As preferred plan; Direction with near the piston rod of said bucket cylinder is inside direction; The upper end of said bucket comprises an interior connecting portion and an outer connecting portion; Connecting portion is connected with said connecting rod through said revolving joint in said, and said outer connecting portion is connected with the lower end of said support through said revolving joint; The hypomere of said bucket comprises a rectangle outerplanar and two triangle transverse planes, and two said triangle transverse planes lay respectively at the outerplanar two ends of said rectangle and vertical with said rectangle outerplanar; The position of two said buckets meets the following conditions: the piston rod of said bucket cylinder is descending put in place after; Said rectangle outerplanar is in vertical direction; The piston rod of said bucket cylinder is up put in place after, the inner edge of the corresponding triangle transverse plane of two said buckets closely contacts and is in vertical direction.Above-mentioned bucket structure not only can be cheated the requirement of excavation in the side of satisfying, and passes through the keying that hydraulic pressure is realized bucket, and its control is accurate and can satisfy the square hole excavation requirement under the high centrifugal field condition.According to actual application environment, bucket also can be other concrete structure, such as adopting a bucket and a plate bucket that has inner chamber, perhaps adopts the bucket of other polygon transverse plane, or the like, specifically select according to actual conditions.
As preferably, said revolving joint is a hinge.
The beneficial effect of the utility model is:
The utility model can satisfy the structural limitations of geotechnical centrifuge; Can adapt to the reasonable excavation work of high centrifugal field again; Can be used for hole, geotechnical centrifugal model test simulation side digging process, can adopt repetitive operation to cheat the body expansion, have the advantage that the excavation size is big, be convenient to regulate; Increase the authenticity of hole, the side digging process among the geotechnique, filled up the dig pit blank of function of Chinese domestic geotechnical centrifuge manipulator.
