Simple loading mechanism with active metamorphic function

Abstract

A simple loading mechanism with the active metamorphic function comprises a rack, a bucket turnover mechanism and a locking device. The bucket turnover mechanism comprises a bucket and a turnover mechanism, the locking device is installed on a revolute pair, and the active metamorphic function is achieved by locking the revolute pair. According to the simple loading mechanism, a connecting rod transmission mechanism is adopted for replacing traditional hydraulic transmission, so that the defects that a hydraulic loader is complex in hydraulic system, high in requirement for machining precision and prone to oil leakage are overcome; because the locking device is adopted for the revolute pair, active metamorphic operation can be carried out according to different operation working conditions; the simple loading mechanism not only has the flexibility of the hydraulic loader but also can achieve loading operation with two degrees of freedom only through one driving rod, the using number of motors is reduced, the manufacturing cost of the loading mechanism is reduced, and the simple loading mechanism is suitable for manufacturing various loaders and other engineering machines.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a simple loading mechanism with an active metamorphosis function. 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 a...

Problems solved by technology

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