Description

Technical Field

[0001] The utility model relates to a planting unmanned aerial vehicle spraying device, belonging to the technical field of planting unmanned aerial vehicles. Background Art

[0002] Plant protection UAV, also known as unmanned aerial vehicle, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. It can spray pesticides, seeds, powders, etc. through ground remote control or navigation flight control.

[0003] After searching, it was found that the wind-proof spraying device for a crop protection drone described in the authorization announcement number CN217864764U has the following beneficial effects: by rotating the telescopic rod and the connecting rod, the spray port can be extended from under the blade to prevent the high-speed airflow generated during the operation of the plant protection machine from affecting the uniformity of the spraying, and the spray width can be adjusted by adjusting the telescopic rod, greatly increasing practicality.

[0004] In actual use, if there are structures such as wave-breaking plates on the surface of the internal medicine storage tank, the plant protection machine will be affected by external gases and liquid fluctuations, and its stability will be greatly reduced. Its usage defects are quite obvious and urgently need to be improved. Therefore, a planting drone spraying device is needed for people to use. Utility Model Content

[0005] The purpose of the utility model is to provide a planting drone spraying device. When spraying, an electric telescopic rod is used to move the spray nozzle downward and away from the driving blades. The spray pump draws the liquid medicine, which is sprayed out from the nozzle after flowing through the spray pipe and the connecting pipe. When spraying, since the nozzle is far away from the blades, the high-speed airflow generated during the operation of the plant protection machine can be prevented from affecting the uniformity of the spraying. In addition, with the use of the plant protection machine, the liquid medicine in the liquid storage tank can reduce the fluctuation and impact of the liquid under the action of the fixed wave-breaking plate, thereby improving the stability of the use of the plant protection machine. As the spraying work proceeds, the liquid level sensor can monitor the liquid level in real time. When the liquid level is too low, the warning light can alert people to replenish the liquid in time through the liquid replenishing tube, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A planting drone spraying device comprises a mounting chassis, wherein the outer sides of the mounting chassis are fixedly connected with fixed support plates, the top of the fixed support plates is fixedly connected with a driving motor, the main shaft of the driving motor is fixedly connected with a driving blade via a coupling, the bottom end surface of the mounting chassis is fixedly connected with fixed legs, and the number of the fixed legs is four and evenly distributed at the four corner positions of the bottom of the mounting chassis, the inner side of the mounting chassis is fixedly connected with a liquid storage tank, the inner side of the mounting chassis is fixedly connected with a spray pump, the output end of the spray pump is connected with a spray pipe, and the other two ends of the spray pipe are connected with connecting pipes.

[0008] Furthermore, the connecting pipe is a telescopic pipe, and the other end of each connecting pipe is connected to a spray nozzle.

[0009] Furthermore, the bottom end surface of each fixed support plate is fixedly connected to an electric telescopic rod, and the other end of each electric telescopic rod is fixedly connected to the spray nozzle.

[0010] Furthermore, a fixed wave-breaking plate is fixedly connected to the inner side of the liquid storage tank, and there are multiple fixed wave-breaking plates which are evenly and equidistantly distributed.

[0011] Furthermore, each of the fixed wave-breaking plates is provided with a liquid through hole on its inner side, and the liquid through holes are arranged in a staggered manner, and each of the fixed wave-breaking plates is provided with a flow guide hole on its inner side.

[0012] Furthermore, a liquid level sensor is fixedly connected to the inner side of the liquid storage tank, a warning light is fixedly connected to the top of the mounting chassis, and a liquid replenishing pipe is connected to the top of the liquid storage tank.

[0013] The beneficial effects of the utility model are:

[0014] Through the set spray nozzle, electric telescopic rod, fixed wave-breaking plate and liquid level sensor, when in use, the driving motor is used to rotate the driving blade to raise the equipment, and after the equipment is raised to an appropriate height, when spraying, the electric telescopic rod is used to move the spray nozzle downward, and the nozzle is moved away from the driving blade. The medicine liquid is drawn by the spray pump and sprayed out from the nozzle after flowing through the spray pipe and the connecting pipe. When spraying, since the nozzle is far away from the blade, the high-speed airflow generated during the operation of the plant protection machine can be prevented from affecting the uniformity of spraying. In addition, with the use of the plant protection machine, the medicine liquid in the liquid storage tank can reduce the fluctuation and impact of the liquid under the action of the fixed wave-breaking plate, thereby improving the stability of the use of the plant protection machine. As the spraying work progresses, the liquid level sensor can monitor the liquid level in real time. When the liquid level is too low, the warning light can alert people to replenish the liquid in time through the refilling tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As a preferred technical solution of the utility model, a fixed wave-breaking plate 12 is fixedly connected to the inner side of the liquid storage tank 6, and the number of the fixed wave-breaking plates 12 is multiple and evenly distributed at equal intervals. A liquid through hole 13 is opened on the inner side of each fixed wave-breaking plate 12, and the liquid through holes 13 are staggered. A diversion hole 14 is opened on the inner side of each fixed wave-breaking plate 12, which reduces the fluctuation and impact of the liquid inside the liquid storage tank 6 and improves the stability of the plant protection machine.

[0025] Example 2 Please refer to Figure 1 and 2 The difference between this embodiment and embodiment 1 is that:
