Embodiment Construction

[0015] Such as figure 1 As shown, the coal shearer coal-rock distribution recognition device using terahertz imaging technology includes a terahertz imaging coal-rock interface recognition sensor, a processor, a height-adjusting oil cylinder, a height-adjusting roller, and an alarm device. The output signal of the terahertz imaging coal-rock interface recognition sensor is sent to the processor, the processor outputs the signal to the height adjustment cylinder, the height adjustment oil cylinder outputs the signal to the height adjustment roller, or the processor outputs the signal to the alarm device. The processor memory has the parameters of the set cutting state (default coal cutting) of the drum at each cutting position. The terahertz imaging coal and rock distribution recognition sensor identifies the coal and rock distribution at each cutting position of the next cutting cycle of the shearer, and outputs the recognition result to the processor. Rock distribution reco...

Abstract

The invention discloses a coalcutter coal rock distribution recognition device and method adopting terahertz imaging technology. The device comprises a terahertz imaging coal rock recognition sensor, a processor, a heightening oil cylinder, a heightening roller and an alarm device; set cutting state parameters of the roller at each cutting position are stored in the processor; the terahertz imaging coal rock recognition sensor recognizes the coal rock distribution condition of a coalcutter at each cutting position in the next cutting cycle and outputs a recognition result to the processor; the processor processes and stores the recognition result according to a coal rock distribution recognition method, and a storage result serves as a basis at the processor outputs a signal to the heightening oil cylinder, the heightening roller or the alarm device at the corresponding position in the next cutting cycle. The coal rock distribution condition in the next cutting cycle is recognized in advance, a roller height is determined in advance and cutting into rock is avoided. A defect that only after roller cutting teeth cut into the rock, the rock cutting can be recognized under a memory coal rock cutting interface recognition technology is overcome.

Description

technical field [0001] The invention relates to a device and method for coal-rock interface recognition, in particular to a coal-rock distribution recognition device and method for a shearer using terahertz imaging technology, and belongs to the technical field of coal-rock interface recognition. Background technique [0002] Automatic recognition of coal-rock interface is the first problem encountered in realizing automatic height adjustment of shearer drum and automatic control of coal mining face. The purpose of identifying the coal-rock interface is to ensure that the drum cuts in the coal seam and prevent the drum picks from cutting into the rock in time to prevent accidents. At present, the coal-rock interface recognition technology of shearer has been developed to the stage of memory cutting coal-rock interface recognition. The technology features cutting state recognition sensors and processors. Before the automatic cutting cycle of the shearer, the technology uses...
