Multi-connecting-rod controllable mining mechanism with variable cell function

Abstract

The invention discloses a multi-connecting-rod controllable mining mechanism with a variable cell function. The multi-connecting-rod controllable mining mechanism is characterized in that one end of a big arm is connected on a frame while the other end of the same is connected with a first connecting rod through a second rotating pair, the other end of the first connecting rod is connected with a second connecting rod, and the other end of the second connecting rod is connected with the middle of a fourth connecting rod; one end of a first driving member is connected to the frame while the other end of the same is connected with a bucket rod, and the other end of the bucket rod is connected with a bucket; the middle of the bucket rod is connected with the middle of the second connecting rod; one end of a second driving member is connected to the frame while the other end of the same is connected with a third connecting rod, the other end of the third connecting rod is connected with the fourth connecting rod through a tenth rotating pair, and the fourth connecting rod is connected to the bucket; a first electromagnetic locking device and a second electromagnetic locking device are respectively mounted on the second rotating pair and the tenth rotating pair and used for performing timely locking on a mining machine under different working conditions. The hydraulic mining machine is flexible, and manufacturing cost of the mining machine is lowered.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a multi-link controllable excavating mechanism with metamorphic function. Background technique [0002] Excavator is a kind of common construction machinery, which is mainly used in various engineering operations. Among them, the hydraulic excavator is a type of excavator widely used at present, but the hydraulic excavator has problems such as high manufacturing cost of the hydraulic system and prone to oil leakage. 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 construction machinery. The multi-degree-of-freedom controllable me...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-link controllable excavating mechanism with metamorphic function, which should firstly have the advantages of large working space, large digging force and good force bearing of traditional hydraulic excavators, and overcome the maintenance cost of traditional hydraulic excavators High, high operating noise, high cost of hydraulic components, and insufficient response. At the same time, the number of active parts should be reduced to reduce the number of controllable motors and reduce the manufacturing cost of excavating mechanisms.
