Problems solved by technology
[0003] The coal clearance height of the shearer refers to the distance between the coal shearer and the transport device. The coal clearance height of the existing shearer is mostly fixed, which cannot be adjusted according to different coal mining requirements, resulting in a decrease in coal mining efficiency. Decrease, increase in coal mining cost

The invention provides an ultra-long working face coal mining machine with adjustable coal passing height. The ultra-long working face coal mining machine comprises a rocker arm; the coal mining device is rotationally arranged on the rocker arm; the first driving part is arranged on the rocker arm, the first driving part is in transmission connection with the coal mining device, and the first driving part drives the coal mining device to rotate; the transporting device is movably arranged on the rocker arm; and the third driving part is arranged on the rocker arm, the third driving part is in transmission connection with the transportation device, and the third driving part drives the transportation device to move relative to the coal mining device in the vertical direction. Compared with the prior art, the coal mining device has the advantages that the transportation device is driven by the third driving part to ascend and descend so as to be close to or far away from the coal mining device; the coal passing height is adjusted, different coal mining requirements are met, the coal mining efficiency is improved, and the coal mining cost is reduced.
Description
technical field [0001] The present application relates to the technical field of coal shearers, in particular to an ultra-long working face coal shearer with adjustable coal passing height. Background technique [0002] The coal shearer evolved from the coal cutter. It is a large-scale equipment integrating machinery, electricity and hydraulic pressure. As one of the main equipment of the fully mechanized mining equipment, it can reduce labor costs and improve coal mining safety. , to achieve the purpose of high output, high efficiency and low consumption. [0003] The coal clearance height of the shearer refers to the distance between the coal shearer and the transport device. The coal clearance height of the existing shearer is mostly fixed and cannot be adjusted according to different coal mining requirements, resulting in a decrease in coal mining efficiency. Decrease and increase of coal mining cost. Contents of the invention [0004] This application aims to solve ...
