ON PERFORMANCE OF A TWO STAGE ROTARY SNOW BLOWER

We manufactured two types of augers, a screw and rake type auger and a ribbon screw type auger to further improve the performance of the two stage rotary snow blower that is now considered as the most effective remover in view of the diversified nature of snow in Japan. After installing each of them on a base machine actually used, we examined the performance characteristics while changing revolutions and snow nature. We also prepared two blowers (four-blade blower and five-blade blower) to examine their difference. The results of the test are summarized as follows: (1) 3-element ribbon screw type auger was superior to 2-element screw and rake type auger in general performance. (2) Snow removing performance considerably depends on the combination between blower and auger circumferential speed. Maximum snow removing capacity (t/h) is achieved at such a combination as the blower speed is low, while the auger speed is high in order to increase the capacity of snow gathering. Blower high speed is provided to get the distance of snow ejection. In this case, low auger speed produces better result. (3) The 7-blade blower was superior in performance to the 5-blade blower. This, however, depends on the volumetric capacity margin of the blower housing. /Authors/
