Abstract

The invention discloses a controllable excavating mechanism which comprises a rack, a control branch chain, a lifting branched chain, an overturn branch chain and a scraper bucket, wherein the control branch chain comprises a first driving rod and a movable arm; one end of the first driving rod is articulated with the rack, and one end of the movable arm is articulated with the other end of the first driving rod; the lifting branch chain comprises a second driving rod, a second connecting rod and a third connecting rod, a lifting rod, one end of the second driving rod is articulated with the rack, one end of the second connecting rod is articulated with the other end of the second driving rod, one end of the third driving rod is articulated with the middle of the second connecting rod, one end of the lifting rod is articulated with the other end of the third connecting rod, the other end of the second connecting rod is articulated with the middle of the movable arm, and the other end of the movable arm is articulated with the middle of the lifting rod; the overturn branch chain comprises a third driving rod and an overturn rod, one end of the third driving rod is articulated with the rack, and one end of the overturn rod is articulated with the other end of the third driving rod; the upper part of the scraper bucket is articulated with the other end of the lifting rod, and the lower part of the scraper bucket is articulated with the other end of the overturn rod. The excavating machine is relatively flexible, and can be used for avoiding the defects of high accuracy, oil leakage and the like of a hydraulic element.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a controllable excavating mechanism. Background technique [0002] An excavator is a commonly used construction machine. Among them, hydraulic excavators are the most widely used, and their hydraulic components require high precision, resulting in high manufacturing costs of the hydraulic system, and are prone to oil leakage and other problems. These are long-standing thorny problems of hydraulic excavators. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a wide range of development space for construction machinery. The multi-degree-of-freedom controllable mechanism driven by the control motor not only has a large working space, flexible movements, and can complete complex movements. Trajectory output, but also has the advantages of low manufacturing cost, simple maintenance and so on. [0004...
