DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket of an excavating machine such as a backhoe and a power shovel.

[0002]

Conventionally, as this kind of drilling machine of the bucket
Te, is known as the opening edge of the bucket body is box-shaped having a drilling blade at the bottom of the opening edge exhibits a rectangular
However, the bucket of this excavator
Since the left and right sides of the mouth are vertical,
U-shaped groove with vertical wall on both sides and L-shape with vertical side wall
It is convenient to excavate a groove, but it has a V-shaped
Excavation of trapezoidal grooves, trapezoidal grooves or angled sections with inclined walls
Is not always convenient for creating sloped walls
And the volume of the bucket body is constant,
There is a limit to the amount of other things that can be picked up,
May be inconvenient for
Excavation from inside the bucket body when the entire peripheral wall consists of a plate-like wall
Excavation sticks to the inner wall when releasing things, etc.
There was a defect such as remaining.

[0003]

The present invention solves the above deficiencies.
Of new excavation equipment that has been
The purpose is to provide a ket.

The left and right arm members 10 and 11 projecting to the left and right
2 and detachably fixed by 2
The front part of both right edges and the tip of the left and right bilateral arm members 10 and 11
Excavating blades 13 and 14 on the left and right sides are placed outside.
And the lower ends of the left and right side excavating blades 13 and 14 to the bottom surface
Left and right hinges 1 in front of left and right edges of wall 3
5 and 16 so as to be rotatable in the left-right direction.
Left and right arms on upper part of left and right side excavating blades 13 and 14
Removably fixed to the tips of members 10 and 11 with screws 17
And the left edge of the support member 4, the left arm member 10 and
Left side part 18 surrounded by left side excavating blade 13
On the left side net made of metal chain via U-link 19
The member 20 is stretched detachably, and the right side of the support member 4 is
Edge, right arm member 11 and right side excavating blade 14
Via the U-link 19 to the right side area 21 surrounded by
The right net-like member 23 made of a chain is stretched detachably.
And a bottom excavation plate 25
It is obtained by the.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, a steel plate is used to
A support member 4 composed of a back wall portion 2 and a bottom wall portion 3 is formed.
Bearing part 8 for connection to arm 6 and cylinder 7 of
9 and the left and right arm members 1 projecting left and right at front portions of both left and right edges of the upper surface wall 1 of the support member 4.
0 and 11 are detachably fixed by screws 12, and left and right sides are excavated in front of the left and right edges of the bottom wall 3 of the support member 4 and outside the front ends of the left and right arm members 10 and 11. The blades 13 and 14 are arranged in the passing state, and the lower ends of the left and right side excavating blades 13 and 14 are rotated in the left and right directions via left and right hinges 15 and 16 in front of the left and right edges of the bottom wall 3. The left and right side excavating blades 13 and 14 are detachably fixed to the tips of the left and right arm members 10 and 11 by screws 17 while being left and right, and the left edge of the support member 4, the left arm member 10 and Left side excavation blade 1
A left net-shaped member 20 made of a metal chain is stretched through a U-link 19 at a left portion 18 surrounded by 3,
A right net-like member 2 made of a metal chain is connected via a U-link 19 to a right portion 21 surrounded by a right edge of the support member 4, a right arm member 11, and a right side excavating blade 14.
3 and the bottom wall 3 of the support member 4
Is a bottom excavation plate 25 with a tip 24.

[0006] Reference numeral 27 denotes a left-right arm elongated member, to hold the wide state in which the left and right drilling blades 13, 14 outwardly to further inclined as indicated by a virtual 1 It is for. When the wide state is set in this way, the left and right net-like members 20 and 23 may be replaced by a separately prepared wide area member by attaching and detaching the U-link 19, and the wide state is also supported from the beginning. It may be of a size that can be stretched. In the above embodiment, the portion composed of the support member 4, the arm members 10, 11 and the net members 20, 23 forms a bucket body. In addition, at the time of implementation, three or more types with different lengths
Provide the upper arm member to adjust the inclination angle of the left and right
Be able to make small changes.

[0007] Another embodiment shown in FIG.
An upright wall 28 is provided on both right side edges.

As described above, the opening edge of the bucket body
Digging blades 13 and 14 on the left and right sides
The gap between the upper ends of the left and right side excavating blades 13 and 14 is wide and lower.
Take the inclined state and the excavated material with a narrow end into the bucket body.
The left and right side excavation of these inclined states
By using blades 13 and 14 for dexterity, inclined wall
V-shaped groove, trapezoidal groove or angled section with inclined wall
When digging, etc., it is easy to create sloped walls,
Adjusting means of the inclination angles of the left and right side excavating blades 13 and 14
Provided that the sloped wall is
Left and right side excavation blades 13 to match the inclination angle of the surface,
It is possible to change the inclination angle of 14 and it is easy to use
And excavation on the left and right sides of the wall of the bucket body
The part located behind the blades 13 and 14 is a net
Since the members 20 and 23 are constituted by the stretching means, the bucket
When excavating objects are released from the main body,
The excavated material swings (vibrates) in the bucket body.
Etc. can be prevented from sticking and remaining
You.

[0009]

As described above, the bucket of the excavating machine according to the present invention is suitable for forming not only a groove having a vertical wall surface but also a groove portion having an inclined wall surface and a mountain-shaped portion, thereby improving the efficiency of the forming operation. In addition, in such a formation, the inclination angles of the left and right side excavating blades 13 and 14 can be appropriately adjusted to the angles of the formed slopes, so that it is extremely easy to use. Can be changed by adjusting the inclination angle of the left and right side excavating blades, which is useful and convenient for loading and transferring operations, and it is difficult for burrs to remain in the bucket body when excavated materials are released. Ah is, also the arm member in the present invention
And because the net-like member is detachable,
Multiple types of arm members with different lengths and mesh sizes
Prepare multiple types of net-shaped members with different sizes
If, in use in accordance with the arbitrary shape and soil such as reclamation groove
The above-mentioned ease of use is further improved, especially
Since it has a net member, it is suitable for soil containing water.
