Its main mechanism includes the following several portions: main machine frame, rear machine frame, cutting mechanism, scooping plate mechanism, conveying mechanism, dust-removing mechanism, traveling mechanism, driving mechanism, hydraulic mechanism, electric control circuit and stable mechanism. Said invention also provides the connection mode of all the above-mentioned portions, and also provides the working principle of said excavating machine and its operation method.

Description

technical field [0001] The invention relates to a coal mine underground continuous mining machine, which belongs to the technical field of design and manufacture of coal mining equipment in the coal mine. Background technique [0002] Continuous excavator is the main excavation equipment for roadway excavation in longwall working face and short-wall coal mining. It has the advantages of wide application range, flexible operation, fast relocation, low investment, continuous one-time completion of excavation, mining and transportation, etc., and is especially suitable for harsh environments. The mining of coal seams with geological conditions is a continuous excavation and mining machine with a wide range of applications, mechanization, and a high degree of automation. [0003] The continuous mining machine originated in the United States. The United States is also the country that uses the most continuous mining machines and is the most effective. 50% of its coal production i...

Problems solved by technology

[0004] The use of continuous excavators in my country was introduced in the late 1970s. It was mainly used exploratoryly in large coal mines in Shanxi, Shandong, Shaanxi, Heilongjiang and other provinces, and achieved good results. It is mainly used for longwall The rapid excavation of the roadway in the working face is fast and easy to relocate. It can also be used for short-walled room-and-pillar mining. The mine construction period is short, the coal output is fast, and the efficiency is high. However, the continuous excavation machines used in my country rely entirely on foreign imports, mainly Models from the United States, the United Kingdom, and Germany are mostly expensive, and it is difficult to fully adapt to the geological conditions of coal fields in my country during use. It is difficult to match the main components and vulnerable parts, the maintenance cycle is long, and the use and maintenance are expensive and difficult. Moreover, these imported equipment are inconsistent with my country's explosion-proof standards. At present, continuous mining machines are still a blank in scientific research in my country, and there are no complete domestic models.
