Abstract

WORKING ORGAN OF ROTARY SNOW CLEANER, comprising a case with a central loading window, two horizontal upper and lower augers and blades installed in the case. | each of which is wound in opposite direction, a rotor mounted from the rear side of the body and communicated with it by means of; a loading window, a divider in the form of a horizontal partition fixed from the front side of the body between the screws, which is characterized by the fact that, in order to improve work efficiency by ordering the rotor loading process, the loading window is made from the bottom screw, the blades of which have a winding direction to the center and opposite direction, winding of the blades of the upper screw, and in the end zones of the dissector holes are made.

about:

The invention relates to road snowplows, namely to snow augers.

Known working body of the rotor snowplow, comprising a housing with a central loading window, installed in the housing two horizontally arranged upper and lower augers, the blades of each of which are wound counter, a rotor mounted on the back side of the housing and communicated with it through the loading window, a divider in the form of a horizontal Negotiations Rods fixed from the front side of the body between the screws Tlj

The feeding by the feeder of snow mass B to the unloading zone of the rotor worsens the conditions for the formation of a snow prism on the rotor blade, thereby reducing the drop range. In addition, when the rotor blade is filled with snow mass, it experiences the effect of centrifugal forces (5000-7000 kg (that squeeze the snow mass back from the rotor). .

Research has shown that with the supply of snow mass only in the lower part of the loading window of the rotor, the range of waste increases by 20% and the emission of snow mass from the rotor blades is significantly reduced.

The purpose of the invention is to increase the efficiency of operation by strengthening the rotor loading process.

The goal is achieved by the fact that in the working body of the rotor snowplow, comprising a housing with a central loading window, two horizontally arranged upper and lower augers mounted in the housing, the blades of each of which are wound oppositely, a rotor mounted on the back side of the root and communicated with it through the boot window, the divider in

as a horizontal partition fixed from the front side of the housing between the screws, the boot window is made from the bottom screw, the blades of which have the direction of winding towards the center and opposite to the direction of winding of the blades of the upper screw, and holes are made in the end zones of the dissector. FIG. Figure 1 shows a front view of a working snow blower; in fig. 2 shows an ordered rotor loading process, the circuit in FIG. 3 shows section A-A in FIG. in fig. 4 is a section BB in FIG.

The working body consists of a housing 1 with a central loading window 2, closed in the upper part, on the back side of which rotor 3 is mounted, and on the front one are mounted lower 4 and upper 5 augers with backward-waving blades divided by divider b, on the sides of which there are holes 7 connecting the working areas of the screws

4 and 5. Blades of the upper screw 5

moreover, they have a direction of winding from the center, opposite to the direction of winding of the blades of the lower screw 4.

The rotary snow plow tool is mounted on the base machine on which the engine is installed to drive it. During the operation of the snow blower, due to the translational movement of the base chassis, the tool is inserted into the snow face, and the screws 4 and 5 rotate and cut snow into the face and transport it. In this case, the top

auger 5 transports snow from

center of the feeder to the hole m 7, where:. the snow is overloaded to the lower auger 4, which is transported to the center of the feeder and is loaded into the window.2.

whereby ordering of the rotor loading process is achieved.

The technical and economic efficiency of the proposed device is achieved by increasing the snow throw distance.
