Title:
SELF-ADVANCING SOIL IMPROVING MACHINE AND OPERATING METHOD THEREOF
Document Type and Number:
Japanese Patent JP3891378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve workability by performing inspection and maintenance of each equipment such as a material soil conveyor, an improving material feeder and a mixer individually by remote operation in a required place.
SOLUTION: At the time of inspection and maintenance, a radio control switch 14 is turned on and an operating mode change-over switch 13 is changed over to a maintenance mode. Then a contact 13b is turned on, and relays RYA- RYD of a remote control circuit 33A are excited to turn off contacts A1, B1, C1, D1 and to turn off contacts A2, B2, C2, D2. When a first switch of a remote control panel is turned on, a first contact CH1 of a receiver 32 is turned on, and an input current flows from a controller 34 through a contact A2 to rotate an improving material feeder normally. When second, third and fourth switches of the remote control panel are turned on, the improving material feeder is reversely rotated respectively in the same way, and a material soil conveyor is rotated normally and reversely. Each equipment can therefore be operated individually in a position where the interior of the equipment is visible, so that inspection and maintenance can be easily performed by one person.
