Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a powder blowing device based on an unmanned aerial vehicle platform. Background Art
[0002] In the traditional agricultural production process, farmers' operations such as fertilizing, blowing pesticides, and preventing pests and diseases mostly rely on experience, and are labor-intensive and inefficient. With the popularization of drones, drones are providing a modern, efficient, and low-cost plant protection method for agriculture. For example, using drones for high-altitude spraying can accurately spray crops, which not only improves work efficiency, but also reduces environmental pollution and labor costs. At present, most common spreading equipment on the market is a disk structure, which is highly applicable to seeds and large-particle fertilizers. However, in actual production, many materials are in powder form, and the conventional disk-type particle spreading method using centrifugal force is not effective. In order to solve the above problems, it is urgent to design a powder blowing equipment based on a drone platform. Utility Model Content
[0003] The utility model provides a powder spreading device based on an unmanned aerial vehicle platform, which solves the problem that the conventional disk-type spreading in the prior art has poor effect in spreading powder.
[0004] The technical solution of the utility model is achieved in this way:
[0005] A powder blowing device based on an unmanned aerial vehicle platform comprises a silo fixed on the unmanned aerial vehicle, wherein the bottom of the silo is connected with a lower silo through a lower silo, a sleeve is rotatably connected with the lower silo through a pin shaft, a lower silo side wall is provided with a lower silo plate and a windward plate inclined toward the silo, the lower silo plate, the sleeve and the windward plate constitute a windward control plate, a limit plate is fixed on the inner wall of the lower silo, the limit plate is between the windward plate and the lower silo, the lower silo corresponds to the lower silo, when the lower silo plate abuts against the silo at the lower silo, the windward control plate, the lower silo and the limit plate form a sealed cavity; an airway is connected with an airway below the lower silo, an axial flow fan is provided in the airway, the axial flow fan blows the windward control plate to rotate, an adjusting device is provided on the windward control plate, the adjusting device makes the windward plate in a windless state away from the limit plate.
[0006] Furthermore, the adjustment device includes a counterweight lever, which is L-shaped, one end of which is fixedly connected to the feed plate, and the other end is inclined toward the windward plate, and a diamond-shaped counterweight is fixed to the inclined end. The gravity of the counterweight applies an upward rotational pulling force to the feed plate, so that the feed plate is against the bottom of the silo, and the sharp corners of the diamond-shaped counterweight facilitate the squeezing of the powder, thereby reducing the resistance of the powder to the counterweight.
[0007] Furthermore, the unloading plate is fixedly connected with a guide plate tilted downward, and one side of the guide plate abuts against the unloading port. The sharp angle formed by the guide plate tilted downward and the unloading plate can squeeze the powder through the sharp angle, thereby reducing the resistance of the powder to the rotation of the unloading plate.
[0008] Furthermore, a flow stabilizer is fixedly connected to the outer wall of the lower silo, and the flow stabilizer blocks the air outlet of the airway. The flow stabilizer can block the airway outlet to prevent the turbulence caused by the rotation of the propeller of the drone from circling the wind field at the airway outlet, so that the powder can be evenly spread.
[0009] Furthermore, the weight of the windward plate is greater than that of the unloading plate. The unloading plate and the silo are offset by the windward plate's own weight, and no additional power device is needed to drive the unloading plate to rotate, thereby achieving the effect of energy saving.
[0010] Furthermore, the adjusting device is a torsion spring, and the sleeve is rotatably connected to the pin shaft through the torsion spring. The torsion spring applies torque to the windward plate, so that the unloading plate is against the bottom of the silo to prevent the powder from falling.
