The continuously variable reducer 2071 transmits the power to the fertilizer discharge device 203 via a right-angle gearbox 2078. The seedling box reversing transmission box 703 distributes the power to each planting transmission box of the seedling box 4 via the seedling box transmission shaft 704, driving the seedling transplanting mechanism 706 to complete the seedling transplanting operation.

[0127] In this embodiment, the transplanting mechanism 706 includes a planting transmission box 705, a seedling taker 7061, a planting arm 7062, a seedling pusher 7063, and a seedling separating needle 7064. The seedling pusher 7063 and the seedling separating needle 7064 are fixed to the seedling taker 7061, the seedling taker 7061 is fixed to the planting arm 7062, and the planting arm 7062 is fixed to the planting transmission box 705. The planting transmission box 705 transmits the power from the chassis 1 to the planting arm 7062 to drive the seedling taker 7061 to rotate. The seedling taker 7061 cuts the seedlings through the seedling separating needle 7064 and inserts them into the mud surface. The seedling pusher 7063 causes the seedlings to detach from the seedling separating needle 7064 and plant them in the field.

[0128] The specific work process is as follows:

[0129] As the 6-row rice transplanter moves forward, it leaves wheel tracks in the field. Before applying fertilizer, the mud surface is leveled by the wheel track covering device 503.

[0130] The fertilizer discharge power mechanism 207 drives the cam and fertilizer cleaning scraper to rotate via the sprocket transmission mechanism 208, sending the fertilizer into the air-fertilizer mixing three-way pipe 2034. The air supply mechanism 204 evenly sends air into the air-fertilizer mixing three-way pipe 2034 to mix with the fertilizer. The mixed fertilizer is then applied into the fertilizer trench through the fertilizer conveying bend pipe 3, the first fertilizer guide pipe 5046, and the second fertilizer guide pipe 5074. At the same time, the first soil covering plate 5041 and the second soil covering plate 5071 can fill the fertilizer trench with soil during the forward movement, covering the fertilizer in the trench and preventing fertilizer loss due to runoff, volatilization, and other factors.

[0131] During the above process, the rotation of the fertilizer scraper enables the self-cleaning function of the fertilizer discharger 2033, and the air supply mechanism 204 can prevent fertilizer blockage.
