Abstract
The utility model relates to the manufacture field of coal mining devices for a coal mine, in particular to a coal cutter rotary drum for cutting a hard dirt band, which comprises a rotary drum body, an end plate, blades, tooth holders and cutting teeth. Spiral blades are arranged on the rotary drum body evenly, the tooth holders are arranged on the spiral blades, the cutting teeth are arranged on the tooth holders, the tooth holders are distributed on the end plate, the cutting teeth are arranged on the tooth holders through cutting tooth sleeves, and the cutting teeth and the cutting tooth sleeves are connected in rotating mode. 12-28 tooth holders are distributed on the end plate evenly, and a cutting tooth is connected with the inside of each tooth holder through the cutting tooth sleeves. Four groups of spiral blades are distributed on the rotary drum body evenly, and 6-9 cutting teeth are distributed evenly on each group of spiral blades. An arrangement structure of the cutting teeth of the tooth holders at the end plate is optimized, an arrangement angle of the tooth holders of the end plate ranges from -8 to 36 degrees, and a range of the arrangement angles of the cutting teeth is enlarged. The coal cutter rotary drum for cutting the hard dirt band has the advantages of being reasonable in structure, long in service life of the rotary drum, strong in rock breaking capacity and capable of cutting the hard dirt band.
Description
Technical field
The utility model relates to a kind of coal mining manufacturing field of equipment, the coal mining machine roller of the hard dirt band of specifically a kind of cut.
Background technology
Existing mining coal mining machine roller is because rock breaking capacity is poor.When coal-winning machine runs into the coal seam and contains hard dirt band, need beat and put the broken rock of vibrations big gun.With certain pit coal layer is example, about 1.5 meters of coal seam thickness, and wherein dirt band thickness is 0.4 meter; And dirt band hardness is big, and traditional coal-winning machine at first contacts the bigger dirt band of hardness because of the end plate of cylinder, and the pick on the end plate is the easiest to be impaired; End plate rock breaking capacity after the wearing and tearing obviously reduces, and causes the cylinder at rear portion to carry cut, thereby has influenced the whole operating efficiency of equipment; Production cycle is long, and worker's labour intensity is big, the organism of production difficulty.Selected high-power MG300/700-WD type coal-winning machine afterwards for use, realized comprehensive mechanical coal mining,, obtained certain effect, but improved cost and do not solved the broken dirt band mining problem in this coal seam preferably, and still need beat and put the vibrations big gun through field trial.Also there are problems such as effect of loading coal difference in present coal mining machine roller, and above-mentioned technical problem is restricting the raising of coal work efficient always.
Summary of the invention
The utility model provides a kind of rational in infrastructure in order to overcome above-mentioned defective, the cylinder long service life, and rock breaking capacity is strong, but the coal mining machine roller of the hard dirt band of cut.
The technical scheme that the utility model adopts is: the coal mining machine roller of the hard dirt band of a kind of cut; Comprise cylinder body end plate, blade, toothholder and pick, evenly be laid with helical blade on the cylinder body, toothholder is set on the helical blade; Pick setting on the toothholder; Distributed and arranged has toothholder on end plate, and pick is installed on the toothholder through the pick cover, and pick and pick cover are be rotationally connected
.
Even distributed and arranged has 12-28 toothholder on the described end plate, all connects a pick through the pick cover in each toothholder.Optimize end plate toothholder pick arrangement architecture, end plate toothholder pick arrangement angle is selected-8 °～36 ° for use, has enlarged pick arrangement angle scope.
Evenly be laid with four groups of helical blades on the described cylinder body.
Described pick is a pick-shaped cutter, and the work plane of its crown is provided with the molten alloy wear-resisting layer that applies.
The utility model is provided with toothholder on the end plate of cylinder, and pick is installed on the toothholder through the pick cover, makes pick and pick cover for being rotationally connected; Pick on the end plate rotates in toothholder with the rotation of end plate when work like this, does not produce the rigidity cutting with the hard dirt band of point, and abrasion resistance improves; Be specially adapted to the hard dirt band of cut; Thereby protection cylinder end plate has improved the whole operating efficiency of cylinder, prolongs the application life of cylinder; The pick of end plate is increased to 12-28 by traditional 9-18, and three groups of helical blades of tradition laying on the cylinder body are increased to four groups, can improve the rock breaking capacity and the coal capacity of equipment.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model, comprises cylinder body 1 end plate 3, blade 7, toothholder 9 and pick 8, evenly is laid with helical blade 7 on the cylinder body 1; Toothholder 9 is set on the helical blade 7, and pick setting 8 on the toothholder 9.In the present embodiment, evenly be laid with four groups of helical blades 7 on the cylinder body 1.Distributed and arranged has toothholder 9 on end plate 3, and pick 8 is installed on the toothholder 9 through pick cover 2, and pick 8 overlaps 2 for being rotationally connected with pick.The toothholder of the utility model can be set to 12-28; In the present embodiment; Even distributed and arranged has 28 toothholders 9 on the end plate 3, all connects a pick 8 through pick cover 2 in each toothholder 9, and described pick 8 is a pick-shaped cutter 8; The work plane of its crown is provided with the molten alloy wear-resisting layer that applies, and the molten alloy wear-resisting layer that applies is selected chromium nickel molybdenum or chromium nickel-manganese material for use.
The utility model is through being provided with toothholder 9 on the end plate 3 of cylinder, and pick 8 is installed on the toothholder 9 through pick cover 2, sees Fig. 2; Make pick 8 and pick overlap 2 for being rotationally connected, the pick 8 on the end plate 3 rotates in toothholder 9 with the rotation of end plate 3 when work like this, does not produce the rigidity cutting with the hard dirt band of point; Abrasion resistance improves, thereby protection cylinder end plate 3 is specially adapted to the hard dirt band of cut; Improve the whole operating efficiency of cylinder, prolonged the application life of cylinder; The utility model can also increase 12-28 with the pick 8 of end plate 3, and three groups of helical blades 7 perhaps tradition on the cylinder body 1 being laid increase to four groups, evenly lay 6-9 pick 8 on every group of helical blade 7.Can improve the rock breaking capacity and the coal capacity of equipment.
The utlity model has rational in infrastructure, the cylinder long service life, rock breaking capacity is strong, but the characteristics of the hard dirt band of cut.
