Abstract

The invention relates to a hybrid drive controllable parallel-connection excavation mechanism. The hybrid drive controllable parallel-connection excavation mechanism comprises an excavation arm, a forward shoveling type bucket and a machine frame, wherein the excavation arm is a three-degree-of-freedom hybrid drive controllable mechanism and is formed by connecting a composite hinge, a connecting rod and the forward shoveling type bucket. The excavation arm is installed on the machine frame and driven by a large-power normal-speed motor and two small-power servo motors in a hybrid mode, and large excavation force and certain output flexibility can be realized. The hybrid drive controllable parallel-connection excavation mechanism not only resolves the problems that a traditional single-degree-of-freedom mechanical excavation mechanism is simple in realization movement, and a hydraulic excavation mechanism is prone to oil leakage, but also resolves the problem that an existing two-degree-of-freedom hybrid drive excavation mechanism needs two normal-speed motors, eliminates one normal-speed motor, has a certain energy-saving effect and is low in manufacturing cost and high in excavation efficiency.

Description

technical field [0001] The invention relates to a construction machine, in particular to a three-degree-of-freedom hybrid drive controllable excavation mechanism Background technique [0002] As an important construction machinery, excavators are widely used in mechanized construction such as industry, transportation, energy, farmland transformation, water conservancy, civil construction, mining and modern military engineering. At present, excavators are mainly classified into two types: hydraulic and mechanical. Hydraulic excavators have the advantages of simple structure, light weight, and many complex actions, and are widely used. However, hydraulic excavators use hydraulic oil as the power transmission medium, which has poor starting performance and is prone to leakage due to wear of internal components, and there are many components involved. At the same time, there are phenomena such as overheating and weak work. Due to the limitations of the hydraulic system, hydra...
