Abstract
The invention relates to a thin-coal-layer double-connection cutting-loading cutting part and relates to the field of hard thin-coal-layer coal mining machine. The cutting part comprises a cutting part shell, a cutting motor, a clutch, a gear transmission system and a cutting roller. The cutting motor, the clutch, the gear transmission system and the cutting roller are arranged on the cutting part shell. The cutting motor is connected with the gear transmission system through the clutch. The power of the cutting motor is output to the cutting roller after speed reduction is conducted through the gear transmission system. Integrated cutting-loading of a traditional single cylindrical roller is converted into two rollers which are transversely arranged and used for breaking coal and containing coal respectively. Cutting teeth of a conical roller of the thin-coal-layer double-connection cutting-loading cutting part are concentrated in distribution, the coal breaking capacity of a single cutting tooth is high under the condition of constant power, and a hard coal layer can be effectively cut; the cylindrical roller is good in the coal containing effect, the cutting depth and cutting width of the cylindrical roller are the same as those of the conical roller, the rotation directions are opposite to each other, the cutting strength of the cylindrical roller in secondary cutting can be effectively reduced through cooperation of the cylindrical roller and the conical roller, and waste-free exploitation of the thin coal layer is achieved.
Description
Technical field
The present invention relates to a kind of duplex and cut dress cutting units, especially a kind of girdle duplex being applicable to hard low seam mining machinery cuts dress winning machine cutting part.
Background technology
The coal seam of current China 19% is all girdle, but the exploitation space of girdle is little, and operating condition is severe, yields poorly, and is a difficult problem for puzzlement coal in China industry.In recent years, along with mechanization degree improves, the thick and medium-thickness seam reserves of China reduced increasingly, and even exhausted, therefore the research of thin seam mining technology must be paid attention to.It is a kind of relatively traditional coal-mining technique exploiting girdle that drum-type is mined.Cutting units is the core component of coal-winning machine, and its performance quality directly has influence on cutting capacity and the economic benefit of coal-winning machine.Girdle thickness is many at below 1.3m, and seam hardness is large, and traditional cylindrical drum pick distribution is not concentrated, and cutting capacity is weak; And due to girdle narrow space, require that coal-winning machine fuselage is lower, meanwhile limit the size of cylinder, cause coal mining output to reduce, cost is high.Therefore, need the research carried out high-efficiency mining hard girdle in a hurry, particularly a kind of novel, efficient winning machine cutting part of research.
Summary of the invention
Technical problem: the object of the invention is for Problems existing in prior art, provides that a kind of structure is simple, cutting capacity is strong, can realize carrying out hard girdle the duplex of effectively exploitation to cut dress winning machine cutting part.
Technical scheme: girdle duplex of the present invention cuts dress winning machine cutting part, comprise cutting units housing, the clutch be located on cutting units housing, cutting motor, pinion unit unify cutting drum, wherein cutting motor is connected by clutch with gear train assembly, and the power of cutting motor exports cutting drum to after gear train assembly slows down; Described cutting drum comprises the taper cutting drum being located at cutting units housing upper and the cylindricality cutting drum being located at cutting units lower housing portion, the power that cutting motor exports is become two-way through gear shunting by described gear train assembly, one tunnel exports taper cutting drum to, and another road exports cylindricality cutting drum to.
Described gear train assembly comprises lazy axle one, section axle one, section axle two, cuts axle three, section axle four, lazy axle two, lazy axle three, section five axles, planetary mechanism one and planetary mechanism two, through meshed transmission gear; Power transmission extremely cuts on the gear wheel on axle three by the idle pulley of the shaft gear on described section of axle one on lazy axle one and the idle pulley cut on axle two, and drive cuts the pinion rotation of axle three, power is reached the gear wheel cut on axle four, thus drive is rotated with a section axle four; Power is split into two-way cutting axle four: the shaft gear idle pulley of the lazy axle of transmission two, the idle pulley of lazy axle three and cut the shaft gear of five axles successively that a route cuts axle four, the shaft gear transmission planetary mechanism one cutting five axles by power transmission to taper cutting drum; Another route cut axle four pinion successively transmission cut the idle pulley of axle three, cut the shaft gear of axle two, the shaft gear transmission planetary mechanism two cutting axle two by power transmission to cylindricality cutting drum.
The direction of rotation of described taper cutting drum and cylindricality cutting drum is contrary.
Described taper cutting drum is identical with the cut degree of depth with the diameter of cylinder of cylindricality cutting drum.
Beneficial effect: the present invention is applicable to the exploitation to hard girdle, traditional cylindrical drum pick distribution is not concentrated, and cutting capacity is weak; And due to girdle narrow space, require that coal-winning machine fuselage is lower, and limit the size of cylinder, the conical drum of this cutting units, when winning machine cutting part power is constant, conical drum diameter diminishes, and clipping force increases naturally; Meanwhile, for cylindrical drum provides the more scope of freedom after conical drum cut, cylindrical drum cut is convenient to.These two aspects are all favourable to the cutting capacity improving cutting units.Traditional single cylindrical drum is cut dress and is integrally changed two cylinder lateral arrangement into by the present invention, is responsible for broken coal respectively and coalings, making total appearance coal rate of cutting units increase nearly one times, the efficiency substantially increasing cutting units coal cutting and coaling.Wherein conical drum pick distribution is comparatively concentrated, and under invariable power condition, to break coal ability strong for single pick, can effective cut hard coal seam; Cylindrical drum effect of loading coal is better, identical with cut width with the conical drum cut degree of depth, turns to contrary, effectively prevents the radial impelling of coal cinder, both can play the effect of spillplate, also effectively other coals under conical drum cut can be filled to conveyer.And due to the leading cut of conical drum, the stress between coal seam is discharged, effectively can reduce the cutting strength of cylindrical drum when secondary cut, achieve exploiting without waste girdle.Its compact conformation, rationally, simple, cutting capacity is strong, has practicality widely.
