Preferably; Be provided with preceding supporting, middle supporting and back supporting in the said casing; Said preceding supporting, middle supporting and back supporting are connected with biside plate 4 through welding respectively, and said preceding supporting forms said scraper bowl Connection Block 6, the swing arm Connection Block 8 of said back supporting formation excavator boom; Said preceding supporting rear is located in supporting in said, and reclines with said preceding supporting.
Preferably, said traction element is through being welded in said side plate 4 inboards, and said traction element is connected with said side plate 4 with the pasting board of said side plate 4 connecting portions.
Preferably, said bent plate 3 is provided with bucket arm cylinder seat 9.
Preferably, said stiffener 7 bottom surfaces are provided with many reinforcing ribs that parallel longitudinal distributes.
Preferably, every block of said side plate 4 is mainly formed by front side board 41 and back side panel 42 amalgamations, and the mosaic of said front side board 41 and back side panel 42 is arranged in said supporting tail end.
Preferably, said traction element is the drag-line of pull bar or prior pretension.
A kind of excavator wherein, comprises above-mentioned excavator boom.
The beneficial effect of technique scheme is:
Increase the dipper flexibility through increase traction element in box house, divide equally the dipper stress level, reduce stress concentration point, improve the dipper life-span.
