[Detailed description of the invention]

The present invention relates to an earth and sand carrying bucket, and more particularly to an improved bucket for carrying earth and sand, such as excavated soil from standing piles, in a building or civil engineering work, to a truck bed or another place.

[0002]

[Prior art]

 Ordinary sediment discharge buckets commonly used include orange peel buckets, boat-shaped buckets, wire mocks, guide rail type buckets, etc. A boom mounted on a turntable rotatably mounted on a crawler is rotated by a hydraulic cylinder and driven by a hydraulic cylinder to the tip of an arm rotatably connected to the tip of the boom. A vehicle device is used in which a shovel is mounted and earth and sand are loaded into the bucket.

[0003] When loading earth and sand such as excavated soil from standing piles into a carry-out bucket at a construction site, by driving the power shovel, the shovel rotates with the vertical movement of the boom and the arm, By rotating the turntable, the excavated earth and sand is loaded into the carry-out bucket within a circle of a predetermined radius centered on the crawler, and then the excavated earth and sand is lifted and moved by the crane to move the excavated earth and sand into the truck. It can be transported to the loading platform or other places.

[0004]

[Problems to be solved by the invention]

 In such a conventional earth and sand discharging bucket, there are many cases where the operation of loading the earth and sand is not always smooth, and there is a problem that the earth and sand is spilled from the bucket at the time of unloading. There is a problem in that it is necessary to have a plurality of workers who monitor the operation of the robot and give instructions to the operator, and it is difficult to improve work efficiency.

[0005] Particularly, when a bucket that is not a bottom-open type is used, it is difficult to discharge the earth and sand after unloading, and it is not possible to adjust the amount of earth and sand discharged from the bucket during unloading. There is a problem that the quantity is too large or too small, and the problem remains that the optimal amount of earth and sand cannot be carried out to the target place such as the truck bed and the work accuracy is reduced.

Therefore, the present invention solves the problems of the conventional earth and sand carrying bucket, and makes it easy to load earth and sand into the bucket and discharge the earth and sand after being carried out. It is an object of the present invention to provide a sediment carrying bucket capable of adjusting the amount of sediment discharged from the crane and loading / discharging the sediment into / from the bucket smoothly by a crane operator alone.
