Abstract

The invention discloses a pineapple head coal mining machine belonging to the technical field of coal mining machinery. It includes a traction part, a body part, and a cutting head; the traction part is connected to the body part, and the body part is connected to and drives the cutting head; the body part also includes a cutting height adjustment mechanism and a cutting width adjustment mechanism. The mechanism and the cutting width adjusting mechanism are respectively connected with the cutting head. The invention has the characteristics of short fuselage, strong detachability of building blocks, adjustable coal mining height, adjustable coal mining width, large coal mining area, high coal mining efficiency and strong adaptability; The wide mechanism is simple and reliable, which can meet the needs of coal seam mining where the width of the working face changes. The cutting heads on both sides of the fuselage move relatively independently and do not affect each other.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery in coal mines, and in particular relates to a pineapple head shearer which is suitable for inclined coal seams and whose width of the coal mining face varies. technical background [0002] Coal is an important part of my country's national energy strategy. my country's Xinjiang region has abundant coal resources. The equipment level of coal mining machinery is one of the important symbols of the technical level of coal mines. With the development of coal mining machinery, it is necessary to continuously develop new coal mining machines to meet the needs of different coal seam geological conditions. The selection of coal mining machinery depends on the occurrence conditions of the coal seam. [0003] The storage of steep coal seams in my country accounts for about 14.05% of the total coal storage. These coal seams are mainly distributed in Sichuan, Xinjiang, Guangdong, Fujian, Gans...
