Description

The invention relates to a snowplow device adapted to the simultaneous removal of snow from the cleared paths by means of the snowplow attached to it and on the loading platforms linked to it with the raised sides of the conveyor belt. Terov, driven by running gear carts. In the proposed device, in order to use the same working part for both the snow blower and the snowplow, to the right along the carriage wall, the front wall of the body is hinged at one end with such dimensions that, being installed at an angle to the path to be cleaned and the free end attached to the left side wall of the vehicle's hull, it forms a snow plow blade, and being turned (with a winch) to the right extreme position and is attached to the stop posts of the carriage Living the right side wall of a wagon like a snowthrower. The marked front wall of the lower part is provided with a hinged joint with a triangular flap connected to it, which overlaps when the wall is installed as a dump plate.

open end of the conveyor. In the proposed device, when using it for punching snow-covered excavation, the speed gearbox is used to convey the required speed for transmission, such as from scats, to the conveyor, and to prevent breakage of the working part of the undercut suspended from the movement , a slide connected to it was applied, which automatically raised the knife upon entering the crossing or other obstacles, if for some reason the knife was not timely raised. When installing the front wall as a waste shield, as such, for a wider cleaning of snow from the brooks and inter-tracks, it is supplemented at the ends, as is usual on snowplows, with flaps. In the device according to the invention, such a side right flap is locked in the working position by means of a ratchet mechanism.

In the schematic drawing of FIG. 1 shows a longitudinal section of a snow plow device with a mechanical conveyor snow blower; FIG. 2 - view it in the plan; FIG. 3 shows a longitudinal section of a loading and unloading platform with a trailer cart of a snowplow in a different direction; FIG. 4 - view in. plan; FIG. 5 is a diagram of the velocity box used in this device; FIG. b-longitudinal section of the device without a conveyor; FIG. 7 - view it in the plan; FIG. 8 - a general view of it from above.

The proposed mobile snow removal unit consists of three interlinked parts. The front part A serves either as a snowplow for snow from the track, or as a snow remover to lift the snow from the path and transfer it when the conveyor L is used to the second part of device B, which is a conveyor platform with extended sides, with a folding right side and a hinged pivot swivel inside, which can be installed at an angle and throw the snow coming to the platform along the conveyor to the right. The third end part B of the device is similar to the front A, but represents only a snowplow with a tightly closed snow plow. The first part A of the device is made in the form of a wagon with a main frame inclined at an angle of 10 ° to the horizon, with its front end resting on the slide 13, and the rear end on the ordinary ramp. On a frame with a slope, an L conveyor is installed. Further, part A is provided, like a snowplow, with a cutting knife} K, a wall K serving as a snow plow blade, folding side shields 3 and // and a booth O for concentrating control of the cart mechanisms with the help of hindres and levers . Particular in its design is a snow plow blade, which is like the front wall of a wagon, hingedly hinged at one end to one of the uprights of the right side wall of the wagon, and the other prymykuyuyu at an angle of 50 ° to its left lateral wall. The front wall (or blade) is a durable construction shield made of boiler iron, reinforced with corners and having smooth bends along the edge of the lower part for a better snow dump and along the edge of the upper part for

hold it off. The wall (otzal) / С, being suspended from the stoic 1, can be turned by a winch П, with the help of trusses (Fig. 1), passing along the chute 25 and envelopes fixedly mounted guide rollers 26-26 and further with their ends (after bending the rollers 27 - 27) attached to the ears at the free end of the bond. With such a device, the specified wall-shield of the monset can be used either as a snow plow snow plow or, being turned and attached to the support stand of the right side of the cart, can form its right wall and open free snow access to the conveyor L, thus reversing the cart in the snow blower. Shield-blade K in its lower part is equipped with a triangular shield, podarnenny hinged to it, falling down when setting the shield as a longitudinal right wall and covering part of the conveyor between the knife and the shield when the latter is installed as a dump of a snow plow. A special type L conveyor on the chain Gal. I receives movement from the rear axle of the vehicle, through a speed box 55 - 64 attached to the lower main frame, of a simplified type (Fig. 5), controlled from the booth O by means of a shaft and turning off the conveyor or at the speed of movement of the carriage itself, or at a speed of three and a half times greater, or completely shutting it down from work. In the cutting knife / K device (Figs. 6 and 7), a feature is the use of one or two safety rails E attached to the knife in front of it. The sled, the ends curved upwards, when meeting on the way to the flooring of the Crossing, freely shoot up on it, raise the knife at the same time, and thus eliminate its breakdown, if for some reason, it was not lifted in a timely manner. As usual in the snowplow, and in the proposed the device, in order to capture a greater width when cleaning the way, the snow plow blade from the ends is complemented by folding shields 3 and I (Figs. 1 and 6). Both the left and right 3 shields are opened to the working position from the booth using a simeter over the carriage envelope with the help of a gear train 128, 129, 132 controlled from the booth O with a handwheel 135-136. side racks 121 in the envelopes of their guides 126 and 127, with the right guide 127 at the height of the wall of the cart closes the rail 125 entirely to protect it from driving with snow when it is unloaded.

According to the author, the speed of movement of the described snow blower can develop on spans up to 40 kilometers per hour depending on the density and height of the snow. The speed of the snowthrower can be developed up to 15 kilometers per hour at stations and up to 7 kilometers per hour in track notches with large drifts. The speed of snow removal at stations up to 600 cubic meters. meters within 2 minutes with a composition of 6 Pullman platforms equipped with conveyors. The platforms are unloaded in the same amount of time.

The subject matter of the invention.
