MILLING-ROTARY SNOWPLOUGH Russian patent published in 2024 - IPC E01H5/00 

FIELD: removal of snow or ice from roads or road surfaces.

SUBSTANCE: invention relates to snow removal equipment, namely to milling-rotary snow ploughs. Milling-rotary snowplough comprises housing (1), which is connected to discharge branch pipe (2), opposite to which in the right part of the housing there is cutter-rotor (3), and in the left part of the body there is feed cutter (7). At that, the cutter-rotor is made with possibility of rotation at a speed higher than that of the feed cutter. Wherein said snowplough comprises power take-off shaft to transmit rotation via safety clutch to bevel gearbox (5) to reduce rotation speed to W1. At that, bevel gearbox is rigidly connected to housing and is made with possibility of rotation through elastic coupling (4) and right driven shaft of cutter-rotor with speed W1, bevel gearbox left driven shaft is configured to transmit rotation to planetary gearbox (6) sun gear. At that, planetary reduction gear carrier is made with possibility of rotation through shear safety rod of feed cutter with speed W2=W1/3:5. At the same time the sun gear of the conical reduction gear is rigidly connected to the housing of the conical reduction gear.

EFFECT: higher efficiency of snow removal.
