the proposed technical solution relates to the field of road engineering, in particular to the design of snow removal equipment having rotary working bodies.

Snow removal equipment with a blade ensures cleaning of the roadway with the formation of snow shafts on the sidelines (bulldozers or other machines with dumps). Snow removal without the formation of snow deposits in the form of shafts is carried out with help, and rotary snow blowers. The rotary auger and milling rotor snowplows that are in operation are bulky (for example, KO-605, DE-210B-1M, KO-816, DE-220A, etc.) and are designed for snow removal on large areas (runways, access roads airfields, main roads, etc.) The existing screw-rotor and milling-rotor snowplows based on wheeled tractors do not provide snow cleaning from roadsides, slopes, roadsides behind a breaker bar and sidewalks. Currently, cleaning is carried out by small-sized self-propelled snow-cleaning rotors, and in Russia, mainly by hand, which is ineffective and inefficient, especially for remote sections of roads. The executive bodies of the milling and rotary snow blowers installed on the manipulator of a combined road machine based on a car chassis are capable of extending beyond the roadway and cleaning snow from roadsides, slopes, roadsides behind a chimney beam and sidewalks.

Known, similar in design and purpose, the executive bodies of the milling and rotary snow blowers KO-816, KO-816-1, milling snow loaders KO-207, KO-207-2 manufactured by SEVDORMASH Severodvinsk, as well as the working body of the rotary snow blower patent RU 2089703 , cl. E 01 And 5/09, publ. 09/10/97. etc. can not be used as sliding out of gauge combined road vehicles and other road vehicles, as they have large overall dimensions, large mass and the absence of fastening elements to the boom.

Known working body of the snow blower, consisting of counter-helical helical milling cutters, composed of sections of blades separated by cutting discs, rigidly attached to these disks.

The disadvantage of this design is the lack of blades for supplying snow mass to the thrower, which reduces the efficiency of the snow blower. fixed on the outside of two rings covering the shaft and

connected to it by knitting needles.

The disadvantage of this design is the lack of a cutting tool in the area of the blades, which leads to increased energy consumption of the working body.

Closest to the claimed technical solution is the working body of the rotary snow blower patent RU 2089703, ut. E 01 N 5/09, publ. 10.09. In this working body of the rotary snow blower, in front of the loading window, there are blades for supplying snow mass to the thrower, fixed between the inner and outer parts of the annular cutting disc at an angle to the radius of the disk, providing optimal conditions for supplying snow mass to the thrower.

The disadvantage of this design is the violation of the optimal angle of snow cutting (25 ° ... 30) with blades, which leads to an increase in snow cutting forces and energy consumption of the working body.

The objective of this technical solution is to eliminate these shortcomings and create a sliding outside the roadway, a quick-detachable, small-sized executive body of a milling and snowplow having the ability, as part of a combined road machine based on a car chassis or other road machine, to effectively clean snow from roadsides, slopes, roadside canvases behind a chimney beam, sidewalks and, in addition, in the transport position set in the space between driver’s bina and equipment located on the frame of the car chassis (body, tank, etc.).

The task is solved by creating the Executive body of the milling and rotary snow blower with a reduced width of the snow, while maintaining a high-performance thrower throwing snow, which can significantly reduce the size and weight of the Executive body.

The volumetric performance of the executive body of the milling rotor snow plow depending on the width of the snow and speed can be expressed as follows

 L h

where Q is the volumetric productivity of the executive body, V is the speed of movement, L is the width of the snow, h is the height of the snow cover.

Reducing the snow capture width L of the executive body in the presence of a snow throwing thrower with a capacity Q allows snow removal at a speed V increased in proportion to the decrease in snow capture width L, which ultimately maintains high performance of the executive body.

The executive body of the milling and rotary snow blower is equipped with a special bracket with mounting holes, designed to be attached to the boom.

Small overall dimensions and weight, the presence of a bracket with mounting holes allow you to use the actuator as a retractable outside the roadway, provide quick-release, as well as the ability to install it in the transport

LROY / OOu position in the space between the driver's cab and equipment

located on the frame of the car chassis (body, tank, etc.).

The executive body of the milling and rotary snow blower contains a housing with a loading window and a feeder installed in the housing, made in the form of blades of helical mills of the counter-winding. On the blades of screw mills from the side of the loading window, blades for supplying snow mass to the thrower are installed, the outer edge of the blades being offset to the center of the feeder shaft relative to the cutting edge of the blades of the screw mills.

The displacement of the blades to the center of the feeder shaft relative to the cutting edge of the blades of the screw cutters allows the snow to be cut in the area where the blades are located by screw cutters, in addition, the blades feed already cut snow into the loading window, which reduces the energy consumption of the actuator and increases the efficiency of snow supply to the loading window.

The executive body of the milling rotary snow blower consists of a housing 1 with a loading window 4, behind which there is a snow thrower 5.

A feeder 7 is mounted in the housing on a shaft, of which screw milling cutters 2 with counter winding are fixed. Snow feed blades are fixed on the milling cutters of the feeder 6. A snow splitter 3 is installed between the milling cutters of the feeder 3. The boom mounting bracket is located behind the snow thrower 8. The shaft of the snow thrower and the feeder shaft are rotated by the drive 9.

The Executive body of the milling and rotary snow blower operates as follows.

When driving on the roadway, the drive 9 rotates the shafts of the feeder 7 and the snow thrower 5, while the mills of the counter winding 2 of the feeder with the blades 6 fixed on them begin to rotate. The snow mass is developed by the milling cutters and fed to the loading window 4. The snow mass between the mills loosened by divider 3. The blades 6 move the developed snow into the loading window 4 of the snow thrower. The thrower throws snow away from the roadway.
