Abstract
A bucket of a type designed to attach to the stick of an excavator, using pre-existing pins. The bucket is powered by a hydraulic cylinder, the lines of which attach to excavator controls. Striker forks are mounted onto the stick of the excavator at a predetermined position. The clean-out system is a wiper plate incorporated into the bucket as the “roof”, which is designed to follow the inner contour of the sides of the bucket. As the bucket is filled, the wiper plate moves to the top of the bucket; when the bucket is emptied, the wiper plate contacts the striker forks, which force the material out of the bucket, preventing build-up of material on the inside of the bucket.
Claims4
A hydraulic, self-cleaning bucket assembly for attachment to a stick assembly of an excavator, wherein the self-cleaning bucket assembly comprises:
- a bucket comprising two sidewalls, a contoured bottom, and two square tubing pieces, all welded together to form the bucket;
- a wiper plate rotatably mounted onto one of the square tubing pieces, said wiper plate being movable through a 135° arc and having an edge movable along the contoured bottom;
- means for mounting the bucket onto the stick assembly;
- a striker assembly separately mounted onto the stick assembly, said striker assembly being positioned to stop rotation of the wiper plate past a predetermined point as the bucket continues to rotate when said bucket is being emptied;
- a hydraulic cylinder with a manifold and a line, said hydraulic cylinder effectuating rotation of the bucket.
