Backacting shovel working device of excavator

Abstract

The invention discloses a backacting shovel working device of an excavator and relates to the field of industrial machinery. The backacting shovel working device of the excavator comprises a backacting shovel arm, a bucket rod, axles, a steel rope bucket and a movable rod, the backacting shovel arm is provided with two traction pulleys, the traction pulleys are connected with the axles through steel ropes, the bucket rod is provided with four regulating holes, and the regulating holes are movably connected with the bucket through the movable rod. The backacting shovel working device of the excavator effectively reduces the friction at the hinge parts of the components; the backacting shovel working device of the excavator is difficult to damage due to abrasion and does not need to frequently change components, and the hopper angle is changed; the movable rod can be connected with the four regulating holes at different positions so as to increase the shovel amount; the backacting shovel working device of the excavator is simple in structure, and each function is greatly improved.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to an excavator backhoe working device.