[0011] Beneficial effects:
[0012] The utility model uses an axial flow fan to blow powder so that the powder can be sprayed evenly. The wind force can be adjusted by adjusting the wind speed of the axial flow fan, and then the gap size between the feed plate and the bin body can be adjusted, thereby improving the accuracy and stability of powder spraying. The limit plate can prevent the windward plate from rotating too much, and can provide support force for the feed plate to prevent the gap from opening too large, resulting in the powder not being blown evenly. The utility model has a high degree of automation, can reduce manual operations, improve production efficiency, and has a good effect on spraying powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figures 1 to 5 As shown, the embodiment of the utility model provides a powder blowing equipment based on the UAV 1 platform, including a silo 2 fixed on the UAV 1, the bottom of the silo 2 is connected with a lower silo 8 through a lower feed port, a sleeve is rotatably connected in the lower silo 8 through a pin shaft, and the side wall of the sleeve is provided with a lower feed plate and a windward plate inclined toward the silo 2, the lower feed plate, the sleeve and the windward plate constitute a windward control plate 5, a limit plate is fixed on the inner wall of the lower silo 8, the limit plate is between the windward plate and the lower feed plate, the lower feed plate corresponds to the lower feed port, when the lower feed plate and the silo 2 at the lower feed port are against each other, the windward control plate 5, the lower silo 8 and the limit plate form a sealed cavity; the lower part of the lower silo 8 is connected with an airway 3, an axial flow fan 4 is arranged in the airway 3, the axial flow fan 4 blows the windward control plate 5 to rotate, and an adjusting device is arranged on the windward control plate 5, and the adjusting device makes the windward plate in a windless state away from the limit plate.
[0022] When the UAV 1 is in the off state, the windward plate rotates away from the limit plate under the action of the adjustment device, and drives the unloading plate to rotate toward the silo 2. When the unloading plate abuts against the silo 2, the windward control plate 5, the unloading silo 8 and the limit plate form a sealed cavity and prevent the powder in the silo 2 from falling.
[0023] When powder blowing is required, powder is added to the silo 2, and the power supply is the axial flow fan 4. The axial flow fan 4 blows the windward plate to overcome the resistance of the adjusting device and rotate. The windward plate drives the unloading plate to rotate in the direction away from the silo 2, and the gap is opened for powder unloading. After the powder falls into the airway 3, it is ejected with the high-speed airflow of the axial flow fan 4 to complete the blowing of the powder. The high-speed airflow of the axial flow fan 4 will form a negative pressure at the unloading port, attracting the powder at the unloading port for unloading, so as to prevent the powder from being blocked. The wind speed of the axial flow fan 4 can be adjusted to adjust the wind force, thereby achieving the effect of adjusting the gap size. The limit plate can prevent the windward plate from rotating too much, and can provide support for the unloading plate to prevent the gap from opening too large, resulting in the powder not being evenly blown.
[0024] The adjustment device includes a counterweight lever 6, which is L-shaped, one end of which is fixedly connected to the blanking plate, and the other end is inclined toward the windward plate, and a diamond-shaped counterweight is fixed to the inclined end. When the drone 1 is turned off, the counterweight fixedly connected to the counterweight lever 6 exerts an upward rotational pulling force on the blanking plate by its own gravity, so that the blanking plate is closed, and the sharp corners of the diamond-shaped counterweight facilitate the squeezing of powder, thereby reducing the resistance of the powder to the counterweight.
[0025] The unloading plate is fixedly connected with a guide plate tilted downward, and one side of the guide plate abuts against the unloading port. The sharp angle formed by the guide plate tilted downward and the unloading plate can squeeze the powder through the sharp angle to reduce the resistance of the powder to the rotation of the unloading plate, and the guide plate tilted downward can provide a guiding effect for the powder to prevent the powder from entering the axial flow fan 4.
[0026] The outer wall of the lower bin 8 is fixedly connected with a flow stabilizer 7, which blocks the air outlet of the airway 3. The flow stabilizer 7 can block the outlet of the airway 3 to prevent the turbulent flow of the propeller of the drone 1 from rotating around the wind field at the outlet of the airway 3, so that the powder can be evenly spread.
[0027] The weight of the windward plate is greater than that of the unloading plate. The unloading plate is rotated by the weight of the windward plate itself to counteract the silo 2, and no additional power device is needed to drive the rotation of the unloading plate, thereby achieving the effect of energy saving.
[0028] The adjusting device is a torsion spring, and the sleeve is rotatably connected to the pin shaft through the torsion spring. The torsion spring applies torque to the windward plate, so that the windward plate rotates away from the limit plate, and the windward plate drives the unloading plate to rotate upward, and the unloading plate abuts against the silo 2 to prevent the powder from falling.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
