Arable crop cultivating device, has sheave bands with angle of inclination tilted to vertical level after opening upward and with side which is convex to base level, and arranged in driving direction with angle of incidence

摘要

The device has a parallelogram (4) with a high side stiffness arranged in twistably, interlacing freely and transition securely to a large extent. Sheave bands (3) with an angle of inclination are tilted to a vertical level after opening upward and with a side which is convex to a base level, and are arranged in a driving direction with an angle of incidence. The sheave bands are arranged in the parallelogram.
