Automatic snow throwing chute attitude control device of rotary blower and instruction manner null of snow throwing chute

摘要

PROBLEM TO BE SOLVED: To improve work efficiency by detecting a position of a snow remover by utilizing GPS, determining a target value of posture of a snow throwing chute at a snow throwing point in a snow removing work path, and operating the snow remover in accordance with deviation amount obtained by comparing it with a current value. ;SOLUTION: A position of a snow remover is detected by utilizing GPS, and a target locus of attitude of a snow throwing chute in a snow removing work path is determined based on a position which is given and attitude data in advance. Next, attitude of a current snow throwing chute which is detected by attitude detection sensors 6A, 9A 10A along the target locus is feedback-controlled. Then, the snow remover is driven along the snow removing work path, and attitude of the snow throwing chute is adjusted automatically along the snow removing work path to charge snow at a snow charging point which is scheduled. A position of a self-car of the snow remover is detected by a GPS receiver 15, and a position of the snow remover is detected stably and accurately without being affected by slip of wheels even in the case of snow removing work over a long distance. Consequently, it is possible to reduce work burden of the snow removing work and improve its work efficiency.;COPYRIGHT: (C)1998,JPO
