Technical field
The utility model relates to a kind of winning equipment, is specifically related to a kind of helical turbine cylinder that is used for coal-winning machine.
Background technology
The domestic and international helix drum that adopts all is to realize coalingging through the helical blade that is welded on the cylindrical shell basically at present.The coal that cylinder cuts down mainly is the motion that both direction is arranged, i.e. axially-movable and tangential motion, and axially-movable can be delivered to coal in the transporter, is favourable motion; And tangential motion tangentially is thrown out of coal, falls opposite side from a rollover, falls on the machine road, belongs to unfavorable motion.Add the centrifugal force that coal mining machine roller rotation coal supply brings, be thrown out of the tangent line of a considerable amount of coals, be trapped on the machine road from cylinder.
The utility model content
The utility model provides a kind of helical turbine cylinder that is used for coal-winning machine, can control the direction of coal stream in certain limit, makes coal reach desirable motion state, improves and loads effect.
In order to achieve the above object, the utility model is realized through following technical scheme:
A kind of helical turbine cylinder that is used for coal-winning machine, the end plate that comprises cylindrical shell and link to each other with cylindrical shell, its characteristic point is also to comprise:
Some fans load blade, and described some fans load blade and are evenly distributed on the cylindrical shell circumference, and form helicla flute between the two adjacent loading blades;
Some fan cut sheets, described some fan cut sheets are installed in end plate respectively and load on the blade;
Some first pick parts, described some first pick parts are staggered to be installed on the cut sheet; And
Some second pick parts, described some second pick parts are installed on the end plate.
The radian of said cut sheet and said loading blade radian are suitable.
The described first pick parts comprise first toothholder, first pick and the first tooth cover; Described first toothholder is welded on the cut sheet; Described first pick is plugged on first toothholder through the first tooth cover.
The described second pick parts comprise second toothholder, second pick and the second tooth cover; Described second toothholder is welded on the end plate; Described second pick is plugged on second toothholder through the second tooth cover.
This cylinder also comprises U type water-supply-pipe, and described U type water-supply-pipe is welded on the cylindrical shell.
A kind of helical turbine cylinder that is used for coal-winning machine of the utility model compared with prior art has the following advantages:
The utlity model has semiclosed turbine transfer function; Can be transferred to coal in the drag conveyor through cut sheet and the formed semiclosed turbine mechanism of loading blade; Reduce tangentially being thrown out of the quantity of coal effectively, thereby reach desirable loading effect.

The specific embodiment
Below in conjunction with accompanying drawing,, the utility model is done further elaboration through specifying a preferable specific embodiment.
As shown in Figure 1, a kind of helical turbine cylinder that is used for coal-winning machine comprises: cylindrical shell 1; End plate 7, said end plate 7 links to each other with cylindrical shell 1, is used to provide the needed water of spraying; Some fans load blade 2, and described some fans load blade 2 and are evenly distributed on cylindrical shell 1 circumference, and form helicla flute (referring to Fig. 4) between the two adjacent loading blades 2, and this helicla flute is main coal circulation road; Some fan cut sheets 3, described some fan cut sheets 3 are installed in end plate 7 respectively and load on the blade 2 (referring to Fig. 2); Some first pick parts, described some first pick parts are staggered to be installed on the cut sheet 3; And some second pick parts, described some second pick parts are installed on the end plate 7; U type water-supply-pipe 6, described U type water-supply-pipe 6 is welded on (referring to Fig. 4) on the cylindrical shell 1.
As shown in Figure 3, described cylindrical shell 1 comprises a hub 11, terminal pad 12 and end plate 13.
The radian of said cut sheet 3 and said loading blade 2 radians are suitable, could guarantee enough weld strengths like this, and the quantity of cut sheet 3 generally is the twice of loading blade 2 quantity.
As shown in Figure 1, the described first pick parts comprise first toothholder 41, first pick 42 and first tooth cover 43; Described first toothholder 41 is welded on the cut sheet 3; Described first pick 42 is plugged on first toothholder 41 through first tooth cover 43.The described second pick parts comprise second toothholder 51, second pick 52 and second tooth cover 53; Described second toothholder 51 is welded on the end plate 7; Described second pick 52 is plugged on second toothholder 51 through second tooth cover 53.
When the utility model used, groundwork was coal cutting and loading, and coal cutting work mainly is to realize rotating in the feeding process of cylinder 1 in cut sheet on the cylinder 13 and second pick 52 on the end plate 7 by being assembled in assembly welding.If the shoveller decides and loads blade 2, cut sheet 3 and tube hub 11 and formed that semi-enclosed helicla flute with turbine transfer function realizes.
In sum, a kind of helical turbine cylinder that is used for coal-winning machine of the utility model can be controlled the direction that coal flows in certain limit, makes coal reach desirable motion state, improves and loads effect.
Although the content of the utility model has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to the restriction to the utility model.After those skilled in the art have read foregoing, for the multiple modification of the utility model with to substitute all will be conspicuous.Therefore, the protection domain of the utility model should be limited appended claim.
