(1) principle

Floating type paddy field harvester for both rice and wheat is the tractor that drives with standing header reaping apparatus 1 and two-wheel or single wheel, link together by four-

bar mechanism

3,4 and link 7, the ceding of Taiwan 1 acts on the face of field, thereby can guarantee the cutting height unanimity by its lower plane during work, tractor driving wheel 8 is along with soil soft or hard difference, the degree of depth that freely is absorbed in the soil is also different, and like this, the ceding of Taiwan 1 that is positioned at front end is because the four-

bar mechanism

3 and 4 the effect that is connected, pushing away by 8 and to advance, finishing cutting operation.Four-

bar mechanism

3 and 4 is respectively by rod piece A B(A ' B ') and CD(C ' D ') form, A, C fulcrum are positioned at header 1, B, D fulcrum are arranged in the link 7 fastening with tractor, like this, when wheel 8 or the ceding of Taiwan 1 because subsoil or field face when causing that just it fluctuates up and down, just can the automatic profiling operation, the traction drives unit that wheel 8 produces advances, thereby can adopt the iron tyre of original tractor just can supporting harvester operation.For the two-wheel structure, its wheelspan L, Ying Yixiao is advisable, when avoiding iron tyre to sink rotation with on soil be pressed in the straw that does not cut the district.

(2) soil suitability

To holding up the line unit, floating of the ceding of Taiwan 1, rely on four-

bar mechanism
