Abstract

The utility model discloses a plant protection unmanned aerial vehicle prevents shaking medical kit, including box and case lid, still including preventing shaking the mechanism, prevent shaking the mechanism and include vertical setting guide rail on the box medial surface, with guide rail about sliding fit's clamp plate, fix the buoyancy piece on the clamp plate bottom surface and set up on the clamp plate top surface and with the friction pack of guide rail one-to-one. The utility model discloses plant protection unmanned aerial vehicle prevents shaking medical kit, its clamp plate floats on the liquid medicine liquid level under buoyancy piece and frictional resistance effect, the clearance between clamp plate and the liquid medicine liquid level is very little or the clearance is zero, at unmanned aerial vehicle flight in-process like this, when because of flight gesture, when the hard gas liquid medicine of changes such as speed rocks, liquid medicine liquid level direct action is on the clamp plate, and the impact force that the liquid medicine acted on the clamp plate can be offset to the gravity of clamp plate and the frictional force between spring leaf and the guide rail, thereby play good anti-rocking effect, the elimination liquid level that can be fine rocks the problem that causes unmanned aerial vehicle flight unstability.

Description

Plant protection unmanned aerial vehicle prevents shaking medical kit

Technical Field

The utility model relates to an unmanned air vehicle technique field, in particular to plant protection unmanned aerial vehicle's medical kit.

Background

Plant protection unmanned aerial vehicle flies the accuse through ground remote control or navigation, realizes spraying the operation, can spray medicament, seed, powder etc..

But plant protection unmanned aerial vehicle among the prior art, its medical kit does not prevent the structure that the liquid medicine rocked, at unmanned aerial vehicle diversion, acceleration and deceleration etc. flight in-process, the liquid medicine can produce and rock, and rocks and can influence unmanned aerial vehicle flight stability, and the weight risk occasionally is serious.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a plant protection unmanned aerial vehicle prevents shaking medical kit to solve current plant protection unmanned aerial vehicle medical kit and can not prevent the technical problem that the liquid medicine rocked.

The utility model discloses plant protection unmanned aerial vehicle prevents shaking medical kit, including box and case lid, still including preventing shaking the mechanism, prevent shaking the mechanism and include vertical setting guide rail on the box medial surface, with guide rail about sliding fit's clamp plate, fix the buoyancy piece on the clamp plate bottom surface and set up on the clamp plate top surface and with the friction pack of guide rail one-to-one, the clearance between the limit portion of clamp plate and the box medial surface is less than 1mm, friction pack is including fixing on the bottom plate top surface and being located the spring leaf of guide rail both sides and the bolt of connecting the spring leaf of guide rail both sides, the spring leaf pushes down on the side of guide rail under the bolt pulling force, the gravity of clamp plate is greater than the buoyancy balance that the part of frictional resistance produced by the buoyancy piece between spring leaf and the guide.

Further, the buoyancy block is a foam block.

Further, a handle is arranged on the top surface of the pressing plate.

Further, the case lid passes through the bolt fastening on the box, and is provided with the sealing washer between case lid and the box.

The utility model has the advantages that:

the utility model discloses plant protection unmanned aerial vehicle prevents shaking medical kit, its clamp plate floats on the liquid medicine liquid level under buoyancy piece and frictional resistance effect, the clearance between clamp plate and the liquid medicine liquid level is very little or the clearance is zero, at unmanned aerial vehicle flight in-process like this, when because of flight gesture, when the hard gas liquid medicine of changes such as speed rocks, liquid medicine liquid level direct action is on the clamp plate, and the impact force that the liquid medicine acted on the clamp plate can be offset to the gravity of clamp plate and the frictional force between spring leaf and the guide rail, thereby play good anti-rocking effect, the elimination liquid level that can be fine rocks the problem that causes unmanned aerial vehicle flight unstability.

Detailed Description

The invention is further described with reference to the following figures and examples.

This embodiment plant protection unmanned aerial vehicle prevents shaking medical kit, including box 1 and case lid 2, the bottom of box is provided with row medicine mouth 3, arranges the medicine mouth be used for with the access connection of pump, when spraying insecticide, the pump sends into high pressure nozzle with the liquid medicine from the medical kit pump. This embodiment plant protection unmanned aerial vehicle prevents shaking medical kit still includes prevents shaking the mechanism, prevent shaking the mechanism and include vertical setting guide rail 4 on the box medial surface, with guide rail about sliding fit's clamp plate 5, fix buoyancy piece 6 on the clamp plate bottom surface and set up on the clamp plate top surface and with the friction pack of guide rail one-to-one. The clearance between the limit portion of clamp plate and the box medial surface is less than 1mm, because the clearance between the limit portion of clamp plate and the box medial surface is little for only few partial liquid medicine can follow clamp plate limit portion upward flow when the liquid medicine rocks.

The friction assembly comprises spring pieces 7 which are fixed on the top surface of the bottom plate and located on two sides of the guide rail and bolts 8 which are connected with the spring pieces on the two sides of the guide rail, the spring pieces are pressed on the side surfaces of the guide rail under the pulling force of the bolts, and the part of the pressure plate, with the gravity larger than the friction resistance between the spring pieces and the guide rail, is balanced by buoyancy generated by the buoyancy block. The friction subassembly can adjust the distance between two spring leafs through the bolt in this embodiment, and then reaches the purpose of adjusting the frictional force between spring leaf and the guide rail to adjustable frictional force is preventing that the liquid medicine from shaking the effect that plays.

In this embodiment, the buoyancy block 6 is a foam block; although the buoyancy block may take other forms in different embodiments.

As an improvement to the above embodiment, a handle 9 is arranged on the top surface of the pressing plate, so that the pressing plate can be taken out conveniently through the handle, and the medicine box can be cleaned conveniently.

As an improvement to the above embodiment, the case cover is fixed on the case body through bolts 10, and a sealing ring is arranged between the case cover and the case body, so that the case cover is fixed reliably and is convenient to disassemble and assemble.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
