AGRICULTURAL MACHINE AND APPARATUS FOR COMPACTING PLANT MATERIAL TO OBTAIN PRESSED BULK MATERIAL Russian patent published in 1998 - IPC

FIELD: agricultural engineering, in particular, equipment for compacting stalk plant material. SUBSTANCE: apparatus has two hollow rolls positioned in parallel one with another and urged for rotation in opposite directions, and device for supplying material to be compacted into space between rolls to their circumferential part at feeding side. Hollow rolls are provided with teeth elongated in axial direction and made in the form of connecting members. Compacting channels of teeth are oriented toward inner cavity of rolls. At least portions of compacting channels are narrowing in radial direction into inner cavity of rolls. Hollow rolls are mounted so as to provide engagement of teeth in the manner similar to that of gears. Connecting members are made elongated in radial direction and adapted for heating. Connecting members are positioned on two spaced coaxial flange bodies. Compacting channels are positioned between connecting members. Apparatus is further provided with housing embracing hollow rolls. Agricultural machine has movable frame carrying plant material picking device and driver's seat, drive unit with engine and mentioned apparatus. EFFECT: increased efficiency, provision for reliable compaction of plant material even upon prolonged service life and large amounts of processed material per unit of time, and reduced power consumption. 50 cl, 18 dwg
