Loading mechanism with active metamorphic function

Abstract

Provided is a loading machine with the active metamorphic function. A bucket turnover mechanism of the loading machine is composed of a bucket and a turnover mechanism. The bucket is connected to a big arm through a ninth rotation pair and a tenth rotation pair which are coaxial. The turnover mechanism is composed of a driving piece, a first connecting rod, a second connecting rod and a third connecting rod. One end of the driving piece is connected to a machine frame, the other end of the driving piece is connected with the first connecting rod. the other end of the first connecting rod is connected to the second connecting rod, the other two ends of the second connecting rod are connected with the bucket and the third connecting rod respectively, the third connecting rod is connected with the big arm, a locking device is installed on a rotation pair, and the active metamorphic function is achieved by locking the rotation pair. The loading machine with the active metamorphic function overcomes the shortcomings that a hydraulic system of a hydraulic loading machine is complex, the requirement for machining accuracy is high and oil leakage occurs easily, can achieve active metamorphosis according to different operating conditions, not only has the flexibility of the hydraulic loading machine, but also can achieve the loading operations of two degrees of freedom, and is applicable to manufacturing various loading machines and other engineering machines.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a loading mechanism with the function of active metamorphosis. Background technique [0002] Loader is a kind of earth and stone construction machine widely used in construction projects such as road, railway, construction, hydropower, port, mine. Among them, the hydraulic loader is the most widely used type of loader, but the manufacturing cost of the hydraulic system is high, oil leakage is prone to occur, and maintenance is difficult. These are long-standing thorny problems of the hydraulic loader. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanical mechanism provides a broad development space for construction machinery. The multi-degree-of-freedom controllable mechanism driven by the motor not only has a large working space, flexible movement, and high reliability. At the same time, it also has the adv...

Problems solved by technology

[0004] The purpose of the present invention is to provide a loading mechanism with the function of active cell transformation, which can overcome the disadvantages of traditional hydraulic loaders, such as high maintenance cost, high operating noise, high cost of hydraulic components, and insufficient response, and also has the disadvantages of traditional hydraulic loaders. The type loading mechanism has the advantages of large loading capacity, large working space, and good force. It can reduce the number of active rods, thereby reducing the number of controllable motors, improving the coupling vibration caused by multiple motors working at the same time, and improving the service life of parts and mechanism reliability.
