Abstract

This invention relates to hand-operated snow plows for clearing hard-to-reach places. The aim of the invention is to increase the efficiency of the development of the snow flank. Snow plow for snow removal in hard; accessible places comprises a housing 1 in which a rotary thrower with blades 6 is installed, having a horizontal axis of rotation. A guide vane 4 is placed in the upper part of the body. Perpendicular to the blade 6, U-shaped cutting elements are rigidly fixed with front 9 and side 10 knives. The front knife 9 is parallel to the outer edge of the blade 6 at a distance from the axis of the thrower, equal to the radius of rotation of the edge of the blade 6, and its length is equal to the width of the blade 6. When turning the throwers, the knives 9 and 10 cut through the snow in the hole, separating it from the array. The cut snow is picked up by the blades 6 and thrown to the side, through the guiding apparatus 4. 1 Cp. F-crystals. 4 il.

This invention relates to a manually operated snow plow for clearing snow from hard to reach places.

The aim of the invention is to increase efficiency by reducing the energy intensity of the development of the snow flank.

with to the place of work. The engine is started, causing the shaft 2 to rotate with blades 6 and blades 9 and 10 through chain gear 7. Rotating blades 9 and 10 cut through the snow bottom of the slot, a part of the snow massif separates from it, which is picked up by the blade 6 and is thrown out Yush, siy apparatus 4. In this case, the blade 6 does not participate in the cutting of snow, but only transports separated from

The snow plow contains case 1, its internal array is part of it which reduces energy

This shaft is mounted 2, attached to the side walls of the housing 1 with bearings 3. The axis of the shaft 2 is located horizontally and perpendicularly to the direction of movement of the snowplow. In the upper part of the housing 1 there is a guiding apparatus 4. In the lower part, the housing 1 has a flat bearing surface 5. The blades 6 of the rotary thrower are rigidly attached to the shaft 2, to drive which the chain drive 7 from the engine (not shown) is used for rotation. on the sprocket 8, rigidly mounted on the shaft 2. U-shaped cutting elements with front ones are rigidly attached to each blade 6

The cost of the development process of the snow plow. Flanging 11 contribute to the retention of snow on the blade 6 when it turns.

Claims (2)

1. Snow plow for removing snow in hard-to-reach places, comprising a housing, a rotary thrower mounted in a housing with a horizontal transverse axis of rotation, a guide vane located in the upper part of the housing, characterized in that in order to increase efficiency by reducing the snow development power intensity smack he the knife 9 and the side knives 10, mounted perpendicular to the blade 6. The Pe-25 is equipped with U-shaped cutting elements - the front knife 9 is parallel to the outer with the front and side knives, mounted to the edge of the blade 6 at a distance from the jointed perpendicular Each blade 2, equal to the radius of rotation of the blade and rigidly connected with it, is 6, and its length is equal to the width of the blade 6. The front knife is parallel to the outer blade 6 and flanges 11 are formed; from the axis perpendicular to the plane of each l o-30 of the shaft, equal to the radius of rotation of the said mouth 6 and directed towards the rotating edge of the blade, and its length is equal to the width not the last. The snow blower is provided with a handle (not shown) for holding it by hand. In order to clear snow in hard-to-reach places, the snowplow manually delivered the snow. 2. A snow plow according to claim 1, characterized in that each blade is made with screenings perpendicular to its plane and directed in the direction of rotation. with to the place of work. The engine is started, causing the shaft 2 to rotate with blades 6 and blades 9 and 10 through chain gear 7. Rotating blades 9 and 10 cut through the snow bottom of the slot, a part of the snow massif separates from it, which is picked up by the blade 6 and is thrown out Yush, siy apparatus 4. In this case, the blade 6 does not participate in the cutting of snow, but only transports separated from an array of its part which reduces energy The cost of the development process of the snow plow. Flanging 11 contribute to the retention of snow on the blade 6 when it turns. Invention Formula 1. Snow plow for removing snow in hard-to-reach places, comprising a housing, a rotary thrower mounted in a housing with a horizontal transverse axis of rotation, a guide vane located in the upper part of the housing, characterized in that in order to increase efficiency by reducing the snow development power intensity smack he Equipped with U-shaped cutting elements with front and side blades installed perpendicular to each blade and rigidly connected with it, while the front knife is located parallel to the outer edge of the blade at a distance from the shaft axis equal to the radius rotation of the specified edge of the blade, and its length is equal to the width blades. 2. A snow plow according to claim 1, characterized in that each blade is made with screenings perpendicular to its plane and directed in the direction of rotation. 1 / I-A
