| 简介 |
The machine has a frame and a roller including a tube mounted for rotation about an axis (XX). Another frame is connected to the former frame, and a wheel (5) includes a rim mounted for rotation about another axis (YY). The roller includes a covering (42) around the tube, where a pitch (L-P4) of transverse repeat of a pattern element (44) of the roller and a pitch (L-P5) of transverse repeat of a pattern element (54) of the wheel are equal to 10 percent. The elements define ribs (45, 55) so that the repetition and height of the ribs form parallel and equidistant furrows (11) in the earth (10). |
