Cutting units 20, the second cutting units 30 are identical with the cut coal seam depth of the 3rd cutting units 40, especially give full play to the 3rd cutting units
The effect of 40 cut coal seam pit coal breakages, it is ensured that coal breakage cut it is deep, prevent the first cutting units 20, the second cutting units 30 cut it is deep excessive
Cause the slump of coal seam compression large area or the first cutting units 20, section the 3rd cutting units of deep too small increase of the second cutting units 30 two
Cutting strength during secondary cut.
The pick of the first cutting units 20 or the second cutting units 30 cut coal seam first is special, it is necessary to the broken coal ability of pick is strong
Be not the ability for being capable of the effective cut hard coal seam of low-power consumption, and the 3rd cutting units 40 mainly cut by the first cutting units 20 or
The coal seam pit of intensity decreases and cleaning coal cinder after the cut of second cutting units 30, without larger clipping force.Preferably, it is described
The pick density on the surface of taper on-bladed cylinder 51 of the first cutting units 20 and the second cutting units 30 is more than cylindrical on-bladed rolling
The density of cylinder surface pick, pick density is bigger, and cutting capacity is stronger, so that the first cutting units 20 and the second cutting units 30 can
Realize the effective cut hard coal seam of low-power consumption.
Preferably, the deceleration arm 44 is fixed on the middle part of fuselage body 10 by cutout and bolt.
Preferably, in order that the working depth of the 3rd cutting units 40 is adjustable, to adapt to the operation in the coal seam and complexity that rise and fall
Operating mode, lifts coal work efficiency, and deceleration arm 44 is high-power galianconism liftable structure.
Preferably, it is described in order that strengthening the effect that back taper extends out the coal cinder fluctuation of formula end plate 42 when coal-winning machine is walked forward
Back taper extends out the width that the width that pick is arranged on formula end plate 42 extends out the taper surface 43 of formula end plate 42 less than back taper.Big width
Taper surface 43 facilitates the fluctuation that back taper extends out coal cinder after the kerf of formula end plate 42.Checked through execute-in-place, cone of the present utility model
The effect of the taper of shape face 43 kerf exploitation at 15 ° preferably, coal disposably can be completely cleared up while operating efficiency is ensured
Wall.
The back taper extends out formula end plate 42 with diameter greater than the diameter of conical drum 50.The diameter of conical drum 50 is small, it is possible to achieve
The effective cut top of low-power, base plate hard coal seam, after base plate vicinity coal seam kerve is formed, the stress between coal seam is released, and
For coal cinder drops there is provided the more scope of freedom, cutting strength when back taper extends out formula 42 cut of end plate can be effectively reduced.
When using, as a example by illustrating coal mining operating mode, the conical drum 50 of the first cutting units 20 forms coal seam along base plate cut
Kerve, then the back taper of the 3rd cutting units 40 extend out pick on formula end plate 42 to coal seam followed by kerf, by back taper outside
Expansion formula end plate 42 is inserted into coal cinder fluctuation with cut impulsive force, and in the presence of cone extends out formula end plate 42 is pushed away fluctuation coal cinder
Enter scrapper conveyor, the pick on cylindrical on-bladed roller cuts the coal cinder of non-fluctuation and clears up coal cinder, it is ensured that whole pit cut
Roller 41 passes through rib；At the same time the coal seam near the roof cleaning of conical drum 50 of the second cutting units 30.
The first cutting units 20, the second cutting units 30 and the lateral arrangement of the 3rd cutting units 40 be in rib side in this process, and
One cutting units 20 and the second cutting units 30 carry out lift adjustment highly by fuselage oil cylinder 42, disclosure satisfy that maximum mining height and minimum
The requirement of planted agent, the pick of conical drum 50 is directly arranged at the surface of taper on-bladed cylinder 51, eliminates end plate and blade, greatly
Helix drum cut diameter is reduced greatly, cutting resistance is reduced, and the anterior design of taper on-bladed cylinder 51 is tapered, this
Sample further reduces cutting resistance, so as to reach do not put vibrations big gun in the case of mine purpose, reduce power consumption and
Cost, improves operating efficiency and production security.The leading cut bottom of conical drum 50 of the first cutting units 20, coal seam
Between stress significantly discharged, and for coal cinder drops there is provided the more scope of freedom, effectively reduce the 3rd cutting units
40 back taper extends out cutting strength of the formula end plate 42 in secondary cut, reduces cut power consumption, and back taper extends out formula end plate 42
Pick carries out kerf fluctuation coal breakage, will not fully crush coal cinder, effectively increases lump coal particle diameter, lump coal rate, reduces pick and damages
Amount and dust yield；The coal seam of the roof cleaning of the second cutting units 30, it is ensured that whole equipment is pushed ahead.In back production second section
Portion 30 is cut along base plate cut coal seam kerve, the coal seam of the roof cleaning of the first cutting units 20, three cooperates, be capable of achieving once to adopt
Overall height bidirectional cutting, first kerf is carried out to coal seam and is risen again layering coal breakage, and the speed of travel is relatively fast, can improve coal mining efficiency,
And the low-power consumption exploitation in hard coal seam can be realized.
