れる。2. Description of the Related Art A conventional scoop of this type is shown in FIG. That is, it is composed of a sword tip 1, a handle 2 and a handle 3, and is used for work such as excavation or dredging.

大きな負担を強いると言った問題点があった。However, in such a conventional technique, when excavating the scoop with a scoop, when the operator scoops up the soil, the operator has only a handle 2 and a handle 3 and is shallow. This is not the case when digging a hole, but even when digging a deep hole, one hand tries to hold the handle 3 at the end of the handle 2 and the other hand as close as possible to the sword tip 1. Then, the upper body of the worker has to take a forward bending posture deeply, and after the motion of throwing away the object to be scooped next, the worker takes a raised posture. As described above, the excavation work involves repeated bending and stretching of the upper body by applying a load to both hands, which poses a problem that it imposes a heavy burden on the waist of the worker.

難であるという問題点があった。Further, when excavating a deep and narrow hole or when dredging a drainage basin, the sword tip 1 of the scoop is to be inserted deeply, and the hand of the operator on the ground has a portion close to the sword tip 1. I can't. There is a problem that such a work with a scoop is extremely difficult because a large force is required to act on the tip 1 of the handle 2 by holding the portion far from the tip 1 of the handle.

23を設けてある。The annular hook 22 is fixed by welding in parallel with the longitudinal direction of the handle 12. The rope 21 is attached to the annular hook 22 at the front end 21a of the handle 12 so that the tip 21a of the rope 21 for operation can be fixed and pulled during excavation to apply force to the tip 11 of the sword. A rope 23 is provided along the middle portion of the rope 21 while being fixed along the triangular space of the base end portion 21b of the rope 21.

で可能なこの動作は全て違和感無くできる。FIG. 6 shows a pot digging operation. In FIG. 6, when excavating using the scoop 10, the operator holds the handle 13 with both hands and pushes the tip 11 of the sword into the soil,
Put one foot on the shoulder 11c of the sword tip 11 and tip 1 of the sword tip 11
Push 1b into the soil. Next, when a force to push down the handle 13 is applied, the handle 13 is used as a force point, a part of the back of the sword tip 11 is used as a fulcrum, and the sword tip 11 is used as an action point.
The sword tip 11 is raised, the soil on the front surface of the sword tip 11 is cut off from the other, and is scooped on the rake face 11a. All the operations that can be performed by the conventional technique can be performed without a feeling of strangeness.

ている。In FIG. 6, the grip 13 is then gripped by one hand and the grip 23 of the rope 21 is held by the other hand to scoop up the excavated soil. At this time, since the upper body of the worker does not bend forward significantly, the burden on the waist is small. Further, the handle 23 can be surely held with a small grasping force as compared with the case where the rope 21 is directly held, which reduces the burden on the operator.

へはねることもできる。In FIG. 6, subsequently, the handle 13 is held with one hand.
Grasp and scoop up the scooped soil without changing the grip while holding the handle 23 of the rope 21 with the other hand. At this time as well, the upper body of the worker does not greatly bend forward, so that the waist is less likely to be overloaded. In addition, the elasticity of the rope 21 can be used to give momentum to the sword tip 11 to splash the scooped soil further.

ない。In FIG. 6, as the drilling bottom becomes deeper,
The tip A of the handle 12 is underground, and the worker on the ground is the handle 12
It is in a state where it is not possible to hold the tip A of the. If you try to forcibly hold it, your posture will become unstable and the force will be diminished, and if you had a part that the operator could reach, the force acting on the sword tip would be small, and there would be sufficient force at the point of action. Does not work.

I am raising. The rope 21 extends to form a triangle,
The force applied to the tip portion acts on the solidified portion A of the rope 21, and the sword tip 11 that has scooped up the soil can be easily pulled up.

上げられる。The rope 21 is extended by the pulling force, and there is a degree of freedom in the direction of the pulling force. When the operator pulls up the handle 23 in the upward direction of the right hand with the handle 13 of the left hand as a fulcrum, the moment becomes large, and the handle 23 is pulled up more lightly than in the direct upward direction.

In FIG. 7, in the case of the dredging work of a narrow deep hole such as a drainage basin or a gutter, the tip A of the handle 12 is underground, and a worker on the ground cannot hold the tip A of the handle 12. . If you try to forcibly hold it, your posture will become unstable and the force will be diminished, and if you have a part that the operator can reach, the force acting on the sword tip will be small, and there will be no sufficient force at the point of action. Does not work Therefore, the conventional technique is not suitable for such work.

I am raising. The rope 21 extends to form a triangle,
The force applied to the tip portion acts on the solidified portion A of the rope 21, and the sword tip 11 that has scooped up the soil can be easily pulled up.

After passing through the annular hook 22A, the rope 21 is rotated around the rear surface of the connecting portion A of the handle 12 with the sword tip 11 and fixed again through the annular hook 22b. In addition, the rod-shaped member 2 is provided near the center of the rope 21.
3a is provided as a handle 23.

ロープ21の取り付け方法を排除するものではない。In the above embodiment, the handle 12 and the sword tip 11 are used.
An annular hook 22 is fixed by welding to a connecting portion A with which the operation rope 21 is fixed to the annular hook 22.
The rope 21 is shown as being fixed at its base end through a rectangular space, but the method of attaching the annular hook 22 and the rope 21 by means other than this is not excluded.
【0035】例えばロープ21は柄12と剣先11との
