Description
Technical field
The present invention relates to coal mining mechanical field, particularly a kind of stabilizing energy-saving type coal-winning machine with exterior protection.
Background technology
In recent years, coal-cutting machinery industry development in China's is swift and violent, has ended national coal-cutting machinery manufacturing enterprise in 2010 up to
24, for volume of production and marketing about more than 800, production capacity reaches 1500 or so.From the point of view of domestic coal machine competition situation, China's coal machine and manufactures enterprise
Industry is interfereed with the development slowly by the planned economy era, and not only technical merit is relatively low, and product is single.Although skill upgrading is very in recent years
It hurry up, but compared with external coal machine giant, the reliability and stability of China's coal mining machinery equipment complete machine are not still strong, lack industry
Top brand, there is a segment difference away from open coal mine digging with international most advanced level in financial strength and R＆D capability
It is larger with external gap in terms of the production of equipment, greatly without being the current real picture of China's coal machine profession by force.
Coal-winning machine is one of visual plant for realizing coal production mechanization and modernization, and mechanical coal mining can mitigate body
Power work, security is improved, reach high yield, high efficiency, low consumed purpose.
When being operated for coal-winning machine, the cooling of critical piece and the dedusting of working face are entered frequently with spray cooling system
Row is realized, but conventional spray cooling system and non-selectivity water spray, and it is comprehensive use water, section components are temporarily unnecessary
When cooling, cold water also still acts on, and causes the waste that water resource is unnecessary.
Existing coal-winning machine cooling device can not meet to use needs at present, easily be vibrated in coal mining machine operation,
It can loosen cooling device and the tie point of external water pipe, so as to which leak easily occur, it is necessary to often go to overhaul, and then using very
It is unreliable, at the same it is long-term use of when cooling device be fixed easily it is unstable, so as to influence the transmission of gear.Meanwhile the process of coal mining
In, the cinder to drop is pounded in control unit, the parts in fragile control unit.
The content of the invention
The purpose of this part is to summarize some aspects of embodiments of the invention and briefly introduce some preferably to implement
Example.It may do a little simplified or be omitted to avoid making our department in this part and the description of the present application summary and denomination of invention
Point, the purpose of specification digest and denomination of invention obscure, and this simplification or omit and cannot be used for limiting the scope of the present invention.
In view of problem present in above-mentioned and/or existing coal-winning machine, it is proposed that the present invention.
Therefore, the one of purpose of the present invention is to provide a kind of stabilizing energy-saving type coal-winning machine with exterior protection, its
With exterior protection function, save the water resource needed for operation, and can anti-antipriming pipe loosening is connected with heat exchanging piece.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of stabilizing energy-saving with exterior protection
Type coal-winning machine, it includes cut unit, including the first cutting units and the second cutting units, and both are symmetrical structure, and are set respectively
