[0027] The following describes a single use of this utility model with reference to the accompanying drawings:

[0028] First, the millet to be sown is loaded into the storage box 18. Then, the loosening motor 7 is started, which drives the loosening shaft 8 to rotate, thereby driving the loosening cutter head 9 and the loosening blades 10 to rotate.

[0029] When the soil loosening motor 7 is started, the power output rod of the control electric push rod 4 retracts downward, driving the slider to move downward along the slide rail. As the slider moves downward, the adapter ear plate 5 and the forward support arm 6 also move downward synchronously, eventually driving the soil loosening mechanism at the front end of the forward support arm 6 to descend until the soil loosening blade 10 is screwed into the soil to the set depth.

[0030] Once the loosening blade 10 has rotated into the soil to the set depth, the soil is loosened by the rotating loosening blade 10. Then, the electric walking wheels 2 are started to make the seeder follow the set route.

[0031] After the seeder starts moving forward, the height adjustment motor 13 of the furrowing and pressing wheel starts, driving the lead screw 14 to rotate. The rotation of the lead screw 14 is synchronously converted into the downward movement of the lead screw slide 15. In turn, the downward movement of the lead screw slide 15 drives the furrowing and pressing wheel rotation drive motor 12 and the furrowing and pressing wheel 11 to descend synchronously until the furrowing and pressing wheel 11 presses into the set depth of the loosened soil. At this time, the furrowing and pressing wheel rotation drive motor 12 does not start. As the seeder moves forward, the furrowing and pressing wheel 11, which has pressed into the set depth of the loosened soil, will complete the furrowing of the soil and form ridges.

[0032] As the seeder moves forward, when the pecking head 27 first enters the furrow area, the pecking cylinder 26 is activated, driving the piston rod to extend downward, which in turn drives the pecking head 27 to descend until the pecking head 27 forms a pecking hole of a set depth at the bottom of the furrow.

[0033] Once the pits are formed at the bottom of the furrow, the piston rod of the pit-pecking cylinder 26 retracts and resets, causing the pit-pecking pressure head 27 to rise and reset. Subsequently, the electric flap-type quantitative discharge valve at the discharge port at the bottom of the storage box 18 is activated, causing the millet in the storage box 18 to fall quantitatively through the discharge port at the bottom of the storage box 18 into the receiving funnel 19 below, and then through the discharge port of the receiving funnel 19 and the inlet opening 24 of the sealing ring sleeve 23 into one of the empty discharge holes 22.

[0034] When the millet falls into the empty discharge hole 22, the seeding motor 21 is started, which drives the seeding wheel 20 to rotate. The discharge hole 22 carrying the millet will enter the coverage area of ​​the sealing ring 23 as the seeding wheel 20 rotates, so the millet will not fall out of the discharge hole 22. When the discharge hole 22 carrying the millet moves to coincide with the discharge opening 25 of the sealing ring 23, the discharge hole 22 is no longer covered by the sealing ring 23. Under the action of gravity, the millet in the discharge hole 22 will automatically fall into the pecking pit at the bottom of the furrow below.

[0035] As the seeder moves forward, when the covering plate 3 passes the sown furrow, it pushes the soil on both sides of the furrow into the furrow, thus achieving soil covering and leveling of the soil surface.

[0036] During the movement of the seeder, loosening the soil, opening furrows, pecking holes, sowing seeds, and covering the soil are a continuous and repeated process. The amount of seeds sown each time is completely limited by the volume of the seed drop hole 22, which ensures that the amount of millet sown in each hole is very precise and effectively eliminates the drawback of uneven millet sowing in traditional millet sowing.

[0037] After all millet sowing operations in a certain area are completed, the soil after covering with soil still has low compaction. In order to improve the compaction of the soil after covering with soil and optimize the germination environment of millet in the soil, it is advisable to compact the soil after covering with soil.

[0038] During soil compaction operations, the soil loosening mechanism, material storage mechanism, seed spreading mechanism, lifting and adjusting mechanism, and pit pecking mechanism are all in their initial positions and are not activated; only the trenching and compaction mechanism is activated. First, start the electric walking wheels 2 to make the seeder travel along the set route during the sowing operation. Then, start the furrowing and soil compaction wheel height adjustment motor 13 to drive the lead screw 14 to rotate. The rotation of the lead screw 14 is synchronously converted into the downward movement of the lead screw slide plate 15. In turn, the downward movement of the lead screw slide plate 15 drives the furrowing and soil compaction wheel rotation drive motor 12 and the furrowing and soil compaction wheel 11 to descend synchronously until the furrowing and soil compaction wheel 11 is pressed into the soil after covering with soil to an appropriate depth. This depth only needs to meet the soil compaction requirements. At the same time, start the furrowing and soil compaction wheel rotation drive motor 12 to drive the furrowing and soil compaction wheel 11 to rotate. The speed and direction of the furrowing and soil compaction wheel 11 are exactly the same as those of the electric walking wheels 2. During the movement of the seeder, the downward rolling furrowing and soil compaction wheel 11 compacts the soil after covering with soil until the soil compaction operation in the entire area is completed.

[0039] The solutions in the embodiments are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications that do not depart from the scope of protection of this utility model are included in the scope of protection of this utility model.
