Technical Field

The invention belongs to the field of unmanned aerial vehicles, and particularly relates to an efficient operation agricultural plant protection unmanned aerial vehicle.

Background

Along with the progress and the development of unmanned aerial vehicle technique, replace the manual work to carry out agricultural plant protection work gradually, wherein, the medicine sprays unmanned aerial vehicle and has that the operation height is low, drifts less, can hover in the air, need not special airport of taking off and land, and the downdraft that the rotor produced helps increasing fog and flows the penetrability to the crop, and the prevention and cure effect is high, and remote control operation sprays the operation personnel and has avoided exposing in the danger of pesticide, has improved a great deal of advantages such as spraying operation security.

However, the agricultural quality and protection unmanned aerial vehicle has a small load, the load range is 5-15L, the agricultural quality and protection unmanned aerial vehicle needs to frequently take off and land in the process of spraying pesticides on a large-area farmland, liquid medicines are supplemented into the pesticide box, the operation is time-consuming and labor-consuming, and the working efficiency is not high; on the other hand, due to the influence of different environmental factors such as wind power and terrain in the farm field and the change of the weight of the residual liquid medicine in the medicine box at any time, the flying speed of the unmanned aerial vehicle is difficult to keep consistent all the time in the medicine spraying process, and the problem of uneven pesticide spraying is caused.

Therefore, an efficient operation agricultural plant protection unmanned aerial vehicle is provided to solve the problems.

Disclosure of Invention

The invention aims to provide an efficient operation agricultural plant protection unmanned aerial vehicle which is high in efficiency and capable of uniformly spraying liquid medicine, aiming at the problems of low working efficiency and nonuniform spraying.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an agricultural plant protection unmanned aerial vehicle of high-efficient operation, includes organism and explosive box, the shower nozzle is installed to the bottom of explosive box, the upper end fixed mounting of explosive box has the connecting block, the joint hole that matches with the connecting block is seted up to the lower surface of organism, be equipped with the clamping mechanism who is used for the fixed connection piece in the organism, fixedly connected with level setting's closing plate on the inside wall of explosive box, two first through-holes have been seted up in the closing plate, the upper surface of closing plate rotates and is connected with the rotor plate, two second through-holes that match the setting with first through-hole have been seted up in the rotor plate, the lower extreme of explosive box passes through spring fixedly connected with pterygoid lamina, the upper surface fixedly connected with threaded rod of pterygoid lamina, the lower bottom surface, closing plate and the rotor plate of explosive box, The sealing plate slides in a sealing mode, the threaded rod is sleeved with a threaded cylinder in an external thread mode, and the threaded cylinder is fixedly embedded in the rotating plate.

The invention has the advantages that:

after the pesticide in a explosive box sprayed, can take off the explosive box to it is fixed with another explosive box and organism concatenation of filling with the pesticide fast through joint mechanism, need not frequently to add the pesticide in the explosive box at the course of the work, and convenient quick realizes spraying the operation in succession, has effectively improved work efficiency.

At spraying the in-process, lead to unmanned aerial vehicle flying speed fast and different because of factors such as wind-force, topography and explosive box self weight, when unmanned aerial vehicle's flying speed is slower, the air current velocity of flow who skims over the pterygoid lamina surface is slower, and the pterygoid lamina receives the atmospheric pressure effect less, is not enough to cause the spring to take place deformation, and the contact ratio of coincidence degree of first through-hole and second through-hole this moment is less, and the volume of liquid medicine flow direction shower nozzle is less in the liquid reserve tank.

When unmanned aerial vehicle's flying speed is very fast, the air current velocity of flow that skims over pterygoid lamina surface is very fast, can know according to Bernoulli's principle, when equal altitude flows, the velocity of flow is fast more, then pressure is less, then the pterygoid lamina receives atmospheric pressure's effect great, thereby make pterygoid lamina drive threaded rod rebound, the spring is compressed, the threaded rod drives and rotates with screw-thread fit's screw thread section of thick bamboo, then the rotor plate rotates certain angle, the overlap ratio increase of first through-hole and second through-hole this moment, the liquid medicine increases to the volume of shower nozzle department through first through-hole and second through-hole flow in the liquid reserve tank, when the area that unmanned aerial vehicle skived in unit interval increases, the volume of the liquid medicine that the shower nozzle sprayed also increases.

Preferably, the clamping mechanism includes that two levels set up the dwang in the organism, the one end fixedly connected with L shape joint pole of dwang, L shape joint pole rotates with the fixed connection department of dwang and runs through there is the pivot, the both ends of pivot and the inside wall fixed connection of organism, all be equipped with the draw-in groove on the lateral wall of connecting block both sides, the other end of dwang passes through electric telescopic handle and is connected with the interior top surface of organism, can stabilize, carry out joint or dismantlement to the connecting block fast.

Preferably, sliding connection has the kicking block on the inside wall of explosive box, it is connected with the (mixing) shaft to rotate on the lateral wall of kicking block, install the otter board on the lateral wall of (mixing) shaft, coaxial arrangement has the gear on the (mixing) shaft, the upper end fixedly connected with rack of threaded rod, wheel and rack toothing, unmanned aerial vehicle flying speed is when external factors change, and the pterygoid lamina receives the atmospheric pressure size change, drives the pterygoid lamina and reciprocates to drive the rack from top to bottom, the rack drives the gear revolve of meshing with it, then the otter board is the centre of a circle upset around the (mixing) shaft, stirs the liquid medicine in the explosive box, guarantees that each composition is even and active in the liquid medicine, and the kicking block can drive the (mixing) shaft and float in the liquid level top simultaneously, can take into the liquid.
