[0021] It should be noted that: crop seeds can be placed in the feeding tank 1. Under the action of gravity, the seeds fall onto the feeding component 5 inside the shell 3. By rotating the feeding component 5, the seeds can be rotated downwards and fall into the ditch through the discharge pipe 4 for sowing. This can push the device to move, achieving uniform sowing. During the rotation of the feeding component 5, it can drive the reciprocating component 6 to rotate. The reciprocating component 6 drives the drive component 7 to move up and down. The up and down reciprocating motion of the drive component 7 can drive the two soil covering components 9 to move back and forth within a certain angle. The reciprocating rotation of the two soil covering components 9 can push the soil accumulated on both sides of the ditch when it was dug back into the ditch to cover the newly sown seeds. This achieves soil covering of seeds at the same time as sowing, which is more convenient.

[0022] In a preferred embodiment, the feeding assembly 5 includes a motor 501, a feeding roller 502 connected to one end of the output shaft of the motor 501, and a plurality of equally spaced partitions 503 installed on the outer wall of the feeding roller 502.

[0023] It should be noted that the seeds can fall onto the feeding roller 502. The motor 501 drives the feeding roller 502 to rotate, which can rotate the seeds downward and drop them into the ditch through the discharge pipe 4 for sowing.

[0024] In a preferred embodiment, the reciprocating assembly 6 includes a disk 601, a positioning rod 602 mounted on an eccentric position on one side of the outer wall of the disk 601, and a traction rod 603 rotatably connected to the outer wall of the positioning rod 602.

[0025] It should be noted that the rotation of the feeding roller 502 can drive the disc 601 to rotate, and the rotation of the disc 601 can drive the drive assembly 7 to move up and down reciprocally through the traction rod 603.

[0026] In a preferred embodiment, the drive assembly 7 includes an L-shaped plate 701, a fixing rod 702 mounted on one end of the bottom outer wall of the L-shaped plate 701, a double-sided rack 703 mounted on one end of the top outer wall of the L-shaped plate 701, and a limiting ring 704 mounted on one side outer wall of the L-shaped plate 701.

[0027] It should be noted that the L-shaped plate 701 can reciprocate up and down, thereby driving the double-sided rack 703 to reciprocate up and down.

[0028] In a preferred embodiment, the soil covering assembly 9 includes a rotating rod 901, a gear 902 mounted on the outer wall of the rotating rod 901, a mounting plate 903 mounted on the outer wall of the rotating rod 901, and a soil covering plate 904 mounted on the bottom of the mounting plate 903.

[0029] It should be noted that the double-sided rack 703 reciprocates up and down, which can drive the two gears 902 to rotate relative to each other or in opposite directions, thereby driving the two soil covering plates 904 to move in an arc, approaching or separating from each other. When the two soil covering plates 904 approach each other, they can push the soil accumulated on both sides of the trench back into the trench.

[0030] In a preferred embodiment, the double-sided rack 703 has a toothed structure on both sides.

[0031] It should be noted that the reciprocating motion of the double-sided rack 703 can drive the rotation of the two gears 902.

[0032] Working principle: Crop seeds can be placed in the feeding tank 1. Under the action of gravity, the seeds fall onto the feeding roller 502 inside the shell 3. The motor 501 drives the feeding roller 502 to rotate, which can rotate the seeds downward and drop them into the ditch through the discharge pipe 4 for sowing. The device can be moved to achieve uniform sowing. The rotation of the feeding roller 502 can drive the disc 601 to rotate. The rotation of the disc 601 can drive the L-shaped plate 701 to move up and down through the traction rod 603, which in turn drives the double-sided rack 703 to move up and down. The up and down movement of the double-sided rack 703 can drive the two gears 902 to rotate relative to each other or in opposite directions, which in turn drives the two covering plates 904 to move in an arc, approaching or separating from each other. When the two covering plates 904 approach each other, they can push the soil accumulated on both sides of the ditch back into the ditch to cover the newly sown seeds. This realizes the simultaneous sowing and covering of seeds, which is more convenient.
