[0015] The beneficial effects of the present invention are as follows: the present invention is a plant protection drone that can quickly replenish liquid and automatically replenish medicine, thereby avoiding waste of liquid medicine and pollution of the environment; the specific implementation method is as follows:

[0016] The operator first removes the top cover, pulls out the rectangular slot frame along the guide of the mounting rail, puts the required medicine into the hopper in the rectangular slot frame, slides the sliding rack to the top close to the toggle rod, then stands up the toggle rod to keep it vertical, and then places the top cover on the outer box so that the buckle on the toggle rod buckles with the auxiliary buckle rod on the sliding rack to complete the preliminary operation;

[0017] Continue to remove the sealed water inlet on the top cover, then pour water into the water tank, buckle the sealed water inlet to seal the water tank, and then rotate the paddle to drive the raised spray system to move along the wave groove in the sliding block, further drive the sliding block to slide back and forth in the rotating circle, and in the process of the sliding block sliding away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, and further drives the air in the outer box to flow through the gap of the sealing funnel into the space between the sealing funnel and the sliding plate. In the process of the sliding plate approaching the sealing funnel, the air is squeezed and first expands the sealing funnel to abut against the connecting tube to seal the outer box. When the rotating circle is stationary, it is also in a sealed state, and the gap is created by pushing the movable baffle away from the fixed plate to flow out to the space between the rotating circle and the sliding block, completing the exhaust;

[0018] During the exhaust process, the pressure inside the outer box decreases, causing the lifting plate to move closer to the top cover in order to balance the pressure. In the process of approaching the top cover, the toggle rod pushes the sliding rack to slide, driving the sliding rack to mesh with the rotating gear on the rotating column, so that the hopper drops the medicine under the outer box. At the same time, due to the movement of the lifting plate, the liquid above also falls under the outer box. After the two are mixed, the work can begin.

[0019] During operation, the main body of the drone drives the outer box to move while driving the pump body on the spraying system to discharge the liquid medicine in the outer box to the nozzle through the water intake pipe to complete the spraying. At the same time, due to the consumption of the liquid medicine, the lifting plate continues to move in order to further balance the pressure, and continues to drive the sliding guide rail to slide, thereby realizing the process of automatic replenishment of medicine and liquid during the spraying process. After the spraying is stopped, no more liquid replenishment is required, and the remaining amount of liquid medicine is small, which is convenient for handling.

[0020] In order to speed up the replenishment of medicine and fluid, there is no need to shut down the drone body. After the liquid in the outer box mounted on the drone body has drained out, the drone body can be lowered so that the outer box contacts the bottom surface, driving the buckle plate to rise, and then the bending rod is rotated along the rotating connecting rod on the connecting bracket to disengage the buckle plate from the outer box. After that, the drone body is moved to the top of the new outer box that has been loaded, and the above operation is repeated in reverse to achieve the replacement of the outer box and realize rapid replenishment of fluid and medicine.

[0021] The device has a simple structure and realizes automatic replenishment of medicine and liquid by using liquid medicine to achieve negative pressure on the box. At the same time, different outer boxes can be quickly replaced. It has good stability and practicality, which is beneficial to the promotion and use of the equipment.

[0040] In practice, the rotating paddles drive the raised spray system to move along the wave groove in the sliding block, further driving the sliding block to slide back and forth in the rotating circle. In the process of the sliding block sliding away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, further driving the air in the outer box to flow through the gap in the sealing funnel into the space between the sealing funnel and the sliding plate. In the process of the sliding plate approaching the sealing funnel, the air is squeezed and first expands the sealing funnel to abut against the connecting tube to seal the outer box. When the rotating circle is stationary, it is also in a sealed state, and the movable baffle is pushed away from the fixed plate to create a gap to flow out to between the rotating circle and the sliding block to complete the exhaust.

[0041] Working principle of the present invention:

[0042] In the initial state, the operator first removes the top cover, pulls out the rectangular slot frame along the guide of the mounting rail, puts the required medicine into the hopper in the rectangular slot frame, slides the sliding rack to the top close to the toggle rod, then stands up the toggle rod to keep it vertical, and then places the top cover on the outer box, so that the buckle on the toggle rod buckles with the auxiliary buckle rod on the sliding rack to complete the initial operation;

[0043] Continue to remove the sealed water inlet on the top cover, then pour water into the water tank, buckle the sealed water inlet to seal the water tank, and then rotate the paddle to drive the raised spray system to move along the wave groove in the sliding block, further drive the sliding block to slide back and forth in the rotating circle, and in the process of the sliding block sliding away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, and further drives the air in the outer box to flow through the gap of the sealing funnel into the space between the sealing funnel and the sliding plate. In the process of the sliding plate approaching the sealing funnel, the air is squeezed and first expands the sealing funnel to abut against the connecting tube to seal the outer box. When the rotating circle is stationary, it is also in a sealed state, and the gap is created by pushing the movable baffle away from the fixed plate to flow out to the space between the rotating circle and the sliding block, completing the exhaust;

[0044] During the exhaust process, the pressure inside the outer box decreases, causing the lifting plate to move closer to the top cover in order to balance the pressure. In the process of approaching the top cover, the toggle rod pushes the sliding rack to slide, driving the sliding rack to mesh with the rotating gear on the rotating column, so that the hopper drops the medicine under the outer box. At the same time, due to the movement of the lifting plate, the liquid above also falls under the outer box. After the two are mixed, the work can begin.

[0045] During operation, the main body of the drone drives the outer box to move while driving the pump body on the spraying system to discharge the liquid medicine in the outer box to the nozzle through the water intake pipe to complete the spraying. At the same time, due to the consumption of the liquid medicine, the lifting plate continues to move in order to further balance the pressure, and continues to drive the sliding guide rail to slide, thereby realizing the process of automatic replenishment of medicine and liquid during the spraying process. After the spraying is stopped, no more liquid replenishment is required, and the remaining amount of liquid medicine is small, which is convenient for handling.

[0046] In order to speed up the replenishment of medicine and fluid, there is no need to shut down the drone body. After the liquid in the outer box mounted on the drone body has drained out, the drone body can be lowered so that the outer box contacts the bottom surface, driving the buckle plate to rise, and then the bending rod is rotated along the rotating connecting rod on the connecting bracket to disengage the buckle plate from the outer box. After that, the drone body is moved to the top of the new outer box that has been loaded, and the above operation is repeated in reverse to achieve the replacement of the outer box and realize rapid replenishment of fluid and medicine.
