Abstract
A large-rigidity multi-connecting-rod controllable mechanical loading mechanism comprises a frame, a movable arm control branch chain and a bucket control branch chain. The movable arm control branch chain is controlled by a first drive rod to perform movable arm ascending or descending. The bucket control branch chain is controlled by a second drive rod to control turning of a bucket. By cooperation of the movable arm control branch chain and the bucket control branch chain, loading operation can be completed. Rods of the mechanical loading mechanism are connected through rotating pairs, and the defects that traditional total-hydraulic loading mechanisms containing moving pairs are high in manufacturing cost, poor in reliability, high in maintenance cost and the like are overcome. Compared with other controllable mechanical loading mechanisms, the loading mechanism is compact in structure, high in rigidity, and good in reliability and dynamic stability by using the novel structure with excellent kinematic and dynamic performance.

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 compactness, 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, drive loader mechanism operation to become possibility with mechanical drive mode.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 large many connecting rods of rigidity controllable mechanical formula loader mechanism, 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:
A kind of large many connecting rods of rigidity controllable mechanical formula loader mechanism, is comprised of frame, swing arm control side chain, scraper bowl control side chain.
