The side body 3-2 is equipped with third feed inlet 3-21, and third feed inlet 3-21 is connected to the second discharge port 6-3;Air hose 3-3 is located at square chest
Inside 3-4;Jet pump 3 further includes with air hose 3-3 transmission connection for adjusting air hose 3-3 and nozzle 3-1 along the phase of injection direction
To the driving device 3-5 of position.Different mixing chamber volumes is set for different medicament conveying capacities, it is ensured that jetting height is maximum
Change.
Working air current undergoes the primary boosting of surge tank 10 before entering jet pump 3, avoids working air current by mixing chamber
When generate disturbance, undergo secondary booster in nozzle 3-1, be ejected medicament under biggish pressure difference, spray distance is farther.
Driving device 3-5 can use Patent No. CN203767624U, middle lead screw in entitled pneumatic conveying jet pump 3
With the structure of lead screw base cooperation, but the structure there are still following disadvantage (1) since lead screw base needs to move together with air hose 3-3
Dynamic, square chest 3-4 needs to open wide completely in the range of lead screw base activity, or one lead screw cover of setting, holds when adjusting the position air hose 3-3
Easily make internal contamination dust, if gas leakage occurs in inside, be easy to accidentally injure staff;(2) since air velocity is larger, air hose
The minimum change in location of 3-3 can generate biggish injection situation and change, and it is micro- to be difficult control air hose 3-3 generation by lead screw base
Thin tail sheep needs to continue adjusting screw seat and sets, while observing injection situation, easily cause fatigue, control especially in debugging
