The present invention relates to a combine knife and, more specifically, to a combine knife, which can prevent the bottom of rice from being cut long during a change of direction of a combine by positioning a split guide piece between dividing frames. The combine knife includes: a lower cutting support member which is fixed to dividing frames of the combine and has the front with a plurality of lower cutting blades and a split guide piece; two upper cutting members which is arranged on both sides of an upper part of the lower cutting member to reciprocate from left to right as much as a predetermined distance with the split guide piece arranged therebetween, and which has the front with a plurality of upper cutting blades coupled thereto; and a cutting blade fixing device which causes the upper cutting blades to be in close contact with the lower cutting blades, wherein the split guide piece is arranged to be eccentric to one side by being moved to a direction as much as a predetermined distance from the center of the lower cutting member so as to be positioned between the dividing frames, and wherein one of the two upper cutting members is formed to be longer than the other as much as the moved distance of the split guide piece. |
