The invention discloses an assembly type coal mining machine atomizing nozzle. The assembly type coal mining machine atomizing nozzle comprises an atomizing nozzle shell, an assembly through hole is formed inside the atomizing nozzle shell in the axial direction, an atomizing nozzle inner core is installed in the assembly through hole in the internal axial direction in an embedding mode, the middle of the outer wall of the atomizing nozzle inner core is of a circular-truncated-cone-shaped structure, the two sides of the outer wall of the atomizing nozzle inner core are of cylindrical structures, the length of the atomizing nozzle inner core is equal to that of the atomizing nozzle shell, a positioning clamping plate comprises a clamping plate main body, an annular assembling hole and a handle groove hole are formed in the front end and the rear end of the clamping plate main body correspondingly, an assembling groove is connected into the annular assembling hole in a clamped mode, and the rear end of the positioning clamping plate extends out of the side wall of the atomizing nozzle shell. According to the assembly type coal mining machine atomizing nozzle, the atomizing nozzle inner core can be rapidly disassembled to be replaced under the condition that the atomizing nozzle shell on a atomizing system is not disassembled, assembly is easy, and use is more convenient.
Description
technical field [0001] The invention relates to the technical field of coal shearers, in particular to an atomizing nozzle of an assembled coal shearer. Background technique [0002] The shearer is one of the main equipment of the fully mechanized mining equipment. The shearer is developed from the shearer. The shearer is a large and complex system integrating machinery, electricity and hydraulics. The working environment is harsh. Failure will lead to the interruption of the entire coal mining work, resulting in huge economic losses. The shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, achieve high output, For the purpose of high efficiency and low consumption, in the long-wall coal mining face, the coal is broken down from the coal body by the working mechanism (coal breaking) and loaded into the working face conveyor (coal loading).
