BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction of a bucket applied to a construction and civil engineering machine device such as a back hoe in an excavator type excavator. The present invention relates to a novel combination of a perforated bucket and a non-perforated bucket which can be used by changing one bucket to a skeleton type perforated bucket and a non-perforated bucket.

[0002]

2. Description of the Related Art As is well known, in construction and civil engineering works, a very large variety of excavation works such as rock excavation, open cuts on roads, opening of waterways, or breaking of existing structures are carried out. Various types of excavation and loading machines are used to remove the soil and rocks associated therewith, but the applicable model may need to be changed depending on the type of excavation target and its condition. In such cases,
Naturally, I had to change the type of bucket.

Conventionally, in excavator excavators for construction and civil engineering work, for example, a bucket applied to a backhoe or the like is exclusively for excavating, loading the excavated product as it is, and moving it to another place. An excavation / loading type non-perforated bucket used (a bucket with no holes in the bucket floor),
The skeleton type perforated buckets (buckets having a grid-shaped hole on the bucket floor) for excavating, excavating excavated materials, and moving only those that need to be moved are roughly classified.

The above-mentioned conventional buckets, whether they are non-perforated buckets or perforated buckets, are constructed and provided as individual ones, and are provided for the purpose of use as described above. Had to prepare a device with two types of buckets in advance. This is extremely economically unreasonable, and many problems such as storage space have been pointed out.

[0005]

[Problems to be solved by the device]
It has a simple structure, is easy to manufacture, is suitable for mass production, has excellent operability and handling, and can be changed to the above-mentioned two kinds of usage modes by an extremely simple operation. An object of the present invention is to provide a perforated bucket / non-perforated bucket combination which can be adapted.

[0006]

In order to achieve the above-mentioned object, the present invention specifically has a bucket surface having a curved surface, a pair of bucket side walls and a bucket top wall, and the bucket floor is , A plurality of vertical rims extending along a plurality of planes parallel to the pair of bucket side walls, and a plurality of horizontal bars extending between the pair of bucket side walls. A skeleton-type perforated bucket body formed by forming a grid-like hole with a bar, and a curved surface-shaped plate body that engages along the inner wall surface of the bucket floor in the skeleton-type perforated bucket body. A combination with a non-perforated bucket forming member for completely closing a mesh-shaped hole in the perforated bucket main body, the non-perforated bucket forming member with respect to the perforated bucket main body First to detachably fixedly coupled
Of the perforated bucket main body so as to fit the front edge of the non-perforated bucket forming member. The second fixing portion of the fixing means is a fitting groove provided along the front edge side of the bucket floor, and the first pin insertion holes provided in the plurality of vertical rims of the perforated bucket body, and the perforated hole. A pair of second pin insertion holes that are provided on the back surface side of the non-perforated bucket forming member so as to be able to come into surface contact with the vertical rim of the bucket body and that have second pin insertion holes that match the first pin insertion holes. A bracket and a connecting member fitted into the aligned first pin insertion hole and second pin insertion hole, and the non-perforated bucket forming member is fixed to the perforated bucket body via the fixing means. Upon binding, it constitutes imperforate bucket, when removed the imperforate bucket forming member is a perforated bucket Kenmuana bucket combination body without so as to form a perforated bucket.
