Abstract
The utility model belongs to a helix drum, in particular to a helix drum of an internal and external helical line lead-changeable coal cutter, in order to solve the problem that the coaling effect is not good when the helix drum of the coal cutter works. The helix drum of the internal and external helical line lead-changeable coal cutter comprises a drum body (1) and a helical blade (2), wherein the helical blade (2) is fixedly connected to the external surface of the drum body (1); the common perpendicular of the inner helical line (2-1) and the outer helical line (2-2) on the helical blade (2) and the axis of the drum body (1) form an acute angle; the inner helical lead (L1) of the helical blade (2) is smaller than the outer helical lead (L2) of the helical blade (2). The helix drum is mainly used for the coal cutter.
Description
Technical field
The utility model relates to a kind of helix drum, is specifically related to a kind of internal and external screw line and becomes helical pitch Shearer Helical Drum.
Background technology
The helix drum of low seam mining machinery application at present, generally adopts positive cylindrical screw drum blade, and internal and external screw line helical pitch is identical, the structure design that blade is vertical with cylindrical shell, and the effect of loading coal of such Shearer Helical Drum cylinder in the time of work is unsatisfactory.
Utility model content
The utility model is to solve the effect of loading coal bad problem of existing Shearer Helical Drum in the time of work, and then proposes a kind of internal and external screw line change helical pitch Shearer Helical Drum.
The utility model takes technical scheme to be for addressing the above problem: the utility model comprises cylindrical shell and helical blade, helical blade is fixed in the external surface of cylindrical shell, the angle that on helical blade, the common vertical line of inner vortex and outer vortex and the axis of cylindrical shell form is acute angle, and the inside spin helical pitch of helical blade is less than the external spiral helical pitch of helical blade.
The beneficial effects of the utility model are: the utility model is simple in structure, and forming cylinder blade and cylindrical shell acutangulate, and have reduced the effect of coal cinder due to centrifugal force, make coal along blade to the cylinder of dishing out, and loading effect has been improved more than 10%.
Accompanying drawing explanation
Fig. 1 is the integrally-built schematic diagram of the utility model; Fig. 2 is the top view of Fig. 1.
The specific embodiment
The specific embodiment one: as shown in Figure 1-2, described in present embodiment, a kind of internal and external screw line change helical pitch Shearer Helical Drum comprises cylindrical shell 1 and helical blade 2, helical blade 2 is fixed in the external surface of cylindrical shell 1, the angle that on helical blade 2, the common vertical line of inner vortex 2-1 and outer vortex 2-2 and the axis of cylindrical shell 1 form is acute angle, and the inside spin helical pitch L1 of helical blade 2 is less than the external spiral helical pitch L2 of helical blade 2.
It is affixed that design like this acutangulates helical blade 2 and cylindrical shell 1, and external spiral helical pitch L2 is greater than inside spin helical pitch L1 simultaneously, can effectively improve effect of loading coal.
The specific embodiment two: as shown in Figure 1-2, the inside spin lift angle of helical blade 2 is identical with the external spiral lift angle of helical blade 2 described in present embodiment.Other composition and annexation are identical with the specific embodiment one.
So design, can avoid because inside spin lift angle is excessive, causes the coal cylinder of dishing out, and has effectively improved loading effect.
The specific embodiment three: as shown in Figure 1-2, helical blade 2 is welding with the connected mode of cylindrical shell 1 described in present embodiment.Other composition and annexation are identical with the specific embodiment one or two.
The specific embodiment four: as shown in Figure 1-2, the external spiral at helical blade 2 two ends and the poor H of helical pitch of inside spin are 30mm～70mm described in present embodiment.Other composition and annexation are identical with the specific embodiment three.
Claims (4)
