The belt transmission assembly 17 drives the first gear 18 to rotate, thereby driving the second gear 19 to rotate, and the two first fertilizer pipes 906 rotate symmetrically, thereby synchronously adjusting the angles of the two first fertilizer pipes 906 so that the first fertilizer pipes 906 can be aligned with the roots of the crops. The electric telescopic column 7 is telescopic to drive the first mobile frame 801 and the two first pistons 802 to move up and down. When the first piston 802 moves down and extends into the liquid pumping cylinder 901, the first sealing plate 806 and the second sealing plate 904 are automatically opened.
