According to a simple especially embodiment of the present invention, its design is that sliding part is connected in excavating arm, and can be parallel to the front surface revolution that switch is housed of cover.This embodiment can have the form of splice bar, and it also can be contained on the excavating arm afterwards, so can be replenished simply the existing material machine that digs.
Below with reference to more detailed ground explain the present invention of embodiment shown in the drawings.
Fig. 1 represents to be furnished with the lateral view that digs the material machine according to device of the present invention,
The axial cross section of the sliding part in the embodiment that Fig. 2 represents to be used as conveyer and to be applied in Fig. 1,
Fig. 3 represents an improved embodiment,
Fig. 4 represents along the cross section of Fig. 3 IV-IV line
Fig. 5 represents a further improved embodiment of conveyer that comprises sliding part.
Fig. 1 represents the material machine 1 that digs that can move on caterpillar chassis 2.Charging plate or loading platform 4 are connected in pivotally and dig material machine frame 5 with wraparound rotating shaft 3 revolutions, and gyroaxis is parallel with the walking surface of the crawler belt of caterpillar chassis 2 basically.Dig stub bar 7 and be rotatably supported on the excavating arm 6, excavating arm is supported to do vertical direction and the gyration shown in double-head arrow 8 basically.Rotating gyroaxis was represented with 9 about excavating arm 6 was done.And the gyroaxis 10 of perpendicular is used for making excavating arm 6 to make universal turning, and excavating arm 6 mats one supporting disk device be bearing in dig the material machine frame 5 on, the shell of supporting disk device is represented with 11.There is the conveying arrangement 12 that transports the material that cuts or excavate the back of digging the material machine.
Be provided with a conveyer sliding part 13 digging between material machine frame 5 and loading platform or the charging plate 4, it comprises a sliding part 14 that is connected in loading platform or charging plate pivotally, and one is connected in pivotally and digs the pipe box of expecting machine frame 5.An essentially identical similar conveyer sliding part 13 of structure is connected in the shell 11 and the excavating arm 6 of supporting disk device pivotally, and this moment, sliding part 14 was also to be connected in excavating arm, and pipe box 15 is connected in the supporting shell of supporting disk device.
