[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the described contents.

[0041] See also Figure 1The present application provides a tobacco seedling transplanter, comprising a walking platform 1, a pond-digging mechanism 2, a transplanting mechanism 3, and a seedling supply mechanism 4; a mounting rod 14 extending horizontally forward is provided on the front side of the walking platform 1, and a sleeve 15 is slidably connected to the mounting rod 14. It can be imagined that a screw is threadedly screwed on the sleeve 15, and the screw is tightened, and the lower end of the screw presses against the mounting rod 14, thereby effectively fixing the position of the sleeve 15, and the sleeve 15 is provided with a pond-digging mechanism 2; a transplanting mechanism 3 is provided in the middle of the walking platform 1, and a seedling supply mechanism 4 is provided above the transplanting mechanism 3; in this way, when performing tobacco seedling transplanting operations, the distance between the pond-digging mechanism 2 and the transplanting mechanism 3 can be changed by sliding the sleeve 15, thereby achieving the purpose of adjusting the distance between adjacent tobacco ponds, so as to improve the applicability of the transplanter.

[0042] The walking platform 1 is provided with an image recognition module 5 for detecting the position of the chimney on the land, and the image recognition module 5 is electrically connected to the walking platform 1 .

[0043] Working mode 1: The transplanter moves along the ridge through the walking platform 1, and first digs a pond through the pond-digging mechanism 2. When the transplanting mechanism 3 moves to the dug pond, the transplanting mechanism 3 transplants the tobacco seedlings into the pond, completing the tobacco seedling transplanting operation, realizing the mechanized and automated operation of tobacco seedling transplanting, improving the work efficiency of tobacco seedling transplanting, and reducing the labor intensity of farmers in tobacco seedling transplanting.

[0044] Working mode 2: When the transplanter moves to the position of the ridge to be transplanted through the walking platform 1, the transplanter first only performs pond digging operations. After the pond is dug, the seedling holes need to be exposed to the sun for several days to achieve the effect of disinfection and sterilization; after the pond is exposed to the sun, the transplanter moves to the position of the pond ridge, and the image recognition module 5 begins to recognize the contour of the pond, determine the planting position, control the walking platform 1 to move, and control the transplanting mechanism 3 and the seedling supply mechanism 4 to work, accurately plant the tobacco seedlings in the center of the pond, and fertilize and water them.

When the seedling dropping cup 45 moves to a position corresponding to the position of the seedling dropping hole 4301, the tobacco seedlings fall downward from the seedling dropping hole 4301 into the transplanting mechanism 3, and then are transplanted into the tobacco pond through the transplanting mechanism 3. When in use, the rotation speed of the seedling supply motor 42 can be adjusted to control the interval time for adjacent seedling dropping cups 45 to move to the seedling dropping hole 4301, thereby controlling the interval for dropping seedlings.
