MILLING AND ROTARY SNOWPLOW Russian patent published in 2021 - IPC E01H5/09 

FIELD: municipal services.

SUBSTANCE: invention relates to the field of removing snow from roads or road surfaces. The milling-rotary snowplow contains a housing that is connected to the exhaust pipe. A milling cutter-rotor is installed in the center of the housing, and the right and left milling cutters are installed on the sides of the milling cutter-rotor. The cutter-rotor is made with the possibility of rotation and the formation of a snow flow through the discharge pipe. The right and left milling cutters are designed with the possibility to rotate at a speed lower than the speed of rotation of the milling cutter-rotor, and at the same time to rake snow and feed snow to the milling cutter-rotor, which has feeding blades located in the center, which are connected to the staggered ejection blades located on the sides. Besides, each feeding blade is connected to one ejection blade and is made with the possibility of feeding a portion of snow to this one ejection blade, which is made with the possibility of ejecting snow into the exhaust pipe.

EFFECT: creation of a snowplow with reduced energy consumption and increased productivity by eliminating the release of part of the snow through the cutter-rotor in front of the snowplow.
