A DEVICE THAT COPIES THE CUTTBAR HEADER FOR HARVESTING SOYBEANS
The article considers a variant of the patented design of the copying device of the cutterbar header for harvesting soybeans. The device contains a cutting machine mounted on a flexible finger bar. The finger bar is connected to the top of the header body with the help of an elastic band and longitudinal plates. At the bottom, under the cutting machine, along its entire width, there are support runners made of spring steel in the form of a leaf spring. The support runners have a front up-curved ski-like end fixed under the finger of the cutting machine. The up-curved ski-like end follows the lower contour of the cutting device's finger. The rear end of the support runners, also curved up in an Archimedean spiral, is attached to the header body. The longitudinal plate of the elastic band is made of spring steel with the convex side up along the Nicomed Conchoid, obtained by increasing the radius-vector of each point of this curve by the same segment. The quality of soybean harvesting is increased by improving the copying of the field topography and avoiding soil unloading in front of the support runners.
