Embodiment Construction
[0032] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0033] Such as Figure 1-Figure 3 Shown, the present invention is a kind of lump coal cutting machine, comprises fuselage 18, and fuselage 18 is provided with the walking mechanism that walks along the coal mining face. The traveling mechanism in the present invention adopts a gear transmission mechanism, including a traction gear 13 arranged at the bottom of the fuselage 18 and a track 24 arranged below the fuselage 18 , and the traction gear 13 is meshed on the track 24 . When the present invention works, it is installed on the scraper machine 19 arranged along the coal mining face, and the track 24 is arranged on the scraper machine 19 .
[0034] The middle part of the fuselage 18 along the walking direction is provided with a guide hopper 15 and a crushing device 16 connected to the guide hopper 15. The guide hopper 15 is used to guide ...

The invention relates to a lump coal mining and cutting machine comprising a machine body, wherein a material guide hopper and a crushing device are arranged at the middle of the machine body; a first upper cutting part, a first lower cutting part and a first lateral cutting part are arranged at one side of the machine body, a first extrapolating device used for extruding the inner side of a coal layer outwards is arranged on the first lateral cutting part, a first loading mechanism is arranged below the first lateral cutting part, and the first loading mechanism is connected with the material guide hopper through a first conveying part; a second upper cutting part, a second lower cutting part and a second lateral cutting part are arranged at the other side of the machine body, a second extrapolating device used for extruding the inner side of the coal layer outwards is arranged on the second lateral cutting part, a second loading mechanism is arranged below the second lateral cutting part, and the second loading mechanism is connected with the material guide hopper through a second conveying part. The upper cutting parts, the lower cutting parts and the lateral cutting parts are respectively arranged at the two sides of the machine body of the lump coal mining and cutting machine along the walking direction, thereby capable of mining and cutting coal towards left and right sides along a coal mining working surface to exponentially improve the production efficiency.
Description
technical field [0001] The invention relates to a coal seam cutting machine, in particular to a lump coal cutting machine capable of mining lump coal. Background technique [0002] At present, the domestic industry and the public have a large demand for lump coal. The price of lump coal in the market is about twice that of crushed coal, and the economic benefits are huge. But the coal that the existing general-purpose shearer extracts is pulverized coal, can't extract lump coal. [0003] The applicant applied for on April 18, 2011, the patent number is: 201110095710.3, and the invention patent named lump coal cutting machine discloses a cutting machine that can extract lump coal, but this patent can only be used along the The coal mining work faces one direction of mining and cutting, and the production efficiency is low; in addition, this patent adopts a self-propelled walking mechanism, and the cost is relatively high. Contents of the invention [0004] Aiming at the p...
