5.2 Bucket
5.2.1
1) The longitudinal profile of bucket meets the law of motion of various materials
inside of bucket, facilitating the material flow and minimizing the loading resistance
and thus fulfilling the bucket.
2) Bucket teeth are mounted to increase the linear specific pressure of bucket onto
material, with unit Icutting resistance relatively low and easing to cut in and break soil.
In addition, the teeth are resistant to wear and easy to replace.
3) The load is easy to get off, shortening the unloading time and increasing the
effective capacity of bucket.
5.2.2
Bucket shape and size for backhoe are highly related to work objects. In order to
meet various excavation, one excavator could be equipped with multiple types of buckets,
with backhoe most popular. Bucket tecth could be mounted with rubber pins and bolts.
Connection between bucket and hydraulic cylinder is of linkage mechanism, with
bucket direct articulated with hydraulic cylinder, which drops the rotation angle of bucket
but enables the work torque to change greatly..
