DUSTING BOOM FOR DUSTING MACHINE

摘要

PROBLEM TO BE SOLVED: To obtain the subject dusting powder-sprinkling boom that can increase dust-sprinkling workability as it is readily adaptive to the sprinkling width with reduced damage even in narrow and troublesome places by linking a specific auxiliary boom to the top end of the pipe boom. ;SOLUTION: A flexible and stretchable auxiliary boom 3 is linked to the top edge of the pipe boom 2 that stretches out in the transverse direction to the machine body. When dusting powder-sprinkling operation is done as the pipe boom 2 is stretched in the transverse direction to the machine body, the pipe boom can sprinkle in the width of the pipe boom in the state that the auxiliary boom at the top of the pipe boom is in the rest. Further in the case that the auxiliary boom 3 is stretched or is kept stretchable, the dusting powder can be sprinkled over a wide range of the pipe boom and the auxiliary boom.;COPYRIGHT: (C)2000,JPO
