Abstract
The utility model relates to a coal cutter drum, particularly relates to a non-screw type cutting drum, and solves the problems that the cutting drum of the existing coal cutter has the blade characteristics of a spiral structure, resulting in serious coal impact on the machine body and the like. The structure of the non-screw type cutting drum comprises a drum barrel, blades, a tooth holder and cutting teeth, wherein the blades are arranged at the periphery of the drum barrel, and are in the shape of a closed ring; the tooth holder and the cutting teeth are evenly distributed at the outer edges of the blades; a reinforcing rib is axially arranged between the blades; and the cutting teeth on the adjacent blades are arranged in a staggered manner. The non-screw type cutting drum can be widely applied to low seam mining machinery and the coal cutters with various models in China; green economical mining of an energy source is achieved under the same condition; the overall service life cycle of the equipment is prolonged; and the reliability and the stability of the equipment are improved.
Description
Technical field
The utility model relates to a kind of coal mining machine roller, is specially a kind of non-helical formula cutting drum.
Background technology
It is the key equipment of fully-mechanized mining working that coal-winning machine is done, and cylinder is the most direct executive component of realizing coal-winning machine coal cutting, the function of coalingging.All adopt helix drum on the existing domestic various low seam mining machineries, the structure main feature of existing coal-winning machine cutting drum is that roller tube is arranged, pick, toothholder, formations such as nozzle, roller tube adopts welded construction, adopt three or four-start spiral blade, be provided with the internal spraying water channel in the blade, and high pressure nozzle, pick, toothholder is installed on the helical blade.Effect of loading coal is all undesirable, cuts off coal basically and all realizes coalingging by flowing naturally and pushing transporter.
At thin seam working surface, especially in special thin seam working surface, the coal loading problem of conventional helical cylinder is the key issue of puzzlement girdle and special girdle work exploitation high-yield and high-efficiency always, simultaneously, because the space of coalingging of helix drum is minimum or do not have, the coal that causes helical blade to be derived directly impacts on rocking arm housing and the fuselage, makes the housing serious wear, and its reaction force also causes transmission system and cylinder fault easily.Some improvement projects change the cylinder direction of rotation, perhaps increase the cylinder spillplate, effect is very limited in the actual use in down-hole, the method that increases spillplate also can be brought a lot of negative issues, such as: cause tractive load to increase; shortcomings such as rocking arm housing and cylinder wearing and tearing aggravate, and frame head and tail commutation workload is big.
Summary of the invention
Problems such as the utility model has the blade characteristics of helical structure for the cutting drum that solves existing coal-winning machine, and the coal that brings impact fuselage is serious provide a kind of non-helical formula cutting drum.
The technical solution of the utility model is, a kind of non-helical formula cutting drum, structure comprises roller tube, blade, toothholder, pick, described blade is positioned at roller tube week side, is the ring-type of sealing, and toothholder and pick are distributed in the blade outer rim, be axially arranged with reinforcing rib between blade, the pick on the adjacent blades is staggered.
Characteristics of the present utility model are that the toothholder of cylinder is welded on the circular blade, and circle changes the shape blade and is being welded on the cylindrical shell of cylinder, in a circumferential direction, evenly arranges toothholder; Along a plurality of welding units that distribute on the axis direction, the toothholder of two adjacent groups welding unit staggers mutually, the blade pass of adjacent welding unit is crossed drum shaft to the alternately welding of high-strength abrasion-proof gusset, when guaranteeing blade and toothholder intensity, realizes getting rid of the coal function after the cylinder coal cutting.
Non-helical formula cutting drum described in the utility model is mainly used in low seam mining machinery and special low seam mining machinery, and on the girdle cutting coal machine, adopt non-helical formula blade welded construction, first, blade is a planar rings, do not produce axial thrust, the axial load that can be greatly produces when the cut rib than doffer, the application life of improving coal-winning machine planetary mechanism bearing.The second, by higher cut rotating speed, the coal that cut can be got off throws away backward, has reduced the chance of coal and rocker arm of coal mining machine and fuselage friction, has reduced the wearing and tearing of rocking arm and fuselage external surface greatly.The 3rd, convenient for maintaining reduces manufacturing cost.
Therefore, the utility model can extensively apply on the low seam mining machinery, cutting coal machine of the multiple model of China, under equal conditions, realizes the green saving exploitation of the energy, prolongs the bulk life time cycle of equipment, the reliability and stability of lifting means.
