Abstract
The utility model relates to a spraying instrument drug adding device. The drug adding device comprises a graduated cylinder; a piston with a piston rod is positioned in the graduated cylinder; a liquid outlet tube with a liquid outlet valve and a liquid inlet tube with a liquid inlet valve are connected at one end of the graduated cylinder. By adopting the structure of the graduated cylinder plus the piston, and by using the piston to draw off medical liquor, the metering is accurate, the medical liquor is not easy to sprinkle, the pollution of the medical liquor to the environment and human body is avoided, and the utility model is in particular suitable for being used for an agricultural sprayer.
Description
Technical field
The utility model relates to a kind of device of adding soup for agricultural atomizer or spraying machine.
Background technology
Agricultural chemicals is a kind of poisonous product, and its use amount should strict control.At present when giving the sprayer dosing, use the measurer of container and so on of band width value.This measurer is simple in structure, but uses inconvenience, and soup is unrestrained easily, contaminated environment and operator's skin.
Summary of the invention
The purpose of this utility model is that a kind of spraying apparatus doser will be provided, and this spraying apparatus doser is easy to use, and soup is difficult for unrestrained.
The purpose of this utility model is achieved in that this doser comprises graduated cylinder, and the piston of band piston rod is arranged in the graduated cylinder, and an end of graduated cylinder is connected with the drain pipe of drag-out valve and brings the feed tube of liquid valve into.
Described feed tube is connected with screw cap, is connected with breather valve on the screw cap.
Described graduated cylinder is that the right angle is connected with feed tube.
The utility model adopts graduated cylinder to add structure of piston, utilizes piston to extract soup, accurate measurement, and soup is difficult for unrestrained, has avoided the pollution of soup to environment and human body, is particularly suitable for agricultural atomizer and uses.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Description of drawings
Fig. 1 is the structure chart of a specific embodiment of the present utility model.
Fig. 2 is the structure chart of another specific embodiment of the present utility model.
Fig. 3 is the structure chart of another specific embodiment of the present utility model.
1. drain pipes among the figure, 2. liquid valve, 3. piston rod, 4. blow vent, 5. graduated cylinder, 6. piston, 7. feed liquor valve, 8. breather valve, 9. screw cap, 10. feed tube, 11. soup bottles.
The specific embodiment
In Fig. 1, this doser comprises graduated cylinder 5, and graduated cylinder 5 adopts transparent material to make, and indicates scale value above.The piston 6 that band piston rod 3 is arranged in the graduated cylinder 5, the lower end of graduated cylinder 5 are connected with the drain pipe 1 of drag-out valve 2 and bring the feed tube 10 of liquid valve 7 into.
During use, feed tube 10 is inserted in the soup bottle 11, pulling piston rod 3 forms negative pressure, and feed liquor valve 7 is opened, and liquid valve 2 is closed, and soup is inhaled in the graduated cylinder 5.Piston rod 3 is pushed ahead, owing to be subjected to the pressure of soup, feed liquor valve 7 cuts out, and liquid valve 2 is opened, and soup is extruded in graduated cylinder 5, enters in the sprayer through drain pipe 1.By observing the scale value on the graduated cylinder 5, can control the amount of liquid medicine that sucks or extrude.
In Fig. 2, this doser comprises graduated cylinder 5, and the piston 6 of band piston rod 3 is arranged in the graduated cylinder 5, and the lower end of graduated cylinder 5 is connected with the drain pipe 1 of drag-out valve 2 and brings the feed tube 10 of liquid valve 7 into.Feed tube 10 is connected with screw cap 9, is connected with breather valve on the screw cap 9, and screw cap 9 is used to connect soup bottle 11.
During use, screw cap 9 and soup bottle 11 are tightened, opened breather valve 8, can carry out above-mentioned use operation.
In Fig. 3, this doser comprises graduated cylinder 5, and the piston 6 of band piston rod 3 is arranged in the graduated cylinder 5, and the left end of graduated cylinder 5 is connected with the drain pipe 1 of drag-out valve 2 and brings the feed tube 10 of liquid valve 7 into, and graduated cylinder 5 meets at right angles with feed tube 10 and is connected, and is orthogonal.Feed tube 10 is connected with screw cap 9, is connected with breather valve on the screw cap 9, and screw cap 9 is used to connect soup bottle 11.
The embodiment of Fig. 1 and Fig. 2 is a vertical type, and the embodiment of Fig. 3 is a horizontal.
