Abstract

PROBLEM TO BE SOLVED: To make the mud cutting of a bucket good in a civil engineering machine by disposing a mud cutting member made of rope-like material such as a chain in a contiguous and loosened state along the inside wall faces of a bucket main body. SOLUTION: A mud cutting member 14 formed by arranging a number of pieces of chains in a lattice-like manner and joining their intersectional points mutually is disposed in a contiguous and loosened state along the inside wall faces of upper and lower and rear faces of wall parts of a front face-opened type bucket main body 6, the four corners of which are secured to the parts near the opened side end peripheries of the upper and lower face wall parts 1, 3. Furthermore, a long arcuate leaf spring 15 is set to the opened side periphery of the lower face wall part 3 from the upside part of the rear face wall part 2; which whose lower end is fastened to the lower face wall part 3. When sediment is discharged from the bucket main body 6, the mud cut member 14 moves to come off the wall face of the bucket main body 6 by the agency of operation force of mud discharge force or reaction and the leaf spring 15, so that mud and sediment can be readily scraped down therefrom.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket for an earth-moving machine such as an excavating machine, which has a good dro separation.

[0002]

2. Description of the Related Art A bucket of this kind, which is widely used, has a drawback of sticking to the inner wall surface of the bucket after the contents are discharged. It was also a cause.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, an object of the present invention is to provide a bucket for a new earth-moving machine such as an excavating machine, which has been devised to automatically and effectively separate a mud. It is.

[0004]

In order to achieve the above-mentioned object, a bucket of an earth-moving machine such as an excavating machine according to the present invention has a string-like shape such as a chain arranged in a state along the inner wall surface of the bucket body and in a slack state. The device comprises a dropper made of a material and a spring for applying a force to the dropper in a direction away from the inner wall surface of the bucket body.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, a steel plate is used to
An open front bucket body 6 comprising a back wall portion 2, a bottom wall portion 3, and left and right side wall portions 4, 5 is formed. An arm 8 of an excavating machine 7 is provided outside the top wall portion 1 of the bucket body 6.
And connecting bearings 10 and 11 for the cylinder 9 and a plurality of claw members 12 attached to the opening edge of the lower surface wall 3 and, separately from this, a large number of chains arranged in a grid pattern and Are fixed to each other to form a dropping member 14, and the dropping member 14 is arranged in a state along the inner wall surfaces of the upper, lower, and rear wall portions of the bucket body 6 and in a state where there is a slack. The four corners are fastened to the positions near the open side edges of the upper and lower wall portions 1 and 3 and are long arcuate positions extending from the upper side portion of the rear wall portion 2 to the portion near the open side edge of the lower surface wall portion 3. A leaf spring 15 is disposed and the lower end of the leaf spring 15 is fixed to the lower surface wall portion 3. The leaf spring 15 is located between the wall surface of the bucket body 6 and the dropping member 14, and The drop member 14 is separated from the wall surface of the bucket body 6 It is obtained so as to impart a force in the direction.

That is, when a mud enters the bucket body 6, the mud dropping member 14 is tightly attached to the wall surface of the bucket body 6 without being separated by the force of the mud, and the mud comes out of the bucket body 6. Sometimes, the drop dropping member 14 moves away from the wall surface of the bucket body 6 due to the pulling force and reaction and the action force of the leaf spring 15.

[0007]

The bucket of the earth-moving machine such as an excavating machine according to the present invention has the above-mentioned structure, so that when the scooped mud or the earth and sand is discharged, the mud dropping member moves freely and sticks to the wall surface. It sweeps mud and earth and sand, and has a remarkable effect to completely achieve its intended purpose.

The present invention provides, for example, a string-like material such as a soft wire instead of a chain, a drop-out member using a synthetic resin net having a large eye, or a stretchable string instead of a leaf spring. For example, various modifications can be made without departing from the spirit of the present invention, and the present invention covers the modified ones.
