[0052] In embodiment 2, the corn seed precision seeder provided in embodiment 1 is further optimized, specifically as follows: Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 5 As shown, the fertilizer assembly 6 includes the upper arc plate 601 fixedly installed above the rear end of the discharge plate 303, and the curved arc plate 602 is fixedly connected below the upper arc plate 601. The discharge plate 303 is fixedly connected with the partition plate 605 above the hopper 302, and the inner arc plate 603 is fixedly connected to one end of the partition plate 605 away from the fan-shaped arc plate 308. The inner arc plate 603 is fixedly connected to the bottom end of the curved arc plate 602 in the middle, and a fertilizer storage space is formed between one side of the inner arc plate 603 and the curved arc plate 602. The other side of the inner arc plate 603 and the space formed by the fan-shaped arc plate 308 are isolated from the fertilizer storage space. The lower edge of the feed window 607 in the inner arc plate 603 is connected to the curved arc plate 602, which serves as the connection between the two spaces. The arc-shaped plate 314 is fixedly connected to the material blocking arc plate 604 away from the positioning cylinder 317, and the material blocking arc plate 604 is movably connected to the inner arc plate 603. The fertilizer is introduced through the gap between the upper arc plate 601 and the blocking plate 708, passes through the feed window 607 of the inner arc plate 603 along the curved arc plate 602, enters the space between the material blocking arc plate 604, the arc-shaped plate 314 and the positioning cylinder 317, and then the rotation of the positioning cylinder 317 drives the material blocking arc plate 604 at one end of the arc-shaped plate 314 to rotate, which opens the feed window 607 of the inner arc plate 603. The fertilizer passes through the feed window 607 and enters the space between the arc-shaped plate 314, the positioning cylinder 317 and the material blocking arc plate 604. After the positioning cylinder 317 continues to rotate, the material blocking arc plate 604 at one end of the next arc-shaped plate 314 blocks the feed window 607 of the inner arc plate 603, thereby completing the single fertilizer introduction. Under the cooperation of gravity, the fertilizer slides along the inner wall of the material blocking arc plate 604 and is discharged, and the fertilizer falling on the inner wall bottom of the inner arc plate 603 is pushed out of the inner arc plate 603 by the next arc-shaped plate 314, thereby realizing the fertilization operation of the corn seeds.

[0053] By rotating the positioning cylinder 317, the material blocking arc plate 604 at one end of the arc plate 314 is driven to rotate, the inlet window 607 of the inner arc plate 603 is opened, and the fertilizer enters the space between the arc plate 314, the positioning cylinder 317 and the material blocking arc plate 604 through the inlet window 607. After continuing to rotate, the material blocking arc plate 604 blocks the inlet window 607, and the fertilizer slides along the material blocking arc plate 604 under the cooperation of gravity, passes through the discharge window 606, and can be carried in a rotating manner, and under the cooperation of gravity, naturally slides into the vicinity of the corn seeds, so as to realize the process of precision seeding of corn seeds and synchronous fertilization, and improve the efficiency of corn seed sowing.

[0054] Further, as shown in Figure 11 With Figure 1 , the inner arc plate 603 is provided with an inlet window 607 near one side of the curved arc plate 602, and the fertilizer stored through the inlet window 607 is introduced into the space between the inner arc plate 603 and the discharge disc 303, so as to perform the fertilization operation. The inner arc plate 603 is provided with a discharge window 606 below the hopper 302, and the fertilizer and corn seeds are discharged through the discharge window 606.

