Embodiment Construction
[0011] The invention comprises a sun gear, a front intermediate gear and a rear intermediate gear, a planting arm planetary wheel, a planet carrier, a planting arm and a seedling needle. The sun gear of the transmission part is fixed, the planet carrier rotates around the sun gear, the planetary gear of the planting arm meshes with the rear intermediate gear, the front intermediate gear meshes with the sun gear, and the rear intermediate gear and the front intermediate gear rotate around the same axis. The rotational speed of the planting arm planetary gear is determined by the transmission ratio between the planting arm planetary gear and the rear intermediate gear, the transmission ratio between the front intermediate gear and the sun gear, and the rotational speed of the planet carrier.
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 As shown, the circular-elliptic pitch...
