Mechanical electric excavation mechanism

Abstract

The invention discloses a mechanical electric excavation mechanism, which comprises a movable arm lifting mechanism, a dipper handle swinging mechanism, a dipper reversal mechanism and a rack. The movable arm lifting mechanism comprises a movable arm and a lifting mechanism, wherein one end of the movable arm is hinged with the rack, and the other end of the movable arm is hinged with a dipper rod; and one end of the lifting mechanism is hinged with the movable arm, and the other end of the lifting mechanism is hinged with the rack. The dipper rod swinging mechanism comprises a dipper rod and a swinging mechanism, wherein the dipper rod is hinged to the movable arm; one end of the dipper rod is hinged with the swinging mechanism, and the other end of the dipper rod is hinged with a dipper; and the swinging mechanism is hinged between the dipper rod and the rack, and is also hinged with the movable arm. The dipper reversal mechanism is hinged between the dipper and the rack, and is also hinged with the dipper rod swinging mechanism. The mechanical electric excavation mechanism can effectively solve the problems of complex structure, oil leakage, limited workplaces and the like of a hydraulic excavator, reduces the weight of the arm and improves the stress of each rod because three servo motors are all arranged on the rack, can flexibly finish various complex actions, and can be used for ordinary occasions as well as the special occasions of high altitude anoxia, undermines and the like.

Description

technical field [0001] The invention relates to a construction machine, in particular to a mechanical electric excavating mechanism. Background technique [0002] An excavator is an important construction machine that uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to stockyards. It is widely used in industry, transportation, energy, farmland transformation, and mine excavation. And in modern military engineering, it is one of the most important construction machinery in the field of engineering construction. [0003] So far, there are mainly two types of excavators: mechanical and hydraulic. The mechanical excavator uses mechanical transmission parts to realize the excavation action, which has the advantages of being strong and durable, but the traditional single-degree-of-freedom mechanical excavator cannot complete complex actions. Even if it is only used for mining, it often encounters ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a mechanical electric excavating mechanism, which can not only overcome the shortcomings of traditional mechanical excavators such as simple movement and difficult control of excavation speed, but also overcome the high precision requirements of the hydraulic system components of hydraulic excavators, complex structures, and easy Disadvantages such as oil leakage
