A piece rotating bar, the right-hand member of the rotating bar are connected with the output shaft rotation for the first motor being arranged on inside interior bar；Institute's rheme
Gear in top slidably connects a connecting rod, the left end of the connecting rod and be arranged on interior bar left end dividing plate the
Two motor connections, the output shaft of second motor are connected with cursor through dividing plate by shaft coupling, the cursor it is another
One end is installed with rotary head.
It is preferred that it is provided with balancing weight on the cursor.
It is preferred that the connecting rod is provided at both ends with stop collar.
It is preferred that the rotating bar is provided at both ends with stop collar.
Compared to the prior art the utility model, the advantage is that：
A kind of excavator scraper bowl provided by the utility model, can effectively reduce toothholder on scraper bowl excavate hardness compared with
During big material, damaged caused by heavy wear；Rotated by the second motor driven cursor, and then drive rotary head to turn
Dynamic, the rotation of rotary head effectively can crush the larger material of hardness, so as to avoid the abrasion of toothholder on scraper bowl；When
Need to carry out deeper it is broken when, start the first motor and rotate, and then pass sequentially through rotating bar, lower gear, gear, connection
Bar drives interior bar to stretch out outer bar, so as to effectively increase the collapsing length of cursor, has reached the work of deeper.

Embodiment
Below in conjunction with the accompanying drawings, an embodiment of the present utility model is described in detail, it is to be understood that this
The protection domain of utility model is not limited by embodiment.
As shown in Figure 1-2, the utility model embodiment provides a kind of excavator scraper bowl, including bucket body 1, described
A mounting seat 2 is respectively arranged with two side plate 1-1 of bucket body 1, electric expansion is fixedly connected with the mounting seat 2
Bar 3, the electric expansion bar 3 include interior bar 4 and outer bar 5, and the outer bar 5 is coaxially set in the outside of interior bar 4, interior bar 4 it is interior
End is additionally provided with pinion stand 8, and the pinion stand 8 is provided with one group of pitch wheel 9, the gear 9 include gear 9-1 with
Lower gear 9-2, the underlying lower gear 9-2 slidably connect a rotating bar 7, and the right-hand member of the rotating bar 7 is with setting
The output shaft rotation connection of the first motor 10 inside interior bar 4 is put, specifically, the center of lower gear is provided with a connecting hole,
Keyway is provided with the connecting hole, keyway is correspondingly also equipped with rotating bar, rotating bar passes through the connecting hole at lower gear center simultaneously
