Abstract

The invention discloses a three-roller coal cutter, pertaining to the multi-roller coal cutter field. The coal cutter of the invention is additionally provided with a sectional cutting roller on a same coal mining workface at the middle on the basis of a two-roller coal cutter. As three sectional cutting rollers simultaneity work on the coal mining workface, the roller can be designed into the one with smaller diameter under the situation of the same coal mining height so as to make obvious progress on aspects such as manufacturing technology and cost, etc. Meanwhile, due to a shortened rocker arm, the three-roller coal cutter has more flexibility on the aspect of adaption to mining height.

Description

technical field [0001] The invention relates to a drum coal mining machine, in particular to a multi-drum coal mining machine. Background technique [0002] Background: At present, coal shearers in my country and the world are developing towards high power and high mining height, and the power of a single machine has reached 1600 kilowatts. Existing drum shearer or single drum or double drum. Its structure is mainly composed of cutting part (single drum or double drum), electric control box, hydraulic unit, internal and external traction part, rocker arm, bottom bracket, accessory devices and so on. With the improvement of equipment manufacturing technology, coal shearers are generally developing in the direction of high power, automation and high reliability. At present, the shearer of medium-thick coal seam technology is relatively mature and stable. Due to the improvement of equipment manufacturing technology, the change of coal mining process has also been brought abou...
