Abstract
The invention relates to a roller for a mixed row cutting tooth coal winning machine. The roller comprises a roller hub, an end disk, pickaxe-shaped cutting teeth and a square connecting sleeve, wherein the roller hub is trapezoidal; the roller hub is provided with a diameter-variable helical blade; the front part of the diameter-variable helical blade is provided with 1 to 2 rows of pickaxe-shaped cutting teeth arranged in a checkerboard way, while the rear part is provided with a plurality of disk cutter devices arranged in the checkerboard way; and the disk cutter devices comprise an upper connecting block, a lower connecting block and disk cutter cutting teeth; the upper connecting block and the lower connecting block are welded on the diameter-variable helical blade; and the disk cutter cutting teeth, the upper connecting block and the lower connecting block are integrated into a whole through bolts. According to the characteristics of compression resistance and low tensile resistance of coal beds, different axial coal dropping amounts along the roller, the gradual diameter change of the blade and the trapezoidal appearance, the coaling effect of the roller is improved by about 15 percent compared with that of the conventional cylindrical roller, and the lump coal cutting rate is improved by 7 percent; and the roller is suitable for mining low coal beds with the coal bed thickness of below 1.3m and the dip angle of between 0 and 25 degrees. The roller has the advantages of simple and compact structure, convenient operation, good cutting effect, good coaling effect and high rock breaking ability.
Description
Technical field
The present invention relates to a kind of pick mixing type coal mining machine roller, be particularly useful for that coal seam thickness 1.3m is following, the inclination angle is the exploitation of 0～25 ° thin, ultra-thin coal seam.
Background technology
Along with the variation of coal in China exploitation form, great changes have also been taken place in the requirement of coal-winning machine operating mechanism.The coal in China exploitation is shifted to difficult working seam such as girdle, dirt band coal seam by thick, medium-thickness seam gradually, simultaneously reliability, coal cutting efficient, rock breaking capacity and the structural configuration thereof of coal mining machine roller is had higher requirement.Coal mining machine roller is born cut and functions such as shipment coal petrography and spraying firing dust, and the power of its consumption accounts for the 80-90% of whole coal-winning machine installed power, thereby its structure, pick connection and reasonable arrangement are whether, directly influence productivity ratio, energy consumption and the application life of coal-winning machine, therefore need carry out its cutting mechanism---the research of cylinder, explore new cutting mechanism form.Simultaneously, as one of technical foundation that develops mining mechanization, the research of coal-winning machine cutting mechanism is subjected to the great attention of various countries.The coal mining machine roller that present domestic girdle uses, the tube hub is a column type, and blade is made up of two parts, and is little near end plate lateral lobe sheet lift angle, and big near adopting sky side lift angle, blade diameter is identical, and the pick of installing on the cylinder is pick-shaped cutter, and end plate tilts about 15 °.The effect of loading coal of this kind cylinder is relatively poor, rock breaking capacity is not enough, is not suitable for especially using in dirt band and hard inclusion enclave coal seam.Therefore, for effectively solving the problem that has the existence of low seam mining machinery cylinder now and utilizing the not characteristic of tension of coal petrography resistance to compression, developed a kind of brute force, efficient cut, effect of loading coal mixing pick cylinder preferably.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the prior art, a kind of rational in infrastructure, cut efficient height, effect of loading coal is good, rock breaking capacity is strong mixing pick coal mining machine roller are provided.
Technical scheme: mixing pick coal mining machine roller of the present invention, comprise a hub, be welded on the end plate on the hub, end plate is provided with and is the pick-shaped cutter that checkerboard type is arranged, the square adapter sleeve of welding in the tube hub, described tube hub is trapezoidal, the tube hub is provided with the diameter variable spiral blade, and the front portion of diameter variable spiral blade is provided with 1～2 row and is the pick-shaped cutter that checkerboard type is arranged, its rear portion is provided with and is many rows dise knife device that checkerboard type is arranged; Described dise knife device is drawn together the last coupling block that is welded on the diameter variable spiral blade and lower link piece, being fixedly connected through bolt and last coupling block and lower link piece is the dise knife pick of one.
The lead angle of described diameter variable spiral blade from afterbody to the end plate position fades to 21 ° by 16 °; The end face of described end plate is L-shaped.
Beneficial effect: the present invention adopts trapezoidal tube hub, by mixing pick cylinder, is applicable to that coal seam thickness 1.3m is following, the thin seam mining at 0～25 ° at inclination angle.Its effect of loading coal has improved nearly 15% than existing column type cylinder, the cut lump coal rate has improved 7%, and it is nearly 20% that the defeated coal efficient when exploitation tilts the coal seam has improved, and broken coal ability also improves a lot.It is simple and compact for structure, easy to operate, cut efficient height, effect of loading coal is good, rock breaking capacity is strong, has practicality widely.
