Summary:The invention discloses a cutter and a rice and wheat combined harvester, and belongs to the field of harvesting equipment. According to the cutter disclosed by the invention, a driving wheel and a driven wheel are accommodated in a cavity in a housing of a transmission mechanism; the driving wheel is in non-uniform-velocity transmission cooperation with the driven wheel, so that a moving knife ona cutting knife assemble is in non-uniform-velocity reciprocating motion relative to each fixed knife; in the working process of the cutter, the relative velocity between each fixed knife and the corresponding moving knife is in periodical variation; when the moving knives are under an effective cutting stroke, the relative velocity between the fixed knives and the moving knives is large, so thatthe cutter has good cutting properties; and when the moving knives are under a null steering stroke, the relative velocity between the fixed knives and the moving knives is small, so that the instantaneous acceleration of the
