Abstract

A multi-connecting-rod controllable excavation mechanism based on electromagnetic initiative metamorphism comprises a rack, a large arm swing mechanism, a bucket rod lifting mechanism, a bucket turnover mechanism and an electromagnetic locking device. The large arm swing mechanism comprises a large arm and a swing mechanism. The bucket rod lifting mechanism comprises a bucket rod and a lifting mechanism. The bucket turnover mechanism comprises a bucket and a turnover mechanism. The electromagnetic locking device is installed on a revolute pair, and an initiative metamorphism function can be achieved by electromagnetically locking the revolute pair. According to the excavation mechanism, a traditional hydraulic transmission mechanism is replaced by a connecting rod transmission mechanism, so the defects that a hydraulic system of a hydraulic excavator is complex and prone to oil leakage and the like are overcome. Due to the fact that the electromagnetic locking device is adopted in the revolute pair, initiative metamorphism can be achieved according to different operation working conditions, and the excavation mechanism not only has the flexibility of the hydraulic excavator, but also can achieve 3-DOF excavation operation by utilizing two initiative rods, lowers the manufacturing cost and is suitable for manufacturing various excavators and other engineering machinery.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an electromagnetic active variable cell multi-link controllable excavating mechanism. Background technique [0002] Excavator is a common construction machine, which is mainly used in various earthwork constructions. Among them, the hydraulic excavator is the most widely used type of excavator, but the manufacturing cost of the hydraulic system is high, and problems such as oil leakage are prone to occur. These are long-standing thorny problems of hydraulic excavators. However, traditional single-degree-of-freedom mechanical excavators, commonly known as "electric shovels", can only achieve simple and unchangeable trajectory output, so they cannot be used in a wide range of fields like hydraulic excavators. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a broad development space for constructio...
