To set 8, oil inlet passage 9, upper packing chamber 10, upper seal washer 11, lower packing chamber 12, lower seal washer 13.
Specific implementation mode：
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, the present invention provides a kind of excavator bucket oil cylinder, the bucket cylinder includes scraper bowl cylinder cylinder barrel
1, guide sleeve 2, piston rod 3, the guide sleeve 2 are mounted on the end of scraper bowl cylinder cylinder barrel 1, the scraper bowl cylinder by installing screw rod 4
O-ring 5 is additionally provided on cylinder barrel 1, for the sealing between scraper bowl cylinder cylinder barrel 1 and guide sleeve 2, the guide sleeve 2 and piston rod 3
Connection most on put and be provided with dustband 6, the lower section of the dustband 6 is provided with guide sleeve 7 and lower guide sleeve 8, described to lead
Be provided with oil inlet passage 9 on set 2, the oil inlet passage 9 be in using the A points on scraper bowl cylinder cylinder barrel 1 as 1/4 arc-shaped in the center of circle,
It is provided with packing chamber 10 and lower packing chamber 12 between the upper guide sleeve 7 and lower guide sleeve 8, is arranged in the upper seal washer 10
There is upper seal washer 11, lower seal washer 13, the boundary of the upper seal washer 11 and lower seal washer 13 are provided in the lower packing chamber 12
Face is in equilateral hexagon.
One face of the upper seal washer 11 is connected on piston rod 3, and the face parallel with one face is connected to
In the vertical wall of packing chamber 10, face that the upper packing chamber 10 is mutually parallel abut the equilateral hexagon respectively two are opposite
Vertex.
One face of the lower seal washer 13 is connected on piston rod 3, and the face parallel with one face is connected to down
In the vertical wall of packing chamber 12, face that the upper packing chamber 12 is mutually parallel abut the equilateral hexagon respectively two are opposite
Vertex.
The interface of upper seal washer 11 and lower seal washer 13 is arranged to equilateral hexagon, and a face of upper seal washer 11 is supported
