A power mechanism for driving the conversion between the grooved idler 3 and the horizontal idler 4 is also provided. The grooved idler 3 and the horizontal idler 4 are arranged on one rotating shaft 2. When discharging is not required, the horizontal idler 4 is converted into the grooved idler 3, and the tape is converted from a flat discharging state to a grooved conveying state, so as to support the tape below the plow head and enable the material to pass smoothly, improving the stability.

[0029] Specifically, the power mechanism includes a swing arm 8, a connecting rod 9, a driving arm A10 and a driving arm B11.
