Intermittent feeding type coal briquette coarse crushing device for coal mine mining

Abstract

The invention discloses an intermittent feeding type coal briquette coarse crushing device for coal mine mining. The intermittent feeding type coal briquette coarse crushing device comprises a bearingplate. A crushing box is fixedly installed on the bearing plate vertically. A rotating cover plate is arranged on the top of the crushing box in a rotating manner. A drive motor is fixedly installedon the outer wall of the left side of the crushing box through a support. The left end of a pulling rope penetrates the interior of a resetting spring and is fixed to the upper end of a sliding baffle. A guide sliding groove is horizontally formed in the side wall of a crushing pressing plate. A clamping block embedded in the guide sliding groove in a sliding manner is fixedly installed on the inner side wall of the sliding support. According to the intermittent feeding type coal briquette coarse crushing device, by means of rotating of a crushing roller, the extruding and crushing effect on coal briquettes is achieved, by means of vertical reciprocating motion of the sliding baffle, the coal briquettes on a material guide oblique plate enter a screening plate intermittently, the coal briquettes falling on the screening plate are extruded and rubbed repeatedly through the crushing pressing disc, excessive centralizing of the coal briquettes is avoided, the rubbing and crushing effectsof the crushing pressing disc are improved greatly, the coal briquettes are crushed more fully, the screening plate has a screening function, and it is ensured that the coal briquettes on the screening plate are refined fully.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to an intermittent feeding type coal block coarse crushing device for mining. Background technique [0002] Coal is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. The sum of carbon, hydrogen and oxygen accounts for more than 95% of the organic matter. It is a very important energy source and an important raw material for metallurgy and chemical industries. There are several classifications of lignite, bituminous coal, anthracite, and semi-anthracite. The famous writer Zhu Ziqing once wrote a poem titled coal, giving it a unique symbolic meaning. As of 2011, China is the country with the largest coal production in the world, with coal production of 3.24 billion tons, equivalent to 1.8004 billion tons of oil equivalent, accounting for 48.3% of the world; followed by the United States, accounting for 14.8% of world production; ra...

Problems solved by technology

[0003] Before the coal is processed, the coal needs to be coarsely crushed to realize the crushing and refinement of the larger coal. However, the current coarse coal crushing device has a poor crushing effect on the coal. During the crushing process, the coal Accumulation is easy to cause the reduction of crushing effect, and the crushing of coal blocks is not complete enough. Therefore, it is urgent to provide an intermittent feeding coal mine mining coal crushing device to improve the crushing effect of coal blocks.
