A seeding head 409 is fixedly arranged at the lower end of each seeding pipe 401, and the seeding head 409 is conical.

The feeding mechanism 5 further comprises three rotating wheels 504 fixedly mounted on a long shaft 503, the rotating wheels 504 are located in the blanking hopper 2, the rotating wheels 504 are located above one end, close to the blanking hopper 2, of the feeding pipe 502, the long shaft 503 is rotatably mounted on the blanking hopper 2, the feeding pipe 502 is fixedly connected with an output shaft of a speed regulating motor 501, and the speed regulating motor 501 is fixedly mounted on the bottom plate 1.

Working principle: when sowing is carried out, the connecting handle 101 fixedly arranged on the bottom plate 1 is arranged together with a mobile vehicle (such as a tricycle, a tractor and the like), and the mobile vehicle is started to pull the connecting handle 101 and the bottom plate 1 to move, and then the mobile vehicle rolls on the ground through the travelling wheels 301 to assist in moving. After the connecting handle 101 is connected with the mobile cart, a certain angle exists between the bottom plate 1 and the ground, so that the angle of the bottom plate 1 can be adjusted through the travelling mechanism 3, the distance between the seeding pipe 401 and the ground is indirectly adjusted, specifically, the travelling motor 304 is started, the output shaft of the travelling motor 304 drives the threaded rod 303 to rotate, the threaded rod 303 rotates on the bottom plate 1, the other threaded rod 303 simultaneously rotates through the belt assembly 305, when the two threaded rods 303 rotate, the sliding block 302 in threaded fit with the threaded rod 303 slides on the bottom plate 1, the travelling wheel 301 is driven to move simultaneously, the distance between the travelling wheel 301 and the seeding pipe 401 is changed, and therefore the height of the seeding pipe 401 is adjusted, namely, the depth of the seeding head 409 fixedly installed below the seeding pipe 401 extending into the ground is adjusted.

Pouring seeds into the discharging hopper 2 fixedly installed on the base plate 1 before the base plate 1 moves, the seeds do not fall into the feeding pipe 502 due to the presence of the rotating wheel 504; then the bottom plate 1 starts to move along with the seeding vehicle, meanwhile, the speed regulating motor 501 is started, the long shaft 503 is driven to rotate by the output shaft of the speed regulating motor 501, so that the rotating wheel 504 fixedly arranged on the long shaft 503 rotates, seeds falling from the blanking hopper 2 pass through the rotating wheel 504, the rotating wheel 504 can stir the seeds to enable the seeds to fall into the feeding pipe 502, and the output rotating speed of the speed regulating motor 501 is adjustable, so that the rotating speed of the long shaft 503 can be adjusted by adjusting the output rotating speed of the speed regulating motor 501, and the rotating speed of the rotating wheel 504 is adjusted, so that the speed of the seeds flowing into the feeding pipe 502, namely the seeding sparsity is realized; since the long shaft 503 is located above one end of the feeding pipe 502 near the discharging hopper 2, it can prevent seeds from blocking the port of the feeding pipe 502, and accelerate the seeds to fall into the feeding pipe 502, then the seeds poured into the discharging hopper 2 will enter into the three feeding pipes 502 respectively, the height of one end of the feeding pipe 502 located on the discharging hopper 2 is higher than that of one end of the sowing pipe 401, so the seeds entering into the feeding pipe 502 will flow into the sowing pipe 401, then be sowed into the ground through the sowing head 409 below the sowing pipe 401, and the sowing head 409 is tapered to facilitate better insertion into the ground, and reduce resistance in the moving process of the sowing pipe 401.

If the spacing between the three sowing heads 409 needs to be adjusted, the pressing plate 403 may be pressed downwards (as shown in fig. 4), so that the pressing plate 403 slides downwards along the vertical plate 404, meanwhile, the return spring 405 is compressed, the return spring 405 is used for assisting the pressing plate 403 to return, the pressing plate 403 moving downwards will leave the eight side column 402, thus the eight side column 402 is not limited to rotate, at this time, the eight side column 402 rotates, so that the eight side column 402 drives the central gear 406 to rotate, and because the central gear 406 is engaged with the two symmetrically arranged racks 407, the two racks 407 slide along the middle sowing pipe 401, and meanwhile, the sowing pipes 401 at two sides of the middle sowing pipe 401 are respectively pushed to slide along the bottom plate 1, so that the sliding groove 408 slides with the bottom plate 1, thus the distance between the three sowing pipes 401 will change, and the purpose of this is to adjust the sowing distance according to the actual sowing requirement.
