DEVICE FOR DISTRIBUTING GRAIN AND THE EAR PILE OF A COMBINE HARVESTER Russian patent published in 2021 - IPC A01D41/12 A01F12/44 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering and can be used in combine harvesters for the distribution of grain and ear pile coming after cleaning the combine. The device contains an autonomous device to finish threshing with a rotor and a deck located in its case mounted on a grain elevator. The device is equipped with a distribution screw having blades mounted at the end of the screw tape. The screw is placed along the axis of the rotor, connected through the neck to the housing of the threshing device and is pivotally fixed on one side by means of a flange bearing support on the frame of the threshing machine, and on the other side - on the bearing support of the housing of the threshing device. The screw with blades is enclosed in a closed casing consisting of a pipe and a distributor housing. The position of the distributor housing is determined by the middle of the width of the wind/screen separator. The shape of the distributor body is designed to ensure the unloading and uniform distribution of grain and ear pile along the width of the wind/screen separator at various physical properties of the harvested crops and the conditions of the agricultural background.

EFFECT: use of the invention increases the productivity of the combine harvester, reduces grain losses and improves the uniformity of the distribution of grain and the ear pile over the width of the wind/screen separator, regardless of the various physical properties of the harvested crops and the state of the agricultural background.
