Movable-arm and bucket-arm telescopic mechanical excavating mechanism controlled through crank block

Abstract

The invention discloses a movable-arm and bucket-arm telescopic mechanical excavating mechanism controlled through a crank block. The movable-arm and bucket-arm telescopic mechanical excavating mechanism comprises frames, a bucket, a bucket overturn component, a bucket lifting component, a movable-arm swinging component, a movable-arm telescopic component and a bucket-arm telescopic component. The excavating mechanism features in adjusting excavating radius and excavating depth, and the excavating radius can be enlarged and / or the excavating depth can be increased under the premise of not moving the body of the excavating mechanism, so that the excavating mechanism can have tasks best completed under certain conditions (such as high-altitude rescue, building dismantling, cleanup of riverbed silt and slope operation), multi-purpose is realized, and the excavating mechanism is timesaving and laborsaving.

Description

technical field [0001] The invention relates to an excavator, in particular to a mechanical excavating mechanism with a telescoping boom and a stick controlled by a crank slider. Background technique [0002] There are currently two types of excavators on the market, hydraulic excavators and mechanical excavators. Among them, hydraulic excavators use hydraulic oil as the medium for power transmission, which has poor starting performance and is prone to leakage due to wear and tear of internal components. There are many components involved, and the leaked hydraulic oil will cause environmental pollution, and at the same time, overheating and inability to work will occur; mechanical excavators mainly rely on wire ropes, gears, runners and connecting rods as the medium for power transmission, and can be used to a certain extent. Some shortcomings of improving hydraulic excavators, but the current mechanical excavators still have some problems, such as the inability to adjust th...

[0002] There are currently two types of excavators on the market, hydraulic excavators and mechanical excavators. Among them, hydraulic excavators use hydraulic oil as the medium for power transmission, which has poor starting performance and is prone to leakage due to wear and tear of internal components. There are many components involved, and the leaked hydraulic oil will cause environmental pollution, and at the same time, overheating and inability to work will occur; mechanical excavators mainly rely on wire ropes, gears, runners and connecting rods as the medium for power transmission, and can be used to a certain extent. Some shortcomings of improved hydraulic excavators, but the current mechanical excavators still have some problems, such as the inability to adjust the digging radius and digging depth, etc., thus limiting its scope of use
