Close continuous chain 55.
As described in Fig. 3 and 4 best seen from, scraper plate 60 end 90 each include top shoulder 93 and from top shoulder 93 along direction
The bottom shoulder 95 that the direction of the siding track 48 of intermediate channel 45 extends.Top shoulder 93 each limit first or upper guiding surface 97, and bottom
Shoulder 95 each limit second or lower guiding surface 98.When scraper plate 60 is positioned in the trench portions 70 of top, upper guiding surface 97
Each corresponding one in the outer fissure groove face 77A, and lower guiding surface 98 each in septal fossula groove face 79A corresponding one
It is individual.When scraper plate 60 is positioned in cunette slot part 73, upper guiding surface 97 each in the outer fissure groove face 77B corresponding one
It is individual, and lower guiding surface 98 each corresponding one in the septal fossula groove face 79B.
Do not consider scraper plate 60 whether top trench portions 70 or cunette slot part 73 in, scraper plate 60, top trench portions 70, bottom
The geometry of trench portions 73 causes each end for scraper plate 60, the outer fissure groove face 77A corresponding to its of upper guiding surface 97
Or the distance between the distance between 77B septal fossula groove face 79A or 79B its corresponding with lower guiding surface 98 is roughly the same.By
This, when 60 transverse shifting during running of scraper plate, if upper guiding surface 97 is contacted with outer fissure groove face 77A or 77B, under draw
Surface 97 is led substantially simultaneously to be contacted with septal fossula groove face 79A or 79B.Because in the presence of two contact surfaces, reducing scraper plate
Abrasion on 60 and in intermediate channel 45.When scraper plate 60 push up 70 center of trench portions when, on each end of scraper plate 60 on draw
Lead the distance between the outer fissure groove face 77A corresponding to its of surface 97 roughly the same, and the lower lead schedule on each end of scraper plate 60
The distance between the septal fossula groove face 79A corresponding to its of face 98 is also roughly the same, and and upper guiding surface 97 and outer fissure groove face 77A between
Distance it is roughly the same.When scraper plate 60 is at cunette 73 center of slot part, situation is identical.
As Figure 4-Figure 6, in certain embodiments, the top shoulder 93 of scraper plate 60 also includes that low friction guides system, and this is low
Friction guidance system operationally guides scraper plate along outer fissure the groove face 77A or 77B of intermediate channel.For example, guiding system may include peace
Roller 99 in the first vertical portion 97 of top shoulder 93, outer fissure the groove face 77A or 77B of roller contact intermediate channel 45.
The material removed by cutter 15 drops on mobile face conveyer 20.Each intermediate channel 45 of face conveyer 20
Therefore supporting, capture and the line guiding scraper plate 60 along the side 46 and 47 parallel to intermediate channel 45 simultaneously guide continuous chain 55.It is specific next
Say, the guiding of the middle scraper 60 of conveyer 20 and chain 55 and capture ability are by the top trench portions 70 of intermediate channel 45 and cunette that improve
The construction of the shoulder 93 and 95 of the construction (also referred to as Sigma's profile of intermediate channel) and scraper plate 60 of slot part 73 is provided.As schemed
Shown in 2-4, existing construction allows the first vertical portion 97 for pushing up shoulder 93 to be aligned with outer fissure the groove face 77A and 77B of intermediate channel 45,
And the second vertical portion of bottom shoulder 95 is aligned with septal fossula the groove face 79A and 79B of intermediate channel 45.Therefore, the outer fissure of intermediate channel 45
Groove face 77 and septal fossula groove face 79 are configured to be maintained at scraper plate 60 in the center relative to intermediate channel.
When scraper plate 60 is moved along intermediate channel 45, the traction and supporting of their scraper plates 45 and the component of continuous chain 55 by improving
The construction guiding.As shown in figure 3, when being moved in plate part 65, scraper plate 60 is shelved on the upper part 83 of plate 50 simultaneously
By using the alignment between the first vertical portion 97 and outer fissure groove face 77A, and the second vertical portion 98 and intermediate channel 45
Alignment between septal fossula groove face 79A is moved.Additionally, when scraper plate 60 is moved in the channel part 67 of intermediate channel 45, utilizing
The vertical portion 97 and 98 of scraper plate and the similar alignment between grooved surface 77B and 79B.
Therefore, in order to the fixed but not movement of limiting scraper 60, the first and second vertical portions 97 and 98 are insecure
Be connected to outer fissure groove face 77A/77B and septal fossula groove face 79A/79B.When scraper plate 60 is guided along intermediate channel 45, intermediate channel 45
Increased number of vertical plane 77 and 79 reduces the power for being applied to each vertical plane 77 and 79.Therefore, reduce intermediate channel 45 with
And the wear extent on scraper plate shoulder 93 and 95.Additionally, for intermediate channel 45, the construction make it possible to vertically with level side
To the less Sigma's profile of use.
Fig. 4-6 shows the embodiment of material extraction system 10, and the top shoulder 93 of its middle scraper 60 includes roller 99, roller
99 stretch out from the edge of top shoulder 93 towards the siding track 48 of intermediate channel 45.Specifically, roller 99 is arranged on top shoulder 93
The first vertical portion 97 on and contact outer fissure the groove face 77A and 77B of intermediate channel 45.When scraper plate 60 is along the top groove of intermediate channel 45
When part 70 or cunette slot part 73 are moved, roller 99 rotates along outer fissure groove face 77A or 77B.
In certain embodiments, the roller 99 includes the opening of the first vertical portion 97 for being mechanically incorporated into scraper plate 60
Independent component in 102 (referring to Fig. 5).In these embodiments, roller 99 can be removed by the opening 102 of scraper plate 60 and/or
Change.In alternative embodiments (Fig. 6), scraper plate 60 includes being connected to the roller of scraper plate 60 by fastener 107 (such as screw)
Component 105.Roller assembly 105 is positioned in 110 openings 109 for limiting of top point by top shoulder 93.In these embodiments,
Roller 99 is removed and/or changed by removing whole roller assembly 105.Top shoulder for roller 99 to be connected to scraper plate 60
93 other constructions or mechanism are also possible.
