Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0023] Such as figure 1 Shown is a structural schematic diagram of a support device for coal and rock identification of a coal mining machine, including: a base 1, a transverse telescopic mechanism installed on the base 1, and a longitudinal telescopic end of the transverse telescopic mechanism. A telescopic mechanism, a support base 14 mounted on the longitudinal telescopic end of the longitudinal telescopic mechanism, and an antenna protection box 9 mounted on the support base 14, wherein the transverse telescopic end can be telescoped transversely, the The longitudinal expansion and contraction mechanism is capable of longitudinal expansion and contraction.

[0024] Specifically, the base 1 of the supporting device is fixed on the frame of the shearer 15, and then a transmitting antenna and a receiving antenna are installed in the antenna protection...

Abstract

The invention discloses a supporting device for recognizing coal rocks of a coal cutter, a coal cutting system and a coal cutting method. The supporting device comprises a base, a transverse telescopic mechanism mounted on the base, a vertical telescopic mechanism mounted on the transverse telescopic end of the transverse telescopic mechanism, a supporting seat mounted on the vertical telescopic end of the vertical telescopic mechanism and an antenna protecting box body mounted on the supporting seat, wherein the transverse telescopic end can stretch transversely and the vertical telescopic mechanism can stretch vertically. According to the antenna protecting box body, an emitting antenna and a receiving antenna of the coal rock recognizing system can be hidden in the antenna protecting box body of the supporting device, so that the antennas are protected well. The antenna protecting box body can move along with the coal cutter, so that the necessity of arranging coal cutters on a hydraulic bracket is avoided, and the mining cost is saved.

Description

Technical field [0001] The invention relates to the related technical field of coal mines, in particular to a supporting device for coal and rock identification of a coal mining machine, a coal mining system and a coal mining method. Background technique [0002] At present, in the process of underground coal mining, the shearer needs to identify the coal and rock, and control the shearer drum to automatically adjust the height and position according to the identification result in order to cut coal and avoid rocks correctly. Coal and rock identification mostly use geophysical methods, such as memory intelligent program control, vibration spectrum analysis, natural gamma rays, radioactive isotopes, noise infrared and radar detection. The realization of the above-mentioned geophysical prospecting method requires not only corresponding detection devices, but also corresponding supporting devices to carry, support and protect the detection devices, and thereby prevent the collision ...
