MOWER WITH BEATER-SCREW CONDITIONER Russian patent published in 2020 - IPC A01D34/64 

FIELD: machine building.

SUBSTANCE: mower with beater-screw conditioner comprises bearing bar 1 with rotating towards each other disks 2. On disks 2 are hingedly fixed blades 3 and rigidly fixed vertically on disks 2 non-detachable drums 4, 5 in form of truncated cones. All drums 4, 5 are made identical in height and rigidly fixed on pairwise rotating disks 2, alternating each other. First drum 4 on the right in the movement direction of the mower is equipped with a screw of the left direction of rotation consisting of plates 6, 7 of curvilinear shape. Latter are rigidly installed on its external surface at an acute angle relative to direction and plane of rotation. Outer edges of plates 6, 7 have variable radius decreasing in direction of their rotation and not exceeding radius of cutting edge formed by ends of hinged knives 3 of disks 2. First drum 5 in the upper part is equipped with hinged L-shaped beaters containing impact bars 8, crosspieces 9 and stops 10. L-shaped beaters in upper part of drums 5 are located diametrically opposite to their vertical axes, perpendicular to knives 3 of disks 2 and are pivotally attached by radial projections of bands 11 behind webs 9 to side surface of top part of truncated drums 5. Stops of 10 L-shaped beaters are designed to exclude possibility of their jump-out from radial projections of bands 11. Impact rods 8 of beaters on each drum 5 can be installed horizontally in one plane or different.

EFFECT: invention makes it possible to improve feed of chamfered mass to the zone of beating treatment, to increase quality of injuries of plant stems and to reduce field losses.
