during operation, a worker places a proper amount of corn seed particles in each storage hopper 230 in advance, then the device moves forward under the traction action of an agricultural tractor, when the device moves forward integrally, the wheels 130 roll on the ground under the action of relative friction with the ground, the corresponding discs 310 continuously rotate through the transmission connection of the belt pulley transmission mechanism 160, when the discs 310 continuously rotate, the rod barrels 320 rotatably connected to the outer edge positions of the discs are driven to rotate and swing, the cross beams 280 rotatably connected to the lower parts of the first screw rods 340 are driven to reciprocate up and down through the rod barrels 320 and the first screw rods 340, and the discharging pipes 220 are driven to reciprocate up and down in the fixed frame 210 through the cross beams 280;

in operation, when the blanking pipe 220 moves downwards, the first gear 264 in the material distributing assembly 260 inside the material distributing barrel 240 is driven to move downwards, since the bar 265 is fixed to the bottom of the fixed frame 210 in a fixed state, the opposite first gear 264 is moved downward, and, by means of the tooth engagement between the first gear 264 and the first rack 266, the first gear 264 is rotated, and the shaft barrel 261 connected with the first gear 264 is driven to rotate in the material separating barrel 240 during the rotation process of the first gear 264, thereby rotating the three groups of partition plates 262 uniformly fixed on the outer side of the shaft barrel 261, rotating and moving the storage space formed above the inner part of the material separating barrel 240 downwards, communicating the storage space with the bottom port of the blanking pipe 220 after rotating, the arc-shaped plates 263 are fixedly connected among the three groups of partition plates 262, and the corn seeds above the blanking pipe 220 are prevented from falling downwards in the rotating process of the shaft barrel 261 by plugging of the arc-shaped plates 263;

when the corn harvester works, corn seeds in the storage hopper 230 enter a storage space formed in the distributing cylinder 240 along the discharging pipe 220 under the action of gravity to be quantitatively stored, when the discharging pipe 220 moves downwards to drive the storage space to rotate, the corn seeds in the storage space move downwards along with the storage space, and when the storage space is communicated with a bottom port of the discharging pipe 220, the corn seeds in the storage space fall downwards under the action of gravity to be discharged;

when the device works, the blanking pipe 220 drives the soil breaking component 250 arranged below the blanking pipe to move downwards in the downward movement process, the support plate 255 moves downwards to break into the soil, when the supporting plate 255 is pressed and blocked by soil after reaching a certain depth, the supporting plate 255 is difficult to move downwards, the blanking pipe 220 continues to move downwards to drive the supporting cylinder 252 to move downwards, the supporting cylinder 252 and the supporting rod 253 are pressed and contracted, under the relative action, the push rod 256 rotates outwards to support the soil distributing hopper 251 to expand outwards, the soil separation bucket 251 pushes the soil separation bucket to enable the soil to be in a pit kiln, corn seeds falling from the lower end of the blanking pipe 220 fall into the pit kiln supported by the soil separation bucket 251, during the downward movement of the blanking pipe 220, the second gear 272 moves downward relative to the bar 265, and the corresponding two sets of covering claws 271 are rotated outward and spread by means of the tooth engagement between the second gear 272 and the second rack 273;

during operation, in the upward movement process of the discharging pipe 220, the soil breaking assembly 250 is driven to move upward to exit the soil, under the elastic supporting action of the spring 254, the supporting cylinder 252 and the supporting rod 253 are unfolded and reset again, so that the push rod 256 is rotated and reset to pull the corresponding two-component soil hopper 251 to be closed, and synchronously, in the upward movement process of the discharging pipe 220, the second gear 272 moves upward and resets relative to the second rack 273, so that the corresponding two groups of soil covering claws 271 are folded and closed towards the middle, and soil protruding on the ground surface is gathered and covered above the pit kiln through the closing of the soil covering claws 271, so that automatic soil covering operation is realized;

during operation, when the worker needs to adjust the positions of the two middle groups of fixed frames 210, the worker rotates the second screw 420 and drives the screw 410 to move on the second screw 420 by means of the thread meshing between the second screw 420 and the screw 410, so that the positions of the corresponding fixed frames 210 are adjusted, and the distance between the two middle groups of ground breaking assemblies 250 during seeding is flexibly adjusted;

during operation, when the sowing depth needs to be adjusted, a worker rotates the nut 330, and drives the first screw 340 to move in the nut 330 by means of the thread engagement between the nut 330 and the first screw 340, so that the first screw 340 moves in the nut 330, is adjusted to move, and changes the supporting length of the rod cylinder 320 and the first screw 340, thereby adjusting the lifting sliding distance of the blanking pipe 220, so as to facilitate sowing operations at different depths;

when the corn seed storage device works, when the seed storage amount in the storage space needs to be adjusted, a worker can remove the cap on the back surface of the material separating cylinder 240 through rotation, the bolt 269 is rotated and driven by means of threaded engagement between the bolt 269 and the screw cylinder 268, so that the bolt 269 moves upwards in the screw cylinder 268, the position of the movable spring plate 267 is jacked, the position of the storage space is changed, the uniform discharge amount of corn seeds is conveniently and flexibly controlled, and the whole working principle is adopted.
