Improvement of performance of rotary snow removing wheel

This paper concerns the remodelling of a working machine for a small rotary snow removing wheel into a working machine (two stage type) for test to examine the snow removing performance. The auger, blower and travelling unit may be operated individually and independently. The revolutions per minutes and torque of auger and blower were measured under some testing conditions (about 60 conditions of testing data). Based on the measured data, multiple regression analysis was conducted which is a kind of multivariate analysis. As a result, the torques of auger and blower and removed snow weight, which are important elements to know the snow removing performance could be represented by a regression formula with high estimation accuracy including the working conditions (vehicle speed, removed snow width and height), number of revolutions of the auger and blower, snow conditions (density and hardness), pitch and spiral blade number of auger ribbon and number of auger blades. Our findings include the following: (1) The increase in snow hardness implies augmented auger torque; (2) The small number of revolutions of the auger means increased auger torque; (3) Increase in removed snow weight has a relation with the rise of blower torque; and (4) The growth of the pitch of auger ribbon increases the torque of auger and blower, but the influence on torque of the spiral blade number of auger ribbon and the number of blades of blower is small.
