Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an agricultural UAV capable of evenly sowing seeds. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control and self-contained programmable controls, or operated fully or intermittently autonomously by onboard computers. Compared to manned aircraft, UAVs are often better suited for missions deemed "dull, dirty, or dangerous." Drones can be categorized into military and civilian applications. In the military, UAVs are divided into reconnaissance and target drones. In the civilian sector, UAVs combined with industrial applications represent a real demand for UAVs. Applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television production, and the creation of romance have greatly expanded the uses of UAVs. Developed countries are also actively expanding industrial applications and developing UAV technology.

[0003] In the agricultural field, drones generally help farmers with sowing operations. However, when using agricultural drones with existing technology, the filter screen is often easily clogged, resulting in uneven sowing of seeds by the drone, affecting the quality of planting. Therefore, there is an urgent need for an agricultural drone that can sow seeds evenly to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to provide an agricultural drone that can sow seeds evenly, which has the advantages of uniform sowing and anti-clogging, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an agricultural drone that can sow seeds evenly, comprising a drone body, a buffer stabilization component and a sowing component, wherein the sowing component is arranged on the top of the drone body, and the buffer stabilization components are arranged on both sides of the bottom of the sowing component, the sowing component comprises a mounting block, a fixing seat, a first motor, a sowing box, a vibration motor, a mounting frame, a limiting cylinder, a second spring, a positioning rod, a rotating frame, a second motor, a slider, a slide groove and a sowing plate, and the buffer stabilization component comprises a fixed base plate, a first spring, a limiting column, a positioning seat and a T-bar.

[0008] Furthermore, the positioning rod slides in the inner cavity of the limiting cylinder, the sowing box is fixedly installed on the bottom of the positioning rod, and the vibration motors are fixedly installed on both sides of the sowing box.

[0009] Furthermore, the second spring is fixedly mounted at the center of the top of the inner cavity of the mounting frame, the bottom of the second spring is fixedly connected to the top of the seeding box, and the seeding plate is fixedly mounted at the bottom of the inner cavity of the seeding box.

[0010] Furthermore, the second motor is fixedly mounted in the inner cavity of the seeding box, the rotating frame is fixedly mounted on the output shaft of the second motor, and one side of the rotating frame is rotatably connected to the inner cavity of the seeding box via a bearing.

Then the first motor is turned on, and the mounting frame is driven to rock back and forth by the first motor. Then the vibration motor is turned on, and the sowing box drives the positioning rod and the slider to move up and down under the vibration of the vibration motor. At the same time, the second motor is turned on, and the rotating frame is slowly rotated under the action of the second motor, and the seeds are evenly discharged through the sowing plate and prevented from being blocked. When the entire device falls, the entire device is buffered by the action of the first spring to prevent it from being directly hit on the ground by the force. It has the advantages of uniform sowing and anti-blocking, and solves the problem that the agricultural drone of the prior art is often prone to filter blockage when in use, resulting in uneven sowing of the drone and affecting the planting quality.
