摘要： PROBLEM TO BE SOLVED: To provide a trench digger which can efficiently perform a trench digging operation. SOLUTION: The trench digger 1 is provided with an operating machine body 2 connected to a tractor. The operating machine body 2 is rotatably provided with a trench digging body 31 for excavating soil in a field by rotation to dig a trench. The operating machine body 2 is provided with a trench shaping body 33 which can move vertically for shaping the trench at the back in the traveling direction of the trench digging body 31. A gas spring 61, which is an energizing body for moving the trench shaping body 33 downward, is provided between the operating machine body 2 and the trench shaping body 33. While the trench digging body 31 digs the trench at a start position of the trench digging operation, it goes down to a predetermined position, whereby the trench shaping body 33 is pushed to move upward relative to the operating machine body 2. Then, when the tractor travels, the trench shaping body 33 moves downward relative to the operating machine body 2 by the energizing force of the gas spring 61. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a working vehicle that can accurately form a desired ditch set by an operator in an agricultural field.SOLUTION: A tractor detects a grounding position of a ditch digging machine and an agricultural field surface when forming the ditch in the agricultural field by an automatic control (S3). With the grounding position being the reference point, the ditch is accurately formed up to the set initial depth at the starting end part of the ditch by lowering the ditch digging machines, and the ditch is formed in the agricultural field with the predetermined inclination from the starting end part (S4).

摘要： PROBLEM TO BE SOLVED: To reduce the size and weight of an agricultural work vehicle to facilitate the manual traveling operation of the working part.
SOLUTION: A trench digger 1 is provided with an attaching part 10 to be attached to the rear part of a traveling body 90, a movable offset mechanism 20 placed at a side of the traveling body 90 and attached to the attaching part, and a working part 50 placed at the rear end of the offset mechanism in a horizontally rotatable manner and performing the trench digging work. The offset mechanism 20 has a hitch frame 11, an upper swing arm 21, a lower swing arm 22, an offset arm 27 and a rear arm 24 to form a parallel link mechanism. The working part 50 has a frame part 51 extending sideways from a supporting shaft 35 attached to the rear arm 24. The upper swing arm 21 and the frame part 51 function as strength members, and the power transmission mechanism part for these members is placed independent of the upper swing arm 21 and the frame part 51. The working part 50 can be moved to a desired work position by the displacement of the offset mechanism 20 and the rotation of the frame part 51.

摘要： PURPOSE:To rationally conduct excavation by a method wherein the diameters of excavation screws at two ends are increased to a value higher than that of an excavation screw nipped between the excavation screws at two ends. CONSTITUTION:An excavation shaft 2 to which three screws are attached is arranged at an excavator body and a bracing 4 for a screw is mounted. Diameters phiD0 of screws at two ends is increased to a value slightly higher than a diameter phiD of a central screw. Further, in execution of a work, after a pile hole for one element is excavated at a pitch narrowed by an amount equivalent to a lap between the pile holes at two ends of three pile holes, a remaining pile train is excavated in such a state to be lapped with a preceding excavated pile hole.
