FIG. 1 is a perspective view showing a state in which a groove 5 is excavated by a working machine to which a bucket with a groove excavation depth measuring instrument according to one embodiment of the present invention is attached, and FIG. 2 shows a bucket with a depth measuring instrument and a water thread. FIG. 3 is an explanatory view showing the relationship, FIG. 3 is an explanatory view showing a state in which the groove 5 is excavated by a bucket with a depth measuring instrument, and FIG. 4 is an excavation along a water thread stretched to intersect with each other. It is explanatory drawing which shows the state.

First, the bucket with a groove excavation depth measuring instrument of the present invention will be described. That is, as shown in FIG. 1, the working machine such as a server Kkufo is shown as reference numeral 1. The work machine 1 excavates the ground using the bucket 4 when performing, for example, a foundation work for a detached house.

The bucket 4 is attached to the tip of an arm 2 having a first arm 2a, a second arm 2b and a third arm 2c, one end of which is attached to the main body of the working machine 1.

These individual arms are composed of rotary shafts 3a, 3
b, 3c (partly not shown), and the rotary shafts 3a, 3 are connected by the cylinders that drive the arms.
Various movements can be given to the bucket 4 by rotating around b and 3c and performing a combined movement of each arm.

For example, when excavating a groove 5 of a predetermined depth in a predetermined area of the ground GL with the bucket 4, the toes 6 of the bucket 4 are fed into the ground GL to move the rotary shaft 3c.
While rotating the toe 6 around the center, the groove 5 having a predetermined depth is gradually formed.

In order to form the bottom surface of the groove 5 into a uniform flat plane, in addition to the pivotal movement about the pivot shaft 3c, at least the forward / backward movement by the respective arms 2b, 2c is added, and the toe 6
It is performed while moving horizontally.

Therefore, when a member having an arc of radius R centering on the toe 6 is attached to the rear end side of the bucket 4, when the bucket 4 is rotated and moved back and forth, the bottom surface of the groove is horizontally excavated. It can be seen that the outer circumference of the arc is always constant with respect to the virtual horizontal line on the ground GL.

From this, the radius R from the toe 6 to the outer periphery when the above-mentioned arc member is attached is taken into consideration the depth of the groove excavated in the ground GL, that is, the height h of the water thread from the ground h. And the depth of the groove to be excavated, and when the toe 6 is located at the bottom of the excavated groove, it is stretched at a predetermined height position h on the ground GL so that the water threads come into contact with the outer circumference of the arc. It is possible to excavate a groove with a certain depth based on the water thread.

Therefore, the circular arc member is configured as the depth measuring instrument 8 and is previously configured as a pair of depth measuring instruments 8a and 8b for each radius R corresponding to various groove depths defined by the building standards. .

The depth measuring devices 8a and 8b are composed of a pair of fan-shaped plate-like members, and are detachably attached to both sides of the rear end portion of the bucket 4.

On the other hand, as shown in FIG. 4, the periphery of a predetermined region where a plurality of trenches 5 are excavated is, for example, each plate member held by a plurality of piles 12 erected on the ground GL so as to have a rectangular shape in plan view. It is surrounded by 11a, 11b, 13a, 13b.

A plurality of water threads 9a, 9a are provided on each of the facing piles 12.
b and 10a, 10b correspond to the trench 5 to be excavated,
The direction along the longitudinal direction of the groove 5 or both ends of the groove 5 are stretched on the same horizontal plane so as to be orthogonal to the longitudinal direction.
As shown in, the height h above the ground GL is set as the length of the difference obtained by subtracting the groove depth Δh to be excavated from the radius R (= H) to which the depth measuring instrument 8 is attached.

Next, a groove excavation method using a bucket with a groove excavation depth measuring device will be described. First, the peripheries of the regions where the plurality of trenches 5 are excavated are the respective plate members 11a, 11b, 13a, 1
When surrounded by a rectangle 3b, the grooves 5 in which the respective water threads 9a, 9b and 10a, 10b should be excavated in the pile 12 supporting these plate materials.
Corresponding to the above, it is stretched on the same horizontal plane at a direction along the longitudinal direction of the groove 5 or at both ends of the groove 5 so as to be orthogonal to the longitudinal direction.

The height of each water thread is as described above. The height above the ground GL is the radius R (= H) to which the depth measuring devices 8a and 8b are attached, and the groove depth Δh to be excavated is subtracted. Is set as the difference.

Therefore, when the working machine 1 is operated to excavate the first groove, as shown in FIG. 4, for example, the excavation is started from the left side of the area surrounded by the plate materials and moves to the right side. , The bucket 4 at the starting position (left end) is
Although not shown, the main body of the working machine 1 is located at the upper part of the drawing, and at this position, the depth measuring instrument 8a attached to one side of the bucket 4 is used as a reference with the left side water thread 10b stretched in the vertical direction. Excavation proceeds.

When the outer circumference of the depth measuring instrument 8b on one side is excavated up to the position where the water thread 10b on the left side is excavated, it can be seen that the desired depth Δh has been reached (see FIG. 3).

Next, when excavation is promoted while moving the bucket 4 to the right, the depth measuring instrument 8a on one side causes the water thread 10 to move.
When it comes off from b, the depth measuring devices 8a, 8 on both sides of the bucket 4
Excavation is performed using the water thread 9a, which has the outer circumference of b stretched in the lateral direction, as a reference.

Subsequently, when the bucket 4 moves to reach the right end of the groove 5, the depth measuring device 8b attached to the opposite side of the bucket 4 is vertically stretched to extend the water thread 10a on the right side.
Excavation is carried out on the basis of.

In this way, the groove 5 having the desired depth Δh is excavated. Therefore, the outer circumferences of the depth measuring instruments 8a, 8b having a predetermined radius R attached corresponding to the depth of the groove excavated by the bucket 4 serve as a reference stretched at a predetermined height position h on the ground GL. Water threads 9a, 9b and 10a, 10
By excavating the groove 5 so as to be located at position b, the depth Δh of the preset depth Δh is not affected by the unevenness and ups and downs of the terrain, and does not require the skilled person to operate. The groove 5 can be excavated to a certain depth, and the work efficiency can be improved.

Next, another embodiment of the present invention will be described. FIG. 5 is an explanatory view showing a state in which the bottom surface of the bucket is set horizontally by the level bar and the water thread according to another embodiment. Regarding the same components as the above components,
The same reference numerals are given and detailed description is omitted.

In this embodiment, a level bar 14 having a predetermined length is attached to one end or both ends of a rotating shaft 3c on which the bucket 4 is rotatably supported.

Specifically, one ends of a pair of level bars 14 attached to both ends of the rotating shaft 3c are attached in parallel with the bottom surface 4a of the bucket 4 so as to rotate in synchronization with the bucket 4.

Therefore, when carrying out earthmoving using the bottom surface 4a of the bucket 4, the bucket 4 is rotated by the rotating shaft 3c.
The level bar 14 is rotated about the
By matching with a or 10b, the bottom surface 4 of the bucket 4
a is set parallel to the ground GL.

Thus, the bottom surface 4a of the bucket 4 can be set in parallel with the ground GL in a short time by an extremely simple operation, and the leveling operation of the bottom surface 4a of the bucket 4 can be performed.
