The invention discloses a two-degree-of-freedom chain bucket type electrically-controlled trenching
machine. The two-degree-of-freedom chain bucket type electrically-controlled trenching
machine comprises an electrically-controlled trenching mechanism, a conveying chain,
shovel buckets and a material guiding plate, and the electrically-controlled trenching mechanism comprises a main arm adjustingmechanism and a bucket frame adjusting
branch chain. The electrically-controlled trenching mechanism adopts connecting rod transmission to replace hydraulic transmission of an existing chain bucket type trenching
machine, a motor installed on a rack achieves power input through two drive rods, therefore, the manufacture cost is reduced, a
control system is simplified, the
failure rate is effectively decreased, and
energy consumption and the maintenance cost are effectively reduced. The electrically-controlled trenching mechanism is a planar two-degree-of-freedom mechanism, a bucket frame can achieve two-degree-of-freedom
coupling movement output, and then large-space high-flexibility posture adjustment of the electrically-controlled trenching mechanism is achieved. Compared with the existing chain bucket type trenching machine of which the bucket frame only can achieve single-degree-of-freedom lifting, the two-degree-of-freedom chain bucket type electrically-controlled trenching machine has the larger
working space and the better flexibility, can achieve operation in a more complex environment, and is obvious in technological
advantage and wide in market prospect.
