[0030] In one embodiment, as Figure 3 and Figure 4As shown, the adjustment assembly includes a transition box 501. The top of the transition box 501 is fixedly connected to the strip-shaped through hole 403. The bottom of the transition box 501 is provided with a seed metering box 502. A rotating column 503 is fixedly connected to the inner bottom wall of the seed metering box 502. A first synchronous pulley 504 and a second synchronous pulley 505 are respectively provided at the tops of the two rotating columns 503. A synchronous belt 506 is provided between the first synchronous pulley 504 and the second synchronous pulley 505. Curved blades 507 are provided around the rotating column 503. A seed outlet 508 is provided on one side of the seed metering box 502. By rotating the rotating column 503, the rotating column 503 drives the curved blades 507 to rotate. The seeds discharged from the transition box 501 first fall into the curved blades 507, and the curved blades 507 rotate the seeds to the seed outlet 508 and discharge the seeds. The rotation speed of the rotating column 503 can be controlled to adjust the rotation speed of the curved blades 507, and thereby adjust the discharge speed of the seeds, so that the seeding density can be correspondingly adjusted.

[0031] In one embodiment, as Figure 4 shown, the inner bottom wall of the seed metering box 502 is a curved surface structure that is high in the middle and low around; by the inclined setting of the seed metering box 502, it is convenient for the seeds to smoothly slide into the seed outlet 508.

[0032] In one embodiment, as Figure 4 shown, a motor 601 is fixedly connected to the bottom of the seed storage box 200. The output end of the motor 601 is fixedly connected to the top of the first synchronous pulley 504; by starting the motor 601, the first synchronous pulley 504 is driven to rotate.

[0037] The working principle of the present utility model is as follows: The above-described embodiment discloses a helicopter seeding device with adjustable seeding density. Among them, in the normal state, the opening and closing plate 402 covers the strip-shaped through hole 403. When seeding is required, first, start the electric push rod 401, so that the electric push rod 401 drives the opening and closing plate 402 to disengage from the strip-shaped through hole 403, opening the connection between the strip-shaped through hole 403 and the transition box 501. Seeds fall into the transition box 501 through the strip-shaped through hole 403. At this time, start the motor 601, so that the motor 601 drives the first synchronous wheel 504 to rotate. Under the action of the synchronous wheel 506, the first synchronous wheel 504 drives the second synchronous wheel 505 to rotate, enabling the two rotating columns 503 to move synchronously. After the rotating column 503 rotates, it drives the curved blade 507 to rotate. The seeds discharged from the transition box 501 first fall into the curved blade 507, and the curved blade 507 rotates the seeds to the seed outlet 508 and discharges the seeds. The rotation speed of the curved blade 507 can be adjusted by controlling the rotation speed of the rotating column 503, and accordingly, the discharge speed of the seeds can be adjusted, thereby enabling the seeding density to be adjusted accordingly.
