Anyone who’s after a heavy snowfall had to clear sidewalks, alleys, parks, school hockey pitches, knows how difficult this job is. And involuntarily thought: “that would be Here some gear!”. And really, why not mechanize the work? No sooner said than done. So there is a compact mechanical “the janitor”, a description which we offer today readers.
Rotary snow blower “Blizzard” is designed and manufactured by members of the design circle of the Penza regional station of young technicians L. Chaadayev, V. Ageev, S. Martynov. This mechanism is relatively simple and can be done in any school workshop where there welding machine, lathe machine, TV-6 and waste from steel sheet of thickness 2 mm.
The power plant is the machine — D-6 engine with the muffler, tank and control cable the throttle from a motorbike. The torque from the engine is transmitted to the chain sprocket Z = 18 fixed to the rotor shaft, made on the lathe centers with a single installation. As a blank we used the corresponding part of the burnt motor. A shaft seated in the housing 4 arranged in pairs ball bearing No. 80202 and fixed by steel clamping ring and the M6 bolts on the rotor housing. A special bracket gripping pressure ring serves for mounting the rotor housing to the frame.
The main working body of the machine — rotor — consists of a steel disc Ø 290 mm and a thickness of 2 mm, to which the first screws M6 is attached to the hub and then to the disk and the hub are welded clamps 5 blades, reinforced back ribs. When assembling the blower rotor shaft fixed nut M10 stop.
The rotor body is welded of steel, has a removable front wall made of aluminium. Scrapers are also made detachable, each of them is attached to the body and frame with two screws M6. The width can be changed depending on the thickness and density of snow cover, replacing scrapers.
