Two freedom degree controllable type loading mechanism with initiative metamorphic function

Abstract

Disclosed is a two freedom degree controllable type loading mechanism with an initiative metamorphic function. The two freedom degree controllable type loading mechanism with the initiative metamorphic function comprises a machine frame, a drive rod, a first rocker arm, a first linkage, a pull rod, a second rocker arm, a second linkage, a large arm, a scraper bucket and two locking devices, wherein one end of the drive rod is connected with the machine frame, the other end of the drive rod is connected with one end of the first rocker arm, the other two ends of the first rocker arm are respectively connected with one end of the pull rod and one end of the first linkage, the other end of the pull rod is connected with the scraper bucket, the other end of the first linkage is connected one end of the second rocker arm, the other two ends of the second rocker arm are respectively connected with one end of the second linkage and one end of the large arm, the other end of the second linkage is connected with the machine frame, the other two ends of the large arm are respectively connected with the scraper bucket and the machine frame, the locking device is installed on a rotation pair, and the locking device can be locked and loosened according to different work conditions so as to complete operation. The two freedom degree controllable type loading mechanism with the initiative metamorphic function uses a linkage mechanism to replace a hydraulic mechanism, can achieve the initiative metamorphic function through the locking device, can achieve two freedom degrees of loading operation only through the one drive rod, and is simple to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of loaders, in particular to a two-degree-of-freedom controllable mechanism-type loading mechanism with an active metamorphosis function. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. , hard soil, etc. for light shoveling and digging operations. There are many deficiencies and shortcomings in the commonly used hydraulic loaders. For example, the hydraulic components require high machining accuracy and are difficult to manufacture. Moreover, the maintenance cost is high during use, the operation is difficult, the structure is complex, and the efficiency is low. The current multi-link mechanism controls the multi-degree-of-freedom link mechanism, and often needs to use the same number of c...

Problems solved by technology

[0003] The purpose of the present invention is to provide a two-degree-of-freedom controllable mechanism-type loading mechanism with the function of active cell transformation. Firstly, it adopts multi-link transmission, which overcomes the disadvantages of complex hydraulic transmission structure, difficult operation, low efficiency, and high cost. The active metamorphic mechanism is adopted, which reduces the number of components and motors, simplifies the structure of the mechanism, increases the reliability of the control, and reduces the manufacturing cost and maintenance cost of the loading mechanism.
