Parasitic mechanism type space-controllable excavating mechanism

Abstract

The invention discloses a parasitic mechanism type space-controllable excavating mechanism. A power rolling wheel of a three-dimensional rotation arm mechanism of the excavating mechanism rolls on thewhole semi-spherical surface of the interior of a base, so that a rotation arm ball rod achieves spatial rotation through a rotation arm ball body, and accordingly, a bucket rod and a bucket are driven to achieve spatial rotation. A parasitic mechanism part dives a crank to rotate through rotating of a first motor, so that a second motor frame plate connected with a seven connection rod does reciprocating motion along the rotation arm ball rod, and accordingly, a first spring and a second spring are driven to do reciprocating motion along the rotation arm ball rod; the bucket rod is rotated up and down through a middle connection rod, a second motor and a third motor drives the first spring and the second spring to rotate in the reverse direction through a reduction gear; and the bucket rod is rotated leftwards and rightwards through the middle connection rod, and the working space of the bucket is increased. A host mechanism and a parasitic mechanism can separately control or cooperatively control motion of the bucket, so that motion of the bucket is more stable, the situation that one of the control mechanisms breaks down, and operating is stopped is avoided, in addition, the excavating force is large, and the stress effect is good.

Description

Technical field [0001] The invention relates to the field of mechanical engineering, in particular to a parasitic mechanism type space controllable excavating mechanism. Background technique [0002] Excavator is a common excavating machine, mainly used for various earthwork construction, various types and functions of excavators, widely used in industrial and civil construction, transportation, water conservancy projects, farmland transformation, mining, and modern military In the mechanized construction of engineering and other industries, hydraulic excavators are currently the most widely used type of excavators, but the hydraulic system has high manufacturing costs, is prone to problems such as oil leakage, and cannot be used normally in low temperature environments. These are hydraulic excavators. The long-standing thorny problem of the machine. [0003] With the development of electronic control technology and the improvement of controllable technology, the controllable mech...

Problems solved by technology

[0004] The purpose of the present invention is to provide a parasitic mechanism-type space controllable excavating mechanism, which not only has the advantages of large working space, large digging force and good force bearing of the traditional hydraulic mechanism, but also overcomes the high maintenance cost and high manufacturing precision of the traditional hydraulic excavator , the problem of insufficient responsiveness and the problem that the electronically controlled excavator with only one control system in the existing design cannot be used normally in the event of a failure
