Mobile rotary press for baling e.g. silage, straw or hay

摘要

The press comprises a small front pressing chamber and a large rear pressing chamber. The press has upper and lower rotating systems which connect or separate the two chambers. The upper system comprises two large pressing rollers (1) which rotate on a frame (6) which itself rotates about its middle point. The rollers are driven via the drive shaft (5) of the frame. The shaft rotates in the opposite direction to the rollers. A toothed wheel (4) on the drive shaft is larger than toothed wheels (2,3) on each of the roller shafts (43,44). The frame has two notches (39,40) on its edge and forms a slider (41). A cylinder (38) stops rotation of the slide, and also of the whole rotating system, when it is inserted in one of the notches. The cylinder has a spring (42) to keep it in the notch.
