The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-5 The utility model provides a technical solution: an agricultural drone spraying device, comprising a mixing box 1, a top cover 11 is detachably installed on the top of the mixing box 1 through a thread, a plurality of medicine storage boxes 2 are fixedly installed on the top of the top cover 11, the medicine storage boxes 2 and the top cover 11 are connected through a connecting pipe, and a metering pump 21 is installed in the middle of the connecting pipe, a top guard plate 13 is fixedly installed on the top of the medicine storage box 2, and an adjusting plate 3 is rotatably connected to the top of the top cover 11;

[0023] A passive gear 31 is integrally formed on the top of the adjusting plate 3, a magnetic suction nozzle 32 is connected through the circumference of the adjusting plate 3, a stirring blade 4 is arranged in the inner cavity of the mixing box 1, a stirring motor is fixedly installed on the top of the passive gear 31, and the output end of the stirring motor is fixedly connected to the top of the stirring shaft of the stirring blade 4, an adjusting motor 51 is fixedly installed on one side of the bottom of the top guard plate 13, and a driving gear 5 is fixedly connected to the output end of the adjusting motor 51, and a filter liner 6 is fixedly installed on the bottom of the top cover 11;

[0024] One group of medicine storage boxes 2 is filled with an equal amount of diluted clean water. After the medicine storage boxes 2 are filled with the medicines to be dispensed, when the medicines need to be dispensed, the metering pump 21 on the external connecting pipe of the medicine storage box 2 can quantitatively introduce the medicines in the medicine storage box 2 into the mixing box 1, so that multiple medicines can be mixed with the diluted clean water to form the medicine to be sprayed. The metering pump 21 and the servo adjustment motor 51 are electrically connected to a controller;

[0025] The output end of the servo adjustment motor 51 drives the active gear 5 to transmit the passive gear 31 to periodically rotate a unit angle, so that the adjustment plate 3 rotates periodically inside the top cover 11, so that the magnetic suction nozzles 32 on the circumference of the adjustment plate 3 can be connected with multiple groups of circumferentially arranged medicine storage boxes 2 connecting pipes respectively, so that with the cooperation of the metering pump 21, the medicines in the multiple groups of medicine storage boxes 2 can be introduced into the mixing box 1 in batches, and with the cooperation of the stirring motor and the stirring blade 4, the medicines and the diluted clean water can be stirred and mixed evenly, so that automatic matching of multiple medicines is realized for metered dispensing. After the spraying of the medicine in the drone mixing box 1 is completed, a short pause can be made and the medicine can be automatically dispensed, the operation is more automated, and the work efficiency is improved.

[0026] Among them, the stirring blade 4 is located in the inner cavity of the filter liner 6, and a liquid outlet pipe 12 is connected to the outside of the mixing box 1. The liquid outlet pipe 12 is used to discharge the mixed medicine inside the mixing box 1. The stirring blade 4 can stir and mix the medicine introduced into the filter liner 6 with the diluted clean water to be uniform. The mixed medicine can overflow from the filter liner 6, be discharged through the liquid outlet pipe 12, and be sprayed on the crops through the atomizer on the drone.

The adjustment plate 3 is a ring structure. The outer edge of the active gear 5 is meshed with the outer edge of the passive gear 31. The output end of the servo adjustment motor 51 drives the active gear 5 to drive the passive gear 31 to periodically rotate a unit angle, so that the adjustment plate 3 rotates periodically inside the top cover 11. In this way, the magnetic suction nozzle 32 on the circumference of the adjustment plate 3 can be connected with the multiple groups of circumferentially arranged connecting pipes of the medicine storage boxes 2 respectively. In this way, with the cooperation of the metering pump 21, the medicines in the multiple groups of medicine storage boxes 2 can be introduced into the mixing box 1 in batches.

[0028] Working principle: When in use, first fill one group of medicine storage boxes 2 with an equal amount of diluted clean water, and then fill the medicine storage boxes 2 with the medicines to be dispensed. When the medicines need to be dispensed, the metering pump 21 on the external connecting pipe of the medicine storage box 2 can quantitatively introduce the medicines in the medicine storage box 2 into the mixing box 1, so that multiple medicines can be mixed with diluted clean water to form the medicine to be sprayed;

[0029] Then, when the drone is automatically dispensing medicine, the output end of the servo adjustment motor 51 drives the active gear 5 to drive the passive gear 31 to periodically rotate a unit angle, so that the adjustment plate 3 rotates periodically inside the top cover 11, so that the magnetic suction nozzles 32 on the circumference of the adjustment plate 3 can be connected with multiple groups of circumferentially arranged medicine storage boxes 2 connecting pipes respectively, so that with the cooperation of the metering pump 21, the medicines in the multiple groups of medicine storage boxes 2 can be introduced into the mixing box 1 in batches, and with the cooperation of the stirring motor and the stirring blade 4, the medicines can be stirred and mixed evenly with the diluted clean water, so that the automatic matching of multiple medicines for metered dispensing is realized. After the spraying of the medicine in the mixing box 1 of the drone is completed, it can be automatically dispensed after a short pause, and the operation is more automated, which improves work efficiency.
