The utility model belongs to the technical field of mechanical structures, and particularly relates to a soybean separation header which comprises a header
body frame, the bottom of the header
body frame is a header bottom plate comprising a rear side short plate and a front side extension plate, a
cutting assembly is installed on the front side of the header bottom plate, soil screening holes arranged in a matrix mode are formed in the plate face, and a flashboard mechanism capable of sliding synchronously is arranged at the bottom. The opening and closing states of the screen holes are controlled through the adjusting
handle. The reinforcing rib structure at the bottom of the header bottom plate is divided into independent
trepanning areas, the guide sliding grooves and the
spring steel plates are matched to ensure that the flashboards are tightly attached, and the adjacent flashboards are linked through the screw assemblies. Dividers are installed on the two sides of the device to improve the
terrain adaptability. The harvester has the advantages that
silt is separated in real time through the
sieve holes, the grain cleanliness is improved, rapid switching of harvesting
modes of crops such as beans and rice and wheat is achieved through flashboard adjustment, the structural strength is enhanced through
modular design, maintenance is simplified, precise and stable operation is guaranteed through screw transmission, labor intensity and production cost are effectively reduced, and high efficiency and universality are achieved.
