In the figure, reference numeral 15 indicates a thrower tube connected to the blower housing, 16 and 17 a transmission mechanism to a crawler-type running section, GL the ground, and VL a vertical snow wall surface.

In the snow blower constructed as in the first embodiment, the snow removal section A is normally positioned as shown in FIGS. 1 and 2 during operation.
In this case, the casing a of the snow collecting section A and the snow collecting tool C are positioned horizontally along the ground GL, as shown in FIG. When the rotary shaft 7 is operated while moving the machine body 4 forward by starting the engine 1, the blower 6 and the rotary snow collection tool C are both driven by the rotary shaft 7, and the transfer tools 13 and 14 move the accumulated snow. The snow is collected and supplied to the blower housing b from the snow intake port 10, and the supplied snow is thrown up by the blower 6 and thrown out from the thrower tube 15, thereby performing snow removal on flat land.

In addition, when the snow embankment is to be removed by tearing it down from its side, the fixing by the fixing means 11 is released once and the casing a and the rotary snow collector C are rotated in the direction of the arrow A in Fig. 1. The entire snow collecting section A is changed to the vertical orientation shown in FIGS. 3 and 4 and is fixed by the fixing means 11 for operation. In this case, the outer end of the snow collecting section A is approximately flush with the outer end surface of the fuselage 4, or protrudes further than that, so the fuselage 4 and the snow collecting section A are aligned with respect to the vertical snow wall surface VL of the snow embankment. As shown in Figure 6, the aircraft 4 can move straight along the vertical snow wall surface VL of the snow embankment without any hindrance, and the snow collection section A can operate in close proximity to the vertical snow wall surface VL of the snow embankment. The snow is collected over a wide area in the vertical direction by the rotating snow collector C and then supplied to the blower part B, and the snow supplied to the blower part B is thrown up by the blower 6 in the same way as in the case of flat area snow removal.
