Abstract
The invention relates to a high-load capacity nine-lever and two-freedom degree mechanical loading mechanism, which comprises a machine frame, a movable arm control branched chain and a bucket control branched chain, wherein the movable arm control branched chain is controlled by a first driving lever and is used for elevating a movable arm; the bucket control branched chain is controlled by a second driving lever and is used for turning a bucket. The mechanical loading mechanism can complete loading and unloading operation by means of the interaction of the movable arm elevating branched chain and the bucket control branched chain. According to the mechanical loading mechanism, all the levers are connected through revolute pairs, and thereby the defects of high cost, low reliability, high maintenance cost and the like of the conventional full hydraulic loading mechanism with sliding pairs are overcome. Moreover, compared with other controllable loading mechanisms, the mechanical loading mechanism has the advantages of compact structure, high rigidity, and novel structure with superior kinematic and dynamic performance, and thereby the loading mechanism is higher in reliability and dynamic stability.

Background technology
Loader is a kind of restoration in earth-rock construction machinery that is widely used in the construction projects such as road, harbour, mine, railway, and it is mainly used in the loose unpacked materials such as shovel dress soil, sandstone, also can dig operation to the slight shovel of the works such as ore, pan soil.Change that kind of different auxiliary working apparatus also can be bulldozed, the handling operation of lifting and unclassified stores.Loader is the engineering machinery being most widely used, and along with socioeconomic development, loader is more and more in the application of the occasions such as Municipal engineering, garbage-cleaning, construction work.Existing loader is mainly comprised of swing arm lifting mechanism and scraper bowl switching mechanism two parts, by boom cylinder and bucket cylinder, control the action that fulfils assignment respectively, although hydraulic system structure is compact, but hydraulic system is subject to oil overheating impact, mechanical efficiency is low, transmission stability is poor, and Hydraulic System Reliability is poor, maintenance, maintenance complexity and cost are higher.
Along with the development of theory of mechanisms and electromechanical integration, with mechanical drive mode, drive loader mechanism operation to become possibility.Machinery driving efficiency is high, and existing electromechanical integration technology can overcome machine driving and easily transships the shortcomings such as destruction.But existing multiple degrees of freedom controllable type loader mechanism, mostly just existing hydraulic loader structure is carried out to simple modifications, utilize two linkages to replace the hydraulic system in hydraulic loader structure, the consideration of shortage to rod member transmission and hydraulic cylinder transmission dynamic property difference, causes mechanism's poor rigidity, and anti-overload ability is little, the shortcomings such as kinematics and dynamic performance are poor, be difficult to meet actual job needs, although solved the some shortcomings that hydraulic system exists, be difficult to be applicable to loader design and produce.
Summary of the invention
The problem that the object of the invention is to prior art existence provides a kind of high load capability nine bar two-freedom mechanical type loader mechanisms, guaranteeing to meet under traditional loader job requirements and linkage prerequisite simple in structure, not only avoid existing fluid pressure type loader poor reliability, the shortcomings such as transmission efficiency is low, and guarantee that this mechanical type loader mechanism has kinematics, dynamic performance is good, the advantages such as the rigidity of structure is large, and anti-overload ability is strong.
The present invention achieves the above object by technical scheme once:
High load capability nine bar two-freedom mechanical type loader mechanisms, are controlled side chain and are formed by frame, swing arm control side chain, scraper bowl.
