shower nozzle 1 of flexible pipe 5, belt switch 3 successively.

Claims (2)

1, a kind of novel sprayer, staving with band braces, the cylinder of exerting pressure, the storage cylinder pressure, the bar of exerting pressure, pipeline, switch, shower nozzle, exert pressure cylinder import and exit respectively is provided with check valve, it is characterized in that, the described cylinder of exerting pressure is fixed in medium position in the staving, its piston rod stretches out the bucket top, link to each other with a lever that the is fixed in bucket top bar of exerting pressure, the other storage cylinder pressure of existing side by side of the cylinder of exerting pressure, exert pressure cylinder import department check valve with the bucket in communicate, the exit check valve links to each other with the import of storage cylinder pressure, the seal that the built-in suction pipe of storage cylinder pressure, suction pipe one end pass the storage cylinder pressure communicates with the outer pipeline that arrives shower nozzle of bucket, and shower nozzle is installed in the top of transfusion hard tube, the other end of this pipe links to each other with the handle of a belt switch, is connected a flexible pipe between this handle and the suction pipe.
