A bucket equipped for use with an excavation machine for improvement of ground, the bucket comprising:
- a pair of side plates defining a pair of opposing side surfaces,
- a bottom plate defining a bottom surface having at least one opening through which ground can be discharged;
- excavating edge means on said bottom surface for excavating the ground and for enabling at least a portion of the excavated ground to be scooped into the bucket;
- said excavating edge means comprising a plurality of excavating pawls;
- mixing means for mixing the ground excavated by said excavating edge means in the bucket;
- said mixing means being disposed in the bucket between said excavating edge means and said at least one opening such that ground excavated and scooped into the bucket using said excavating edge means can be mixed by said mixing means, and then discharged through said at least one opening.
An excavation machine for improvement of ground, said machine comprising:
- a) a bucket which comprises:
- i) a pair of side plates defining a pair of opposing side surfaces;
- ii) a bottom plate defining a bottom surface having at least one opening through which ground can be discharged;
- iii) excavating edge means on said bottom surface for excavating the ground and for enabling at least a portion of the ground so excavated to be scooped into the bucket;
- said excavating edge means comprising a plurality of excavating pawls;
- iv) mixing means for mixing the ground excavated into the bucket;
- said mixing means being disposed in the bucket between said excavating edge means and said opening such that ground excavated and scooped into the bucket using said excavating edge means can be mixed by said mixing means and then discharged through said at least one opening;
- and
- b) means for moving the bucket to cause the bucket to excavate the ground and to scoop the excavated ground into the bucket such that the excavated ground so scooped can be mixed by said mixing means and then discharged through said at least one opening.
A bucket equipped for use with an excavation machine for improvement of ground, the bucket comprising:
- a pair of side plates defining a pair of opposing side surfaces;
- a bottom plate having a front portion and a rear portion with an opening therein;
- excavating edge means on said front portion for excavating the ground and for enabling at least a portion of the excavated ground to be scooped into the bucket, said excavating edge means comprising a plurality of excavating pawls;
- mixing means for mixing the ground excavated by said excavating edge means in the bucket, said mixing means being disposed in the bucket between said excavating edge means and said rear portion such that ground excavated and scooped into the bucket using said excavating edge means can be mixed by said mixing means, and then passed to said rear portion, said rear portion comprising surface means for allowing a first portion of ground passed to said rear portion to be discharged through the opening while maintaining a second portion of ground passed to said rear portion in the bucket.
