The structures of the scoop wheel seeder 3 and the groove fertilizer feeder 4 are prior art.

[0028] The above-mentioned seeding and fertilizing machine is installed with a first transmission box 7 for transmitting the movement between the rotating shaft of the walking wheel 5 and the flexible shaft 9; and a second transmission box 8 for transmitting the movement between the rotating shaft of the grooved fertilizer feeder 4 and the flexible shaft 9, so that the rotation of the walking wheel can be transmitted to the flexible shaft 9 through the first transmission box 7, and the rotation of the flexible shaft 9 can be transmitted to the rotating shaft of the grooved fertilizer feeder 4 through the second transmission box 8, thereby performing fertilization operations.

[0029] Specifically, the first transmission box 7 includes a first base plate 701, a first cover, a worm wheel 704 rotatably mounted on the first base plate 701, two bearing seats 702 fixedly connected to the first base plate 701, and a worm 703 rotatably mounted between the two bearing seats 702 and meshing with the worm wheel 704; a first hexagonal hole 705 for connecting with the rotating shaft of the walking wheel 5 is provided at the center of the worm wheel 704; a first square hole 706 for matching with the square shaft 901 of the flexible shaft 9 is provided at the center of the worm 703; a limiting column 707 is fixedly connected in the first square hole 706; a first threaded hole 708 for threadingly connecting with the sleeve plug 903 at the end of the sleeve 902 wrapped by the flexible shaft 9 is provided on the bearing seat 702 for installing the flexible shaft 9.
