Abstract

An efficient knapsack hand sprayer is characterized in that: two piston barrels in a mixed fluid barrel are communicated with the mixed fluid barrel, two connecting rods are arranged in a control mechanism, one end of each connecting rod is respectively connected with two piston rods arranged on the top of the mixed fluid barrel, the other end of each connecting rod arranged on the lower outside part of the mixed fluid barrel is respectively connected with both ends of a lever, at the same time, the middle part of the lever is connected with the mixed fluid barrel, and one control handle is further connected with one end of the lever. According to the utility model, when the lever moves up and down through the control handle, two pistons can be driven to move up and down alternately, thereby continuously conveying drug fluid to the same fluid storage pressure jar. Thus, the utility model not only has small size but also has high lifting speed, flexible operation and good atomization effect, thereby being a convenient and efficient knapsack hand sprayer.

Description

Efficient knapsack hand sprayer

Technical field

The utility model relates to a kind of agricultural sprayer unit, particularly a kind of efficient knapsack hand sprayer.

Background technology

Usually the farmland employed sprayer of spraying insecticide is still employing mostly mainly by the dosing tube, be positioned at the liquid storage pressure bottle of dosing tube one side and be arranged on the knapsack hand sprayer that the dosing tube is used for carrying to the liquid storage pressure bottle formations such as piston type transfusion mechanism of soup, because above-mentioned sprayer is the transfusion mechanism that is made of sprayer the piston in a piston cylinder and the piston cylinder, so in the course of work, transfusion mechanism force feed soup in the liquid storage pressure bottle discontinuously only when moving by the rocking bar driven plunger, not only amount of infusion is little to make it, boost in pressure speed curtain, and, atomizing effect is poor during spray liquid, spray rate is slow, labour intensity is also bigger, it is CN2122484 that a kind of notification number was once arranged, name is called the patent application of " double-piston backpack anti-seep water hand sprayer ", it is to increase a piston mechanism and liquid storage pressure bottle on the basis of said structure, and in the operating mechanism of driven plunger action, the two ends that are positioned at the drive link on dosing tube top are connected with the two-piston bar that places dosing tube top respectively, lever one end that vertically is arranged on dosing tube one side is connected with the drive link middle part, the other end places the dosing tube bottom to be connected with crank, though it can increase the conveying capacity of soup effectively, but since the driven plunger action time be by the lever in the operating mechanism make its synchronously on, following action, discontinuously soup is sent to respectively in the corresponding liquid storage pressure bottle, not only comparatively require great effort when making its operation, and spray effect is still undesirable, simultaneously, this sprayer volume is also bigger.

The utility model content

The utility model is at the deficiency that exists in the background technology, and a kind of simple in structure, operation is light, atomizing effect is good efficient knapsack hand sprayer is provided.

Its concrete solution is: place the two-piston tube bottom of the transfusion mechanism in the dosing tube to be connected with a liquid storage pressure bottle, and, be provided with check (non-return) valve between two-piston tube and this liquid storage pressure bottle.The two connecting rod one ends that are provided with in the operating mechanism flexibly connect with the two-piston bar that places dosing tube top respectively, and the other end that places dosing tube outer lower portion is movably connected in the two ends of lever respectively, simultaneously, the middle part of lever is movably connected on the dosing tube fulcrum as lever, and control crank is connected an end of this lever.

The utility model is during by the upper and lower rocking lever of control crank, can drive two-piston simultaneously and replace upper and lower action, incessantly with the soup force feed to the same liquid storage pressure bottle, not only volume is little to make it, and boost in pressure speed is fast, operation is light, atomizing effect good, and its reality is a kind of convenience, knapsack hand sprayer efficiently.

Fig. 2 is A-A cutaway view of Fig. 1.

Fig. 3 is a structure vertical view of the present utility model.

The specific embodiment

Fig. 1, Fig. 2, among Fig. 3, place the two-piston tube 11 in the dosing tube, 12 are connected on the dosing tube 2 by a sealing nut gland 10 respectively, the soup delivery outlet that the bottom of two-piston tube is provided with is through interior threeway 16, outer threeway 3 is communicated with the liquid storage pressure bottle 1 that is arranged on the dosing tube outside, and, 16 of two-piston tube soup delivery outlet and interior threeways, 3 of interior threeway 16 and outer threeways are respectively arranged with and only send valve 13,14,4, and the inlet place of two-piston tube bottom is provided with check (non-return) valve 15, the two-piston bar 8 that connects piston in the operating mechanism respectively with connecting rod 7, an end of 9 flexibly connects, place the other end of dosing tube outer lower portion to be connected to the two ends of lever 17, and the middle part movable supporting of lever 17 is on the support member on the dosing tube 5, simultaneously, control crank 6 is connected with an end of lever 17.

During use, when by the upper and lower action of lever actuated connecting rod, can drive two-piston respectively and alternately produce the force feed effect, be sent to soup in the liquid storage pressure bottle continuously, fast, and by the injection equipment spray liquid that is connected with outer threeway 3, thereby realize more convenient result of use efficiently with shower nozzle.

Claims (1)

1, a kind of efficient knapsack hand sprayer, mainly by dosing tube (2), liquid storage pressure bottle (1), being positioned at the dosing tube is used for carrying the piston type transfusion mechanism and the operating mechanism of soup to constitute to the liquid storage pressure bottle, two-piston tube (11) in the mechanism is characterized in that infusing, (12) bottom is communicated with liquid storage pressure bottle (1), and be provided with check (non-return) valve between piston cylinder and liquid storage pressure bottle (1), two connecting rods (7) that are provided with in the operating mechanism, (9) the one end flexibly connects with the two-piston bar (8) that places dosing tube (2) top respectively, and the other end that places dosing tube outer lower portion is movably connected in the two ends of lever (17) respectively, simultaneously, the middle part movable supporting of lever is on the dosing tube, and control crank (6) is connected an end of this lever.
