The working principle of this utility model is specifically described as follows:

In this design, a number of screening holes are provided above the screening bin 506. After the small particles of seeds are screened, the corn seeds with full particles slide down along the transmission tube 507 into the conveying bin 508 to realize the screening function of corn particles, thereby improving the corn quality. Seedling survival rate.

In this design, when the corn precision seeder is working, the servo motor 408 is started through the control switch. The servo motor 408 drives the fourth transmission wheel 407 to rotate. The fourth transmission wheel 407 drives the third transmission wheel 405 to rotate through the second transmission belt 406. The third transmission wheel 405 drives the upper second transmission wheel 403 to rotate through the transmission rod 404 connected to it; the second transmission wheel 403 drives the first transmission wheel 401 to rotate through the first transmission belt 402; the rotation of the transmission wheel 401 drives the movable rod 303 moves, and the movement of the movable rod 303 drives the cleaning rod 307 connected to it to move; the servo motor 408 controls the up and down movement of the cleaning rod 307 through forward and reverse rotation. When the cleaning rod 307 moves upward, the bottom end of the cleaning rod 307 moves to the connecting position. When the opening of the sleeve 308 is above the opening of the connecting sleeve 308, the fertilizer falls from the opening of the connecting sleeve 308 to the seed ditch along the conduit 309 to realize the fertilization function. When the cleaning rod 307 moves downward, the bottom end of the cleaning rod 307 moves to the opening of the connecting sleeve 308. When it is downward, the cleaning rod 307 blocks the fertilizing port and stops fertilizing. The cleaning rod 307 continues to move downward to squeeze out larger fertilizer particles or stains in the conduit 309 to clean the fertilizing port and avoid clogging.

In this design, when the corn precision seeder is working, the servo motor 408 is started through the control switch. The servo motor 408 drives the fourth transmission wheel 407 to rotate. The fourth transmission wheel 407 drives the third transmission wheel 405 to rotate through the second transmission belt 406. The third transmission wheel 405 drives the rotating shaft 510 below it to rotate through the transmission rod 404, and the push plate 511 rotates around the central axis of the rotating shaft 510, pushing the corn seeds in the transport bin 508 to the opening above the sowing conduit 513. The guide tube 513 is dropped onto the seed trench to control the sowing quantity of corn.

In this design, when the corn precision seeder is working, start the tractor, and its power output shaft drives the rotating shaft 202 to rotate through the chain. The rotary blade 203 on the rotating shaft 202 rotates around the central axis of the rotating shaft 202 to rotary till the wheat stubble field. The wheat stubble and soil after rotary tillage are thrown to the gathering cavity 701 under the rotation of the rotary blade 203, and then slide down to the seed ditch under the guidance of the seed covering cavity 702 under the action of gravity; during this process, the fertilizer box The fertilizer in 301 falls to the top of the soil through the guide assembly under the guidance of the conduit 309, and falls into the soil under the action of the trenching assembly, thereby achieving the purpose of soil fertilization. At the same time, the corn seeds discharged from the sowing box body 501 fall on The seed ditch formed by the ditching assembly is covered with wheat stubble and soil mixed with wheat stubble and soil that slides down from the seed covering cavity 702 to the seed belt. The running wheels 601 not only play the role of supporting walking but also can protect the corn seeds. The covering acts as a suppressor to prevent the corn seeds from being too soft and unable to protect moisture and resist drought.

The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still implement the foregoing implementations.