[0055] In example 3, the corn seed precision seeder provided in examples 1 and 2 is further optimized, specifically, as shown in Figure 2 , Figure 3 , Figure 9 With Figure 12As shown, the material distribution assembly 7 includes two sealing plates 706 symmetrically and uniformly movably mounted on the inner wall of the two sealing ring plates 316, and the two sealing plates 706 are fixedly connected with a support pipe 705 in the middle, the support pipe 705 is fixedly connected with a side window pipe 707 in the middle, and the side window pipe 707 is in the middle of the two sealing plates 706, the outer wall of the side window pipe 707 is fixedly connected with two baffles 708 symmetrically and uniformly, and the two baffles 708 are movably connected with the inner wall of the positioning cylinder 317 away from one end of the side window. The air pump 702 works to generate suction, the suction is guided by the fixed pipe 703, and the suction is shunted by the plurality of curved pipes 704, introduced into the support pipe 705, passed through the side window pipe 707, and then entered into the positioning cylinder 317, passed through the double-diameter inner pipe 315 in the arc plate 314 to be sucked, and the rotation of the positioning cylinder 317 rotates the arc plate 314 outside the outer wall of the positioning cylinder 317 in the inner arc plate 603. Since the tube diameter of the double-diameter inner pipe 315 close to one end of the discharge hole 309 is greater than the tube diameter close to the positioning cylinder 317, as the arc plate 314 moves between the two baffles 708, the space between the two baffles 708 in the side window pipe 707 has suction at this time. One end of the double-diameter inner pipe 315 in the arc plate 314 is aligned with the discharge hole 309 in the fan arc plate 308, and the other end is between the two baffles 708 to form an angle, so that the corn seeds are guided and sucked into the double-diameter inner pipe 315, thereby adapting to different sizes of seeds. As the positioning cylinder 317 continues to rotate, the arc plate 314 is separated from the angle space formed by the two baffles 708 to lose suction. The front end diameter of the double-diameter inner pipe 315 is greater than the diameter of the corn seed, and the rear end diameter is less than the diameter of the corn seed, so that the corn seed is adsorbed into the double-diameter inner pipe 315, passes through the front end diameter of the double-diameter inner pipe 315, and is adsorbed in the port in front of the rear end diameter, such as Figure 9 After the suction is lost, the corn seed falls back to the front end of the double-diameter inner pipe 315 and is blocked by the fan arc plate 308. The double-diameter inner pipe 315 continues to move under the driving of the rotating positioning cylinder 317 and rotates below the inner arc plate 603. The corn seed in the double-diameter inner pipe 315 falls and falls through the discharge window 606 to the discharge plate 305.

[0056] The suction force is provided for the positioning cylinder 317 by the air pump 702, the fixed cylinder, the curved pipe 704 and the support pipe 705, and then the suction force passes through the double-diameter inner pipe 315 in the arc-shaped plate 314, because the pipe diameter near the one end of the discharge hole 309 is larger than the pipe diameter near the one end of the positioning cylinder 317, when the arc-shaped plate 314 moves to between the two baffles 708, the space between the two baffles 708 at the angle is provided with the suction force, one end of the double-diameter inner pipe 315 in the arc-shaped plate 314 is aligned with the discharge hole 309 in the fan-shaped arc plate 308, and the other end is at the angle formed between the two baffles 708, so that the corn seeds enter the double-diameter inner pipe 315, with the rotation of the positioning cylinder 317, the arc-shaped plate 314 is separated from the angle between the two baffles 708, the double-diameter inner pipe 315 in the arc-shaped plate 314 loses the suction force, the corn seeds are stored in the double-diameter inner pipe 315, and after rotating to the discharge window 606, the corn seeds are separated from the double-diameter inner pipe 315, so that the equal amount of seeds can be taken by the pipeline guided suction force, the corn seeds are alternately transported by the multiple pipelines with central rotation, the equal amount of positioning and sowing is realized, and the double-diameter pipeline with the suction force can adapt to corn seeds of different sizes, and the efficiency of the precision corn seed sowing is improved.

[0059] The use process of the corn seed precision sowing machine is as follows:

[0060] Working principle: the workers are connected with the agricultural driving device by the bridge 2, and after the completion, the corn seeds are dropped into the hopper 302, and the fertilizer is introduced from the gap between the upper arc plate 601 and the baffle 708, and then passes through the feeding window 607 of the inner arc plate 603 along the curved arc plate 602, enters the space between the blocking arc plate 604, the arc plate 314 and the positioning cylinder 317, and the blocking arc plate 604 blocks the feeding window 607 of the inner arc plate 603 to prevent the fertilizer from entering the inner arc plate 603 during the non-starting process;

