Abstract

The invention relates to the technical field of coal crushing equipment, in particular to efficient coal multi-stage crushing equipment for coal mine exploitation. A first rotating shaft is driven bya servo motor to rotate, on one hand, the first rotating shaft drives a second d rotating shaft to rotate through a transmission belt, crushing cutters interact, and coal in a feeding hopper is crushed; on the other hand, the first rotating shaft directly drives a grinding end to grind coal falling into a grinding channel through a feeding pipe, and therefore multi-stage crushing is achieved, andthe crushing effect and efficiency are improved; the first rotating shaft further drives a third rotating shaft to rotate through the transmission belt, a moving block moves up and down in the axial direction, a baffle is driven to move, the feeding pipe is intermittently opened or sealed, and intermittent feeding is achieved; and a push-pull assembly is arranged, a cylinder cam rotates along withthe first rotating shaft, a wedge block is driven by a connecting rod to move up and down, a push-pull rod drives a blocking plate to work in cooperation with a spring, and blocking and material pushing are completed.

Description

technical field [0001] The invention relates to the technical field of coal material crushing equipment, in particular to a high-efficiency multi-stage coal material crushing equipment for coal mine development. Background technique [0002] Mineral resources are the product of the long-term formation, development and evolution of the earth's crust, and are formed by the accumulation of natural minerals under certain geological conditions and through certain geological processes. Different geological processes can form different types of minerals. According to the geological process of forming mineral resources and the different sources of energy and materials, the geological process of forming mineral resources, that is, mineralization is generally divided into endogenous mineralization, exogenous mineralization, metamorphic mineralization and superimposed mineralization. Whether minerals can be formed in a region, how much they are formed, and whether they are good or bad...
