METHOD OF COMBINE HARVESTING OF MUSTARD SEED CROPS AT CULTIVATION IN RICE CHECKS AND THRESHING DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: agriculture.;SUBSTANCE: group of inventions relates to agriculture. The method of harvesting mustard crops involves mowing around the perimetre of technological roads, along the irrigation channel and long side of a rice check. In the phase of milky-wax ripeness of mustard mowing is carried out with the width equal to width of the harvester header. Between these narrow swaths the wide unmown bands are left which are equal to the width of several multiples of the working width of the header. Simultaneously with the mowing of narrow swaths the mustard threshing is carried out for technical purposes. Upon reaching complete ripeness of mustard seeds in wide bands mowing and threshing of mustard seeds is carried out for seed-production purposes. The threshing device comprises a bar-slatted deck and a drum. The drum is made in the form of the drive shaft, wheels, the undervane elements and vanes made of elastic material. Each vane in the cross section has a shape of an equilateral trapezoid. The vane is mounted with its broad base in the transition element. The transition element is attached by fastening means to the wheels and has in the cross section the C-shaped form. The ends of the elastic vanes in transition elements are fixed with tightening devices. The middle parts of the vanes in the transition elements are fixed with retainers.;EFFECT: inventions provide obtaining of mustard seed material with high germination energy and without mechanical damage and microtraumas.;2 cl, 7 dwg
