成が記載されている。2. Description of the Related Art A trench excavator generally has a rotary excavating blade and is mounted on a rear portion of a tractor. The rotary force of the rotary excavating blade is transmitted from a PTO shaft of the tractor to a universal joint via a transmission shaft. Was there. For example, the groove excavator described in Japanese Utility Model Publication No. 6-19651 by the same applicant is driven to rotate, and the groove is formed by being driven to rotate with a transmission shaft arranged on the tractor so as to become lower as the distance from the tractor increases. A rotary drilling blade for digging can be attached,
A trench digging machine, comprising: a ground plane; and a rotating shaft that is attached so as to be inclined with respect to the transmission shaft and is rotated by the transmission shaft. Therefore,
With that configuration, when the transmission shaft rotates, the rotation shaft to which the rotary drilling blade is attached rotates. The rotation axis is the transmission axis,
Since it is attached at an angle, the operation is convenient and the degree of freedom of the installation angle of the rotating shaft with respect to the ground plane is large. or,
Since the rotation axis of the rotary drilling blade is tilted with respect to the ground plane, the rotary drilling blade is tilted and rotated with respect to the ground plane.
Therefore, it is disclosed that the excavated and discharged soil is less likely to be spread and fall into pieces at a place appropriately separated from the page (2) groove due to the centrifugal force, and to become a fill. A configuration is described in which a finishing plate is provided behind the excavating blade of the ditching machine to shape and finish the groove width and the groove bottom.

溝整形作用を果たす。The groove finishing plate is arranged close to the rear portion of the rotary excavating blade, and the groove finishing plate is provided with a rotary link so that it can be folded, so that the operator can sit on the tractor or the like. , The string finishing plate is folded upward by instructing the rotation link with a string or the like, the soil is excavated at the excavating portion, and when the predetermined depth is reached, the groove finishing plate is folded back to proceed. Therefore, since a predetermined depth is reached from the work starting point, there is no need for artificial correction work for post work. Further, since the groove finishing reaction force is used as the means for compressing the rotary link in the state where the groove finishing plate is installed, the groove shaping action is achieved only by returning the finishing plate to the installed state via the link means.
