The Design of Sheare Cutting Unit
Abstract
Sheare is an important equipment for excavation. It is one of the important facilities for the mechanization and modernization of coal-mining production. Hence it has important effects on the improvement of excavation efficiency. Presently the design technologies of sheares have developed relatively perfect. When comparing with abroad, however, the technology of this area is still behindhand.
Basing on assimilating the experience of people has worked in this area, this design, schemes out High-power sheare which is suitable for medium thickness seam. It does innovatory design on the cutting unit of shears by resorting to disposal symmetry of Mightiness Worn Roller, which improves the cutting effect and longevity. At the same time it reduces the wastage of truncation straight and customers’ cost. As to Machine driven system, its transmission resorts to spur gear and planetary wheel. Hence the transmission efficiency is improved and its installation and maintenance are easier. Two of the departments of crop are driven by two separate 250kw- electromotors. The modulation range of electromotors’ capacity in the departments of crop is large, which is ranging from 150kw to 300kw. Through the modulation of the electromotors’ capacity, the one machine-multi-type style can be carried out. The departments of crop resort to globe certificate floating structure, whose carrying capacity is large and reducing the structure measure. The applications of ply rockerarm increase the coal’s transit space and improve the coal’s load effect. The bottom taking
quantity is large. This design of sheare has the features as follows:
The excavation efficiency is high; the production of types can be different according to different coal quality. The adaptability in marketing is strong.
Key Words Sheare Mightiness Worn Roller cutting unit ply rockerarm transition system
