Detailed description of the invention:
As it is shown in figure 1, the stretching withdrawer of a kind of negative pressure air duct, it is included on drive wall and is hung with steel wire rope 1.If
Put a negative pressure air duct 2, the outer wall of negative pressure air duct 2 is provided with the link 1a of a group and steel wire rope 1 corresponding matching, in order to will be negative
Pressure air duct 2 is suspended on steel wire rope 1, and negative pressure air duct 2 can be made to seesaw along steel wire rope 1.
A piece vertical montant 6 is set, is provided with cord hole 3a of and steel wire rope 1 corresponding matching on the top of montant 6,
The bottom of montant 6 is provided with a screw rod 6a being coaxial therewith, then arranges a thickening hollow pipe 3, in the upper end thickening hollow pipe 3
It is provided with gear-box 6b.
The lower end of described screw rod 6a is stretched in the tube wall thickening hollow pipe 3 after gear-box 6b again.At described tooth
It is additionally provided with lifting rocking bar 6c on roller box 6b, realizes the up and down motion of screw rod 6a by rotating lifting rocking bar 6c, and then realize perpendicular
The lifting of bar 6, and the axis of described montant 6 with thicken hollow pipe 3 axis conllinear.
As shown in Figure 1, 2, one is arranged by the air duct storage metal frame 4 of bonding jumper braiding, described air duct storage
Metal frame 4 diameter is less than the diameter of negative pressure air duct 2, and profile is bullet-shaped, and its top arc end is outside, in order to received by air duct
Metal frame 4 inserts in negative pressure air duct 2, and the bottom of described air duct storage metal frame 4 is connected with montant 6, and described air duct is received
Receive axis and the montant 6 of metal frame 4 and the axis perpendicular of thickening hollow pipe 3.
The shaft thickening hollow pipe 3 bottom is provided with the installation screw 3a of one group of genesis analysis, under installation screw 3a
It is additionally provided with a fixed pulley 3b on the shaft thickening hollow pipe 3 of side.On the outer wall thickening hollow pipe 3 of fixed pulley 3b side
It is also associated with a horizon bar 3d, horizon bar 3d is additionally provided with and the capstan winch 5 of steel wire rope 1 corresponding matching, in described level
Bar 3d is provided with the installation screw 3a of one group of horizontal distribution.Steel wire rope 1 is being wound around downwards through cord hole 3a after fixed pulley 3b
On capstan winch 5.
The air duct wall of described negative pressure air duct 2 air draught end is evenly equipped with one group of through hole (not regarding in figure), at each through hole
In be all equipped with iron wire, in order to according to job demand, negative pressure air duct 2 is connected to the suitable position in air duct storage metal frame 4 framework
Put.
Work process:
As shown in Figure 3,4, according to working condition actual in drive, by the installation thickeied on hollow pipe and horizon bar
Screw arranges fixing bolt, will thicken in the frame that hollow pipe and horizon bar are connected to fully-mechanized digging machine or fully-mechanized digging machine two is transported, then
By the handle on rocking gear case, air duct is received metal frame and is adjusted to suitable height.
Air duct on support bar is received metal frame and inserts negative pressure air duct from the air draught end of negative pressure air duct, and by being positioned at suction
Iron wire in through hole on wind end air duct wall, is connected to negative pressure air duct in the framework of air duct storage metal frame.And unnecessary negative pressure
Air duct can produce fold and be deposited in the junction of negative pressure air duct and air duct storage metal frame.
Along with moving before and after fully-mechanized digging machine, negative pressure air duct can be drawn forward and trail and suspend in midair on a steel cord or receive backward
Returning on air duct storage metal frame outer wall, simultaneously wound steel wire rope on capstan winch also can release or regain.
When thus can effectively avoid fully-mechanized digging machine retrogressing in prior art, negative pressure air duct surplus is more cannot be effective
Receiving, produce air duct bending section, under suction air duct generation skew back, cause air duct ventilation section to strongly reduce, suction air volume drops
Low situation occurs.
Additionally, according to the practical situation in drive, it is also possible to select negative pressure air duct connects air duct storage metal frame framework
Diverse location on.This is because, when fully-mechanized digging machine driving route is more straight, just negative pressure air duct is connected to air duct storage gold
Belong to the rear portion of circle body near the position of support bar, in order to this utility model drives negative pressure air duct, can straight line before and after smoothness
Motion；And when fully-mechanized digging machine driving route compares bending, then before negative pressure air duct being connected in air duct storage metal frame framework
Portion, in order to this utility model drives negative pressure air duct while tandem moves, and negative pressure air duct can be driven again to carry out necessarily
Curvilinear motion before and after angle.
