A first driving rod is connected with a machine frame, and the other end of the first driving rod is connected with a big arm through a second rotating pair; a second driving rod is connected with the machine frame, the other end of the second driving rod is connected with a first connecting rod, and the other end of the first connecting rod is connected with the big arm; a lifting rod is connected with the machine frame, the other end of the lifting rod is connected with a bucket rod, and the other end of the bucket rod is connected with a bucket; a second connecting rod is connected with the lifting rod, the other end of the second connecting rod is connected with a turnover rod through a tenth rotating pair, the middle of the turnover rod is connected with the big arm, and the other end of the turnover rod is connected with the bucket; the second rotating pair and the tenth rotating pair are provided with electromagnetic locking devices with the locking function. The electromagnetic braking initiative metamorphic multi-connecting-rod controllable excavation mechanism not only has the flexibility of a hydraulic excavator, but also can achieve the three-degree-of-freedom excavation through the two driving rods, the manufacturing cost of the excavator is lowered, and the electromagnetic braking initiative metamorphic multi-connecting-rod controllable excavation mechanism is applicable to manufacturing of various excavators and other engineering machines.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an electromagnetic braking 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 con...

Problems solved by technology

[0004] The purpose of the present invention is to provide an electromagnetic braking active variable cell multi-link controllable excavation mechanism. First, it should have the advantages of large working space, large excavation force and good force of traditional hydraulic excavators, and overcome the traditional hydraulic excavator maintenance. The shortcomings of high cost, high operating noise, high cost of hydraulic components, and insufficient response. At the same time, the number of active rods should be reduced to reduce the number of controllable motors and reduce the manufacturing cost of excavating mechanisms.
