PURPOSE:To cause direct flowing of excavated soil and sand in a backhoe bucket for conveyance and to improve an excavating efficiency, by a method wherein a hole is machined in the bottom plate of the bucket, and a fluid conveying device, consisting of a casing and an impeller, is attached to the outside of the bucket. CONSTITUTION:A hole 4 is bored in a bottom plate of a bucket 2 of a backhoe 1, and a fluid conveying device 3 is attached. The fluid conveying device 3 consists of an impeller 5, a casing 6, and a motor shaft 11, water or air is fed into the fluid conveying device 3 through a flow path 7, and soil and sand, excavated by the bucket 2, is fed into the impeller 5 through the hole 4 to convey soil and sand with fluid pressure. The fluid conveying device 3 is coupled to the hole 4 in the bucket 2, and this enables flowing of soil and sand for conveyance directly to another place through the working of the fluid conveying device 3 without moving of the excavated soil and sand in the bucket 2 to another conveying means, which results in improving an excavating efficiency. |
