Auger snow-removing machine

摘要

An auger snow-removing machine includes left and right forward rotation augers rotatable in a first direction during snow removal and left and right reverse rotation augers rotatable in a second direction opposite the first direction during the snow removal. The forward and reverse rotation augers are coaxially disposed in alignment in a width direction of an auger housing within the housing. Distal ends of the left forward rotation auger and the right reverse rotation auger have phases set to substantially simultaneously reach a lowermost location when the forward and reverse rotation augers rotate. Distal ends of the right forward rotation auger and the left reverse rotation auger have phases set to substantially simultaneously reach the lowermost location when the forward and reverse rotation augers rotate.

1. An auger snow-removing machine comprising:
left and right forward rotation augers rotatable in a direction from an upper side of the forward rotation augers toward a front lower side of the forward rotation augers during a snow-removing operation of the machine; left and right reverse rotation augers rotatable in a reverse direction opposite to the direction of rotation of the left and right forward rotation augers during the snow-removing operation; an auger housing; a blower housing disposed behind the auger housing at a widthwise central portion of the auger housing; and a blower disposed inside the blower housing, the left and right forward rotation augers and the left and right reverse rotation augers being coaxially disposed and aligned with one another in a width direction of the auger housing within the auger housing, all of the left and right forward rotation augers and the left and right reverse rotation augers having the same rotational speed, the left and right forward rotation augers being located either inside or outside the left and right reverse rotation augers in the width direction of the auger housing, each of the left and right forward rotation augers and the left and right reverse rotation augers being formed by a combination of two spiral-shaped strip-like auger members, each of the auger members having a spiral direction such that the forward rotation augers, while undergoing forward rotation, collect snow toward the widthwise central portion of the auger housing and the reverse rotation augers, while undergoing reverse rotation, collect snow toward the widthwise central portion of the auger housing, the left forward rotation auger having a distal end in the direction of rotation of the left and right forward rotation augers, the right reverse rotation auger having a distal end in the direction of rotation of the left and right reverse rotation augers, the distal end of the left forward rotation auger and the distal end of the right reverse rotation auger having phases set such that the distal end of the left forward rotation auger and the distal end of the right reverse rotation auger substantially simultaneously reach a lowermost location when the left forward rotation auger and the right reverse rotation auger rotate, the right forward rotation auger having a distal end in the direction of rotation of the left and right forward rotation augers, the left reverse rotation auger having a distal end in the direction of rotation of the left and right reverse rotation augers, the distal end of the right forward rotation auger and the distal end of the left reverse rotation auger having phases set such that the distal end of the right forward rotation auger and the distal end of the left reverse rotation auger substantially simultaneously reach the lowermost location when the right forward rotation auger and the left reverse rotation auger rotate, and the distal end of the right forward rotation auger having a phase shifted 90 degrees from a phase of the distal end of the left forward rotation auger.
