PURPOSE:To permit a wide range of operation for a bucket type lake attached to an earthwork vehicle by using a lake body with a lower jaw consisting of plural lakes and a bucket body with an upper jaw consisting of cutting edges. CONSTITUTION:A lower jaw 2 attached to a fitting mechanism and an upper jaw 6 pivotally supported by a hinge 4 on the lower jaw 2 are opened or closed by a liquid-pressure cylinder 8. The lower jaw 2 consists of a side plate 12, a back plate 10, and a lake body with plural lakes 14 arranged sideways with a spacing, and the upper jaw 6 makes up a bucket body having a front cutting bar 36 with a cutting edge 40, a side plate 42, and a bottom plate 44. When using the bucket type lake for cleaning sea side areas, the upper jaw 6 is greatly opened in relation to the lower jaw 2, and also when using it for collecting rocks, etc., the upper jaw 6 is closed and the lake is used as in the case with the usual bucket. Also, when moving long materials by it, they are clutched by both the upper and lower jaws 6 and 2 and moved. |
