Hybrid-driven controllable excavation mechanism

Abstract

The invention discloses a hybrid-driven controllable excavation mechanism which comprises a first excavation arm, a second excavation arm, a forward shovel type bucket and a frame, wherein the first excavation arm and the second excavation arm are respectively formed by the connection of a two-degree-of-freedom hybrid-driven controllable mechanism with the forward shovel type bucket through a complex hinge and a connecting rod. The first excavation arm and the second excavation arm are both arranged on the frame and subjected to hybrid-driving of two high-power conventional motors and two low-power servo motors, and therefore, the requirements for large excavating force and concurrently flexible track output can be met simultaneously. The hybrid-driven controllable excavation mechanism disclosed by the invention can solve the problems that the traditional single-degree-of-freedom mechanical excavation mechanism is simple in implementation action, the hydraulic excavation mechanism is probably subjected to oil leakage, etc. Besides, the whole excavation mechanism has the advantages of high excavation efficiency, low manufacturing cost and low processing and assembling requirements.

Description

technical field [0001] The invention relates to a construction machine, in particular to a hybrid driving controllable excavating mechanism. Background technique [0002] Excavator is an important construction machinery, which is widely used in mechanized construction such as industry, transportation, energy, farmland transformation, water conservancy, civil construction, mining and modern military engineering. So far, there are mainly two types of excavators: 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 startability and is prone to leakage due to wear and tear of internal components, and there are many components involved, and the leaked hydraulic oil will cause environmental pollution. At the same time, overheating and inability to work occur. As the functional requirement...

AI Technical Summary

Problems solved by technology

However, the traditional single-degree-of-freedom mechanical excavator has a large and complex structure and cannot complete flexible and changeable excavation actions. Even if it is only used for mining, it often encounters difficulties, such as: the bucket teeth cannot produce Larger cutting force; For cleaning the foundation of inclined seam, the unloading height into the loading truck is too small, etc.

At present, there is a consensus in the field of construction machinery that the actions that mechanical excavators can perform are simple and difficult to change, and many actions cannot be realized; hydraulic excavators can flexibly perform various engineering actions, but there are requirements for hydraulic system components High, short life, oil leakage and other defects
