Foldable cutting device and harvester with same

The utility model relates to the technical field of hybrid wheat breeding equipment, in particular to a foldable cutting device and a harvester with the same. Driven cutters are symmetrically mountedon the left side and the right side of a main cutter of the cutting device correspondingly. The cutting transmission mechanism is connected with the main cutter, a cutting transmission mechanism is installed between the main cutter and each driven cutter, and the cutting transmission mechanisms are used for driving the main cutter to do horizontal cutting motion and driving the driven cutters to do synchronous cutting motion along with the main cutter; a folding driving assembly is installed between the main cutter and each driven cutter and used for driving each driven cutter to be unfolded or folded on the two sides of the vehicle body. The harvester comprises the foldable cutting device. The cutting device can carry out horizontal cutting motion on plant ears, and has folding and unfolding multi-mode working an
