Description
Technical field
The utility model relates to airborne pesticide spraying device technical fields, in particular to a kind of helicopter drag reduction wave resistance
Gush sprinkling medicine-chest.
Background technique
With the maturation of helicopter technology, helicopter pesticide spraying, can not at agriculture application using more and more extensive
Or scarce a part.The important component that helicopter sprinkling be can not ignore is sprinkling medicine-chest, carrying agricultural chemicals liquid in medicine-chest.Due to straight
Aircraft speedup sometimes in operation is risen, slows down sometimes, rises sometimes, decline sometimes, it is huge that this can be such that in medicine-chest liquid generates
Big surge impacts medicine-chest inner wall, keeps the center of gravity of airplane unstable, influences spray effect, or even will affect the safety of aircraft flight.It is existing
Measure used by sprinkling medicine-chest is to add kickboard inside medicine-chest, and the vibration for reducing liquid is splashed, but actual effect is not
Ideal, sprinkling medicine-chest be in kickboard plus the suction structure such as spring, but liquid level changes at any time, is unable to ensure kickboard to liquid
The dynamic compacting of surface wave, and existing sprinkling medicine-chest form construction design is unsatisfactory, plays inhibition to the flight of aircraft,
Cause energy consumption excessive, working efficiency is low.
Utility model content
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot

Windage in few flight course.Partition can also increase the strength and stiffness of cabinet.
Further, the front end of the protruding portion is close to the front end of the cabinet, the partition above the drug slot across
On the cabinet of the drug slot two sides.
In this way, each region separated in cabinet can flow directly to medicine outlet by drug slot, the delay of medical fluid is avoided, is protected
The continuity for demonstrate,proving sprinkling, avoids being emptied for sprinkling system and damages.
Further, the flowing hole includes round flowing hole in the middle part of the partition and is located at the separator edge
Semicircle flowing hole, the two sides up and down of the partition are arranged in the semicircle overcurrent pore size distribution.
In this manner it is ensured that the bottom of partition has flowing hole, can mutually be flowed convenient for the medical fluid in each region of separation
It is logical, avoid the delay of medical fluid.
Further, the width of the box back and the equivalent width for going straight up to motor spindle, and the two sides of its width direction
Gradually extend outwardly from back to front；The front center of the cabinet is recessed backward, keeps the projection of the cabinet vertically whole
It is Y-shaped；Respectively there is one to use observation window made of transparent material for the two sides of the case lid front end.
In this way, the two sides of cabinet are extended outwardly, the capacity of cabinet can be increased, increase drugloading rate.And front end is outside
The two sides of extension can stretch out helicopter bottom section, so that it may be observed by the observation window being arranged on case lid.And cabinet
Front end can also reduce the windage of front end to two sides bifurcated, while can guarantee that medical fluid smoothly flows into the medicine outlet of rear end again.
It further, is arc-shaped at the front edge of the cabinet, and arc radius is greater than 5cm.
In this way, the windage of cabinet front end can be further decreased.
Further, the rear end sides of the case lid are respectively equipped with a balance lid.
In this way, the position of centre of gravity of adjustable sprinkling medicine-chest.
Further, the two sides of the middle and back of the case lid are each provided with the rear cleaning hole an of strip, middle front part
Two sides are each provided with the preceding cleaning hole an of strip, clean hole before described and arrange in splayed configuration.
In this way, convenient clean entire sprinkling medicine-chest.
Further, the side of the cabinet is additionally provided with medicine feeding hole.
In conclusion the utility model have it is reasonable in design, can be effectively reduced the shaking of flight course Chinese medicine liquid,
The advantages that reducing surge, improving flight stability.
