FIELD: agricultural machinery industry.
SUBSTANCE: the group of inventions relates to a chopping rotor and a cutting and separating device with such a rotor. The chopping rotor 110 for the cutting and separating device has an inlet 113 and an outlet 115, respectively, made at the first end section 112 and the second end section 114 of the chopping rotor 110. In addition, on the section 116 of the pressure housing of the chopping rotor 110, there are many cutting holes 120 that penetrate through the section 116 of the pressure housing from the inner wall 117 to the outer wall 118. Moreover, on the inner wall 117 each cutting hole 120 has a cutting edge 122a of the hole facing the outlet 115 and a retracting edge 122b of the hole facing the inlet 113. Between the cutting edge 122a of the hole and the retracting edge 122b of the hole, there is a supply channel 100 lowered relative to the inner wall 117.
EFFECT: the chopping rotor and a cutting and separating device with such a rotor provide an increase in productivity.
