Description

(54) SNOW CLEANER

This invention relates to snowploughs intended to contain airfield and aerodromes. A snowplow is known that contains a self-propelled chassis on which the blade and the brush 1 are mounted. A disadvantage of this snowplow is that the snow clearance zone is limited by the brush grip width due to the small snow throwing distance of the snowflakes. This deficiency is largely eliminated in a snowplow containing a self-propelled chassis on which a blade, a brush, a blower with discharge air and a nozzle are mounted. 2. The presence of a blower allows to clean large areas of artificial turf. This snowplow is closest to the proposed technical essence. Its disadvantage is that a snow shaft is formed at the border of the strip to be cleaned with a brush, which requires a significant mass flow of air to throw the snow. The purpose of the invention is to increase the E (} x {) snow plow efficiency. The goal is achieved by the fact that the snow thrower is equipped with a screen hinged to the chassis that can be rotated in a horizontal plane and mounted in front of the brush, which is located perpendicular to the longitudinal axis of the chassis. In addition, the screen has a shape corresponding to (} the blade of the blade, and together with the brush and the discharge duct mounted on a common frame hinged to the chassis. Fig. 1 shows the proposed snow plow in the working position; Fig.2 the brush with the screen, side view; in Fig. 3, the same, vdh from above; in Fig. 4 - diagrams

the work of the brush: a) without a screen b) from the screen HOMJ on fng.5 - with his cleanness in the transport position.

The snow plow contains a self-propelled chassis 1 (see Fig. 1) with a swiveling dump 2, Self-propelled 1 mounted power plant 3 and blower 4. Brush equipment including blower 4, screen 5 with axis 6, nebotorno and located a transducer 4 - In terms of the orodal axis of the machine, the frame is 7 with support rollers 8, the supercharger is air inlet 9 with nozzle 10, located. The rear of the machine, the screen 5, the brush 7 and the discharge air duct 9 are connected by frame 11, with the possibility of shifting the power into the transport position: cylinder 12, frame 11 sharnschdao Connected to the frame of the self-propelled chassis 1 l screen 5, located in front of the brush 7, resting. on rollers 8, is installed with the help of axis 6 under the platform to it, allowing the snow to fall to the right side of the machine, and if necessary. On the left (see Fig. 3), the Rotating brush 7 directs the snow remaining after the passage of the blade 2 to the screen 5, which, changing the trajectory of the snow, throws it behind the strip to be cleaned. -Blower 4 delivers air to the injection duct 9 to the nozzle Y. The nozzle 10 directs the air jet to the coating, which blows off the snow remaining after the brush passes. After completion of work, screen 5, the brush 7 and the charging duct 9 connected to it are transferred to the transport position (see FIG. 3). FIG. 4 shows the schemes of operation of a pin without a screen (a) 0 with a screen (b), where the points O and O are indications of. ср / шюю distance of a snow throw from a cleared strip. As can be seen from the diagram (b) f | vg.4, the screen is fixed to the screen, the snow is thrown

along a steeper trajectory relative to the longitudinal axis of the machine and the average snow throw distance beyond the strip being cleaned increases.

With an increase in the snow throw distance beyond the strip being cleaned, the formation of rocks at its boundary is excluded, which will lead to the installation of a less powerful blower.

Claims (2)

Introducing the screen to the brush to set the brush to install the wrap) but with respect to the mash axis, which will shorten the brush length. The location of the brush obuver behind the machine does not increase the base of the self-propelled chassis compared to the npoTOTKttsjvi, making it compact and convenient to move to the transport position, i.e. The snowplough construction will be prompted. Claim 1: A snowplow containing a chassis itself, on which a blade, a brush, a blower with a Cagnegative Bosshch and a nozzle are mounted, which is equipped with a screen that is attached to the chassis with the possibility of horizontal rotation and installation in front of the brush, which is located verpe- cularly relative to the axle of the chassis 2, Snow plow in a.1 from the fact that the screen has the shape of the blade. 3, The slush cleaner of claim 2, characterized in that the screen, the plugs and the discharge air duct are mounted on a soft frame hinged on the chassis.
