However, for small-area or stepped planting, mechanical planting cannot be used, and manual planting according to experience is needed, so how to standardize planting and make crops grow well is a problem to be solved.

[0004] For crop planting, since the planting area of crops is small, in some cases, manual seeding or drill seeding is used for seeding. Drill seeding needs manual operation of a seeding machine for seeding, and since the seed drop cannot be controlled in the whole process, seed waste occurs during drill seeding row changing. In addition, some seeds need to be planted with a spacing during planting, and the point seeding method is used for planting crops, so the application range of drill seeding for crop seeding is reduced. How to control the seed drop to make drill seeding adapt to different spacing of crop planting is a problem to be solved.

[0028] Use method is explained in detail:

[0029] The device is connected with the seeding machine, and then the sliding limiting piece 12 is installed on the seeding machine. The sliding limiting piece 12 needs to be guaranteed to be located outside the connecting part of the fixed piece 10 and the connecting rod 9, so that when the artificial control outer cutter shell 1 moves downward, the connecting rod 9 can rotate around the through hole 11, and the conical cavity 5 at the bottom of the outer cutter shell 1 is opened. Ensure that the seeds can normally fall. Because the cutter head part of the outer cutter shell 1 needs to be inserted into the soil during seeding, the inner seeding cutter 2 moves together with the outer cutter shell 1 during this process, that is, the inner seeding cutter 2 and the outer cutter shell 1 are fixed on the same rod of the seeding machine, and for the whole seeding machine, the rod where the inner seeding cutter 2 and the outer cutter shell 1 are located can rotate. During the rotating process (the process of inserting the inner seeding cutter 2 into the soil), the outer cutter shell 1 can be inserted into the soil by mechanical control or artificial foot stepping on the support 13 at the top of the outer cutter shell 1.

And if point planting of crops is needed during seeding, the control piece 4 can also be controlled to make the inner seeding cutter 2 move up and down in the outer cutter shell 1 continuously to complete the point planting operation. After each row of seeds is planted, the inner seeding cutter 2 is controlled to move downward, so that the discharge port 3 is blocked due to the action of the conical cavity 5, reducing the waste of seeds. The outer cutter shell 1 moves upward, so that the cutter retracts. During the retraction of the cutter, the sliding limiting piece 12 controls the rotation of the connecting rod 9, so that the outlet of the conical cavity 5 is blocked, avoiding the blockage of the conical cavity 5 when inserting into the soil next time.

[0031] As described above, the device controls the downward movement distance of the support 13 to control the depth of the cutter inserted into the soil, so that the cutter can complete the plowing of seeds with different depths. The device prevents the soil from blocking the seed outlet when the cutter is inserted into the soil through the protection piece 8, avoiding the situation that the seeds cannot normally fall. And the control piece 4 controls the upward and downward movement of the inner seeding cutter 2, so that the device can control the seeding of the seeds, and can complete the operations such as strip planting and point planting. And the device controls the spacing of the seeds during seeding by continuously controlling the upward and downward movement of the inner seeding cutter 2, so as to reasonably plan the planting of the seeds.
