The working principle is as follows: when the corn planter is used, firstly, corn seeds to be planted are fed from the top of the precision seed planter 1, then the precision seed planter 1 carries out the bell-row operation, the separated corn seeds are sequentially conveyed to the inside of the directional adjusting assembly 2 from the bottom of the precision seed planter 1 one by one, then the directional adjusting assembly 2 detects, adjusts and conveys the corn planted by the precision seed planter 1 to convey the adjusted corn to the planting assembly 3 for planting;

when the corn of the row clock is input into the cover shell 31 from the bottom of the precision seed-metering device 1 along the input hole at the top of the cover shell 31, the corn enters the receiving groove 62 on the rotary disc 61 along the input hole, in order to erect the corn seeds 1, the thickness of the receiving groove 62 is slightly larger than that of the corn in design, the width of the receiving groove 62 is slightly larger than that of the corn, because the receiving groove 62 is in a state that the barrier plate 26 is consistent horizontally, at the moment, the barrier plate 26 blocks the first adsorption hole 65, the corn in the receiving groove 62 naturally falls to the bottom of the receiving groove 62, then the driving shaft 33 rotates along with the motor, the receiving groove 62 after receiving the corn rotates to a position above the axis of the rotary disc 61 along with the rotary disc 61, because the receiving groove 62 is moved away from the barrier plate 26, the first adsorption hole 65 is communicated with the adsorption cavity 22, and the first adsorption hole 65 and the second adsorption hole 64 adsorb and fix the corn, then, the driving unit four on the detection unit 38 is started, the test probe extends into the material receiving groove 62 along the transition hole on the partition plate 32, at this time, because one side of the corn seed is adsorbed by the adsorption hole one 65 and the adsorption hole two 64 on the material receiving groove 62, when the test probe is triggered, the thicker end of the corn is upward, the corn endosperm is above, when the test probe is not triggered, the thicker end of the corn is downward, and the corn endosperm is below;

when endosperm is detected to be positioned above, the driving unit IV is started to enable the detection probe to move to an initial position, then the driving unit II of the pushing unit 311 is started to enable the adsorption plate 91 on the pushing unit 311 to extend into the receiving groove 62 along the through hole I63, meanwhile, the air suction pump arranged on the air pipe I93 of the pushing unit 311 is started to suck air to the adsorption plate 91, so that the adsorption plate 91 adsorbs corns, then the adsorption plate 91 pushes the adsorbed corns to one side of the adjusting unit 39 along the transition hole I on the partition plate 32 along with the driving unit II, then the adjusting unit 39 is installed in the mode to adsorb and fix the corns, then the air suction pump of the pushing unit 311 is closed to stop adsorbing the corns, after the adjusting unit 39 adsorbs the corns, the driving unit I is started to enable the adsorption plate 91 to move to one end position far away from the partition plate 32, then the rotating motor is started to enable the adsorption plate 91 to rotate 180 degrees to adjust the position, finally, the corn with the direction adjusted is conveyed to the inside of the receiving trough 62 and is adsorbed and fixed by the receiving trough 62, the driving shaft 33 starts to convey the corn after the position is adjusted, when the conveyed corn moves to the position right below the driving shaft 33, the corn is not adsorbed due to the fact that the second adsorption hole 64 is communicated with the release cavity 23, and the corn slides downwards along the receiving trough 62 to enter the planting assembly 3;

when the corn is planted, the corn slides downwards along the extension pipe 11 and then is blocked by the supporting plate 101 on the bottom blocking unit 17, the corn is positioned above the supporting plate 101 at the top of the bottom blocking unit 17, then the driving unit four on the pushing pipe 15 is started, the pushing pipe 15 moves downwards, the limiting block 103 on the bottom blocking unit 17 moves towards the direction of the middle switching channel along the extension channel at the bottom of the limiting channel two 110, when the limiting block 103 on the bottom blocking unit 17 is braked to the middle switching channel, the gear 104 on the bottom blocking unit 17 moves to the position of the rack two 109, then the rack two 109 rotates the gear 104, then the supporting plate 101 deflects downwards, so that the corn can move downwards, and meanwhile, the supporting plate 101 on the top pressing unit 14 deflects in the same way to press the corn downwards from the top of the corn for planting, and the design realizes the orientation adjustment of endosperm embryo in the corn planting process, the sowing state of the corn seeds in the corn planting process is adjusted, so that the corn is kept consistent in sowing state, and particularly, the corn germs are ensured to face upwards, so that the corn is beneficial to the growth of the corn.
