Problems solved by technology

[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. Improve some shortcomings of hydraulic excavators, but mechanical excavators also have relatively single application occasions due to structural problems, and cannot meet some special working conditions

Embodiment Construction

[0014] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0015] refer to figure 1 , which corresponds to a structural schematic diagram of a mechanical arm telescopic excavation mechanism that can expand the excavation depth in a preferred embodiment of the present invention. The excavation mechanism includes a plurality of motors (not shown), a frame 100, a bucket 16, a bucket Overturn assembly, bucket lifting assembly, boom swing assembly and telescopic assembly, wherein, the frame 100 is used for stabilizing the bucket overturn assembly, bucket lifting assembly and boom swing assembly; bucket 16 is the main work piece, used for shovel or excavate muck; the bucket turning assembly is mainly used to control the bucket 16 to turn inwards or outwards, so that the bucket 16 picks and places the muck; the bucket lifting assembly is mainly used to control the...

Abstract

The invention discloses a bucket rod telescopic excavating mechanism capable of expanding the excavation depth through control of a crank sliding block. The mechanism comprises a rack, a bucket, a bucket turnover assembly, a bucket lifting assembly, a movable arm swing assembly and a telescopic assembly. The excavating mechanism is reasonable in structure and multifunctional and has the turnover and lifting function of the bucket, the swing function of movable arms, and the function of adjusting the excavating depth; and particularly, for the excavating depth adjusting function, on the premise that an excavator body is not moved, the excavating depth can be increased, and the excavating mechanism can complete the basic function of an excavator and can better complete tasks under some conditions (such as sludge cleaning work and slope work of a river bed); and the aims that one machine has multiple functions, and time and labor are saved are achieved.

Description

technical field [0001] The invention relates to an excavator, in particular to an arm telescopic excavating mechanism controlled by a crank slider to expand the excavation depth. 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 the hydraulic excavator have been improved, but the mechanical excavator also has a relatively single application due to its struc...
