Abstract

PURPOSE: To bring linear grooving operation is full automation and efficiency when places for removal of the excavated earth are repeatedly changed.
CONSTITUTION: Hydraulic cylinders 8, 9 are prepared to drive the 1st and the 2nd arm, a turn table 3 can be driven and rotated by a hydraulic pressure motor 10 and there is composed a working arm A which may be free to be driven and swing vertically and be flexible and rotative. Operational valves V1, V2, V3 for cylinders 8, 9, 11 provided for a back plow tractor 5, an operational valve V4 for a turn-table drive motor 10 and an operational valve V5 for a right and a left crawler drive motor 13 of a running tractor body 2 are made to operate electromagnetically and each of the operating part S is connected with a program control mechanism B so that it may be free to be released. Linear grooving operation where excavation, turning, earth-throwing away, change of working positions are repeated is carried out in full automation.
