Problems solved by technology

The existing loader is mainly composed of two parts: the boom lifting mechanism and the bucket turning mechanism, which are respectively controlled by the boom cylinder and the bucket cylinder to complete the operation. Although the hydraulic system has a compact structure, the hydraulic system is easily affected by oil temperature overheating. Low mechanical efficiency, poor transmission stability, and poor reliability of the hydraulic system, complex maintenance and high cost

Abstract

The invention discloses a metamorphic mechanism type mechanical loading mechanism which comprises a rack, a movable arm control branched chain, a bucket control branched chain and a bucket. The movable arm control branched chain comprises a first driving rod, a first connecting rod and a second connecting rod, the first driving rod, the first connecting rod and the second connecting rod are sequentially connected through revolute pairs, the first driving rod is connected with the rack, and the second connecting rod is connected with the bucket; the bucket control branched chain comprises a second driving rod, a third connecting rod and a triangular connecting rod component, one end of the second driving rod is connected with the rack, the other end of the second driving rod is connected with the third connecting rod and the first connecting end of the triangular connecting rod component, the other end of the third connecting rod is connected with the bucket, the third connecting end of the triangular connecting rod component is connected with the first connecting rod, the second connecting end of the triangular connecting rod component is connected or disconnected with the other end of the first connecting rod, and conversion between the single freedom degree and the double freedom degrees of the mechanism is achieved. The metamorphic mechanism type mechanical loading mechanism has the controllable performance, the adjustable performance and the output flexibility performance, and also has the characteristics of multifunctional stage changes, multiple topological structure changes and multi-freedom-degree changes.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a metamorphic mechanism type mechanical loading mechanism. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in roads, ports, mines, railways and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand and gravel. It can also be used for light shoveling of ore and hard soil. operation. Different auxiliary working devices can also be used for bulldozing, lifting and other materials loading and unloading operations. Loaders are the most widely used construction machinery. With the development of social economy, loaders are increasingly used in urban municipal engineering, garbage cleaning, construction engineering and other occasions. Existing loaders are mainly composed of two parts, a boom lifting mechanism and a bucket turning mechanism, which are respectively controlled by the boom cylinder and...
