らねばならず、調節の為の油圧シリンダー等の伸縮装置
が設けられていなかったのである。Furthermore, when rotating the excavating device relative to the machine frame body, manual effort was required, and there was no expansion/contraction device such as a hydraulic cylinder for adjustment.
故に、オペレーターが人力により掘削装置の先端を押し
て回動させピンの位置を変えていたのである。Therefore, the operator manually pushed and rotated the tip of the drilling rig to change the position of the pin.
これには体力が必要であり、掘削装置の角度変更を面倒

していたのである。Also, as in Utility Model Application Publication No. 48-35502, there was a device that made the excavation equipment rotatable using telescoping devices such as two hydraulic cylinders installed on the left and right sides, but if both were made into telescoping devices, The excavating rig is rotated only for special operations, and during most general operations the excavating rig is rotated by the rotation motor together with the machine frame itself. Since the main body was fixed with a telescoping device, the shocks at the beginning and end of rotation caused too much shock load to be applied to the hydraulic system, causing damage to the hydraulic system.

強度が増加するのである。(F) Effects of the Invention As described above, the present invention mounts the excavating device to the machine frame body, which is rotatably equipped with respect to the traveling device, so as to be rotatable from side to side in plan view. An extensible member is attached to one side, and a fixed frame that can be freely engaged and detached with a pin is attached to the other side, so that when the drilling equipment is fixed in the front position in a plan view, it can be rotated left and right and fixed in the front position. Firstly, since the extendable member and fixed frame are pivoted in a "C" shape with the pivot side of the machine frame widened, firstly, by providing the extendable device, the rotation angle is stepless; The left and right rotation of the equipment can be done by hydraulic pressure, etc., without relying on human power, and since a fixed frame is provided, when the excavation equipment is fixed in front of the machine frame for normal work, it can be expanded and contracted. Since the shock is not received by the fixed frame when the device rotates, there is no shock applied to the hydraulic system.In addition, the fixed frame and telescoping device are connected by a reverse “-・” design with the pivot side of the machine frame widened. By arranging it in the shape of a letter, the impact during rotation can be received by buckling load instead of bending load.
The strength increases.
