Detailed Description
According to the utility model discloses a design combines the figure to provide a middle-size and small-size plant protection unmanned aerial vehicle here with preventing the embodiment of the big change pesticide box in focus position. Referring to fig. 1 to 4, the pesticide box 100 includes a housing 200, a capsule 300 and an elastic member 400. Wherein the housing 200 may be mounted to a suitable location on the plant protection drone to meet the requirements of the overall structural design; the medicine bag 300 is installed inside the housing 200 for containing the liquid medicine, and the elastic member 400 is compressed between the medicine bag 300 and the housing 200 for compressing the medicine bag 300 to ensure that the empty space inside the medicine bag 300 is maintained within a small range, thereby preventing the liquid medicine from oscillating inside the medicine bag 300.
Specifically, the whole closed structure of shell 200 is equipped with an openable case lid 210 at the top of shell 200, but articulated also the lock joint between case lid 210 and the shell 200, can take out anther sac 300 through opening case lid 210, still seted up an observation hole 230 on case lid 210 simultaneously, be convenient for look over the compression state of inside anther sac 300 through observation hole 230, still seted up a through-hole 220 in the bottom of shell 200 one side, this through-hole 220 is used for stretching out anther sac 300's liquid outlet 360.
Optionally, housing 200 is injection molded.
In addition, the medicine bag 300 comprises a top plate 310, a side wall 320 and a bottom plate 350, wherein the top plate 310 and the bottom plate 350 are made of hard paper, the side wall 320 is made of flexible film, the top plate 310, the bottom plate 350 and the side wall 320 can be connected by hot melting, in order to ensure that the medicine bag 300 is not twisted when being compressed, a large retaining ring 330 and a small retaining ring 340 are arranged on the side wall 320 at intervals, the large retaining ring 330 and the small retaining ring 340 are both bonded with the side wall 320, and the shapes of the large retaining ring 330 and the small retaining ring 340 are both matched with the cross section shape of the side wall 320; the top plate 310 is provided with a one-way vent valve 370 made of a polymer film, the one-way vent valve 370 has the characteristics of water and gas isolation, the bottom of the side wall 320 is provided with a liquid outlet 360, and the liquid outlet 360 is also provided with a liquid outlet valve.
