[0032] In another embodiment provided by the present invention, a servo electric cylinder 24 is fixed inside the frame 2, and a brush plate 23 is fixed to the output end of the servo electric cylinder 24. The servo electric cylinder 24 drives the brush plate 23 to move downward, so that the bristles of the brush plate 23 extend to the inside of the seedling tray 3, and then the bristles of the brush plate 23 can brush the soil in the seedling tray 3 to level it. A water spray assembly 25 is fixed inside the frame 2, and the water spray assembly 25 is located on the top of the support platform 1. The water spray assembly 25 is connected to the water pump through a hose, so that the water spray assembly 25 can spray water to the inside of the seedling tray 3, so that the inside of the seedling tray 3 can be replenished with water.

[0033] In another embodiment provided by the present invention, the walking mechanism 29 includes a motor 30 fixed to the frame 2, the frame 2 has a motor 30 on both sides, the output shaft of the motor 30 is fixed with a gear 32, the side wall of the support platform 1 is fixed with a rack 28, the support platform 1 has a rack 28 on both sides, the gear 32 is meshed with the rack 28, the gear 32 is located at the bottom of the rack 28, when the motor 30 drives the gear 32 to rotate, the gear 32 drives the frame 2 to move by meshing with the rack 28, the bottom outer wall of the frame 2 is rotatably connected with a roller 31, the side wall of the support platform 1 is fixed with a guide rail 27, and the roller 31 is rollingly connected with the guide rail 27. The roller 31 is rollingly connected with the guide rail 27, so that the friction force on the frame 2 during movement is reduced, and the frame 2 can move linearly along the guide rail 27; the top outer wall of the support platform 1 is fixed with a limiting component 4, and the limiting component 4 is adapted to the seedling tray 3. The limiting component 4 has a blocking effect on the seedling tray 3 to prevent the seedling tray 3 from moving on the support platform 1; the side wall of the support platform 1 is fixed with a limiting component 2 33, and the limiting component 2 33 is adapted to the frame 2. The limiting component 2 33 can block the frame 2 to prevent the frame 2 from separating from the support platform 1.

[0034] Working principle: First, multiple seedling trays 3 are arranged closely on the support platform 1, and the seedling trays 3 at both ends of the support platform 1 are in contact with the limit assembly 1, then the frame 2 is located at the left end of the support platform 1, and then soil is added to the soil bin 7, and then the motor 1 30 drives the gear 32 to rotate, so that the gear 32 drives the frame 2 to move to the right through the engagement with the rack 28, and at the same time, the motor 2 34 drives the shaft 11 to rotate, so that the shaft 11 drives the gear 32 to move to the right. The material-push rod 12 is driven to move, so that the material-push rod 12 pushes the soil inside the soil bin 7 out from the discharge port 14, so as to achieve the effect of evenly filling the soil into the seedling tray 3. When filling into the seedling tray 3, the servo electric cylinder 24 drives the brush plate 23 to move downward, so that the bristles of the brush plate 23 extend into the interior of the seedling tray 3, and then the bristles of the brush plate 23 can brush the soil inside the seedling tray 3 flat. After the soil inside the seedling tray 3 is filled, the frame 2 is returned to the support The left side of the support platform 1 is used to fill the rice seeds into the seed bin 8, and then the frame 2 is moved to the right along the support platform 1, and the motor 2 is used to drive the shaft 11 to rotate. When the shaft 11 rotates, it drives the active pulley 9 to rotate. The rotation of the active pulley 9 drives the driven pulley 10 and the shaft 20 to rotate. The shaft 20 drives the connecting plate 21 to perform a circular motion, so that the extrusion wheel 22 on the connecting plate 21 intermittently squeezes the screen frame 15, causing the screen frame 15 to vibrate, thereby causing the rice seeds inside the seed bin 8 to fall out of the screen plate 16 through the vibration, so that the rice seeds fall into the inside of the seedling tray 3, and the effect of automatically sowing seeds into the inside of the seedling tray 3 is achieved. While sowing seeds inside the seedling tray 3, the discharge port 14 of the soil bin 7 on the left side of the seed bin 8 continuously discharges soil, so that the soil covers the rice seeds. At the same time, the water spraying component 25 can spray water to the inside of the seedling tray 3, so that the inside of the seedling tray 3 can be replenished with water.

[0035] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
