The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
Referring to fig. 1-4, the present embodiment provides a cable trench quick construction device, which comprises a vehicle body 1 and a walking frame 14, wherein the vehicle body 1 is connected with a bucket 26 through a power mechanism, the walking frame 14 is arranged on one side of the vehicle body 1, the power mechanism is a mechanism inherent to the vehicle body 1, and the bucket 26 can be driven to rotate through the power mechanism, so that the trench digging work can be realized.

Compared with the way of rotating a half gear, when the half gear drives the lifting rod 12 to lift, the diameter of the half gear needs to be large enough to drive the lifting rod 12 to lift by a sufficient height, and obviously, the larger half gear occupies too much space. In the manner described in this embodiment, the cylindrical cam 10 is only required to be high enough to drive the lifting rod 12 to rise to a sufficient height, and the diameter of the cylindrical cam 10 is not required, so that a good tamping operation can be realized.
