Abstract

The embodiment of the invention discloses a telescopic shovel plate mechanism and a heading machine. The telescopic shovel plate mechanism comprises a main shovel plate (1), a first side shovel plate (2), a second side shovel plate (3), a first telescopic shovel plate (4) and / or a second telescopic shovel plate (5), wherein the first side shovel plate (2) is arranged on one side of the main shovel plate (1); the second side shovel plate (3) is arranged on the other side of the main shovel plate (1); the first telescopic shovel plate (4) is telescopically arranged on one side, far away from the main shovel plate (1), of the first side shovel plate (2) through a first telescopic driving piece (41); and / or the second telescopic shovel plate (5) is telescopically arranged on one side, far away from the main shovel plate (1), of the second side shovel plate (3) through a second telescopic driving piece (51). The shovel plates are widened and narrowed in a transverse telescopic mode of the telescopic shovel plates so as to adapt to roadways with different widths, the probability that materials are clamped can be reduced, the service life is prolonged, the occupied space is small in the transverse telescopic mode, and the roadway applicability of the shovel plates is improved.

Description

technical field [0001] The invention belongs to the technical field of miner mining, in particular to a telescopic shovel mechanism and a roadheader. Background technique [0002] With the development of the coal industry, roadheader loading shovels have been widely used for underground transportation in coal mines. However, with the continuous improvement of the information level and the development of the international market, the existing fixed-width scraper structure cannot fully meet the use requirements of different roadway widths. [0003] The traditional loading mechanism for roadheaders is a star-wheel type scraper device transportation type, which adopts a fixed-width structure in which the main scraper connects the left scraper and the right scraper to meet the needs of the mine roadway. When the roadway is mined and the mine side needs to mine a narrow roadway, the tunneling equipment cannot drive through it due to the limitation of the width of the shovel. The...
