Coal mine drum shearer

Abstract

The invention belongs to the technical field of coal cutters, and particularly relates to a coal mine drum-type coal cutter. The coal mine drum-type coal cutter comprises a coal cutter body, a drum installed on the coal cutter body, and a first crushing head installed on the surface of the drum; one side of the drum is fixedly connected with a first connection layer through bolts, the side, away from the drum, of the first connection layer is provided with a second connection layer, and second crushing heads are annularly distributed on the outside of the first connection layer and the outsideof the second connection layer; the coal cutter body is moved to the proper position, then, the relative distance between the first connection layer and the second connection layer is adjusted to a certain extent under the adjusting and fixing effects of a rotary knob according to the specific situation of the coal mine layer plane thickness, accordingly, when the drum is rotated, the coal mine is sufficiently exploited through cooperation of the second crushing heads on the first connection layer and the second connection layer as well as convex blocks and crushing bocks on one side of the second connection layer, and the problem that an original coal mine drum-type coal cutter cannot exploit the coal mine layer on the plane to a great extent is solved.

Description

technical field [0001] The invention belongs to the technical field of coal mining machines, and in particular relates to a coal mining roller mining machine. Background technique [0002] The coal mining machine is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. The coal mining machine is to realize the mechanization and One of the important modern equipment, mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. Coal shearers are divided into four types: sawing type, planing type, drilling type and milling type. Type: The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh.

[0002] The coal mining machine is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. The coal mining machine is to realize the mechanization and One of the important modern equipment, mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. Coal shearers are divided into four types: sawing type, planing type, drilling type and milling type. Type: The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. With the development of the coal industry, The shearer has more and more functions, and its own structure and composition are more and more complex, so the reasons for the failure are also complicated. The double-drum shearer combines the successful experience of thin coal seam shearers at home and abroad, and is aimed at A new type of high-power thin coal seam shearer designed for specific national conditions. In the process of using the coal mine drum shearer, it often uses the cooperation of the drum and the crushing head on the surface to mine the coal mine, but in the process of mining In the existing coal mine drum shearer, most of the drums are integrated components, which cannot be extended and adjusted to a certain length, and the coal seam on the plane cannot be mined to a good extent, and at the position of the crushing head It is impossible to adjust multiple angles according to the specific conditions of the coal mine surface, which makes the existing coal mine drum shearer have certain limitations in use
