Description

Technical Field

[0001] The present application relates to the technical field of special-purpose drones, and in particular to a seeding drone. Background Art

[0002] With the development of drone technology, people have begun to explore the application of drones in agriculture. For example, domestic and foreign companies have developed various types of sowing drones. Using drones to sow seeds to every corner of the farmland is one of the most efficient sowing methods. While freeing up people's labor, it can also make the seeds sown evenly, so drone sowing has gradually become a trend of the times.

[0003] When the existing special-purpose seeding drones are performing seeding operations, due to the difference in seed size, the larger gap between the seeding guide rollers cannot evenly sow smaller seeds, while the smaller gap between the seeding guide rollers cannot sow larger seeds. This requires the replacement of suitable seeding guide rollers before sowing, which is cumbersome and not conducive to the rapid sowing of the seeding drone. Secondly, when the existing dual-guide roller seeding drones are sowing, there will be areas where seeds overlap, resulting in a higher seed density in this area, affecting the uniformity of seed sowing. Summary of the invention

[0004] The present application proposes a seeding drone, which has the advantage of quickly adjusting the spacing between the seeder guide rollers, so as to solve the problem that the existing drones need to replace suitable seeder guide rollers before sowing seeds, which is cumbersome to replace and not conducive to rapid sowing by the seeding drone.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a seeding drone, comprising: a drone body, a controller is fixedly installed on the front of the drone body, two connecting seats are fixedly connected to the bottom surface of the drone body, a material box is fixedly connected to the bottom surfaces of the two connecting seats, box covers are movably installed on both sides of the top of the material box, a frame is arranged in the middle of the connecting seat, two connecting plates are connected between the frame and the material box, an inner air outlet shell is fixedly connected to the middle of the bottom surface of the material box, an air guide seat is fixedly connected to the front of the inner air outlet shell, and the A driving motor is arranged at the rear of the inner air outlet shell, a driving wheel is fixedly connected to the output shaft of the driving motor, bottom plates fixedly connected to the material box are arranged on both sides of the inner air outlet shell, an outer side of the bottom plate is fixedly connected to an outer air outlet shell, an air guide pipe is fixedly connected to the front of the outer air outlet shell, a control valve is fixedly installed in the middle of the air guide pipe, a material spreading mechanism is arranged inside the bottom plate, a transmission wheel is fixedly installed at the rear of the material spreading mechanism on the right side, a synchronous belt is transmission-connected between the transmission wheel and the driving wheel, and an air suction mechanism is arranged on the front of the outer air outlet shell.

[0006] Preferably, the material spreading mechanism includes a transmission shaft, a fixed plate and a spur gear are fixedly installed on the rear part of the transmission shaft, a plurality of partitions are fixedly connected to the edge of the fixed plate, a multi-stage cover plate is installed between two adjacent partitions, two electric telescopic rods are fixedly installed inside the fixed plate, a plurality of circular plates are slidably connected to the front part of the transmission shaft, and a compression spring and a plurality of airbags are fixedly connected between two adjacent circular plates.

[0007] Preferably, the air suction mechanism includes a column, an air guide hood is fixedly connected to the front side of the column, an air suction cavity is opened inside the column, a shaft is arranged in the middle of the air suction cavity, and an air suction fan blade is fixedly connected to the middle of the shaft.

[0008] Preferably, the frame is fixed to the upper surface of the material box by a connecting seat, the interior of the inner gas outlet shell is connected to the interior of the gas guide seat, and a plurality of gas outlet holes are provided at the bottom of the inner gas outlet shell and the outer gas outlet shell.

[0009] Preferably, the two spur gears are meshed with each other, the telescopic end of the electric telescopic rod is fixedly connected to the rearmost circular plate, the circular plate is matched with the bottom plate, and the interior of the airbag is filled with a proper amount of compressed gas.

[0010] Preferably, the column is fixedly connected to the base plate, the shaft is fixedly connected to the transmission shaft, the shaft and the transmission shaft are both rotatably connected to the base plate, and the air suction cavity is communicated with the air guide seat and the air guide pipe.

[0011] Preferably, the transmission wheel is fixedly connected to the transmission shaft on the right side, the transmission wheel is located behind the spur gear, the fixing plate is located inside the bottom plate, and the spur gear is located at the rear of the bottom plate.

[0012] Preferably, the innermost cover plate of the multi-stage cover plate is fixedly connected to the circular plate at the rear, and the outermost inner cover plate is fixedly connected to the partition plate.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention controls the telescopic length of the electric telescopic rod through a controller. The extension of the electric telescopic rod will push the circular plate to move forward, thereby shortening the distance between the multiple circular plates and squeezing the compression spring and the airbag. Under the action of the compression spring and the airbag, the distance between two adjacent circular plates is equal. During the extension of the electric telescopic rod, the multi-stage cover plate will slide and extend, and the airbag will expand outward due to squeezing, thereby changing the depth of the grooves between the circular plates to adapt to the size of the seeds, thereby solving the problem that the existing drone needs to replace the appropriate seeder guide roller before sowing seeds, which is cumbersome to replace and is not conducive to the rapid sowing of the sowing drone.

[0014] 2. The present invention draws air through the rotating suction fan blades, and supplies the gas to the inside of the air guide seat and the inner air outlet shell, and finally sprays it downward. The sprayed gas will cause the seeds sown directly below to fall quickly, thereby preventing the seeds sown on both sides from crossing. This solves the problem that when the existing double-guide roller sowing drone is sowing, there will be an area where seeds overlap, resulting in a high seed density in this area, affecting the uniformity of seed sowing.

[0015] 3. When sowing at the edge of the plot, the control valve near the edge of the plot will open, and the gas sucked by the air suction fan blades will enter the outer air shell through the air guide pipe and finally be discharged from the bottom of the outer air shell. The ejected gas will cause the seeds sown directly below to fall quickly, avoiding the seeds falling outside the sowing area due to the long landing time and the horizontal speed when thrown out. When sowing in windy weather, the control valves on both sides are opened, and the outer air shells on both sides eject gas, thereby accelerating the fall of seeds and reducing the impact of wind on sowing uniformity.

The rotating air suction blades 195 suck air and supply the gas to the inside of the air guide seat 9 and the inner air outlet shell 8, and finally spray it downward. The sprayed gas will cause the seeds sown directly below to fall quickly, thereby preventing the seeds sown on both sides from crossing, and thus making the middle area plot have a higher sowing density; When sowing at the edge of a plot, the control valve 15 near the edge of the plot will be opened, and the gas sucked by the suction fan blades 195 will enter the outer air shell 13 through the air duct 14, and finally be discharged from the bottom of the outer air shell 13.
