Background technology
The quantity-produced wheel type loader of China, generally be applicable to big-and-middle-sized engineering construction, though that this wheel type loader has power is powerful, carrying capacity is big, the construction requirement that can adapt to the topographic condition of various more complicated, the structure that is adopted are special-purpose loader structure.But also exist tangible weak point: the general more complicated of structure, maintenance is inconvenient, and consume fuel is many, and running cost compared is higher.Though China has also developed some and has been applicable to the minitype wheeled loader that mini engineering is built at present, still productive costs is higher, and consumption of fuel is bigger, and loading height is generally lower.And under some working condition in real industrial and agricultural production, above-mentioned loader can not adapt to the needs of real work preferably, especially some load the units such as gravelstone material factory, building block brick field, paper mill, coal works of light materials, need aborning a kind of lighter, operation cost is lower and loading height is higher, use small sized loader tool easy to maintenance to replace traditional manual work, to reduce labour intensity, enhance productivity.Add that the general fund of these business units is not very abundant, so be sought after a kind of not only practical but also economic a kind of miniature energy-saving two wheel driving type low loaders.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, safe in utilization, easy to maintenance, easy and simple to handle, a kind of miniature energy-saving two wheel driving type low loaders that loading height is high, with low cost.
The purpose of this utility model is achieved in that a kind of miniature energy-saving two wheel driving type low loaders, it is by a kind of back axle of combination machine and driving, form jointly with the loader mechanism that combines with propons, these two parts connect by a jointed shaft, realize steering operation by turning to oil cylinder; The loading arm of loader mechanism, lifting hydraulic cylinder are connected by drift bolt on the support of both sides, by the cargo-carring lifting of flexible realization of lifting hydraulic cylinder; By connect to load crank arm and support between the loading and unloading of flexible realization goods of upset hydraulic actuating cylinder; Power system is provided by diesel motor, by engagement, the gear (12-2) and the engagement of engagement, gear (12-8) and the gear (12-6) of gear (12-3) and the engagement of gear (12-8) and gear (12-5) of change speed gear box inner gear (12-2), realize that respectively a reversing and a retaining, two keep off, three takeoff outputs that keep off with gear (12-4).
This utility model has certain novelty, be embodied in the applying date and do not have same invention or utility model in the past, at home and abroad published on the publication, public use is at home and abroad crossed or otherwise for known to the public, does not also have in the patent application document that same invention or utility model announced after Patent Office proposed to apply for and was documented in the applying date by other people.
This utility model also has certain creativeness, is embodied in before the applying date, and the general more complicated of loader structure that adopts is at present keeped in repair inconvenience both at home and abroad, and consume fuel is many, and running cost compared is higher.This utility model is utilized back axle and the driving by a kind of combination machine, forming jointly with the loader mechanism that combines with propons, is a kind of simple in structure, safe in utilization, easy to maintenance, easy and simple to handle, small-sized two wheel driving type loaders that loading height is high, with low cost.This invention is compared with the technology that loader adopted of general production application both at home and abroad at present, has outstanding substantive distinguishing features and obvious improvement.
The beneficial effects of the utility model are: simple in structure, safe in utilization, reliable, with low cost, maintenance, driving, easy to operate, its cost only is about 30% of a loading machine of the same type, is highly suitable for the discrete material loading operation of some small-sized coal works, paper mill, sandstone material factory, building block brick field.
