Four-drum shearer with capability of full-seam mining by layered cutting and mining

Abstract

The invention belongs to the technical field of coal mining and discloses a four-drum shearer with the capability of full-seam mining by layered cutting and mining, which is abbreviated as a layered-mining four-drum shearer. The shearer comprises a body, a left cutting part and a right cutting part, wherein the shearer body comprises a middle box, a left walking part and a right walking part; theleft cutting part is connected to the left walking part; the right cutting part is connected to the right walking part; the end, away from the right walking part, of the left walking part is rotationally connected with the left cutting part; the left cutting part is formed by a left rocker arm, a left-handed drum I, a right-handed drum I, a rotating arm I and the like; the end, away from the leftwalking part, of the right walking part is rotationally connected with the right cutting part; and the right cutting part comprises a right rocker arm, a left-handed drum II, a right-handed drum II, arotating arm II and the like. According to the four-drum shearer, under the same installed power, the mining height range is increased, the manufacturing cost is reduced, and the mining efficiency isgreatly increased; layered mining reduces the risk of rib spalling; the height of the shearer body is reduced, operation is facilitated, and the stability of the whole machine is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, and in particular relates to a full-height four-drum shearer for single-stage cutting mining. Background technique [0002] Shearer is one of the important equipment to realize the comprehensive mechanized mining of coal mine. It is a must for safe, economical and efficient coal mine production. Shearer is divided into sawing type, planing type, drilling type and milling type. It is a large and complex equipment integrating mechanical, electrical and hydraulic transmission, and is the core equipment of fully mechanized coal mining face. With the development of fully-mechanized mining face technology in coal mines, many new issues have been proposed for shearers, especially for the mining of medium-thick and above coal seams, hard coal seams, and soft coal seams. The invention focuses on the technical requirements of coal mining machines for mining medium-thick and above-thick coal...
