Spinning coal mining machine

Abstract

The invention relates to mining equipment, particular to a spinning coal mining machine and a method which are used for mining large-sized coal according to the brittle feature of coal by using a spinning mechanism to impact, vibrate and cut coal layers in a rotating way. The spinning coal mining machine comprises a spinning mechanism, a driving mechanism, a machine body and the like, wherein the spinning mechanism is mounted on the machine body; the driving mechanism drives the spinning mechanism to rotate; the spinning mechanism impacts and cuts coal layers; the walking process of the machine body progresses in the match with the depth that the spinning mechanism impacts and cuts the coal layers. If a rotation bush hammer of the spinning mechanism has impact overload during a complete impacting process, by the bending, shifting and the like of a chaining part, a coupling part and an axial buffer part of a rotation arm, the rotation bush hammer can pass smoothly and continuously spins quickly to impact and cut the coal layers to continue coal mining. By the equipment, coal spinning and surface cleaning can be completed synchronously. And the spinning coal mining machine has the advantages of high block material rate, low power consumption, simple structure, stable performance, large mining height range, safety and reliability and the like.

Description

technical field [0001] The invention relates to a mine mining equipment, in particular to a rotary impact shearer. Background technique [0002] The currently widely used mining equipment in mines is the shearer and the plow. Its working principle is milling type blanking, which determines that the crushing of this mining method is relatively large, especially in the state of compressive stress, which consumes a lot of energy and reduces productivity and block rate. At the same time, the crushing process also produces a large amount of dust, causing problems such as poor mining environment and potential safety hazards. To sum up, the currently commonly used drum shearer mainly has the following defects during use: (1) low lump material rate; (2) a lot of dust and harsh working environment; (3) the milling of the cutting part is relatively broken, and the power The consumption is large, there is a large amount of waste of resources, the work efficiency is low, and the cost ...

Problems solved by technology

Its working principle is milling blanking, which determines that the crushing of this mining method is relatively large, especially in the state of compressive stress, which consumes a lot of energy and reduces productivity and block rate

At the same time, the crushing process also produces a large amount of dust, which has caused problems such as bad mining environment and potential safety hazards.

To sum up, the currently commonly used drum shearer mainly has the following defects during use: (1) low lump material rate; (2) a lot of dust and harsh working environment; (3) the milling of the cutting part is relatively broken, and the power Large consumption, a lot of waste of resources, low work efficiency and high cost

The punching shearer avoids the disadvantages of the above-mentioned shearer, but the punching blade is not easy to make too wide, so the height of coal mining is limited, and the structure is more complex and bulky
