Referring to fig. 5, spherical grooves are drilled at the left and right ends of the toggle plate 11, balls 1101 are rotatably connected in the spherical grooves, the outer ends of the balls 1101 are slidably connected with the inner wall of the fixed cylinder 9, and the arrangement of the balls 1101 makes the toggle plate 11 move more smoothly in the fixed cylinder 9, thereby reducing friction influence.

Referring to fig. 6, the ends of the magnetic ball 22 and the magnet piece 24 adjacent to each other are disposed in opposite directions, and an attractive force is generated by the opposite directions between the ends of the magnetic ball 22 and the magnet piece 24 adjacent to each other, so that the magnetic ball 22 attracts the magnet piece 24 to move closer to the magnet piece, and the adiabatic powder is made of an Fe-Ni alloy material, has an Ni content of 80%, and can shield magnetism of the magnetic ball 22 in a dense state by using the adiabatic powder made of the Fe-Ni alloy material.

In the invention, when a technician in the relevant field uses the device, firstly the sealing plug 4 is opened, fertilizer and aqueous solution are added into the liquid storage ball 2 and mixed, then the sealing plug 4 is covered, then the unmanned aerial vehicle body flying 1 is started, in the flying process of the unmanned aerial vehicle body 1, the resistance movable block 8 pushes the air in the inclined tube 5 to enter the telescopic air bag 10 under the resistance extrusion action, so that the piston 6 is pushed to extrude the air in the inclined tube 5 to expand and extend, the poking plate 11 and the thick rod 12 are driven to move downwards, the thick rod 12 moves downwards to drive the poking blade 13 to swing under the action of the elastic membrane 16, so that the fertilizer and the aqueous solution are fully mixed, meanwhile, the telescopic spring 14 is compressed, the resistance movable block 8 is influenced by the flying and is changed, and therefore, under the elastic resetting action of the telescopic spring 14, when the resistance is greater than the elastic force, the thick rod 12 moves downwards, when the resistance is smaller than the elastic force, the thick rod 12 moves upwards, so that the thick rod 12 continuously moves up and down to drive the stirring blade 13 to swing back and forth, so as to promote the sufficient mixing of the fertilizer and the water solution, improve the utilization rate of the fertilizer, then the water pump 19 is started to enable the thick rod 12 to extract the fertilizer liquid in the liquid storage ball 2 through the liquid outlet pipe 17 and to be sprayed out through the elastic hose 20, meanwhile, the thick rod 12 also drives the telescopic airbag 10 to change in a telescopic manner when moving up and down, so as to realize the reciprocating motion of the extrusion piston 6, when the piston 6 moves upwards, the air on the upper side of the piston is extruded, at the moment, the rubber sealing piece 25 is pushed open, the air is blown into the air guide pipe 23 and enters the elastic magnetism insulation bag body 21 through the air permeable film 26 to deform and expand, so as to enable the magnetism insulation powder to be dispersed, the magnetic shielding of the magnetic ball 22 is cancelled, and the magnet piece 24 is close to the magnetic ball 22 under the attraction of the magnetic ball 22 to drive the elastic hose 20 to move upwards, and when piston 6 downstream, extrude its downside air, extract the air of upside, make elasticity magnetic isolation utricule 21 reconversion, magnetic ball 22 is shielded by the magnetism, and elastic hose 20 resets to the realization drives elastic hose 20 and carries out the up-and-down motion, makes spraying of fertilizer liquid more even, reinforcing fertilization effect.

The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
