Problems solved by technology

Due to the low coal seam, the conventional roadheader has a high fuselage (≥1.4 meters) and a large volume, so it cannot be used in small and medium roadways; some thin coal seams adopt room-and-pillar mining, which has a low degree of mechanization, and blast mining is dangerous, seriously Affected the production and benefits of coal mines

Abstract

The invention relates to a scrub light tunneling machine for coal mine dislodging digging, comprising a self-propelled caterpillar belt chassis (1), a hoeing machine (2) mounted on the self-propelled caterpillar belt chassis (1), a cutting slewing equipment (4) fixed on front of the self-propelled caterpillar belt chassis (1), cutting arm (3) mounted on head of the cutting slewing equipment (4), oil tank, electrical control box (5) and a pump transmission box suspended on outer traveling holder of the self-propelled caterpillar belt chassis (1). A elongated high-power motor (6) is employed for the cutting slewing equipment (4). The invention is characterized in that it is adapted for tunnel digging or chamber-column mining-hoeing of low coal seam below 1.2 meters, working efficiency of the low coal seam is improved by mining mechanization.

Description

1. Technical field: [0001] The invention relates to a short and light roadheader used for mining and driving in coal mines and other mines. 2. Background technology: [0002] With the continuous development of coal mines, there are more and more coal seams of about 1.2 meters. Due to the low coal seam, the conventional roadheader has a high fuselage (≥1.4 meters) and a large volume, so it cannot be used in small and medium roadways; some thin coal seams adopt room-and-pillar mining, which has a low degree of mechanization, and blast mining is dangerous, seriously Affected the production and benefits of coal mines. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a short and light-duty roadheader, which is suitable for roadway excavation or room-and-pillar mining and stripping operations in thin coal seams below 1.2 meters, so as to improve the mechanization of thin coal seam mining and improve operating efficiency. [0004] In ord...
