Snow-removing machine

摘要

In a snow-removing machine, an expandable and contractible regulating mechanism (45) is coupled between a steering handlebar (6) of a machine body (3) including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism (45) is comprised of a cylinder connected to the machine body, a piston (51) which divides the inside of the cylinder into a first chamber (49) and a second chamber (50), a piston rod (52) coupled to the piston and connected to the drive section, a communication passage (58,59) permitting communication between the first and second chambers, and an on-off valve (55) for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.
