Description

Rocker arm of coal mining machine with high lump coal rate

Technical field

The utility model belongs to the coal excavation apparatus technical field, relates to a kind of coal-winning machine, relates in particular to a kind of rocker arm of coal mining machine with high lump coal rate.

Background technology

China's girdle complex geologic conditions, the work plane tomography is many, dirt band hardness is large.In order to make low seam mining machinery have high reliability, low seam mining machinery is more and more to high-power low seam mining machinery development.The low seam mining machinery fuselage is short, and space is little, and along with the power that transmits and the increase of moment of torsion, the layout of transmission system becomes and has great difficulty.Along with the increase of rocker arm of coal mining machine power, the particularly increase of rocking arm clipping force, guarantee cutting capacity and the effect of loading coal of rocking arm to make design difficulty greatly increase simultaneously in limited girdle space.

Existing low seam mining machinery in recovery process, adopts dual mode to coaling usually:

The first is for coalingging by rocking arm jib below, and double-ended shearer adopts two cylinders to inner rotary usually.Cut top cutter Rocker drum because cylinder is raised, the coal port of rocking arm jib below can guarantee to coaling substantially; But cut the bed plate Rocker drum usually due to diameter of cylinder less (particularly low seam mining machinery); rocking arm jib below and transporter ledge form crosses coal channel and will become very little; this state Rocker drum can't be coaling this moment; coal cinder in the cylinder side by second-time breakage; not only consume the excess power of rocking arm; severe patient travel fatigue will make the work plane worsening condition, can't mine, this state also can't form lump coal.

The second is that double-ended shearer adopts two cylinders inwardly to rotate usually by coalingging the rocking arm outer end.Because the common front roll of this mode of coalingging is coaling, back roll is seldom coaling.In order to improve effect of loading coal, the dealer often realizes coalingging of two cylinders by the crowded coal plate mode that increases various structures on rocking arm.The use of squeezing coal plate mode is fit to work plane and reach a certain height, and can give to squeeze coal plate upset etc. the work plane in space is provided; The thin seam working surface that mining height is less has certain limitation to the use of squeezing coal plate mode.Although squeeze the use of coal plate mode, can solve the coal loading problem of certain work plane to a certain extent, but it uses by the coal cinder extruding being released the mode of coal port, not only consumes a large amount of extra energy consumptions, and the Dust Capacity that forms is also larger, and it is also just smaller that this state coal mining forms lump coal.

As shown in Figure 6, Figure 7, Fig. 6, Fig. 7 are the existing structure rocker arm of coal mining machine cylinder schematic diagram that coal is coaling from the jib below of rocking arm while outwards turning.Because diameter of cylinder is less, when this Rocker drum is cut off cutter; the underneath clearance that forms between 14 belows, rocking arm jib bottom surface and ledge end face 64 is very little; coal cinder will be extruded and take on from this height C in a small amount; but a large amount of coal cinders is formed a large amount of dust in the cylinder side by second-time breakage; and also constantly by drum extrusion, being thrown to rear is piled into a large amount of float coal, and this kind mode can't form lump coal.

As shown in Figure 8, Figure 9, Fig. 8, Fig. 9 are existing structure Rocker drum coal schematic diagram of coalingging from the rocking arm outer end while inwardly turning.Usually adopt the crowded coal plated construction of variety of way due to this mode of coalingging, a large amount of coal cinders is also formed a large amount of dust by second-time breakage in the cylinder side, only forms a small amount of lump coal.

In view of this, for the coal-winning machine technology of China's thin seam mining, urgent need will find new way, reduces the repeatedly broken and reduction dust of coal mining process mining equipment for coal, improves the economic benefit of coal mining, solves the high lump rate mining problem of coal.

As a kind of preferred version of the present utility model, described jib also comprises the jib facade, and this jib facade is parallel with the ledge facade of the transporter that is used in conjunction with, and has gap, the gap of cutting sth. askew when the corresponding coal-winning machine in this gap is positioned at the coal cutting of transporter top.

As a kind of preferred version of the present utility model, described jib also comprises the oblique facade of jib that is positioned at jib one side, and the oblique facade of jib is parallel with the ledge shovel board face of transporter.

As a kind of preferred version of the present utility model, described jib also comprises the jib bottom surface, this jib bottom surface is parallel with the ledge bottom surface of the transporter that is used in conjunction with, and on two sides near the time, Rocker drum has the incision amount of needs in the time of meeting coal-winning machine and be positioned at transporter two ends tops and cut Triangle Coal.

As a kind of preferred version of the present utility model, described jib flat top surface is identical with the ledge apical side height of transporter.

The beneficial effects of the utility model are: the rocker arm of coal mining machine with high lump coal rate that the utility model proposes, be arranged at transporter ledge side by the jib with rocking arm, form the open coal channel of crossing above the jib of rocking arm housing, take full advantage of the drum blade angle coal is thrown the transporter of packing into; , because the open coal channel of crossing loads and do not produce obstruction coal stream, therefore solved the coal loading problem of low seam mining machinery, thereby improved lump coal rate.
