FIELD: agriculture.SUBSTANCE: invention relates to agricultural machinery industry. The proposed truck combine for harvesting rough feed comprises a removable adapter, a feeding device having in its lower part the window with the transverse slides serving as splitters of lower ribbed reversing rollers, a grinding drum, a silage duct, a crawler truck, and a motor unit. In the rear part of the combine coaxially to its longitudinal axis a screw press is mounted, a loading hopper of which is covered on top with a continuous sheet formed in a longitudinal section along the Archimedean spiral in the polar coordinate system r=a·?, where r is the radius vector; ? is the angle of rotation; a is a helix pitch distance. Performance of the screw press 1.2 times exceeds the performance of the silage duct.EFFECT: invention reduces the cost of feeding the crushed mass of silage or hay to the place of pressing, reduces the harmful anthropogenic effect on soil from the harvester chassis.2 cl, 4 dwg |
