Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
The phenomenon that leaking slag for slag-screening board nose wear after TBM cutterhead long distance driving, consideration are not influencing cutterhead body
Under the premise of structural strength, by slag-screening board Front-end Design at the structure of detachable changeable type.
As illustrated in fig. 1 and 2, a kind of detachable TBM cutterhead slag slippage device, including cutterhead, cutterhead are equipped with slag inlet 1,
The cutterhead is equipped with slag slippage device 4, and slag slippage device 4 includes slag-screening board 5 and wear-resistant block 6, and slag-screening board 5 is located at slag inlet 1
Bottom, end and the wear-resistant block 6 of slag-screening board 5 are detachably connected, the excircle board of the slag gathering hopper 2 in the middle part of 6 end of wear-resistant block and cutterhead
Between be equipped with gap.
The dregs that cutterhead excavates enters cutterhead back by slag inlet, is slipped and is dropped down onto slag gathering hopper by slag slippage device, then from
Dregs transportation device is fallen into slag gathering hopper, and dregs is delivered to equipment rear.
It is connect as shown in figure 3, the wear-resistant block 6 is connected through a screw thread part with the end of slag-screening board 5.It is realized by screw thread
Wear-resistant block and slag-screening board are detachably connected.
As shown in figure 3, the threaded connector is bolt 7, bolt 7 is inner bolt, and bolt 7 is located at slag-screening board 5, wear-resisting
The inside of block 6.Bolt is located inside, bolt influence is avoided to slip slag.
As in Figure 3-5, the end cross-sectional of the slag-screening board 5 is L shape, and 6 section of wear-resistant block is L shape, L-shaped wear-resistant block
6 cooperate with L-shaped 5 end of slag-screening board.L shape realizes that the smooth transition of slag-screening board and wear-resistant block connects.
As shown in Figure 1, the slag-screening board 5 includes positioned at the straight section of 1 side of slag inlet and positioned at the curved of 2 side of slag gathering hopper
Section, curved segment are straight line curved segment or curve curved segment, and curved segment bends towards the side of slag inlet 1.Slag-screening board, which is folded upward at, can be improved slag
Delay of the soil on slag-screening board, avoids dregs from falling to outside slag gathering hopper in advance.
As shown in Figure 1, the slag gathering hopper 2 includes excircle board sum aggregate slag plate, excircle board is equipped with opening, and opening is equipped with
Collect slag plate.
The gap of very little is set between excircle board and wear-resistant block end, so that cutterhead is able to drive slag-screening board rotation, is not sent out
Raw interference, while excircle board can be avoided dregs and fall from slag-screening board, until slag-screening board is rotated to opening, dregs is from opening
It falls, collection slag plate assembles dregs, avoids trickling down.
As shown in Figure 1, the segmental arc of the excircle board into plate side is longer than the segmental arc of ejecting plate side.
It is the side that slag-screening board moves closer to excircle board into plate side, ejecting plate side is that slag-screening board is gradually distance from the one of excircle board
Side will lengthen into the excircle board segmental arc of plate side, cooperate in advance with slag-screening board, block to dregs.
As shown in Figure 1, the lower part of the slag gathering hopper 2 is equipped with dregs transportation device.
As shown in Figure 1, the dregs transportation device is belt feeder 3.
The slag gathering hopper 2 is fixed on driving box.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
