Description
The utility model relates to the plant equipment that cuts coal, and is specially adapted to a kind of portable small-sized novel device that Township Coal Mine is mined and tunneled.
China's middle and small scale coal mine, Township Coal Mine generally adopt the coal-mining method of drilling and blasting at present, but charcoal yield is low, and are absolutely unsafe.Prior art discloses a kind of coal body digging machine (CN2054074U), when the driving coal road, dig out the dark moat of twice simultaneously in the rib both sides, but mainly there is following weak point in this coal body digging machine:
1, narrow to height, the width adjustable range of work plane.This digging machine wants two statures, smatterer to carry out work simultaneously for the each grooving of each work plane, can't cutter relieving to rock (pricker stone) interlayer, can not adapt to the various getting working face changes of section of Township Coal Mine.
2, can not cut a hole coal trench bottom translot.
3, cutter is fragile, and application life is short, cutter is not had safeguard measures such as cooling, buffering, and the sparking phenomenon takes place when being not difficult to avoid cutting, and hidden danger is arranged.
4, the shared dynamical system of cutting and lifting, both speed are difficult to coupling.Because of the hardness in coal seam changes, a shared dynamical system causes damage of facilities easily.
5, blow out before, equipment is difficult for moving away from work plane, the influence operation etc. of producing coal.
The present utility model purpose overcomes the prior art weak point, designs a kind of simple to operate, safe and reliable, light mining coal body mortising slot machine of explosion-proof type of carrying dismounting that Township Coal Mine is used that be particularly suitable for.
The object of the invention is achieved by the following technical solution.
