By adjusting the speed of the second servo motor 305, the speed of the seeds entering the sowing bin 316 from the seed storage bin 320 is controlled, so as to achieve the purpose of adjusting the sowing speed.

[0045] Working principle and use process of the utility model: During the use of the utility model, when the adjustable seeding device for rapeseed planting is used, first, when it is necessary to adjust the distance between the first seeding machine 31 and the second seeding machine 32 for seeding, the first servo motor 210 is started to drive the belt 211 and the first gear 212 to transmit, and further drive the first gear 212 and the second gear 213 to engage and transmit, and the two-way threaded shaft 209 is driven to rotate by the second gear 213. Finally, when the two-way threaded shaft 209 rotates, the thread block 208 engages with the two-way threaded shaft 209 through the thread groove opened inside, thereby moving left and right on one side of the two-way threaded shaft 209, and the other thread block 208 moves on the other side of the two-way threaded shaft 209 at the same time. In this process, the first bracket 207 connected to the thread block 208 drives the cover plate 301, the shell 302, the base plate 303 and the slider 304 to move inside the slide groove 206 opened on the bottom plate 205.

[0046] When sowing is required, the seeds are first poured into the seed storage bin 320, and then the air pump 314 is started to transport the high-pressure gas to the inside of the sowing bin 316 through the air pipe 315. At this time, the high-pressure gas directly leaves the sowing bin 316 through the sowing hole 317;

[0047] Next, the battery 309 is started to supply power to the first wire 310;

[0048] Finally, the second servo motor 305 is started to drive the insulating disk 306 and the conductive block 307 to rotate. At this time, the electricity inside the battery 309 intermittently enters the interior of the electromagnet 312 as the first wire 310, the conductive block 307 and the second wire 311 are intermittently connected. When the electromagnet 312 is energized, a magnetic force is generated to attract the magnetic block 313, thereby driving the pry bar 321 to deflect, and finally driving the sealing ring 325 at the other end of the pry bar 321 to open between the sowing bin 316 and the seed storage bin 320, and the seeds enter the sowing bin 316 from the seed storage bin 320; when the electromagnet 312 is powered off, the magnetic force disappears. At this time, under the elastic force of the spring 322, the pry bar 321 is reset, and the seeds cannot enter the sowing bin 316. By adjusting the rotation speed of the second servo motor 305, the speed at which the seeds enter the sowing bin 316 from the seed storage bin 320 is controlled, thereby achieving the purpose of adjusting the sowing speed.
