Two-degree-of-freedom chain bucket type electrically-controlled trenching machine

Abstract

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.

Description

technical field [0001] The invention relates to the field of chain bucket type ditching machines, in particular to a two-degree-of-freedom chain bucket type electric control ditching machine. Background technique [0002] A multi-bucket excavator is an excavating machine that uses multiple buckets to continuously excavate, transport and unload. It has the characteristics of continuous operation, high productivity, and low unit energy consumption. It is especially suitable for excavating with low hardness and without large sand stony soil. Chain bucket trenching machine is a kind of multi-bucket excavator. It mainly uses multiple buckets installed on the endless chain of the bucket frame for continuous excavation, transportation and unloading operations. It is mainly used for digging ditches, canals, and correcting slopes. And mine stripping, mining and stockyard operations. [0003] Although the bucket chain trencher has been widely used in many fields, which effectively i...
