Abstract
The utility model discloses a tapered rock-breaking spiral drum of a coal mining machine, which belongs to the technical field of cutting machinery. The tapered rock-breaking spiral drum comprises a drum body and a cutting system, wherein the cutting system consists of a cutting saw and a saw base; the cutting saw is arranged on the saw base; the front part of the drum body is of a tapered structure; the saw base is directly welded on the surface of the drum body; and the cutting system is arrayed and distributed on the surface of the drum body according to 6 Archimedes spirals. The tapered rock-breaking spiral drum has the beneficial effects that: the cutting radius is reduced; the cutting resistance is reduced; and because the spiral drum is tapered and can excavate coal under the condition of not blasting, the production efficiency is improved.
Description
Technical field
The utility model relates to the broken rock shell rotating drum of a kind of coal-winning machine taper, belongs to the cutting machine technical field.
Background technology
Coal-winning machine adopts helix drum to carry out coal mining activity usually, it is by cylindrical shell, end plate, blade, toothholder and pick are formed, end plate one side is near rib, coal-winning machine drives the cylinder rotation, by the pick on end plate and the blade coal cut from the coal seam is got off, because this cylindrical screw diameter of cylinder that has end plate and a blade is big, the resistance of cut is just big, if coal seam dirt band stone, cutting resistance acutely increases, and will cause the cylinder lag switch when surpassing the motor rated load, and this helix drum just can't coal cutting, have only by on the coal seam, putting the vibrations big gun and shake loose coal seam and could continue coal cutting, still so just caused production efficiency to reduce greatly.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of coal-winning machine taper to break the rock shell rotating drum, reduces cutting resistance, and helix drum is taper, has improved production efficiency.
To achieve these goals, the technical solution adopted in the utility model is: the rock shell rotating drum is broken in a kind of coal-winning machine taper, comprise cylindrical shell and cut system, the cut system is made up of pick and toothholder, pick is installed on the toothholder, the cylindrical shell front portion is a pyramidal structure, and toothholder directly is welded on drum surface, and 6 spiral of Archimedes arranged are pressed at drum surface by the cut system.
The beneficial effects of the utility model are: reduce the cut radius, reduce cutting resistance, helix drum is taper, can mine under the situation of not putting the vibrations big gun, has improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, cylindrical shell, 2, the cut system, 21, pick, 22, toothholder.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the rock shell rotating drum is broken in a kind of coal-winning machine taper, comprise cylindrical shell 1 and cut system 2, cut system 2 is made up of pick 21 and toothholder 22, pick 21 is installed on the toothholder 22, cylindrical shell 1 front portion is a pyramidal structure, and toothholder 22 directly is welded on cylindrical shell 1 surface, and 6 spiral of Archimedes arranged are pressed on cylindrical shell 1 surface by cut system 2.
Claims (2)
