Abstract

The utility model relates to a portable manpower sprayer for the agriculture. The utility model is widely used for spraying physic liquors to kill pests for crops, and can also be used for spraying water on trees and flowers, and spraying physic liquors. The utility model uses a clamp type pedal which is sheathed below the foot of a person to clamp a middle air bag. In the process of walking for the person, the foot pedals the clamp type pedal, the dead weight of the person applies the force to the air bag, and the physic liquor is sprayed out from a spray head continually with the walking paces. Compared that the force is applied by hand, the utility model has the advantage of labor saving. Under the condition of no cost increase, the labor intensity is improved. Because the hand which is used for applying the force to a pressurizing valve is idle, the hand can hold two spray heads to spray the physic liquor, and therefore, the work efficiency is improved two times.

Description

Pedal type sprayer

The utility model relates to agricultural and goes up a kind of portable type hand sprayer that uses, and it is widely used in sprays the soup eliminating pest to crops, also is used for trees, flowers and plants water spray or spraying liquid.

As everyone knows, agricultural aircraft, pesticide spray truck have begun to be used for agricultural at present, it is still the most general that but the portable type hand pressure sprayer is used, this is because it has following advantage: 1, use the area extensively, no matter be flat-bottomed land, mountain area, still to crops behind the house before the room, the trees flowers and plants in street and park all are suitable for.2, easy to operate, the sprayer back of the body of band soup on the other hand to the plunger pressurizer application of force, is being lifted the shower nozzle spraying liquid after one's death on the other hand.3, expense is low modest, and this spray structure is simple, and cost is low, only consumes soup during use.But weak point is arranged still: for carrying spray tank, proficiency on the body ceaselessly to the pressurizer application of force, lifting the shower nozzle spraying liquid on the other hand, labour intensity is too big.

In view of this, the purpose of this utility model provides a kind of foot-operated sprayer, and the paces that utilize business concern operating a porters' service to walk eject the spray tank inner liquid medicine.

The purpose of this utility model is achieved in that it comprises spray tank, soup valve, check valve, deposits and press jar, shower nozzle valve and shower nozzle; Below people's sole, be provided with the folder formula pedal of an end of upper and lower pedal, and between another cantilever end between the upper and lower pedal of point type pedal, be provided with the air bag of putting band air bag flexible pipe with the spring connection.

Owing to adopt such scheme, not only can reduce labour intensity, and have reliable both hands to hold the shower nozzle spraying liquid, increase work efficiency.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic diagram of the utility model embodiment.

Among the figure: 1 spray tank, 2 soup valves, 3 check valves, 4 deposit the pressure jar, 5 shower nozzle valves, 6 shower nozzles, 7 folder formula pedals, 71 upper footboards, 72 times pedals, 73 springs, 8 air bags, 81 air bag flexible pipes.

Folder formula pedal 7 is by an end of upper and lower pedal 71,72, connects with spring 73, and the other end to be cantilever constitute whippy clip.Cantilever end at upper footboard is provided with through hole.

Air bag 8 is rubber bag of inflation, connects in the air bag upper end.An air bag flexible pipe 81 has an elasticity valve in the connection, air bag is not during pressurized, valve is closed, and valve is opened during pressurized, and air bag 8 places between upper and lower pedal 71,72 cantilever ends of folder formula pedal 7, air bag flexible pipe 81 passes the through hole of upper footboard 71, connect a check valve 3 in the middle of air bag flexible pipe 81, when air bag 8 was not subjected to external force, check valve 3 was closed, and air bag 8 is when being subjected to external force, and air-flow is opened check valve 3; The upper end of air bag flexible pipe 81 connects one and keeps the air of certain pressure to deposit pressure jar 4, connect spray tank 1 bottom (in be furnished with the plunger pressurizer) at air bag flexible pipe 81 sidewalls below the check valve 3 through a conduit, in this conduit, also be equipped with by spray tank 1 inner liquid medicine gravity pressure, the automatic soup valve of opening 2, air bag flexible pipe 81 sidewalls above check valve 3 connect two conduits again, every conduit be linked in sequence nozzle switch 5 and shower nozzle 6.

It is as follows to be described in detail an embodiment course of action of the present utility model with reference to Fig. 1:

Foot-operated sprayer based on spray tank (1) weight of filling soup, the back of the body is after carrying on the body, open point type pedal (7) folder mouth, clamp air bag (8), then folder formula pedal (7) is fastened at a leg instep, two hands are being held two shower nozzles (6) respectively, along with people's walking, riding folder formula pedal (7) step by step, rely on rubber pneumatic bag (8) application of force of people's deadweight to inflation, at this moment, turn on liquid valve (2) by the soup of the interior liquid deadweight of spray tank (1) through 2 outflows of soup valve, depress in adding of air bag (8), air-flow makes soup upwards by check valve (3), pour to deposit and press jar (4), the shower nozzle valve (5) of opening has been located in the reflecting surface ejection, from shower nozzle (6) ejection soup, along with the generation in step of people's walking, pressurization is rhythmically deposited and is pressed jar (4) to keep certain pressure, shower nozzle constantly sprays vaporific soup.

Claims

A kind of foot-operated sprayer comprises: spray tank, soup valve, check valve, deposit press jar, shower nozzle valve shower nozzle, it is characterized in that: fasten at instep and also be provided with the folder formula pedal of an end of upper and lower end pedal underfoot, the air bag of band air bag flexible pipe is set between the upper and lower pedal of folder formula pedal with the spring connection.
