SNAPPING ROLL UNIT FOR MAIZE HEADER

摘要

A new system header for maize harvesting supplied with snapping units, the two snapping rolls of which rotating in opposite directions and with different rotational speeds, simultaneously with the cob snapping crushes the maize stalk. The invention is a new system maize header with the snapping units (2) comprising of two snapping rolls (8, 9) with rotationally interlocked toothed blades (18, 19), rotating in opposite directions and with different rotational speeds, having the task of cutting and crushing the maize stalk (15) while completing in full the cob snapping function. During operation as a result of the snapping rolls (8, 9) rotating in opposite directions and with different rotational speeds the toothed blades (18, 19) move towards each other and grip the stalk (15). Based on the operation claimed above the two snapping rolls (8, 9) of the maize header (1) subject of the invention, built into the snapping unit (2) perform the cutting and crushing of the maize stalk (15) while completing in full the tasks in the cob snapping function.
