As shown in fig. 1-6, when the device of the present invention is in the initial state, the pesticide cavity 14 is filled with pesticide, the magnetic floating block 37 and the closing switch 36 are in the abutting state, the electromagnet 65 is in the non-energized state, the speed regulating spring 67 is in the compressed state, and the driving friction wheel 57 and the pesticide spraying friction wheel 60 are in the abutting state;
sequence of mechanical actions of the whole device:
when the device starts to spray pesticide, the motor 34 is started to drive the motor spline shaft 55 to rotate, the motor spline shaft 55 drives the driving friction wheel 57 to rotate through the switching main shaft 56, so as to drive the pesticide spraying friction wheel 60 to rotate, the pesticide spraying friction wheel 60 drives the speed regulating bevel gear 64 to rotate through the speed regulating bevel gear shaft 61, so as to drive the speed regulating straight gear 62 to rotate, the speed regulating straight gear 62 drives the conical friction wheel 68 to rotate through the conical friction wheel shaft 63, so as to drive the speed regulating friction wheel 69 to rotate, the speed regulating friction wheel 69 drives the water pump spline shaft 33 to rotate through the speed regulating main shaft 71, so as to drive the water pump impeller 20 to rotate, so that pesticide in the pesticide cavity 14 is sucked into the water pump cavity 22 through the pesticide inlet hose 21 at the moment and then is introduced into the mist nozzle 16 through the pesticide outlet hose 15, and finally is sprayed out in a mist form;
when the device is in a flying state, the propeller 23 rotates, namely the propeller shaft 24 rotates, so that the propeller 23 utilizes air to generate downward thrust, the device moves upwards, and the size of air flow generated by the propeller 23 has certain influence on spraying of the atomized pesticide;
the left propeller shaft 24 rotates, so that the propeller belt 27 drives the centrifugal wheel shaft 28 to rotate, so as to drive the centrifugal wheel 43 to rotate, so that the centrifugal block 42 is acted by centrifugal force at the moment, so as to overcome the pulling force of the centrifugal block spring 38 to move outwards, so as to overcome the pushing force of the crank turntable 49 to push the centrifugal push block 41 to move leftwards, so that the speed regulation pull rope 35 is gradually in a relaxed state at the moment, so that the speed regulation slide block 70 correspondingly moves downwards under the pushing force of the speed regulation spring 67, so that the speed regulation friction wheel 69 is driven to move downwards through the speed regulation main shaft 71, so that the position of the abutting joint of the speed regulation friction wheel 69 and the conical friction wheel 68 is changed, the transmission ratio between the speed regulation friction wheel 69 and the conical friction wheel 68 is changed, that when the speed regulation friction wheel 69 moves downwards, the rotating speed of the conical friction wheel 68 is accelerated, so as to, so that the thrust of the pesticide sprayed by the mist nozzle 16 is larger, thereby reducing the influence of the airflow generated by the propeller 23 on the spraying of the mist pesticide;
the rotating speed of the water pump impeller 20 is increased along with the increase of the rotating speed of the propeller 23, namely the spraying strength of the pesticide is increased, so that the spraying strength of the pesticide can be adjusted in real time along with the rotating speed of the propeller 23, and the spraying strength of the pesticide is reduced along with the decrease of the rotating speed of the propeller 23, so that the influence of a reaction force generated by continuous high-strength pesticide spraying on the normal flight of the device is avoided;
when the device needs to be lifted and reversed, pesticide spraying is not needed at the moment, and the rotating speed of the propeller 23 reaches the fastest speed, so that the speed-regulating friction wheel 69 moves downwards to be in a separation state with the conical friction wheel 68 at the moment, the speed-regulating friction wheel 69 stops rotating, the spray nozzle 16 also automatically stops spraying pesticide, and the purpose of saving pesticide is achieved;
along with the consumption of the pesticide in the pesticide cavity 14, the magnetic floating block 37 also descends along with the height of the pesticide liquid level, when the pesticide in the pesticide cavity 14 is used up, the magnetic floating block 37 descends to just contact with the starting switch 13, so that the electromagnet 65 is started at the moment, the repulsion force between the electromagnet 65 and the switching slide block 58 overcomes the thrust of the switching spring 66, and meanwhile, the switching main shaft 56 drives the driving friction wheel 57 to move leftwards to just abut against the pesticide filling friction wheel 59, so that the pesticide spraying friction wheel 60 stops rotating at the moment, namely, the mist nozzle 16 stops spraying the pesticide;
meanwhile, the driving friction wheel 57 drives the pesticide filling friction wheel 59 to rotate, so as to drive the pesticide filling friction wheel shaft 54 to rotate, the pesticide filling friction wheel shaft 54 drives the pinion 51 to rotate through the main gear 53, so as to drive the crank rotating disc shaft 50 to rotate, so as to drive the cylindrical pin 48 to rotate by taking the crank rotating disc shaft 50 as a center, so that the cylindrical pin 48 drives the pesticide filling piston 46 to move up and down in the pesticide filling piston cavity 47 through the piston push rod 45, so that air enters the pesticide filling piston cavity 47 through the pesticide filling pipe 75 and the liquid inlet one-way valve 74 and enters the pesticide cavity 14 through the pesticide filling cavity 72 and the liquid filling one-way valve 73, and the pesticide filling pipe 75 generates a certain suction force;
thereby only need fly the device control in the pesticide jar top of pesticide this moment, and guarantee that fill the pencil 75 and go deep into in the pesticide jar, thereby make the pesticide will inhale to pesticide chamber 14 in through filling the pencil 75, thereby the effect of the supplementary pesticide of going up of device has been realized, the efficiency of spouting the medicine has been improved, and along with the increase of pesticide in pesticide chamber 14, magnetism floater 37 rises with thereupon, thereby when again with close switch 36 butt, thereby electro-magnet 65 closes, thereby spout medicine friction pulley 60 again with initiative friction pulley 57 butt, and initiative friction pulley 57 breaks away from with filling the medicine friction pulley 59, thereby this moment fill medicine piston 46 stop to remove, thereby the pesticide stops, and water pump impeller 20 can continue to rotate, thereby can continue the spraying of pesticide.
The invention has the beneficial effects that: this device passes through the rotational speed of centrifugal wheel real-time supervision screw, but the rotational speed of real-time adjustment water pump in cooperation speed governing chamber simultaneously, thereby will increase the intensity of the pesticide that vaporific nozzle spouts the department through improving the water pump rotational speed when the screw rotational speed is becoming fast, thereby the influence of the air current that the screw produced to vaporific pesticide has been reduced, the normal spraying of pesticide has been guaranteed, and the spraying intensity of pesticide will reduce thereupon when speed reduces, thereby avoided the normal flight of the reaction force influence device that lasting high strength pesticide blowout produced, and exhaust when the pesticide and can fill the medicine piston and remove by automatic start, thereby the effect of supplementary pesticide has been realized, the spraying efficiency of pesticide has been improved.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
