The rotary snowplow according to claim 1, characterized in that a brush means for removing snow adhering to the road shoulder wall is provided on one side of the snow removal device in the width direction.
The rotary snowplow according to claim 2, characterized in that the brush means has bristles protruding laterally arranged in a vertical direction, and the arrangement of the tips of these bristles corresponds to the shape of the wall surface.
The rotary snowplow according to claim 1 or 2, further comprising the transfer device for sending snow discharged from the chute to a snow melting device mounted on the cargo bed of the traveling vehicle.
The rotary snowplow according to any one of claims 1 to 3, characterized in that the snow removal device is detachably mounted on the traveling vehicle.
The rotary snowplow according to claim 1, wherein the snow input opening enlargement member has an upper plate portion and left and right side plate portions that are suspended downward from the left and right edges of the upper plate portion, and these left and right side plate portions are in close proximity to the inner surfaces of the left and right side portions in front of the guide path and can be inserted into the left and right side portions, and the side plate portions are configured to close the gap between the upper plate portion and the upper edge of the side portion when the snow input opening enlargement member is opened.

Description

This invention relates to a rotary snowplow, and more particularly to a rotary snowplow equipped with a snow removal device at the front of the vehicle body. Conventionally, this type of vehicle has been known, such as a rotary snowplow (e.g., Patent Document 1) in which a snow removal device consisting of an auger, blower, and chute is mounted on the front of the vehicle body. During transport, the snow removal device is raised as a single unit to a predetermined height, away from the road surface. During snow removal work, the snow removal device is lowered, and the auger collects the snow accumulated on the road, which is then thrown off the road to a suitable location via the chute by the blower. Alternatively, rotary snowplows (e.g., Patent Documents 2 and 3) are known that efficiently remove snow accumulated on roads by using an airflow and centrifugal force generated by a blower to dispose of the snow collected by the auger. Such rotary snowplows are constructed by mounting a snow removal device, consisting of a helical ribbon-shaped auger and a rotary blower, on the front of the vehicle. Furthermore, the rotary snowplow described in Patent Document 1 is equipped with a hydraulic cylinder for lifting and lowering the snow removal device and a hydraulic pump driven by an engine for vehicle travel and operation, and the snow removal device is driven using this hydraulic pump as a power source.

The following describes Embodiment 1 of the present invention with reference to Figures 1 to 20. As shown in the figures, the rotary snowplow (hereinafter referred to as the snowplow) 1 comprises a road vehicle 2 and a snow removal device 3 detachably mounted in front of the vehicle 2. The snow removal device body 4 of the snow removal device 3 mainly consists of a snow-collecting auger device 5 mounted along the left-right direction (vehicle width direction) and a snow removal device 6 mounted between the auger device 5 and the vehicle 2, equipped with a blower 43 for discharging the snow collected by the auger device 5 in a predetermined direction. Furthermore, the snow removal device 3 includes a snow removal device body 4 and a mounting device 7 that detachably mounts the snow removal device body 4 in front of the vehicle 2 and raises and lowers the snow removal device body 4. This mounting device 7 constitutes a part of the snow removal device 3. The auger device 5 comprises an auger 8 and a casing 9 covering the auger 8. The auger 8 is rotatably supported between the left and right auger support members 10, 10 of the snow removal device body 4. Furthermore, in order to remove snow from the road shoulder wall, the width of the auger device 5 in the vehicle width direction is formed to be approximately 1/2 to 2/3 of the vehicle width of the traveling vehicle 2. As shown in Figure 11 and other figures, a vehicle-side mounting body 12 is provided at the front lower part of the vehicle body 11 of the traveling vehicle 2, to which the mounting device 7 of the snow removal device 3 is detachably attached. This vehicle-side mounting body 12 comprises a pair of left and right mounting brackets 13, 13 fixed to the vehicle body 11, and a left-right connecting rod 14 (Figure 6) connecting these left and right mounting brackets 13, 13.
