Claims

[Scope of utility model registration request]

In a trencher in which endless chain-type excavating bodies a are mounted on a machine frame f in two rows on the left and right, the driving shaft of the excavating bodies a is attached to the left and right shaft ends of a drive shaft 1 that is horizontally supported on the machine frame f. Boss part 3 of chain ring 2
is fitted so as to engage with the drive shaft 1 in the rotational direction and freely slide in the axial direction, and a support arm 7 is fitted on the outer peripheral surface of the boss portion 3 via a bearing 6, 7, machine frame f
During the spacing between the excavating bodies in a double trencher, the excavating body a is integrally or integrally connected to the frame 4 of the excavating body a which is fitted and supported by a guide 5 supported parallel to the drive shaft 1. Regulator.