[0061] Starting: the air pump 702 on the horizontal bar 1 works to generate suction, the suction is guided by the fixed pipe 703, and is shunted by the plurality of curved pipes 704, introduced into the supporting pipe 705, passes through the side window pipe 707, and then enters the positioning cylinder 317, passes through the double-diameter inner pipe 315 in the arc plate 314 to suck, and at the same time when the air pump 702 works, the motor 310 drives the side gear 313 to rotate, and the gear ring 312 connected with the side gear 313 rotates, provides power for the positioning cylinder 317 at the same time, drives the positioning wheel 311 to rotate, and the rotating positioning wheel 311 drives the transmission wheel 304 to rotate under the power transmission of the transmission belt 319, drives the storage wheel 318 installed on the outer wall of the rotating shaft 307 to rotate through the rotating shaft 307 as the transmission medium;

[0062] Feeding: the corn seeds fall into the hopper 302, and the bottom of the hopper 302 is limited by the two inclined arc plates 306 and the fan arc plate 308, so that the corn seeds fall into the trough of the storage wheel 318 in turn, and at the same time, the storage wheel 318 is driven to rotate by the rotating shaft 307, the trough in the storage wheel 318 carries and drives the corn seeds, so that when the arc plate 314 far away from one end of the positioning cylinder 317 aligns with the discharge hole 309, the double-diameter inner pipe 315 sucks the corn seeds in the trough through the discharge hole 309, so as to carry out equal material taking operation;

[0063] Seeding: the rotation of the positioning cylinder 317, the arc plate 314 on the outer wall of the positioning cylinder 317 rotates in the inner arc plate 603, because the diameter of the double-diameter inner tube 315 near the outlet hole 309 is larger than the diameter near the positioning cylinder 317, as the arc plate 314 moves between the two baffles 708, the space between the two baffles 708 is then under suction, one end of the double-diameter inner tube 315 in the arc plate 314 is aligned with the outlet hole 309 in the fan arc plate 308, and the other end is in the angle formed between the two baffles 708, so that the corn seeds are guided to be sucked into the double-diameter inner tube 315, so as to adapt to different sizes of seeds, as the positioning cylinder 317 continues to rotate, the arc plate 314 is separated from the angle space formed by the two baffles 708, so that the suction force is lost, the front end of the double-diameter inner tube 315 is larger than the diameter of the corn seed, and the rear end is smaller than the diameter of the corn seed, so that the corn seed is adsorbed into the double-diameter inner tube 315, passes through the front end diameter of the double-diameter inner tube 315, and is adsorbed in the port in front of the rear end diameter, after the suction force is lost, the corn seed falls back to the front end of the double-diameter inner tube 315, and is blocked by the fan arc plate 308, the double-diameter inner tube 315 continues to move under the driving of the rotating positioning cylinder 317, and rotates to the lower side of the inner arc plate 603, the corn seed in the double-diameter inner tube 315 falls and falls into the discharge plate 305 through the discharge window 606, and is guided into the ditch in the field, so as to perform the seeding operation;

[0064] Fertilization: in the rotation of the positioning cylinder 317, the rotation of the material blocking arc plate 604 at one end of the arc plate 314 opens the feeding window 607 of the inner arc plate 603, and the fertilizer enters the space between the arc plate 314, the positioning cylinder 317 and the material blocking arc plate 604 through the feeding window 607, after the positioning cylinder 317 continues to rotate, the material blocking arc plate 604 at one end of the next arc plate 314 blocks the feeding window 607 of the inner arc plate 603, so as to complete the single fertilizer introduction, and the double-diameter inner tube 315 in the arc plate 314 passes through the feeding window 607, although a small amount of fertilizer enters the double-diameter inner tube 315, but the fertilizer is blocked by the corn seed and cannot enter the rear end diameter of the double-diameter inner tube 315, so as to affect the whole seed suction process, under the cooperation of the gravity and the continuous rotation of the positioning cylinder 317, the fertilizer slides down along the inner wall of the material blocking arc plate 604 and is guided out, and the fertilizer at the bottom of the inner wall of the inner arc plate 603 is pushed out of the inner arc plate 603 by the next arc plate 314, so that after the seed is guided out of the discharge plate 305, the fertilizer is guided out of the discharge window 606 and then guided out of the discharge plate 305, realizing precision seeding of the corn seed.
